What part of what control are you interested in? Some controls have text, some do not. Some have borders, some do not. For starters, there's GetBkColor().

I wanted to get Color of a Dialog and set it a toolbar. I am able to get the color of dialog. How can I get color of other controls. Is there some generic way where I can get background color of control. What if the color is gradient. and wat about if it has bitmap as its background.
One other thing, How can then I set a background color of a toolbar, to be more specific. I have achieved to change bg color of static label but I am, not able to do it with toolbar. Any help ?
Regards,

Without a specific example, I can't say for sure.

This almost sounds like "skinning." Since that technology is all about painting the various parts of a window, I'd suggest a thorough reading of it.

Friends,
I usually develop 'ActiveX controls' using "MFC ActiveX Wizard". In the past, i simply develop ActiveX control and distribute it along with the client side application.
This time i am in different situation. As usual, i developed a control and distribute it with my client application. But now i've enhanced the same control. I've added some new interfaces and not touched the previous interfaces. I came to know from somewhere that there is a method of proper versioning of ActiveX controls and COM components. And i am required to 'increase' the version of my activeX control before distributing it.
Can anyone tell me how to control the version of those 'ActiveX controls' which evolve with the passage of time. Also tell me the method to do so in MFC ActiveX controls.

The problem i am facing is use of File stream.
My req is to share same open file with filebuff and fsrteam object
Please find the code snippet below
Compiler is not recognizing .fd()
Error is in this line int fdesc = v_AppFile.fd();
filebuf v_AppFile;
v_Fb = v_AppFile.open (strFileToOpen, 0);
int fdesc = v_AppFile.fd();

You can use MoveWindow[^] any time after the base class' OnInitDialog has been called.

There's also SetWindowPos().

Dear Friends,
This question is related to MS-Word automation. I want to find some statistics related to the opened word document. I've already found two statistics like count of total words and count of total characters using various word-automation interfaces.
I found some statistics indirectly, for example i wanted to calculate total number of characters in Bold in my document. There is no such support directly provided in MS-Word and automation functions. However i used "Find Dialog Box" and WildCharacters property to get the total count of these characters.
So far so good. Now i want to find some other statistics but i am struggling to find out and i require your help. I want to find the total number of:
--Bullets in my document
--Fonts used in my document
--Font sizes used in my document
Can anyone tell me that how can i computee these values via directly using Word or by automation.

Hi!
I have written a small system-wide hook dll in vc++ 6, I would like to generate from the Ctrl key an ALT key.
HOW can I from a wm_keydown message a WM_SYSKEYDOWN message generate?
Because the alt key is a special key..
if the ctrl was pressed down -> in the spy the wm_syskeydown msg. to be seen,
if ctrl is repeated ->wm_syskeydown,
if ctrl is released -> wm_syskeyup to be seen
AND the Ctrl+A to became an Alt+A event.
Thanks in advance!!

I would think you'd need to monitor ports 25 (SMTP), 110 (POP3), 80 (HTTP), and 21 (FTP). These are default values for a particular service, however. I know there is a way to find out which port is associated with a particular service but the name escapes me.

this does nothing?
where am I going wrong
the handle is not NULL but nothing happens

Your main thread exits as soon as it has created the second thread, so probably it destroys the second thread.
|
|
|
|
|
The main thread ends too soon. Try:
if (hThread==NULL)
MessageBox(0,"a","a",MB_OK);
else
MessageBox(0,"b","a",MB_OK);

As mentioned, the main is exiting before the thread can even execute. To wait for the thread to terminate, you can do a WaitForSingleObject(hThread, INFINITE);. This will wait for the thread handle to become "invalid," which occurs when the thread terminates. At that point, you should also do a CloseHandle(hThread); before exiting.

Here's what I'd usually do:
struct threadPkg {<br />
HANDLE hStartup, hStopNow, hShutdown;<br />
};<br />
<br />
UINT ThreadFunc (LPVOID lpParam) {<br />
threadPkg * pkg = (threadPkg *) lpParam;<br />
::SetEvent(pkg->hStartup);<br />
<br />
while (true) {<br />
switch (::WaitForSingleObject(pkg->hStopNow, 10)) {<br />
case WAIT_OBJECT_0: {<br />
::SetEvent(pkg->hShutdown);<br />
AfxEndThread(0, true);<br />
return 0;<br />
} break;<br />
case WAIT_TIMEOUT: {<br />
} break;<br />
}<br />
}<br />
}<br />
<br />
bool StartThread (threadPkg * pkg) {<br />
CWinThread * thread = AfxBeginThread(ThreadFunc, pkg, THREAD_PRIORITY_IDLE, 0, 0, NULL);<br />
<br />
switch (::WaitForSingleObject(pkg->hStartup, INFINITE)) {<br />
case WAIT_OBJECT_0: { return true; } break;<br />
case WAIT_TIMEOUT: {
return false;
} break;<br />
}<br />
}<br />
<br />
void StopThread (threadPkg * pkg) {<br />
::SetEvent(pkg->hStopNow);<br />
switch (::WaitForSingleEvent(pkg->hShutdown, INFINITE)) {<br />
case WAIT_OBJECT_0: break;<br />
}<br />
}<br />
<br />
void main () {<br />
threadPkg * pkg = new threadPkg;<br />
pkg->hStartup = ::CreateEvent(NULL, true, false, "startup sequence, thread->main");<br />
pkg->hStopNow = ::CreateEvent(NULL, true, false, "signal to stop now, main->thread");<br />
pkg->hShutdown = ::CreateEvent(NULL, true, false, "thread has shut down, thread->main");<br />
<br />
if (StartThread(pkg)) {<br />
StopThread(pkg);<br />
} else {<br />
MessageBox(NULL, "Error: The worker thread was not started.", "Critical Error", MB_OK);<br />
}<br />
}
What that will do is begin a handshaking process when you start up the thread. This function creates 3 events and do what the text description says. It creates the thread, then waits for the thread to tell it that it has started and is on it's feet. You can do what you want and the thread will continue working, occaisionally asking if it's been told to quit. When you are ready to stop the thread, the function is called and it sends the hStopNow singal, the thread catches it, quits nicely and simultaneously signals back it's received and has shutdown. This is the basic organization of my threads I use all the time. Of course, what happens in main depends on what you want, you can put the start and end thread functions however you need them.
Note: I just wrote that off the cuff, I haven't tested that exact code but it looks correct in it's entirety.
Good Luck
