• .NET Development Web services middleware, guaranteed delivery - real world usage

  I am attempting to investigate as part of a project, available solutions in industry that can act as message middleware applications to ensure guaranteed web service delivery. To explain further, a web service typically just sends requests to a server often displaying the results on a 'thin client'. When used instead of a messaging type system (e.g. MSMQ), web services can also provide an effective messaging solution. However, when connectivity is unavailable, web services fall over here as messages are not queued so delivery is not guaranteed. To get around this problem, in a solution I developed, I wrote a small middleware application that ...Show All

• .NET Development system start-up detection

  Hi , I have an application that runs in system tray with a notify Icon. It can also be launched from an exe in desktop as well as Program menu.

• Windows Forms Treeview AfterLabelEdit Problem

  In summary, the problem is when you add a node to the treeview and then reload the treeview in the AfterLabelEdit event.  It adds the node in 2 places, even though I am reloading the data from the database to load the treeview.  If you reload the treeview outside of the AfterLabelEdit event, the treeview loads fine. I have submitted this bug to MS and they are taking their sweet time on it.  I have also had another post concerning this issue with adding nodes to the treeview in the AfterLabelEdit event and then reloading/refreshing the tree in the AfterLabelEdit event as well. What I need is for someone else to confirm t ...Show All

• Visual Studio Team System Access Denied: User needs the UseSystem global permission

  Sorry this is a little long. I wanted to provide as much detail as possible, so someone can tell me where I am being stupid. I'm trying to set up an Active Directory group who can create Team Projects.  This would allow me to manage who can create Team Projects from one place. I am running TFS Beta3 and VS2005 RC in a dual server configuration. I created a AD group, called TFS Project Users. I added a generic user, Developer2, to this group. I created a Team Foundation Server group called Team Project Creators. This group is automatically added to the [SERVER]\Team Foundation Valid Users group when you create it.

• Smart Device Development Console application in 'Running Programs' control panel?

  Hi, When I create a Forms application for Compact Framework, it appears in the Settings->Memory->Running Programs control panel. However, when I create a console application, it does not. Is there a way I can 'register' my application in this way, to indicate if it is still running, and if needed, to kill it No, you can not. Your application needs to have a window for that. Consider creating another application to kill/start/pause your "service" application. ...Show All
