Hi Guys I have wrote a VC++ program using MS_Visual Studio 2005 as single document interface and i difined a variable m_r1 as double,and i want to display the value of this varible on the screen so i wrote this code in the On_Draw function of the view class pDC->TextOutA(10,20,pDoc->m_r1,10); but when i compiled the program i get an error message error C2664:'BOOL CDC::TextOutA(int,int,LPCTSTR,int)':cannot convert parameter 3 from 'double' to 'LPCTSTR' pls how to overcome this problem and what can i do to display any type of variable on the screen "the only working one is of type CString"
