I suppose something gets wrong into the dll... if you have the code of the dll, a clumsy solution would be to integrate the function into your main code, and watch the effect. Or make a separate program where you pass the same parameters as in your program (I still believe in the "Same cause, same effects" Smile | :)

)

I think however there should be a better way to do it ...

Load the DLL and the exe project into the same workspace. Make the DLL the active project, set your breapoints etc. When you run in debug (F5) point to your exe program as the one to run and go from there.

what i do is:
open that file of dll into exe in which u wish to go while debuging
u can do it like this
goto file menu option & select open(not open workspace)
then select the file of dll & say ok
if u set break points in that file & then debug the exe the control will go to ur dll file
u can open more then one dll file in exe & also navigate through them using window menu option

Catch WM_MOVING !!!!!

Hi,

I tried to catch a WM_MOVING message in a DialogBar subclass to make it snap to the borders of the mainframe client area when it is floating.

It doesn't work.

Apparently there is another parentwindow (my guess a MiniFrameWnd) built around it when it gets to be floating.

How can I catch or delegate this message in/to my DialogBar ?

Thx

It is possible you will need to use a custom CDockBar class to accomplish what you are trying to do.

That´s exactly what it is supposed to do, so do not worry Big Grin | :-D

I'd suggest :

m_MyCombo.AddString("hello spotty");
m_MyCombo.SelectString(0,"hello spotty");

Hope this helps...

CAsyncSocket reuse

I have Close()'d my CAsyncSocket, but wish to use the same object to restart communications with another socket. How do I go about opening it again? It returs an error, "Descriptor is a file, not a socket."

Thanks.

Hm, my socket objects are dynamic so I just create a new one on request.
If you want to reuse, how abour Close() and then Create()? Didn't try it, but a quick look into Sockcore.cpp shows no problem.

stupid me. of course I also reuse some objects:

m_ClientSocket.Close();	//create new socket (close any pending old socket before)
if(!m_ClientSocket.Create()) {
    m_ClientSocket.Output("** Unable to connect (network error)");
    return;
} //now connect!
m_ClientSocket.Connect(szAddress, nPort);

The best way is to get a new object via new.
Everything else makes your application crashing after some time.
i've tried many solutions but that one is the best, but you have to care about deleting at the right time.

Could you explain this problem a little more detailed? I use dynamic and static socket objects, my app runs stable... well, I think it does. Smile | :)

I dont know but the only thing I see at the bottom of IE is a standard statusbar. (IE 5.5 so maybe there is another bar in newer versions)

But the top Bar is a CReBar in case you're wondering.

Hi i've just started learning c++ with visual c++.net standard, after programming in java for about 3 years.

Im trying to build a simple QT example, copyed and pasted from there site. but im getting heaps of errors from qstring, qapplication,...
I have set the project director setting with the qt/lib, /include, /bin directorys.

This has to be a simple problem.
Any advice?
thanks.

This is the most simple example i wanted to start off with.
I created a new win32 project, the other project files are blank ( resources.h ,QT2.h )
Is it the way im creating the project?
The QT .lib,.h file paths are added to the project settings.
Is there a particular order they should be in?
Thanks for any help!

// QT2.cpp

#include "stdafx.h"
#include "QT2.h"

#include <qapplication.h>
#include <qpushbutton.h>

int main( int argc, char **argv )
{
QApplication a( argc, argv );

QPushButton hello( "Hello world!", 0 );
hello.resize( 100, 30 );

a.setMainWidget( &hello );
hello.show();
return a.exec();
