• Internet Explorer Development Image Pop Ups

  I have a large image of a land development map. I would like to create hotspots on it on each lot, and when the user mouses over, have a Tool Tip style pop-up appear with the owner's information. I have found some third-party solutions that all rely on mousing over a link, or some other page element. That's not what I need. I would like to define hotspots WITHIN a large image, and then when moused over, the info appears. I've already implemented this using traditional image hotspots to launch a seperate window when clicked, but that's clunky. I can implement this using AutoDesk's .DXF IE plugin, but it doesn't work on non-IE browsers and I don't want the end user to need to download it if they're suspicious of such things. T ...Show All

• Software Development for Windows Vista Workflows and returning data

  I have built a workflow which in the end gets an XML document. That document holds the information that has to be used by the presentation layer. The workflow is a part of a Workflow Library. How can I send that information to the presentation layer, I am not able to access any variable declared in the workflow Thanks in advance, Marko Vuksanovic. just after instance.Start(), add : waitHandle.WaitOne(); and set the waitHandle as a field of your form ; To make the code safer, I would have done everything in InitializeWorkflow() (including starting the instance) ; and only the dataset would have been a data member.

• Game Technologies: DirectX, XNA, XACT, etc. Sprite Collision Detection

  I have a 2D game which I wrote some simple collision detection for, which works like the bounding box example. It detects collisions very well, the problem I am having is moving the objects back so that they are not overlapping. They move 10 pixels a move, so when they collide, they overlap. I want to be able to detect a collision, and move the object that caused the collision back to the point just before they intercept, i.e. not the last position, but somewhere inbetween the last move and this one where the two do not intersect. I hope that makes sense. S Hughes (Clarity Consulting www.claritycon.com) Shughes wrote: 10 pixels maybe too fast, but I wanted my character to move reasonably quickly ...Show All

• Visual Studio Team System TFS Integration adapters

  There's mention in the Team Foundation Server Extensibility documentation of "integration adapters" with an example of a help desk application that synchronizes help desk requests are synchronized with work items. But, that's about as much detail on "integration adapters" that I could find in the extensibility documentation. I recall mention that one benefit of the TFS architecture is that a SQL Server instance is available for use to store extension-/application-specific data. Is there a recommended architecture and process for this type of integration Specifically, if data-centric extensions or linked applications are expected to use the TFS SQL Server instance is there a client-side property or method for ge ...Show All

• Visual Studio Express Editions Won't let me save

  After solving my first problem with visual basic I hve ran into another. It wont let me save any project, if I try I get "An Error Occured Saving The Project File 'project4.vbproj'." Any more ideas How are you trying to save it. When a start a serious project a create the project from a template and exit. This brings up a prompt asking me is I want to save it or discard it. Since I want to save it, I select Save and it prompts me for where to save it. There's glitch here. If I haven't created a directory I can create one. But it never seems to recognize the newly created directory so I cancel the save but I still have the project and I exit again and go through the same process only no ...Show All

• SQL Server Running Custom Business Logic during synchronization

  I have a merge replication topology that allows some subscribers (clients) to retreive a number for certain columns (ie invoice number, order number, etc). I have implemented a custom business logic handler to check for inserts from the subscriber and before updating the server, I call a stored proc on the server to generate a new number. I update the data set and call ActionOnDataChange.AcceptCustomData. This works great for the publication db but I am trying to get this new number back into the subscription db. I am using web synchronization so I really don't have a connection back to the subscriber database. Any Ideas I was thinking about keeping track of the updates myself and build a sql string and somehow get that back to the s ...Show All

  Hi, I am encountering some strange behaviour implementing a custom username/password authenticator. My custom authenticator wraps the default WindowsUserNameSecurityTokenAuthenticator, but resolves the username the user provides into a domain account using some custom logic. So my custom authenticator looks something like: class MyUserNameTokenAuthenticator : WindowsUserNameSecurityTokenAuthenticator { protected string ResolveUserName(string userName) { // My custom logic here ... } protected override ReadOnlyCollection<IAuthorizationPolicy> ValidateUserNamePasswordCore(string userName, string password) { string resolvedUserName = ResolveUserName(userName); return base.ValidateUserNamePasswordCo ...Show All
