Search a String

[deoblo1]

Ok lets say I have a string composed of this text (including the quotes)

Hello "bob how are" you?

what would be the fastest way to search that string to see if it contains a " (quote marks)? I know i could use the mid instruction and put it in the middle of a loop and just check every char one at a time, but that is slow. I cant split the string because i want to keep the " not use it as the dilimiter. Does vb.net have a search function like c++? Because i have a feeling vb would have a built in function that is faster then anything i can write.

you could use InStr to check if the " is there.

The String object has an IndexOf method that returns the index of the first instance of the search string or -1 if non is found.

Dim test As String="Hello ""bob how are"" you?"
If test.IndexOf(ControlChars.Quote)=-1 Then Msgbox("Not Found")

I'm getting slow in my old age...

so i am guessing that is like the strcmp function in c++? It just returns a boolean true if it is there, or false if it is not there?

I think that may of solved my problem, now to attempt to write some fast code, thank you for your time and help.

the indexOf-function doesn't return True or False like your c++Function does. This fucntion returns the index of the string you're looking for int the base-string. When it returns -1, this means that the string is not found.
I wouldn'd adise to still use the instr-function. This is a VB6-function that is still suported, but it's better to use the .NET-function .IndexOf.
