I'm attempting to download a file from a website using the WebBrowser control but having some difficultly determining the file path in order to download. Here's the process I'm using:
1. I login into the site using the webcontrol since it's https, e.g.
However, urldownloadfile will use proxy that internet explorer use. That part is what I want. The thing is the proxy used authentication. The proxy in internet explorer is authenticated. Using urldownloadfile will faile with error. It works without proxy.Anotehr is to copy the image to clipboard. That method is not reliable when user switch to another.
View 2 RepliesI am using a WebBrowser-Control to fill in a webform and then click at a button, this currently results in a standard Download File Dialog (you get these if you download a file using internet explorer), but instead, I have to catch this file and save it automatically with a by me defined name to a specific folder.I am trying to code a little application in vb.net which download the Export-file from my wordpress-blog, and I want to do this completely without user-interaction.Currently everything works, except the downloading of the file.I tried to catch it with the event System.Windows.Controls.WebBrowser.Navigating(ByVal Object, ByVal System.Windows.Navigation.NavigatingCancelEventArgs) but I don't see where to download the file from?
View 3 RepliesI am trying to automate the download of a .CSV file from a password protected website. This file is updated every 15 minutes, but I could get by downloading it 2-3 times a day. I would love to find a way to download this file without any user interaction.
The problem is that there is no direct URL to access the CSV file. There is a webpage with a submit button that initiates the file download. The usual File..Save As Dialog box appears, you click save and then specify the location through the second dialog box.
Looking at the source of the main webpage, I found the form containing the download button, hoping that I could simulate the POST using the HTTPRequest/Response objects, but I couldn't get them to work. The form contains three hidden variables, one of which is called "Key" with a 20 character hexadecimal string. Im assuming this key is regenerated regularly, so this may explain the constant errors I received saying "...press the back button and resubmit the previous page".
Then I decided to try the WebBrowser control. I was able to figure out how to pass the authentication through the URL and the download page appears in the browser control window. Clicking on the download button brings up the same Save As dialog as the main browser window.how to automate this process. I just need to get this csv file (which, by the way is approx 25MB) downloaded so that my scripts can use it to update our site database.
In my form I have added a webbrowser that will navigate into a URL and that URL ends with an extension (.zip) now my problem is that I want to disable the File Download Dialog in order to download it without interruption .N.B : I don't want to use the HTTP CLIENT because I need the webbrowser to navigate to another page after downloading the file.

I am writing a program that will stop the download prompt in the IE control. I have an program that has a browser. I want to fix the browser that way it would stop the download prompt from showing, and stop automatic/manual downloads. I already tried a list of file extensions, then check the URL of the browser for the file extension.

1) I'm planning to distribute this application, but the problem is if I send it to another computer the user will most likely not be "Home2" and this code wouldn't work right?.
Code:
If (File.Exists("C:Documents and SettingsHome2Start MenuProgramsStartupexample.exe")) = True Then
File.SetAttributes("C:Documents and SettingsHome2Start MenuProgramsStartupexample.exe", attribute)
ElseIf (File.Exists("C:Documents and SettingsHome2Start MenuProgramsStartupexample.exe")) = False Then
