To display the series on the same line, simply construct the string and use TextOut() to display it, as in:

CString strNumbers;
for (int nNum=1; (nNum <= 50); nNum++) {
CString strNum;
strNum.Format ("%d ", nNum);
strNumbers += strNum;
}
VERIFY (pDC->TextOut (10, 10, strNumbers));

Hi Surivevoli, CString Str; int i=0; while(i<50) { Str.Format("%d",i); dc.SetBkMode(0); dc.TextOut(X,50,Str,Str.GetLength()); X+=20; i++; }

use wsprintf to add number in string and you can easily display that using the TextOut, but IMHO you should use CDC::ExtTextOut for same!

Thank you ! dc.SetBkMode(0)is uderstanded as dc.SetBkMode(TRANSPARENT)??? if before i draw a rectangle filled Red color {i use CBrush ...}, i try release that command{dc.SetBkMode} and use TextOut() to draw number text on the rectangle, but i see nothing changed if i want display formated "01","02","03",... Can you help me ? Lgx -- modified at 6:34 Saturday 8th April, 2006

what's difference between TextOut() and ExtTextOut() ??? why should you ExtTextOut()??

[Surivevoli]

i don't understand final code : VERIFY (pDC->TextOut (10, 10, strNumbers); what's it mean ? Lgx

Surivevoli, CString Str; int i=0; while(i<50) { Str.Format("0%d",i); dc.SetBkMode(0); dc.TextOut(X,50,Str,Str.GetLength()); X+=32; i++; } -- modified at 7:13 Saturday 8th April, 2006

VERIFY means to verify that your statement is properly fired or not.. try you local copy of msdn for these keywords

//Now test this code then again test without SetBkMode CPaintDC dc(this); CString Str; int i=0; dc.FillRect(CRect(0,50,800,80),&CBrush(RGB(120,120,200))); while(i<50) { Str.Format("''0%d''",i); dc.SetBkMode(0); dc.SetTextColor(RGB(255,255,255));//White dc.TextOut(X,55,Str,Str.GetLength()); X+=40; i++; }
