  • Receicing POST data in ASP.NET

    - by grast
    Hi, I want to use ASP for code generation in a C# desktop application. To achieve this, I set up a simple host (derived from System.MarshalByRefObject) that processes a System.Web.Hosting.SimpleWorkerRequest via HttpRuntime.ProcessRequest. This processes the ASPX script specified by the incoming request (using System.Net.HttpListener to wait for requests). The client-part is represented by a System.ComponentModel.BackgroundWorker that builds the System.Net.HttpWebRequest and receives the response from the server. A simplified version of my client-part-code looks like this: private void SendRequest(object sender, DoWorkEventArgs e) { // create request with GET parameter var uri = "http://localhost:9876/test.aspx?getTest=321"; var request = (HttpWebRequest)WebRequest.Create(uri); // append POST parameter request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; var postData = Encoding.Default.GetBytes("postTest=654"); var postDataStream = request.GetRequestStream(); postDataStream.Write(postData, 0, postData.Length); // send request, wait for response and store/print content using (var response = (HttpWebResponse)request.GetResponse()) { using (var reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8)) { _processsedContent = reader.ReadToEnd(); Debug.Print(_processsedContent); } } } My server-part-code looks like this (without exception-handling etc.): public void ProcessRequests() { // HttpListener at http://localhost:9876/ var listener = SetupListener(); // SimpleHost created by ApplicationHost.CreateApplicationHost var host = SetupHost(); while (_running) { var context = listener.GetContext(); using (var writer = new StreamWriter(context.Response.OutputStream)) { // process ASP script and send response back to client host.ProcessRequest(GetPage(context), GetQuery(context), writer); } context.Response.Close(); } } So far all this works fine as long as I just use GET parameters. But when it comes to receiving POST data in my ASPX script I run into trouble. For testing I use the following script: // GET parameters are working: var getTest = Request.QueryString["getTest"]; Response.Write("getTest: " + getTest); // prints "getTest: 321" // don't know how to access POST parameters: var postTest1 = Request.Form["postTest"]; // Request.Form is empty?! Response.Write("postTest1: " + postTest1); // so this prints "postTest1: " var postTest2 = Request.Params["postTest"]; // Request.Params is empty?! Response.Write("postTest2: " + postTest2); // so this prints "postTest2: " It seems that the System.Web.HttpRequest object I'm dealing with in ASP does not contain any information about my POST parameter "postTest". I inspected it in debug mode and none of the members did contain neither the parameter-name "postTest" nor the parameter-value "654". I also tried the BinaryRead method of Request, but unfortunately it is empty. This corresponds to Request.InputStream==null and Request.ContentLength==0. And to make things really confusing the Request.HttpMethod member is set to "GET"?! To isolate the problem I tested the code by using a PHP script instead of the ASPX script. This is very simple: print_r($_GET); // prints all GET variables print_r($_POST); // prints all POST variables And the result is: Array ( [getTest] = 321 ) Array ( [postTest] = 654 ) So with the PHP script it works, I can access the POST data. Why does the ASPX script don't? What am I doing wrong? Is there a special accessor or method in the Response object? Can anyone give a hint or even know how to solve this? Thanks in advance.

  • Card game in python

    - by matt1024
    What is the best way to store the cards and suits in python so that I can hold a reference to these values in another variable? For example, if I have a list called hand (cards in players hand), how could I hold values that could refer to the names of suits and values of specific cards, and how would these names and values of suits and cards be stored?

  • How to ignore expired certificates from outside a Java application?

    - by Creepy Gnome
    We have a Java application that we need to ignore an expired self-signed cert, however we cannot modify the code to do this. I wondering if there was a System Property or environment variable that we could provide at start up that would allow us to have all expired cert's ignored for now, or even be more specific and provide externally the specific cert that we would like to have the expiration ignored. Anyone have any ideas that would work?

  • Prolific USB-to-Serial Comm Port significantly slower under Windows 7 comparing to Windows XP

    - by Dmitry S
    I am using a Prolific USB-to-Serial adapter based on the Prolific chip to use with a device on serial port. I have the latest version of the driver installed: 1.3.0 (2010-7-15). When I use my device with this adapter on my main Windows 7 (32bit) system it takes 8-9 seconds to send a command through to the device. However, when I do the same thing on a different Windows XP system (an old laptop I borrowed for testing) it only takes 2-3 seconds. I have made sure that the port settings and other variables are the same between systems. I also tested on a third laptop (also running Windows 7) and again got a significant delay. So the question is if anyone else experienced the same problem and found a solution. I would like to avoid moving to an XP system for what I need to achieve so that's my last option.

