My best guess is a "how to lock" a screen. You can draw a big form, maximized, borderless, on top of all the rest.

Can anyone point out the differences between Visual C++ 7.0 (.Net) and Visual C++ 6.0?
Thanks

For strict C++/MFC code, the compiler is a lot more compliant and strict; I believe there are minor changes to MFC and ATL to merge some classes ( I think the CString is one of them ).

Here are several Tutorials to DirectShow, also for Capturing. Perhaps you also want to have a look at the DirectShow Docs coming with your DXSDK.

pDoc2->get_all(&ppCollection);
Assert(ppCollection);
ppCollection->get_length(&Count);
for (long i=0;i<count;i++)
{
=""
="" _variant_t="" index="" ;
="" try
="" ppcollection-="">item(index,index,&ppvdispOption);
}
catch (...)
{
tagstr.Format("%d",i);
AfxMessageBox(tagstr);
return FALSE;
}
if(!ppvdispOption)
continue;
ppvdispOption->QueryInterface(IID_IHTMLElement,(void **) &pElement);
ppvdispOption->Release();

Hi,
I downloaded a sample mfc project that builds and runs fine. But when I add any ActiveX control on one of the forms, it fails to start. What could be the problem?

Could it be that the ActiveX control has not been registered? You can confirm this by ensuring that the dialog has the DS_NOFAILCREATE style.

Hi all.
I have a dialog, that is a plugin for another application.
The problem is that my dialog works nice when i launch it from the other application, except TASB navigation and shortcuts.
When i test the dialog from Layout->Test, the TAB navigation works nice, but when i try to use tab navigation from my dialog launched from the host application i am not able to navigate with the TAB key.
In addition accelerators keys don't work with my dialog.
Any clues, maybe i have to explicitely get the TAB control? how can i do this?
Thanks

Could it be that the other application is trapping (e.g., not processing) the tab key such that your dialog does not see it?

A tabbed dialog box (i.e., property sheet) has nothing to do with using the tab key to navigate controls on a dialog.

This is a sign that the other application is not calling IsDialogMessage, to give your dialog a chance to process 'dialog messages' like accelerators and tab keys between controls. Perhaps because it does not know that a dialog is up on the screen?
If the other application has a custom message loop, check it to make sure it at least does TranslateMessage() and DispatchMessage, but the handling you are missing is definitely performed by the IsDialogMessage call.

if you are coding in C++, the try / catch statement is the right one (as refered by the MSDN[^])

while(1)
{
try
{
// this->recvSock();
bytesRecv = recv( m_socket, recvbuf, 5, 0 );
AfxMessageBox(recvbuf);
m_TEXT.AddString(recvbuf);
}
catch(CException* e)
{
// AfxMessageBox("Error");
// e->ReportError();
break;
}
}
//the above is given inside a worker thread.. simple one  . works fine as the long as the client is alive.. goes mad when its closed.. loves client too much ??
Thanks

I'm not too sure about exceptions when it comes to winsock stuff, but try adding a check for bytesRecv == 0, and if so break:
if ((bytesRecv = recv(m_socket, recvbuf, 5, 0)) == 0)<br />
break;<br />
else<br />
....
If the other end of the link disconnects cleanly then recv should return 0 (zero bytes received). You would then, in the server, go back to a listen state waiting for a new connection. The reason you're printing out the last thing the server recieved over-and-over is because, as there's nothing to recv the buffer doesn't get overwritten.
Of course, this is all assuming you're using a connection oriented socket (TCP).
In theory the exception should pick up on the dropped connection, but as I say, I've not used exceptions with winsock comms.
Hope that's:
a) correct
b) helpful
