## 顯示輸入無效值時的錯誤報告

當儲存格中輸入了無效的資料時，會顯示您在 [內容] 區域內進行輸入的錯誤訊息。若已啟用，則會顯示此訊息以防止無效的輸入。

對於這兩種情況，如果選取「暫停」，無效的輸入會被刪除且先前的數值被重新輸入儲存格中。如果您按一下[取消]按鈕關閉「警告」和「資訊」對話方塊，也會出現相同的情形。如果您按一下[確定]按鈕關閉這些對話方塊，則無效的輸入不會被刪除。

### Sample macro:

Below is a sample function that can be called when an error occurs. Note that the macro takes in two parameters that are passed on by LibreOffice when the function is called:

- CellValue: The value entered by the user, as a String.

- CellAddress: The address of the cell where the value was entered, as a String prefixed with the sheet name (e.g: "Sheet1.A1").

The function must return a Boolean value. If it returns True, the entered value is kept. If the function returns False, the entered value is erased and the previous value is restored.

        Function ExampleValidity(CellValue as String, CellAddress as String) as Boolean
            Dim msg as String
            Dim iAnswer as Integer
            Dim MB_FLAGS as Integer
            msg = "Invalid value: " & "'" & CellValue & "'"
            msg = msg & " in cell: " & "'" & CellAddress & "'"
            msg = msg & Chr(10) & "Accept anyway?"
            MB_FLAGS = MB_YESNO + MB_ICONEXCLAMATION + MB_DEFBUTTON2
            iAnswer = MsgBox (msg , MB_FLAGS, "Error message")
            ExampleValidity = (iAnswer = IDYES)
        End Function
