Never mind - I see you're using an edit control. Did you enable its "multiline" property?

I'm not quite sure on how to do that.

Set the property in the resource editor.

If you're using MFC, there are quite a few CDC drawing functions you can use to do this. You can also use the Win32 analog functions that operate on a device context (i.e. an HDC).

I heard there are ways to do processing in memory using some dedicated API by Ms like VirtualAlloc(..) etc.
Anyone familiar with this and care to show some sample codes.
Just for learning.
Thanks

Does anyone know how to get the MAC address of the machine at the other end of a Windows Socket? i.e. Machine A listens to a Socket. Machine B connects. How can Machine A get the MAC address of Machine B? I see plenty of ways to get the local MAC, but none for the remote. Am I missing something obvious? Thanks!

I use ProfUIS library for that, the library is very good, easy to use. You can download free or trial versions of it: http://www.prof-uis.com/Overview.aspx

Needed to use straight CDC instead of CPaintDC or CClientDC.
I've found this code on msdn:
PAINTSTRUCT ps;<br />
CDC* pDC=NULL;<br />
pDC=BeginPaint(&ps);<br />
...<br />
EndPaint(&ps);
This results in a BIG memory leak. And I haven't got a clue.
Tried delete pDC; but that leads to a crash.

Try something like this:
CClient dcDisplay( this );
CDC dc;
dc.CreateCompatibleDC( &dcDisplay );
CBitmap bmBitmap;
bmBitmap.CreateBitmap( ... ); // How ever you want to do it
dc.SelectObject( &bmBitmap );
... GDI functions
<end of function, GDI gets released>

OOPs, never mind last...
Call EndPaint( &ps );
Don't delete the Pointer.

Sorry, but I found out that the leak wasn't caused by creating/destroying the DC.
It seems that the leak comes from dc.SelectObject(...). There's a thread about SelectObject() a bit higher.
I don't understand, cause it's standard code that you'll find anywhere on this site ...

I'm guessing that you did:
CPen pen( < Created stuff here > );
CPen* pOldPen = pDC->SelectObject( &pen );
< code stuff here >
pDC->SelectObject( pOldPen );
Something like that or:
pDC->SaveDC();
< Code Stuff here >
pDC->RestoreDC( -1 );

Could somebody explain the n in #pragma pack(push,n).
I understand the concept of packing data, that is "no" padding anyway around stored data, right?.But I'm having trouble with what this n is supposed to do the packing of the data.
I'm using .NET (C++).
Thanks.

n is the byte boundry. If you say #pragma pack(push,4) you have a 4 byte boundry.

For the most part, 'n' specifies the alignment. The easiest way to think of it is that if a structure element isn't a multiple of 'n' then pad bytes are added after the element to make it a multiple of 'n'.
Example:
4 byte packing (n=4)
char sz [3]; is a 3 byte element. To make the next variable in structure align properly, a single pad byte has to be added to the end.

I'm going to patent thought. I have yet to see any prior art.

"Unresolved external symbol"
It's in a dialog app that has some function declared in a C file and then prototyped in a header file. I include the header file in the file I call the function from and that is where I get the error.
I have tried a number of things but can't seem to get this to work.
Please help!
Thanks,
Jim

If the original header file was from the C Programming Language, then you need to add:
#ifdef __cplusplus
extern "C" {
#endif
... function defs...
#ifdef __cplusplus
}
#endif
