• Webreference vs servicereference. Why ony one works ?

  - by phenevo

  Hi, I've got two applications. One uses webreference to my webservice, and second use servicereference to my webservice. There is metohod which I'm invoking: [WebMethod] public Car[] GetCars(string carCode) { Cars[] cars= ModelToContract.ToCars(MyFacade.GetCars(carCode); return cars; } Car has two pools: string Code {get;set;} CarType Type {get;set;} public enum CarType { Van=0, Pickup=1 } I'm debuging this webMethod, and... at the end webservice throw good collection of cars, which has one car: code="bmw",Type.Van But... Application with webrefence receives the same collection and application with servicereference gets collection, where field code is null... Invoking servicereference: MyService myService=new MyService() Cars[] cars= client.GetCars(carcode); Invoking webservice: MyService.MyServiceSoapClient client = new MyServiceS.MyServiceSoapClient(); Cars[] cars= client.GetCars(carcode);

• ValueError with multi-table inheritance in Django Admin

  - by jorde

  I created two new classes which inherit model Entry: class Entry(models.Model): LANGUAGE_CHOICES = settings.LANGUAGES language = models.CharField(max_length=2, verbose_name=_('Comment language'), choices=LANGUAGE_CHOICES) user = models.ForeignKey(User) country = models.ForeignKey(Country, null=True, blank=True) created = models.DateTimeField(auto_now=True) class Comment(Entry): comment = models.CharField(max_length=2000, blank=True, verbose_name=_('Comment in English')) class Discount(Entry): discount = models.CharField(max_length=2000, blank=True, verbose_name=_('Comment in English')) coupon = models.CharField(max_length=2000, blank=True, verbose_name=_('Coupon code if needed')) After adding these new models to admin via admin.site.register I'm getting ValueError when trying to create a comment or a discount via admin. Adding entries works fine. Error msg: ValueError at /admin/reviews/discount/add/ Cannot assign "''": "Discount.discount" must be a "Discount" instance.

• UserControl Behaviour on a Windows Form

  - by AK

  Hi, I have a usercontrol UC1 with a combobox and a button. From the constructor, after initializing all the controls, I am populating the combobox with an array of information brought from other class library. I have kept the UC1 on windows form. When I tried to open the form's designer I see some errors and a suggestion to rebuild to fix the errors. After searching over net I found that the logic of populating the combobox is the culprit. I changed the code with an additional check of null and the issue is fixed now. My question is, how am i able to see the same usercontrol seperatly in designer view, but not when i placed the UC1 on a form and trying to see the designer view for the form? The same combobox populating logic should affect the drawing of UC1 when I try to see it in designer view right? Thanks, AK.

• Edit Html.ActionLink output string

  - by Aaron Salazar

  I'm trying to output the following HTML using Html.ActionLink: <a href="/About" class="read-more">Read More<span class="arrow">?</span></a> I'm getting it done by doing an ActionLink, which outputs an tag and then manipulating the string. <%= Html.ActionLink("[[replace]]", "Index", "About", null, new { @class = "read-more" }).ToHtmlString().Replace("[[replace]]", "Read More" + "<span class='arrow'>?</span>")%></p> It'd be good if I could put HTML directly into the ActionLink but there doesn't seem to be a way based on my internet searches. Sure, it works but it seems like a hack. Is there a better way to accomplish this?

• Custom view in ListView disappears while scrolling in Android

  - by troorl

  Hi. I wrote a simple custom view for rows in ListView. It works fine, but when I try to scroll the list, I see only white rows without content. And when scrolling is over, rows continue to show again. This is how I draw a custom view: @Override protected void onDraw(Canvas canvas) { if(poster != null) { canvas.drawBitmap(poster, padding, padding, paint); } canvas.drawText(title, 55 + padding, 16 + padding, paint); } Maybe I missed something? P.S. This is short screencast (400kb) http://dl.dropbox.com/u/190203/test.mpeg

• F# working with DataReader

  let getBytesData x = let len = reader.GetBytes(1, int64 0, null, 0, 0); // Create a buffer to hold the bytes, and then // read the bytes from the DataTableReader. let buffer : byte array = [||] reader.GetBytes(1, int64 0, buffer, 0, int32 len) |> ignore buffer let retVal = List [ while reader.Read() do yield (reader.GetString(0), getBytesData reader, reader.GetDateTime(2)) ] I have above code to read bytes[] from datareader. getBytesData function takes reader and returns bytes[] from reader. everything works fine but it getBytesData function is working very non-functional way. Is there any way i can optimize in F#? Sorry for kind of question, but i have started a new project on F# to squeeze all juice out of it, so trying to get each line most optimal way

• COM/DCOM problem when hosting executable is run as a service

  - by Mitch

  I am struggling for days now with the following problem: We have an executable that hosts a COM server, say x.exe. The COM object is instantiated as follows on the calling site: hRes = CoCreateInstance(CLSID_InterceptX, NULL, CLSCTX_SERVER, IID_IInterceptX, (void**)&pInterceptX); It all works fine when x runs as an regular application. We have a tool (I don't know how it works) that encapsulates x.exe so that it runs as a service under Windows (x.exe is a running process). In this case, we never receive a COM call in x.exe (validated by logging). Here is the weird part: From logging the calling site, I can tell that the COM object has been successfully instantiated and also the call to an interface function does not produce an error (SUCEEDED(hres) is true). Any ideas?

