  • error while updating a database in ASP.NET

    - by Viredae
    I am having trouble updating an SQL database, the problem is not that it doesn't update at all, but that particular parameters are being updated while the others are not. here is the code for updating the parameters: string EditRequest = "UPDATE Requests SET Description = @Desc, BJustif = @Justif, Priority = @Priority, Requested_System = @Requested, Request_Status = @Stat WHERE"; EditRequest += " Req_ID=@ID"; SqlConnection Submit_conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["DBConn"].ConnectionString); SqlCommand Submit_comm = new SqlCommand(EditRequest, Submit_conn); Submit_comm.Parameters.AddWithValue("@ID", Request.QueryString["reqid"]); Submit_comm.Parameters.AddWithValue("@Desc", DescBox.Text); Submit_comm.Parameters.AddWithValue("@Justif", JustifBox.Text); Submit_comm.Parameters.AddWithValue("@Priority", PriorityList.SelectedValue); Submit_comm.Parameters.AddWithValue("@Requested", RelatedBox.Text); Submit_comm.Parameters.AddWithValue("@Stat", 1); Submit_conn.Open(); Submit_comm.ExecuteNonQuery(); Submit_comm.Dispose(); Submit_comm = null; Submit_conn.Close(); get_Description(); Page.ClientScript.RegisterStartupScript(this.GetType(), "Refresh", "ReloadPage();", true); this function is called by a button on a pop-up form which shows the parameters content that is being changed in a text box which is also used to submit the changes back to the database, but when I press submit, the parameters which are displayed on the form don't change, I can't find any problem wit the code, even though I've compared it to similar code which is working fine. In case you need to, here is one of the text boxes I'm using to display and edit the content: <asp:TextBox ID="JustifBox" TextMode="MultiLine" runat="server" Width="250" Height="50"></asp:TextBox> What exactly is wrong with the code?

  • .NET Web Service Proxy is adding special characters in XML

    - by xkingpin
    My web service proxy seems to be adding special characters like "*" and "#" etc. within the xml nodes. My proxy created lists using arrays of objects. I am trying to create a generic list and then doing list.ToArray() to set the proxy MyProxyObject[] object. Is this the cause of the problem I am having? I plan on running fiddler on the request later but it is over SSL and I do not have access to the URL at the moment. Here is an example of the XML that is generated: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> * <soap:Body> o I'm a little concerned because the special characters are even occuring before the array nodes

  • ASP.NET ObjectDataSource Sorting Twice

    - by user204588
    Hello, I'm working with some existing code uses an objectDataSource and that calls a sort method inside a DLL that I don't have access to. I'm trying to add a custom field to sort and I basically want to re-sort after the initial sort. I don't know if this can be done but before the GridView is displayed, I need to intercept the code and sort the way I want to sort. Any ideas? I'm lost.

  • Call .NET Webservice with Android

    - by Lasse P
    Hi, I know this question has been asked here before, but I don't think those answers were adequate for my needs. We have a SOAP webservice that is used for an iPhone application, but it is possible that we need an Android specific version or a proxy of the service, so we have the option to go with either SOAP or JSON. I have a few concerns about both methods: SOAP solution: Is it possible to generate java source code from a WSDL file, if so, will it include some kind of proxy class to invoke the webservice and will it work in the Android environment at all? Google has not provided any SOAP library in Android, so i need to use 3rd party, any suggestion? What about the performance/overhead with parsing and transmitting SOAP xml over the wire versus the JSON solution? JSON solution: There is a few classes in the Android sdk that will let me parse JSON, but does it support generic parsing, like if I want the result to be parsed as a complex type? Or would I need to implement that myself? I have read about 2 libraries before here on Stackoverflow, GSON an Jackson. What is the difference performance and usability (from a developers perspective) wise? Do you guys have any experince with either of those libraries? So i guess the big question is, what method to go with? I hope you can help me out. Thanks in advance :-)

