  • Error window show modal in MVVM WPF

    - by bluebit
    Hi guys I have implemented my MVVM error message as a message dialog that subscribes to error messages via a mediator class, so that other viewmodels can notify it if any errors occur. When an error occurs, I set the visibility attribute in the viewmodel to Visible, to display the error window. This is all bound in the Error window from the viewmodel. However, this window is NOT modal! I need to show it as a dialog and not just set the visibility to true - is there any kind of binding I can do, even if I have to extend the functionality of the window? I'd rather not break MVVM if I can avoid it. Thanks!

  • How to escape forward slash?

    - by AndrewB
    I have the following sql command through code and because the parameter contains a forward slash when I evaluate the sql row after the update the column is just empty. sqlCommand.CommandText = String.Format("update {0} set {1}='{2}'where id = @Id", tableName, ColumnName, forwardSlashText); sqlCommand.Parameters.Add("@Id", SqlDbType.UniqueIdentifier).Value = rowId; numRowsAffected = sqlCommand.ExecuteNonQuery(); adding a log.debug to this command i get the following output... update my_table_name set mime_type='application/pdf' where id = @Id So i would assume that the command is correct, but then looking at the row the mime_type column is empty.

  • UIScrollview doesnt resize in NavigationController when rotated

    - by Icky
    Hey, I have been dealing with this issue for 2 days now, not able to find a solution. I have a navigationcontroller as a root view controller. This one pushes a UIViewcontroller which in turn has a UIScrollview I created with IB. Additionally there is the Navigation bar. My problem arises, when I rotate the IPhone to Landscape mode. In -(void) didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation I want my scrollview to take up the full width (480 px) which it doesnt. I am able to set the frame of the navigation bar to full width perfectly fine, but not the scrollview. I have read that this might be because of the autoresizing masks set in the rooviewcontroller but I have tried out a couple of solutions - none worked for me. Any ideas on how to challenge the problem? Dont know where to start looking.

  • Does UIGestureRecognizer work on a UIWebView?

    - by rscott
    I am attempting to get a UIGestureRecognizer working with a UIWebview which is a subview of a UIScrollView. This sounds odd but when I have the numberOfTouchesRequired set to 2 the selector fires, but when numberOfTouchesRequired is set to one the selector doesn't fire. Here is my code: UITapGestureRecognizer *tap1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(select1:)]; tap1.numberOfTouchesRequired = 2; tap1.numberOfTapsRequired = 1; tap1.delegate = self; [self.ans1WebView addGestureRecognizer:tap1]; [tap1 release]; - (void) select1:(UILongPressGestureRecognizer *)sender { //Do Stuff } I've confirmed this by using the Apple sample for UIGestureRecognizer and inserting a webview in their nib. Their tap code works everywhere but inside the area of the webview.

  • WPF TreeView drag and drop using preview

    - by imekon
    I'm handling drag and drop events in a TreeView using PreviewMouseDown, PreviewMouseMove and PreviewMouseUp, however, there is an issue. In my PreviewMouseDown handler, I set everything ready in case there's a drag started (detected in the Move event), however I set e.Handled = true. This means that standard selection events don't get generated on my tree! What I want to be able to do in my Up event is to invoke the standard treeview selection changed event - except I cannot call events outside of the tree. So what's the correct way to do this? I have tried using the standard MouseDown, MouseMove and MouseUp events however there's an issue with messing up my multiple selection feature that means I need to use the Preview version of those events.

  • Single Sign On with Forms Authentication

    - by Christo Fur
    I am trying to set up Single sign on for 2 websites that reside on the same domain e.g. http://mydomain (top level site that contains a forms-auth login page) http://mydomain/admin (seperately developed website residing in a Virtual Application within the parent website) Have read a few articles on Single Sign on e.g. http://www.codeproject.com/KB/aspnet/SingleSignon.aspx And they seem to suggest it is just a case of having the same machinekey section in each web.config so that the cookie encryprion and decryption is the same for each application I have set this up and I never get prompted for credentials in the sub-website (the virtual application) I always get prompted in the parent site. In addition to having the same machinekey I've also tried adding the same <authentication> and <authorisation> elements Any idea what I could be missing?

