Making An Application That Uses Multiple WebBrowser Controls And Multiple Proxies?
Dec 17, 2009
I am making an application that uses multiple WebBrowser controls, and multiple proxies.The code for changing the proxy settings are as such:
#Region "Proxy"
Public Structure Struct_INTERNET_PROXY_INFO
Public dwAccessType As Integer
Public proxy As IntPtr
[code]....
Note: getRandomProxy gets a random proxy from a list.Problem is that whenever RefreshIESettings(getRandomProxy()) is applied, the proxy will be applied to all of the WebBrowsers, while i would need to have a unique proxy for each WebBrowser. Not having this would just error out the page in the other browsers and so on.

I have an application that has 4 WebBrowser control to monitor a commercial website. I would like each WebBrowser to be using its own proxy however it looks like the proxy setting affects all the browsers and cannot be set on an individual basis.
Is there a way to have individual proxies for each WebBrowser control?

I need a multiple choice quiz but I've ran into some problems. So far i have 5 arrays: one for the questions and four for the answers. The question is displayed in a label and the answers on radio buttons. Problem one: I am using a random number generator to pull them but this allows them to be reused. How do I stop repeats. Problem two, my grading isn't always working.

attached is my project on making multiple words from 1 word
This solves the word and has an option to save. Or it solves and saves all words in a list. I tried to do it with jokers using the jokers as every letter but it slows the program down drastically.

I've been working on this project for two weeks now and I'm drained from all the hiccups I've come across. Now I've hit a brick wall.I'm making a "simple" order form in Visual Basic 2010 that calculates the amount due for an order and then from the total determines what the shipping will be. I've been able to accomplish the following tasks:accept customer data (name, address, city, state abbreviation, zipcode)calculate total with shipping costs (accurately, for the most part)clear the order form and exitBut the way I have it right now, a customer can only put in 1 order form.
Problem: I have to figure out a way to allow a customer to place an order form for multiple items. (I'll assume that a customer will not place an order for more than 20 items). So what would be the best way to go about saving the information for multiple items then calculating the cost at the end?If it's multiple form creation, how is that done? Is the keyword "Container" the way to go, and how
Snippet Code:
Private Sub total_mouseleave(ByVal sender As Object, ByVal e As EventArgs) Handles total.MouseLeave

I have a DataGridView object to which I've bound a list of objects (of type Asset) returned from a database query.I'm programming in VB using Visual Studio 2005.I want to grab two copies of the bound object (calling them oldAsset and newAsset) from the selected row in the DataGridView, update newAsset based on input from other controls on the form, and pass both oldAsset and newAsset to a function that will update the appropriate record in the DB.I try to grab the two copies like this:
Dim currentRow As DataGridViewRow = Me.AssetDataGridView.CurrentRow
Dim newAsset As Asset
newAsset = currentRow.DataBoundItem
[code]....
Opening a watch window on oldAsset and newAsset indicates that the appropriate values are pulled at this point. But when I try to change a property of just newAsset, like
newAsset.CurrentLocationID = cboLocations.SelectedValue
I see that the corresponding value in oldAsset is also changed. This is not what I want, but it's obviously what I'm telling the computer to do.

My application has a TabControl which has 5 tab pages. Each page represents a "department" and each department has to run this software. So when the user opens the application, they navigate to their department's page.
The software runs a serious of automated and manual tests. The tests are customized for each department. But I need to update the UI during each section of the test.
On the main tab, there is one panel that has 17 PictureBoxes. Each PictureBox represents one test. The PictureBox can either represent a test in progress, a test passed, or a test failed.
All of the tests are in their own code files, for the most part. And in the main form is when I call the tests and update the UI from a single method.
The issue I'm having is how to update the PictureBoxes without creating a bunch of redundant code.
When the test runs, I update the first PictureBox with "in progress", then when it completes, it's update again with pass or fail. So for a single test, I could need to place the UI update in several places, within the same code block, for planning out all the possible conditions.[code]...

I need to make 3 webbrowser (using the default webbrowser control) in my application, but I need them to use separate cookies. I want them to run independently. (ex : I put 3 webbrowser in my application, if I log in a site with a webbrowser, I'll be logged in the 3 webbrowser. I want that only one webbrowser will be logged in, not 3.)
I already found some site about it [URL]
