  • ASP.NET Web API crash MSVCR90.dll

    - by user858931
    I have a web api app developed on VS2010. The application calls an external program to run and it runs just fine if I execute in VS2010. But then when I deploy the web api to IIS 7 and 7.5, in some cases, it crashes. Below is the details I got from Event Viewer/Appliation: Fault bucket , type 0 Event Name: BEX Response: Not available Cab Id: 0 Problem signature: P1: TestProgram.exe P2: 1.0.4728.17141 P3: 50c76dea P4: MSVCR90.dll P5: 9.0.30729.6161 P6: 4dace5b9 P7: 0003024a P8: c0000417 P9: 00000000 P10: Attached files: These files may be available here: C:\ProgramData\Microsoft\Windows\WER\ReportQueue\AppCrash_InferenceGenerat_95abb43ace91480da6b8f27f9937db667bc58f_7bb1549d Analysis symbol: Rechecking for solution: 0 Report Id: da8f304e-44c0-11e2-b4e8-0026b97a5242 Report Status: 0 Any idea why it happens and how to fix it?

  • Passing contextual info to Views in ASP.NET MVC

    - by Andrey
    I wonder - what is the best way to supply contextual (i.e. not related to any particular view, but to all views at the same time) info to a view (or to master page)? Consider the following scenario. Suppose we have an app that supports multiple UI languages. User can switch them via UI's widgets (something like tabs at the top of the page). Each language is rendered as a separate tab. Tab for the current language should not be rendered. To address these requirements I'm planning to have a javascript piece that will hide current's language tab on the client. To do this, I need current's language tab Id on the client. So, I need some way of passing the Id to master page (for it to be 'fused' into the js script). The best thing I can think of is that all my ViewModels should inherit some ViewModeBase that has a field to hold current language tab Id. Then, whatever View I'm rendering, this Id will always be available for the master page's hiding script. However, I'm concerned that this ViewModelBase can potentially grow in an uncontrolled fashion as number of such pieces of contextual info (like current language) will grow.. Any ideas?

  • how to protect an imported win32 dll into a .net application from memory issues

    - by Eric
    I have a c# application that needs to use a legacy win32 dll. The dll is almost its own app, it has dialogs, operations with hardware, etc. When this dll is imported and used, there are a couple of problems that occur: Dragging a dialog (not a windows system dialog, but one created by the dll) across the managed code app causes the UI to not repaint. Further it generates a system out of memory exception from various ui controls. The performance is incredibly slow. There seems to be no way to unload the dll so the memory never gets cleaned up. When we close our managed app, we get another memory exception. At the moment we import each method call as such: [DllImport("dllname.dll", EntryPoint = "MethodName", SetLastError = true, CharSet = CharSet.Auto, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]

  • resource embedding in asp.net

    - by Mike
    I have a project which needs to generate PDF documents. I am using iTextSharp. I have a pdf which needs to be read and then appended to. To read the pdf document, I'm using PdfReader(), which accepts many forms, but I can't figure out how to reference a pdf in my webapplication to PdfReader. My host does not allow Binary Serialization (apparently that's bad), so I don't think I can load from an embedded resource. I've tried just using PdfReader("report.pdf"), but it keeps throwing an exception telling me that the file isn't found. I've tried putting the file in the bin directory, root directory, in the same directory as the class, but this still doesn't work. It works if I use a fully qualified path to the pdf document, but I can't use that when I upload it to my hosting provider. Does anyone have any suggestions on how I should do this? Thanks

  • size of structures in .NET

    - by redpaladin
    My problem is very simple. My problem is to send a structure between a program in C to a C# program. I made a struct in C#: public struct NetPoint { public float lat; // 4 bytes public float lon; // 4 bytes public int alt; // 4 bytes public long time; // 8 bytes } Total size of the struct must be 20 bytes. When I do a sizeof() of this struct: System.Diagnostics.Debug.WriteLine("SizeOf(NetPoint)=" + System.Runtime.InteropServices.Marshal.SizeOf(new NetPoint())); The debug console shows: SizeOf(NetPoint)=24 But I expected to have 20 bytes. Why do I see a difference?

