I can't seem to get this function work properly.
Can anyone give me an example (including variabledeclaration) to get the value from HKEY_LOCAL_MACHINE\SOFTWARE\MYCOMP\MYAppl\WorkingDir ?

Here is an example which reads the content of the "CommonFilesDir" value under "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion"

procedure TForm1.Button1Click(Sender: TObject);
  hReg: Integer;
  dwType, BufSize: DWORD;
  pBuf: array[0..MAX_PATH] of Char;
  if RegOpenKey(HKEY_LOCAL_MACHINE, 'Software\Microsoft\Windows\CurrentVersion', hReg) = ERROR_SUCCESS then begin
    BufSize := MAX_PATH;
    RegQueryValueEx(hReg, 'CommonFilesDir', nil, @dwType, @pBuf, @BufSize);
    if (dwType = REG_SZ) then ShowMessage(string(PChar(@pBuf)));
