  • Add ASP.NET web service while impersonating credentials.

    - by George
    I have a web reference that I do not have access to through my windows credentials, but do through impersonation. Unfortunately, I cannot update or add the reference because of my lack of credentials. When the service is added, it works fine when I set impersonation to true and add credentials. Is there a way to impersonate a credentials when adding/updating a web service reference through the GUI?

  • ASP.Net GridView UpdatePanel Paging Gives Error On Second Click

    - by joe
    I'm trying to implement a GridView with paging inside a UpdatePanel. Everything works great when I do my first click. The paging kicks in and the next set of data is loaded quickly. However, when I then try to click a link for another page of data, I get the following error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12030 aspx code <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <contenttemplate> <asp:GridView ID="GridView1" runat="server" CellPadding="2" AllowPaging="true" AllowSorting="true" PageSize="20" OnPageIndexChanging="GridView1_PageIndexChanging" OnSorting="GridView1_PageSorting" AutoGenerateColumns="False"> <Columns> <asp:BoundField DataField="ActivityLogID" HeaderText="Activity Log ID" SortExpression="ActivityLogID" /> <asp:BoundField DataField="ActivityDate" HeaderText="Activity Date" SortExpression="ActivityDate" /> <asp:BoundField DataField="ntUserID" HeaderText="NTUserID" SortExpression="ntUserID" /> <asp:BoundField DataField="ActivityStatus" HeaderText="Activity Status" SortExpression="ActivityStatus" /> </Columns> </asp:GridView> </contenttemplate> </asp:UpdatePanel> code behind private void bindGridView(string sortExp, string sortDir) { SqlCommand mySqlCommand = new SqlCommand(sSQL, mySQLconnection); SqlDataAdapter mySqlAdapter = new SqlDataAdapter(mySqlCommand); mySqlAdapter.Fill(dtDataTable); DataView myDataView = new DataView(); myDataView = dt.DefaultView; if (sortExp != string.Empty) { myDataView.Sort = string.Format("{0} {1}", sortExp, sortDir); } GridView1.DataSource = myDataView; GridView1.DataBind(); if (mySQLconnection.State == ConnectionState.Open) { mySQLconnection.Close(); } } protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) { GridView1.PageIndex = e.NewPageIndex; bindGridView(); } protected void GridView1_PageSorting(object sender, GridViewSortEventArgs e) { bindGridView(e.SortExpression, sortOrder); } any clues on what is causing the error on the second click?

  • ASP.Net MVC Object Reference in Edit View when using DropDownListFor()

    - by hermiod
    This question is related to another I ask recently, it can be found here for some background information. Here is the code in the Edit ActionResult: public virtual ActionResult Edit(int id) { ///Set data for DropDownLists. ViewData["MethodList"] = tr.ListMethods(); ViewData["GenderList"] = tr.ListGenders(); ViewData["FocusAreaList"] = tr.ListFocusAreas(); ViewData["SiteList"] = tr.ListSites(); ViewData["TypeList"] = tr.ListTalkbackTypes(); ViewData["CategoryList"] = tr.ListCategories(); return View(tr.GetTalkback(id)); } I add lists to the ViewData to use in the dropdownlists, these are all IEnumerable and are all returning values. GetTalkback() returns an Entity framework object of type Talkback which is generated from the Talkback table. The DropDownListFor code is: <%: Html.DropDownListFor(model=>model.method_id,new SelectList(ViewData["MethodList"] as IEnumerable<SelectListItem>,"Value","Text",Model.method_id)) %> The record I am viewing has values in all fields. When I click submit on the View, I get an Object reference not set to an instance of an object. error on the above line. There are a number of standard fields in the form prior to this, so the error is only occurring on dropdown lists, and it is occurring on all of them. Any ideas? This is my first foray in to MVC, C#, and Entity so I am completely lost!

