I made a dll for Windows Shell Extension integration, following this tutorial http://blogs.msdn.com/b/codefx/archive/2010/09/14/writing-windows-shell-extension-with-net-framework-4-c-vb-net-part-1.aspx[^]
Now, I added a Windows form in that dll, I'm doing the following:
void OnVerbDisplayFileName(IntPtr hWnd)
{
ShowSelectedFiles form = new ShowSelectedFiles();
form.Show(selectedFiles);
}
Everything works fine, just the Forms icon is not shown in task bar and I can't find the process that runs my form.
Any tip on how to solve this problem? Maybe by starting a new process and then showing the form?
Thanks
Try using the Form.Show Method (IWin32Window) method so that you can specify the owner window.
See http://ryanfarley.com/blog/archive/2004/03/23/465.aspx for how to specify the owner window from an hWnd.
Also make sure that the form's ShowInTaskBar property is true.
The only way to solve this is to create another process.
void OnVerbDisplayFileName(IntPtr hWnd)
{
string file = (new System.Uri(Assembly.GetExecutingAssembly().CodeBase)).AbsolutePath;
string executableName = file.Substring(0, file.LastIndexOf("/"));
executableName += "/MyApp.exe";
Process gui = new Process();
gui.StartInfo.FileName = executableName;
gui.StartInfo.Arguments = selectedFiles.JoinFileNames(" ");
gui.Start();
}
Cheers!

I am trying to use the SFAutoComplete control from SyncFusion in a Xamarin iPad app. (only iPad).
I am not able to get any sort of change event to fire.
What I've tried:
If you download SyncFusion and install it, it comes with a "SampleBrowser" app that has samples for all the controls in the suite.
If you open that SampleBrowser in visual studio and open the AutoComplete_Tablet.cs file after line 97, I've added this code:
countryAutoComplete.ValueChanged += (sender, args) =>
{
suggestionModeLabel.Text = "IT WORKED!";
};
But it never fires.
I've tried to use several different events from the list of events this control has (partial list from screenshot):
None of them seem to fire (I haven't tried ALL of them).
What do I need to do to get one of these events to fire? What am I missing?
Thanks for using Syncfusion Controls.
Delegate property can be used to hook the SFAutoComplete's events as per in the following code example,
Declaration code for Delegate property
SFAutoComplete autocomplete = new SFAutoComplete();
autocomplete.Delegate = new SFAutoCompleteDelegate();
The way to hook the events in SFAutoComplete
public class SFAutoCompleteDelegate : AutoCompleteDelegate
{
public override void DidTextChange(SFAutoComplete SFAutoComplete, string value)
{
//It fired while changing the text in AutoComplete
}
public override void DidSelectionChange(SFAutoComplete SFAutoComplete, string value)
{
//It fired while changing the suggestion from suggestion box.
}
}
We have created a sample for achieving your requirement. Please download the same from the following link

I have a MDI application in which there are some reports and the Reports are printed and print preview in way that the was given by the MFC Printing Architecture.
But now the scenario changed and the Reports need to be formatted as a HTML File and need to be shown in the different perspective, based on a preference. I have choose a solution based on the Application architecture as there are many Document/View in my CWinApp. Created all Doc/view Templates there and the new Doc/View will be created based on the setting, once the application starts.
class CMyWinApp: public CWinApp
{
public:
virtual BOOL InitInstance();
protected:
}
BOOL CMyWinApp::InitInstance()
{
// Lot of Code Here
CreateDocumentTemplates();
}
void CMyWinApp::CreateDocumentTemplates()
{
// Some Other Doc/Templates are here
if(m_bNewView) // Based on the Setting I am creating the new View and Old Doc
{
pDocTemplate = new CMultiDocTemplate(
IDR_REPORTS,
RUNTIME_CLASS(CMyDoc),
RUNTIME_CLASS(CMyFrame), // custom MDI child frame
RUNTIME_CLASS(CMyNewView));
pDocTemplate->SetContainerInfo(IDR_TYPE_CNTR_IP);
AddDocTemplate(pDocTemplate);
}
else // This is a Old View and Doc
{
pDocTemplate = new CMultiDocTemplate(
IDR_REPORTS,
RUNTIME_CLASS(CMyDoc),
RUNTIME_CLASS(CMyFrame), // custom MDI child frame
RUNTIME_CLASS(CMyView));
pDocTemplate->SetContainerInfo(IDR_TYPE_CNTR_IP);
AddDocTemplate(pDocTemplate);
}
}
Now the scenario is, this preference can be set anytime and the further Reports need to be shown in a appropriate context.
