• Smart Device Development Update with a Guid ID

  customerID =Guid.Equals(lvCustomers.FocusedItem.Text); I wan to make a updatate statment using a Guid.Updating with a int works great but not when the data is a Guid. Any suggestyions Have a nice day. Guid.Equals isn't a static function, is it It's an instance method I thought ...   either way, you likely need to cast the text value as a Guid before comparing in order to achieve reliable results.   you're setting your customerID equal to the bool result of the Equals method ...   maybe you want:   bool idsMatch = customerID.Equals((Guid)lvCustomers.FocusedItem.Text); ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 3D picking with the mouse combined with a moving camera...

  Hi all, I'll get right to the point. My camera is defined using the following code... cameraworld = Matrix .CreateTranslation(xplane, yplane, 0) * Matrix .CreateScale(zoom) * Matrix .CreateRotationZ(angle); view = cameraworld * Matrix .CreateLookAt( new Vector3 (0, 0, 100), Vector3 .Zero, Vector3 .Up); projection = Matrix .CreatePerspectiveFieldOfView( MathHelper .ToRadians(45), ( float )graphics.GraphicsDevice.Viewport.Width / ( float )graphics.GraphicsDevice.Viewport.Height,1.0f, 1000f); effect.View = view; effect.Projection = projection; I've also got code to allow me to place objects in the game world, after unprojecting the mouse points and finding the point of intersection with my XY plane.

• Visual Studio 2008 (Pre-release) Weird image loading/saving dpi-related problem

  Hello,   I am trying to generate thumbnails from files located in certain folder and save those thumbnails into other folder as jpegs. Everything works nicely and rather fast, but I bumped into one strange issue.   Most of my jpegs have internally set DpiX=DpiY=96 - and these behave nicely.   Problem is that some images have DpiX=DpiY=144 (or some other values). PixelWidth and PixelHeight are correct in all these images, but Width and Height properties are not - they are taking into account dpi values.   Getting thumbnails of these images is not an issue - I am using DecodePixelWidth or DecodePixesHeight on BitmapImage object to get them and it works very well. Unfortunately, when ...Show All

• Office Live Development Web site user authentication and Data Sharing

  I'm building a workspace application for my client base to use in their own Office Live sites. It holds extra data for my clients' projects that are associated with particular opportunities. For example, the workspace includes XML parts lists and JPG design images, each referencing an Opportunity ID in the WebBCM. This works nicely in-situ - I have a Dashboard for this workspace that allows me to select the relevant Opportunity and show the associated design images and renders the XML parts list through XLST. What I'd now like to do though, is for my clients to be able to share the images with each customer. The customer should only be able to see the images that are relevant to them. I may want to add other data from other lists too ...Show All

• SQL Server Denying access to a whole dimension

  In AS2K dimension security I could deny access to a whole dimension using the 'Fully Restricted' setting on a role. In AS2005 I can't see how to do the same thing - the only thing I can do is to deny access to every member on every attribute but even then I still see the dimension name in the metadata. BOL suggests it is possible but its descriptions of the UI must have been written before RTM and don't bear much resemblence to the current situation; I've also had a go at setting some of the properties on the permissions object in the XMLA definition of my cube but they don't work either. Is this feature still available If not, can we have it back Chris Hi Radim, I have no idea whether Connect is closed to new users - it seems ...Show All

• .NET Development HowTo: Forms Authentication with WebService for database access

  I have an ASP.NET 2.0 application that uses a WebService for all database access (SQL Server). Now I have to implement a login page that uses Forms Authentication. I just did a test application, without a web service, that uses the Login control and all the 2.0 built in functionality and it works perfectly out of the box. Now I need to do the same thing using the web service, including role management. How much of the new functionality will I be able to use To do the actual authentication, is there an API to access the SQL Server aspnetdb database How do I handle roles Can I build the GenericPrincipal on the web service and pass it back to the application Are there any examples of doing this Any id ...Show All

• Software Development for Windows Vista How DirectShow pins negotiation and connection process?

  In both pull and push transport methods, how output pin from upper stream (source) filter and input pin from downstream (destination) filter negotiation with each other for connection Would someone please explain for me I have idea that have to deal with the AM_MEDIA_TYPE structure but I configured both upper stream and downstream filters have same value for “majortype” and “subtype” and they still not connect together. What else should I look for Thank you in advance for your time. Look also at the allocator negociation & decide buffer size.

• Software Development for Windows Vista About GetClientRect in AERO

  I use GetClientRect function to retrive the coordinates of a window's client area and then draw a bitmap into client area in WM_PAINT callback function. But when AERO is enabled and the minimized main window is restoring, the bitmap is presented before the main window being restored. It is no problem when AERO is disabled. There is a slow animation when a window being restored in AERO. How to detect the animation is over Or, should I try another way Don't call SetWindowPos() in WM_PAINT, that's asking for recursion death. The *only* thing applications should do on WM_PAINT is BeginPaint()/paint to ps.rcPaint/EndPaint(). ...Show All

• Visual Basic Can you mame your own attributes, or whatever they're called?

  I'm new to VB, and I was wondering, when you click and drag a button or something on to a form, and it has properties or attributes, or whatever, like button size, what it says, etc. Can you make your own field for something like that Thanks. A control such as a button is a class. Some classes are inheritable which means you can use these as the basis of a new control inheriting all there functionality and then adding to it. For these you can add or modify the existing class functionality. For these you can add your own properties, methods and you could create you own attributes but for what you talking about its probably more likely to be methods and properties you'll want to add. I'd probably loo ...Show All

• SQL Server How to deal with User!UserID in Data-Driven Subscriptions

  First a bit of background. We use the Windows-logon to authenticate en identify the user. With this logon we check within most of our reports what a user is allowed to see. Depending his level or geographical location he is allowed to run reports on one to all sites. He can selects the sites from a Multiple Select box. This works fine. Now, we want to use data-driven subscriptions, I understand why we can't use this parameter, but how do you people deal with this kind of configurations. I would prefer not to 'double' the reports in a normal and a subsciption version ..... Markus, I've send a mail to Brian and hope to hear from him. I'm using the UserId as a parameter in a query that resu ...Show All
