I am developing an C# application to book the resource for meeting in outlook 2003 using C# 2010.

I am passing date and time as user input and check with the resource calendar, If there is no any item existing for the specified date and time then book the resource, otherwise just retun the message the resource has already been scheduled. Depending on the message returned, try with next resource internally and book the next resource...

I am just getting into the .net programming. I know i need to include namespace
to make use of MessageBox.

Is there any other reason for not getting this option?

Can anyone tell me how do i get the MessageBox in Asp.net..?

MessageBox.Show ("Welcome")

Which namespace should i Include..?

Thanks!
