View 5 RepliesI'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.
Every time I click on download file link, instead of the internet explorer download file dialog to come up, show my second form and in it's textbox place the download link. I have been searching for this for a long time.
View 5 RepliesIn 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.
View 2 RepliesWhen 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 am currently trying to get a WebBrowser object not to download flash and images. This is just to make a lightweight browser. I know this can be done within the IE settings, but i would prefer it on an application level.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
WebBrowser1.Navigate(New Uri("http:google.co.uk"))
End Sub

I 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 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 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?

I want to download thousands of files from the web and save them locally. What is the most efficient way? It is important the failures timeout within 10 seconds.
Is there a better way to stream one stream into another? Maybe a smaller buffer, like 1024 bytes at a time, is more efficient for large files?

I am writing a few web based apps which will require a webbrowser extension. I have already used the IE webbrowser control that uses the trident web rendering engine. I believe this is MSHTML.DLL? Anyway, some of the users of my programs have complained of a few things. Particularily,
1. It seems to be a slow browser, at least compared to other rendering engines out there (webkit and gecko are 2 known ones).
2. On the developer side, it seems to be low in features. The features are sufficient in most cases, but there are some "special" things that I need.
3. It has VERY low HTML (and especially HTML5) compliance.
My question is, how much work would it take to use a different engine (such as webkit .net, which I HAVE heard of) and be able to distribute it easily. Or, if you guys feel ambitious, we could try writing a brand new engine ourselves. I know how big of a job it is, and frankly, I have no clue where to begin. I would just like your thoughts and opinions on the matter.
I am utilizing a webbrowser control in vb.net 2005 to display excel workbooks
We are using this control to open excel documents. Webbrowser.ShowSaveAsDialog() allows the user to save the excel workbook open at any location he wants
However, I don't want the user to decide where to save. Is there any way to save an excel document from the webbrowser control without going through the ShowSaveAsDialog?
On closing of webbrowser, a simple prompt to user whether he/she would like to save changes should be fine enough
As of now, I can close webbrowser control and it does not prompt the user to save the changes. Actually, all changes are lost until and unless I perform a save (Ctrl+S) manually
i have created an app to load an access database into a datagridview, which contains web urls. When button is clicked it webbrowser1 navigates to each url and each webpages document.inertext is put into textbox. This all work fine but after a while the webbrowser navigation becomes increasingly slower.
