  • Why does a Silverlight application show a blank browser screen when created from exported template?

    - by Edward Tanguay
    I created a silverlight app (without website) named TestApp, with one TextBox: <UserControl x:Class="TestApp.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480"> <Grid x:Name="LayoutRoot"> <TextBlock Text="this is a test"/> </Grid> </UserControl> I press F5 and see "this is a test" in my browser (firefox). I select File | Export Template | name it TestAppTemplate and save it. I create a new silverlight app based on the above template. The MainPage.xaml has the exact same XAML as above. I press F5 and see a blank screen in my browser. I look at the HTML source of both of these and they are identical. Everything I have compared in both projects is identical. What do I have to do so that a Silverlight application which is created from my exported template does not show a blank screen? (creating a WPF application from an exported template like this works fine)

  • How to validate DataReader is actually closed using FxCop custom rule?

    - by tanmay
    I have written couple of custom rules in for FxCop 1.36. I have written code to find weather an opened DataReader is closed or not. But it does not check which DataReader object is calling the Close() method so I can't be sure if all opened DataReader objects are closed!! 2nd: If I am a DataReader in an 'if/else' like if 1=2 dr = cmd.ExecuteReader(); else dr = cmd2.ExecuteReader(); end if In this case it will search for 2 DataReader objects to be closed. I am putting my code for more clarity. public override ProblemCollection Check(Member member) { Method method = member as Method; int countCatch =0; int countErrLog = 0; Instruction objInstr = null; if (method != null) { for (int i = 0; i < method.Instructions.Count; i++) { objInstr = method.Instructions[i]; if (objInstr.Value != null) { if (objInstr.Value.ToString() .Contains("System.Data.SqlClient.SqlDataReader")) { countCatch += 1; } if (countCatch>0) { if (objInstr.Value.ToString().Contains( "System.Data.SqlClient.SqlDataReader.Close")) { countErrLog += 1; } } } } } if (countErrLog!=countCatch) { Resolution resolu = GetResolution(new string[] { method.ToString() }); Problems.Add(new Problem(resolu)); } return Problems; }

  • Why does VS2005 skip execution of lines when debugging managed C++ without optimizations?

    - by Sakin
    I ran into a rather odd behavior that I don't even know how to start describing. I wrote a piece of managed C++ code that makes calls to native methods. A (very) simplified version of the code would look like this (I know it looks like a full native function, just assume there is managed stuff being done all over the place): int somefunction(ptrHolder x) { // the accessptr method returns a native pointer if (x.accessptr() != nullptr) // I tried this with nullptr, NULL, 0) { try { x->doSomeNativeVeryImportantStuff(); // or whatever, doesn't matter } catch (SomeCustomExceptionClass &) { return 0; } } SomeOtherNativeClass::doStaticMagic(); return 1; } I compiled this code without optimizations using the /clr flag (VS.NET 2005, SP2) and when running it in the debugger I get to the if statement, since the pointer is actually null, I don't enter the if, but surprisingly, the cursor jumps directly to the return 1 statement, ignoring the doStaticMagic() method completely!!! When looking at the assembly code, I see that it really jumps directly to that line. If I force the debugger to enter the if block, I also jump to the return 1 statement after I press F10. Any ideas why this is happening? Thanks, Ariel

  • Howw to add new value with generic Repository if there are foreign keys (EF-4)?

    - by Phsika
    i try to write a kind of generic repository to add method. Everything is ok to add but I have table which is related with two tables with FOREIGN KEY.But Not working because of foreign key public class DomainRepository<TModel> : IDomainRepository<TModel> where TModel : class { #region IDomainRepository<T> Members private ObjectContext _context; private IObjectSet<TModel> _objectSet; public DomainRepository() { } public DomainRepository(ObjectContext context) { _context = context; _objectSet = _context.CreateObjectSet<TModel>(); } //do something..... public TModel Add<TModel>(TModel entity) where TModel : IEntityWithKey { EntityKey key; object originalItem; key = _context.CreateEntityKey(entity.GetType().Name, entity); _context.AddObject(key.EntitySetName, entity); _context.SaveChanges(); return entity; } //do something..... } Calling REPOSITORY: //insert-update-delete public partial class AddtoTables { public table3 Add(int TaskId, int RefAircraftsId) { using (DomainRepository<table3> repTask = new DomainRepository<table3>(new TaskEntities())) { return repTask.Add<table3>(new table3() { TaskId = TaskId, TaskRefAircraftsID = RefAircraftsId }); } } } How to add a new value if this table includes foreign key relation

