WR ON COMMAND

version 6.5

WR ON COMMAND (area; 4DRepMethod)

The WR ON COMMAND command executes the method passed as 4DRepMethod when a 4D Write command is invoked by the user,either by the selection of a menu command or by a click on a button. If area equals zero, 4DRepMethod will apply to each 4D Write area until the database is closed or until the following call to WR ON COMMAND is made: WR ON COMMAND(0;"").

4DRepMethod receives two parameters:

• $1 is a Longint that represents area.

• $2 is a Longint that designates the command number.

Note: The list of constants and their values is available in the "WR Tabs" constants theme. You can either pass a constant name or its value.

When planning to use a compiled database, it is necessary to declare both $1 and $2 as Longints, even if you do not use them.

If you want the initial command to be executed, you need to include the following in the called method: WR EXECUTE COMMAND($1;$2).

You want to save your documents in the "Archive" folder located on your hard disk:

   C_LONGINT($1;$2)
   Case of 
   : ($2=wr cmd save as )  `When Save As... is selected
      $DocName:=Request("Give a name to your document: ")
      If ((OK=1) & ($DocName#""))
            `Save the document in the selected folder
         WR SAVE DOCUMENT ($1;"HDisk:Archives:"+$DocNom)  `Mac
         WR SAVE DOCUMENT ($1;"D:\Archives\"+$DocNom)   `Win
      Else
         BEEP  `Something is not correct
      End if 
   Else    `For any other menu command
      WR EXECUTE COMMAND ($1;$2)
         `Execute the regular action 
   End case 

      ` Form Method:
   If (Form event=On Load )
      WR ON COMMAND (Area;"TheMethod")
   End if 

WR EXECUTE COMMAND, WR Get on command method.
