Writing C++ plugins for C4D, how do you format a string?
I want to do this:

"The file %1 exists, do you want to overwrite?", dialogFileName.GetFileString()

But haven't found a way to do it in C++.

Take a look at MessageDialog() - there are several overrides. But to do this you will need to use a resource string (good practice anyway). Of course, it's only good for short messages, but that's often all that's needed.

There are a couple of ways to do this.

Here is the first one.

  
  String = "The file " + dialogFileName.GetFileString() + " exists, do you want to overwrite?";

Another way is to use something like snprintf() but it is not a C4D way to do this :)

  
    
    
      char buffer [128];
      int cx = snprintf ( buffer, 128, "The file %1 exists, do you want to overwrite?", str );

  
  //TODO:  Add better way to do this...

Bingo!
That's the one for me, thanks.

Yes, I always use resource strings.
Great tip! Just using the ID - fantastic.

Here's a quick-n-dirty "printf()" type function - just make sure that you don't overflow the buffer :)...

  
//-------------------------------------------------------------  
// GePrintF()

void GePrintF(const CHAR *format,...)  
{  
 va_list arp;  
 CHAR buf[1024];  
  
 va_start(arp,format);  
 vsprintf(buf,format,arp);  
 GePrint(buf);  
 va_end(arp);  
}