  • Include a version control tag in VSS

    - by Sjuul Janssen
    I was reading Code Complete 2 and it mentions this: Many version-control tools wil insert version information into a file. In CVS, for exmple the characters // $id$ Will Automaticly expand to // $id: ClassName.java, v 1.1 2004/02/05 00:36:42 ismene Exp $ So now I would like to do something similar with VSS for our SQL scripts I have been googling around for the answer but can't find it. Is this possible? can someone maybe point me in the right direction?

  • How to restart the IIS Site when re-compiling an asp.net website

    - by Glennular
    What is the best way to add into the build/compile script of an Asp.net project to initiate a IIS to restart the website on DLL rebuild instead of the first request to the site. Current Process Compile Project Wait Hit APSX Page IIS starts reload Wait Page loads Ideal process: Compile Project & Reload IIS Wait Hit APSX Page Page loads The first way I though of was add a request to just hit one of the pages in the "Post-Build events". Just wondering best practices. This would be similar to "Start" which opens a page immediately on build.

  • Accented character regex

    - by user314573
    I'm trying to create a regex that will look for french words whether a user specifies the accented characters or not. So if the the user has searched for "déclaré" but types in declare instead I would like to be able to match the text still. I'm having difficulty making this more dynamic so that it can be matched on any french word... Closest example from another user from a different post was: d[eèéê]cl[aàáâ]r[eèéê] Is it even possible to write a regex for something like this? Any advice would be much appreciated.

  • Change right-click context menu options in VS2008

    - by Mark Ursino
    When I right-click in my class library, I get some quick options to create things, like an Item from the popup list (New Item...), a User Control, etc. E.g. Now in my web app project, I'd like to be able to get the User Control listed in the right-click menu just like Component and Class, so I don't have to click New Item... then choose it from there. Is there a way to do this in the configuration? I can't seem to figure it out in VS.

  • VS2010 Code Analysis, any way to automatically fix certain warnings?

    - by JL
    I must say I really like the new code analysis with VS 2010, I have a lot of areas in my code where I am not using CultureInfo.InvariantCultureand code analysis is warming me about this. I am pretty sure I want to use CultureInfo.InvariantCulturewhere ever code analysis has detected it is missing on Convert.ToString operations. Is there anyway to get VS to automatically fix warnings of this type?

  • Allocated Private Bytes keeps going up in one computer but not the other

    - by Jacob
    OK, this may sound weird, but here goes. There are 2 computers, A (Pentium D) and B (Quad Core) with almost the same amount of RAM. If I run the same code on both computers, the allocated private bytes in A never goes down resulting in a crash later on. In B it looks like the private bytes is constantly deallocated and everything looks fine. In both computers, the working set is deallocated and allocated similarly. Could this be an issue with manifests or DLLs (system)? I'm clueless. Note: I observed the utilized memory with Process Explorer.

  • VS2005 Compilation Problem with Settings

    - by vijay.j
    I am trying to integrate PJNSMTPCONNECTION CLASSES in my project; they say that those classes do not use MFC. My project is with the setting like MT, and using standard library linking. When I try to compile, I am getting CSTRING not defined and fatal error C1189: #error : WINDOWS.H already included. MFC apps must not #include <windows.h> If I include afx.h and remove windows.h, I am getting iDLLMain already defined errors. How do I resolve these problems, please?

  • Problems encountered in changing a CRichEditCtrl selection color.

