There are a variety of configuration file variables that enable you to customize the appearance and behavior of the Display Manager for each application you create. Once such variable is DispMgrFullScreen, which can be set under the [SYSTEM] section of your application’s Config.ini file, which is stored in your application’s directory.
By default, the DispMgrFullScreen variable is set to 1 (true), indicating that the Display Manager will encompass the entire monitor area and will not have a Windows title bar. The absence of a Windows title bar means that there will be no close button available to operators. If it is your intention to prevent users from closing a VTS application, it is recommended that you leave the DispMgrFullScreen variable set to 1.
If you wish the Display Manager to display a Window's title bar and buttons, but do not wish some or all users to be able to close the application using the Windows close button, you can deny their security account the Application Close system privilege (see Denying the Application Close System Privilege).
It should be noted that even if you set the DispMgrFullScreen variable to "1" (no Windows title bar or close button) and/or deny the Application Close privilege, users will still be able to stop the application using the VAM's Stop button. It is recommended that you additionally hide the VAM from operators, please refer to Configuring the VAM to be Hidden.
Note: By default the Display Manager has been set to run in full screen mode. Unless you or another VTS developer has changed the DispMgrFullScreen variable for your application, you will not need to modify it at this time.
Configuring the Display Manager to Run in Full-screen Mode Using the Config.ini Configuration File
To configure the Display Manager to run in full-screen mode:
1. Open the Config.ini configuration file (located directly within your VTS application's directory) using the text editor of your choice (e.g. Notepad, WordPad, or UltraEdit).
2. Locate the [SYSTEM] section heading in the Config.ini file.
3. Locate the DispMgrFullScreen variable. (If the DispMgrFullScreen variable does not appear under the [SYSTEM] heading in your Config.ini file, enter it as shown in the example below.)
4. Set the DispMgrFullScreen variable equal to 1.
[SYSTEM]
DispMgrFullScreen = 1
5. Save and close the Config.ini configuration file.
6. Restart your application for the change to take effect.
Further information on the Config.ini configuration file can be found in "VTS Programmer’s Guide: Introduction to Config.ini and in Config.ini [SYSTEM] Section Variables for the Display Manager".
Now that you have configured the Display Manager to run in full-screen mode, you might wish to configure the VAM to be hidden when VTS runs.
