  • Do you use NDepend?

    - by Karsten
    Hi I've been trying out NDepend, been reading a few blogposts about it and even heard a podcast. I think that NDepend might be a really useful tool, but I still don't see where I would use it. How do you use it? Do you use it, why? why not? I would like to hear about some down to earth real world examples.

  • WCF push to client through firewall?

    - by Sire
    See also How does a WCF server inform a WCF client about changes? (Better solution then simple polling, e.g. Coment or long polling) I need to use push-technology with WCF through client firewalls. This must be a common problem, and I know for a fact it works in theory (see links below), but I have failed to get it working, and I haven't been able to find a code sample that demonstrates it. Requirements: WCF Clients connects to server through tcp port 80 (netTcpBinding). Server pushes back information at irregular intervals (1 min to several hours). Users should not have to configure their firewalls, server pushes must pass through firewalls that have all inbound ports closed. TCP duplex on the same connection is needed for this, a dual binding does not work since a port has to be opened on the client firewall. Clients sends heartbeats to server at regular intervals (perhaps every 15 mins) so server knows client is still alive. Server is IIS7 with WAS. The solution seems to be duplex netTcpBinding. Based on this information: WCF through firewalls and NATs Keeping connections open in IIS But I have yet to find a code sample that works.. I've tried combining the "Duplex" and "TcpActivation" samples from Microsoft's WCF Samples without any luck. Please can someone point me to example code that works, or build a small sample app. Thanks a lot!

  • DataGridView Selected Row Move UP and DOWN

    - by Silly Rabbit
    How can I allow selected rows in a DataGridView (DGV) to be moved up or down. I have done this before with a ListView. Unfortunetly, for me, replacing the DGV is not an option (curses). By the way, the DGV datasource is a Generic Collection. The DGV has two buttons on the side, yes, UP & Down. Can anyone help point me in the right direction. I do have the code that I used for the ListView if it'll help (it did not help me).

  • Problems trying to use Visual Studio 2010 and AJAX extensions

    - by Adrian
    Why can I not add ScriptManager control or UpdatePanel to a page in Visual Studio 2010? The drag( or double click) just fails - it seems like there is an incompatibility somewhere? UPDATE: This is 'default' install of 2010 Ultimate on Windows7, create a web application, cannot drag ScriptManager or UpdatePanel to the designer. Typing the declarations works. The cursor changes to the [+] icon when you drag it to the right place but nothing appears to happens on 'drop', briefly the documents name has * appended, this quickly changes back to normal, either is saves or does an undo. I'm assuming something is going wrong so it undos...but what is going wrong?

  • Problem with textbox inside updatepanel - not causing OnTextChanged event

    - by DaDa
    I have the following situation: I have a textbox inside an ajax updatepanel. Wherever the user types in the textbox I must display a message (different message that depends on the user typed data). <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always"> <ContentTemplate> <asp:TextBox ID="txtMyTexbox" runat="server" Width="500px" OnTextChanged="txtMyTexbox_TextChanged" AutoPostBack="true"></asp:TextBox> <br /> <asp:Label ID="lblMessage" runat="server" CssClass="errorMessage" Visible="false">Hello World</asp:Label> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="txtMyTexbox" /> </Triggers> </asp:UpdatePanel> In server side I have written the following at page load ScriptManager.GetCurrent(this).RegisterAsyncPostBackControl(txtMyTexbox); and the method like this protected void txtMyTexbox_TextChanged(object sender, EventArgs e) { if (.....) { lblMessage.Visible = false; } else { lblMessage.Visible = true; } } My problem now is that: when the user types in the textbox it doesn't cause OnTextChanged event. Am I missing something?

  • Telerik Object reference not set to an instance of an object

    - by Duncan
    Hi, I have a main form which contains multiple worker threads. These threads raise events which update Telerik controls on the main form. The event handlers contain code which check if InvokeRequired and BeginInvoke where required. At random interval I am receiving the following exception, and have no idea on how where to find this?

