NSIS WriteIniStr - nsis

I am trying to overwrite an existing value in my Application .config file using NSIS.
I want to change 'endpoint address="http://DefaultWebService.asmx"'
to 'endpoint address="http://MyWebService.asmx"'
My Config file looks something like this:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>
<client>
<endpoint address="http://DefaultWebService.asmx"
binding="customBinding" bindingConfiguration="MyServiceSoap12"
contract="WebServiceProxies.MyServiceSoap" name="MyServiceSoap12" />
</client>
</system.serviceModel>
</configuration>
In my NSIS I'm using :
WriteIniStr "$MyApp.exe.config" "system.serviceModel" "endpoint address" "endpoint address="http://MyWebService.asmx"
but this just adds
[system.serviceModel]
endpoint address=http://MyWebService.asmx
to the bottom of the .config file.
Where am I going wrong?
Thanks

The problem is that you're using WriteIniStr which updates .ini files and application.config is an XML file. You need to use something like this plug-in instead.

I was searching whole day about this error and trying to understand FileProvider, but I have no idea what this error message tries to tell me. If you want more info/code, write me in the comment.
Your file is stored under getExternalFilesDir(). That maps to <external-files-path>, not <files-path>. Also, your file path does not contain images/ in it, so the path attribute in your XML is invalid.
Replace res/xml/file_paths.xml with:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-files-path name="my_images" path="/" />
</paths>
UPDATE 2020 MAR 13
Provider path for a specific path as followings:
<files-path/> --> Context.getFilesDir()
<cache-path/> --> Context.getCacheDir()
<external-path/> --> Environment.getExternalStorageDirectory()
<external-files-path/> --> Context.getExternalFilesDir(String)
<external-cache-path/> --> Context.getExternalCacheDir()
<external-media-path/> --> Context.getExternalMediaDirs()
Ref: https://developer.android.com/reference/androidx/core/content/FileProvider
This may resolve everyones problem:
All tags are added so you don't need to worry about folders path.
Replace res/xml/file_paths.xml with:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path
name="external"
path="." />
<external-files-path
name="external_files"
path="." />
<cache-path
name="cache"
path="." />
<external-cache-path
name="external_cache"
path="." />
<files-path
name="files"
path="." />
</paths>
EDIT: 1st June 2021
We should use only specific path which we need.
Try alternate path on your own and use which you needed.
See Accepted answer for more information: https://stackoverflow.com/a/42516202/4498813
Got similar problem after enabled flavors (dev, stage).
Before flavors my path resource looked like this:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path
name="my_images"
path="Android/data/pl.myapp/files/Pictures" />
</paths>
After added android:authorities="${applicationId}.fileprovider"
in Manifest appId was pl.myapp.dev or pl.myapp.stage depends on flavor and app started crashing.
I removed full path and replaced it with dot and everything started working.
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path
name="my_images"
path="." />
</paths>
I am sure I am late to the party but below worked for me.
<paths>
<root-path name="root" path="." />
</paths>
If you are using internal cache then use.
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<cache-path name="cache" path="/" />
</paths>
Lost 2 weeks trying to find some solution... If you arrive here after try everthing above:
1 - Verify if your tag provider are inside tag application
<application>
<provider android:name="android.support.v4.content.FileProvider" android:authorities="com.companyname.Pocidadao.fileprovider" android:exported="false" android:grantUriPermissions="true">
<meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="#xml/file_paths"></meta-data>
</provider>
</application>
2 - If you try a lot paths way without success, then test with this:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<cache-path name="cache" path="." />
<external-path name="external" path="." />
<root-path name="root" path="." />
<files-path name="my_images" path="/" />
<files-path name="my_images" path="myfile/"/>
<files-path name="files" path="." />
<external-path name="external_files" path="." />
<external-path name="images" path="Pictures" />
<external-path name="my_images" path="." />
<external-path name="my_images" path="Android/data/com.companyname.yourproject/files/Pictures" />
<external-path name="my_images" path="Android/data/com.companyname.yourproject/files/Pictures/" />
<external-files-path name="images" path="Pictures"/>
<external-files-path name="camera_image" path="Pictures/"/>
<external-files-path name="external_files" path="." />
<external-files-path name="my_images" path="my_images" />
<external-cache-path name="external_cache" path="." />
</paths>
Test this, if camera works, then start eliminate some lines and continue testing...
3 - No forget verify if camera are actived in your emulator.
Be aware that external-path is not pointing to your secondary storage, aka "removable storage" (despite the name "external"). If you're getting "Failed to find configured root" you may add this line to your XML file.
<root-path name="root" path="." />
See more details here FileProvider and secondary external storage
This confusing me a bit too.
The problem is on "path" attribute in your xml file.
From this document FileProvider
'path' is a subdirectory,
but in another document (camera/photobasics) shown
'path' is full path.
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images" path="Android/data/com.example.package.name/files/Pictures" />
</paths>
I just change this 'path' to full path and it just work.
