  • `DesignMode` in subcontrols is not set correctly?

    - by affan
    I have a compound control contains nested controls. The problem i am facing is that control read properties from a global setting class which is static and intern read from setting file. To stop individual control from accessing configuration in design mode i added check in each control. If(!DesignMode){ ... //Initialize properties e.g. prop = AppConfig.GetProperty("prop1"); } The problem is that individual control work fine when open in VS. But when i open top control containing nested control i get error by VS designer. The error is that in a nested control DesignMode=false for some reason. I also created a test app and created a simple control within another control to test if there is a problem with VS but it seem to work correctly for any depth of controls. I dont even know how to debug this. For now i comment out the property initializing code and build it and then open designer and there uncomment it and build it again to run it. Did anyone came across this problem or is there any way to fix it.

  • T-SQL: Dynamic Query by Selected Column in ASP.NET GridView

    - by jp2code
    I'm trying to modify a stored procedure used in an ASP.NET page. By default, the stored procedure returns all of the data, which can be overwhelming for employees in the plant. I want to add a drop down menu item for the column name and a text box for a value to allow our employees to search the data for their specific items. What I would like to add is the ability to pass in a Column Name and Column Value to search, similar to the following: DECLARE @colName nVarChar(50), @colValue nVarChar(50) SET @colName='EmployeeID' SET @colValue='007135' SELECT Column1, Column2, Column3, Column4, Column5, Column6, Column7 FROM viewNum1 WHERE ((@colName IS NULL) OR (@colValue IS NULL) OR ('['+@colName+']'=@colValue)) If all values passed in (@colValue and @colName), all records return; however, if I try specifying that @colName=EmployeeID and @colValue='007135' (a value that does exist in the database), no records are returned. Next is the problem that I am running an old SQL Server 2000 database that does not allow the stored procedure to access the table column names, and the whole technique looks prone to SQL Injection. Finally, I don't see how to bind my GridView control to this and still have the ability to display all records. How would I write such a filtering stored procedure?

  • how many color combinations in a 24 bit image

    - by numerical25
    I am reading a book and I am not sure if its a mistake or I am misunderstanding the quote. It reads... Nowadays every PC you can buy has hardware that can render images with at least 16.7 million individual colors. Rather than have an array with thousands of color entries, the images instead contain explicit color values for each pixel. A 24-bit display, of course, uses 24 bits, or 3 bytes per pixel, for color information. This gives 1 byte, or 256 distinct values each, for red, green, and blue. This is generally called true color, because 256^3 (16.7 million) He says 1 byte is equal to 256 distinct values. 1 byte = 8 bits. 8^2 bits = 64 combinations of colors right ?? It's not adding up right to me. I know it might be something simple to understand, but I don't understand.

  • vs2008 attach to process, can't see which process

    - by Mafti
    Hi, In vs2003 (and vs2005(not sure about that)) when I attached to a process, before actually attaching I could see which process were running under w3wp (I have a couple of websites running locally) so I knew which exact .net application I was about to debug. however in vs2008 the window doesn't show up anymore.. now I have to attach it, come to the conclusion it was the wrong process, stop debugging and attach it to the other process (if I haven't forgot teh processid :P ) Is there a way to "enable" that interesting window to see with .net apps are runnig in that specific w3wp process? or am i missing something obvious?

  • MFC/WIN32: mouse hover highlight in listctrl

    - by Mordachai
    The ListView control of Windows Explorer gives a highlight to whatever item is under the mouse, without affecting the current selection. This helps enormously with relating what item a given tooltip applies to within a listview - especially in report mode. However, I am currently unable to find any APIs that would give my MFC application's CListCtrl that same behavior. Extended styles only have LVS_EX_TRACKSELECT, which actually alters the current selection (yuck!). Does anyone know how to provide a standard CListCtrl (or whatever that actually sits on top of) the mouse-hot-tracking capability? I found some articles on how to provide per cell and per row tooltip text, but its hard to tell what the tooltips relate to without something highlighting...

  • Need help understanding .net ThreadPool

    - by Meredith
    I am trying to understand what ThreadPool does, I have this .NET example: class Program { static void Main() { int c = 2; // Use AutoResetEvent for thread management AutoResetEvent[] arr = new AutoResetEvent[50]; for (int i = 0; i < arr.Length; ++i) { arr[i] = new AutoResetEvent(false); } // Set the number of minimum threads ThreadPool.SetMinThreads(c, 4); // Enqueue 50 work items that run the code in this delegate function for (int i = 0; i < arr.Length; i++) { ThreadPool.QueueUserWorkItem(delegate(object o) { Thread.Sleep(100); arr[(int)o].Set(); // Signals completion }, i); } // Wait for all tasks to complete WaitHandle.WaitAll(arr); } } Does this run 50 "tasks", in groups of 2 (int c) until they all finish? Or I am not understanding what it really does.

  • 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); }

  • Updating an image's ImageUrl within a Repeater

    - by Django Reinhardt
    I hope someone can help me. It's a pretty newbie question, I'm afraid. I have an image inside a repeater, and I would like to change its IMAGEURL based on parameter that's being passed to it. <asp:Repeater ID="Repeater" runat="server"> <HeaderTemplate> <asp:Image ID="imgType" runat="server" /> </HeaderTemplate> <ItemTemplate> <%# Eval("DisplayName")%> </ItemTemplate> <SeparatorTemplate> <hr /> </SeparatorTemplate> </asp:Repeater> There is a SWITCH statement in the code behind that is altering the IMAGEURL depending on what's being passed to it. Inevitably, however, the images ID ("imgType") is not visible to the SWITCH statement (presumably because it's inside a REPEATER). Any suggestions on the best way to implement this would be greatly appreciated. Sorry for such a newbie question.

