I have SDI application in which there are two dialogs which are opened at run time.
One dialog is modeless and onclick of button on this modeless dialog One modal dialog is coming. Now based on selection of listbox on modal dialog I want to fillup
fields on modeless dialog.
For the same I require the object of class which is running in memory.
How to achieve it.

Not possible, since the modal dialog must be dismissed first before the modeless dialog can continue processing its messages.

This makes no sense. Please elaborate.

Actually I myself was able to do it

cnc was object of my modeless class.
what I done is I declared it in MainFrame.h
Then by (CMainFrame*)AfxGetMainWindow()->cnc I was able to get
object of modeless class in modal dialog. From cnc I was
able to access all fields on form and everything worked out well.

Modification -- yes modal dialog closes once I confirm selection,I didnot mentioned that
condition,and I think that is even possible for a separate thread.

oh man, that's too large topic to cover in a simple thread...

buy a book about MFC or Win32 and learn about it like this... but if you don't know C/C++ yet, i highly advise you to either learn those languages first, or move to a more easier one like C#

1) speak - correct - english
2) understand you books
3) try their examples/samples
4) ask specific questions

your issue(s) are too generals... no one can help.

explain what you already tried and where you're stuck, and then we'll see what we can do for you.

Doing it in .NET is not MFC, you should ask in the C++/CLI forum. But, if you're going to ask such broad questions, yes, buy a book.

If some other program launches my MFC application from command line, such as
test.exe /a /b
is there a way to return the Exit Code to the caller?

If the caller launches my MFC application with CreateProcess, then my MFC application should return the Exit Code with ExitProcess, right?

If the caller runs a batch (script) file to launch my application, how do I do to return the Exit Code?

Thanks!

~~using the %ERRORLEVEL% environment variable for instance ?!~~

my bad, i uinderstood "how do i get the return code ?".
anyway, have you tried something Maxwell ? i think it should work if you're just using the exitprocess, or the exit() function from the CRT, but all depends what you're doing in your application...

The customer said in the email that they have a master program to invoke my application, but they have not told me how they do to run my application yet.

So I was thinking, if they are running a DOS-box (command prompt) script batch file ... ? Confused | :confused:

C:\ test.exe /a /b
C:\ _ <--- Show nothing. :->

You can override ExitInstance method of your App class.
For instance, the following override make the application to return 5:

int CMyApp::ExitInstance() 
{
  CWinApp::ExitInstance();
  return 5;
}

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

You can use GetWindowLong() or GetWindowLongPtr() to get the window style after the window is created. And you can use SetWindowLong() or SetWindowLongPtr() to modify the style.

If you are creating the window with CreateWindow() or CreateWindowEx() then you can simply pass the styles combined with the bitwise | operator.
