Preview User Interface

The VBScript file WiDialog.vbs is provided in the Windows SDK Components for Windows Installer Developers. This sample shows how script is used to preview dialogs in a Windows Installer database.

This sample demonstrates:

• OpenDatabase method (Installer Object), the CreateRecord method, and the LastErrorRecord method of the Installer Object
• OpenView method and the EnableUIpreview method of the Database Object
• Execute method and the Fetch method of the View Object
• StringData property propertyof the Record Object

This sample requires the CScript.exe or WScript.exe version of Windows Script Host. To use CScript.exe for this sample, type a command at the command prompt using the following syntax. Help is displayed if the first argument is /? or if too few arguments are specified. To redirect the output to a file, end the command line with VBS > [path to file]. The sample returns a value of 0 for success, 1 if help is invoked, and 2 if the script fails.

cscript WiDialog.vbs [path to database][Dialog names]

Specify the path to a Windows Installer database. Specify the name of a dialog. This name must be listed in the Dialog column of the Dialog table. To view a billboard, append the dialog's name with the control's name from the Control table and append this to the name of the billboard in the Billboard table. If no dialogs are specified, all dialogs in Dialog table are displayed sequentially.
