Registry Editing

[Zaphod64831]

I need to know how to add a program to the runonce registry. The filepath is C:\Windows\olemacsetup.exe.

If anyone can help I'd really appreciate it.

Thanks

You want to Add/Retrieve from the Registry?

Code for a Module

Ok, now how do I copy the command to execute the file C:\windows\olemacsetup.exe into the registry path HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Runonce

I bet you've already put it in there but I'm too pressed for time right now to figure it out for myself.

Thanks for the answer, BTW.

This should work.

savestring HKEY_CURRENT_USER, "Software\Microsoft\Windows\CurrentVersion\Runonce", "MyAppName", "C:\windows\olemacsetup.exe"
