Hi,

I haven't used VDS on XP or Windows 2003 server. I created a small app for 2003 server and am getting error messages. Is there a compatilbity problem with VDS V4.0 and 2003 server? Is there a special way that the dll needs to be registered to work with 2003?

Has anyone out there used this version with 2003 yet and not encountered problems?

Is V 5.0 better on 2003?

THanks for taking the time with this.

Regards,

BIll

I can report that I use VDS 5 apps on a Server 2003 machine every day and they work very well.

FYI

w_marquardt777,

What are the error messages being returned? Are you using any external dlls?

It's a while ago, but when I took over the VDS 4 code in order to develop VDS 5 I seem to recall that the registry access code requested read/write access even to read the registry. This is a problem that VDS inherited from Delphi. I fixed the problem in the runtime for VDS 5, but it means that there is going to be a problem for VDS 4 and earlier apps that run under a restricted account on any NT family operating system, if they access the registry.

I run VDS 5 apps on my company web server running Server 2003 with no problems whatever.

When the program didn't work out, I was out of time and didn't record the errors.

I'll be back at the clients today and get the accurate error message.

It's encouraging that people are having success with VDS on 2003. Maybe I just have something wrong with the *.exe.

More soon.

THanks,

Hi Jules,

I don't think it's really a bug in VDS or DELPHI. The permissions on Windows accounts can limit certain user accounts to what can be accessed via the registry, especially the HKEY_LOCAL root. To access those registry entries with an account with limited priviledges you can use this in delphi:

You forget that the VDS runtime is developed using Delphi 2. The Delphi 2 Registry object doesn't have an Access property, and the OpenKey method requires all access. Perhaps it can't be called a bug in Delphi 2, since I'm not sure whether Windows NT existed at the time it came out, but it is certainly a problem for any program created using earlier versions of Delphi that run on NT based operating systems.

Actually, I wasn't aware that the Access property existed. VDS 5 uses a new method cribbed from the Delphi 6 runtime code called OpenKeyReadOnly.
