Modifying application properties
1. Click the Application tab to configure or modify the settings for launching an application. This tab allows a user to define an application that is launched from the ActiveX Display control. To launch the application, a user must define a key combination or press the application icon (if it is set in this property page) in the ActiveX Display toolbar.
2. Type the path of the application in the Application Path field or click on Browse to find the application.
3. In the Key to trigger application launch panel, you must select a combination of the system keys (Shift, Ctrl, and/or Alt) and any key from the drop-down list as shown in the panel above.
4. To display an icon representing the application in the ActiveX Display session's toolbar, select the Show Launch icon on Toolbar checkbox.
Note
The parameters entered in the Data Source panel must be meaningful to the application to which these parameters are passed when it launches. The parameters entered in the Data Source panel must be meaningful to the application to which these parameters are passed when it launches.
5. When the From Selected Fields radio button is chosen, select Title from the drop-down list and enter values in the Row and Column fields that correspond to the position of the title of your host screen. Enter a value in the Length (Opt) field. (If you leave this field at zero, then all of the data in the corresponding host field will be validated). Suppose you enter 3 in the Length (Opt) field and you have selected Title from the drop-down list. The first three characters of the host screen title will be compared against the first three characters of the name in the Screen Title box.
Notes
•  If you enter the value of 0 into the Row, Column, and Length(Opt) fields, the Screen Title will not be compared and validated when you launch your application even when the wrong host screen is active. Type the name of the host screen that will be active (when the application is launched) in the Screen Title box. The name that you enter in this box will be validated when you launch your program. In other words, the Screen Title will be compared with the name and position (based on the Row and Column parameters) of the host screen title. If no screen title is defined, no host screen validation is performed.
•  If the Row and Column co-ordinates are wrong and/or the Screen Title doesn't match that of the host screen, an "Invalid Co-ordinates: Title" error message or an "Invalid Co-ordinates:Field x" error message will appear (x refers to the number of a particular field, one through five).
Select a Field from the drop-down list and fill in the same parameters as you did for the Title option. There are five Field parameters.
6. When the Entire Screen radio button is selected no validation of the host screen is performed. When the application is launched, the entire screen buffer is passed to a portion of memory that is shared by all instances of the ActiveX Display session and the application. You must define a Share Memory: Name and a Share Memory: Size that both processes will understand. The ActiveX Display session passes the screen buffer data to the application via a memory buffer that is shared by both.
Important
Be careful when you change the Share Memory: Name and Share Memory: Size. Each time they are changed, a new Share Memory object with the new size is created. If prior to changing these settings, the application has already been launched (and the process is still alive), the application won't be able to access the new Share Memory object. Also, the current instance of an ActiveX Display session won't be able to re-launch the application. Close the application before making changes to the Share Memory settings. Remember: each instance of the ActiveX control must have the same Share Memory: Name and Share Memory: Size for the same application.
7. Enter a name in the Share Memory: Name box.
8. Enter a value in the Share Memory: Size box.
Note
Several instances of the ActiveX Display control can launch the same application. However, only one instance of the ActiveX Display control can write to the shared memory buffer at a time. The other instances of the ActiveX Display control have to wait until the application reads the memory buffer data before they can to write to the shared memory buffer.
9. Click Apply or OK to accept the current modifications.
•  If you click OK, the system closes the ActiveX Display Properties dialog box and applies your change to the active session.
•  If you click Apply, the system applies your change to the active session but leaves the ActiveX Display Properties dialog box open.
•  Click Cancel to undo any changes that you made.
