  1. POGUI not responding while fetching data
    text
    copied!<p>My application often fetch data from a webpage using WebRequest, but it isn't possible to click buttons etc while it's fetching. I've understood that I have to use threads/a backgroundworker, but I can't get it to work properly; it doesn't make the GUI more respondable. </p> <p>The code I want to apply some kind of threading on, so that it stops making my application unresponding:</p> <pre><code>public string SQLGet(string query) { string post = "q=" + query; WebRequest request = WebRequest.Create("http://test.com"); request.Timeout = 20000; request.Method = "POST"; byte[] bytes = Encoding.UTF8.GetBytes(post); request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = bytes.Length; Stream requestStream = request.GetRequestStream(); requestStream.Write(bytes, 0, bytes.Length); requestStream.Close(); WebResponse response = request.GetResponse(); requestStream = response.GetResponseStream(); StreamReader reader = new StreamReader(requestStream); string ret = reader.ReadToEnd(); reader.Close(); requestStream.Close(); response.Close(); return ret; } </code></pre> <hr> <p>Edit: Thank you, lc, I had tried something pretty similar to that. But my problem with using the backgroundworker like that is; how do I get the queryResult back to the function which called (in my case SQLGet, and in your case) StartQuery?</p> <p>In my example, the returned string is going to be used as a local variable in the void the string is called inside. </p> <p>And there may be many queries at the same time, so I don't want to risk assigning it to a global variable. </p>
 

Querying!
