• Software Development for Windows Vista What is the rationale behind not having a static method to retrieve the current workflowruntime instance?

  After doing quite some work with windows workflow I am starting to feel that there is one thing that is coming back every time you work with the WF runtime and that is getting the current running instance of the WFruntime. What I just can’t grasp is why there is no static method on the workflowruntime class to retrieve the running instance. (or by name if you have multiple instances running) In every sample you look you see that not having this method makes the developers suffer and you need to make assumptions that are not always true. e.g. take a look, at the WebServiceInput activity and try to use it without the generated configuration when you publish the service. (name the configuration something else then “workflowRuntime”!) ...Show All

In the New Project dialog box, expand the Visual C++ node in the Product Types tree and then click Win32. Click on the Win32 Console Application template and then give your project a name and click OK. In the Win32 Application Wizard dialog box, make sure that Windows application is selected as the Application type and the ATL is not selected. Click the Finish button to generate the project."

• .NET Development Why does the designer omit certain events for some controls?

  I am using C# in VS2005 .NET2.0. I notice that in the form designer view certain controls, eg. numericUpDown and groupBox do not show certain events, eg. mouseMove, although the control class supports the events, and they can be set in code. Is there some reason for this, or have they just been missed out by mistake Most of these omissions are intentional. Controls inherit these events from the Control base class but they may not necessarily be functional. NumericUpDown.MouseMove for example is documented as "This event supports the .NET framework infrastructure and is not intended to be used directly from your code". The NumericUpDown control is really a container for a UpDownEdit and UpDownBut ...Show All

• 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

• .NET Development Possible to register a C# program to the R.O.T. for OLE automation?

  Hi all, I was wondering if it was possible to "register" your own created c# program for OLE automation This would be the equivalent of accessing something in Excel via OLE. Like: Dim ExcelApp As Object ExcelApp = System.Runtime.InteropServices.Marshal.GetActiveObject("Excel.Application") Edit: and just to clarify, I understand how the GetActiveObject works (by looking up the object in the Running Object Table). I guess I need to know if it is possible to register a program with the Running Object Table.

• Visual C++ Question about const_cast

  Here's round two of my silly questions.

  If at some point an item is removed from the system because it is no longer available...or no longer exists in the system, then any cart with the item still in it will cause an exception when they go to checkout. Is this a problem with the item deletion in MSCS internals What would be the recommended course of action Colin, thanks for the quick response :) This is actually breaking in the running of the total pipeline, which gets called directly after having run the basket pipeline, which calls those two components you recommended.

• Visual Basic How to raise event of parent class?

  If have a base class called 'eatSchedule' that declares an event, 'friend shared event TimeToEat(byval whatsToEat as String)' , and have a derived class 'lunchSchedule' that inherits the from 'eatSchedule', how do I raise the base class event If, in 'luchSchedule' I try type raiseevent, the 'TimeToEat' event isn't presented as an option. if I instantiate 'lunchSchedule' in another class, 'HelpMeDiet', I have the option of handling the event for 'lunchSchedule', I just can't seem to find a way to raise it. Thanks; Events are only raised by the class that implements them. The pattern to use here is to create a protected method in the base class: Protected Sub OnTimeToEat(ByVal whatsToEat As String) ' Raise event in here End ...Show All

• .NET Development 64-Bit OS Error: VFPOLEDB.1 Is Not Installed on Local Machine

  I need some help folks... I am getting the Infamous " provider not instaled on local machine" message for the VFPOLEDB Driver. 1.) It has NOTHING to do with what user I register it with (I've used them all, local and domain) 2.) The driver is most certainly there, and so are the registry entries. This error only occurs on 64-bit Operating Systems. Is there something different out there I have to do on a 64-bit OS. It says it registers correctly, the registry entries are there, and yet, I still get the error. I can install my VB.NET app on 32-Bit OS's all day long without error.

• Software Development for Windows Vista Show of Hands! Is WF by itself a viable approach to addressing a customer's workflow needs?

  Like many of us in the forum I am in the all too often unenviable position to influence my client's decisions. I currently have a lot of customers evaluating workflow, many for the 1st time. I personally have avoided building "custom" workflow solutions whenever possible as I have had success in the past implementing packaged workflow or BPM offerings, both Microsoft-based and less recently non-Microsoft-based. It's allowed me to focus my energies on building solutions and solving real business problems, not building infrastructure. Granted, there are customer situations that don't require or afford you the opportunity to buy a packaged solution to address a workflow/BPM need, but I would argue those are/should be the exception n ...Show All
