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.

i'm using winsock.h for a simple c/s program.. in that, when i close the client.. the server is getting into a loop.. which keeps on prints the value previously received from the client...
how to handle the exception? i used try{ } catcb{} but i'm not sure it's in its correct form!.. plz help
Thanks,

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

Which is very bad programming practice. <slaps wrist>

instead of 0 if we check for -1 its working fine... i can trap it.. 
thanks,

Like I said, I've not used exceptions with winsock, so I'm not sure what it would catch. The recv will return 0 for a cleanly-disconnected socket, and -1 for some other error. I would have thought that the exception would catch the -1 case, leaving you to handle just the clean closure of the client.
But hey, if it works, it works

its Correct and its Helpful so thanx,thanx,thanx,thanx,thanx,thanx,

yes it will loop indefinately even if the client gets disconnected as catch() is not executed after the client is disconnected(ie.,bytesRecv =0).put the try catch on return value from recv.

?? return value can trow an Exception? r u sure? i'll try that too

tssss,
try / catch statement is used ONLY to catch thrown exceptions.
if no exception is thrown, you will never enter the bloc.
if you want to perform certain action depending a function result, just test it the simple way.

no. but the function which is call and suspected to return a value can not execute well to its end and throw an exception before the return instruction.

in java we have a particular Exception thrown when it finds the client is disconnected..just like
try
{
}
catch(UnknownHostExeption e)// not sure some other exception here
{
}
do we have something like that in C++ (winsock)..?
Thnx

I just download a server and client source code. But I do not know how to build it as my project. Can somebody give some guide.....I really a fool of computer programming...

Hi,
For compiling, you need a compiler. A compiler is free when you buy an IDE 
You can buy one here at codeproject with some discount, or download the free trial of Visual Studio 2005 beta.
Then open the project file and press the Build button. If you don't even know how to build, maybe it's an idea to ask the developers of the application to build it for you?

The source code that I downloaded are all in .cpp and .h and I don't know how to test it. I mean when I open the Visual C++ software and open the source code and click on the Rebuild button, it will prompt me to build a default workspaces. So,I click OK and it will compile. But I don't know how to link all the source code together so that I can compile and execute, and come out a DOS which is the final result of the source code. Hope that you understand what I was asking. I really don't know how to express my question.
I just want to use all the source code to become my project source code. The source code that I downloaded have two folder, one is client and another is server.
