• .NET Development AddRange

  For example I have the following code class Base { } class Derived : Base { } ... List<Derived> derivedList = new List<Derived>(); derivedList.AddRange( new Derived[] { new Derived(), new Derived() }; List<Base> baseList= new List<Base>(); baseList.AddRange(derivedList); // cant do this! Why cant I add a List of Derived to a List of Base with AddRange Why has it been designed that way Is there any particular reason for that I am from c++ background Why AddRange doesnt have the following interface void AddRange<T2>(IEnumerable<T2> elems) where T2 : T So that we can write something like class Foo{} class Bar : Foo {} FullList<Bar> bars = new FullList<Bar>(); bars.AddRange(new Bar[] { new Ba ...Show All

• Visual Basic Form Refresh During extensive process

  Hi, I need to refresh a winform (vb.net 2005) during an extensive process. The process is a DTS package execution (the process takes more than 5 minutes). I need to show to the user in a listbox the failure or success of every steps in the package during their execution. The form seems to frozen and even i use a timer to refresh it, it doesnt work. I tried the Application.DoEvents() too...but nothing seems to work. any idea sample code Thanks mcrisf application.doevents is bad practice - can cause unpredicatable results at times. The best thing to do in such a situation, when a process is time consuming is to use Threading. Threading will make your app respond and the way it works is that in a ...Show All

• Windows Forms Slow User Defined Control

  I'm creating a custom control that has contained within it a large number of buttons. The code is extremely slow (taking about 12 seconds to display). I've had no success in making it faster. The problem seems to be centered around a single statement: Controls.Add(my_button_ctl); I tried to use the Controls.AddRange(...) member instead of Add(), but there was no speed improvement as was implied in the documentation. If I remove the Controls.Add() call (or AddRange), the display is almost instant. Is anyone aware of a way to speed up a user defined control that contains a large number of button controls In my case there are up-to 550 buttons contained on the control and I would like to get them displayed in under 1 second. The custom ...Show All

• Visual Studio Has anyone got the "TypeBrowser" working?

• SQL Server Cube Partitions Setup

  I have use the cube partitions in AS2000. It allows us to use the data slice to define the subset of the cube data. However, I don't see this in AS2005. If I partition the cube in monthly basis, then how AS2005 to handle the query. Is it look through all the partitions since it don't have the data slice setup In AS2005 partition slices are defined bit differently. To define what data should go into partition you can define partition binding. You can change source for your partition to define restriction on the data coming into Analysis Services. As for Anlaysis Services, it will detect the slice automatically. ( this is MOLAP case) Edward. -- This posting is provided "AS IS" with no warranties, and confers no r ...Show All

• Software Development for Windows Vista Custom Activities and adding to the Toolbox

  I've created a custom activtiy derived / inherited from the HandleExternalEvent. It compiles fine. When I try to add it to an Activity Library by going to the ToolBox and selecting Choose Items / Activities and Browse to the DLL, it gives me "System.ArgumentException: Toolbox Service not found as Microsoft.Workflow.VSDesigner.ActivitiesToolboxPage.AddComponentsDialog.AddItems(string Filename)" I've also tried adding this custom activity directly to a Sequential Workflow instead and I get the same thing.

Try deriving from CompositeActivity and see if you are getting the same error message. And last ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Blitting?

  I've checked through the XNA Documentation, but there doesn't seem to be any way to 'blit'. For those of you unfirmiliar with 'blit': Blit is a way to draw something. For example, say you create a "Texture2D" variable, set the size etc... But the texture is blank. The normal way to create a texture to this is to load up a bitmap image with it through the ContentManager, right But what if you want to use a whole sprite-sheet with many images Back to the blank, say, 65 x 65 bitmap image, you obviusly don't want this 2D image of the player to be a whole 1024x768 sprite-sheet. So this is where I used blitting in other programs, it basically asks for the x, y co-ordinates, and the length of the bitmap and takes a picture from that x,y and 'c ...Show All

• SQL Server Problems with performance when programmatically printing large amounts of pages

  We are using VB.NET 2005 to develop a WinForms application that uses SQL Server 2005 Reporting Services to produce reports. Originally we tried  using code found on Bryan's WebLog,  http://blogs.msdn.com/bryanke/articles/71491.aspx , but found that for reports of 300 pages it was taking about 2 minutes to render each page. When using RenderStream to render idividual pages, reports of about 20 pages printed without a problem, but for reports of 300 pages we recieved the follwoing error: "The stream cannot be found. The stream identifier that is provided to an operation cannot be located in the report server database." Is there some cache or something that we should be using Any ideas appreciated. -- Leah The ...Show All
