Friends,
I was playing with "Windows Media Player", suddenly an error occured in the application. A dialog box popped up on which the name of "cpp" was written and also the line number in "cpp" file also written where the error occured.
I also want to add such feature in my release builds. How can i do so ?

Use __FILE__ and __LINE__ constants to do it.
like this:
char lpBuffer[240];
sprintf(lpBuffer,"File: %s\n Line:%d",__FILE__,__LINE__);
MessageBox(NULL,lpBuffer,"Message",MB_OK);

I've subclassed CButton to draw the text with different fonts and font sizes. The problem is that when the focus rectangle is draw on radio buttons and check boxes it's size is relative to the default font.
Is there anyway to change the size of the focus rect or to draw it myself?
Thank you

You can draw a focus rectangle using DrawFocusRect() (or CDC::DrawFocusRect() if you're using MFC). You'll have to calculate the size of the rectangle yourself.

I know that! The problem is that when the control has focus there will be two rects. I was looking for a way to tell windows the size of the rect, or to disable windows to draw it so that I could draw it myself.

Good 
Unfortunately, you can't tell Windows the size of the focus rect.
The only way to prevent Windows from drawing the focus rect is to completely handle WM_PAINT without relying on the default at all. The best way would be to make an owner-draw control - then you wouldn't have to worry about subclassing it - MFC would do the hard work for you. You'd have to do all the painting yourself, but DrawFrameControl() could take some of the hard work out of it  .
Hope this helps

I'm handling WM_PAINT. But windows still draws de focus rect.

Try handling the WM_SETFOCUS/WM_KILLFOCUS messages and draw/erase the focus rect yourself (don't call the base).

I'd recommend creating an owner-draw control. Windows won't draw anything for an owner-draw control, and delegate everything to your control.

try taking a look at the classes present here in CP, my favourite is the one from Davide Calabro CButtonST, it has a lot of properties and it's great to learn how to manage things like what you want to do...
hope this helps...

Dear all,
This may seem like a strange question but I am working with some old 16 bit windows applications build with Visual Studie 1.52.
I was wondering if there are any way to force this application to have more process time from the OS?
Best regards

Windows 3.x uses cooperative multitasking, not preemptive multitasking like Win95 and later. If you just hog the processor, you cut out other processes.
From memory (admittedly, my Windows 3.x memory is a little bit rusty ), Windows only switches between processes when a process calls the Yield() or GetMessage() functions. If you call them less often, then you get more processor time, at the expense of other processes.

The 16-bit app runs in a 32-bit VDM process, so you can do the following:
Right click the app's pif and set the Idle sensitivity to low.
-or-
Boost the priority of the VDM process.

I necessary to do window, which there was inactive and always inhere over all windows (even over DirectX)
|
|
|
|

SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE|SWP_NOSIZE);

I necessary that window there was over DirectX, for instance over game and in game possible there was orderly play.

Yes. Look at the AlphaBlend() function.

... the middle button of my mouse in a dialog MFC app ? Is there any message associated to it (like WM_LBUTTONDOWN f.i.) ?

Hi:
Ok guys let me narrate the prob:
i've installed a windows hook monitoring some system events ,infact i am capturing the keb-keys,arrival of each message is followed by some writing of values in a text file .the writing of this key event was done in the
KeyboardProc()
present in the dll,but this did'nt work well because obviously i had to call the next hook in the chain as soon as possible but i was doing some file processing...
the result of this was that when i typed the keyboard-keys quickly ,i found that the file has not recorded the exact sequence of the keys, rather some keys were swaped ...for example
when i typed
"my name is ahmed"
i received something like this in the file
"my anme si ......"
this behavior is seen when i type quickly
i tried an alternative using Critical section in key keboardproc but this could not work also ,perhaps we can't block the system who calls the KeyboardProc().....
/************************************************/
ok guys i've changed my approach now but still some problems are there as explained below
now i am simply Posting the character(key) received in the keyboardproc() to a thread in a seperate process and calling the next hook imidiately as shown below
... KeboardProc(.........)
{
..............................................
/*hThread is the handle of the window associated with a thread in a seperate process*/
//imediately return after posting unlike SendMessage()
PostMessage(hThread,...,...,..);
return CallNextHook(..);
}
/***********************************************/
Message loop in the thread that is receiving messages from hook
while( GetMessage( &msg, NULL, 0, 0 ))
{
1: TranslateMessage(&msg);
2: AfxMessageBox(" key notification ");
//DispatchMessage(&msg);
}
My target is that the next key in the message que is not extracted from the que untill the previous has been processed..
Problem:
the problem here is that when i press a key i get an AfxMessageBox() as desired in the message loop , now when i press the second key without dismissing the "AfxMessageBox" that was showed for the first key,a new "AfxMessageBox" box appears and this keeps happening as long as i keep pressing keys so message window keep on increasing why is this happening.....?
Because the rule says if do not dimiss a messagebox the control should not go to the next statement.. so why the next message is processes while the previous message is still not completely processed
1: while( GetMessage( &msg, NULL, 0, 0 ))
{
2 TranslateMessage(&msg);
3 AfxMessageBox(" key notification ");
//DispatchMessage(&msg);
}
why the control goes to line 1 althogh the function on line 2 has not returned?..........................i dont want this to happen i used critical sections in the thread also but to no avail.........

Hi all,
I've got some files from our source control system, these are .c, .h, .Mak, and a MAKEFILE, and they compile to make a program.
My problem is I'd like to put them into a workspace and project, but am stuck on how to do this. Do I create the workspace then create a blank win32 console project, add the files in, and compile that way? I did this, but I get errors (I know the code works) concerning near and far keywords in the files, so I think I need to build according to the MAKEFILE but am unsure as to how to tell visual c++ to do this.
Any thoughts? I hope this is clear enough!
Obseve everything, remember more...