I would be late but I found a solution for it.Working fine for me, I just changed the paths XML file to:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<root-path name="root" path="." />
</paths>
Check how many storages your device offers - sharing files from secondary storage is not supported. Look at FileProvider.java source (from support-core-utils 25.3.1):
} else if (TAG_EXTERNAL_FILES.equals(tag)) {
File[] externalFilesDirs = ContextCompat.getExternalFilesDirs(context, null);
if (externalFilesDirs.length > 0) {
target = externalFilesDirs[0];
}
} else if (TAG_EXTERNAL_CACHE.equals(tag)) {
File[] externalCacheDirs = ContextCompat.getExternalCacheDirs(context);
if (externalCacheDirs.length > 0) {
target = externalCacheDirs[0];
}
}
So, they take only the first storage.
Also, you can see that getExternalCacheDirs() is used to obtain list of storages through the ContextCompat interface. See documentation for its limits (it's told to not recognize USB Flashes for example). Best is to make some debug output of list of storages from this API on your own, so that you can check that path to storage matches the path passed to getUriForFile().
There's already a ticket assigned (as for 06-2017) in Google's issue tracker, asking to support more than one storage. Eventually, I found SO question on this as well.
I have spent 5 hours for this..
I have tried all the methods above but it depends on the what storeage your app currently using.
https://developer.android.com/reference/android/support/v4/content/FileProvider#GetUri
Check the documentation before trying the codes.
In my case
since files-path sub directory will be Context.getFilesDir().
The funky thing is it Context.getFilesDir() notes one another subdirectory.
what I am looking for is
data/user/0/com.psh.mTest/app_imageDir/20181202101432629.png
Context.getFilesDir()
returns
/data/user/0/com.psh.mTest/files
so the tag should be
....files-path name="app_imageDir" path="../app_imageDir/" ......
Then it works!!
None of this worked for me. The only approach that works is not to declare an explicit path in xml. So do this and be happy:
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images" path="." />
</paths>
Here too has a excelent tutorial about this question:
https://www.youtube.com/watch?v=9ZxRTKvtfnY&t=613s
My issue was that I had overlapping names in the file paths for different types, like this:
<cache-path
name="cached_files"
path="." />
<external-cache-path
name="cached_files"
path="." />
After I changed the names ("cached_files") to be unique, I got rid of the error. My guess is that those paths are stored in some HashMap or something which does not allow duplicates.
This Worked for me as well.Instead of giving full path i gave path="Pictures" and it worked fine.
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-files-path
name="images"
path="Pictures">
</external-files-path>
</paths>
What I did to solve this -
AndroidManifest.xml
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.mydomain.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/filepaths"/>
</provider>
filepaths.xml (Allowing the FileProvider to share all the files that are inside the app's external files directory)
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-files-path name="files"
path="/" />
</paths>
and in java class -
Uri fileProvider = FileProvider.getUriForFile(getContext(),"com.mydomain.fileprovider",newFile);
It depends what kind of storage you want to do, INTERNAL or EXTERNAL
for EXTERNAL STORAGE
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-files-path name="my_images" path="my_images" />
</paths>
but for INTERNAL STORAGE, be careful with the path, because it uses getFilesDir() method
which mean that your file will be located in the root directory for the app ("/")
File storeDir = getFilesDir(); // path "/"
So your provider file must be like this:
<paths>
<files-path name="my_images" path="/" />
</paths>
Change your main/res/xml/provider_paths.xml
From
<paths>
<files-path path="images/" name="myimages" />
<external-path name="download" path="download/"/>
</paths>
To
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path
name="external"
path="." />
<external-files-path
name="external_files"
path="." />
<cache-path
name="cache"
path="." />
<external-cache-path
name="external_cache"
path="." />
<files-path
name="files"
path="." />
</paths>
I had the same problem, I tried the below code for its working.
1.Create Xmlfile : provider_paths
<?xml version="1.0" encoding="utf-8"?>
<paths>
<files-path name="my_images" path="myfile/"/>
</paths>
2. Mainfest file
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.ril.learnet.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
3.In your Java file.
File file = new File(getActivity().getFilesDir(), "myfile");
if (!file.exists()) {
file.mkdirs();
}
String destPath = file.getPath() + File.separator + attachmentsListBean.getFileName();
file mfile = new File(destPath);
Uri path;
Intent intent = new Intent(Intent.ACTION_VIEW);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N)
{
path = FileProvider.getUriForFile(AppController.getInstance().getApplicationContext(), AppController.getInstance().getApplicationContext().getPackageName() + ".provider", mfile );
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
} else {
path = Uri.fromFile(mfile);
}
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setDataAndType(path, "image/*");
getActivity().startActivity(intent);
none of the above worked for me,
after a few hours debugging I found out that the problem is in createImageFile(), specifically absolute path vs relative path
I assume that you guys are using the official Android guide for taking photo. https://developer.android.com/training/camera/photobasics
