URLDownloadToFile无法正常工作

Question

URLDownloadToFile会自动将文件下载到缓存而不是特定路径

示例：

URLDownloadToFile正在下载文件到缓存路径C:\Users\38100442\AppData\Local\Microsoft\Windows\INetCache\IE\KUQPK734而不是特定路径D:\example\filename.pdf。我希望所有文件都在D:\example\filename.pdf下载。

请参阅以下代码

Private Declare Function URLDownloadToFile Lib "urlmon" _
                         Alias "URLDownloadToFileA" ( _
                         ByVal pCaller As Long, _
                         ByVal szURL As String, _
                         ByVal szFileName As String, _
                         ByVal dwReserved As Long, _
                         ByVal lpfnCB As Long _
                         ) As Long
