- Open the sample database Northwind.mdb.
- Create a new form. Name the form Form1. Open the new form in Design view.
- Add a command button to Form1. Set both the Name property and the Caption property to "Command1."
- Add a text box to Form1. Set the Name property to "Text1."
- Right-click Command1, click Properties, and then click the Event tab.
- In the On Click event procedure, click [Event Procedure] from the drop-down list, and then click the ellipsis to start the Visual Basic Editor.
- Modify the Command1_Click procedure to the following:
Private Sub Command1_Click()
Me!Text1 = LaunchCD(Me)
- On the Insert menu, click Module.
- Copy and paste the following code sample in the new module.

OpenFile.lpstrInitialDir = "C:\"
OpenFile.lpstrTitle = "Select a file using the Common Dialog DLL"
OpenFile.flags = 0
lReturn = GetOpenFileName(OpenFile)
If lReturn = 0 Then
MsgBox "A file was not selected!", vbInformation, _
"Select a file using the Common Dialog DLL"
LaunchCD = Trim(Left(OpenFile.lpstrFile, InStr(1, OpenFile.lpstrFile, vbNullChar) - 1))
- On the Debug menu, click Compile and Save All Modulesif you are using Access 97. If you are using Access 2000 or Access 2002, click Compile Northwind, and then close the Code window.