private static File createImageFile(Context context) throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = context.getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
Take note of the storageDir, this is the location where the file will be created. So in order to get the absolute path of this file, I simply use image.getAbsolutePath(), this path will be used in onActivityResult if you need the Bitmap image after taking photo
below is the file_path.xml, simply use . so that it uses the absolute path
<paths>
<external-path
name="my_images"
path="." />
</paths>
and if you need the bitmap after taking photo
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Bitmap bmp = null;
try {
bmp = BitmapFactory.decodeFile(mCurrentPhotoPath);
} catch (Exception e) {
e.printStackTrace();
}
}
If nothing helps and you are getting the error
failed to find configured root that contains /data/data/...
then try changing some line like:
File directory = thisActivity.getDir("images", Context.MODE_PRIVATE);
to:
File directory = new File(thisActivity.getFilesDir(), "images");
and in the xml file:
<files-path name="files" path="." />
which is weird, since the folder I access is /images.
The problem might not just be the path xml.
Following is my fix:
Looking into the root course in android.support.v4.content.FileProvider$SimplePathStrategy.getUriForFile():
public File getFileForUri(Uri uri) {
String path = uri.getEncodedPath();
final int splitIndex = path.indexOf('/', 1);
final String tag = Uri.decode(path.substring(1, splitIndex));
path = Uri.decode(path.substring(splitIndex + 1));
final File root = mRoots.get(tag); // mRoots is parsed from path xml
if (root == null) {
throw new IllegalArgumentException("Unable to find configured root for " + uri);
}
// ...
}
This means mRoots should contains the tag of requested uri. So I write some code to print mRoots and tag of uri, and then easily find the tags do not match.
It comes out that setting provider authority as ${applicationID}.provider is a stupid idea! This authority is so common that might be used by other providers, which will mess up the path config!
I was getting this error Failed to find configured root that contains...
The following work around resolves my issue
res/xml/file_paths.xml
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="media" path="." />
</paths>
AndroidManifest.xml
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="[PACKAGE_NAME]"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths">
</meta-data>
</provider>
ActivityClass.java
void shareImage() {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM, FileProvider.getUriForFile(this,"com.slappstudio.pencilsketchphotomaker", selectedFilePath));
startActivity(Intent.createChooser(intent,getString(R.string.string_share_with)));
}
Android official document says file_paths.xml should have:
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images"
path="Android/data/com.example.package.name/files/Pictures" />
</paths>
But to make it work in the latest android there should be a "/" at the end of the path, like this:
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images"
path="Android/data/com.example.package.name/files/Pictures/" />
</paths>
The following change in xml file_paths file worked for me.
<external-files-path name="my_images" path="Pictures"/>
<external-files-path name="my_movies" path="Movies"/>
My Problem Was Wrong File Name:
I Create file_paths.xml under res/xml while resource was set to provider_paths.xml in Manifest:
<provider
android:authorities="ir.aghigh.radio.fileprovider"
android:name="android.support.v4.content.FileProvider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
I changed provider_paths to file_paths and problem Solved.
If your file path is like /storage/emulated/0/"yourfile"
you just need modify your FileProvider xml
<paths>
<external-path name="external" path="." />
</paths>
then call this function when you need share file
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri fileUri = FileProvider.getUriForFile(getContext(),
"com.example.myapp.fileprovider",
file);
sharingIntent.setType("*/*"); // any flie type
sharingIntent.putExtra(Intent.EXTRA_STREAM, fileUri);
startActivity(Intent.createChooser(sharingIntent, "Share file"));
it works on android M ~ Pie
The Answer from #CommonsWare is great.
But in my case, I had to add multiple paths.
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path name="external_files" path="." />
<files-path name="external_files" path="." />
</paths>
I see that at least you're not providing the same path as others in file_paths.xml.
So please make sure you provide the exact the same package name or path in 3 places including:
android:authorities attribute in manifest
path attribute in file_paths.xml
authority argument when calling FileProvider.getUriForFile().
For Xamarin.Android users
This could also be the result of not updating your support packages when targeting Android 7.1, 8.0+. Update them to v25.4.0.2+ and this particular error might go away(giving you´ve configured your file_path file correctly as others stated).
Giving context: I switched to targeting Oreo from Nougat in a
Xamarin.Forms app and taking a picture with the Xam.Plugin.Media
started failing with the above error message, so updating the packages
did the trick for me ok.
I noticed that the policy or behaviour regarding the path.xml file changed between Support Library 26 and 27. For capturing a picture from the camera, I saw the following changes:
With 26, I had to use <external-path> and the full path given in the path argument.
With 27, I had to use <external-files-path> and only the subfolder in the path argument.
So what specifically worked for me with Support Library 27 as the path.xml file was
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-files-path name="camera_image" path="Pictures/"/>
</paths>