How this can be achieved on the run time? Please help me :(
In your app class, create and save both CMultiDocTemplate pointers from your CreateDocumentTemplates function and use these to create your documents on demand(e.g override ID_FILE_NEW/ID_FILE_OPEN or similar). Look at OpenDocumentFile of CDocTemplate.
Then in your OnFileNew function or similar you can use something like this:
if(m_bNewView) {
m_pNewDocTemplate->OpenDocumentFile(...);
}
else {
m_pOldDocTemplate->OpenDocumentFile(...);
}
I would integrate CMyNewView in CMyView, if you need to switch the view dynamically. If you work with at least Visuals Studio 2008 (incl. feature pack), I recommend deriving your view class from CTabView to switch the view of the document using a handy tab next to the horizontal scrollbar of the child window.
I'm using Visual Studio 2012 Coded UI tests for a web application. I have a test for logging into the app which starts the browser, locates the login dialogue, enters credentials, and then clicks ok. I have an assertion which checks for the correct url after the login. This test appears to function correctly. My problem is that it closes the browser after the test runs. I need to keep the browser open, so I can run the next test in my sequence. How do I do this?
At the moment, I don't have anything in my [TestCleanup()] section. I'm assuming that what I'm looking for goes here, but so far I haven't had a lot of luck figuring out what that is supposed to be.
I don't have the original source where I found this solution :(
You can have a method like the one showed below. This method needs to be called in TestSetup. Also declare a class level variable _browserWindow of the tyep BrowserWindow
private void SetBrowser()
{
if(_browserWindow == null)
{
BrowserWindow.CurrentBrowser = "ie";
_browserWindow = BrowserWindow.Launch("http://www.google.com");
_browserWindow.CloseOnPlaybackCleanup = false;
_browserWindow.Maximized = !_browserWindow.Maximized;
}
else
{
BrowserWindow.CurrentBrowser = "ie";
_browserWindow = BrowserWindow.Locate("Google");
_browserWindow.Maximized = !_browserWindow.Maximized;
}
}
Ok, so what I needed to have happen was the launch and login before each test. I thought what I wanted was to run the browser and login test first, and then each additional test. After reading more, I've decided what I actually wanted was to run this logic as initialization code for each test. I've done that by adding this code to the default [TestInitialize()] generated when I started the coded ui project in Visual Studio 2012.
I have found the following method to work for my data driven coded UI test in Visual Studio 2015.
You will want to use [ClassInitialize] and get your browser open and direct it according to where your [TestMethod] begins.
Use [ClassCleanup] to release the resources after all the methods in the test class have been executed.
You can redirect test methods different after the class has been initialized by using the [TestInitialize] and clean-up test using the [TestCleanup]. Be careful with those though because they will occur for each test method and if it closes your browser instance your following test will fail.
private static BrowserWindow browserWindow = null;
[ClassInitialize]
public static void ClassInitialize(TestContext context)
{
Playback.Initialize();
browserWindow = BrowserWindow.Launch(new Uri("http://198.238.204.79/"));
}
[ClassCleanup]
public static void TestCleanup()
{
browserWindow.Close();
Playback.Cleanup();
}
I have a test method which requires Internet Explorer to be opened and closed numerous times during the test. I have been creating a process like this:
Process process = Process.Start(...);
And closing it like this:
process.CloseMainWindow();
However, I have found that I can only call this method once, otherwise I get the error message, "Process has exited, so the requested information is not available".
Once I have closed the process, I would then re-launch Internet Explorer. e.g.
process = Process.Start(...);
But this didn't work. I also tried nulling the Process variable before calling the Process.Start() method, but this didn't work.
