The following are valid Windows 95/ Windows 98 (and for the most part, Windoes NT4 as well) control panel property page and wizard launch statements that will initiate the various control panel applets, and may also include the ability to specify the active tab on multiple-tabbed property pages. Some systems may not have all the control panel applets or related applications installed; on those systems executing the statement produce no result.

To immediately test the desired statement, use the Windows Run command from the start menu, and paste in the code line below. In a Visual Basic application, use the Shell function or similar routine to launch the control panel app. Maintaining commas, spaces and special characters is extremely important, so take care when pasting into a string in the Visual Basic environment. It may be advisable to first enter an empty string ("") and then paste into that to avoid VB reformatting the string as an expression.

If you are interested in an overview of the rundll and rundll32 interfaces as they apply to Win32 and NT4, Knowledge Base article Q164787 has been paraphrased here.

comments: Windows NT, it is possible to bring up a predefined Windows Dialog box for connecting to a network printer - the ConnectToPrinterDlg API. However, this dialog is not accessible by Visual Basic programs running under Windows 95. Therefore, you must use a Command line equivalent statement to invoke the "Add Printer Wizard" under Windows 95 as detailed above. (KB article Q154007)
