Did you try it out? It displays a message box that shows the length of strResults in characters. E.g., if strResults contained "Imar" it would show "4 character(s)".
BTW: no need to quote the entire message when replying.

"Strings")
At the last of the line why we are using "Strings" because it is not displayed.
thanks

That's what I meant with " which part of it do you not understand". The clearer your question is, the better the answer.
Take a look at the intelliSense list in Visual Studio for the second parameter. It'll say its the Caption which is used as the title of the Message Box that pops up.
Second attempt: if you reply, can you please not quote the entire previous message?

kulfi, I too am new to vb2010. I used vb6 for years. LOve it Miss it but see the need to mover on. not sure but I think you might be looking a t the wrong command. the msgBox.show() command displays information about the msgBOx Command. if you are trying to simply display a msgBox on an application try using msgbox command like this...
msgBOx ("This IS What I wanted to display in the first place")
or the msgbox can return a value to you like...
ires = msgBox("do you want to continue?",vbYesNoCancel,vbDefaultButton2,"Title")
hope this helps

While MsgBox certainly works, I would focus on MessageBox.Show instead, especially if you have no background in versions of VB prior to .NET. MsgBox was ported over to the .NET framework VB compatibility layer to make the transition from VB 6 to .NET easier, but IMO, MessageBox.Show is closer to how everything else in the .NET Framework works and thus easier to understand and use in the long run.
Cheers,
Imar
