  • how to get response from remote server

    - by ruhit
    I have made a desktop application in asp.net using c# that connecting with remote server.I am able to connect but how do i show that my login is successful or not. After that i want to retrieve data from the remote server..........so plz help me.I have written the below code..............is there any better way try { string strId = UserId_TextBox.Text; string strpasswrd = Password_TextBox.Text; ASCIIEncoding encoding = new ASCIIEncoding(); string postData = "UM_email=" + strId; postData += ("&UM_password=" + strpasswrd); byte[] data = encoding.GetBytes(postData); MessageBox.Show(postData); // Prepare web request... //HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://localhost/ruhit/basic_framework/index.php?menu=login=" + postData); HttpWebRequest myRequest =(HttpWebRequest)WebRequest.Create("http://www.facebook.com/login.php=" + postData); myRequest.Method = "POST"; myRequest.ContentType = "application/x-www-form-urlencoded"; myRequest.ContentLength = data.Length; Stream newStream = myRequest.GetRequestStream(); // Send the data. newStream.Write(data, 0, data.Length); MessageBox.Show("u r now connected"); HttpWebResponse response = (HttpWebResponse)myRequest.GetResponse(); // WebResponse response = myRequest.GetResponse(); StreamReader reader = new StreamReader(response.GetResponseStream()); string str = reader.ReadLine(); while (str != null) { str = reader.ReadLine(); MessageBox.Show(str); } reader.Close(); newStream.Close(); } catch { MessageBox.Show("error connecting"); }

  • Proper API Design for Version Independence?

    - by Justavian
    I've inherited an enormous .NET solution of about 200 projects. There are now some developers who wish to start adding their own components into our application, which will require that we begin exposing functionality via an API. The major problem with that, of course, is that the solution we've got on our hands contains such a spider web of dependencies that we have to be careful to avoid sabotaging the API every time there's a minor change somewhere in the app. We'd also like to be able to incrementally expose new functionality without destroying any previous third party apps. I have a way to solve this problem, but i'm not sure it's the ideal way - i was looking for other ideas. My plan would be to essentially have three dlls. APIServer_1_0.dll - this would be the dll with all of the dependencies. APIClient_1_0.dll - this would be the dll our developers would actual refer to. No references to any of the mess in our solution. APISupport_1_0.dll - this would contain the interfaces which would allow the client piece to dynamically load the "server" component and perform whatever functions are required. Both of the above dlls would depend upon this. It would be the only dll that the "client" piece refers to. I initially arrived at this design, because the way in which we do inter process communication between windows services is sort of similar (except that the client talks to the server via named pipes, rather than dynamically loading dlls). While i'm fairly certain i can make this work, i'm curious to know if there are better ways to accomplish the same task.

  • MD5CryptoServiceProvider ComputeHash Issues between VS 2003 and VS 2008

    - by owensoroke
    I have a database application that generates a MD5 hash and compares the hash value to a value in our DB (SQL 2K). The original application was written in Visual Studio 2003 and a deployed version has been working for years. Recently, some new machines on the .NET framework 3.5 have been having unrelated issues with our runtime. This has forced us to port our code path from Visual Studio 2003 to Visual Studio 2008. Since that time the hash produced by the code is different than the values in the database. The original call to the function posted in code is: RemoveInvalidPasswordCharactersFromHashedPassword(Text_Scrub(GenerateMD5Hash(strPSW))) I am looking for expert guidance as to whether or not the MD5 methods have changed since VS 2K3 (causing this point of failure), or where other possible problems may be originating from. I realize this may not be the best method to hash, but utimately any changes to the MD5 code would force us to change some 300 values in our DB table and would cost us a lot of time. In addition, I am trying to avoid having to redeploy all of the functioning versions of this application. I am more than happy to post other code including the RemoveInvalidPasswordCharactersFromHashedPassword function, or our Text_Scrub if it is necessary to recieve appropriate feedback. Thank you in advance for your input. Public Function GenerateMD5Hash(ByVal strInput As String) As String Dim md5Provider As MD5 ' generate bytes for the input string Dim inputData() As Byte = ASCIIEncoding.ASCII.GetBytes(strInput) ' compute MD5 hash md5Provider = New MD5CryptoServiceProvider Dim hashResult() As Byte = md5Provider.ComputeHash(inputData) Return ASCIIEncoding.ASCII.GetString(hashResult) End Function