• SQL ConnectionString in global.asax overridden by web.config

  - by rlb.usa

  This is going to sound very odd, but I have a web.config like this: <connectionStrings> <remove name="LocalSqlServer"/> <add name="LocalSqlServer" connectionString="Data Source=BACKUPDB;..." providerName="System.Data.SqlClient"/> </connectionStrings> And a global.asax like this: void Session_Start(object sender, EventArgs e) { // Code that runs when a new session is started if (Application["con"] == null || Application["con"] == "") { Application["con"] = "Data Source=PRODUCTIONDB;..."; } } And EVERYWHERE in my code, I reference my ConnectionStrings like this: SqlConnection con = new SqlConnection(Convert.ToString(HttpContext.Current.Application["con"])); However, I see that everything I do inside this application goes to BACKUP db instead of PRODUCTIONDB. What is going on, how could this happen, and why? It doesn't make any sense to me, and it got me into a lot of trouble. We use LocalSqlServer string for FormsAuthentication.

• PreApplicationStartMethod Attribute causes exception

  - by Joop

  Strange thing happening to me with the PreApplicationStartMethod Attribute. I did implement it in my latest project. In the AssemblyInfo.cs I have the following line: [assembly: PreApplicationStartMethod(typeof(MyAssembly.Initializer), "Initialize")] The Type and method look like this: namespace MyAssembly { public static class Initializer { public static void Initialize() { TranslationKeys.Initialize(); } } } When I rebuild my application and load it in the browser I get the following error: The method specified by the PreApplicationStartMethodAttribute on assembly 'MyWebApp, Version=0.0.1.0, Culture=neutral, PublicKeyToken=null' cannot be resolved. Type: 'MyAssembly.Initializer', MethodName: 'Initialize'. Verify that the type is public and the method is public and static (Shared in Visual Basic). I really have no idea what the problem is.

• How to save http referer in rails

  - by TenJack

  I'm trying to save the site that a user came from when they sign up. Right now I have a before_filter in my ApplicationController: before_filter :save_referer def save_referer unless is_logged_in? session['referer'] = request.env["HTTP_REFERER"] unless session['referer'] end end Then when a user is created, it checks this session variable and sets it to nil. Sometimes this does not work and I'm worried there might be some unintended things happening with using session like this. Does anyone have a better way? Or some input perhaps? EDIT: This is the logic I am using to save the referer: def create @user = User.new(params[:user]) if @user.save_with(session[:referer]) .... end User def save_with(referer) self.referer = referer unless referer == "null" self.save end Is there any reason why this should not work?

  Once the added button in grid is clicked, how to find which row and column the button is located in the grid event handler, like click event or some other events? Not the button click event handler #region Grid event handler setup myGrid.MouseEnter += new MouseEventHandler(myGrid_MouseEnter); myGrid.MouseLeave += new MouseEventHandler(myGrid_MouseLeave); myGrid.MouseDown += new MouseButtonEventHandler(myGrid_MouseDown); myGrid.MouseUp += new MouseButtonEventHandler(myGrid_MouseUp); #endregion Thanks I notice that Boyan has some solution for the button click event handler case http://stackoverflow.com/questions/363100/in-wpf-how-can-i-determine-what-column-row-in-a-grid-a-control-is In the Click event handler for the button you say: int row; Button btn = sender as Button; if (btn != null) { row = Grid.GetRow(btn); // And you have the row number... } else { // A nasty error occurred... }

• Using key().id() on GAE Datastore and reverse geocoding

  - by Ivan Slaughter

  I have 6000 data of district, subdistrict. I need to represent this on dependent dropdown. The datamodel is for example; class Location(db.Model): location_name = db.StringProperty() location_parent = db.IntegerProperty() location_parent is reference to key() or id()? Still cannot decide which one is good. When i use key() as reference then using JSON to create jquery dependent drop down. My page loading/query and rendering time the dropdown is quite slow? Can i use key().id() as drop down option value to lighten up the page load? Any better solution for this parent/child reference for the drop down? For example: for the district record/entities the location-parent is null, for sub district record location_name will contain reference to parent district record. Other issue is to reverse geocoding the location to store or display geoPoint (lat,long)? Is google MAP API always find the exact lat,long of specific region boundaries or any error checking for the result?

• Problem retrieving Hostaddress from Win32_TCPIPPrinterPort

  - by Anthony

  I'm running into an odd issue retrieving printer port addresses. When I get all the entries in Win32_TCPIPPrinterPort, the HostAddress field (which should have the IP address) is usually blank/null, only the port name has a value. To make it a bit stranger, if a particular port is not in use by any printer, THEN the HostAddress will have the the proper value. The C# code is simple, and results in something like this; IP_192.168.1.100, printerportxyz, richTextBox1.Clear(); ManagementObjectSearcher portSearcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_TCPIPPrinterPort"); foreach (ManagementObject port in portSearcher.Get()) { richTextBox1.AppendText( String.Format("Name: {0} HostAddress: {1}", port["Name"], port["HostAddress"]) ); } I also tried the same thing in WSH/VBS, and saw the same behavior.

• .NET application per-machine/per-user licensing

  - by MainMa

  I am about to implement a very basic licensing feature for my application. A serial number may be granted per-machine (or per-operating-system) or per-user (as for CAL in Windows Server: if my application is used by several users on one machine or if it is used by one user on several machines). For per-operating-system licensing, I use SerialNumber of Win32_OperatingSystem. For per-user licensing, I use: WindowsIdentity currentIdentity = WindowsIdentity.GetCurrent(); if (currentIdentity != null) { SecurityIdentifier userSid = currentIdentity.User.AccountDomainSid; Console.WriteLine(userSid); } A hash of an obtained OS serial number or SID is then stored in the database, associated with application serial; each time the program starts, it queries the server, sending hash of OS SN/SID and application serial. Is it a right thing to do it or is it completely wrong? Will it work on every Windows machine? (For example, using motherboard serial is wrong)