  • C# winforms Picturebox, backgroundimage zoomed at the top?

    - by Oskar Kjellin
    I have a picturebox where I set change the BackgroundImage frequently. I have a the BackgroundImageLayout set to Zoom. The problem is that when an image does not have the same scale as the picturebox, the picture is drawn in the middle. That is, the top and the bottom padding of the picturebox is always the same. I would like for the BackgroundImage to always be aligned at the top. What is the easiest and most performance efficient way of doing this? I can add that I download the images from the internet. If you think that the best way to deal with this is to resize them at that point I can do that :)

  • WPF drop shadow

    - by Petezah
    Currently I'm making something in WPF that has a border that contains a grid and other controls. The problem I'm facing is that whenever I set the Border.Effect property to a drop shadow effect every control contained in the border now has a drop shadow. Is there a way to set the shadow just to the border and not every control contained in the border? Here is a short example of my code: <Grid> <Border Margin="68,67,60,67" BorderBrush="Black" BorderThickness="1" CornerRadius="10"> <Border.Effect> <DropShadowEffect/> </Border.Effect> <Rectangle Fill="White" Stroke="Black" Margin="37,89,118,98" /> </Border> </Grid>

  • Why aren't we programming on the GPU???

    - by Chris
    So I finally took the time to learn CUDA and get it installed and configured on my computer and I have to say, I'm quite impressed! Here's how it does rendering the Mandelbrot set at 1280 x 678 pixels on my home PC with a Q6600 and a GeForce 8800GTS (max of 1000 iterations): Maxing out all 4 CPU cores with OpenMP: 2.23 fps Running the same algorithm on my GPU: 104.7 fps And here's how fast I got it to render the whole set at 8192 x 8192 with a max of 1000 iterations: Serial implemetation on my home PC: 81.2 seconds All 4 CPU cores on my home PC (OpenMP): 24.5 seconds 32 processors on my school's super computer (MPI with master-worker): 1.92 seconds My home GPU (CUDA): 0.310 seconds 4 GPUs on my school's super computer (CUDA with static domain decomposition): 0.0547 seconds So here's my question - if we can get such huge speedups by programming the GPU instead of the CPU, why is nobody doing it??? I can think of so many things we could speed up like this, and yet I don't know of many commercial apps that are actually doing it. Also, what kinds of other speedups have you seen by offloading your computations to the GPU?

  • Include path of php.ini ignored by Eclipse

    - by Matthieu
    Hi all, I have a PHP script to run. If I run it from the command line, it works fine (include path is set correctly). If I want to run it inside Eclipse (Run as script), then the PHP include path of my php.ini is replaced by Eclipse, with all the libraries I've added to the project. I've configured my PHP executable in Eclipse. I've set the correct PHP executable file, and I selected my php.ini file too (the right one, I've checked). But it is ignored... Help please !

  • How to remotely connect to jmx on tomcat using ssh tunnelling and not break ehcache...

    - by Unsavory
    I've followed the instructions in the following link to create my own RMI registry and jmx server on a single port inside tomcat. According to the comments, I need to set -Djava.rmi.server.hostname=localhost. Once I do that, I can indeed connect to my server via jconsole using ssh port forwarding. http://blogs.sun.com/jmxetc/entry/connecting_through_firewall_using_jmx However, I've found it has the very bad side affect of breaking our ehcache replication which uses RMI. It fails complaining that it cannot bootstrap from remote peer localhost. I'm guessing because the peers all have their rmi server hostname set to localhost from setting -Djava.rmi.server.hostname=localhost. Does anyone have a possible workaround to this problem?