  • N-Tier Architecture - Structure with multiple projects in VB.NET

    - by focus.nz
    I would like some advice on the best approach to use in the following situation... I will have a Windows Application and a Web Application (presentation layers), these will both access a common business layer. The business layer will look at a configuration file to find the name of the dll (data layer) which it will create a reference to at runtime (is this the best approach?). The reason for creating the reference at runtime to the data access layer is because the application will interface with a different 3rd party accounting system depending on what the client is using. So I would have a separate data access layer to support each accounting system. These could be separate setup projects, each client would use one or the other, they wouldn't need to switch between the two. Projects: MyCompany.Common.dll - Contains interfaces, all other projects have a reference to this one. MyCompany.Windows.dll - Windows Forms Project, references MyCompany.Business.dll MyCompany.Web.dll - Website project, references MyCompany.Business.dll MyCompany.Busniess.dll - Business Layer, references MyCompany.Data.* (at runtime) MyCompany.Data.AccountingSys1.dll - Data layer for accounting system 1 MyCompany.Data.AccountingSys2.dll - Data layer for accounting system 2 The project MyCompany.Common.dll would contain all the interfaces, each other project would have a reference to this one. Public Interface ICompany ReadOnly Property Id() as Integer Property Name() as String Sub Save() End Interface Public Interface ICompanyFactory Function CreateCompany() as ICompany End Interface The project MyCompany.Data.AccountingSys1.dll and MyCompany.Data.AccountingSys2.dll would contain the classes like the following: Public Class Company Implements ICompany Protected _id As Integer Protected _name As String Public ReadOnly Property Id As Integer Implements MyCompany.Common.ICompany.Id Get Return _id End Get End Property Public Property Name As String Implements MyCompany.Common.ICompany.Name Get Return _name End Get Set(ByVal value as String) _name = value End Set End Property Public Sub Save() Implements MyCompany.Common.ICompany.Save Throw New NotImplementedException() End Sub End Class Public Class CompanyFactory Implements ICompanyFactory Public Function CreateCompany() As ICompany Implements MyCompany.Common.ICompanyFactory.CreateCompany Return New Company() End Function End Class The project MyCompany.Business.dll would provide the business rules and retrieve data form the data layer: Public Class Companies Public Shared Function CreateCompany() As ICompany Dim factory as New MyCompany.Data.CompanyFactory Return factory.CreateCompany() End Function End Class Any opinions/suggestions would be greatly appreciated.

  • Configuring Cruise Control Net with sourcesafe - Unable to load array item 'executable'

    - by albert
    Hi all, I'm trying to create a continuous integration environment. To do so, I've used a guide that can be found at http://www.15seconds.com/issue/040621.htm. In this step by step, the goal is to create a CI with CCNet, NAnt, NUni, NDoc, FxCop and source safe. I've been able to create my build by using the command prompt (despite the the different versions issues). The problem has come with the configuration of ccnet.config I've made some changes because of the new versions, but I'm still getting errors when starting the CCNet server. Can anyone help me to fix this issue or point where to find a guide with this scenario? The error that I'm getting: Unable to instantiate CruiseControl projects from configuration document. Configuration document is likely missing Xml nodes required for properly populating CruiseControl configuration. Unable to load array item 'executable' - Cannot convert from type System.String to ThoughtWorks.CruiseControl.Core.ITask for object with value: "\DevTools\nant\bin\NAnt.exe" Xml: E:\DevTools\nant\bin\NAnt.exe My CCNet config file below: <cruisecontrol> <project name="BuildingSolution"> <webURL>http://localhost/ccnet</webURL> <modificationDelaySeconds>10</modificationDelaySeconds> <triggers> <intervaltrigger name="continuous" seconds="60" /> </triggers> <sourcecontrol type="vss" autoGetSource="true"> <ssdir>E:\VSS\</ssdir> <executable>C:\Program Files\Microsoft Visual SourceSafe\SS.EXE</executable> <project>$/CCNet/slnCCNet.root/slnCCNet</project> <username>Albert</username> <password></password> </sourcecontrol> <prebuild type="nant"> <executable>E:\DevTools\nant\bin\NAnt.exe</executable> <buildFile>E:\Builds\buildingsolution\WebForm.build</buildFile> <logger>NAnt.Core.XmlLogger</logger> <buildTimeoutSeconds>300</buildTimeoutSeconds> </prebuild> <tasks> <nant> <executable>E:\DevTools\nant\bin\nant.exe</executable> <nologo>true</nologo> <buildFile>E:\Builds\buildingsolution\WebForm.build</buildFile> <logger>NAnt.Core.XmlLogger</logger> <targetList> <target>build</target> </targetList> <buildTimeoutSeconds>6000</buildTimeoutSeconds> </nant> </tasks> <publishers> <merge> <files> <file>E:\Builds\buildingsolution\latest\*-results.xml</file> </files> </merge> <xmllogger /> </publishers> </project> </cruisecontrol> enter code here

  • Append XML string block WITH NAMESPACE REF to existing XmlDocument in .NET

    - by FT
    I have an xml document (XmlDocument) which looks like this... <stuff xmlns:n="hhtp://tempuri.com/"> </stuff> ... and a "fragment" (string) which looks like this <things> <thing n:type="info"> </thing> </things> I want to "inject" the fragment into the main document. How? (HINT: You can't use XmlDocumentFragment because the namespace 'n' isn't declared in the fragment, and the object model complains about this - throwing an 'unknown namespace' error even though the resultant document will be perfectly valid.)

