maybe you sould take a look at WaitMessage(VOID);

I had a suspicion something like that was there but I just couldn't find it. Thanks. Now to try to figure out the menus.

Try replacing:
<br />
while( true )<br />
{<br />
if( PeekMessage(...) )<br />
with
<br />
while( GetMessage(...) )<br />
GetMessage stops the program for running while waiting for a message, while PeekMessage doesn't, and you have a loop running at full speed.

Good call, I was wary of the `while(true)' loop.
|

Shouldn't that message loop be:
while (GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(msg);
DispatchMessage(msg);
}

Yes, as long as this window message handling loop is not responsible for any dialog boxes.
Otherwise, and you need to know the dialog box's window handle:
while (GetMessage(&msg, NULL, 0, 0)){
if( !IsDialogMessage(hWndDialogBox, &msg) ){
TranslateMessage(&msg);
DispatchMessage (&msg);
}
}
You also might want to break if the message is WM_QUIT.
Now, the new and improved suggestions, from MSDN is:
BOOL bRet;
while( (bRet = GetMessage( &msg, NULL, 0, 0 )) != 0)
{
if (bRet == -1)
{
// handle the error and possibly exit
}
else
{
if( !IsDialogMessage(hWndDialogBox, &msg) ){
TranslateMessage(&msg);
DispatchMessage (&msg);
}
}
}

Hi all,
I was wondering if anyone could refer me to some c++ class that can be used to generate xml code from a dtd file. If not, then if someone knows of a class that can be used to validate a dtd file and/or tokenize it; not validate xml using dtd, but make sure that a dtd file is "valid".
Thanks in advance,

I'm not sure, but I'd lean towards the IXMLDOMDocument interface and its methods.

I looked into this class, but I am pretty sure it doesn't provide this functionality. I have not been able to find any class that will generate a basic valid xml document from a dtd file.

HI
I am getting error in executing a program ..It says that a dll file is not found.
How do I fix that?
Thanks

Supply the missing DLL, perhaps, or at least ensure that the DLL is located in one of the paths pointed to by the PATH environment variable. Without any more detailed information than what you've provided, I can't offer much more.

Thanks for reply
I don't understand how to ask...But let's see....
I don't know how to add that DLL file. I don't know why it is looking for that DLL file.
What do you mean when it says that
"Installing the file can fix the problem" ?
Thanks

Use Dependency Walker or Dumpbin to find out what DLLs are required by the application. Those DLLs, and possibly others, must exist on the target machine.

Isn't that self-explanatory? If the file existed and could be located by the OS, the problem would not exist.

I know that's self explanatory but I didn't know where from install the DLL file.

And you assumed someone here would, given that you did not provide the name of the application or the missing DLL?

The missing DLL is MSNHook.DLL
Tell me where to find this?

I believe, First you have to build the dll project come with you sample application.

I'm having trouble when I export an image as a bitmap on a 16-bit color system (seems to work well under 24 or 32 bit color). The strange thing is that when I bitblt the image to the screen, it looks right but when I save it to a file, the colors are completely off (I mean completely) though the image is not distorted in any other way. I'm pretty sure this has to do with my lack of understanding of bitmaps and 16 vs 32 bit color.
How is each pixel represented. I'm guessing it must be an index, not an actual color value since there are only 2 bytes available. Here's how I build the bitmap header structure:
<br />
BITMAP bm; <br />
bitmap->GetBitmap(&bm);<br />
bm.bmBits = new RGBQUAD[640*480];<br />
bitmap->GetBitmapBits (sizeof(RGBQUAD)*(640*480), bm.bmBits);<br />
<br />
BITMAPINFO BitInfo;<br />
ZeroMemory(&BitInfo, sizeof(BITMAPINFO));<br />
BitInfo.bmiHeader.biSize = sizeof(BITMAPINFOHEADER); <br />
BitInfo.bmiHeader.biBitCount = bm.bmBitsPixel;<br />
BitInfo.bmiHeader.biHeight = -bm.bmHeight;<br />
BitInfo.bmiHeader.biWidth = bm.bmWidth;<br />
BitInfo.bmiHeader.biPlanes = bm.bmPlanes;<br />
BitInfo.bmiHeader.biSizeImage = 0;<br />
BitInfo.bmiHeader.biCompression = BI_RGB;<br />
<br />
BITMAPFILEHEADER BmHdr; <br />
BmHdr.bfType = 0x4d42;
BmHdr.bfSize = (((3 * bm.bmWidth + 3) & ~3) * bm.bmHeight) + sizeof(BITMAPFILEHEADER) + sizeof(BITMAPINFOHEADER);<br />
<br />
BmHdr.bfReserved1 = BmHdr.bfReserved2 = 0;<br />
BmHdr.bfOffBits = (DWORD) sizeof(BITMAPFILEHEADER) + sizeof(BITMAPINFOHEADER); <br />
BitInfo.bmiHeader.biCompression = 0;<br />
Does anyone have any ideas?

how are you viewing the BMPs ?

I'm viewing the bitmaps via a photoshop and the built in preview app in WinXP.

the only thing that looks even a little off is the bmSize calculation, because that looks like it assumes 32 bit pixels. but that shouldn't affect the colors - most programs don't care about that value.
what does your BITMAPINFOHEADER struct look like after you've filled it in ?

Thanks again for all your help with this. Here's the bitmapinfoheader structure just before it's written along with everything else, to disk:
- BitInfo.bmiHeader {...}
biSize 40
biWidth 320
biHeight -260
biPlanes 1
biBitCount 16
biCompression 0
biSizeImage 0
biXPelsPerMeter 0
biYPelsPerMeter 0
biClrUsed 0
biClrImportant 0
