Looks like you're missing a #include.

Seems that would have resulted in:

error C2065: 'assert' : undeclared identifier

instead. With VS6, __MODULE__ is not even part of the assert() macro so I'm not sure what to even suggest.

Where did you get the __MODULE__ predefined macro from?

If you right click on "assert" and choose "Go to Declaration" then what file do you end up in?
It should be assert.h ( which you should be including with #include <assert.h> ).

In the RTL code with VS2003, it only uses these macros: __FILE__ and __LINE__

ya exactly,

assert(0);
and printf("\nHere %s %d \n",__FILE__,__LINE__); // for both statements I am getting the same error.

I included assert.h and tried but am unable to find the __MODULE__ predefined macro..

thanks in advance,

Ashok

Hmm I can't reproduce this at all. It works for me in console and GUI app builds no problems.

In Google search __MODULE__ shows up related to linux and python.
It's nowhere in the CRT or Platform SDK headers though.

C'tor of CString or assignement operator will take care of that.

e.g
CString csString(pCharArr);
or
Cstring csString = pCharArr;

I'll assume this is just bad English getting in the way of your actual intent. Otherwise, don't expect anyone to take you up on this. Creating an article is no small undertaking.

If you are simply wanting to know how to use such a control, have you Googled for:

CreateWindow("RICHEDIT_CLASS", ...);

Or at least looked here?

So why not just look at what MFC is doing? You'll notice a lot of EM_xxx messages are actually being sent.

should be reading. This is the core of Windows UI programming. You'll need to know it Smile | :)

You can use FormatMessage to see the description of the error, as in the following code excerpt (from MSDN)

LPVOID lpMsgBuf;
FormatMessage( 
    FORMAT_MESSAGE_ALLOCATE_BUFFER | 
    FORMAT_MESSAGE_FROM_SYSTEM | 
    FORMAT_MESSAGE_IGNORE_INSERTS,
    NULL,
    GetLastError(),
    MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
    (LPTSTR) &lpMsgBuf,
    0,
    NULL 
);
// Process any inserts in lpMsgBuf.
// ...
// Display the string.
MessageBox( NULL, (LPCTSTR)lpMsgBuf, "Error", MB_OK | MB_ICONINFORMATION );
// Free the buffer.
LocalFree( lpMsgBuf );

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

I am working on creating a drop down combo box if user clicks on a column in a list control. I have got one document in the link: http://www.codeproject.com/listctrl/CustomizedReportListCtrl.asp

But the problem is CBS_DROPDOWNLIST style has been used in that combo list. But I want to make that combo box editable. CBS_DROPDOWN is not working. Could anyone tell me how to do that?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
