Whats wrong with this line

Can anyone tell me what is wrong with the following line.

Code:

---

Process.Start("regedit", "/S Environ("%systemdrive%") &"\FixAVI.reg")

---

I get err with the "%" = Character is not valid.

Your double quotes are messed up. You can't just plop a double quote into a string because it's interpreted as the end of the string. If you want a double quote in a string you have to escape it, e.g.

vb.net Code:

Dim str As String = "He said ""Hello"" to me."

Look at the number of quotes you are providing...

[EDIT] - Jmchilhinney beat me to it as I was preparing a nice brightly coloured example of what was code and was string!

So how do I do that.

I just want to run REG file located at SystemRoot, but in silent mode

jmcilhinney gave you an example - just double up your quotes which form part of the string literal.
