CompatibilityMode() funkcija

CompatibilityMode() function controls or queries runtime mode. It affects all code executed after setting or resetting the runtime mode.

Naudokite šią funkciją atsargiai, apsiribokite, pavyzdžiui, dokumentų konvertavimu.

      CompatibilityMode(Optional Enable As Boolean) As Boolean
    

CompatibilityMode function always returns the mode that is active after its execution. That is, if called with an argument, it returns the new mode; if called without an argument, it returns the active mode without modifying it.

Enable: Sets or unsets new compatibility mode when the argument is present.

CompatibilityMode function relates to Option VBASupport 1, in which case it always returns True. It is unrelated to Option Compatible compiler directive.

Ši funkcija gali paveikti arba padėti šiose situacijose:

• Scoping of variables.

• VBA būsena vykdoma naudojant komandą RmDir. VBA pašalina tik tuščius katalogus, naudodama RmDir, tuo tarpu kai „LibreOffice Basic“ katalogą pašalina rekursyviai.

• „Basic“ komandos Dir elgesio pokytis. Katalogo vėliava (16) komandai Dir reiškia, kad tik „LibreOffice Basic“ katalogai grąžinami, tuo tarpu kai VBA grąžinami normalūs failai ir katalogai.

• Color components calculation with the Red and Blue functions which are interchanged (The Green function is not affected).

Pateikiama NOT tuščias katalogas iš file:///home/me/Test

      Sub RemoveDir
      
    MsgBox CompatibilityMode() ' False
      

          CompatibilityMode( True )
          RmDir( "file:///home/me/Test" )
          CompatibilityMode False 
      
      
    MsgBox CompatibilityMode ' False
      End Sub
   

With CompatibilityMode( True ) the program raises an error, otherwise the Test directory and all its content is deleted.

Modifikuojant Dir elgesį

    Sub VBADirCommand
        CompatibilityMode( Enable := True )   ' Shows also normal files
        Entry$ = Dir( "file:///home/me/Tmp/*.*", 16 )
        Total$ = ""
        While Entry$ <> ""
            Total$ = Total$ + Entry$ + Chr$(13)
            Entry$ = Dir
        Wend
        MsgBox Total$
        CompatibilityMode Enable := False ' Shows only directories
    End Sub
