Edit Registry Key 1

[visualJay]

I have a program that installs its sessions for setups in the registry.

I need to remove all the sessions but a couple to stop users from changing things.
and in the ones that are left i want to change the
"User" = ""
to
"User" = "logged in users name"

I want my program to do this because so i dont have to do it manually everytime i install the program on a new computer.

registry is like this

my computer\HKEY_CURRENT_USER\Software\"Company Name"\"Program"\session

all the keys reside here there are 14 keys here and i only need 2 of them so the users quit messing things up

can any one help

Check out RegDeleteKey and RegDeleteValue API calls. As the name imply, they delete key and value respectively.

Check out Knowledgebase for more info.

i have figured out how to read in a subkey values if i know that subkey name but i want to read in to a list the subkeys of

HKEY_CURRENT_USER\Software\"Company Name"\"Program"\sessions
that way i dont have to look in the registry to get them.

with these in the list and remove the ones i dont need and then alter the values in the remaining subkeys

Perhaps you might take a look at the RegEnumKeyEx API.
The RegEnumKeyEx function enumerates subkeys of the specified open registry key. Good Luck

regenumkeyex api where can i see how it is used.

Here is a snippet that you may find useful.

Const END_OF_KEYLIST = 259&
Const HKEY_CURRENT_USER = &H80000001

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

Dim lLng_KeyHandle As Long
Dim lStr_KeyBuff As String
Dim lLng_KeyLen As Long
Dim lInt_KeyCount As Integer

If RegOpenKey(HKEY_CURRENT_USER, &quot;<Your Main Key>&quot;, lLng_KeyHandle) = 0 Then
lLng_KeyLen = 255
lStr_KeyBuff = Space(lLng_KeyLen)
lInt_KeyCount = 0
Do While (RegEnumKeyEx(lLng_KeyHandle, lInt_KeyCount, lStr_KeyBuff, lLng_KeyLen, 0&, vbNullString, 0&, 0&) <> END_OF_KEYLIST)
Debug.Print Left(lStr_KeyBuff, lLng_KeyLen)
lInt_KeyCount = lInt_KeyCount + 1
lLng_KeyLen = 255
lStr_KeyBuff = Space(lLng_KeyLen)
Loop
End If

I am new to the registry stuff and the advanced stuff and i dont mean to be a pain.

but i dont full understand the above and it says something about the HKEY_CURRENT_USER when i try to compile.

 

[CajunCenturion]

You said in an earlier post that &quot;I have figured out how to read in a subkey values if i know that subkey name ...&quot; So you're definately doing something right. Perhaps you should post what code you have, and we can work on getting this additonal functionality integrated into what you already have.
Good Luck
