Я использую <input box with type="FILE"> для загрузки файла.
Я хочу получить полный путь к загруженному файлу (путь к источнику при условии, что путь будет изменяться). Я попытался следующий код во время обратной передачи, но я не могу получить полный путь к файлу. Пожалуйста помоги.
<label class="col-sm-3 control-label">File Name : </label>
<div class="col-sm-7" style="padding-top: 7px">
<input type="FILE" name="txtFile" size="60" accept="text/plain">

set o = new clsUpload
if o.Exists("cmdSubmit") then
'get client file name
sFile = o.FileNameOf("txtFile")
'====sFile will return Data20180513.txt
response.write Server.MapPath(".")
'==== This will only return D:\BRO\IQOR.
'==== The actual path should be D:\BRO\IQOR\database\attendanceData
response.end

Я использую следующий класс для сохранения моего файла в определенном месте. Но как получить полный путь к файлу, когда я использую <input box with type="FILE"> для загрузки файла?
