    automate File Download Dialog Box in Internet Explorer?

    I have searched this forum and others for my current dilemma, but to no avail. There have been several related posts but I haven't seen any solutions!

    1. I am downloading zip files from a password protected website using Internet Explorer Automation. I am able to navigate to the site, login, and get to the stage where the file download dialog box pops up, but I am uncertain how to click "Open" (or "Save" and then choose a name and location). I am unable to use URLDownloadToFile due to the way the website is set up.

    2. As a quick workaround, SendKeys doesnt works. . This is a bit of a hassle because I'd like to loop and download many files .

    Any thoughts? Should I just assume that a programmatic solution doesn't exist? Im using now the visual studio 2008.
    Cheers for your help!

    just use the WebClient class to download the file itself.

    Re: automate File Download Dialog Box in Internet Explorer?

    thank you sir,

    i ve tried like this
    Code:
    static void Main(string[] args)
            {WebClient wc = new WebClient();
                WebProxy wp = new WebProxy();
                wp.UseDefaultCredentials = true;
                wc.Proxy = wp;
                wc.Credentials = new NetworkCredential("xxxxx", "yyyyyy");
    
                
                string hostUri="http://www.codeguru.com/";
                string uriSuffix = "http://www.codeguru.com/csharp/.net/net_asp/article.php/c17151/Images-on-the-Fly-in-ASPNET.htm";
                // Create a new WebClient instance.
    			WebClient myWebClient = new WebClient();
    
    			// Set the BaseAddress of the Web Resource in the WebClient.
    			myWebClient.BaseAddress = hostUri;
    			Console.WriteLine("Downloading from " + hostUri + "/" + uriSuffix);
    			Console.WriteLine("\nPress Enter key to continue");
    			Console.ReadLine();	
    	
    			// Download the target Web Resource into a byte array.
    			byte[] myDatabuffer = myWebClient.DownloadData (uriSuffix);
    
    			// Display the downloaded data.
    			string download = Encoding.ASCII.GetString(myDatabuffer);
    			Console.WriteLine(download);
    
                Console.WriteLine("Download of " + myWebClient.BaseAddress.ToString() + uriSuffix + " was successful.");
    
            }
    but it throws a "WebException
    (407)Proxy authentication required."

    dnt know what to do.

    i ve used web browser control before to login to the site, but when i use web client control i cant even login. can i use webbrowser and webclient control together?

    login using web browser and to click the button there

    to download using webclient

    I found a way to do this with Internet Explorer 6 in Windows XP SP3.

    (Sorry, VBA code)

    'ButtonHwnd is the pointer to the Save button
    Private Declare Function SetCursorPos Lib "user32" (ByVal X As Integer, ByVal Y As Integer) As Long
    Private Declare Sub mouse_event Lib "user32.dll" (ByVal dwFlags As Long, ByVal dx As Long, ByVal dy As Long, ByVal cButtons As Long, ByVal dwExtraInfo As Long)
    Private Const MOUSEEVENTF_LEFTDOWN As Long = &H2
    Private Const MOUSEEVENTF_LEFTUP As Long = &H4
    Dim pos As RECT
    ' We get the button position
    GetWindowRect ButtonHwnd, pos

    ' We simulate an entering of the cursor in the button. IE think this is a human :-).
    ' We need three steps: out, entering and in.
    ' Out
    SetCursorPos (pos.Left - 10), (pos.Top - 10)
    Sleep 100
    ' Entering
    SetCursorPos pos.Left, pos.Top
    Sleep 100
    ' In
    SetCursorPos (pos.Left + pos.Right) / 2, (pos.Top + pos.Bottom) / 2

    ' We do clic with the left button. You can use SendInput instead
    ' With 400 miliseconds it works.
    mouse_event MOUSEEVENTF_LEFTDOWN, (pos.Left + pos.Right) / 2, (pos.Top + pos.Bottom) / 2, 0, 0
    Sleep 400
    mouse_event MOUSEEVENTF_LEFTUP, (pos.Left + pos.Right) / 2, (pos.Top + pos.Bottom) / 2, 0, 0

    Please, tell if it works for you.
