• .NET Development Dictionary versus SortedDictionary (Generics)

  Is it true that the Generic SortedDictionary does not use hashing (like Generic Dictionary does), but instead uses vanilla comparisons of keys (i.e. binary search, logn time complexity) I ask, because a compatriot insists that both generic containers (Dictionary, SortedDictionary) use hashing.  I think he is mistaken. hi, Both are implemented in the System.Collections.Generic . Details follows :  Dictionary Generic Class and SortedDictionary Generic Class . ...Show All

• Visual Studio Express Editions Creat Thumbnail, and View Image on Click

  I would like to create a button or other object that would create a thumbnail of the image it represents. When someone clicks on it, I would like the larger image to display in a PictureBox on my form. I would appreciate any help anyone can give me, as I have not been able to get any of this to work... Thanks, i believe picturebox4_Click signature should be.... instead of PaintEventArgs, try EventArgs in regards for placing the other line of code I posted earlier, place that when the user clicks on the control when you wish to enlarge that picture and show it into the picturebox control :-) Either on a button click such as "enlarge image" or some other picturebox control where you are display ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Object cache vs. GameComponentCollection

  Can anyone tell if the GameComponentCollection is designed to simplify game object cache requirements I noticed that the space wars example seems to override this with screen.Render(). If it is supposed to, are there any forseeable performance impications I don't believe so. GameComponentCollection is just a collection of GameComponent classes - it has no special functionality of game object or resource caching. The reason you saw the screen.Render() override is because space wars uses a component to swap in different game "screens" - the main menu, the play space, etc. It doesn't really do any caching in itself - the screen component seems to act as a container for the rendering code, making it easier to swap in and ou ...Show All

• Visual Studio Team System Hide projects from users who can't do anything in them?

  We have dozens of team projects in our TFS server for a lot of developers. Is there a way to hide the ones from the users who can't do anything in these projects Is this the permission that controls this < permission name =" GENERIC_READ " class =" PROJECT " allow =" true " /> The [SERVER]\Team Foundation Valid Users group has this permission and every user belongs to this group directly or indirectly by default. Right now we do not hide projects that the user does not have permission to. We are tracking this as a product idea for the next version of the product. Thanks, Jeff McKune ...Show All

  At first, I enjoyed the new webbrowser control but then I noticed that the args provided by the events NewWindow3 and BeforeNavigate of the axWebBrowser had not been implemented in the new control.
