OnKeyPress oddity
-
I am deriving a class from ComboBox. I override OnKeyPress. But OnKeyPress never gets called! Anyone knows whether there is anything special I need to be doing? Nish

Well It's not an MC++ issue here. The same thing happens when I use C# :-( Nish

Ensure that IsInputKey/Char returns true for that key; if it returns false you won't get the OnKey* events. James Simplicity Rules!

I did this :-
protected override bool IsInputKey(System.Windows.Forms.Keys keyData)
{
base.IsInputKey(keyData);
return true;
}But still OnKeyPress never gets called! Nish

I overrode WndProc and found that the WM_KEYDOWN message is not being received :-(
protected override void WndProc(ref System.Windows.Forms.Message m)
{
base.WndProc(ref m);
if(m.Msg == 0x0100)
Text = "Hello World";
}Nish p.s. In an MC++ program I can #include windows.h to get the defines for various messages, in a C# program how do I get the defines for messages. Above I have hardcoded 0x0100 [WM_KEYDOWN]

Find in Files for WM_KEYDOWN ;P There are a couple programs out there which will let you get the constants but I find it much easier to just do a Find in Files. James Simplicity Rules!

Incidentally there was a discussion about this in one of my articles Link Don't use WndProc, use PreProcessMessage.

How your article works. I see that OnKeyPress is getting called. :) Ofcourse highlighting text by mouse doesnot work in your combo box. :(
