DDX_Time isn't part of the standard MFC DDX. It may be a custom type, have you included the correct header files. MSDN refers to DDX_Time as part of the possible User extensions but doesn't give a full implementation.

You can override the OnCreate member function, and create controls dynamically there. And handle the command BN_CLICKED of the Ok button and put there your own DDX ....etc. etc.
I think this seems complicated and useless. What do you want dynamic dialog box for? Could you not create the dialog box in resource editor and only make the specific controls visible/invisible at runtime?

Thanks for your reply,
But I have to create OCX of my Dialog so, I want to create DialogBOx without Resource. Any how I got answer and will post this artical on codeproject as soon as possible. But the real problem is even I am able to create DialogBox Dynamically. I am not able to attach the controls to it dynamically. Once I get this answer I will post it as soon as possible.

Web control in modeless dialog steals focus

Salvador Dali15-Dec-03 23:23

15-Dec-03 23:23

I have a web control inside a modeless dialog in view/doc application. The dialog is implemented as a child of the mainframe. The problem is, when something changes in the web control (navigate2() is called), the dialog steals the focus from the mainframe and view.

Is there any way to prevent this, or restore focus back to the previous window who had it?

Use the GetModuleFileName() API.

CString strDirectoryPath;
TCHAR zName[MAX_PATH];
TCHAR* zLast;

::GetModuleFileName(0,zName,sizeof(zName));
zLast=_tcsrchr( zName, (TCHAR)'\\');
if (zLast)
    *(zLast+1) = (TCHAR)'\0';

strDirectoryPath = zName;

///////////////////////////
ASSERT( !strDirectoryPath.IsEmpty() );
///////////////////////////

return strDirectoryPath;

Thanx i guess this piece of code is little better.

CString strAppPath;
::GetModuleFileName(NULL,strAppPath.GetBuffer(MAX_PATH),MAX_PATH);
strAppPath.ReleaseBuffer();
strAppPath = strAppPath.Left(strAppPath.ReverseFind('\\'));
AfxMessageBox(strAppPath);

you can also check the GetCurrentDirectory() in the Platform SDK out:

Current directory is not what i want, i wanted the location of the exe file.
suppose the exe file is in c:\windows
and if you execute the program from c:\temp then c:\temp is ur current directory and c:\windows is the source directory
