Hi
Does anyone know how to output messages to the debug window in the VC++ IDE.
Thanks in advance.

Look up the TRACE macro and the OutputDebugString function.

Hi all,
I am developing an On-Screen keyboard as part of my graduation project, I want the program to send a keystroke event to the active window (when I click on that key using a mouse).
My problem:
When I click on the key image, say G, I get the active window and send the key to it, but the active window (after the click event) is my programs window (it was activated because of the click on the letter G), so how can I get the previous active window or prevent my window from ever being activated???
Please its urgent,
Thank you!!!
And ever has it been that love knows not its own depth until the hour of separation

To answer the last question first, you can't, not without a lot of kludging. As for how to get the previous active window, what happens if there is a popup that the user must respond to, before clicking on the keyboard? This is non-deterministic, and it seems to me that a better way would be to invoke the on-screen keyboard (dialog, exe, whatever) with the HWND of the window that wants the key presses. If a dialog, pass the HWND as a parameter. If an exe, pass the HWND as a string parameter on the command line. That way you will know for sure where to send the click events.
Best wishes,
Hans

This is managed code, we are on the C++ forum.

Your code needs to a convertor to convert of managed code to unmanaged code

Its simple if you know managed programming you can convert it

Change the Id of the button to something else than IDCANCEL. That will solve the part concerning the closing of the dialog.
Concerning stopping the thread, it depends of your code. Is the thread running an 'infinite loop' ? (something like while(true) ). If yes, then you can check for a boolean and set this boolean to false when you press the button.

Hi,
Keep two buttons. One OK and another Cancel on the dialog. Keep a member variable in the dialog class of type CWinThread* say m_pThread. Now
create the thread in the OnOK() event handler as
m_pThread=AfxBeginThread(ThFunc,0,0); where ThFunc is the function pointer to your thread controlling function and the next argument is the argument passed to your function which I have passed 0 here. This function should be of type UINT YourThreadFunc(LPVOID pParam).
To stop execution of the thread write in the OnCancel() event handler
m_pThread->SuspendThread();
Hope this will help you.

If you can come up with some good advice and a real solution to the actual problem then put it there.

My advice was valuable: pointing out unsafe solutions is a valid point to make.

Look dude, I just pointed out that your solution was bad. This took me 5 seconds and one line of text. I post heaps of messages on this forum and make an effort to be helpful – when time permits. Now I’m sorry if you’ve been offended but nevertheless my post has merit and is informative. Perhaps not as immediately useful as a full solution: but knowing what not to do should not be underrated. Perhaps it’s taught you something for example.