  • What's the best way to structure this Linq-to-Events Drag & Drop code?

    - by Rob Fonseca-Ensor
    I am trying to handle a drag & drop interaction, which involves mouse down, mouse move, and mouse up. Here is a simplified repro of my solution that: on mouse down, creates an ellipse and adds it to a canvas on mouse move, repositions the ellipse to follow the mouse on mouse up, changes the colour of the canvas so that it's obvious which one you're dragging. var mouseDown = Observable.FromEvent<MouseButtonEventArgs>(canvas, "MouseLeftButtonDown"); var mouseUp = Observable.FromEvent<MouseButtonEventArgs>(canvas, "MouseLeftButtonUp"); var mouseMove = Observable.FromEvent<MouseEventArgs>(canvas, "MouseMove"); Ellipse ellipse = null; var q = from start in mouseDown.Do(x => { // handle mousedown by creating a red ellipse, // adding it to the canvas at the right position ellipse = new Ellipse() { Width = 10, Height = 10, Fill = Brushes.Red }; Point position = x.EventArgs.GetPosition(canvas); Canvas.SetLeft(ellipse, position.X); Canvas.SetTop(ellipse, position.Y); canvas.Children.Add(ellipse); }) from delta in mouseMove.Until(mouseUp.Do(x => { // handle mouse up by making the ellipse green ellipse.Fill = Brushes.Green; })) select delta; q.Subscribe(x => { // handle mouse move by repositioning ellipse Point position = x.EventArgs.GetPosition(canvas); Canvas.SetLeft(ellipse, position.X); Canvas.SetTop(ellipse, position.Y); }); the XAML is simply <Canvas x:Name="canvas"/> There's a few things I don't like about this code, and I need help refactoring it :) First of all: the mousedown and mouseup callbacks are specified as side effects. If two subscriptions are made to q, they will happen twice. Second, the mouseup callback is specified before the mousemove callback. This makes it a bit hard to read. Thirdly, the reference to the ellipse seems to be in a silly place. If there's two subscriptions, that variable reference will get overwritten quite quickly. I'm sure that there should be some way we can leverage the let keyword to introduce a variable to the linq expression that will mean the correct ellipse reference is available to both the mouse move and mouse up handlers How would you write this code?

  • How much should a Systems Administrator be making?

    - by Curtis
    Hello, I'm a Sys Admin for a small (but successful and growing) company (~60 employees). I've got roughly 5-6 years of actual sys admin experience, plus another 5+ years of lower level work in the industry. I'm responsible for most everything above a helpdesk level in the company (server[windows]/network[cisco]/firewall/SAN[emc] setup/configuration/maintenance/troubleshooting), lead many projects, analyze system data -- I'm sure you've heard it all before...I have a bunch of certs, most are just "nice to have", but the ones that actually apply to my role are CCNA, MSCE, VCP (VMware). If things go wrong, I'm first in line to resolve the issue. I'm not management (no one reports to me). I've seen many of these sorts of questions online before, and I know the typical response is "too many variables, depends on location, industry type" etc etc. I'm just wondering (ballpark) what I should be looking for. I've tried to give as much detail as I can, but if I'm missing something, I'd be glad to post it. Thanks anyone.

  • Trouble recovering MySQL InnoDB database after server crash

  • Unknown MySQL server host - connection problem

    - by Zukas
    I am new to databases and I have been asked to look at a few tables and see how many records they have and some other information. I cannot access phpMyAdmin through cPanel, which is how I've always done it on my own server. I decided to download MySQL Workbench. I enter in all the information is asks: Hostname: mysite.startlogicmysql.com Port: 3306 Username: user. I press connect and get this Unknown MySQL server host 'mysite.startlogicmysql.com' (11004) Am I using the wrong hostname? I've seen a server name, a hostname in the server variables list which is something like custsql.eigbox.net and the server itself is custsql.eigbox.net In both cases the custsql is a little different than what I posted. I am not sure which one to use. If there is anything else anyone needs to know I can tell you. Tanks.

  • Fixing VBSCRIPT inaccurate mathematical results due to rounding

    - by jay
    Try running this in a .VBS file MsgBox(545.14-544.94) You get a neat little answer of 0.199999999999932! This rounding issue also occurs unfortunately in Sin(2 * pi) since VB can only ever see the (user defined) variable pi as accurate as 3.14159265358979. Is rounding it manually (and loosing accuracy) the only way to improve the result? What is the most effective way of dealing with this kind of problem?
