Josmic,

Sorry because of my delayed answer, I was busy with other matters recently.

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer is a registry location and you can't use it directly within VB, so you have to write a sub/function to update this location with the specific value, anyway don't bother your self about the function here it is.

1- Add form1 to project1.
2- Add command1, command2, command3 and command4 to form1.
3- Paste the following code:

Private Const HKEY_CURRENT_USER = &H80000001
Private Const REG_DWORD = 4&
Private Const KEY_ALL_ACCESS = &H3F

Private Declare Function RegOpenKeyEx Lib "advapi32.dll" Alias "RegOpenKeyExA" _
(ByVal hKey As Long, ByVal lpSubKey As String, ByVal ulOptions As Long, _
ByVal samDesired As Long, phkResult As Long) As Long

Private Declare Function RegSetValueExLong Lib "advapi32.dll" Alias "RegSetValueExA" _
(ByVal hKey As Long, ByVal lpValueName As String, ByVal Reserved As Long, _
ByVal dwType As Long, lpValue As Long, ByVal cbData As Long) As Long

Function SetValueEx(KeyName, ValueName As String, Value As Variant) As Long
 Dim hKey As Long
 Dim lValue As Long
   
 lValue = Value
 Call RegOpenKeyEx(HKEY_CURRENT_USER, KeyName, 0, KEY_ALL_ACCESS, hKey)
 SetValueEx = RegSetValueExLong(hKey, ValueName, 0, REG_DWORD, lValue, 4)
End Function

Private Sub Command1_Click()
 'To Enable the Desktop/Explorer's context menu
 Call SetValueEx("Software\Microsoft\Windows\CurrentVersion\Policies\Explorer", "NoViewContextMenu", 1)
End Sub

Private Sub Command2_Click()
 'To Disable the Desktop/Explorer's context menu
 Call SetValueEx("Software\Microsoft\Windows\CurrentVersion\Policies\Explorer", "NoViewContextMenu", 0)
End Sub

Private Sub Command3_Click()
 'To Enable the Start/Tray's context menu
 Call SetValueEx("Software\Microsoft\Windows\CurrentVersion\Policies\Explorer", "NoTrayContextMenu", 1)
End Sub

Private Sub Command4_Click()
 'To Disable the Start/Tray's context menu
 Call SetValueEx("Software\Microsoft\Windows\CurrentVersion\Policies\Explorer", "NoTrayContextMenu", 0)
End Sub

NOTE: Disabling the context menu will be effected immediately but to enable it you must restart windows to take the effect.


Best regards

josmic,

The code above is doing the following:
1- Enable/Disable right-mouse click on the Desktop window.
2- Enable/Disable right-mouse click on the Explorer window.
3- Enable/Disable right-mouse click on the Taskbar.
4- Enable/Disable right-mouse click on the Start button.

If you face any kind of error please post it, and don't hesitate to ask if you need more clarification.

I'm sorry josmic, I didn't test it on Windows98 yet.

It is working fine with Windows95 and WindowsNT.

bin, thanks for the help. I will repost this question. I
am going to give you these points anyway.
1) Since your online now perhaps you know how to disable the start button (bottom left on the taskbar)  -without-  disabling the taskbar or hidding the taskbar. I dont care if the start button is visible or not.
2) or im having problems with a webbrowser control. my back and forw buttons dont remember more than the verylast or the verynext
Im using webbrowser.GoBack and frw, I've seen somewhere in here
a refference to code with history list box  etc instead of
back and forw and I think you answered it.?

Ive been picking up code here and have not run into a win98
problem yet. Again thanks.
