I was trying to set an integer value returned by a function to one edit control. and I tried it in the following ways.

C++

CString str;
Int res = 2;
Str.Format("%d", res);
m_conrol.SetWeindowTextw(str);

or

C++

CString str;
Int res = 2;
Str.Format(_T("%d"), res);
m_conrol.SetWeindowTextw(str);

But I am getting an error like this

Quote:
.error C2664: 'CWnd::SetWindowTextW' : cannot convert parameter 1 from 'char [17]' to 'LPCTSTR

How can I correct this?
Anybody please help.

Can you try

LPCTSTR lpctSWT = str;
m_conrol.SetWindowTextW(lpctSWT);

and see if that works

Don't use SetWindowTextW, since the rest of your code is MBCS/Unicode switchable. Use the base SetWindowText (without the W) and let the compiler generate the correct version. So your code should be:

C++

CString str;
Int res = 2;
Str.Format(_T("%d"), res);
m_conrol.SetWindowText(str);

Note also the use of the _T() macro, you should use it for all string constants.
