Fellow botters, what am I doing wrong here?

I'm using PostMessage to send keys to third party software.. This code below works fine for Uppercase characters but when I send Lowercase it seems to send 3 of each character sent.

This is a cut down example of sending the "c" character. I know its not the software because it does the same in notepad.

What am i doing wrong here?

[DllImport("user32.dll")]
[return:MarshalAs(UnmanagedType.Bool)]
staticextern bool PostMessage(IntPtr hWnd,uint msg,IntPtr wParam,IntPtr lParam);

constint WM_KEYDOWN =0x100;
constint WM_KEYUP =0x101;
constInt32 WM_CHAR =0x0102;

IntPtr val =newIntPtr((Int32)'c');
PostMessage(WindowHandle, WM_KEYDOWN, (IntPtr)(val -0x020),newIntPtr(0));
PostMessage(WindowHandle, WM_CHAR, (IntPtr)val,newIntPtr(0));
PostMessage(WindowHandle, WM_KEYUP, (IntPtr)(val -0x020),newIntPtr(0));

just use autoit if this is all you're wanting. much less code. use the help file in the editor.

Ye i did look at that, you can get a lib for c# as well but I wanted to keep it all native. Still though, another option if I can't figure this out

Spy++ output is

<000001> 000204B6 P WM_KEYDOWN nVirtKey:'C' cRepeat:1 ScanCode:2E fExtended:0 fAltDown:0 fRepeat:0 fUp:0
<000002> 000204B6 P WM_CHAR chCharCode:'99' (99) cRepeat:1 ScanCode:2E fExtended:0 fAltDown:0 fRepeat:0 fUp:0
<000003> 000204B6 P WM_KEYUP nVirtKey:'C' cRepeat:1 ScanCode:2E fExtended:0 fAltDown:0 fRepeat:1 fUp:1

Did you figure out what you are doing wrong?