  • Why don't the .net 4.0 charting controls work in Visual Web Developer 2010 Express?

    - by kc
    The .net charting controls are now built into .net 4.0. They work great in Visual Studio 2010. However, they do not work in Visual Web Developer 2010 Express (which is what I have at home.) I get the error, System.Web.HttpException: Error executing child request for ChartImg.axd. That sounds like the message from .net 3.5 if charting wasn't set up correctly. But the bottom of the same page says, "Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1" Does anyone know why this doesn't work?

  • How to reuse socket in .NET?

    - by Hermann
    I am trying to reconnect to a socket that I have disconnected from but it won't allow it for some reason even though I called the Disconnect method with the argument "reuseSocket" set to true. _socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); _socket.Connect(ipAddress, port); //...receive data _socket.Disconnect(true); //reuseSocket = true //...wait _socket.Connect(ipAddress, port); //throws an InvalidOperationException: Once the socket has been disconnected, you can only reconnect again asynchronously, and only to a different EndPoint. BeginConnect must be called on a thread that won't exit until the operation has been completed. What am I doing wrong?

  • Setting System.Drawing.Color through .NET COM Interop

    - by Maxim
    I am trying to use Aspose.Words library through COM Interop. There is one critical problem: I cannot set color. It is supposed to work by assigning to DocumentBuilder.Font.Color, but when I try to do it I get OLE error 0x80131509. My problem is pretty much like this one: http://bit.ly/cuvWfc update: Code Sample: from win32com.client import Dispatch Doc = Dispatch("Aspose.Words.Document") Builder = Dispatch("Aspose.Words.DocumentBuilder") Builder.Document = Doc print Builder.Font.Size print Builder.Font.Color Result: 12.0 Traceback (most recent call last): File "aaa.py", line 6, in <module> print Builder.Font.Color File "D:\Python26\lib\site-packages\win32com\client\dynamic.py", line 501, in __getattr__ ret = self._oleobj_.Invoke(retEntry.dispid,0,invoke_type,1) pywintypes.com_error: (-2146233079, 'OLE error 0x80131509', None, None) Using something like Font.Color = 0xff0000 fails with same error message While this code works ok: using Aspose.Words; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Document doc = new Document(); DocumentBuilder builder = new DocumentBuilder(doc); builder.Font.Color = System.Drawing.Color.Blue; builder.Write("aaa"); doc.Save("c:\\1.doc"); } } } So it looks like COM Interop problem.

  • .net code readability and maintainability

    - by george9170
    There Currently is a local debate as to which code is more readability We have one programmer who comes from a c background and when that programmer codes it looks like string foo = "bar"; if (foo[foo.Length - 1] == 'r') { } We have another programmer that doesn't like this methodology and would rather use if (foo.EndsWith("r")) { } which way of doing these types of operations is better?

  • ASP .NET MVC partial views and routing

    - by Johnny
    Hi, I have an MVC view that contains a number of partial views. These partial views are populated using partial requests so the controller for the view itself doesn't pass any data to them. Is it possible to reload the data in one of those partial views if an action was triggered in another? For example, one partial view has a jqGrid and I want to refresh the data in another partial view when a user selects a new row in this grid. Is there a code example for this scenario (in C#) that I can look at to see what am I doing wrong? I am using ajax calls to trigger a new request but non of the partial views are refreshed so I am not sure if the issue is with the routing, the controller, or if this even possible at all! Thanks!

