So we have to use "" if we want " in VB string.
I wonder if there is a regular expression pattern which will match VB string?.

The project I'm working on is a Multichoice RadioButton quiz with answers and percentintegers. At the end there is a MsgBox that gives the number of answers counted 'correct'and the percent 'correct'. Also after you press the confirm button on that MsgBox it emails the results to the built in information given on the SMTP information. What I am trying to do now is show the input typed into the textbox on FormA in the MsgBox at the very end.

View 1 RepliesI am receiving this error message: "Input string was not in a correct format." on my ASP.net 2.0 VB project.
When looking at other posts with this error its obvious that each time it will be specific to the users' project. Therefore my main question is, is it possible to generate a more informative error message?
I am already in debug mode but it does not tell me in which string the problem lies. I am converting some strings to integers with "Cint" and have also tried the Integer.Parse() method to no avail.
var queryString = string.Format("filename={0}&filestream={1}&append={2)", fileName, Convert.ToBase64String(b, 0, bytesRead).ToString(), 1);
above line of code giving error 'Input string was not in a correct format.'

This is the String:
Quote:
<a title="I Need this String" href="/page/view_7894135/I_Need_This_String.html" class="tinylink">I Need this String</a>
This was my RegEx but it doesent work. I tried everything:
(?<=title="">).+(?="")
the string ordering does not matter Z, X, or c can be any order in the string but the regex must fail if all three are not present. I can easily do Three different regex but was wonder can this be done with one expression?

I'm trying to find a pattern in a string, I guess is very easy but I'm terrible in regular expressions. I have a big text and I need to find all the next type of pattern:
{a|b|c}
That can be also something like this: {a|b|c|s|f|f|ft|r} or any number of items inside but at least 2 items so the pipe symbol is another key. Is this an easy regular expression? I'm using vb.net 2005.
