set permission for each user

[chris1990]

If you follow this link you will find the code i have to change the permissions of a registry key.
http://www.vbforums.com/showthread.php?t=452607

I would like to know how to put it through a loop for every user. I have a code to get a list of usernames in to a list box. I just need to know how to loop it.

Thanks in advance Chris1990

[Al42]

Dim i As Integer
  For i = 0 To List1.ListCount - 1
    'run your code here
    'the username is List1.List(i) each time through the loop
  Next i

[chris1990]

Dim i As Integer
  For i = 0 To List1.ListCount - 1
    'run your code here
    'the username is List1.List(i) each time through the loop
  Next i

I have this code


run your code here
'the username is List1.List(i) each time through the loop
the code i need is the code to replace this

What ? Haven't you finished this yet ? . You need to pass the HKEY, subkey and users names to "UpdatePermissionsOfHKLM".

This following is an adaptation from the "SetPerm.bas" module. I've removed the unnecessary stuff to make it clearer, and changed the name of the procedure from "UpdatePermissionsOfHKLM" to "ChangeSubKeyPermissions", and added the necessary parameters so it can be called in a loop.

It's a lot of code, so spans the next few posts. You simply call "ChangeSubKeyPermissions", passing the parameters as required. "strUser" is, obviously, the user name.

EDIT: I've ripped this from an app I made, so one or more declarations (such as "RegCloseKey") or constants may be missing from the code - you will have to add them yourself. Make sure "Break On Unhandled Errors" is selected.

I have this code


run your code here
'the username is List1.List(i) each time through the loop
the code i need is the code to replace this

You said

I would like to know how to put it through a loop for every user. I have a code to get a list of usernames in to a list box. I just need to know how to loop it.

That's the code I gave you - to loop through the list of usernames.

[schoolbusdriver]

Just to re-iterate what Al42 said, and clarify my own posts WRT the above code: (the call to "ChangeSubKeyPermissions" is in post #4)

Dim i As Integer
   
For i = 0 To List1.ListCount - 1
   ChangeSubKeyPermissions HKEY_LOCAL_MACHINE, "Software\MY APPS\" & App.EXEName, List1.List(i)
Next i

Please could you edit your posts and use the code tags not the vbcode tags. As when copying and pasting the code i have to go through all the code and press enter in places.

By the way i did use it last time, i just need it automated now though. Thanks

thanks this works great , although there is a problem instead of setting permissions it removes the ticks from the allow and deny checkboxes. Will i still be able to read and write to the key.

Take a look at http://msdn2.microsoft.com/en-us/lib...7t(VS.80).aspx

In particular:

Checked ListBox
In Visual Basic 6.0, the Style property of a ListBox control determines whether a check box is displayed next to each text item. Multiple items in the ListBox can be selected by selecting the check box beside them even if the MultiSelect property is set to False. There is no way to programmatically determine the checked state of an item; if you required this capability, you have to use a ListView control instead.

May I suggest you change to a ListView control instead ? . The page has some VB6 ListView examples you may find useful such as:-

Code Changes for Determining Checked Items in a CheckedListBox Control

Despite the wording, the VB6 example refers to a ListView.
