• Visual Basic Memory usage - events

  I recently answered a question at VBCity about a memory leakage with VB.Net: "I am creating a class with an Event, then I instantiate the class and dispose of it. VB seems to be wasting 16 bytes each time. " I did some research, and found something really interisting. A small VB.Net application to test this showed that the memory usage slowly increases over time. The object never gets collected. A C# test worked as expected (memory usage increases the 1st time an object is created, and then it stays the same). When I investigated the CLR code for this, I noticed why: C#'s ctor function only created the object, while VB's did the following: IL_0001: call instance void [mscorlib]System.Object::.ctor() IL ...Show All

• SQL Server SQLServerAgent Rights

  Hi, I have a problem that concerns the abillity to specify rights to edit and run one or more jobs in SQL Server 2005. What a want to accomplish is to let one or more users edit a job and run it. As far as i can see that isn't possible since the user that want's to edit the job has to own the job, and only users can own a job and in that case more than one user won't be able to run the job. It's a catch 22! Does anyone have any suggestions regards An interesting article here ...Show All

• .NET Development Programmatically change UpdateMethod of ObjectDataSource

  I want to change the UpdateMethod of an ODS. I've tried changing it but it keeps going to the method initially defined. The parameters are the same between the two methods. The docs indicate that you can Set the property and you don't get a compile error. Any thoughts From the code above, shouldn't it be ObjectDataSource2.UpdateMethod = "UpdateContact" Have you tried placing a breakpoint on the CustomerDS.UpdateMethod = "UpdateContact" line to make sure it is executed as expected Charles ...Show All

• Visual Basic Writing a pixel.

  Hello All, In the days of VB6 one could use Pset to write a pixel onto the screen. It appears that VB2005 has considered this uneccessary and ignored it instead. The help suggests drawing an ellipse of size 1 pixel (isn't this like using a jackhammer to crack a nut ) so I did with this sample code: Dim myStyle As New Pen ( MyColour , 1) gr . DrawEllipse ( myStyle , Xpos , Ypos , 1 , 1 ) Sometimes I get my single pixel, sometimes I get a vertical line of 1x2 pixels - depending on the values of Xpos and Ypos. Is there a reliable way to paint one pixel As an aside - does anyone know why MS abandoned the Pset type construct - are Pixels not worthy in VB2005 All the best. ...Show All

  Hello! I would like to use the Microsoft.ReportDesigner.Design.ExpressionEditor.EditValue(IServiceProvider provider, object value) method. My problem is that at the moment I don't know what properties/fields the object value has to have so that the Expression Editor recognizes that it is associated with a RptDataSet when I click on 'Fields'. I've spent a couple of hours trying to guess the properties/fields without success. Can anybody please give me a pointer Many thanks!

• Visual C++ C++ or Visual Basic for Windows Applications?

  I'm new to .NET, Visual Basic, Visual C++, etc. and I'm interested in creating Windows Applications. Which would be better to use, Visual Basic, or Visual C++ (And what about C# ) Thanks. I personally have just switched over to C++, and I have been using Visual Basic.NET for awhile, and I found it a lot easier to learn to program using Visual Basic, but I want more control now over how the program operates so I just switched a few days ago. But Visual Basic is much easier to both start with for learning and also for faster application development as far as I am concerned, unless there are more complex custom procedures required which in that case would be easier.

• Game Technologies: DirectX, XNA, XACT, etc. Please Add Non-Generic DrawUserPrimitives and DrawIndexedUserPrimitives methods.

  I posted this request in the Suggestion tool as well. Btw- where is the link to actually view the contents of the Bug reports, and Suggestions You'd think that would be handy from the connect.microsoft.com site, but I can't find it. Add the method: Device.DrawUserPrimitives(Type vertexType, PrimitiveType type, int count, Array vertexData); and a similar non-generic method for Indexed primitives. I have a rendering system that captures rendering calls, and retains the call information. Later on, it sorts all of the calls in order to minimize state changes before execution. This is a very commen scenario. IT IS VERY DIFFICULT to call generic methods (in a generic fashion) when you only know the vertex type, and have a un-typed array. For ...Show All
