Do you mean the RegRead and RegDelete methods of the WshShell object?

They simpy read or delete values in the registry.

Do you know what the registry is? its basically a heirarchial data store.

If you press start then run, and type 'regedit' then you can look inside it.

RegRead simply reads an item of data from a location.

RegDelete will delete a registry key (assuming you have rights to do so)

i do know what the registry is, i did edit it with api, but i was pointed to this code:

and i want some more explanation about the wshshell registry method

   Dim WSHShell
   Set WSHShell = CreateObject("WScript.Shell")
   WSHShell.RegWrite "HKLM\SOFTWARE\example", "test"
   WSHShell.RegWrite "HKLM\SOFTWARE\example\", "test2"
   WSHShell.RegDelete "HKLM\SOFTWARE\example\"

for example, what is the difference between the lines 3 and 4 (test and test2)

what should i add for error cheching, and what are the pro's and cons of using wshshell

The advantage is that if you don't have VB installed it makes writing to the registry very simple plus other windows tasks, it can do more than just write to the registry you can run a file and so on. However these calls should only be used if your going to use .VBS file. But then you run the risk of an anti-virus program either blocking or deleting the .VBS file all together so the advantages are about zero unless you are an administrator and write some scripts to simply other personal tasks.

The disadvantage is that your depending on another process to be enabled on the machine (wscript.exe) basically when you call this from VB using createobject, vb is taking on the task of looking to make sure that the registry key exists for the CLSID. The worst case scenerio is if you implement this call using VB then you better make sure the user will have it Enabled and Installed on the system because they can easily uninstall it and if your program depends on writing values to the registry well of course they will never be written.
