• Software Development for Windows Vista Handling events when hosting workflow in ASP.Net or a remote object

  I am looking to host workflow within ASP.Net and perhaps a remote object. In both cases it appears best practice to create the WorkflowRuntime once and reuse it for each call. However, having read Dino Espoito's article and looking at Matt Winkler's example I have some questions: In both cases their code registers with the WorkflowCompleted event on the WorkflowRuntime, but the handlers do not check that the workflow that has completed is the same one they started. Am I missing something here If the ASP.Net site was concurrently starting several workflows, how do you know which one you are handling the WorkflowCompleted event for Is it that because they use ManualWorkflowSchedulerService they only get an event raised that is relevant ...Show All

• Software Development for Windows Vista Updating My Application in the Vista Environment

  My application can check for updates over the internet. If an update is available, the application renames itself from appname.exe to appname2.exe and then downloads the new version. On the computer reboot, the new version runs and it SHOULD automatically delete the appname2.exe. This process ran fine in XP. In vista, under the admin account, the software renames and downloads without any problems and no vista prompts. However, when the computer is rebooted to the admin account, the appname2.exe is not delete at that time. ideas ...Show All

• Visual FoxPro multiple database locations headache

  Hi, I have an application which has a dev and testing environment. Each environment is on the same server, ie \\dataserver\application\dev\data and \\dataserver\application\test\data Unfortunately, I am having major problems with the DEV environment accessing the test (and vice-versa)!!!. Each table is opened with its full path name but the wrong table is opened. This is also true for remote views etc. If I rename the test (whilst running dev or vice versa) area then all is well. I have noticed that the header of the dbfs hold the absolute path to the database and not a relative on. I have even striped all absolute references to tables in the forms out. I am using VFP9 with SP1. Any help would be appreciated Regards ...Show All

• Visual C# Conditional Property?

  How can I make a class property available only if the class state meets certain criteria. For example, if I have a class "Dog" with properties "CroppedTail" and "TailLength".  I only want "TailLength" property to be visible to the user if "CroppedTail" is false. Thanks, Hammy Or just throw an exception in the TailLength property if CroppedTail is false. I really wouldn't go down the route of having a base Dog class and a subclass for dogs with tails... ...Show All

• Smart Device Development Questions about Smartphone's programming

  Hello, I am a novice at this and I have some basic questions (may be quite silly). Well: How many ways of building a new window/view are there in Windows Mobile 2005 I tried to do it creating a new Form and make Application .Run( new Form2 ()); where Form2 is the new created view. The trouble comes when, at the exit of Form2, the system shows an error: "An unhandled exception of type 'System.ArgumentException' occurred in System.Windows.Forms.dll Additional information: ArgumentException" Which are the tasks of Form2.cs and Form2.Designer.cs files I think that Form2.Designer.cs is the one who build the view, and the other one makes the main tasks. When VS 2005 deploys the appli ...Show All

• Visual Studio VS cannot locate a custom debug visualizer for a nested class

  I created a debug visualizer for a nested type (System.Collections.Specialized.NameObjectCollectionBase.KeysCollection) and when I try to use it in a VS project it cannot locate it. Meaning when I debug an application using this type, the debug visualizer icon doesn't appear for this type. I verifed the attribute that I have declared is correct (as far as the right types), I have this code in an assembly with another visualizer which can be found, and I have successfully debugged it using VisualizerDevelopmentHost. So my conclusion is that it has to be a problem with VS not being able to locate my debug visualizer through the DebuggerVisualizerAttribute that I have. Anyone have experience with this or know if it is possible to do Th ...Show All
