Try (36883.0 / 49024.0) * 24.0.
The compiler thinks you're declaring integers, because you aren't including the decimal point.
As mentioned above, integer division of your values results in zero.

How can I read/write registry entries in an mfc dll?
e.g. can I use the CWinApp interface ?
Thanks.

The same way you would in an EXE...with the registry API.

Thanks..
Okay, so I guess I cannot do it the MFC way ?
i.e.
CWinApp* pApp = AfxGetApp();
CString key = "Preferences";
CString f = pApp->GetProfileString(key,....
int l = pApp->GetProfileInt(key, ....
....
?????

Sure, you can use the CWinApp() methods, but they are slightly less flexible that the API itself. It really just depends on exactly what you are wanting storing and where.

Ok...so now my questions boils down to:
How do I get a CWinApp interface within a dll ?
in my experience AfxGetApp returns null in dll's...
Thanks again.

There are several decent registry classes here on CodeProject.
Why not choose one and use it?
Ignore the CWinApp stuff

Unless your DLL already uses MFC, you can't.

Right-clicking a button is not very intuitive. What exactly is it that you are trying to do?

i need to popup window dialog (something like menu popup),
the dialog/menu will popup on right click button.
|
|
|
|
|
Create a new class and inheriate the CButton class...
class CMyButton : public CButton
{
. . .
}
Then capture on the WM_RBUTTONDOWN message. Using the wizard for VC6.0 and the properties for VS2003.
In there do what you need to do.
Hope this helps.

No you have to make you own class derived from CButton!

 Don't you think MS already make you life easy by providing Inheritance to there proprietary classes

I need to read a data file using C++, it's a data file that contains a row of column headers before the actual data. I need C++ to remove the header and re-print just the data into a new data file. Any suggestions?

Are you using MFC? If so, then the following snippet should (it's untested) work for you:
CStdioFile in(<code>""</code>, CFile::modeRead), out(<code>""</code>, CFile::modeWrite | CFile::modeCreate);
CString strLine;
in.ReadString(strLine);
while (in.ReadString(strLine))
out.WriteString(strLine);
in.Close();
out.Close();
CFile::Remove(in.GetFilePath());
CFile::Rename(in.GetFilePath(), out.GetFilePath());A slightly harder-to-read, but more efficient, approach would look like:
CFile in(<code>""</code>, CFile::modeRead), out(<code>""</code>, CFile::modeWrite | CFile::modeCreate);
char c;
LPSTR pBuffer;
DWORD dwLength = in.GetLength();
do
{
in.Read(&c, 1);
dwLength--;
} while (c != 0x0a);
pBuffer = new char[dwLength];
in.Read(pBuffer, dwLength);
out.Write(pBuffer, dwLength);
delete [] pBuffer;
