IMPORTANT: Microsoft provides programming examples for illustration only, without warranty either expressed or implied, including, but not limited to, the implied warranties of merchantability and/or fitness for a particular purpose. This article assumes that you are familiar with the programming language being demonstrated and the tools used to create and debug procedures. Step-by-Step Example -------------------- 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 Form1. 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 with 60 character each. 4. Add the following code to Form1: Private Sub Command1_Click() On Error Resume Next With ScriptControl1 .Language = "VBScript" .AllowUI = True .AddCode Text1.Text .Run "Test" End With If Err Then MsgBox Err & " " & Error ListErrors ScriptControl1 End If End Sub Private Sub ListErrors(S As ScriptControl) With S.Error Debug.Print "Number:", .Number Debug.Print "Source:", .Source Debug.Print "Desc:", .Description Debug.Print "Line: " & .Line, "Column: " & .Column Debug.Print "Text:", .Text Debug.Print "Help File:", .HelpFile Debug.Print "Help Context:", .HelpContext Debug.Print 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" Err.Raise 555, "Test", "Custom Error", "test.hlp", 5 End Sub 7. Click the command button. As a result, the following error appears in the Debug window (the actual output may vary depending on the version of the script control you are using): Number: 1002 Source: Microsoft VBScript compilation error Desc: Syntax error Line: 2 Column: 16 Text: MsgBox == "Hello World" Help File: Help Context: 0 8. Remove the == from the MsgBox line and click the command button again. 9. The MsgBox appears and then error "555 Custom Error". The Debug Window displays the following: Number: 555 Source: Test Desc: Custom Error Line: 3 Column: 8 Text: Help File: test.hlp Help Context: 5 NOTE: The column number may vary depending on whether you cut-and-paste the code or type it in manually without all the leading spaces.
