Uninstall MDAC 2.7 And Windows Server 3
Jul 21, 2009
(I found no server 2003 forums so i posted here) I have recently been tasked with moving legacy applications (written in VB 6) that have to be migrated from windows server 2K to windows 2003. My superiors tell me that we MUST use MDAC 2.7 because the VB 6 applications are very old and use office 97 (no chance for upgrade because they will break - they will be supplanted by .net applications) Also, if these legacy apps use 2.8 they will break as well.
I know that Windows Server 2003 automatically comes with MDAC 2.8 and there is no way to uninstall it (is there?). But is it possible to install MDAC 2.7 (parallel to 2.8) and force our applications to use the 2.7 version? Or do we have to stick with windows 2k if we HAVE to MDAC 2.7?

Have a VB.net application that installs initially from CD and then when the user gets into the internet the application updates. In order to better support problems with this application is has been suggested in the past to uninstall it and do a fresh re-install. However, in investigation it was determined that the uninstall does not consider all installed objects and does not uninstall the CD install.Can the uninstall functionality be modified to catch the other instances of this application and also uninstall them?

I'm kind of shooting in the dark here - searches don't seem to be productive on this. I want to create a .NET program to monitor the install and uninstall of fonts. If something is installed or uninstalled, I want to run a program to do something.
I thought maybe a Windows Service, but haven't gotten very far with figuring out how to monitor fonts. Is this the right way and if so, what am I overlooking? If not, is there a different way to do this?

I have a Deployment project which creates an MSI setup file to install a service. (VB .NET) I have a reference to another project which is a win form application and has a setup form which takes the user name, password and some other settings information which will be used by a service. It has "Finish" and "Cancel" buttons. I am creating a new instance of this form on Sub New() of the ProjectInstaller Class, so user can input information, click Finish and installation completes. The service is then automatically started. Now, when I click Cancel on the settings form, I am not able to exit out and halt the installation process. Instead it installs the service !! How can I use the Rollback or Uninstall methods to do the task? I was trying this -
On cancel_click, set boolean var cacelStatus = True
On Sub New() method of ProjectInstaller class, I am checking - If true - uninstall, else - install
How can I achieve this?

We are currently using Access 97 as our database. This resides on the remote farm server (which is a Windows 2008 R2 server). We are using a front end vb6 exe which accesses the back end data.Occasionally we are getting corruption to our database and we have to make sure everyone exits the software to allow us to repair/compact it. There are 2 physical servers, each running 2 virtual machines. When the user logs onto the farm using RDP, they go to one of these 4 virtual machines.We are getting all kinds of corruption, some where # characters have been inserted into the top of one table, some where the indexes are corrupted, and some where access needs to repair the database.

I am working on moving applications from Windows 2000 to new server Windows 2003 R2(64 Bit). I noticed that there are some VB programs and config files for those programs have been placed in Windows 2000 Registry. Some other applications are using them from different servers.Why do we use registry here? How can i move these to registry in windows 2003? Can I just move these or do I have to write VB programs to place them in 2003 registry?

I have a .net Windows Service developed in VB.net. I have a settings file in the root directory called Connections.XML and I am setting the basedirectory [code]...
When I schedule the service this is working absolutely fine in my Windows XP machine. But when I installed the same service in our development server (Windows 2003 64 bit Server) for some reason it is not able to locate this file.

I have a problem with scroll in a treeview in a Windows forms application (Framework version 3.5).
The strange thing about the problem is that on Windows XP, Windows 7 and Windows 2008 the scroll works as excepted, but in Windows Server 2003 SP2 the scrolling doesn't work. Enable/disable Visual Styles doesn't seem to make a difference on Server 2003.
Steps to reproduce the error:
1. Add a treeview to a form and add x nr of root items (and 1 sub item to each item).
2. Expand a number of nodes. The non-standard thing here is that we are changing the node integral height because we display a usercontrol with the treenode (See example of the code below).
3. When you scroll afterwards, you cannot scroll to the bottom node. The scrollbar is all the way down, but we are not seeing the last node.
Public Shared Sub SetNModeHeight(ByVal Node As TreeNode, ByVal IntegralHeight As Integer)
'Create instance of tvitemex structure.

We recently upgraded our job server to Windows Server 2008. We have jobs we run manually in a folder (c:Custom Programs). Some programs are console programs others are have a gui. This one program has a gui.It also has a progress bar that shows the progress of the job when you click the go button. Of course it spawns a thread to do the processing. This thread creates a log file to write errors and other things too.
The problem is when the program goes to create the log file an access not authorized error is thrown. I checked the permission on the folder. All users are allowed to create/edit/append/execute. Pretty much everything except take ownership. Also, there's nothing that denies anything. So I see no reason why this isn't working. We can get this to work by using the run as administrator option when we first run the program. However, we don't view this as unacceptable solution. My only thought is the spawned thread isn't getting the same permission set as the program. Am I correct or does something think it's something else.

I'm looking for any references on the best way to perform an unattended uninstall of a product using VB.NET. The product was installed using Windows Installer and the product name is Dell Kace Agent. I would like to perform the uninstall within the VB.NET code.Here's a VBScript that uninstalls a product using WMIC. This could be converted to VB.NET fairly easily, but is there a better way to perform a uninstall within VB.NET code than querying WMIC? I would rather not use WMIC to perform the uninstall maybe get the uninstall string from the registry?
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\" _

Since installing Windows 7 on one of my test machines my automated uninstaller can not find the uninstall string. My script works on XP just fine. I noticed that the uninstall information is in a different location for Windows 7. it is in Wow6432NodeMicrosoft... is there a constant I can use that will allow my script find the correct uninstall location on both Windows 7 and Windows XP?

I've taken MS 4994A (Intro to VB.net), and am studying for 4995A (Advanced Intro to VB.net)Previous experience with VB6 and C++ tells me that the way to do it would be to create a program that will accept a list of computer names and check the registry one-by-one (I'm open to suggestions, though, of course). If it finds the program we're wanting to remove, it will remove it, then automagically install .net 2.0 and the .net version of the programs that were just removed.

I have a project that creates and installs a window service. I want to uninstall it because it is running both on my PC and on another. I want to leave it on the other. So when I open VS with the project, I right-click on the servicesetup and choose uninstall and it says "This action is only valid for products that are currently installed." It is listed in control panel Services, so isn't it installed?

I have an application that contains an MDB. This application has a feature that will allow the user to update the database to a newer version that is on a thumb drive.The database ispart of the application and is not user-updatable, so it seems as though it should live in the Program Files directory with all the other data files (xml, etc.)However, somehow it found its way into the Virtualstore.Now when I go through my process to update the database via the application when I try to run the application is is re-routed to the old mdb in the virtualstore.
But much worse than that, I found out that the virtualstore for the application survives a reinstall Now to my mind this is a huge bug because one would expect when one uninstalls and re-install an application that would have created a "clean slate" and everything would work correctly. But here I have an instance where the user thinks she has installed a fresh copy of the application but in fact is getting corrupted by old junk in the virtual store from a previous install.
