Hi
I have developed one Windows Service which runs after certain interval. It runs on Windows 2000 Professional OS.
Most of the code I have written in C++.
It's a multithreading application in which first when service starts it creates one thread called MasterThread. Then Master thread creates 100 ChildThreads.
First it creates all the 100 ChildThreads in to Suspended mode and when I need it I resume that thread.
The problem is like some time it creates only 20 Threads and it stucks execution over there. Some time it creates 80 threads or something like that and then it stucks. And some time it works fine creating 100 threads....
also sometime it gives error after running successfully for 2 to 3 hours. The error message Showing one dialog box like :
" Runtime Error!
Program : C:\Services|MyService.exe
R6025
-Pure virtual function call "
Does anybody know what these both problems are happening. Is there any limit on how many threads we can create on Windows 2000 and if we want to create more than that limit then what to do ?
Why it gets stuck after creating some number of threads...?
Pls help me...
Thankx in advance

Maybe there is a problem with the synchronisation between the threads. Make sure all variables shares between the threads are secured by mutexes, critical sections or other synchronisation mechanisms.
The error you described could be caused by a global class that is initialized by one thread, and accesses by another one at the same time. You have to be very careful with multithreading, it needs lots of planning that it really works without any problems.
Don't try it, just do it!

I've managed to host a web browser window in my program but am unable to work out how to handle events fired from the browser window. I know it has something to do with the DWebBrowser2 interface but how do you hook it up? The program is written in plain Win32 ie. not MFC, ATL etc.

I wanted to know whether , "kill" is a command provided by every windows OS , or what?
|
|

What kill command?? There is no kill command!
Don't try it, just do it!

No, it is not common to all. That would be one amazing utility since there are at least 54 different OSs[^]

Yes they are so many operating systems. But you can find the kill command in OS's like unix
-oam-
|
|
|
|

Of course, but re-read the original post again. It was whether KILL was supported on all OSs not whether it was supported on Unix.

Then we will be living in a new planet if it can be supported by all OSs.

In my MFC MDI application I'm trying to add some new entries to the "Help" menu.
I have an existing menu item with ID_HELP identifier, this works fine, and displays the correct message in the application status bar (as specified under ID_HELP in the String Table).
If I add a new menu item, say ID_HELP_NEW, and a new string in the String Table under ID_HELP_NEW - you'd expect that string to show in the status bar when you hover over the new menu item, yes?
However, regardless of my string table entry the application shows "Switch to the previous document window" in the status bar for all new entries on the help menu. Seems to be something automatic done by MFC. (I've deleted my "Window" menu, if that makes any difference).
Anyone have an inkling what isgoing on here?
Cheers,
Dan

Seems I was accidently reusing one of the default resource IDs, hence I was getting the wrong message. If I change my new resource ID to something lower, everything works fine!

i wish to use CFileDialog.DoModal() to save my file...
can anybody give me some guide on how to transfer my data in list box or list control to a txt file?

if you are a MFC user, the following should help :
CString str;
ofstream file("file.txt");
CListBox* pLB = GetDlgItem(IDC_LISTBOX);
int NbLines = pLB->GetCount();
for (int i = 0; i < NbLines; i++) {
pLB->GetLBText(i, str);
file << (LPCTSTR)str << '\n';
}

Here is the CFileDialog part only, the other part you asked was already answered....
static char BASED_CODE szFilter[] = _T("Text Files (*.txt)|*.txt||");
CFileDialog m_ldFile(FALSE,_T(".txt"),_T("file.txt"),OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, szFilter);
if (m_ldFile.DoModal() == IDOK)
{
CString strPath = m_ldFile.GetPathName();
}
