Re: Clipboard.Clear() cause Excel Crashes at startup

I can clear the clipboard (with Clipboard.Clear) and successfully launch Excel 2007.
I suggest you check your facts.

Hi Luc Pattyn
Thanks for your info.
I tried 3 machines with vista ultimate sp2 / Excel 2007 all of them fail to launch.

if your app clears the clipboard and then fails to launch Excel, seems to me you have made some mistake.
Can't help lacking any additional information or code.

I found interesting scenario that crashes vs2005 c# IDE

public Form1()
{
InitializeComponent();
Clipboard.Clear(); // crashes vs IDE
}

I have not used the clipboard in C#, but in C++/Win32 you need to use the OpenClipboard() call to get access before changing anything. This is because the clipboard is a systemwide resource so you need to avoid conflicts with other processes.

no crash

Hi,
I have a RichTextBox and i want to do something when the user press on the RichTextBox with the combination of the keys : ctrl + 'C'.

I created this event :

private void m_richTextBox1_KeyUp(object sender, KeyEventArgs e)
{            
            if (e.Control && e.KeyData== Keys.C)
            {
                //Do Something
            }            
}

but when the user press on the keys it's recognize only the 'ctrl' key and not the char 'C'.
What is the problem and what should i do?

10X.

In either KeyDown or KeyUp

if (e.KeyCode == Keys.C && e.Modifiers == Keys.Control)
{
    //
}

Hi,

this is what I would try (not tested), and it doesn't use a PictureBox:

Bitmap bmIn=(Bitmap)Image.FromFile(sourceFile);
Bitmap bmOut=new Bitmap(4*bmIn.Width, bmIn.Height);
Graphics grOut=Graphics.FromImage(bmOut);
for(int i=0; i<4; i++) grOut.DrawImage(bmIn, bmIn.Width*i, 0);
bmOut.Save(destinationFile, ImageFormat.Jpeg);
grOut.Dispose();
bmIn.Dispose();
bmOut.Dispose();

hey... dont repost...

I think you cannot uninstall during system shutdown. Windows wait for ... seconds to shutdown all application, if the application cannot be end, then it will be killed.

You could set registry entries to remove the application on a windows startup.

you would run your app.
set the registry entries (runonce)
on restart the runonce would take effect and remove your app during windows startup.
