Hi everyone.

This one may be a stickler.

I downloaded some sample source code from MSDN from the below link:

http://msdn.microsoft.com/library/en...asp?frame=true

The project 'BandObjs' is a simple example that demonstrates the implementation of the three types of band objects. These are Desk Bands, Explorer Bars and Communication Bands.

In the source code 'BandObjs.cpp' I encountered the following line:

(Toggle Plain Text)

hr = StringCchPrintfEx(szSubKey,                   
                       MAX_PATH,                   
                       ClsidEntries[i].szSubKey,  
                       szCLSID);

When I first compiled the project I got the following error:

error C2065: 'StringCchPrintfEx' : undeclared identifier.

So, since it wasn't included in the download I was able to find it in my Microsoft SDK\Include\strsafe.h file. So, I included this file in the project and recompiled it. After that I get the following error:

error C2660: 'StringCchPrintfExA' : function does not take 4 parameters

The definition of the function is given below:

(Toggle Plain Text)

STRSAFEAPI StringCchPrintfExA(char* pszDest,
                              size_t cchDest, 
                              char** ppszDestEnd, 
                              size_t* pcchRemaining, 
                              unsigned long dwFlags, 
                              const char* pszFormat, ...)

From what I can gather from reading the 'strsafe.h' file about the function it is a replacement for the 'sprintf()' function. As you can see the function takes 6 parameters while the implementation of it is only passes 4 parameters. I tried using NULLs as the last two parameters but that didn't work. I just got another compiler error message.

The problem that I am up against is that I don't know how to make it work. Does anyone know what I can do to the code so that I can get the desired results, either by changing the function definition or changing the function implementation?
