hi all.
I have some problems in programming rich text box i succeeded to draw an image inside text box as emoticons by using dataformats and clipboard but the problems are:

1- the emoticons entered inside the rtb unanimated even if it is animated how can i implement that emoticons animated ?????????????

2- when the emoticons entered the richtext box if you point with your mouse pointer on it in rtb you can resize it how can i make it fixed ?????????

3- when i press my send button to send emoticons to the other user in chat the previous emoticons in my rich text box disappears and even the previous one transfered disappears in the private chat of the other user.
how can i make the emoticons don't disappears and make my rtb contains all the emoticons ?

Any help with this please .
i used the following code.

<br />
<br />
Bitmap myemot = new Bitmap(dialog.filename);<br />
ClipBoard.setDataObject(myemot);<br />
DataFormats.Format chm = DataFormats.GetFormat(DataFormats.Bitmap);<br />
rtb.text +=myusername + " \r\n";<br />
if(rtb.canpaste(chm))<br />
{<br />
rtb.paste(chm);<br />
}<br />

The Above Code makes the bitmap enter the rtb but with the previous problems any help with that please

is there a way to give basic windows controls a better look, like a skin ect.. or do you have to create a custom control?
if I have to make a custom control anyone know of a good sample?
thanks

There are heaps of samples on this very site. I think XP has some options for controls, but overall, if you want to change how they look, you need to draw them yourself.

Splash Screen Architecture

Hello all,
After reading almost all tutorials on splash screen for C# I'm quite confused which aproach to take. So I want to ask you what would be the best way. Personally, what I've been thinking is doing something like this:
1. In Main() start the splash thread
2. Run the Main form thread
3. main form thread sends signals to the splash thread about the progress
4. main form sends a signal to the splash thread that it has finished and the splash thread closes itself

The thing is that I've done some threading recently but I haven't actually encountered how to call object methods on different threads. Another thing which I'm not sure about is, should the function which is to be called for the start point of the thread call Application.Run(SplashThread) for the splash thread and Application.Run(MainForm) ? Any advice is greatly appreciated.

I don't see the need for another thread. Your main thread can just open a window which shows the splash screen, then close it using either a timer, or at a specific point during initialisation ( i.e. just before the main app is ready to show itself ).

But if I show the splash using Application.Run(Splash); the function will return when the splash is closed, am I right? If it's that way, then I'm in a deadlock. That's why I resort the threads.

Why would you do this ? I'm talking about a modeless form being shown by your application, during startup. Sure, you can use a thread, it just seems like overkill to me.

Because using the same message pump for both the splash screen and the main application window might cause the splash screen to freeze if there is some heavy duty initialization involved.

How does a splash screen 'freeze' ? I guess if you move something in front of it ?

Yes. And if you intend to show some dynamic text in the splash screen window.

You could do all your initializing in the Main() function.

Something like as follows:

static void Main()
{
// Create splash
fclsSpash splash = new fclsSplash();
splash.Show();

// Create main form
fclsMain main = new fclsMain();

// Initialize this
splash.SetMessage("Initializing this.");
main.InitializeThis();

// Initialize that
splash.SetMessage("Initializing that.");
main.InitializeThat();

// Close splash
splash.Dispose();

// Show main
main.Show();

// Start application
Application.Run();
}

Hello,

I did solve my problem with the initial structure. So this is what I'm doing in Main():
1. Create Splash thread
2. Start Splash thread
3. Create Main Window Thread
4. Start Main Window Thread
5. Hide Main Window
The thing which I'm working now is to implement an event which will signalize the splash screen that main is ready and it should close itself and Main form should appear.

oh - and if you want to check if MDI is active, just compare:

if (mdi == this.ActiveMdiChild)
// mdi is active
else
// mdi is inactive

Maybe it is printing outside the margins of the page.

Try: e.Graphics.DrawString(txtText.Text, fnt, Brushes.Black, e.MarginBounds.Location);

No joy. Tried it and get the same behavior. Thank you for the suggestion.

In working on a small C#.net program that starts another program via rundll32. This program performs an operation and then opens a IE page showing some results. I would like to be able to close this IE process after the WaitForExit() call.

Process proc = new Process();<br />
ProcessStartInfo processInfo = new ProcessStartInfo("rundll32.exe");<br />
processInfo.Arguments = Config.DLL_ARGUMENTS;<br />
proc.StartInfo = processInfo;<br />
proc.Start();<br />
proc.WaitForExit();<br />
//how to close the IE window that was started by the rundll32 call.

I know how to get a list of processes running, but how do I know which was the IE started by my other proc. call??

Thanks for any help!