  • WCF publish/subscribe service, and ASP.NET MVC client

    - by d3j4vu
    I managed to develop a custom WCF service, using the publish / subscribe model, and hosted inside a managed windows service. Everything's working. I developed an interface as the service contract implementing a method definition marked as a non-one way operation contract (OperationContract(IsOneWay = false)]. This, to make possible returns an instance of a custom class derived from System.Web.Mvc.ActionResult. In the MVC app, event fires ok. It wraps inside an action method, (just the one defined in the interface), but, and this is my current problem, i believe that something relative to the execution context of the windows service (and the hosted wcf counterpart) blocks the execution of the action method in the MVC app. This is what i have until now (some pieces ripped off just to be more clear): /// Method definition for the contract's service. Maps to a MVC ActionMethod. [OperationContract(IsOneWay = false)] ActionResult Imagen(string data, CustomActionResult result); The class to hold an ActionResult derived class instance: public class ServiceEventArgsMvc : ServiceEventArgs { /// <summary> /// /// </summary> public CustomActionResult Result { get; set; } } And the code in the MVC client app: /// <summary> /// Just a simple class to hold an abstract ActionResult derived class instance. /// </summary> public ActionResult Image(string data, CustomActionResult result) { ViewData["data"] = data; return View(); } Ok. ActionMethod sucessfully executes...but when it's done (and usually expected obtain a reditection to a View named Image, like the action method), the WCF service throws a Timeout exception, making clear that he's still waiting for a response from the MVC client. The response never arrives, so the MVC app never finish his work (redirect to the "Image" view as expected). Any ideas?. Guess i'm missing something very simple, but i don't know what it could be. This is drivin' me nuts.

  • asp.net gridview bind dateformat not working with update

    - by Brabbeldas
    I have a GridView with a TemplateField column which shows a DateTime from a DataSource. <Columns> <asp:CommandField ShowEditButton="True" /> <asp:TemplateField HeaderText="Start Date"> <EditItemTemplate> <asp:TextBox ID="txtDateStart" runat="server" Text='<%# Bind("dtDateStart", "{0:dd/MM/yyyy}") %>'</asp:TextBox> </EditItemTemplate> <ItemTemplate> <asp:Label ID="Label1" runat="server" Text='<%# Bind("dtDateStart", "{0:dd/MM/yyyy}") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> </Columns> Displaying the date in the correct format works as it should. Note that the format starts with DAY followed by MONTH. When I switch to edit mode, change the date in the TextBox to '31-01-2013' and press the GridView's update-link i get an error: Cannot convert value of parameter 'dtDateStart' from 'System.String' to 'System.DateTime' The error is generated by the GridView not my own code. It happens before the UpdateMethod of my DataSource is called. When i type '01-31-2012' the data is processed correctly and the value is updated into the database. Somehow when the date is displayed it uses format dd-MM-yyyy (just as I need it to) But when it reads the new value form the TextBox it uses MM-dd-yyyy Can somebody please help me?

  • ASP.NET MVC routing and paths is js files

    - by HiveHicks
    Hello, we're facing a problem now. We have a pretty big page with a loooong inline script, which does all the work. We now want to obfuscate it and use it as a separate .js file. But the problem is that we have paths which are generated by Url helper (Url.Content()). So what is the best way to separate js file from the page and not using hard-coded path strings?

  • Unique visitor counting in ASP.NET MVC

    - by Max
    I'd like to do visitor tracking similar to how stackoverflow does it.. By reading through numerous posts, I've figured out some details already: Count only 1 IP hit per 15 minutes (if anonymous) Count only 1 unique user-Login (per day?) Now that leaves the question of the real implementation.. Should I log the two factors live into a table (and increase count) | IP | timestamp | pageurl | Or do the counting AFTERWARDS (e.g. using IIS log files - which don't include the user, right? I know there're some similar posts outside, but NONE really has a great solution in my opinion yet..

  • asp.net mvc 2 multiple partial view

    - by 303
    Hey Guys, I have a contoller that renders 3 different views. But I also have a common part (div) for every view. I thought that I can create an UserControl with own controller and include that control on my views (New controller and view as controll). How should I use that UserControl? Should it be a partial view? Or different approach - can I have multiple partial views on one page? I've been searching the web for the last view days and haven't found working solution that suits me. Also I want to use Strongly Typed views/data. Cheers

Question: So what is the correct way to tie an dropdown/radio buttion/... ASPX value to a constant that is shared with the CodeBehind code? I know that I could do rbServer.Add.Item("developer") [from the CodeBehind], but is there a way to achieve it from the Presentation side of things?

  • Validating primitive types in ASP.NET MVC

    - by Alex
    I've implemented the following classes to validate data public abstract class Validated { public bool IsValid { get { return (GetRuleViolations().Count() == 0); } } public abstract IEnumerable<RuleViolation> GetRuleViolations(); } public partial class User: Validated { public override IEnumerable<RuleViolation> GetRuleViolations() { if (this.Age < 1) yield return new RuleViolation("Age can't be less than 1"); } } It works great! When the form is submitted I just do if (user.IsValid == false) blah... But I still need to validate that the Age is an integer int a = 0; if (!int.TryParse(age, out a)) { error = "Not integer"; // ... } How can I move this to my model?

Any way I could specify that in all cases, the conversion will indeed be possible (I'm basically getting integers, booleans, doubles and strings). Thanks!

  • Any .NET '#region directive' convention ideas ?

    - by PaN1C_Showt1Me
    I really appreciate the possibility to define regions in your code, as it improves the readability insanely. Anyways, I'd like to have everyone using the same convention in all classes (with the predefined order of all regions) like: Private Fields Constructors Class Properties Event Handlers etc... Do you have any proposition how this division could look like (What regions have sense and what names should they have) and in which order should they be defined ?
