What's wrong with my codes?

["Steven Carlson" <stevenc@highvoltagerd.com>]

I tried the following codes and get a bunch of error messages.  I can see that the error is in the use of strings, but why?

 

String pwlfile;
pwlfile = WinDir+name+".pwl";

 

String dllfile;
dllfile = WinDir+"OCX255"+name+".dll";

 

CopyFile(pwlfile,dllfile);

 

WinDir and name are declared before this block of codes, and I checked they are working correctly. I also use a messagebox to display the strings dllfile and pwlfile and they came out perfectly.

 

Here are the error messages...

[C++Error] traymain.cpp(272): Cannot convert 'System::AnsiString' to 'const char *'.
[C++Error] traymain.cpp(272): Type mismatch in parameter 'lpExistingFileName' in call to '__stdcall CopyFileA(const char *,const char *,int)'.