  • How to Prevent PostBack Event Handler from Firing

    - by user331744
    I have a custom class (ServerSideValidator.vb) that validates user input on server side (it doesn't use any of the .NET built in validators, therefore Page.Validate() is not an option for me). I am calling the Validate() method on page.IsPostback event and the class performs without any problem My issue is, when validation fails (returns false), I want to stop the postback event handler from firing, but load the page along with all the controls and user-input values in them. If I do, Response.End(), the page comes up blank. I can programmatically instruct the page to go to the previous page (original form before postback), but it loses all user-inputs. I thought of creating a global boolean variable in the page code behind file and check the value before performing any postback method, but this approach takes away from my plan to provide all functionalities inside the class itself. The page object is being referenced to ServerSideValidator. Seems like all the postback related properties/variables I come across inside Page class are 'Readonly' and I can't assign value(s) to control/prevent postback event from firing. Any idiea on how I can accomplish this? Please let me know if you need further details

  • How can I automatically highlight a specific character in link text using JQuery + CSS?

    - by Chris McCall
    I'm adding hotkeys to a web application in order to enable keyboard shortcuts for our CSRs to use, to reduce injury and increase calls-per-hour. I'm using an ASP.net UserControl to inject javascript into the page and it's working great. I want the control to "just work", so that when hotkeys are assigned, using a declarative syntax, if the hotkeyed letter exists in the link text, it will be highlighted automatically, so the developer doesn't have to do anything, and also to maintain consistency in visual cues. Here's the code to assign hotkeys, if it matters: <uc:HotKeysControl ID="theHotkeys" runat="server" Visible="true"> <uc:HotKey ControlName="AccStatus$btnInvoiceEverBill" KeyCode="ctrl+v" /> <uc:HotKey ControlName="AccStatus$btnRefund" KeyCode="ctrl+u" /> <uc:HotKey ControlName="thirdControl" KeyCode="ctrl+p" /> </uc:HotKeysControl> I want something like: <a href="whatever" name="thirdControl">Make a <span class=hotkey">P</span>ayment</a> ...but I'm not married to the idea of injecting a <span/> in there if there's a better way. How can I do this in CSS or JQuery? Is there a way to pass in a letter to a CSS style and have it change the color of the text displayed? Should I generate javascript to highlight the text when the page loads? What would/did you do in this situation?

  • FormsAuthentication authCookie is null only for some users

    - by mbalkema
    I am experiencing a strange problem with asp.net forms authentication. This problem only occurs for 3 users out of 30+ users that have successfully logged in. I am using very basic auth code that I have used many times and have never seen this problem. After the users successfully authenticates and the auth cookie is created, cookie added, and response.redirect to FormsAuthentication.GetRedirect(userid, false) is called. The Application_AuthenticateRequest method in Global.asax is hit. // Extract the forms authentication cookie string cookieName = FormsAuthentication.FormsCookieName; HttpCookie authCookie = Context.Request.Cookies[cookieName]; if (null == authCookie) { // There is no authentication cookie. return; } So immediately after a "good" cookie is saved and the redirect occurs the cookie is null. I have run the code through the debugger and the cookie is only null on these 3 users. But the cookie looks the same as the cookie for the many users that login successfully. Any ideas? This is standard code that should just work.

  • jQuery code works for console but not in-page.

