# DoEvents Function

Transfers control to the operating system during macro execution, so that it can process the events in waiting.

DoEvents provides compatibility with VBA. It always returns 0. Using it in LibreOfficeDev is not necessary.

### Syntax:

            [Call] DoEvents[()] As Integer

### Example:

Both examples set a progressive counter on the first cell of a newly opened Calc document.

          Sub DoEventsExample
              Dim i As Long, sheet As Object, cell As Object
              sheet = ThisComponent.Sheets.getByIndex(0) ' sheet 1
              cell = sheet.getCellByPosition(0,0) ' cell A1
              For i = 1 To 20000
                  cell.setString(Str(i))
                  DoEvents
              Next i
          End Sub ' DoEventsExample

          Sub DoEvents_example
              Dim i As Long, ui As Object
              GlobalScope.BasicLibraries.LoadLibrary("ScriptForge")
          	Set ui = CreateScriptService("SFDocuments.Calc", ThisComponent)
              For i = 1 To 20000
                  ui.SetValue("A1", i)
                  DoEvents
              Next i
              ui.Dispose()
          End Sub ' DoEvents_example
