I'm using multiple windows dirs (C:\windows, E:\Winnt, F:\Win95US) and use a program which needs to install a picture in their root. my code I use now is as follows;

Image1.Picture.Bitmap.Handle := NViewLibLoad('e:\winnt\800x600.jpg', False);

I tried using this suggested in the help file : NViewLibLoad('<systemroot>\800x600.jpg', False); but this does not work.

how does it work so the program automatically searches the root Windir of the active windows (systemroot).

You can use the GetWindowsDirectory API call to get the current path to the Windows directory.  The <systemroot> label that you are attempting to use appears similiar to some of the directory labels supported by InstallShield and other installation packages.  You can also get the path to the current Windows System directory with the GetSystemDirectory call.

Using these calls are simple with Delphi.  The following code can be used:

Var
  WinDirLen: Integer;
  WinDir: PChar;
Begin
  GetMem(WinDir, 255);
  WinDirLen := GetSystemDirectory(WinDir,255);
  { Process SysDir as required perhaps just to copy to a }
  { for later processing so the memory can be dealloc'ed }
  FreeMem(WinDir);
End;

The Delphi help system contains additional information that will be useful for calling these functions.
