Using Proxy with web browser control

is it possible to use two web browser controls with different proxies without writing the registry. or there might be any solution ? You cannot do this with the Web Browser Control. InternetSetOption allows you to set a proxy, but your choices are only "For all processes" or "For this process". You cannot set the proxy individually for a single control. If there's something distinct about the traffic (e.g. one control goes to 1 server, the other goes to another) you could configure the process to use a Proxy Configuration Script (search for FindProxyForURL) to chain traffic bound for different

I want to make a program in Visual Studio 2008 in Visual Basic. It involves a web browser and I want to make it auto refresh and allow people to choose the time period in which they want to auto refresh. It won't take user input but I have checkboxes that are preset. I think this may be possible using a timer and the WebBrowser1.Refresh() method. If I am mistaken, please correct me and tell me how to do this. From what I gather, it seems that you are trying to create a WinForms application in VB.NET. To accomplish your goal, you can: Create a NumericUpDown or Textbox control to allow users to

In a rather controversial decision, Microsoft has changed the traditional layout of IE User Agent (UA) string in IE11. This is what the UI string looks like in IE11: navigator.userAgent: Mozilla/5.0

Use threadpool to limit max number of threads - Attempted to read or write protected memory error

I am using some scrapping code by Noseratio found here https://stackoverflow.com/a/22262976/3499115 . He wrote it to scrape a list of urls, but I am using it, however to render only one url at a time inside another web crawler MVC controller that I am using. I call this code each time i find a specific type of link and it appears that doing this many times is causing me to run out of memory. Maybe a solution would be to use a threadpool and limit the max number of threads, but how would I do that to this code? Here is the web crawler code that calls the webbrowser code: public static
