Step-by-Step Example

  1. Start a new Project in Visual Basic. Form1 is created by default.
  2. Place a CommandButton on Form1.
  3. In the General Declarations section of Form1, enter this code:
          Option Explicit
    
          Private Sub Command1_Click()
           Dim oExcelApp As Object
    
           ' Create a reference to the currently running excel application
           Set oExcelApp = GetObject(, "Excel.application")
           ' Make the Excel Application Visible.
           oExcelApp.Visible = True
           ' Run the excel procedure
           oExcelApp.run "proc", "David", 30
          End Sub
    					
  4. Start Microsoft Excel. Book1 is created by default.
  5. Add a new module to the workbook.

    For Excel 5.0 and 7.0: From the Insert menu, choose Macro, and select the Module Option. This will give you a new module sheet, Module1.

    For Excel 97 and later: Press ALT+F11 to start the Visual Basic Editor. Click Module on the Insert menu.
  6. In Module1, type the following code:
    Sub Proc(sParam1 As String, iParam2 As Integer)
            MsgBox sParam1 & " is " & iParam2 & " Years Old"
          End Sub
    					
  7. Leave the workbook open in Microsoft Excel and switch to your project in Visual Basic.
  8. From Visual Basic, press F5 to run the project. Click the command button, and you should see a dialog box appear with the text "David is 30 years old" in it.
