the problem really is Vista - it changed all programs to run at a User Level -
it's easy enough to change - may not be the best way (at least in M$'s eyes)
right click on the desktop shortcut icon and change it to "Run as Administrator"

Subject: [advanced_delphi] Re-Writing for Vista
Hi All,
I have just gotten the first glitches with Vista from users and it
involves the logic for writing to the databases and indexs. I'm still
of the old DOS mindset and a self-taught programmer. I have all my
files located under the main folder where the program is installed and
using Inno-Setup, I have the user install to:
c:\program files\myprogram
Using Delphi 5, I can determine if the user has installed the program
somewhere else by determining where the EXE is located using this code:
exepath:=ExtractFilePath(Application.ExeName);
datapath := exepath + 'data\';
if not DirectoryExists(datapath) then
if not CreateDir(datapath) then begin
raise Exception.Create('Cannot create '+ datapath);
exit;
end;
mdxpath := exepath + 'indexs\';
if not DirectoryExists(mdxpath) then
if not CreateDir(mdxpath) then begin
raise Exception.Create('Cannot create '+ mdxpath);
exit;
end;
Under Vista, I understand that this is a NO-NO since it requires write
permission from the Administer. Now my Users are all individual HOME
users, who are the Admins and don't know how to set-up their pc's to run
the program they way it did under all previous versions of Windows.
I'm at a loss, since I don't have a PC with Vista. Soon to be rectified
before I go nuts trying to answer questions from my users!
Meanwhile, how should I re-write my programs? Where can I write from the
program so that the user doesn't need Admin privileges and how do I
determine the folder name?
