Hello,
I don't mean to double post, however I was just wondering if it is because I
am not subclassing my child window that the following program doesn't work?
Here is the problem:
I realized that the WM_KEYDOWN handler did not pick up my keystrokes on my
child window.
I have a WM_KEYDOWN handler in my main window, and when I press say F1 key,
I can trap it with a break point, but when I am in my second window, which is
a 2nd WindProc, I cannot trap the WM_KEYDOWN messages.
here is the basic code:
===================================WndProc.CPP
LRESULT CALLBACK WndProc(HWND hwnd, UINT message,
WPARAM wParam, LPARAM lParam)
{
...other code...
switch(message)
{
case WM_KEYDOWN:
switch(wParam) //**********Break point recognized at debug time
{
case VK_F2:
ShowWindow(hdCW1,SW_HIDE);
break;
}
return 0;
case WM_COMMAND:
if (LOWORD(wParam) == WindowButtons[1].MW_btC_ID) //If Button #1
{
hdCW1 = CreateWindow( //Create Child window #1
szCW1_ClassName,szCW1_Name,
WS_CHILD | WS_CAPTION | WS_SYSMENU,
150,50,400,300,hwnd,(HMENU)CW1_ID,
(HINSTANCE) GetWindowLong(hwnd,GWL_HINSTANCE),NULL);
ShowWindow(hdCW1,SW_SHOW); //Show child window #1
}
return 0;
...other code....
===============================================
And here is the code pertaining to the child window, pressing F1 key does
not get trapped by break point in this winproc?
===================================WndProc_CW1.CPP
LRESULT CALLBACK WndProc_CW1 (HWND hwnd, UINT message,
WPARAM wParam, LPARAM lParam)
{
...other code...
case WM_KEYDOWN:
switch (wParam) //Break point here! Break point NOT recognized at debug time
{
case 0: //Dummy case
break;
}
return 0;
...other code....
=================================================
Its like as if when I am in the child window and I press say F1 key, the
WM_KEYDOWN message is not sent, and even if I have a break point on the
following line:
switch (wParam)
debug doesn't stop on that line, it goes right through as if I had no break
point ????
So, again... can this be because I should use WM_KEYDOWN in a subclassing
proc?
If anyone has any ideas, please get back!
All help appreciated!
Thanks
