You could probably, pretty easily see if the browser is running (using
something like FindWindow() which works, but is sometimes unreliable), but
it would be more difficult to keep track fo the content. Is there a
restriction on your help where it can't be run multiple times? I sometimes
like to open the same help to different pages.

I'm using the simple function below to run up my HTML help file but I
need a method to test if it already running.

Any ideas?

void CMainFrame::OnHelpChm()
{
CString strFileName;

CString strName;

char szBuffer[_MAX_PATH];

GetModuleFileName(AfxGetInstanceHandle(), szBuffer,
sizeof(szBuffer));

strFileName = szBuffer;

strName = strFileName.Left(strFileName.GetLength() - 10);

strFileName = strName + _T("easynn-plus.chm");

if(ShellExecute(NULL, "open", strFileName, NULL, NULL,
SW_SHOWNORMAL) <= (HINSTANCE)32)
{
AfxMessageBox(_T("No HTML Help application can be found."));
}
}