    - by justSteve
    I have a form element defined as: <div class="field"> <div class="name"> <label for="User_LastName"> Last name: <span class="asterisk">*</span></label> </div> <div class="value"> <%= Html.TextBox("User.LastName", Model.LastName)%> <%= Html.ValidationMessage("User.LastName")%> </div> </div> and a jQuery selector that is supposed to detect when the input gets focus and highlight the parent: $("input").focus(function() { //watching for an event where an input form comes into focus $(this) .parent() .addClass("curFocus") .children("div") .toggle(); }); If i paste this code into firebug's console - things work as planned. However, i'm running this from a 'RenderPartial' .net mvc page. Other jQuery code sitting within the same $(document).ready(function() { block work correctly. The form uses html helpers to generate the inputs which might complicate the process somewhat - but even so... i'm seeing correct behavior when that code's in console but not in a 'real-time' page. How do i troubleshoot this?

  • MS Exam 70-536 - How to throw and handle exception from thread?

    - by Max Gontar
    Hello! In MS Exam 70-536 .Net Foundation, Chapter 7 "Threading" in Lesson 1 Creating Threads there is a text: Be aware that because the WorkWithParameter method takes an object, Thread.Start could be called with any object instead of the string it expects. Being careful in choosing your starting method for a thread to deal with unknown types is crucial to good threading code. Instead of blindly casting the method parameter into our string, it is a better practice to test the type of the object, as shown in the following example: ' VB Dim info As String = o as String If info Is Nothing Then Throw InvalidProgramException("Parameter for thread must be a string") End If // C# string info = o as string; if (info == null) { throw InvalidProgramException("Parameter for thread must be a string"); } So, I've tried this but exception is not handled properly (no console exception entry, program is terminated), what is wrong with my code (below)? class Program { static void Main(string[] args) { Thread thread = new Thread(SomeWork); try { thread.Start(null); thread.Join(); } catch (InvalidProgramException ex) { Console.WriteLine(ex.Message); } finally { Console.ReadKey(); } } private static void SomeWork(Object o) { String value = (String)o; if (value == null) { throw new InvalidProgramException("Parameter for "+ "thread must be a string"); } } } Thanks for your time!

  • Extend legacy site with another server-side programming platform best practice

    - by Andrew Florko
    Company I work for have a site developed 6-8 years ago by a team that was enthusiastic enough to use their own private PHP-based CMS. I have to put dynamic data from one intranet company database on this site in one week: 2-3 pages. I contacted company site administrator and she showed me administrative part - CMS allows only to insert html blocks & manage site map (site is deployed on machine that is inside company & fully accessible & upgradeable). I'm not a PHP-guy & I don't want to dive into legacy hardly-who-ever-heard-about CMS engine I also don't want to contact developers team, 'cos I'm not sure they are still present and capable enough to extend this old days site and it'll take too much time anyway. I am about to deploy helper asp.net site on IIS with 2-3 pages required & refer helper site via iframe from present site. New pages will allow to download some dynamic content from present site also. Is it ok and what are the pitfalls with iframe approach?

  • Where to store: User connection information?

    - by TomTom
    ;) I am writing a .NET application wher ethe user connects to a given server. ALl information within the application is stored in the server. But I want / need to store the following information for the user: The server he connected to last The username he used to connect last (and no, no password, never ever). Any idea where to store this best? the application config file is not sensible (user != admin, application.config is write protected for him). So, my options are: In the registry. 2 keys under my own subkey. In a sort of ini file, stored in the user's data directory (AppData). This would possibly also allow later expansion (into like saving more information, some of which may not fit into the registry). Anyone a tip? Other alternatives? I tend so far to go for the AppData directory with my own subfolder - simply because it is a nice preparation for later to keep like a local copy of configuration etc.

  • Why wouldn't an embedded silverlight control work in a page?

