Hi, Take a look at the following piece of code: int Length; TCHAR szBuffer[40]; // Warning point strcpy(szBuffer, TEXT("Line : %d X : %d Y : %d", i, x, y)); Length = wsprintf(szBuffer, TEXT("Line : %d, X : %d, Y : %d"),i, x, y); TextOut(hDc, x, y, szBuffer, Length); The code works fine but gives a WARNING Message as under: E:\My Documents\My Projects\Writing Text\Messages.cpp(101) : warning C4002: too many actual parameters for macro ''TEXT'' I am using Visual C++ 6. The program works fine, but warnings can create a lot of trouble in some cases. There is something to do with TEXT. Even if I initialize szBuffer like: TCHAR szBuffer[40] = TEXT("Line : %d, X : %d, Y : %d", i, x, y); Then it gives warning here. How do I remove this warning Message? What is wrong with it? What are the actual parameters of TEXT? Anny suggestions... Thanks, I can survive anything ... even NUKES!!!

You don''t seem to need that strcpy line at all. The wsprintf does exactly what it seems you want the strcpy to do.

TEXT() only takes one parameter, you''re passing it 4, so it''s ignoring the remaining 3.

You've put too much into the TEXT macro - and that's not how to use strcpy. Try this instead:


wsprintf(szBuffer,
 TEXT("Line : %d X : %d Y : %d"),
 i, x, y);

What are the actual parameters of TEXT?

TEXT is a macro that prepends an "L" to the string when UNICODE is defined - thus making the string UNICODE. It does nothing when UNICODE is not defined


#ifdef UNICODE
#define TEXT(quote) L##quote
#else
#define TEXT(quote) quote
#endif

I know that TEXT takes one parameter. But, value returned by wsprintf() is integer.

I have to use

"Line : %d, X : %d, Y : %d",i, x, y

to be displayed on the Window at various place.

Its value must be stored in a string.

Any suggestions?

or any other way to accomplish this task?

P.S. Its not an error. It''s a waning message. My application does what it needs to do, but I don''t want that warning message

Please help!!!
