Search for information on Windows Sockets. You should be able to find examples.

With sockets, on the server side try:

listen(socket, MAX_CONNECTIONS), after the call to bind().

Set MAX_CONNECTIONS with a define statement to some large value. I hope this helps you out.

(79) : error C2059: syntax error : ')'

I must be missing something somewhere, but it isn't obvious to me with such an ambiguous error msg...
I've tried every connutation of line 79 "(WindowOne ->Create(NULL,NULL,WS_CHILD,);", but none seem to help, unless I actually comment it out.
Is there another section of code where I should go to make edit corrections?
I've tried deleting the offending line and recompiling before retyping it back in to no avail.
Any help/advice is greatly appreciated! Smile | :)

The offending code...........

void CSplashScreen::OnGo()
{
// TODO: Add your control notification handler code here
CWnd *WindowOne = new CWnd;
WindowOne ->Create(NULL,NULL,WS_CHILD,);//line 79
WindowOne ->ShowWindow(SW_SHOW);

}

Try this

CWnd* pWnd = new CStatic;
pWnd->CreateEx
(WS_EX_CLIENTEDGE, // Make a client edge label.
_T("STATIC"),
"Dialog",
WS_CHILD |WS_TABSTOP | WS_VISIBLE |WS_CAPTION,
5, 5, 300, 300,
m_hWnd,
(HMENU)1234);

Thanks very much! This works, and I'm sure I will be ale to put it to good use. A question regarding the use of CStatic...
I want to be able to access the window produced as if it were a List box. The item choosen from this list box will be applied to a second window which will bring up the properties of the item chosen from the first window.
Can I do this with the CStatic window just created?

Thanks in advance,
Thomas

i think u r missing a few parameters, just try this one;

void CSplashScreen::OnGo()
{
// TODO: Add your control notification handler code here
Rect rect(100,100,200,200);
CWnd *WindowOne = new CWnd;
WindowOne ->Create(NULL,"Window One",WS_CHILD,rect,NULL,NULL,NULL);//line 79
WindowOne ->ShowWindow(SW_SHOW);
}

You missed out the rectangle, and other few parameters, just try this one out.

Cheers

Sorry i missed a thing, it is;

CRect instead of only Rect in the declaration, now ur code should look like this;

void CSplashScreen::OnGo()
{
// TODO: Add your control notification handler code here
CRect rect(100,100,200,200);
CWnd *WindowOne = new CWnd;
WindowOne ->Create(NULL,"Window One",WS_CHILD,rect,NULL,NULL,NULL);
WindowOne ->ShowWindow(SW_SHOW);
}

Hope this helps,

Cheers

There's a comma between "WS_CHILD" and the right paren.

MFC CString::Delete() don't work properly

toxcct24-Mar-05 6:16

the MSDN tells us :
int CString::Delete( int nIndex, int nCount = 1 )
throw (CMemoryException );
...
Remarks
If nCount is longer than the string, the remainder of the string will be removed.

i thought the following line of code would work :

m_strDateDay.Delete(2, INT_MAX);

but i'm afraid, it doesn't !!!
instead of this, it gives me an "Unhandled Exception in Prog.exe".
when i debug, i see that memcpy() is making the error within CString::Delete().

What does m_strDateDay.Delete(2, INT_MAX - 1) yield?

If that does not work, how about:

m_strDateDay = m_strDateDay.Left(2);

actually, i've already tried with INT_MAX - 1, and also with m_strDateDay.GetLength() (which i was certain at the moment that it was no longer than 5 chars).

i currently use CString.Left(), but i wanted to know if anybody had already encountered that problem, or could find a reason to that behavior...

So these two statements do not work for you:

m_strDateDay = "12345";
m_strDateDay.Delete(2, INT_MAX - 1);
m_strDateDay.Delete(2, m_strDateDay.GetLength());

Is that correct?

It's a bug. It has nothing to do with INT_MAX.
Actually, the exception is thrown if nCount is greater than the (number of remaining characters after nIndex) + 2.

Handle NM_CUSTOMDRAW in the tree control's parent window, and in the item-prepaint stage, set the text color to the gray you want.

Convert To Binary

Static(x)24-Mar-05 4:38

Static(x)

24-Mar-05 4:38

I have written class inherited from CString for doing arithmetic operations with huge numbers,but it takes too long to convert a decimal number to binary using standard algorithm(dividing on 2,...).
situation is like this:
i want to convert (for example)
CString g = "134.......45645675"; to Binary
//CString binary;
//binary=SOMEFUNCTION(g); binary = "10000100...10011"
can you give me any link where i can find information about converting from decimal to binary using shift left and shift right operaations,or give me any tipps,i think using these operations will make conversion faster.

Thanks in advance

I found this in my toolbox. It's old so adjust as necessary:

void DWORD_To_BinaryString( DWORD value,char string[] )
{    
    for (int bit = 0; bit < 32; bit++) 
    {        
        DWORD mask = 0x80000000 >> bit;        
         
        if ((value & mask) == mask) 
            string[bit] = '1';        
        else                        
            string[bit] = '0';    
    }    
    
    string[32] = '\0';
}