  • Question about XML deserialization in .net

    - by ryudice
    Hi, I'm trying to deserialize an XML that comes from a web service but I do not know how to tell the serializer how to handlke this piece of xml: <Movimientos> <Movimientos> <NOM_ASOC>pI22E7P30KWB9KeUnI+JlMRBr7biS0JOJKo1JLJCy2ucI7n3MTFWkY5DhHyoPrWs</NOM_ASOC> <FEC1>RZq60KwjWAYPG269X4r9lRZrjbQo8eRqIOmE8qa5p/0=</FEC1> <IDENT_CLIE>IYbofEiD+wOCJ+ujYTUxgsWJTnGfVU+jcQyhzgQralM=</IDENT_CLIE> </Movimientos> <Movimientos> As you can see, the child tag uses the same tag as its parent, I suppose this is wrong however the webservice is provided by an external company and that wont change it, is there any way or any library to tidy up XML or how can I use an attribute on my class so that the serializer gets it right? thanks for any help.

    Is there an easy way to present time (hh:mm) as a decimal value? Example, 01:08 should become 1,13. I have an asp:textbox masked (ajax) as time with the mask format "99:99". Next to this box I need to present the entered value as decimal. <asp:TextBox ID="time" runat="server" /> hh:mm ([time in decimal format]) <ajaxToolkit:MaskedEditExtender runat="server" Mask="99:99" TargetControlID="time" MaskType="Time" />

  • Problem retrieving multiple instances of the same asp.net session variable

    - by sw1sh
    I'm having problems with retrieving multiple instances of a session variable from an InProc session state. In the following code I persist a simple BusinessObject into a session variable on the Page_Load event. On the click of a button I try to retrieve the object back into 2 new declared instances of the same BusinessObject. All works great until I change one of the properties in the first instance, it changes the second instance as well. Is this normal behaviour? I would have thought as these were new instances they wouldn’t demonstrate static behaviour? Any ideas where I'm going wrong? Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Page.IsPostBack Then ' create a new instance of a business object and set a containg variable Dim BO As New BusinessObject BO.SomeVariable = "test" ' persist to inproc session Session("BO") = BO End If End Sub Protected Sub btnRetrieveSessionVariable_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnRetrieveSessionVariable.Click ' retrieve the session variable to a new instance of BusinessObject Dim BO1 As New BusinessObject If Not Session("BO") Is Nothing Then BO1 = Session("BO") ' retrieve the session variable to a new instance of BusinessObject Dim BO2 As New BusinessObject If Not Session("BO") Is Nothing Then BO2 = Session("BO") ' change the property value on the first instance BO1.SomeVariable = "test2" ' why has this changed on both instances? Dim strBO1Property As String = BO1.SomeVariable Dim strBO2Property As String = BO2.SomeVariable End Sub ' simple BusinessObject class Public Class BusinessObject Private _SomeVariable As String Public Property SomeVariable() As String Get Return _SomeVariable End Get Set(ByVal value As String) _SomeVariable = value End Set End Property End Class

  • help with jquery ajax and templates in asp.net mvc

    - by NachoF
    So I have a complex form for an IncomeDeclaration. Its going to display a textfield GrossIncome for each Activity that the IncomeDeclaration is related to... this all gets done on the server and works just fine.... the problem is. The User should also be able to add Activities on the fly.. through javascript... so when the user clicks on Add Activity a Dropdown and a textfield must be appended to the bottom the activities list... heres what Ive got so far <tbody id="activities"> @Html.EditorFor(model => model.income.EconomicActivityIncomeDeclarations) </tbody> </table> <a href="#" id="add_activity">Agregar Otra Actividad</a> </fieldset> <script type="text/javascript"> $("#add_activity").click(function () { $.getJSON('/IncomeDeclarations/GetEconomicActivities', function (data) { var select = new Select(); var data = new Array(); for (var i = 0; i < data.length; i++) { var option = new Option(data[i]["name"], data[i]["i"]) //should do something here } //should call the template and append to #activities }); }); </script> <script id="template" type="text/x-jquery-tmpl"> <tr> <td><select name="income.EconomicActivityIncomeDeclarations[${SomeNumber}].EconomicActivityId"> ${MyOptions} </select></td> <td><input type="text" name="income.EconomicActivityIncomeDeclarations[${SomeNumber}].GrossIncome" /></td>> </tr> </script> } The name attribute for both the select and the text_field is key for this to work... otherwise modelbinding wont work... I would think that if the SomeNumber variable is set to new Date.GetTime() model Binding should work just fine... I actually dont see the need of ajax for this but thats another topic.. I just havent figured out a way to do this without ajax... right now I want to get the template to work and append the form elements to the bottom of the list.
