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

Re: Enumerate uninstall registry key to get displayname & displayversionvalue
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.

Re: Enumerate uninstall registry key to get displayname & displayversionvalue
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.
Code:
Const ERROR_NO_MORE_ITEMS = 259&
Const HKEY_CURRENT_CONFIG = &H80000005
Const HKEY_LOCAL_MACHINE = &H80000002
Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long
Private Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long
Private Declare Function RegEnumKeyEx Lib "advapi32.dll" Alias "RegEnumKeyExA" (ByVal hKey As Long, ByVal dwIndex As Long, ByVal lpName As String, lpcbName As Long, ByVal lpReserved As Long, ByVal lpClass As String, lpcbClass As Long, lpftLastWriteTime As Any) As Long
Private Declare Function RegEnumValue Lib "advapi32.dll" Alias "RegEnumValueA" (ByVal hKey As Long, ByVal dwIndex As Long, ByVal lpValueName As String, lpcbValueName As Long, ByVal lpReserved As Long, lpType As Long, lpData As Any, lpcbData As Long) As Long
Private Sub Form_Load()
'KPD-Team 2001
'URL: http://www.allapi.net/
'E-Mail: KPDTeam@Allapi.net
Dim hKey As Long, Cnt As Long, sName As String, sData As String, Ret As Long, RetData As Long
Const BUFFER_SIZE As Long = 255
'Set the forms graphics mode to persistent
Me.AutoRedraw = True
Me.Print "RegEnumKeyEx"
Ret = BUFFER_SIZE
'Open the registry key
If RegOpenKey(HKEY_LOCAL_MACHINE, "Hardware", hKey) = 0 Then
'Create a buffer
sName = Space(BUFFER_SIZE)
'Enumerate the keys
While RegEnumKeyEx(hKey, Cnt, sName, Ret, ByVal 0&, vbNullString, ByVal 0&, ByVal 0&) <> ERROR_NO_MORE_ITEMS
'Show the enumerated key
Me.Print " " + Left$(sName, Ret)
'prepare for the next key
Cnt = Cnt + 1
sName = Space(BUFFER_SIZE)
Ret = BUFFER_SIZE
Wend
'close the registry key
RegCloseKey hKey
Else
Me.Print " Error while calling RegOpenKey"
End If
Me.Print vbCrLf + "RegEnumValue"
Cnt = 0
'Open a registry key
If RegOpenKey(HKEY_LOCAL_MACHINE, "Software\Microsoft\Windows\CurrentVersion", hKey) = 0 Then
'initialize
sName = Space(BUFFER_SIZE)
sData = Space(BUFFER_SIZE)
Ret = BUFFER_SIZE
RetData = BUFFER_SIZE
'enumerate the values
While RegEnumValue(hKey, Cnt, sName, Ret, 0, ByVal 0&, ByVal sData, RetData) <> ERROR_NO_MORE_ITEMS
'show data
If RetData > 0 Then Me.Print " " + Left$(sName, Ret) + "=" + Left$(sData, RetData - 1)
'prepare for next value
Cnt = Cnt + 1
sName = Space(BUFFER_SIZE)
sData = Space(BUFFER_SIZE)
Ret = BUFFER_SIZE
RetData = BUFFER_SIZE
Wend
'Close the registry key
RegCloseKey hKey
Else
Me.Print " Error while calling RegOpenKey"
End If
End Sub
