• Windows Forms Check if Component is Unique

  How can I give a component the functionality to check itselfe if there is the same ComponentType on a Form or UserControl Try this: Declare one of the methods above in your class, in the load event of a new object of your Component/UserControl, check if the control will be unique or not, if not, through an Exception with a descriptive method. I think that for most user controls and components, Load event will be fired at design time and if the constructor throws an exception, a message will be displayed! The constructor is not the right place to do this! I tried the following in a user control in the load event and it works fine (it displays a message wi ...Show All

• Visual Studio 2008 (Pre-release) Programmatic Mex Binding

  Is it possible to expose a Mex binding programmatically In order to enable Mex the only way I can see is to use Config file settings and while this works in most siutations I have an Interop Scenario where using Config files is quite a bit of a pain. Is there a way to have a host expose these endpoints I can't seem to find the Binding class to use. Also, in this same interop app I can't seem to get Mex to work even with the .Config file. < xml version = " 1.0 " encoding = " utf-8 " > < configuration > < system.serviceModel > < services > < service behaviorConfiguration = " WcfFoxServiceBehaviors " name = " WcfFoxServ ...Show All

• SQL Server sp_cycle_agent_errorlog fails/SSMS recycle Agent log fails

  Hi, The sp_cycle_agent_errorlog stored procedure fails on our primary SQL Server 2005 server; the SSMS context menu option (right click Error Logs under SQL Server Agent in object explorer) to recycle the agent log also fails.

• Software Development for Windows Vista Host a statemachine and have multiple client applications receive events

  Hello, I would like to have an application hosting a number of state machine workflows and have a number of client applications post events to update the workflow and receive the events to notify the client applications of these updates. Is this possible and if so can anyone point me in the direction of a sample. TIA Trevor.

• SQL Server Package variables

  Couldn't quite find the answer I was looking for via a forum search. I have 9 packages that are currently called by a master package - all child packages take a datetim e variable from the master package which is subsequently used in the child processes.

However we will be wishing to automate the package execution at some point and want to know the best way to run the package(s) on an automated basis and have the data variable supplied to the master package. What would be the best way to do this Presently we have a variable called MasterPackage ...Show All
