Thêm mã này vào mã của bạn. Sau đó, tất cả những gì bạn phải làm là lấy Left(strPfad, 2)
, cái này sẽ trả về một cái gì đó giống như Z:
, và chuyển nó vào DriveLetterToUNC
hàm, và nó sẽ trả về một đường dẫn UNC như thế nào \\server\mount
.
Các khai báo và hằng số phải ở đầu tệp, vì vậy hãy thêm văn bản này vào mã của bạn. Bạn cần có đủ khả năng gọi DriveLetterToUNC()
hàm để lấy thông tin bạn cần và chèn nó vào chuỗi của bạn.
