Capture the screen?

How could I divide the screen into 32 pieces after I capture the whole desktop in server application, and then send those data directly to client application, and at last scrabble them up to the whole image(Bitmap format) and show it on client? D'Oh! | :doh:

One day a pretty girl asked me:"Do u think you are handsome?" "I don't think so!".She gave a slap in my face:"Why lying?"...

I mean there is a server application, you can get the desktop(bitmap format) of it via client application, of course the bitmap data were sent by socket! My question is how could I send the bitmap to client? But do not send all bitmap data at one time, divide the bitmap into 8*4=32 pieces and then send them in order!

Variadic Macros

I want to use variadic macros in C using Visual C++ 6.0, as explained in MSDN[^]:

#define CHECK1(x, ...) if (!(x)) { printf(__VA_ARGS__); }

The compiler is giving me C2010 error Dead | X|

. Is it supported in Visual C++ 6.0? Unsure | :~

If yes, what should I do to compile this code?

If there is an alternate to variadic macros in C, it will be helpfull.

#define CHECK1(x, args) if (!(x)) { printf(args); }

BTW, i have a question. why do you want to do such a thing ? to print only in debug ?
if so, you could do a better design, like this :

#if defined(DEBUG) ||defined(_DEBUG)
    #define DBG_PRINT printf
#else
    #define int DBG_PRINT(const char*, ...) { return 0; }
#endif

this way, you can place some DBG_PRINT("whatever"); in you code ; it will be executed only in debug mode compilation.

#define CHECK1(x, args) if (!(x)) { printf(args); }

How do I pass multiple arguments, e.g. I want printf("%i %i", a, b); D'Oh! | :doh:

#if defined(DEBUG) ||defined(_DEBUG)
    #define DBG_PRINT printf
#else
    #define int DBG_PRINT(const char*, ...) { return 0; }
#endif

This does not compile under VC6:->

overide the WM_CTLCOLOR message. and write the following code there

HBRUSH CTestDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) <br />
{<br />
	HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
	<br />
	if(  nCtlColor == CTLCOLOR_DLG)<br />
	{<br />
        return (HBRUSH)::GetStockObject( BLACK_BRUSH );<br />
	} <br />
	<br />
	return hbr;<br />
}

{

if( nCtlColor == CTLCOLOR_DLG)
{
static CBrush MyBrush;
if( !MyBrush.m_hObject )
{
MyBrush.CreateSolidBrush( RGB(RGB(255,255,0)));
}
return MyBrush;
}
return hbr;
}

it better if u change MyBrush as member varaiable of that class

i am tryng to move a rectangle placed in CStatic object, the CStatic object is in a child window of the application.every time i move (on LButton Up)the rect it goes out of the CStatic object and goes to the corner of the client screen. I want it to remain within that CStatic object(rectangle)but it just flies out please help me. currently i m moving it with the help of SetWindowPos();
Should i get the coordinates of the CStatic object, then what??? Sigh | :sigh:

give the SWP_NOSIZE flag while caling SetWindowPos(..). The width and height will be maintained if u metion that one.
