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?

Well

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

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

You mean in addition to overriding OnKeyPress I also need to override IsInputKey ???

I did this :-

protected override bool IsInputKey(System.Windows.Forms.Keys keyData)
{
    base.IsInputKey(keyData);
    return true;
}

But still OnKeyPress never gets called!

Use Anakrino. When you have anakrino you don't need to ask any quetions anywhere. Smile | :)

How do I use Anakrino in this situation, Rama? My problem is that a handler is not getting called in the derived class despite the fact that I have overridden it Frown | :-(

I overrode WndProc and found that the WM_KEYDOWN message is not being received Frown | :-(

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 Poke tongue | ;-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.

Don't use WndProc, use PreProcessMessage.

Ofcourse highlighting text by mouse doesnot work in your combo box. Frown | :(

Well I want to write a chat server. I know i gotta use threads for this
curelltly i do it like this:

TcpListener *pTcpListener;
pTcpListener = new TcpListener(80);
int i=0;
while (1)
{
pTcpListener->Start();
MyThread * Clients;
TcpClient * pTcpClient;
pTcpClient = pTcpListener->AcceptTcpClient();
Clients = new MyThread(true, "Client", pTcpClient); /*asicly start thread*/
}

Well the problem is i can't send to client unless he sends a request because I can't acces the Objects individually Frown | :(

what to do?