  • ASP.NET enum dropdownlist validation

    - by Arun Kumar
    I have got a enum public enum TypeDesc { [Description("Please Specify")] PleaseSpecify, Auckland, Wellington, [Description("Palmerston North")] PalmerstonNorth, Christchurch } I am binding this enum to drop down list using the following code on page_Load protected void Page_Load(object sender, EventArgs e) { if (TypeDropDownList.Items.Count == 0) { foreach (TypeDesc newPatient in EnumToDropDown.EnumToList<TypeDesc>()) { TypeDropDownList.Items.Add(EnumToDropDown.GetEnumDescription(newPatient)); } } } public static string GetEnumDescription(Enum value) { FieldInfo fi = value.GetType().GetField(value.ToString()); DescriptionAttribute[] attributes = (DescriptionAttribute[])fi.GetCustomAttributes(typeof(DescriptionAttribute), false); if (attributes != null && attributes.Length > 0) return attributes[0].Description; else return value.ToString(); } public static IEnumerable<T> EnumToList<T>() { Type enumType = typeof(T); // Can't use generic type constraints on value types, // so have to do check like this if (enumType.BaseType != typeof(Enum)) throw new ArgumentException("T must be of type System.Enum"); Array enumValArray = Enum.GetValues(enumType); List<T> enumValList = new List<T>(enumValArray.Length); foreach (int val in enumValArray) { enumValList.Add((T)Enum.Parse(enumType, val.ToString())); } return enumValList; } and my aspx page use the following code to validate <asp:DropDownList ID="TypeDropDownList" runat="server" > </asp:DropDownList> <asp:RequiredFieldValidator ID="TypeRequiredValidator" runat="server" ControlToValidate="TypeDropDownList" ErrorMessage="Please Select a City" Text="<img src='Styles/images/Exclamation.gif' />" ValidationGroup="city"></asp:RequiredFieldValidator> But my validation is accepting "Please Specify" as city name. I want to stop user to submit if the city is not selected.

  • Feedback on Optimizing C# NET Code Block

    - by Brett Powell
    I just spent quite a few hours reading up on TCP servers and my desired protocol I was trying to implement, and finally got everything working great. I noticed the code looks like absolute bollocks (is the the correct usage? Im not a brit) and would like some feedback on optimizing it, mostly for reuse and readability. The packet formats are always int, int, int, string, string. try { BinaryReader reader = new BinaryReader(clientStream); int packetsize = reader.ReadInt32(); int requestid = reader.ReadInt32(); int serverdata = reader.ReadInt32(); Console.WriteLine("Packet Size: {0} RequestID: {1} ServerData: {2}", packetsize, requestid, serverdata); List<byte> str = new List<byte>(); byte nextByte = reader.ReadByte(); while (nextByte != 0) { str.Add(nextByte); nextByte = reader.ReadByte(); } // Password Sent to be Authenticated string string1 = Encoding.UTF8.GetString(str.ToArray()); str.Clear(); nextByte = reader.ReadByte(); while (nextByte != 0) { str.Add(nextByte); nextByte = reader.ReadByte(); } // NULL string string string2 = Encoding.UTF8.GetString(str.ToArray()); Console.WriteLine("String1: {0} String2: {1}", string1, string2); // Reply to Authentication Request MemoryStream stream = new MemoryStream(); BinaryWriter writer = new BinaryWriter(stream); writer.Write((int)(1)); // Packet Size writer.Write((int)(requestid)); // Mirror RequestID if Authenticated, -1 if Failed byte[] buffer = stream.ToArray(); clientStream.Write(buffer, 0, buffer.Length); clientStream.Flush(); } I am going to be dealing with other packet types as well that are formatted the same (int/int/int/str/str), but different values. I could probably create a packet class, but this is a bit outside my scope of knowledge for how to apply it to this scenario. If it makes any difference, this is the Protocol I am implementing. http://developer.valvesoftware.com/wiki/Source_RCON_Protocol

  • How does .NET repaint controls?

    - by serhio
    Say I have a custom Label that I paint in my way. As lite example we have the code: Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs) ' MyBase.OnPaint(e) DO NOT USE ' Dim f As Font = Me.Font Dim g As Graphics = e.Graphics Dim textRect As Rectangle = New Rectangle(Me.Location, Me.Size) Using br As New SolidBrush(Me._TextColor) g.DrawString(_Text, f, br, textRect) End Using End Sub maybe this example is useless, because does not bring different behavior that a simple label, but it just for example. Now, the problem is that if this label moves the ancient label area will not be updated, and the old text will remain until the parent will be invalidated. So the question is: How to invalidate the former control region?

  • Sending out 20,000+ emails with asp.net

    - by Kyle
    I am writing an application that will need to send a massive amount of emails to our students who will be selected from our database (each email will be personalized to the extent that will include their name, course of study etc...so needs to be sent one at a time). I could do this looping over an SmtpClient, but I'm afraid that with the numbers I'm trying to send, I'll ultimately run into timeout issues or my thread being killed because of lack of machine resources. At this point I'm just looking for suggestions of a better way to handle this, or if looping over SmtpClient is an ok solution, how I should go about handling it to prevent what I posted above. Would a web service be a better alternative? Please advise, TIA

  • Generic JSON parser in .NET / WPF?

