WndProc e FindWindow

[crino]

Hi,
it's normal that findwindow() doesn't returns the same handler of
MessageWindow in CF??
if no...
why MessageWindow doesn't match with FindWindow??

thanks in advance

What do you mean? Can you provide code that shows the descrepancy?

MessageWindow is not a WinProc of your From. It's a separate "helper" window
that's created to provide some means of comminication between the native and
managed worlds. If you want to get the WinProc in v1 of CF you can use the
ApplicationEx from SDF:

or NativeWindows in CV v2:

in my main form i written:
internal class MsgWindow: MessageWindow
{
public MsgWindow()
{
}
protected override void WndProc(ref Message m)
{
switch(m.Msg)
{
case 5000:
break;
}
base.WndProc (ref m);
}
}
in form constructor:
msg = new MsgWindow();
IntPtr hwndInMain = msg.Hwnd;

in an other app i'm tring to send a message to the main application,
so:
IntPtr hwndOfMain = FindWindow(null, "MyApp");
if (hwndOfMain != IntPtr.Zero)
{
int ret = SendMessage(hwndOfMain, 5000, 1, 0);
}

why hwndOfMain is different of hwndInMain ??
