没有保存对话框的下载文件

Question

In VB.NET I need to download a file from the web but without the save dialog box appearing. I am using a .net web browser control.

The catch here is I do not know the url of the file that has to be downloaded. It is getting passed by the website.

For example: If I pass the following url in browser " http://www.ncdex.com/MarketDataAction_bhavCopySubmit.action " then webbrowser file download event gets fired and a save file dialog box appears. After this I have to manually click on save and then save the file to a specific path.

I want to automate this process which means file gets saved automatically to the path I want.

Can this be done ? Otherwise I will then have to use sendkeys to manage the dialog box which may not be easy.

If you're not opposed to using a different class than the WebBrowser control for this particular functionality you can leverage the WebClient class to make this easy:

    Dim strURL As String = "http://www.ncdex.com/MarketDataAction_bhavCopySubmit.action"

    Dim strFileLocation As String = "C:\SomeLocation\SomeFileName.SomeExtension"

    Dim objWebClient As New System.Net.WebClient()

    System.IO.File.WriteAllBytes(strFileLocation, objWebClient.DownloadData(strURL))
