VS 2005 : Automating CSV Download Using Webbrowser Control?
Apr 11, 2009
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.

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.

I am automating a javascript web form submission process using webbrowser. I would like to use something without a UI but don't think httpresponse etc would do all that is needed. My code works but I think is not designed correctly. I think I should be breaking each step into its own sub or function. In its current state I think every time a page is refreshed/redrawn all the code is running which makes causes endless looping of clicking a link which is on its own destination page. What that means is click the link and the page refreshes with new information but does not navigate to a new page. So the code looks for the link and selects it over and over and over .... This I think needs to be subbed or done as a function instead.
Here's the code.
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Part 1: Load elogging login page in Form_Load event
WebBrowser1.Navigate("[URL]")

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?

I have several web browser controls on my form. I don't want to have in the content any styling like font etc because this is controlled by my css in my dynamic website. However I would like to format my browser using the same css as my website so they look very similar. Is there a way to assign a css file the the web browser control in vb.net?

I am navigating to a web page with my webbrowser control
[Code]...
and this works on most pages. Now I'm going to a page that I guess there are errors in the page and I get a box asking me if I want to debut in IE's built in script debugger or something to that effect. Is there any way to have the system ignore this message and continue to load the page as normal

I want to load some HTML into a webBrowser control, then operate a particular bit of code when it has finished loading.The code operates fine as long as I pause to wait for it to finish loading. If I just run the code without pausing, it sometimes messes up the display. webBrowser.Document Completed doesn't run after Document.write.I don't want to use webBrowser.DocumentText = "..." because that makes an annoying click sound every time it refreshes. A lot of people are annoyed by this. There are countless threads asking how to turn off the click, and using .write seems to be the only solution that doesn't require hacking the registry.

I have two web browser controls on my form. I also have several buttons like bold, underline, etc. My probem is the gotfocus of the web control is not working correctly. If I click on the web browser control to add text the gotfocus is not fired. If I click on a text box first and then click in the browser control it is fired. I need to know which has focused so the bold etc know which control to work on.

I'm trying to access a secured website using vb 2005 and webbrowser control. I've got the credentials, the script can pass the login page but when trying to navigate to the second page within, the page is being redirected back(to the first page after logging in). The second page I'm trying to get to retrieves the data from a database and displays some options for the user to select in order to prepare a report which can be downloaded after the fields selections. And I wanted my script to do this automatically without user interaction.

Is it possible to load HTML content into the HTMLDocument object without having to use the WebBrowser control? I have an html file stored locally that I want to parse in order to find out which checkboxes are on and which are off.
All of the examples I've found use the Webrowser. It just seems convoluted to have to use the WebBrowser in order to get to a DOM object.

I'm attempting to populate fields in a processing webpage [URL] and having a small problem.
I can add the email and antenna heights easily but how do I manipulate a file browser (file upload) and option input boxes (Antenna Type) from within my vb app?
It might be the long way around but i'm doing it via searching each of the html elements to find the named fields I'm looking for:
Dim intWork As Integer
For intWork = 0 To WebBrowser1.Document.All.Count - 1
strWork = WebBrowser1.Document.All.Item(intWork).Name

I'm new to visual basic & have learned many new things in such a short period of time from being on the MSDN forums. I have learned particularly in the subject of automating web browsing control using the getattributes etc., but I have tried everything that I have seen in the forums to auto click the "Settings" link in a created gmail account and then have the browser automate the "Forwarding" to another gmail address. I haven't found a solution anywhere to accomplish this.
So here is an account to try out in which this should only take a few mins to a veteran coder:

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?

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 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.