    - by niklassaers
    I've read lots of tutorials on how to deserialize a JSON object to an object of a particular using DataContractJsonSerializer. However, I'd like to deserialize my object to a Dictionary consisting of either Strings, Arrays or Dictionaries, such as System.Json does with SilverLight when I say JsonObject.Parse(myJSONstring). Is there an equivalent to System.Json that I can use in my WPF project? (just a short background: I'm fetching JSON objects that have way to much info, and I just want to use a little bit to fill out a String array) Cheers Nik

  • vb.net creating and using namespace

    - by tridat
    I've googled for creation of namespaces and found some very useful examples, what these examples didn't have is how do I compile and implement my created namespace on my system so I can include it from my various applications. So for example, if I create a namespace to load a config file from my application path and insert it to an array, Do i need to include the namespace on any project I use or is there a way to make it part of my environment?

  • Confirm box always displays first (javascript, jQuery, .Net)

    - by Jan-Frederik Carl
    Hello, I have a jQuery-Script to accomplish the following tasks: if a gridview in my form contains a row with a certain id, it has to be marked red. a confirm dialogue has to pop up to ask the user if he wants to do this or that. I built this code: if (response == "EntryInList") { $('#entryListContainer div table tbody tr').each(function() { if ($(this).attr('id') == 'entry_' + $('#<%= txtProductNumber.ClientID %>').val()) { $(this).css("color", "red"); } } ); if (!confirm("Entry already exists. Really overwrite?")) { jQuery('#<%= txtProductNumber.ClientID %>').val(''); jQuery('#<%= txtCount.ClientID %>').val(''); jQuery('#<%= txtProductNumber.ClientID %>').focus(); return false; } } As a result, the confirm box pops up first, without the row being turned red. Only after using the box, it becomes red. How would I get the row to be turned red at once? Another of my problems is that the confirm box denies my page to be scrolled down. But I would like to do this if the gridview is longer than the entire page.

  • testing the controller in asp.net mvc

    - by csetzkorn
    Hi, I would like to test the validation of submitted DTO. This is the bare bone of a controller create action: [AcceptVerbs(HttpVerbs.Post)] public RedirectToRouteResult Create(SomeDTO SomeDTO) { SomeObject SomeObject = null; try { SomeObject = this.RepositoryService.getSomeObjectRepository().Create(SomeDTO, this.RepositoryService); } catch (BrokenRulesException ex) { ex.AddModelStateErrors(ModelState, "Model"); } catch (Exception e) { ModelState.AddModelError("Exception", e.Message); } TempData["ViewData"] = ViewData; TempData["SomeDTO "] = SomeDTO; return ModelState.IsValid ? RedirectToAction("SomeObjectDetail", new { Id = SomeObject.Id }) : RedirectToAction("Form"); } The mechanics , although not relevant, is as follows: I have a strongly typed view = form which submits a dto to this action which either returns the form or the details page of the created object. I would like to unit test whether the Model contains certain key/errorMessage combinations given some invalid dto. Did someone do similar stuff? Any pointers would be very much appreciated. Thanks. Best wishes, Christian

  • asp.net mvc script and style references

    - by tom
    I'm trying to include script and style references that will not break on deployment, however I can not even get the references to work locally. I have tried using Url.Content() and MVCContrib's <%=Html.ScriptInclude("")%>. My scripts are in a Scripts folder on the root of the site; my styles are in the usual Content/css/ folder. The scripts render like this: <script type="text/javascript" src="/Scripts/MicrosoftAjax.debug.js" ></script> This will not work in a view page in the Views folder. What am I doing wrong and what is the best way to handle this? I would have thought Url.Content() would at least work for styles but used in my master page, the link rendered <link href="/Content/css/Site.css rel="stylesheet" type="text/css" /> This does not work, because the Master Page is in a Shared folder, so what is really the way forward with this?

  • ASP.NET Compiles on page load, but not on Ctrl+Shift+B

    - by Steve Syfuhs
    during debug in cassini the code runs fine, but when I explictly build it, the compile breaks on an object saying it can't find the reference. During a breakpoint shows the proper reference to the object, and I can view the debug intellisense. The code itself is simple using CFTW.Controls; ... controls_LatestPresentations c = LoadControl("~/controls/LatestPresentations.ascx") as controls_LatestPresentations; c.loadContent(); return RenderControl(c); The control is a simple user control, with the namespace CFTW.Controls. The calling code is in a webcontrol, which lives in the same folder. I even tried adding the calling code to the same namespace.
