PRB: Script Code Runs During AddCode Method

MORE INFORMATION

With Active Scripting, unlike Visual Basic and most other languages, statements are allowed outside procedure definitions. This is to allow the script to automatically initialize itself at load time.

This article assumes that you are familiar with the programming language being demonstrated and the tools used to create and debug procedures.

Steps to Reproduce Behavior

1. In Visual Basic, create a new project (Form1 is created by default).
2. Click Components on the Project menu, and then select the "Microsoft Script Control 1.0" check box.
3. Add the Script control (ScriptControl1), a text box (Text1), and a command button (Command1) to a form. Set the MultiLine property of the text box to TRUE. For ease of use, change the size of Text1 so that it accommodates 5 lines of 60 characters.
4. Add the following code to Form1:

         Private Sub Command1_Click()
           On Error Resume Next
           With ScriptControl1
             .Language = "VBScript"
             .AllowUI = True
             .AddCode Text1.Text
           End With
         End Sub
   						

5. Run Form1 and open the Debug window.
6. Type the following script in the text box:

         Sub Test()
           MsgBox "Hello World"
         End Sub
         Test
   						

7. Click the command button. The message box appears.
8. Remove the line "Test" from the script and run Form1 again. The Test code is not executed upon loading the code.