    - by rsteckly
    Hi, I have a silverlight application project in my solution. The other project is a web application project that has a .xap file in ClientBin. When I created the silverlight project, it asked if I wanted the asp.net application to host it (and I said yes). In the root directory, there is a test page for the silverlight control. That loads the control. In another directory, I insert the SAME asp markup to get the silverlight control to launch again. Nothing happens. Why would the silverlight launch on one page and not on the other? Can people help point me to documentation about dependencies that I might not know about? I've put a reference to Silverlight.js on the page as well. Here's the markup: <div id="silverlightControlHost"> <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%"> <param name="source" value="../ClientBin/Editor.xap"/> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="3.0.40818.0" /> <param name="autoUpgrade" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40818.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style:none"/> </a> </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div> </div>

  • How can I include DBNull as a value in my strongly typed dataset?

    - by Beska
    I've created a strongly typed dataset (MyDataSet) in my .NET app. For the sake of simplicity, we'll say it has one DataTable (MyDataTable), with one column (MyCol). MyCol has its DataType property set to "System.Int32", and its AllowDBNull property set to "true". I'd like to manually create a new row, and add it to this dataset. I create the row without a problem, with something like: MyDataSet.MyDataTableRow myRow = MySimpleDataSet.MyDataTable.NewItemRow(); Fine. However, when I try to set the value to DBNull: myRow.MyCol = DBNull.Value; I'm told that I can't do it...that it can't cast that to an int. This makes sense, in a way, since I've defined it to be an int...but then how can I get DBNull in there? Am I not supposed to be able to have DBNull in there? Isn't that what the AllowDBNull property is for? I'm obviously missing something fundemental. Can someone help explain what it is? EDIT: I also tried entering "int?" as the DataType, but Visual Studio throws an error when I enter it, saying that "Column requires a valid DataType."

  • UpdatePanel reloads the whole page

    - by Emil D
    Hi.I'm building an asp.net cutom control inside which I have two dropdownlists: companyIdSelection and productFamilySelection.I populate the companyIdSelection at Page_Load and in order to populate the productFamilySelection depending on the selected item in companyIdSelection.I'm using UpdatePanels to achieve this, but for some reason every time I update companyIdSelection Page_Load is being called ( which as far as I know should happen only when the entire page is reloaded ), the list is being reloaded again and the item the user selected is lost( the selected item is always the top one ).Here's the code <asp:UpdatePanel ID="updateFamilies" runat="server" UpdateMode="Always"> <ContentTemplate> Company ID:<br> <br></br> <asp:DropDownList ID="companyIdSelection" runat="server" AutoPostBack="True" OnSelectedIndexChanged="companyIdSelection_SelectedIndexChanged"> </asp:DropDownList> <br></br> Product Family: <br></br> <asp:DropDownList ID="productFamilySelection" runat="server" AutoPostBack="True" onselectedindexchanged="productFamilySelection_SelectedIndexChanged"> </asp:DropDownList> <br> </ContentTemplate> </asp:UpdatePanel> protected void Page_Load(object sender, EventArgs e) { this.companyIdSelection.DataSource = companyIds(); //companyIds returns the object containing the initial data items this.companyIdSelection.DataBind(); } protected void companyIdSelection_SelectedIndexChanged(object sender, EventArgs e) { // Page_Load is called again for some reason before this method is called, so it // resets the companyIdSelection EngDbService s = new EngDbService(); productFamilySelection.DataSource = s.getProductFamilies(companyIdSelection.Text); productFamilySelection.DataBind(); } Also, I tried setting the UpdateMode of the UpdatePanel to "Conditional" and adding an asyncpostback trigger but the result was the same. What am I doing wrong? PS: I fixed the updating problem, by using Page.IsPostBack in the Page_Load method, but I would still want to avoid a full postback if possible

  • What is better: Developing a Web project in MVC or N -Tier Architecture?

