Re: rs232-[B]

Thankyou William,

I will try this as soon as I can!

Quick question:

While I was trying stuff to solve the question in this post, I realized that
the WM_KEYDOWN handler did not pick up my keystrokes on my second 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 window?
===================================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 my 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 ????

If you have any ideas, please get back!

All help appreciated!

Thanks
