I have a VB function Public Sub ShowMessage(ByVal message As String, Optional ByVal messageStyle As MsgBoxStyle = MsgBoxStyle.DefaultButton1) and I need to call it from C#. How could I submit the second parameter.  In VB, I can use MsgBoxStyle.Critical, but in C#, it would give me the error "the name MsgBoxStyle doesn't exist in context". Should I import a library? thanks.

That is part of Microsoft.VisualBasic, so check and see if it is referenced....

You'll have to include the Microsoft.VisualBasic assembly into your project.

MsgBoxStyle is a VB only enum, you would have made life simpler for yourself if you had stuck to the more general .Net MessageBoxIcon type for your parameter.

I can not find MsgBoxStyle in Microsoft.VisualBasic, the only thing available is VBCodeProvider. thanks.

Actually...that might not exist at all...You will have to use MessageBox.Show(), which is the .Net version

It is in there. Have you actually added a reference the the Microsoft.VisualBasic assembly, or have you only imported the namespace?

I can see it in the object Browser, but adding the assembly to Microsoft.VisualBasic does not allow you to get to MsgBox or the MsgBoxStyle Enums.  My guess is because this is really only a VB thing and not a .Net thing.  So using the MessageBox Class will allow for compatibility between VB and C#.

you are right, I need to add reference to microsoft.visualbasic first, then I can refer it. I will use messagebox instead
