I made this function for one of my apps. It allows you to get special
folder locations very easily.
This is untested because I had used a boost::scoped_array for the char
array.
AnsiString __fastcall GetSpecialPath(int Folder)
{
char *Path = new char[MAX_PATH];
AnsiString StrPath;
SHGetSpecialFolderPath(NULL, Path, Folder, 0);
StrPath = Path;
delete[] Path;
return StrPath;
}
For app data, call it like this :
GetSpecialPath(CSIDL_APPDATA)

You don't need to allocate the buffer on the heap. Use the stack instead.
This is also partly in case the assignment to the AnsiString throws an
exception. You are not currently protecting the buffer from exceptions, so
if one ever occurs then your buffer will be leaked.

You are not checking that SHGetSpecialFolderPath() is actually succeeding
before returning the buffer value.
Try this instead:
AnsiString __fastcall GetSpecialPath(int Folder)
{
char Path[MAX_PATH+1] = {0};
if( SHGetSpecialFolderPath(NULL, Path, Folder, 0) )
return AnsiString(Path);
return "";
}
