Hello,

I am having problems in justifying a text which is placed in a rectangle. I have placed the text inside the rectangle using DrawText() method, with DT_WORDBREAK flag so that the text can be clipped and can appear in multi lines. If i opt for this, the text is aligned Left or Right. Its not justified. Therez another method of SetTextJustification() which is used with TextOut and extTextOut(), if i use ExtTextOut (since i have to place the text in a rectangle) the text appears in a single line, without any clipping.......this remains a problem. can any 1 provide a solution which can place the text in the rectangle which is justified.

Thanx

Nadir

I think DrawText and Textout can't justify text.

You can use a RTFControl (Has to be Version 2.0 or higher)

* create an invisible RTF Control (be sure to use RTF2.0 or higher)
* Set Text with SetWindowText
* SelAll
* SetParaFormat with paraformat2.wAlignment to PFA_JUSTIFY
* set target device EM_SETTARGETDEVICE
* set wrapmode
* use EM_FORMATRANGE to draw content to a dc

have a lot of fun

yes you can !

Create one or more instances of CRichEditCtrl !
I would not use the standard create method of MFC because it uses RTF Version 1.0. It is important to create it without WS_VISIBLE Style

To create Version 2.0 or higher you have to use
LoadLibrary("riched20.dll")

see msdn LoadLibrary("riched20.dll")

1-To create CAsyncSocket varaibles in array and dynamically.
2-To create CAsyncSocket pointers in a threads.

But I don't know none of them.
Please Help me!

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.

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

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

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

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?
