When a user clicks on the button called "save" on a webpage opened in webbrowser1, it downloads a text document to the hard drive and explorer asks user is asked where it should be saved. How can I intercept this and directly download the textfile into a richtextbox without triggering the "save file to disk" alert ?Maybe an IDownloadManager implementation?

View 1 RepliesI just have a few problems regarding my application, any suggestions would be great, thanks. (I'm quite new to this stuff, making an application(s) for fun haha.)
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
End If

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.
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.
View 3 RepliesHowever, 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.

I 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?

getting the webbrowser to stop downloading them?
I 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.
I would download sourcecode like "WebClient.DownloadString("SITE")"But without Webclient is that possible?

View 1 RepliesI am having a hard time with my project. A description of it is here (Question #2) I don't know where to begin with classes. I have a functioning program, but it isn't working as designed. Changes and updates are being written directly to the text files, so the listbox doesn't display current information unless it is refreshed in some way. The instructions say that this program should commit files once a "Save accounts to File" button is clicked. Obviously, my program doesn't make use of the button. I was going through another project where changes were written to a list box, and committed to the files upon exit. However the text files were in LSV format, and the program used an array of structures instead of classes.
