add reference to .NET framework DLL

in CSI, is there a way add a reference to one of the .NET framework DLL. For example, if I want to use the MessageBox class from the System.Windows.Forms.dll assembly in a form script, how can I do that? When I try adding the reference, the script won't compile.

any idea?

thank you

Form side, I don't think you can. One thing I've noticed at least FormScript side (in v9) is it seems to favor VB.NET over C#.

Do you need the Windows message box specifically? Application.ShowMessage() is the FormScript function to use to pop up a window.

Yes - you need to add the DLLs to a folder that the application can "see" the DLL. I can't remember what folder that is specifically, off the top of my head. The message box class should work, as I've used both MessageBox and Application.ShowMessage()

I'll see if I can't find where I've stuck DLLs in the past to make them work with form scripts.

In the Form Script you can also use the VB MsgBox

Thank you for your quick replies.

I ended up opening an incident with Infor. Answer is you need to add a special line in the top script header. For example if you need to add a reference to the System.Windows.Form DLL, your header would look like this (I put the specific line in bold/red):

Option Explicit On
Option Strict On

Imports System
Imports Microsoft.VisualBasic
Imports Mongoose.IDO.Protocol
Imports Mongoose.Scripting
Imports System.Windows.Forms

'// <Ref>System.Windows.Forms.dll</Ref>

Namespace SyteLine.FormScripts
Public Class JobOperations
Inherits FormScript

you can also run the following query against your forms DB to find the exact syntax:

SELECT * FROM activexscriptlines WHERE codeline LIKE '%''//%'

hope this helps.

Did this format change in 9.01.10/12? I'm trying to access User32.dll in C# using:

// <Ref>PATH_TO_MY_DLL</Ref>

but the WinStudio compiler keeps telling me its in the wrong format. I know I had this working in 9.01.01 in a test program but I don't have that code anymore.
