當我在執行LabVIEW Real-Time即時控制應用時,檔案對話框出現”Canceled By User”訊息

主要軟體版本: 6.1
主要軟體修正版本: N/A

問題: 當我在執行LabVIEW Real-Time即時控制應用時,若我使用File,會產生”canceled as true”的情況。若是使用Open/Create/Replace File.vi則會得到error 43 (Operation canceled by user)。兩者情況下我都未看到檔案對話框可選擇?

解答: 這是因為Open/Create/Replace File.vi使用File Dialog.vi以選擇開檔路徑。File Dialog.vi嘗試開啟系統中的檔案選擇對話框,但是LabVIEW Real-Time系統環境並無此一檔案選擇對話框。因此,可改用位於Function>>File I/O>>Advanced File subpalette中的List。