  • Where to use Controller.HttpContext

    - by Ben
    Hi, In my base controller's constructor I am calling an extension method that checks for specific cookies on the client. Currently I am using System.Web.HttpContext.Current to get the current context. However, I am lead to believe that I should be using Controller.HttpContext since it is more testable and contains additional information about the request. However, Controller.HttpContext returns null on creation (believe this is by design) but also on Initialize and Execute methods (unless I use Routing.RequestContext.HttpContext?). So if I should be using Controller.HttpContext instead of HttpContext.Current, at what point is it available to me in a request? Thanks Ben

  • Jquery-UI tabs : Double loading of the default tab

    - by Stephane
    I use jqueryui-tabs to display a tabbed UI. here is how my markup looks in a MasterPage: <div id="channel-tabs" class="ui-tabs"> <ul class="ui-tabs-nav"> <li><%=Html.ActionLink("Blogs", "Index", "Blog", new { query = Model.Query, lang = Model.SelectedLanguage, fromTo = Model.FromTo, filters = Model.FilterId }, new{ title="Blog Results" }) %></li> <li><%=Html.ActionLink("Forums", "Index", "Forums", new { query = Model.Query, lang = Model.SelectedLanguage, fromTo = Model.FromTo, filters = Model.FilterId }, null) %></li> <li><%=Html.ActionLink("Twitter", "Index", "Twitter", new { query = Model.Query, lang = Model.SelectedLanguage, fromTo = Model.FromTo, filters = Model.FilterId }, null) %></li> </ul> <div id="Blog_Results"> <asp:ContentPlaceHolder ID="ResultPlaceHolder" runat="server"> </asp:ContentPlaceHolder> </div> If the content is loaded via ajax, I return a partial view with the content of the tab. If the content is loaded directly, I load a page that include the content in the ContentPlaceHolder. somewhat like this : <asp:Content ID="Content2" ContentPlaceHolderID="BlogPlaceHolder" runat="server"> <%=Html.Partial("Partial",Model) %> </asp:Content> //same goes for the other tabs. With this in place, if I access the url "/Forums" It loads the forum content in the Blog tab first, trigger the ajax load of the Blog tab and replace the content with the blog content. I tried putting a different placeholder for each tab, but that didn't fix everything either, since when loading "/Forums" it will sure load the forum tab, but the Blog tab will show up first. Furthermore, when using separate placeholders, If I load the "/Blogs" url, It will first load the content statically in the Blog contentplaceholder and then trigger an ajax call to load it a second time and replace it. If I just link the tab to the hashtag, then when loading the forum tabs, I won't get the blog content... How would you achieve the expected behaviour? I feel like I might have a deeper probelm in the organization of my views. Is putting the tabs in the masterpage the way to go? Maybe I should just hijax the links manually and not rely on jquery-ui tabs to do the work for me. I cannot load all tabs by default and display them using the hash tags, I need an ajax loading because it is a search process that can be long. So to sum up : /Forum should load the forum tab, and let the other tabs be loaded with an ajax call when clicking on it. /Twitter should load the twitter tab and let the other tabs.... the same goes for /Blogs and any tabs I would add later. Any idea to have this working properly?

  • C# - Screenshot of process under Windows Service

    - by Jonathan.Peppers
    We have to run a process from a windows service and get a screenshot from it. We tried the BitBlt and PrintWindow Win32 calls, but both give blank (black) bitmaps. If we run our code from a normal user process, it works just fine. Is this something that is even possible? Or could there be another method to try? Things we tried: Windows service running as Local System, runs process as Local System - screenshot fails Windows service running as Administrator, runs process as Administrator - screenshot fails. Windows application running as user XYZ, runs a process as XYZ - screenshot works with both BitBlt or PrintWindow. Tried checking "Allow service to interact with desktop" from Local System We also noticed that PrintWindow works better for our case, it works if the window is behind another window. For other requirements, both the parent and child processes must be under the same user. We can't really use impersonation from one process to another.

  • Cannot use WCF service from windows mobile 5: no endpoint found.

