I have written a code that has a window procedure for the main window. I trapped WM_CHAR message and wrote this code:
98 ......
99 case WM_CHAR:
100 MessageBox(hwnd, TEXT("KJHGKIF"), TEXT("KHTIUYT"), MB_OK);
101 return 0;
102 ......
(hwnd is a handle to the main window)
when run, I press a key and see a message box. at this time, window procedure is stopped at line 100. when I move messagebox, the client area of the main window is repainted. meaning that WM_PAINT is invoked. how can it possible? window procedure is running at two points?
|
|
|
|
|
Yes it is possible (and normal). messagebox has a dialog box loop ( something that reads message from the queue and dispatches them) which does not exit until you press one of the buttons. All modal dialog boxes have this. This allows other windows to be repainted when you move your dialog box (or to deal with timers or all sorts of events).
It looks like multi threading but it is not!
|
|
|
|
|
I guess the method is something like this: the function pushes all its data onto the stack, calls itself, after finish it pops the data back and continues its process. like the function for calculating n! (n! = n * (n - 1)!).
I guess messagebox sends a WM_PAINT message to its parent window using this method (and also when we call SendMessage function from the window procedure to send itself a message). is my guess true?

Absolutely true... it is absolutely like a recursive call

I have an MDI application created using VC++ 6.0. It has several dialog based executions. Now I want to seperate one such dialog based part and create a seperate new dialog based application.
Any suggestions, steps or points to be considered will be appreciated. Thank you in advance 
|
|
|
|
|
Use the wizard to create a new dialog-based application. Copy/paste your dialog resource(s) from the original application to the new app; note that it's sometimes easier doing this by editing the .RC file in the source editor rather than the resource editor. Copy/paste the dialog classes as well.
This assumes, of course, that the dialog functionality is self-contained, and doesn't rely on the rest of the application. If this assumption isn't valid, you are going to have more work ahead.

Please have a look at the below code patiently..
hi i've done the simple version of client server application.. i've handled the abrupt disconnection of client (not using Try/catch).. its fine.. but please tell me how to reconnect to the client which wants to connect again.. what i've done is
GetDataThread()
{
while(1)
{
if (client disconnects)
{
break;
}
}
RestartSock(); // comes here after "break"
}
RestartSock()
{
EndThread(GetDataThread); that Continuously looks for accepting data from client.
initSock(); ---->ok
bindSock(); ------>ok
listenSock();---->ok
acceptSock();----------->NOT OK ... the ctrl's not going abov this  .(see Acceptsock)
AfxMessageBox("Client Connected");
AfxBeginThread(GetDataThread,this);
}
void acceptSock()
{
SOCKET AcceptSocket;
while (1) //waits for client to connect
{
AcceptSocket = SOCKET_ERROR;
//NOT COMMING OUT OF The BELOW LOOP WHEN THE CLIENT CONNECTS THE SECOND TIME...
while ( AcceptSocket == SOCKET_ERROR ) ------->
{
AcceptSocket = accept( m_socket, NULL, NULL );
}
m_socket = AcceptSocket;
AfxMessageBox("Client Connected");
break;
}
}
for the first time everything is fine... but when the client tries to connect second time.. the client says that Its Connected but its not done.. the Server goes into the ACCEPT Loop.. please help me out...
Regards,
V

I have a function that will draw to an HDC, I need to create a bitmap from that, what would be the best method? Can I create a bitmap and get it's HDC or something like that?
Thanks!

Try to use
HBITMAP CreateCompatibleBitmap(HDC hdc, int nWidth, int nHeight);
OR
CDC* pDC = CDC::FromHandle(hDC);
CBitmap* bitmap = pDC->GetCurrentBitmap();

I want to execute an application in a computer different from the one where I've developed it. The computer doesn't have VC++ installed. After copying the folder, with the exe, the OCX (I've already registered it in the target computer) and a dll used, I execute the exe and I receive a windows error (the typical popup window prompting to report the error to Microsoft) pointing that the problem is in mfc42. I've replaced this dll with the newest one and the problem persists.
It has to be something related with the use of the OCX because a simple MFC app works perfectly...
Any idea about what's happening?
thanks in advance,
Marc Soleda.

No, I haven't created, it's MSChart component (MSCHRT20.ocx).
I've tried in debug mode and the crash is at winocc.cpp file, line 345 that is:
ASSERT(m_pCtrlSite != NULL); // not an OLE control (not yet, at least)
Do I have to do something else than "regsvr32 MSCHRT20.ocx" ???
Thanks,
Marc Soleda.

I've finally found that the crash is because I'm trying to modify some properties of the MSChart. The real problem is that the MSChart is not viewed in the computer without Visual Studio installed and then crashes when I modify properties because when I call the MSChart::Create method to create it dynamically at runtime it return FALSE but I can't find the reason.
So, what else do I need to do if I've registered it ("regsvr32 MSCHRT20.ocx") ??? 
Thanks,
Marc Soleda

have you registered the OCX on the target computer?
from cmd prompt type:
regsvr32 mschart.ocx
assuming that mschart.ocx is the filename

Yes, I did it and it's displayed in the problematic machine if I've added the component by dragging it to the dialog from components toolbox but if I create it dynamically (CMSChart::Create) it fails.

I know it has been a while since anyone has posted a comment here, but I just had to say something....
I have been working with MSChrt20.ocx for almost a year now and I have never been able to use CMSChart::Create. I think it has major problem that will not work at all.
I have noticed may problems with MSChrt20.ocx that I had to fix in my wrapper class. This is one that I have been unable to fix.