    - by Starx
    I have asked a similar question before and got an convincing answer as well? http://stackoverflow.com/questions/2843311/what-is-difference-of-developing-a-website-in-mvc-and-3-tier-or-n-tier-architectu Due to the conclusion of this question I started developing projects in N-tier Architecture. Just about an hour ago, I asked another question, about what is the best design pattern to create interface? There the most voted answer is suggesting me to use MVC architecture. http://stackoverflow.com/questions/2930300/what-is-the-best-desing-pattern-to-design-the-interface-of-an-webpage Now I am confused, First post suggested me that both are similar, just a difference that in N-tier, the tier are physically and logically separated and one layer has access to the one above and below it but not all the layers. I think ASP.net used 3 Tier architecture while developing applications or Web applications. Where as frameworks like Zend, Symphony they use MVC. I just want to stick to a pattern that is best suitable for WebProject Development? May be this is a very silly confusion? But if someone could clear this confusion, that would be very greatful?

  • Large Product catalog with statistics - alternatives to Sql Server?

    - by Eric P
    I am building UI for a large product catalog (millions of products). I am using Sql Server, FreeText search and ASP.NET MVC. Tables are normalized and indexed. Most queries take less then a second to return. The issue is this. Let's say user does the search by keyword. On search results page I need to display/query for: First 20 matching products (paged, sorted) Total count of matching products for paging List of stores only of matching products List of brands only of matching products List of colors only of matching products Each query takes about .5 to 1 seconds. Altogether it is like 5 seconds. I would like to get the whole page to load under 1 second. There are several approaches: Optimize queries even more. I already spent a lot of time on this one, so not sure it can be pushed further. Load products first, then load the rest of the information using AJAX. More like a workaround. Will need to revise UI. Re-organize data to be more Report friendly. Already aggregated a lot of fields. I checked out several similar sites. For ex. zappos.com. Not only they display the same information as I would like in under 1 second, but they also include statistics (number of results in each category). The following is the search for keyword "white" http://www.zappos.com/white How do sites like zappos, amazon make their results, filters and stats appear almost instantly?

  • Find window with specific text for a Process

    - by Axarydax
    Hello, I'm trying to find if a window with specific has been open by a Process. That process spawns multiple windows, and I need to check them all. I have no trouble finding the process, with foreach (Process p in Process.GetProcesses()) { if (p.MainModule.FileName.ToLower().EndsWith("foo.exe")) FindChildWindowWithText(p); //do work the problem is what to do next. I cannot use Process' MainWindowText, because it changes with whichever window is activated. Then I've tried to use Windows function EnumChildWindows and GetWindowText, but I am not sure if I'm passing a correct handle to EnumChildWindows. The EnumChildWindows works as expected when passed MainWindowHandle, but of course the MainWindowHandle changes with active window. So I passed Process.Handle, but I get different handles and different results when switching the app's windows. (I understand that EnumChildWindows returns handles to not only windows, but controls in .net speak, that's no problem if I could get the caption of the window too) Maybe I am doing this the wrong way and I need a different approach - again, my problem is as simple as finding a window with text that matches specific regular expression. So I would probably need a function that enumerates all windows, that are visible in the taskbar or so. Thanks

  • What collection object is appropriate for fixed ordering of values?

    - by makerofthings7
    Scenario: I am tracking several performance counters and have a CounterDescription[] correlate to DataSnapshot[]... where CounterDescription[n] describes the data loaded within DataSnapshot[n]. I want to expose an easy to use API within C# that will allow for the easy and efficient expansion of the arrays. For example CounterDescription[0] = Humidity; DataSnapshot[0] = .9; CounterDescription[1] = Temp; DataSnapshot[1] = 63; My upload object is defined like this: Note how my intent is to correlate many Datasnapshots with a dattime reference, and using the offset of the data to refer to its meaning. This was determined to be the most efficient way to store the data on the back-end, and has now reflected itself into the following structure: public class myDataObject { [DataMember] public SortedDictionary<DateTime, float[]> Pages { get; set; } /// <summary> /// An array that identifies what each position in the array is supposed to be /// </summary> [DataMember] public CounterDescription[] Counters { get; set; } } I will need to expand each of these arrays (float[] and CounterDescription[] ), but whatever data already exists must stay in that relative offset. Which .NET objects support this? I think Array[] , LinkedList<t>, and List<t> Are able to keep the data fixed in the right locations. What do you think?

