• Software Development for Windows Vista Is it possible to exchange a running workflow for a different workflow?

  Hello everybody! Let me explain my situation: I created an ASP.NET web-application which is based on a state machine workflow. When one of our customers is not satisfied with the default implementation of the workflow, I need to exchange the running workflow with a different workflow. The changes to the workflow are minimal, but they are required for the customer. Is it possible to exchange a workflow for a different one, even if it is already running and there are persisted workflow instances in the database If not, what can I do to accomplish this Thank you for your quick answer! I read your post but now I've got an other question: How do I accomplish that my ASP.NET web-applicati ...Show All

• Visual Studio Tools for Office Getting "Cannot add chart" when trying to add a chart to an Excel workbook

  Hi, When I try to add a new Chart object to my work book I am getting this message: "Cannot add chart. Excel might be in a mode that prevents charts from being added." Can someone tell me what is this Thanks, No idea to which "pane" you're referring, but try taking it out of the separate thread and see if that makes any difference. When you run into a problem that's happening in one place, only, that's how you start trouble-shooting: take away everything that's different from other projects, then put these things back one at a time until you isolate the cause. One other possibility is that the Excel workbook file, itself, has been damaged. I don't know how likely this is, but try ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Managed C# performance loss.

  I caught some people quoting managed performance loss at only 2% (over unmanaged). I am just curious how accurate that assessment is. Last time I was looking into it, DX programmers were quoting 90% of managed performance as a BEST case scenario. (usually much lower) If the margin has grown so low, is there any large scale games developed using C# Remmie wrote: ...remember that fast software is mostly a matter of good software design :) Ain't it the truth... ...Show All

• Visual Basic Intercepting a CD Tray Open

  I know how to open a CD tray programatically, but is there anyway to determine when a user has pressed the button and then either allow or disallow the tray from opening, or is it strictly a hardware issue Thanks in advance. not quite. It really is hardware based to be honest. Well, actually you could do this but it would require some hooks into the OS/kernel and listen for those events then some how cancel the event but really not worth it as it requires alot of calls to Win32 ...Show All

• Windows Forms MTAThread and AutoComplete

  I need to use the WaitHandle.WaitAll and TextBox.AutoCompleteMode. The problem is that the first requires MTA and the latter STA . Is there any way around this rich Hi Rich, Based on my knowledge, to invoke a method on UI Control on the main thread from another thread, we recommend you use the Control.Invoke which is implemented by SendMessage. Due to the Winform is not thread safe, we do not recommend you put it into MTA thread. Also .NET do have more payload than Win32, because if the .NET code underlyingly call the unmanaged code, it need P/invoke or COM interop marshalling(if .NET code call an unmanaged COM, we also need marshaller). Also for .NET code to run, the .NET runtime need to JIT the MSIL to nat ...Show All
