Steve,

You need to add an @ in the declare to tell it the string argument is passed by reference. Also the second argument tells the api how big the buffer is:

BOOL GetUserName(
  LPTSTR lpBuffer,  // address of name buffer
  LPDWORD nSize     // address of size of name buffer
);
 

declare GetUserName in win32api string @ sBuffer, integer @ nSize
UserName = space(25)
nSize = len( UserName )
GetUserName( @UserName, @nSize )
