I'm trying to run 'CreateProcess' in c, with a custom string that I build.
When I'm using a simple string like:
TCHAR command[]= _T("MyApp.exe -OPTION1 -OPTION2")
Everything seems to work fine.
But as I try to build a custom string (with getting MyApp OPTIONS from an other source), and concatenate the options to the string "MyApp.exe" using sprintf_s or swprintf_s the string I get is the same, but the process gives me an exit code of (2) - meaning (FILE_NOT_FOUND).
I'll be grateful for any help..
I've managed to find the answer,
If anyone had the same problem, you need to open your project's properties, and enter to:
Configuration Properties-> General
then set 'Chracter Set' to Not Set

With version 3.02 of NSIS came the addition of the WriteRegMultiStr function. When the function is called in my script the script throws an error:
Usage: WriteRegMultiStr /REGEDIT5 rootkey subkey entry_name hex_string_like_660000000000
root_key=(HKCR[32|64]|HKLM[32|64]|HKCU[32|64]|HKU|HKCC|HKDD|HKPD|SHCTX)
The call itself looks like this:
WriteRegMultiStr /REGEDIT5 HKLM "System\CurrentControlSet\Services\SomeService" "DependsOnService" "service1 service2"
Since there is no documentation on this specific function which was added later on, long after WriteRegStr and WriteRegDWORD were available, I have to wonder - how does one use it?
So far with respect to entering REG_MULTI_SZ values I only found the directive to use a registry-NSIS -plugin. Yet the function exists, so how can it be used?
Addendum:
Encoding the string to hex and passing it with ot without quotation marks yields no desirable result either.
I was actually able to find an answer after digging through the depths of the internet. Since I don't think this has been answered on StackOverflow I will leave a response here, in case anyone wants to use this function.
The structure of the command as described in the opening post is basically correct, but the value must be encoded precisely. My command looks like this:
WriteRegMultiStr /REGEDIT5 HKLM "System\CurrentControlSet\Services\SomeService" "DependsOnService" 54,00,63,00,70,00,69,00,70,00,00,00,41,00,66,00,64
For anyone intending to test this string, this is
Tcpip
Afd
encoded in hexadecimal regedit format. Precisely this is Regedit Version 5.0 format, as opposed to REGEDIT4 format. A conversion editor can be used to achieve this, I used OTConvertIt.
The script should then compile, assuming you run NSIS version 3.02 or higher.
As you found out, the value data must be in the exact same format as .reg files from Windows 2000+.
The reason this instruction works this way is because it is actually the same as WriteRegBin under the hood and very little code was added to support this new functionality.
In the future you might be able to drop the /REGEDIT5 switch and give it plain strings but support for that has not been added yet.
The Registry plug-in does allow you to write these strings in a sane manner.
I have a handheld device running WM6.5 and trying to put together an application that should prompt the user for some information (login, password) and save it to a file for later use.
Have tried app.config files but unfortunately it requires System::Configuration, I can add the DLL but can't get the code to run, it requires CRL or something like that which I can't configure this being a mobile app - the required option is missing from the project/solution configuration section.
I am using Visual Studio 2008 C++
What's the best way to make this happen? Precisely, 1) write a string somewhere and 2) read it back later on.
TIA
Later edit:
I have tried using a binary file, like this
// write to config file
std::string s="helloworldhelloworldhelloworld";
ofstream ofile("test.txt",ios::binary);
ofile.write((char*)s.c_str(),strlen(s.c_str()));
ofile.close();
And then I have tried reading it back like this
// read config file
char read_str[60];
ifstream inf("test.txt",ios::binary);
inf.read(read_str,60);
inf.close();
LPCTSTR application_settings = CA2W(read_str);
What happens is it adds some garbage at the end of the string, if the string is longer less garbage, otherwise more.
Is there a way to sort out this conversion issue?
Turns out, project was using Unicode and had to use wifstream and wofstream to be able to properly read the strings, rather than attempt to convert them from ANSI to unicode.
This should be a reminder for me to stay away from strong typed languages in the future. Too bad there's no other significant choice for Windows Mobile. Spent a bunch of hours on this, I could have used that time for something else.
When doing
java -cp C:\Tools\Libraries\antlr4-csharp-complete.jar org.antlr.v4.Tool Hello.g4
I get the following files:
HelloBaseListener.cs
Hello.tokens
HelloListener.cs
HelloParser.cs
HelloLexer.tokens
HelloLexer.java
My question is about the last file. Why is it .java instead of .cs?
I'm using antlr4-csharp-4.0.1-SNAPSHOT-complete.jar
Grammar is:
grammar Hello; // Define a grammar called Hello
options
{
language=CSharp_v4_0;
}
r : 'hello' ID ; // match keyword hello followed by an identifier
ID : [a-z]+ ; // match lower-case identifiers
WS : [ \t\r\n]+ -> skip ; // skip spaces, tabs, newlines, \r (Windows)
Hello Sam! I only have visual studio express so I can't install the extension. This is the code that I'm using but it is still generating the HelloLexer.java.
AntlrClassGenerationTaskInternal a = new AntlrClassGenerationTaskInternal();
List<String> files = new List<string>();
files.Add(#"C:\Tools\Grammars\Hello.g4");
a.JavaVendor = "JavaSoft";
a.ToolPath = #"C:\Tools\Libraries\antlr4-csharp-complete.jar";
a.JavaInstallation = "Java Development Kit";
a.SourceCodeFiles = files;
a.OutputPath = #"C:\Tools\Grammars\CSharp\";
a.Execute();
By the way, visual studio complained because it was not able to find Antlr4ClassGenerationTask.IsFatalException(ex)
I appreciate your help on this.
