Enumerate uninstall registry key to get displayname & displayversionvalue

Hey, I am trying to enumerate the

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

registry key and check the displayname & displayversion registry value for all the sub keys under the uninstall key then compare the displayname & displayversion value with a if statement.

For example if one of the the displayname = "Adobe Flash Player 10 ActiveX" & displayversion = "10.1.82.76" then textbox.text = "Your adobe flash is up to date"


This is the code I been using to check a specific registry value to see if quicktime 7.67.75.0 is installed i figured it would be best to enumerate the subkeys and check the displayname & displayversion because im checking like 6 programs to see if the version is current.

Dim quicktime As String
quicktime = My.Computer.Registry.GetValue _
("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{EB900AF8-CC61-4E15-871B-98D1EA3E8025}", "DisplayVersion", Nothing)
quicktime = (quicktime)

If quicktime = "7.67.75.0" Then quicktime1.Text = " Quicktime 7.67.75.0 is installed" Else quicktime1.Text = " Quicktime 7.67.75.0 is not installed"

If quicktime = "7.67.75.0" Then quicktime1.ForeColor = Color.Green Else quicktime1.ForeColor = Color.Red


I'm new to VB any help would be great!!!

Im using vb 08

I don't think that's the best way to do it. Plus, it's just as easy to tell you how to REMOVE programs, which would be against the AUP, in my estimation.

You can check the version thats running, as well. In task manager...

Im not trying to uninstall programs. i'm trying to check the version then display the version in a text box so a user can run the program to see if their software needs updated.

This site still exists, but the link changed. This enumerates the registry, but doesn't do much else, but enumerate the data keys, then the value keys.
