So let me get this right - you've posted two jobs to this forum, with your email address. No sign you've tried to do any of this yourself, are you really hoping someone will take the time to write all this and email it to you ?

What version of .NET are you using ? .NET 2.0 has a wizard control. As for parsing a web site, there's articles on how to do that. Putting a web site into your app is trivial.

i need to send mail in my vb.net project but it need to have the same interface of outlook compose

Perhaps there's only one for ASP.NET. No matter. Just create your wizard pages as controls and write a control which contains them and shows them one at a time.

No - that's not what the forums are for. If you registered with this email, the forum will mail you.

You mean it should look entirely like outlook ? There are some controls about on this site and others that emulate parts of the outlook UI. You're going to have to find them, or buy a library and make the UI yourself. Sending the mail itself is trivial, as I'm sure you are aware.

Using Math.Sqrt in Regex

I need the value in "\d*" to replace the "5". Is there an easy way to move that value over there?

Equation = Regex.Replace(Equation, "sqrt\d*", CStr(Math.Sqrt(5)), RegexOptions.IgnoreCase)

No - regex doesn't have math operators. You'll need to find the values you're after ( probably still with a regex, just use grouping to extract the number ), then use the replace method on the string to replace them after you have the square roots you want.

You can use a delegate to do anything you like with the value. I haven't tested this code, but it should be pretty close:

Regex.Replace(Equation, "sqrt\d+", delegate(Match match) { return Math.Sqrt(double.Parse(match.Value.SubString(4))).ToString(); } );

I changed the \d* to \d+ in the pattern by the way. I don't think that the keyword sqrt followed by zero digits is that useful... Smile | :)

Thanks for the code! Visual studio has "delegate" underlined in blue and says "Expression expected". I don't really know that much about them, so Im reading up on it now.

Right, the code is C# syntax. Sorry, I didn't check what message board it was. The VB.NET syntax would be a bit different. Perhaps you have to use a named method instead of an anonymous method.

Someone posted this code on another forum. It seems to work pretty well.

Dim Equation As String = "4+sqrt25"
Dim Matches As System.Text.RegularExpressions.MatchCollection = _
System.Text.RegularExpressions.Regex.Matches(Equation, "sqrt(?<number>\d*)")
For Each Match As System.Text.RegularExpressions.Match In Matches
Dim MyDbl As Double = Math.Sqrt(CDbl(Match.Groups("number").Value))
Equation = Equation.Substring(0, Match.Index) & MyDbl.ToString & _
Equation.Substring(Match.Index + Match.Length)
Next
MessageBox.Show(Equation.ToString)

It works for a single value, but with more than one value the position in the Match objects will not match the string any more.

If you for example have the string "1+sqrt25+sqrt16+123456", you will get two matches at position 2 and 9. The first match will correctly be replaced so that the string contains "1+5+sqrt16+123456", but now the match at position 9 will no longer match the contents of the string. The second replace will replace "6+1234" instead of "sqrt16", so the final result is "1+5+sqrt1456" instead of "1+5+4+123456".

Looping through the matches in reverse order would work, though, or putting the result in a separate string.