    - by dev ray
    I have written the following code after creating the CRichEditCtrl // 06112010 : The following code was added to highlight the textselection in black color instead of the default blue color of CRichEditCtrl. - 1311 { m_EditControl.SetSel(0,100); CHARFORMAT2 cf1; cf1.cbSize = sizeof(CHARFORMAT2); m_EditControl.GetSelectionCharFormat(cf1); cf1.dwMask = CFM_BACKCOLOR ; cf1.dwEffects &= ~CFE_AUTOBACKCOLOR; cf1.crBackColor = RGB(0,0,0); m_EditControl.SetSelectionCharFormat(cf1); m_EditControl.Invalidate(); } After this I am adding text, but the selection still comes in blue color instead of Black. Could someone please tell me what I am doing wrong?? Thanks, DeV

  • Time is updating when a form is not even running

    - by onaclov2000
    A co-worker of mine had downloaded a vb example project a while back to see how to make a call or two, he discovered it today again, and noticed that while sitting in the IDE the time/date is updating automatically when the entire project is not even running. How does this work, we looked around for code but can't find anything giving it away. Any ideas?

  • Extra space while installing .msi

    - by Cristina
    I have extra space in my custom made .msi. The data to be installed has about 600MB and the installer says it needs 1.4 GB.Switching to a different location then the predetermined one (e.g from C:\Program Files\My_App to F:\My_App) shows that it always need approximately 800 MB on the Windows partition, which is in my case the extra space. Any thoughts on why is this happening? Also can this cause an installation error on a 64-bit OS? I've only installed it on a 32-bit OS and everything is fine, but one of my colleagues is having problems installing it on the above mentioned type.

  • How to detect a Socket disconnection?

    - by AngryHacker
    I've implemented a task using the async Sockets pattern in Silverlight 3. I started with Michael Schwarz's implementation and built on top of that. So basically, my Silverlight app establishes a persistent socket connection to a device and then data flows both ways as necessary between the device and the Silverlight app. One thing I am struggling with is how to detect disconnection. I could think of 2 approaches: Keep-Alive. I know this can be done at the Sockets level, but I am not sure how to do this in an async model. How would the Socket class let me know there has been a disconnection. Manual keep alive. Basically, I am having the Silverlight app send a dummy packet every 20 seconds or so. If it fails, I'd assume disconnection. However, incredibly, SocketAsyncEventArgs.SocketError always reports success, even if I simply unplug the device that the Silverlight app is connected to. I am not sure whether this is a bug or what or perhaps I need to upgrade to SL4. Any ideas, direction or implementation would be appreciated.

  • Why initialize an object to empty

    - by ProgEnthu
    I am learning windows programming with the help of MSDN.Why would somebody initialize an object like the following? WNDCLASS wc = { }; Will this zero all the memory of the object? Whole source code is following: #ifndef UNICODE #define UNICODE #endif #include <windows.h> LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam); int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE, PWSTR pCmdLine, int nCmdShow) { // Register the window class. const wchar_t CLASS_NAME[] = L"Sample Window Class"; WNDCLASS wc = { }; wc.lpfnWndProc = WindowProc; wc.hInstance = hInstance; wc.lpszClassName = CLASS_NAME; RegisterClass(&wc); // Create the window. HWND hwnd = CreateWindowEx( 0, // Optional window styles. CLASS_NAME, // Window class L"Learn to Program Windows", // Window text WS_OVERLAPPEDWINDOW, // Window style // Size and position CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, NULL, // Parent window NULL, // Menu hInstance, // Instance handle NULL // Additional application data ); if (hwnd == NULL) { return 0; } ShowWindow(hwnd, nCmdShow); // Run the message loop. MSG msg = { }; while (GetMessage(&msg, NULL, 0, 0)) { TranslateMessage(&msg); DispatchMessage(&msg); } return 0; } LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam) { switch (uMsg) { case WM_DESTROY: PostQuitMessage(0); return 0; case WM_PAINT: { PAINTSTRUCT ps; HDC hdc = BeginPaint(hwnd, &ps); FillRect(hdc, &ps.rcPaint, (HBRUSH) (COLOR_WINDOW+1)); EndPaint(hwnd, &ps); } return 0; } return DefWindowProc(hwnd, uMsg, wParam, lParam); }
