• Software Development for Windows Vista Newby questions

  Hi, digging around with Vista we came (after a lot of success with WPF things) to the point where we think about the WEB. We run a lot of web apps (ASPX). Most of them use Forms Authentication and profiles. Our idea is now to have those site support InfoCard. Before running into a totaly wrong way we try to ask here if our idea is totally stupid or not. The idea: When a user tries to enter a protected area we normaly bring up the .NET 2.0 Login control. This is pretty automatic - the user enters username / PWD and is redirected to the page after login. At the same page we offer a link to register - also using the "normal ASPX features" (Username, Email, PWD, Secret Question.....). On most sites we do an email verif ...Show All

• SQL Server SQL Server 2000 - SQL Server 2005

  A simply (hopefully!) question. I have a .bak file from a client who backed up there SQL Server 2000 database. Can I "restore" this into our SQL Server 2005 engine so that his database is created from scratch or do I need to first create his database and data schema, then do a restore Thanks, G You can restore a SQL 2000 backup to SQL 2005 using the [WITH MOVE] option. There may be additional issues related to logins, etc. I have included a number of articles that may be of help.

• Visual Studio Express Editions C# Studio & Express

  Can C# (Visual Studio) and C# (Express) be loaded in the same computer at the same time What about project sharing My current project is a freeware application with the source code released for free. I wrote in C# express purposly to allow my clients to modify the source without needing to purchase anything. However, I am wanting to purchase VS 2005 Pro to see if it has addtional optimizations to help improve the performance of my application, as well as port my application to mobile devices. My question is, what if I want to maintain the source in C# Express and just release my binary files compiled from VS Pro, can I just have two different project files and have them both share the same source Or w ...Show All

• Software Development for Windows Vista ActivityToolboxItem and event handlers

  Hi I have a number of custom activities that inherit from a common base class. This base class has no child activities, while the derived activities do. Furthermore, I generate the child activities using ActivityToolboxItem, this allows the users of my activity library to "fill in the blanks" at design time by adding additional activities to some of the branches. An example custom activity is: DerivedActivity : BaseActivity : SequenceActivity ListenActivity UserCompletionActivity : HEEA RequiresApprovalCheckActivity : IfElseActivity ManagerApprovalActivity : HEEA SkipActivity : HEEA This general pattern is repeated in all my ActivityToolboxItem classes, varying only the actual type of DerivedActivity. This appro ...Show All

• Windows Forms Mouse Location Problem

  Hello, I'm on a project, something like a mini-photoshop. I've done the basic stuff like opening the picture, drawing lines, using a pencil etc. well, I made a control that I see the position of the mouse with its X and Y coordinates as a MouseMove Event. But now I see that it just makes the program work really slow (I see its bad effect when I'm using a Pencil tool for drawing. It draws slower than it used to do when I didn't have the mouse coordinates as a mouse event.) Can you suggest something for this the code is: (visual c#) private void pictureBox1_MouseMove( object sender, MouseEventArgs e) {      form1pcm.toolStripTextBox1.Text = e.X.ToString();      form1p ...Show All

• SQL Server MDX "Filter" function Performance?

  There is about 3,000,000 records in the cube. And the members amount of [DIM FACT].[GOODS DESC] is almost 3 Million. I use the MDX as following: SELECT [Measures].[Price] ON 0, FILTER(NONEMPTY([DIM FACT].[GOODS DESC].MEMBERS), iif( InStr(1,[DIM FACT].[GOODS DESC].CurrentMember.NAME,"milk") <> 0, [DIM FACT].[GOODS DESC].currentmember,null)) on 1 FROM TestCube It costs about 10 Minutes . Is it too slow or it's normal thanks, Deepak Puri wrote: Only thing that I can think of is to take a different view of the problem - is there a certain set of keywords like "milk", which is established beforehand, or is this a completely ad-hoc query In the latter ...Show All

  I'm trying to use SendKeys on my form, so that when the user types a specific letter, it will send that letter to notepad or Word for them. I figured how how to indentify the letters ( 'ex.

• Visual Studio 2008 (Pre-release) Scrolling Windows Forms controls using ScrollViewer

  Hello! I have a problem scrolling a hosted Windows Forms control using a WPF ScrollViewer. The problem is that the WinForms control is not clipped to the contents of the ScrollViewer, but it overflows it, covering both the scrollbars, and also other controls around it.

They want quality of apps up so they are selective. To those who don’t know what the Community Developer Program is, it is a program that gives access to additional Xbox live user data, they have come up with thinks like Xbox 360 blogs and game score charts.