    - by sweeney
    Hi All, I'm trying to figure out how to call a WCF service from a windows smart phone. I have a very simple smartphone console app, which does nothing but launch and make 1 call to the service. The service simply returns a string. I am able to instantiate the proxy class but when i call the method it throws an exception: There was no endpoint listening at http://mypcname/Service1.svc/basic that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. The inner exception: Could not establish connection to network. I've tried to follow this tutorial on setting up services with windows mobile. I've used the NetCFSvcUtil to create the proxy classes. I have the service running on IIS on my machine and had the Util consume the wsdl from that location. I've created a basic http binding as suggested in the article and i think i've pointed the proxy at the correct uri. Here some sections of relevant code in case it's helpful to see. If anyone has any suggestions, i'd really appreciate it. I'm not sure what else i can poke at to get this thing to work. Thanks! Client, (Program.cs): using System; using System.Linq; using System.Collections.Generic; using System.Text; namespace WcfPoC { class Program { static void Main(string[] args) { try { Service1Client proxy = new Service1Client(); string test = proxy.GetData(5); } catch (Exception e) { Console.WriteLine(e.Message); Console.WriteLine(e.InnerException.Message); Console.WriteLine(e.StackTrace); } } } } Client Proxy excerpt (Service1.cs): [System.Diagnostics.DebuggerStepThroughAttribute()] [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")] public partial class Service1Client : Microsoft.Tools.ServiceModel.CFClientBase<IService1>, IService1 { //modified according to the walk thru linked above... public static System.ServiceModel.EndpointAddress EndpointAddress = new System.ServiceModel.EndpointAddress("http://boston7/Service1.svc/basic"); /* *a bunch of code create by the svc util - left unmodified */ } The Service (Service1.svc.cs): using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.Text; namespace WcfService1 { // NOTE: If you change the class name "Service1" here, you must also update the reference to "Service1" in Web.config and in the associated .svc file. public class Service1 : IService1 { public string GetData(int value) //i'm calling this one... { return string.Format("You entered: {0}", value); } public CompositeType GetDataUsingDataContract(CompositeType composite) { if (composite.BoolValue) { composite.StringValue += "Suffix"; } return composite; } } } Service Interface (IService1.cs): using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.Text; namespace WcfService1 { // NOTE: If you change the interface name "IService1" here, you must also update the reference to "IService1" in Web.config.

  • Create an ASMX web service from a WSDL file

    - by metanaito
    I have a WSDL file and I am trying to create a web service that conforms to the WSDL. I've created clients using WSDL files that consume an existing service, but I've never created a web service that needed to follow a specific WSDL. I've gone as far as using: wsdl.exe mywsdl.wsdl /l:VB /serverInterface Now I've got a .vb file generated from that WSDL. However I am not sure what I'm supposed to do with this VB file. It looks like it's got a public interface in there but no class that implements the interface. It also has a bunch of partial classes for the types in the WSDL. I was expecting there to be some sort of stub where I put in the code to complete the service calls. I've only created simple web services before and none of them used public interfaces so I'm unfamiliar with what is going on here. At this point I'm not sure how I use the generated .vb file and make it work with an .asmx file and what additional coding is needed to complete the interface.

  • Bidirectional Serialization with Linq

    - by Andy
    Anyone know why only undirectional serialization is supported in the Linq designer? Consider the following example: Say we have a Customer who requested an Order containing Products. We set the Serialization Mode in the Linq designer to Unidirectional to enable serialization. When looking at the code for the Order object, the DataMember attribute is added to all its internal properties such as ID,OrderNumber, etc. and also to the EntitySet of Products, but not to Customer. One can get around this by manually adding the DataMember attribute to Customer, but this becomes quite cumbersome when there's loads of entities in the database.

  • LINQ to Entity, using a SQL LIKE operator

    - by Mario
    I have a LINQ to ENTITY query that pulls from a table, but I need to be able to create a "fuzzy" type search. So I need to add a where clause that searches by lastname IF they add the criteria in the search box (Textbox, CAN be blank --- in which case it pulls EVERYTHING). Here is what I have so far: var query = from mem in context.Member orderby mem.LastName, mem.FirstName select new { FirstName = mem.FirstName, LastName = mem.LastName, }; That will pull everything out of the Member table that is in the Entity object. Then I have an addition to the logic: sLastName = formCollection["FuzzyLastName"].ToString(); if (!String.IsNullOrEmpty(sLastName)) query = query.Where(ln => ln.LastName.Contains(sLastName)); The problem is when the search button is pressed, nothing is returned (0 results). I have run the query against the SQL Server that I expect to happen here and it returns 6 results. This is the query I expect: SELECT mem.LastName, mem.FirstName FROM Members mem WHERE mem.LastName = 'xxx' (when xxx is entered into the textbox) Anyone see anything wrong with this?

