I have just recently started using vb.net from vb6. I have written a program that retrieves certain posts from a forum. To clarify, it does this:
1) Login to forum and get SID
2) Navigate to a page (with SID) and retrieve required code.
Thats it.To retrieve the page source, im using this:

View 5 RepliesI use the webbrowser control to navigate to certain websites and login and retrieve some data. For that I created a sub for each website. On the form i have a button that calls every sub when clicked. The problem is that I don't know how to pause or stop the process once started. If I quit the program it will still run in the background until all calls complete. I tried to use a thread, but that doesn't go well with the webbrowser control.

I'm using a webbrowser control in my program and I navigate to a page that uses sessions. I need to delete them somehow and I tried to close IE and enter it again and it worked, the sessions were deleted. But I've done it manually, and I need to do it through my program, so is there a way to imitate the closing and reopening of my webbrowser control?

View 10 RepliesI'm using a WebBrowser control in my current program in a bit of a bastardized way: I don't use it visually, I just use it because I'm more familiar with its events.
So, basically, I create a WebBrowser control and navigate to a page to login. Then, when logged in, I create a new WebBrowser control and navigate to a different page.
I've used this program for four months with no difficulty. Starting today, though, the second phase of that has been going really, really slowly. What used to take 3-5 seconds is taking 25-30 seconds. It still works eventually, it just takes a while.
Usually I would assume this was a server problem. However, navigating to the exact same URL in Firefox happens extremely quickly. Weirder still, within the program there is a user WebBrowser control -- I can copy/paste the URL the previous (not visible) WebBrowser was navigating toward into this user WebBrowser, and it goes just fine.
What in the world could be holding up this other "custom" WebBrowser? I don't even know where to begin in diagnosing this.It might be important to note that the site this is working based off recently underwent some changes -- but I can't imagine why that would affect only these "custom" WebBrowsers and not the user one in the same program.
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?

View 3 RepliesI have a VB.Net project that creates a new Webbrowser instance which then navigates to a page in order to read the HTML into a variable ( then modify this before displaying in a visable webbrowser).The issue i have is that the webbrowser navigate just reads the page from the cache and does not read it from the server.
View 2 RepliesI need to address a file in my code. this file isn't located in my main project, but in a library project.

I am creating a notes software. This is just a simple application that will show the data from the database which are Notes_Title, Due_Date, Priority. I display the data with datagridview. I also added a checkbox for each row to the datagridview to mark as check if the Notes_title is already done. In displaying the data, I need to display only a 5 data in a row.So, I create a another CLASS that will only show 5 rows per page. But the PROBLEM is, if I mark the checkbox as check in the first page then if I turn it to the next page the checkbox in the first page that mark as check will be uncheck if I turn it back to the first page. The mark check in the checkbox will mark as uncheck if I turn the page. How can I make it mark as check even if I turn the pages? And How can I save the data row as done if I check

View 1 RepliesI'm using the following code to retrieve a URL and then parse the HTML from the page:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.Click
Dim Temp As String, searchstr As String
[Code]....
I think my problem is that I don't exactly understand how I am supposed to start and end the parsing. I know that in my above code, the "meta" tag is the start and the chr(34), double quotes, is the ending.
When I modify my code, I have price line, which in th html ends with another character, the ">" sign. In the first code, the "content" tag doesn't end with another character, it just continues the line, which is easy and it works.
