Prevent the ^ character from beeing entered in textbox.

How can I prevent the ^ character from being typed in a textbox? The problem seems to be that the character is not added before another keydown/keyup event.

For some other keys I used the following code to prevent them from being typed:

void textBox_KeyUp(object sender, KeyEventArgs e)
        {
            if ((Keyboard.Modifiers & ModifierKeys.Alt) == ModifierKeys.Alt)
            {
                if (e.PlatformKeyCode <= 12)
                    e.Handled = true;

                switch (e.PlatformKeyCode)
                {
                    case 226:
                        e.Handled = true;
                        break;
                }
            }
            else if ((Keyboard.Modifiers & ModifierKeys.Shift) == ModifierKeys.Shift)
            {
                switch (e.PlatformKeyCode)
                {
                    case 52:
                        e.Handled = true;
                        break;
                    case 186:
                        e.Handled = true;
                        break;
                }
            }
        }

However, this does not work for the ^ character.

Thanks for help!

Couple of things:
1) KeyUp is probably not a good place to disable keys, as KeyPress happens repeatedly before KeyUp occurs. Try handling KeyDown, KeyPress and KeyUp with Console.WriteLine in each to show the flow of events.
2) If you are going to use magic numbers then comment the damn things so the next poor sod stands a chance of understanding what you are doing:

// Disable '%' key
case 52:

is a lot more useful than

case 52:

By preference, use '%' instead of magic numbers, or constants with sensible names, or even "Keys."
3) Use KeyPress to disable your code:

private void textBox_KeyPress(object sender, KeyPressEventArgs e)
    {
    if (e.KeyChar == '^')
        {
        e.Handled = true;
        }
    }

Thanks for the replies guys. Sorry, but I forgot to mention that I work in Silverlight. I can't get to the KeyPress event. Only KeyDown and KeyUp.

Thanks again.

In that case you should probably post your question in the SilverLight Forum.

Hi everyone.

I'm having an error in my application that is confusing me.
The error is this one:

Could not find a part of the path "C:\CrkBusinessplatform\Aplicacao\Publico\sistemas\ccs\CRK.Monitores\sistemas\ccs\CRK.Monitores\monitor_arquivos\xslt\ACCS001.xslt"

Here are the facts: The correct path would be C:\CrkBusinessplatform\Aplicacao\Publico\sistemas\ccs\CRK.Monitores\xslt\ACCS001.xslt -> A part of the path is coming twice.
The archive ACCS001 is in this correct path.

The code line of the error is like this:
xslt.Load(Page.Request.PhysicalApplicationPath+"/monitor_arquivos/xslt/ACCS001.xslt");

I'm using .NET 1.1 on IIS 6.
The folder CRK.Monitores is a virtual directory in IIS. So the code should return the right path, right?

Oh, one more thing. The DLL of this page is the same here and there(I have checked it). And the error does not occur here.

Thanks in advance. Smile | :)

you seem to be mixing slashes and backslashes, Windows doesn't like that very much. Try using backslashes consistently.

Have you tried echoing Page.Request.PhysicalApplicationPath to confirm that what you think it outputs is what it actually outputs? To me, this looks like you're making a false assumption about the returned value.

Windows Form Freeze

Shyamraja1-Sep-09 1:11

Hi All,
I have created a custom video player in C#. This player has two forms.
1. The Video Player window ( running in primary (UI) thread )
2. The content playing window (running in a secondary thread)

Everything goes fine for nearly 5-6 hours, then the main video player window freeze.So i cannot access any of the buttons (stop, pause ,exit) in the player.

But the secondary thread keeps playing the files for even two days continuously ( which is the max i tested).

Things i have checked :
1. There is no memory issue, since i dispose the objects i create after playing each file ( few min videos) . I have checked the process in task manager, where status is running and memory usage as same as it is started.

2.I have used BeginInvoke from secondary thread to update the current playing file in the list box on the main video player window ( once the main window freeze, the update is not visible)

3. I have used a timer in the main video player window and tried refreshing form , calling Application
.DoEvent() for every few minutes , still it gets freeze up after 5-6 hours.

Why the UI window freeze up?
Is my architecture for the player is wrong?
(I need to do lots of processing in secondary thread for the images and videos to be played, but it is working fine)

Kindly give me your suggestions.

You can't display doc file into rich text box.It supports only rtf files or text files.