  • MVC2 Controller is passed a null object as a parameter

    - by Steve Wright
    I am having an issue with a controller getting a null object as a parameter: [HttpGet] public ActionResult Login() { return View(); } [HttpPost] public ActionResult Login(LoginViewData userLogin) { Assert.IsNotNull(userLogin); // FAILS if (ModelState.IsValid) { } return View(userLogin); } The LoginViewData is being passed as null when the HttpPost is called: Using MvcContrib.FluentHtml: <h2>Login to your Account</h2> <div id="contact" class="rounded-10"> <%using (Html.BeginForm()) { %> <fieldset> <ol> <li> <%= this.TextBox(f=>f.UserLogin).Label("Name: ", "name") %> <%= Html.ValidationMessageFor(m => m.UserLogin) %> </li> <li> <%= this.Password(u => u.UserPassword).Label("Password:", "name") %> <%= Html.ValidationMessageFor(m => m.UserPassword) %> </li> <li> <%= this.CheckBox(f => f.RememberMe).LabelAfter("Remember Me")%> </li> <li> <label for="submit" class="name">&nbsp;</label> <%= this.SubmitButton("Login")%> </li> </ol> </fieldset> <% } %> <p>If you forgot your user name or password, please use the Password Retrieval Form.</p> </div> The view inherits from MvcContrib.FluentHtml.ModelViewPage and is strongly typed against the LoginViewData object: public class LoginViewData { [Required] [DisplayName("User Login")] public string UserLogin { get; set; } [Required] [DisplayName("Password")] public string UserPassword { get; set; } [DisplayName("Remember Me?")] public bool RememberMe { get; set; } } Any ideas on why this would be happening? UPDATE I rebuilt the web project from scratch and that fixed it. I am still concerned why it happened.

  • How do I use a datetime variable with createparameter in classic ASP?

    - by Frank Schmitt
    I'm having a heck of a time trying to create a parameterized query that binds a date variable into a stored procedure call: twoyearsago = dateadd("yyyy", -2, date()) DataConn.ConnectionString = myConnectionString DataConn.Open Set rs = Server.CreateObject("ADODB.Recordset") Set DataCmd = Server.CreateObject("ADODB.Command") DataCmd.ActiveConnection = DataConn DataCmd.CommandText = "exec myStoredProc ?, ?" DataCmd.Parameters.Append DataCmd.CreateParameter("@start", adDate, , 10, date()) DataCmd.Parameters.Append DataCmd.CreateParameter("@end", adDate, , 10, twoyearsago) rs.Open DataCmd The stored proc returns nothing (indicating the dates aren't making it through). If I hard code dates in the query, e.g.: DataCmd.CommandText = "exec myStoredProc '01/01/2008', '01/01/2010'" I get the results I would expect. Calling CStr on my dates (if that makes a difference) returns them in the above format.

  • What exactly is the "Multi-threaded Debug DLL" Runtime Library option doing in VS 2008?

    - by GregH
    I have a solution in VS 2008 that creates a DLL. I then use that DLL in another application. If I go in to the DLL projects property pages and change the following configuration for a DEBUG build then the built dll no long provides the desired functionality. If I change it back and rebuild the DLL, then the DLL does provide the correct functionality: Property Pages = Configuration Properties = C/C++ = Code Generation = Runtime Library If set to "Multi-threaded Debug DLL (/MDd)" then everything works as it should. I get the correct functionality from the DLL If set to "Multi-threaded DLL (/MD)" then the DLL does not function properly...no runtime errors or anything, it just doesn't work (The DLL is supposed to plot some lines on a map but does not in this mode). So the question is, why does using the /MDd flag result in correction functionality of the underlying code, while /MD results in incorrect functionality? A little background...somebody else developed the DLL in C++ and I am using this DLL in a VB.net application.

  • Hide editor-label for public property when calling EditorFor(...)?

