DrawText doesn’t work like printf or something like that.
I advise you to look at the MSDN:
MSDN: DrawText
int DrawText(
_In_ HDC hDC,
_Inout_ LPCTSTR lpchText,
_In_ int nCount,
_Inout_ LPRECT lpRect,
_In_ UINT uFormat
);
You need to make a conversion to LPCTSTR, you can have a look into Google, if I find a link i will give it to you, but it make long time i haven’t do C++.
Edit:
I found :
int number = 1;
CString t;
t.Format(_T("Text: %d"), number);
and then DrawText(XXX, t, XXX, ...);
