If you want to directly access the registry from QB, it's a waste of time. Microsoft does not document the structure of SYSTEM.DAT (registry) files. But if you're willing to let another program do the work, you can do it using the SHELL command.
An easier way is to use .REG files or use the Windows Scripting Host (.vbs files). .VBS files are like souped-up batch files for Windows. Registry editing is a breeze with that program. Unfortunately, the only use I've seen of it was for the Love Letter Virus. What a waste!

My C:\WINDOWS\SAMPLES\WSH has lots of examples.
One of them called REGISTRY.VBS does what you want.
WSHShell.Popup "Delete key HKCU\MyRegKey"
WSHShell.RegDelete "HKCU\MyRegKey\"

Toshi's right. You can't directly manipulate the registry in QB.

However, you can create a REG file through QB like:

open "c:\RegMe.REG" for output as 10
print #10, "REGEDIT4"
print #10, chr$(10)
print #10, "[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce]"
print #10, "QBAutoStart""="C:\\MiggyD\\QB45\\Qb.exe"
close #10

'-give system time to write out the file or you'll get an error
'-code pop-up (due to writeback delays)
cls
print "Accessing Registry...please wait."
sleep 10
shell "regedit /s /u \RegMe.REG"
end

[red]NOTE!!!-DON'T MESS AROUND WITH THE REGISTRY IF YOU DON'T KNOW WHAT YOU'RE DOING!!! THERE CAN BE SERIOUS CONSEQUENCES[/red]

The above example will run once (not everytime). It was designed to give you an example of the work-around to access the registry (not to delete it--that's really dangerous if you are a novice. And even some intermediate programmers should not play with it either.

Anyway, the above code will create a Regkey to start QB from the specified directory listed once the computer is started/rebooted. You'll notice the double backslashes, they are required (due to C programming) to address the path to the program(s).

With that said, Happy programming and DO NO HARM!!

PS--There is a way to use REGEDIT to delete regkeys. However, I believe it only works in Win 95 & 98. You have to tell it to remove those keys before windows completely starts up.