I also tried using process.Kill(), but this caused problems too.
What is the correct way to do this?
UPDATE: Code
Process Browser;
[TestInitialize]
public void TestSetup()
{
Browser = TestBase.LaunchBrowser();
...
Browser.WaitForInputIdle();
Browser.CloseMainWindow();
Browser = null
Browser = Process.Start("IExplore.exe", ...);
}
[TestMethod]
public void MyTest()
{
// do things
Browser.Kill();
Browser = Process.Start("IExplore", "www.adifferentwebpage");
}
[TestCleanup]
public void TestCleanup
{
Browser.Kill();
}
I suggest to create another process without reusing the same variable.
Encapsulate your code inside a using statement to properly close and dispose the process variable
using(Process process = new Process())
{
// do you stuff
process.Start(.....);
process.CloseMainWindow();
}
Also remember that calling CloseMainWindow doesn't gurantees that the process will close. It only sends a request to close to the main window of the process. If the application ask for user confirmation before quitting it can refuse to quit.
I found a solution, but it only applies to those who have access to the Coded UI test DLL's (which I believe comes with Visual Studio Ultimate and Premium).
Therefore I will change the tags on the question.
If you create a Coded UI test project, these DLL references will already be there, but this using reference is what you need:
using Microsoft.VisualStudio.TestTools.UITesting;
To create a browser window:
BrowserWindow browser = BrowserWindow.Launch(new System.Uri("www.whatever.com"));
To close:
Browser.Close();
This worked no matter how many times I needed to relaunch the browser. This API also includes a multitude of other handy features like the ability to delete cookies, change the URL of the current browser, resize the window etc.
Hi noticed some code in our application when I first started Java programming. I had noticed it created a dialog from a separate thread, but never batted an eye lid as it 'seemed to work'. I then wrapped this method up through my code to display dialogs.
This is as follows:
public class DialogModalVisibleThread
extends Thread {
private JDialog jDialog;
public DialogModalVisibleThread(JDialog dialog, String dialogName) {
this.setName("Set " + dialogName + " Visable");
jDialog = dialog;
}
#Override
public void run() {
jDialog.setVisible(true);
jDialog.requestFocus();
}
}
Usage:
WarnUserDifferenceDialog dialog = new WarnUserDifferenceDialog( _tableDifferenceCache.size() );
DialogModalVisibleThread dmvt = new DialogModalVisibleThread( dialog, "Warn User About Report Diffs");
dmvt.start();
Now, as far as I am now aware, you should never create or modify swing components from a separate thread. All updates must be carried out on the Event Dispatch Thread. Surely this applies to the above code?
EDT on WikiPedia
However, the above code has worked.
But lately, there have been countless repaint issues. For example, click on a JButton which then calls DialogModalVisibleThread to display a dialog. It caused buttons alongside the clicked button not to redraw properly.
The repaint problem is more frequent on my machine and not the other developers machine. The other developer has a laptop with his desktop extended onto a 21" monitor - the monitor being his main display. He is running Windows 7 with Java version 1.6.0_27.
I am running on a laptop with Windows 7 and Java version 1.6.0_24. I have 2 additional monitors with my desktop extended onto both.
In the meantime I am going to upgrade to Java 1.6 update 27.
I wondered if the above code could cause repaint problems or are there any other people out there with related paint issues?
Are there any easy ways to diagnose these problems?
Thanks
So, you're breaking a rule, having problems, and wondering if these problems could be cause by the fact that you broke the rule. The answer is Yes. Respect the rules!
To detect the violations, you might be interested by the following page: http://weblogs.java.net/blog/2006/02/16/debugging-swing-final-summary
The easiest way to check if your problems are being caused by breaking the rules is to fix them (You should fix them anyway :-)
Just use SwingWorker.invokeLater() from the thread you want to update to UI from to easily adhere to Swing's contract. Something like this should do the trick:
#Override
public void run() {
SwingUtilities.invokeLater(new Runnable() {
jDialog.setVisible(true);
jDialog.requestFocus();
}
});
}
EDIT: You should make the 'jDialog' variable final for this to work.