  • How do I put my return data from an asmx into JSON?

    - by jphenow
    I want to return an array of javascript objects from my asp.net asmx file. ie. variable = [ { *value1*: 'value1', *value2*: 'value2', ..., }, { . . } ]; I seem have been having trouble reaching this. I'd put this into code but I've been hacking away at it so much it'd probably do more harm than good in having this answered. Basically I am using a web service to find names as people type the name. I'd use a regular text file or something but its a huge database that's always changing - and don't worry I've indexed the names so searching can be a little snappier - but I would really prefer to stick with this method and just figure out how to get usable JSON back to javascript. I've seen a few that sort of attempt to describe how one would approach this but I honestly think microsofts articles are damn near unreadable. Thanks in advance for assistance. EDIT: I'm using the $.ajax() function from jQuery - I've had it working but it seems like I was doing it in bad practice not returning and using actual JSON. Previously I'd take a string back and insert it into html to use the variable it set - very roundabout.

  • Is it possible to persist two profiles with the Profile Provider Model?

    - by NickGPS
    I have a website that needs to store two sets of user data into separate data stores. The first set of data is used by the SiteCore CMS and holds information about the user. The second set of data is used by a personalisation application that stores its own user data. The reason they aren't stored together in the same profile object is because the personalisation application is used across multiple websites that do not all use SiteCore. I am able to create multiple Profile Providers - I currently have one from SiteCore and a custom provider that I have written and these both work in isolation. The problem exists when you try to configure both in the same web.config file. It seems you can only specify a single Profile object in the web.config file, rather than one for each provider. This means that regardless of which provider is being used the .Net framework sends through the profile object that is specified in the "inherits" parameter in the profile section of the web.config file. My questions are - Is it possible to specify a different Profile object for each Profile Provider? If so, how and where is this specified? Thanks, Nick

  • How can I take advantage of IObservable/IObserver to get rid of my "god object"?

    - by Will
    In a system I'm currently working on, I have many components which are defined as interfaces and base classes. Each part of the system has some specific points where they interact with other parts of the system. For example, the data readying component readies some data which eventually needs to go to the data processing portion, the communications component needs to query different components for their status for relaying to the outside, etc. Currently, I glue these parts of the system together using a "god object", or an object with intimate knowledge of different parts of the system. It registers with events over here and shuttles the results to methods over there, creates a callback method here and returns the result of that method over there, and passes many requests through a multi-threaded queue for processing because it "knows" certain actions have to run on STA threads, etc. While its convenient, it concerns me that this one type knows so much about how everybody else in the system is designed. I'd much prefer a more generic hub that can be given instances which can expose events or methods or callbacks or that can consume these. I've been seeing more about the IObservable/IObserver features of the reactive framework and that are being rolled into .NET 4.0 (I believe). Can I leverage this pattern to help replace my "god object"? How should I go about doing this? Are there any resources for using this pattern for this specific purpose?

  • Accomodating Multiple DLL Versions

    - by shadeseeker
    I have an application that uses a Microsoft DLL (Microsoft.ComponentStudio.ComponentPlatformImplementation.dll) which is used for OS deployment and accessing the catalog files. Version 6.0.0.0 is specific to the Windows Server 2008 catalog files. The newer version 6.1.0.0 is specific to Windows Server 2008 R2 catalog files. Attempting to access a catalog file with the incorrect version results in an exception. My application (VB.NET using VS2005) needs to be able to access either version of these catalogs - I'd be happy with two executables (one for each catalog version) but obviously I don't want to maintain two sets of source code for each. Specifying both sets of DLLs in the project reference is not possible as the DLL names are identical. I'd rather not have to manually add and remove the DLL references each time I want to a build. As far as I know the interfaces etc are effectively identical between the two. I've read a few articles here and elsewhere about bindingRedirect, Assembly.Load etc but none seem to be bearing fruit. Any guidance on the best path to follow would be greatly appreciated. Thanks.
