Downloading File With WebBrowser And JavaScript Without Dialog Boxes?
May 21, 2012
I know this topic is all over the web, but I seem to have a combination of issues that is either not addressed or I can't figure out that they are addressed. Here is what I am doing. I am using Webbrowser to log into a a website and navigate to a specific page, enter some query criteria and click a "search" button. This button produces a table of files that fit the criteria. I then go through the table,navigating to the file names and compare against my database to see if I want to download. This all works well.
The issue: there is no URL behind these file names. It is a JavaScript. I am able to call the file with invokemember("click") but I get the pesky dialog box or Open or Save. Then I get the directory dialog box.
I have tried sendkeys, trie to capture the Webbrowser_downloadFile event, tried ObjectForScripting(not sure I did that correctly), all to no avail. I have tried to use WebClient, but since I do not have and actual URL for the file, I did not expect it to work. I can navigate to the href attribute, but not sure how to use it.

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 have over 12,000 documents that are encrypted in one system. I need to download them all. I had a method developed before that used a macro recorded to initiate a series of button presses but that wasn't a fail-proof way of retrieving everything I need. Currently, I'm using a webBrowser control in my windows app to accept an ID in a query string which initiates a download of the document. The save dialog box opens and then through a macro recorded process, or human process, the document is saved to a folder where I process it, stream it into a different database and then delete the file. The process then repeats itself with a different ID

I am writing a program for FEMAP API interface in VB 2008 Express. Some API commands open user dialog boxes which requires yes or OKcancel inputs. So much for automation "Sendkeys" do not work, because code execution stalls at the line which opens the dialog boxes. I need stg that runs in parallel, watches for these dialog boxes, and sends the right keystroke at the right time.

I'm programming a mass emailer for my newsletter using Outlook.Everything is working great except for two security dialog boxes...The first is how long I should give my application and the second is "if I should let my program send out the email".I do really understand this is perfect security but I need to have Outlook trust my application.These newsletters are going to 1000 people and this would be really tedious if I had to click each dialog box.

I have a very annoying problem and I'm trying to find the simplest solution possible, but I seem to keep complicating it.
My program displays a custom dialog box using the ShowDialog function (I create this form using a New constructor), but while my program waits for input in the dialogbox, my program continues to run other code, (I'm assuming initiated from other messages, but I still can't find good information on this, so as an aside to this topic does anyone have a reference about this), and arrives at this same point where the dialog box is to be displayed and displays it. So I end up getting a flood of dialog boxes.
My goal is prevent this excessive amount of dialog boxes. If the program arrives at this dialog initiation point I would like it to wait/pause until the first dialog box is finished.

I'm using a DLL in my program that is free to use in non commercial environments and it generates a dialog box every time I debug my program to remind you that it's not free for commercial use etc.. At first I couldn't care less about the popup dialog box but when your programming all day it gets really annoying. is there a way to suppress those popup dialog boxes or do I just need to go to my happy place and ignore them when they pop up?

I'm rather new to programming in general, but I have written a rather useful program for the company I work for. What I am trying to do is control the way a dialog box is displayed. I want a dialog box to pop up at certain times like 7:00 PM, 8:00 PM, etc.

I have an assignment due this week in which I have to make a app that has 5 buttons and a picture box. When each button is clicked it has to show the corresponding picture in the picture box, the fifth button closes the app.
I have the whole form set up the way it should be, but I have no idea how to write the code to make the buttons display the images and close the app.I have the images in a folder within the project folders.
I have yet to be able to find one, the one I found should how to do it using a file opener dialog and a folder browser dialog but that is not what I think my prof wants us to do, as that is more for a picture viewer app that lets the user choose the file of the image they want ot view.
All i want is for the buttons to be linked to specific photos that are part of the application itself and have them open.

I'm looking for a way to run Javascript in an instance of WebBrowser. Ideally I'd like to include a file using [Code] Problem is, the only way I'm seeing to run JS in the browser so far is by navigating the browser to a javascript) url, and I'd like to avoid that. There must be a way to interact with the DOM and add the code that I want to run in there. Right?

I'm trying to figure out how to edit a javascript variable through the webbrowser. For example, the webbrowser loads a page with a javascript variable in it:
var stop1 = 0; 'That's in the HTML code of the website.
What I want to do is have someway to modify that variable. Just like
stop1 = 1;
How to do this in Visual Basic. Is it possible?

I am developing an Outlook 2007 VSTO application that works with a commercial website.Almost all of the app's interactions with the website are done using HttpRequest objects.One user scenario does require the app to open a browser to a specific page on the site, and that page requires a Post string to provide the results of a form submit.I am using the version of the WebBrowser control that ships with VS 2008, and specifically VB.Net.My code successfully goes to the first page, after which it navigates to the actual target page (once the first page is loaded).That works, too, but if I click on the desired link on the target page, a JavaScript error pops up, stating "'j.parentNode' is not an object", with a Code of 0.I do not have access t the commerical site's internals. The page and links in question, when accessed via IE or Firefox, work correctly without the JavaScript error. The page containing the link is using Flex.Is this a problem with the nWebBrowser control?