Regards,
Omar.
I think it's a bug, I had got the same problem, but there is a solution.
1) If you want you can remove
options
{
language=CSharp_v4_0;
}
I think is ignored by the code generator
2) create a BAT file with the follow code
#echo OFF
IF "%CLASSPATH%" == "" (SET CLASSPATH=.;.\antlr4-csharp-4.0.1-SNAPSHOT-complete.jar;%CLASSPATH%)
java org.antlr.v4.Tool %* -Dlanguage=CSharp_v4_5
put antlr4-csharp-4.0.1-SNAPSHOT-complete.jar in the same path, now you can use this file to comile. To resolve the issue the magic command line argument is "-Dlanguage=CSharp_v4_5" or the version of C# you are using.
The generated files now have inside the Lexer.cs
Edit 11/20/13: Updated instructions are now available on the project wiki
https://github.com/sharwell/antlr4cs/wiki/Installation
Here are a few messages I sent over the past few months related to this issue. If you don't want to install the Visual Studio extension described below, you'll need to use the source code of Antlr4ClassGenerationTaskInternal.cs to determine a set of command line options that will work.
Also, you can remove the language=CSharp_v4_0; option because it's passed on the command line now.
The C# target wasn't designed for command line usage. You will need to integrate the code generation into your project file according to the instructions on the following page, and the parsers will be generated automatically when you build your project.
https://github.com/sharwell/antlr4cs
You do need to include the .g4 file in your project and configure a few properties of the file. If you install the following extension before adding the grammar to your project, all the other options will be configured for you automatically.
ANTLR Language Support for Visual Studio 2010-
2012
If you already have the .g4 file in your project, and want to still use the extension to automatically configure the proper settings, you can do the following:
Install the extension.
Click the project in Solution Explorer and enable Show All Files (button on the Solution Explorer toolbar). This step greatly simplifies step 4.
Right click the .g4 file in the project, and select Exclude From Project.
Right click the .g4 file again and select Include In Project.
(Optional) You can disable Show All Files when you no longer need it.
I am trying to get application data folder location under Linux using Qt's storageLocation function:
QDesktopServices::storageLocation(QDesktopServices::DataLocation)
But this function returns path with two slashes at the end:
/home/user/.local/share/data//
Two slashes at the end of path looks very strange for me. Is this normal? Or this is bug in Qt?
My Linux is Ubuntu.
Qt version is 4.8.1.
This is a bug in Qt (see bug report). However, it happens only if you didn't set your app's name and organization name. You should set them using QApplication::setApplicationName and QApplication::setOrganizationName.
The chop solution you've accepted earlier is bad for two reasons. The first, if this bug is fixed, your code could be broken. Who knows how many slashed will be here in the next version (maybe 0). I'd suggest to use the following to remove double slash:
QString s = QDesktopServices::storageLocation(QDesktopServices::DataLocation);
s = QDir(s).absolutePath();
But it's more important that the /home/user/.local/share/data/ location is still invalid. You need to set application and organization names if you want to get proper location. Simple removing trailing slash doesn't fix anything, it's just a dirty hack.
I know it's an old question but QDesktopService::dataLocation have the following structure <user data location>/<application name>/.
Under linux, the user data location is $HOME/.local/share/data/.
The application name is set via the QCoreApplication::setApplicationName() method, I guess you do not set it, which explains why you have two trailing slashes.
No its not only you its same on here. you just need to chop the last character
QString s = QDesktopServices::storageLocation(QDesktopServices::DataLocation);
s.chop(1);
I just tried to use JCurses from within Groovy, but I always get the following exception:
Caused by: java.lang.NullPointerException at
jcurses.system.Toolkit.getLibraryPath(Toolkit.java:97) at
jcurses.system.Toolkit.<clinit>(Toolkit.java:37)
Toolkit.java:37 :
String url = ClassLoader.getSystemClassLoader()\
.getResource("jcurses/system/Toolkit.class").toString();
Google told me that it could have to do with spaces within the classpath (windows), but moving the library and even using the classes instead of the .jar file was not successful.
It seems to be possible - pleac for groovy references JCurses: http://pleac.sourceforge.net/pleac_groovy/userinterfaces.html
Another way to clear the screen from within a Groovy shell script would also solve my problem. :-)
As jline is bundled with Groovy, can't you use the class jline.ANSIBuffer.ANSICodes (as is shows in the page you linked to)
print jline.ANSIBuffer.ANSICodes.clrscr()
You might also need to do:
print jline.ANSIBuffer.ANSICodes.gotoxy( 1, 1 )
If you want the cursor to go back to the top of the screen
To draw coloured text, you can do:
println new jline.ANSIBuffer().append( 'Some ' )
.red( 'Red' )
.append( ' text' )
.toString()
The root problem is most likely that jcurses.jar was not being found on your classpath, causing ClassLoader.getSystemClassLoader().getResource("jcurses/system/Toolkit.class") to return null.
There's a related problem you can run into if it can't find the C library containing the native code (libjcurses.so or libjcurses64.so on linux). It expects the C libary to be in the same folder where it found jcurses.jar. If it's not there, you'll get:
java.lang.RuntimeException: couldn't find jcurses library
found another trivial way to clear the screen :-)
