Thank you for your reply! I am quite a newbie taking on a project a bit over my head so here it goes:
I am adding the stdafx.h file in a .cpp file that samples the UAV state. I did not overwrite the stdafx.h in the Release folder (perhaps that's what I need to do?). The host program is a UAV simulator GUI program. The headers I'm trying to insert are for a vibrotactile vest. This will give pilots additional guidance cues.
Your DLL approach sounds like the way to go. Could you explain how you do this a little more? Thanks again.

Hello,
The sole purpose of the stdafx.h is to speed up compilation by precompiling the headers that you include. One simple solution might be to include the headers you need directly and do not use stdafx.h. See what that brings you.
I assume that you know what DLL's are. If you can redesign your applications, you can group the simulator API and compile that into a DLL. A search here on CP for DLL brings you, among others, the following articles:

Thank you again for your reply and the refs to DLLs. Sorry for my ignorance -I didn't really know what they were. After reading about them, I've come up with a plan:
1. The host program (executable) can export the UAV status to the DLL (cyclically)
2. The DLL is run with each call to it and can then control the tactile vest (as the execuatable sends the status)?
My assumption is that, in this situation, the DLL is like a separate execuatable but yet an included piece of code, in one (thus eliminating my library conflicts and other integration problems). Does this seem right? Thanks again.

Hello,
I don't know if it's wise to spawn threads in a DLL. (Are you doing this?). Your library conflics are resolved if you use the DLL approach.

Thanks for your reply. I guess it would be a DLL spawning a thread which would terminate with the signal sent to the tactile vest (although the vest requires the use of a killable timer as well). Are there some serious processing issues in this?

Hello,
I don't know if there are serious issues since I don't know the context. If you spawn the thread often and kill it often, you might have troubles since thread creation is an expensive operation.

Hi people,
I want to use the CTreePropSheet (by Sven Wiegand). I have a group of dialog boxes, say dialog 1, dialog 2, dialog 3. These dialogs have controls in them too, there are actions to be perfrmed based on events of those controls. Sven Wiegand has beautifully explained things out there. But I still dont understand how to do what I want. Can anyone please explain me how to do this (Step by step)? Your help is highly appreciated. Thanks a lot in advance for all of you PRO's. (Actually i've been doing a lot of C++ and not anything great in MFC, I am new)
Regards and thanks,
Rajesh R. Subramanian

I found out the answer myself.
After adding the required files to my project, I must make sure that my dialog boxes which has controls and which has to be added to the tree control should be derived from CPropetyPage instead of CDialog.. That's it.

I hope I am not asking too much.
Using an image list, I want to place some images into controls. I've got an image strip of 32x32 bitmaps - 5 of them. Upon loading these images and showing them, they are getting reduced to 8bit images. They are in my resources.
Why doesn't this work?
CBitmap ImageStrip;
ImageStrip.LoadBitmap( MAKEINTRESOURCE(IDB_DESKTOP2) );
HIMAGELIST hList = ImageList_Create( 32, 32, ILC_COLOR16, 5, 5 );
ImageList_Add( hList, (HBITMAP)ImageStrip.GetSafeHandle(), (HBITMAP)NULL );
CImageList ImageList;
ImageList.Attach( hList );
m_Grid.SetImageList( &ImageList );

or this....
CBitmap ImageStrip;
ImageStrip.LoadBitmap( MAKEINTRESOURCE(IDB_DESKTOP2) );
CImageList ImageList;
ImageList.Create( 32,32,ILC_COLOR16,5,5);
ImageList.Add(&ImageStrip,RGB(255,255,255) );
m_Grid.SetImageList( &ImageList );

Add ILC_COLORDDB to the flags, I see weird color problems sometimes when I don't use that flag.

Sorry, no. The last version that could was VC++ 1.52, available (but no longer supported) via a MSDN subscription.

I'm pretty sure I saw an intro to C++ book once that came with VC 1.5 on CD.

Pinky, are you pondering what I'm pondering?
I think so Brain, but if we shaved our heads, we'd look like weasels!

In this class:
http://www.codeproject.com/printing/printlib.asp
I can print text on top of a bitmap. Is there any way to
print text on top of other image formats, like a tiff or
jpeg? Or are the any other demo projects that involve
printing text on top of images?
Lets say I have a bitmap of a form that consists of black
and white text. Is there a way to determine what all of
the pixels of that bitmap are and store the pixels some-
where?
Please, any response any one can give me will be greatly
appreciated.
Sincerely,
Danielle Brina (an overworked graduate student)

Hello everyone!
OK, here's my code:
<br />
void ParseFile(CString);<br />
<br />
BxBeep * beeps;
<br />
int numOfBeeps;
It gives me:
BipFile.h(40): error C2059: syntax error : 'constant'
Why is that? Thanks! 
PS: This is inside a class declaration.

Is BxBeep defined?
Look at the previous line too. Often the actual error is in the line before the one flagged by the compiler.
