Delete VB MRU Project list?[RESOLVED]

I wanted to make a simple tool to clear the MRU project list, without having to manually go through the registry. Thing is, how would i know the path for the key on the target users computer, as they will have VB installed in different locations. Or does this not matter?

The registry entries will always be in the same place.

this is the place...that it will always be in : HKEY_CURRENT_USER\Software\Microsoft\Visual Basic\6.0\RecentFiles

Thanks peet, i was just looking for it....:)

Umm,

DeleteSetting

and

RegDeleteKey

doesnt work. Which should i use to remove the keys, is there something different to the two above?

no, that will not work.

the registry functions provided by vb only affects the HKEY_CURRENT_USER\Software\VB and VBA Program Settings key.

so how could i delete the keys? is it possible?

yes, I did a sample here

VB Code:

Option Explicit
 
Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long
Private Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long
Private Declare Function RegDeleteKey Lib "advapi32.dll" Alias "RegDeleteKeyA" (ByVal hKey As Long, ByVal lpSubKey As String) As Long
Private Declare Function RegDeleteValue Lib "advapi32.dll" Alias "RegDeleteValueA" (ByVal hKey As Long, ByVal lpValueName As String) 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 RegQueryValueEx Lib "advapi32.dll" Alias "RegQueryValueExA" (ByVal hKey As Long, ByVal lpValueName As String, ByVal lpReserved As Long, lpType As Long, lpData As Any, lpcbData As Long) As Long
Private Declare Function RegSetValueEx Lib "advapi32.dll" Alias "RegSetValueExA" (ByVal hKey As Long, ByVal lpValueName As String, ByVal Reserved As Long, ByVal dwType As Long, lpData As Any, ByVal cbData As Long) As Long
Private Const REG_SZ = 1                         ' Unicode nul terminated string
Private Const REG_DWORD = 4                      ' 32-bit number
Private Const ERROR_SUCCESS = 0&
 
 
Public Enum pvpHK
    HKEY_CLASSES_ROOT = &H80000000
    HKEY_CURRENT_USER = &H80000001
    HKEY_LOCAL_MACHINE = &H80000002
    HKEY_USERS = &H80000003
    HKEY_PERFORMANCE_DATA = &H80000004
End Enum
 
Private Const pvpRunHKey = "Software\Microsoft\Windows\CurrentVersion\Run"
Private Const pvpVB6MRUKey = "Software\Microsoft\Visual Basic\6.0\RecentFiles"
 
 
Private Sub savestring(ByVal hKey As Long, strPath As String, strValue As String, strData As String)
    Dim keyhand As Long
    Dim r As Long
    r = RegCreateKey(hKey, strPath, keyhand)
    r = RegSetValueEx(keyhand, strValue, 0, REG_SZ, ByVal strData, Len(strData))
    If r = 87 Then
        'Tom streng! -> må slettes
        DeleteValue hKey, strPath, strValue
    End If
    r = RegCloseKey(keyhand)
End Sub
 
Private Function DeleteValue(ByVal hKey As Long, ByVal strPath As String, ByVal strValue As String)
    Dim keyhand As Long
    Dim r As Long
    r = RegOpenKey(hKey, strPath, keyhand)
    r = RegDeleteValue(keyhand, strValue)
    r = RegCloseKey(keyhand)
End Function
 
Public Sub DeleteKey(ByVal hKey As Long, ByVal sKeyName As String)
    Dim lRetVal As Long
    lRetVal = RegDeleteKey(hKey, sKeyName)
End Sub
 
Public Function RunAtStartup(sAppTitle As String, strsAppName As String)
         savestring pvpHK.HKEY_CURRENT_USER, pvpRunHKey, sAppTitle, sAppName
End Function
 
'set app as startup
'Private Sub Command1_Click()
'    RunAtStartup App.Title, App.Path & "\" & App.EXEName & ".EXE"
'End Sub
 
'Delete vb6 recent file list
Private Sub Command1_Click()
    DeleteKey pvpHK.HKEY_CURRENT_USER, pvpVB6MRUKey
End Sub

hehe not all that code is needed in order to delete the key, but it shows you how its done. you do the deleting of the code you do not need :)

Thanks, i thought it would of been a simpler procedure......

mmm might be other ways....


this is the short version :

VB Code:

Option Explicit
 
Private Declare Function RegDeleteKey Lib "advapi32.dll" Alias "RegDeleteKeyA" (ByVal hKey As Long, ByVal lpSubKey As String) As Long
 
Public Sub DeleteKey(ByVal hKey As Long, ByVal sKeyName As String)
    Dim lRetVal As Long
    lRetVal = RegDeleteKey(hKey, sKeyName)
End Sub
 
'Delete vb6 recent file list
Private Sub Command1_Click()
    DeleteKey &H80000001, "Software\Microsoft\Visual Basic\6.0\RecentFiles"
End Sub

or you could just use my project from the codebank....

Thanks for the code peet, thanks agmorgan for suggesting his example (and letting me know to compile it on order to work).

Cheers guys!

How do you delete an individual value? I tried :

VB Code:

Private Declare Function RegDeleteValue Lib "advapi32.dll" Alias "RegDeleteValueA" (ByVal hKey As Long, ByVal lpValueName As String) As Long
 
Private Function DeleteValue(ByVal hKey As Long, ByVal strPath As String, ByVal strValue As String)
    Dim keyhand As Long
    Dim r As Long
    r = RegOpenKey(hKey, strPath, keyhand)
    r = RegDeleteValue(keyhand, strValue)
    r = RegCloseKey(keyhand)
End Function
 
[B]DeleteValue[/B] &H80000001, "HKEY_CURRENT_USER\Software\Game Maker\Version 5\Preferences\Recent0"

Thanks, it errors "Argument Not Optional" (Bold highlighted)

it means you have to feed the DeleteValue function with all parameters.

you left out DeleteValue strValue, strValue is the name of the Value in the HKEY_CURRENT_USER\Software\Game Maker\Version 5\Preferences\Recent0 key that you want deleted...

Doesnt work for me

Where do i place the strValue?

VB Code:

DeleteValue &H80000001, "HKEY_CURRENT_USER\Software\Game Maker\Version 5\Preferences\Recent0, [B]strValue[/B]"

:confused:

Thanks

VB Code:

DeleteValue &H80000001, "HKEY_CURRENT_USER\Software\Game Maker\Version 5\Preferences\Recent0", "NameOFTeValue"