    - by FreshCode
    When calling Html.EditorFor(m => m), where m is a public class with public properties, a hidden input and a label are displayed for properties with the [HiddenInput] attribute. How can I hide the label without making it private or creating an editor template? Example public class User { [HiddenInput] public Guid ID { get; set; } // should not be displayed in editor template public string Name { get; set; } // should be editable } Undesired result for ID property by EditorFor(...) with label <div class="editor-label"> <label for="ID">ID</label> <!-- Why is this here? --> </div> <div class="editor-field"> <input id="ID" name="ID" type="hidden" value=""> </div>

  • MVC2 DataAnnotations validation with inheritance

    - by bhiku
    Hi, I have a .NET 2.0 class the properties of which are marked virtual.I need to use the class as a model in a MVC2 application. So, I have created a .NET 3.5 class inheriting from the .NET 2.0 class and added the DataAnnotations attributes to the overriden properties in the new class. A snippet of what I have done is below // .NET 2.0 class public class Customer { private string _firstName = ""; public virtual string FirstName { get { return _firstName; } set { _firstName = value; } } } // .NET 3.5 class public class MVCCustomer : Customer { [Required(ErrorMessage="Firstname is required")] public override string FirstName { get { return base.FirstName; } set { base.FirstName = value; } } } I have used the class as the model for a MVC2 view using the HtmlFor helpers. Serverside validation works correctly but the client side validation does not. Specifically the validation error is not displayed on the page. What am I missing, or is it only possible to do this using buddy classes. Thanks.

  • Interesting SQL Sorting Issue

    - by rofly
    It's crunch time, deadline for my most recent contract is coming in two days and almost everything is complete and working fine (knock on wood) except for one issue. In one of my stored procedures, I'm needing to return a result set as follows. group_id | name A101 | Craig A102 | Craig Z101 | Craig Z102 | Craig A101 | Jim A102 | Jim Z101 | Jim Z102 | Jim B101 | Andy B102 | Andy Z101 | Andy Z102 | Andy The names need to be sorted by the first character of the group id and also include the Z101/Z102 entries. By sorting strictly by the group id, I get a result set as follows: A101 | Craig A102 | Craig A101 | Jim A102 | Jim B101 | Andy B102 | Andy Z101 | Andy Z102 | Andy Z101 | Jim Z102 | Jim I really can't think of a solution that doesn't involve me making a cursor and bloating the stored procedure up more than it already is. I'm sure a great mind out there has an elegant solution and I'm eager to see what the community can come up with. Thanks a ton in advance.

  • MVVM && IOC && Sub-ViewModels

    - by Lee Treveil
    I have a ViewModel, it takes two parameters in the constructor that are of the same type: public class CustomerComparerViewModel { public CustomerComparerViewModel(CustomerViewModel customerViewModel1, CustomerViewModel customerViewModel2) { } } public class CustomerViewModel { public string FirstName { get; set; } public string LastName { get; set; } } If I wasn't using IOC I could just new up the viewmodel and pass the sub-viewmodels in. I could package the two viewmodels into one class and pass that into the constructor but if I had another viewmodel that only needed one CustomerViewModel I would need to pass in something that the viewmodel does not need. How do I go about dealing with this using IOC? I'm using Ninject btw. Thanks

  • TFS Load Testing Web Tests

    - by durilai
    I am configuring a load test and am curious/confused on settings. I am testing an intranet website, that is expected to have 6000 concurrent users. My employer had some previous consultant tell them that the load test users does not matter and that we need to worry about requests/second. They have previously determined that those 6000 users would generate 30 rps, while I feel that is not correct we need to show that we can exceed that number. The previous load test was set for only 200 users and the results showed that it did exceed the 200 rps. They were happy with the results, but that is not how I understand this. My question is, if we need to support 6000 concurrent users should I just set my users to 6000 and run, or is the rps an adequate piece of data to rely on? Any help is appreciated. Thanks

  • How to use Win32 SetCursor() with WPF resource and HwndHost

    - by Hank
    We have an HwndHost UIElement in our WPF application which is used to display Direct3d graphics, and the only way I have found to set a cursor for the HwndHost UIElment is to call the Win32 API SetCursor(). All of our cursors are resources in managed assemblies, and I would prefer to not change that, but I have not been able to find a way to load one of these cursors via any Win32 APIs like LoadImage(). Does anybody know how to get a handle(hCursor) to a cursor which is a resource in a managed assembly? Or, is there another way to set a cursor on an HwndHost displaying Direct3D graphics?