  • How to handle when SSRS does not automatically update fields based on database query?

    - by badpanda
    So I am trying to change the number of fields in my dataset in SSRS and the refresh button is not picking up the added field from the SQL server. The query is definitely returning the correct data, as I have double checked in the server engine itself. Also, I have tried manually adding the field using the SSRS menu, but as soon as I execute it disappears. Any suggestions or similar experiences?

  • How does the VS XAML designer know what to auto-populate certain values with?

    - by Pwninstein
    <Button Name="MyButton" Content="Test" FontStyle="Italic" /> In the above XAML definition of a button, the FontStyle property is set to Italic. The designer is somehow able to populate a list for me to choose from when I hit the = sign. How is this achieved? Before you answer, consider that the FontStyle property is, appropriately enough, of type FontStyle (which is a struct). It's not an enumeration, which would be trivial for VS to list out at design time, so how are the valid list of options chosen to be displayed? There is also a completely separate FontStyles class which contains three static fields, Italic, Normal, and Oblique which just so happen to be the three items VS provides in the drop down list. Is there some mapping going on behind the scenes between the FontStyle struct and FontStyles class, because I've looked in many places in both the object browser and in .NET Reflector and couldn't determine anything from either. Thanks!! I NEED to know!* *Not really, but it would be nice to :)

  • Developing a 2D Game for Windows Phone 8

    - by Vaccano
    I would like to develop a 2D game for Windows Phone 8. I am a professional Application Developer by day and this seems like a fun hobby. But I have been disapointed trying to get going. It seems that 2D games (far and away the majority of games) do not have any real support. It seems the Windows Phone makers did not include support for Direct2D. So unless you are planning to make a fully 3D app, you are out of luck. So, if you just wanted to make a nice 2D app, these are your choices: Write your game using Xaml and C# (Performance Issues?) Write your game using Direct3D and but only draw on one plane. Use the DirectX Took Kit found on codeplex. It allows you to use the dying XNA framework's API for development. Number 3 seems the best for my game. But I hate to waste my time learning the XNA api when Microsoft has clearly stated that it is not going to be supported going forward. Number 2 would work, but 3D development is really hard. I would rather not have to do all that to get the 2D effect. (Assuming Direct2D is easier. I have yet to look into that.) Number 1 seems the easiest, but I worry that my app will not run well if it is based off of xaml rendering rather than DirectX. What is the suggested method from Microsoft? And who decided that 2D games were going to get shortchanged?

  • Accidentally created VB.NET project instead of C#

    - by Bryan M.
    This should seem simple enough, but can't figure it out. I was porting a project out of MonoDevelop and into VS2008, but I accidently created the project as VB.NET instead of C#. Now ReSharper and any syntax highlighting is throwing a fit because it's trying to validate it as VB. How do I tell it to treat it as a C# project without creating a whole new one?

  • VS 2010 / Resharper 5 Mouse Behavior

    - by Berryl
    After upgrading to the above configuration I notice that 1) CTRL-Click on a type highlights the type but doesn't take me to the declaration, 2) Clicking on some closure (ie, like a method) toggles whether it's expanded or collapsed. Since these are both mouse related tasks I figure there is some setting in either VS or R# that I need to change, but I sure can't figure out what it is. Anybody know? Cheers, Berryl PS - there is an option in R# to ctrl-click to the type but I have that checked and it still does not work.

  • How to setup Expression Blend 3 add-in window at certain position ?

    - by j23tom..pl
    For example in Sketchflow add-in there is ApplicationFlowPane (derrived from PrototypingPane) which registers itself using IWindowService like this: service.RegisterPalette(this.PaletteRegistryName, this, this.Caption, this.KeyBinding); But i can't see where it is defined that it is docked on bottom pane. Before someone replies that it's at: %AppData%\Microsoft\Expression\Blend3\Workspaces No it's not there because those files do not exists at first run. The question is how can i put my window at certain position with Expression Blend 3 plug-in api ? update 1: It seems that to achive what i want i have to change design.xaml (where workspaces are defined) which is loaded from satellite assembly Microsoft.Expression.Blend.resources.dll (method load in class FrameworkPackage in Microsoft.Expression.Blend.dll). But since this dll is strongly named i can't change it. So now the question is. Is there any other way I can change Design Workspace at runtime ?

  • C# VS 2008 Build Configurations - using different classes for different builds

    - by evan
    I'm writing an application which has two classes that provide basically the same functionality but for different situations. I'd like to have three versions of the software - one where the user can change an ini file to configure the program to use one of the two classes, and then one version that only uses one of the two classes. Right now I have it working via an ini file, but I'd like to be able to build versions that don't include the code for the unneeded class at all. What is the best way to go about this? My current line of thinking is that since both classes derive from a common interface I'll just add a compile time conditional that looks at the active build configuration and decides whether to compile that class. What is the syntax to do that? Thanks in advance for your help and input!