  • Hidden Field losing its Value on postback

  • Draw Bitmap with alpha channel

    - by Paja
    I have a Format32bppArgb backbuffer, where I draw some lines: var g = Graphics.FromImage(bitmap); g.Clear(Color.FromArgb(0)); var rnd = new Random(); for (int i = 0; i < 5000; i++) { int x1 = rnd.Next(ClientRectangle.Left, ClientRectangle.Right); int y1 = rnd.Next(ClientRectangle.Top, ClientRectangle.Bottom); int x2 = rnd.Next(ClientRectangle.Left, ClientRectangle.Right); int y2 = rnd.Next(ClientRectangle.Top, ClientRectangle.Bottom); Color color = Color.FromArgb(rnd.Next(0, 255), rnd.Next(0, 255), rnd.Next(0, 255)); g.DrawLine(new Pen(color), x1, y1, x2, y2); } Now I want to copy bitmap in Paint event. I do it like this: void Form1Paint(object sender, PaintEventArgs e) { e.Graphics.DrawImageUnscaled(bitmap, 0, 0); } Hovewer, the DrawImageUnscaled copies pixels and applies the alpha channel, thus pixels with alpha == 0 won't have any effect. But I need raw byte copy, so pixels with alpha == 0 are also copied. So the result of these operations should be that e.Graphics contains exact byte-copy of the bitmap. How to do that? Summary: When drawing a bitmap, I don't want to apply the alpha channel, I merely want to copy the pixels.

  • refresh user control inside multiview

    - by daisy
    In my parentpage I have dropdownlist, multiview and button. Multiview has a user control. On click of the button i pass the selected value from dropdown to the user control and call the databind method to populate the user control with corresponding data. User control has gridview which is populated using objectDataSource. I'm using the ObjectCreating (ObjectDataSource) to set the objectInstance. 1st time everything works fine. But when the dropdown selection is changed and the button is clicked again then the user control does not refresh. What do I need to do so that the user control refreshed each time the drop down selection is changed. All the help is appreciated Thanks

  • C# Sockets Buffer Overflow No Error

    - by Michael Covelli
    I have one thread that is receiving data over a socket like this: while (sock.Connected) { // Receive Data (Block if no data) recvn = sock.Receive(recvb, 0, rlen, SocketFlags.None, out serr); if (recvn <= 0 || sock == null || !sock.Connected) { OnError("Error In Receive, recvn <= 0 || sock == null || !sock.Connected"); return; } else if (serr != SocketError.Success) { OnError("Error In Receive, serr = " + serr); return; } // Copy Data Into Tokenizer tknz.Read(recvb, recvn); // Parse Data while (tknz.MoveToNext()) { try { ParseMessageAndRaiseEvents(tknz.Buffer(), tknz.Length); } catch (System.Exception ex) { string BadMessage = ByteArrayToStringClean(tknz.Buffer(), tknz.Length); string msg = string.Format("Exception in MDWrapper Parsing Message, Ex = {0}, Msg = {1}", ex.Message, BadMessage); OnError(msg); } } } And I kept seeing occasional errors in my parsing function indicating that the message wasn't valid. At first, I thought that my tokenizer class was broken. But after logging all the incoming bytes to the tokenizer, it turns out that the raw bytes in recvb weren't a valid message. I didn't think that corrupted data like this was possible with a tcp data stream. I figured it had to be some type of buffer overflow so I set sock.ReceiveBufferSize = 1024 * 1024 * 8; and the parsing error never, ever occurs in testing (it happens often enough to replicate if I don't change the ReceiveBufferSize). But my question is: why wasn't I seeing an exception or an error state or something if the socket's internal buffer was overflowing before I changed this buffer size?
