Message( error id, buttons, default button )
| Message | Displays an error message dialog box and returns the button the user pressed. |
| error id | An integer constant, variable, EQUATE, or expression that indicates which ErrorClass.Errors message to show in the dialog box. |
| buttons | An integer constant, variable, EQUATE, or expression that indicates which Windows standard buttons to place on the dialog box. This may indicate multiple buttons. |
| default button | An integer constant, variable, EQUATE, or expression that indicates the default button on the dialog box. |
The Message method displays a Windows-standard message box containing the error message text from the Errors property, and returns the number of the button the user presses to exit the dialog box. This method provides a simple, centrally maintainable, consistent way to display messages.
Implementation:
Uses the MESSAGE statement to display an application modal window with a question icon, the caption defined in the Errors property, and the message text defined in the Errors property.
The ABERROR.INC file contains a list of default symbolic constants for the error id parameter.
The EQUATES.CLW file contains symbolic constants for the buttons and default button parameters. The EQUATEs are:
BUTTON:OK
BUTTON:YES
BUTTON:NO
BUTTON:ABORT
BUTTON:RETRY
BUTTON:IGNORE
BUTTON:CANCEL
BUTTON:HELP
Return Data Type: LONG
Example:
!attempted auto increment of key has failed,
!show Message box with Yes and No buttons, the default is No
GlobalErrors.SetErrors !Set value of %ErrorText macro
IF GlobalErrors.Message(Msg:RetryAutoInc,BUTTON:Yes+BUTTON:No,BUTTON:No) = BUTTON:Yes
CYCLE
