View 3 RepliesI would like for my program to navigate via textbox1.text with multiple lines and multiple url links inside of it. I know how to make the webbrowser1.navigate via textbox1.text with multiple lines, however I want my webbrowser to navigate to each url every 1-1.5 seconds once button1 is clicked. Yes, my webbrowser1 will navigate to the specified urls via the textbox1.text (multilines) with a button click, but I need the webbrowser1 to navigate in a order sequence from top to bottom of Textbox1.text (multiplelines) every 1 second. Here is the current code that I have to navigate via multilined textbox1.text control in order sequence:

Basically I have a webcrawler app which uses a web-browser control to navigate to a URL. Once the page is loaded, I use the function below to grab the HTML. Once I obtain the HTML, using HTML Agility Pack I extract the plaintext. Once this is down, with a click of a button I save the url, and plaintext to the database (using sql server).
tb_HTML.Text = WebBrowser1.document.Body.OuterHtml
Now my question is how can I carry the above as a background process, whereby say I have a form and enter all the url I need to extract the plain text from i.e. download the HTML and then using HAP extract the text and then automatically save the result inside the dB.
I can create them using Ctrl+T(webbrowser controls and all) but after that I don't have any idea on how to control them(let's say I select the 5 tab and I don't know how to make that web browser control to navigate to a given webpage). I was thinking of creating an array of webbrowsers but I don;t know how that works.
View 2 RepliesIn my app I am using a web browser control, I am displaying a list of files that are there in selected Directory, when the file type is of some image I do it as WebBrowser1.Navigate(sFileName), the image is then displayed in the Web Browser Control, when there is Word Doc I had code that converts the word doc to HTML and it is displayed in the WB Control all good so far, now when the file is of type xls, xlsx I am not converting the file to HTML instead I just use the navigate command and open the file in Excel so that user can then edit it and save it on his system. Now the problem is lets say I am toggling through pages in Directory first file is Image so it will be displayed next when it is Excel file then it will open the file in MS Excel but the WebBrowser COntrol has that previously opened image, I want to clear that when the excel file is opened. So here is what I tried. [code]It navigates to Excel file but does not display text and the image from previous file persists in the web browser control.I even tried to navigate it to "about:blank" but it then does not navigate to Excel file.
View 2 RepliesI have a webbrowser1 control that navigates via Textbox1.text (W/multiplelines) and set on a Timer1 (every .25 seconds).My issue is that I need to navigate to at least 1200-1500 urls before Timer1.stop (), but my webbrowser1 seems to only make it to 200-500 max, before I get an error saying that my program is "Not Responding" and freezes.

I am using VB 2008.I've successfully "scraped" web sites before but I am having a problem now.I use a web browser component.I retrieve the test from the control and then I search the text for the information I am looking for.BUT, when I try to do this a website that displays its information in FRAMES, it does not work.The web browser correctly displays the page, but the text only includes text saying that I need to use a browser that can handle frames.I do not understand how the web browser control can correctly display the web page (including the info that I am looking for, but the text/source/document property of the web browser does not include all of the text on the page.

View 1 RepliesI recently upgrade a project from vb 6 to 2008. Most of the code runs fine.I have a webbrowser form control that I use to navigate local files and display them with. (i have a file list box that you click which calls the navigate of the browser control). Most file types i have test work fine and display just as they would in a real browser window. Excel, PDFs, etc... so examples of files that utilize "plugins" like acrobat reader inside the browser work great. Tiff files are the exception. No error is thrown in vb, but the browser throws 2 runtime errors, included at the end here. After the browser errors are ignored the program continues execution but will just not display the file.
i can type the path to the file (eg c: estfielsfilename.tif) in a regular browser window and it displays just like it should, inside IE, using a plugin.Prior to upgrading, depending on what was installed on the computer, navigating to a tif would open the tif with picture and fax viewer, or display it with a tif viewer plugin.

I have writtine a program in VB 2008 that uses "webrowser1.navigate" in a browser that I created on a form in my application, so that I could add buttons for other functions on that Form and to load a web page with Flash content. Everything seems to work fine on 32 bit machines but, on 64 bit machines when the web page is loaded, Falsh content does not work and I get a Security Warning asking "Do you want to install this software?" and the software is Adobe Flash Player. IE is 32 bit (on 64 bit machine) and has Flash Player installed and the Flash content works for this web page using IE.Is ther some code that I should add or a property that I should change on the VB 2008 Form containing the browser that I created, so that the Flash content will work?

[code]Close to no real programming skills (PhotoShop artist turning Visual Basic Beginner)This is a snippit of the code used in my browser. Basically the items that are in the list box are loaded from a text file hidden in the installation directory so a manager (or such) will be able to edit which websites are navigate-able.Here comes the problem though, I have not been able to get it to work correctly it will not block any of the listbox items. If I can remember it will only block the site which is selected.How can I re-code it to make the program block all the items in the listbox instead of just one.(Also if not too much trouble how can I make something that will enable and disable the code)BTW this isn't a commercial program or anything just a project I have been working for ever at home.

I have been searching a lot online but couldn't find a solution for my problem. I want it to refresh every certain interval of time without this message to display. Now Ican't minimize my program because I'm putting an automatic Sendkeys.send("{Enter}") after the refresh to get rid of that message by clicking on "Retry".And If I minimize it the Enter will be executed on the active Window, which might be any other Window.