I want to add code using OC mode in all module file

I want to add code in all controller file of module in admin side using OCMOD.
My code is:
<file path="admin/controller/module/*.php">
<operation>
<search trim="true"><![CDATA[
public function index() {
]]></search>
<add position="after" trim="true"><![CDATA[
$this->document->addScript('catalog/view/javascript/xxxx.js');
]]></add>
</operation> </file>
But it doesn't work.
I have try your code. It is working fine. please try following.
You have to create ocmod xml file with ".ocmod.xml" extension, then you can upload that file using "Extension Installer" from admin panel of opencart.
You have to clear and refresh the modification cache to update the system and make the extension work. You can clear and refresh by top right buttons on Extension > Modification page in admin panel.
Example OCMOD file with your code: (File name: test.ocmod.xml)
<?xml version="1.0" encoding="utf-8"?>
<modification>
<code>mycode001</code>
<name>Modification Default</name>
<version>1.0</version>
<author>OpenCart</author>
<link>http://www.opencart.com</link>
<file path="admin/controller/module/*.php">

MSBuild: Permanently Change PropertyGroup Property of a Project

I was hoping to find a way to set a value in my csproj file during my build to a value. Is there a task in MSBuild that I can use to set a property permanently to a value? In the example below, can I set CustomValue = Yes permanently?
<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<PropertyGroup>
.....
<CustomValue>XXXX</CustomValue
<FileAlignment>512</FileAlignment>
<ProjectTypeGuids></ProjectTypeGuids>
<SccProjectName>SAK</SccProjectName>
<SccLocalPath>SAK</SccLocalPath>
<SccAuxPath>SAK</SccAuxPath>
<SccProvider>SAK</SccProvider>
</PropertyGroup>
You can use the XmlPoke task to do that. It seems a little odd to be altering projects this way though. Alternatively, you can set up a tiny import file,
<!-- in your main project file, right below the PropertyGroup -->
<Import
Condition="Exists('Custom.props')"
Project="Custom.props"
/>
Then dynamically create this property file, as,
<?xml version="1.0" encoding="utf-8"?>
<Project
xmlns="http://schemas.microsoft.com/developer/msbuild/2003"
ToolsVersion="4.0">
<PropertyGroup>
<CustomValue>True</CustomValue>
</PropertyGroup>
</Project>
You can either use XmlPoke on just this .props file, or use WriteLinesToFile to create the entire file. This secondary file wouldn't need to be checked into source control, the condition on the import makes the project functional when the file doesn't exist.
The XmlPoke task would look like this,
<XmlPoke
XmlInputPath="./Custom.props"
Namespaces="<Namespace Prefix='x'
Uri='http://schemas.microsoft.com/developer/msbuild/2003'/>"
Query="//x:PropertyGroup/x:CustomValue/#Value"
Value="True"

IISExpress Log File Location

IISExpress writes log and configuration data to pre-determined location out of the box.
The directory is an "IISExpress" directory stored in a user's Documents directory.
In the directory is stored the following folders files underneath.
Config
Logs
TraceLogFiles
The location of my home directory is on a network share, determined by group policy
Currently we are encountering scenarios where visual studio locks up when stopping debugging Silverlight applications using IIS Express.
I was looking to change the location for the log & configuration data for IISExpress to see if this fixes the problem of visual studio locking up. Is it possible to change the default location of log & config files ?
1 . By default applicationhost.config file defines following two log file locations. Here IIS_USER_HOME would be expanded as %userprofile%\documents\IISExpress\.
<siteDefaults>
<logFile logFormat="W3C" directory="%IIS_USER_HOME%\Logs" />
<traceFailedRequestsLogging directory="%IIS_USER_HOME%\TraceLogFiles" enabled="true" />
</siteDefaults>
You can update above directory paths to change the log file locations.
2 . If you are running IIS Express from command line, you can use '/config' switch to provide configuration file of your choice. Following link may help you http://learn.iis.net/page.aspx/870/running-iis-express-from-the-command-line/
http://www.iis.net/configreference/system.applicationhost/sites/sitedefaults
<configuration>
<system.applicationHost>
<sites>
<siteDefaults>
<logFile
