• SQL Server Programatically create and configure a FlatFileConnectionManager

  I am writing some C# code that builds a package programatically. the package contains a flat file connection manager. I have referenced Microsoft.SqlServer.Dts.Runtime.Wrapper in order that I can use the ConnectionManagerFlatFileClass class. Here is some of my code: Package p = New package(); ConnectionManager sourceCM = p.Connections.Add("FLATFILE"); sourceCM.Name = "some-name"; ConnectionManagerFlatFileClass cmffc = sourceCM.InnerObject()   I get a compilation error on the last line saying I cannot implicitly cast as ConnectionManagerFlatFileClass . Fair enough, so I change the last line of code to: ConnectionManagerFlatFileClass cmffc = ( ConnectionManagerFlatFileClass )sourceCM.InnerObject() ...Show All

• Software Development for Windows Vista "Tracking workflows which are already tracked" - Problem

  Following screnario: I have business objects of the type Order and OrderItem. For each of these a workflow is started. I use the SqlTrackingService, so running workflows get written to the db, and I am able to track them with the WorkflowMonitor (included in the Windows SDK I think). If such an Order- or OrderItemWofklow gets aborted or canceled the chance of restarting the workflow with the same objects is still present. The only problem is that the Guid of the started workflows was chosen by myself to be the same as the Order / OrderItems. But if a workflow gets aborted, or canceled, it is still in the tracking database. And when I restart the workflow for the same Order / OrderItem (which is possible by the design of the applic ...Show All

• .NET Development Creating a generic stack at runtime using reflection

  Hi, I want to be able to create a generic stack and push object onto it at runtime. I have the following code: type t = Type .GetType(nameOfType); Type type = typeof ( Stack <>); Type [] args = { t }; Type constructed = type.MakeGenericType(args); object stack = Activator .CreateInstance(constructed); This works but I cannot cast the object to a generic stack in order to Push something onto the stack. The only way to do it is to use InvokeMember on the stack but that is slow and cumbersome.. Any suggestions Best regards Alex Lehmberg You can't. You cannot cast it to Stack<T> because this is not a type by itself and you canno ...Show All

Inititally through their own command buttons, then by checkboxes and a single command button, however I could never get the thing to work.

• .NET Development Missing DWMAPI.dll causes problem with COM interop in c#

  I have recently installed IE7, and am now experiencing a problem with COM interop in one of my c# projects. It seems that there is a dependency on a dll called DWMAPI.dll from the COM dll. I have read a bunch of posts about similar problems, and it seems this dll comes with Vista, but is missing on XP machines. For some reason, installing IE7 makes it become a dependency for things like .NET interop. The only solution I have been able to find in the forums and posts is to uninstall IE7. Microsoft has not yet posted anything that I could find in regards to this issue. Does anyone know something I don't Any help is greatly appreciated. Thanks, Dan Well, as long as you know what's going on. There's ...Show All

• .NET Development Some useful classes in .NET

  I have ideas about some useful classes to be created in future versions of .NET. I don't know where to post it so I post it here. Here they are: 1) Generic hashtable (it's useful when you have objects of one type in it, it helps to avoid many typecasts) 2) Array with arbitary intexes(including negative) 3) Math.Max(params ...) - Max function for many variables (int. arrays of variables) There is not GenericHashtable like thing but a Dictionary class which is used to store objects of same type with a unique ID, the other Generic Colleciton is List<T> in contrast to Dictionary there is not Unique key used in this collection type. The Above classes are Present in .Net 2.0 not the previous version! Best R ...Show All
