AP ShellExecute

version 11 (Modified)

Compatibility Note: This command is now obsolete; it is kept only for compatibility reasons and will be removed in future versions of the plug-in. It is strongly recommended to use the LAUNCH EXTERNAL PROCESS command of 4D. Note that starting with version 11.0 of 4D, AP ShellExecute only works under Windows.

AP ShellExecute (fileName{; mode{; param}}) Longint

Note: This command only functions under Windows. Under Mac OS, it has no effect.

The AP ShellExecute command enables you to launch an application or open a document from a 4D database.

In the fileName parameter, pass the name or complete (absolute) access path of the file to be launched. When the application or document to be opened is located next to the database structure, it is possible to pass only the file name or a relative access path.

Simply indicate a document name and Windows handles the execution of the associated application.

The mode parameter enables you to specify the display mode of the window in which the application will be launched:

• if you pass 0, the window will be normal;

• if you pass 1, the window will be full-screen;

• if you pass 2, the window will be reduced and will appear in the Windows task bar.

The param parameter enables you to pass any additional type of parameter that may be necessary for the launched application. For instance, if you use this command to launch a Web browser, you can pass a specific URL in this parameter.
