How to use regular expressions to find all msgboxes without a title in visual studio

Hi all,

I have a very large solution in Visual Studio with over 13k msgboxes. Some of these will have message boxes (done over the years) that do not have the Title part (see eg 1). We are trying to correct all these (like eg 2) in order to display the same title consistently.

example:
1) msgbox("some text in here")
2) msgbox("some text in here",MsgBoxStyle.Exclamation, SomeGlobalVariable)

The buttons can vary.
I want to find all those msgboxes that have "msgbox(" + any characters apart from comma + ")"


Thank you in advance
Tony

What I have tried:

I have tried using [^,] to exclude commas but to no avail.
Any help would be greatly appreciated.
