• Visual Studio Feature request: Referencing Code Samples

  I often add example-code to the code comments showing how to use a certain function. The problem is that if I refactor the code, the example will be incorrect and there is no way of checking the example code with the compiler. Usually what I do is creating a bunch of methods that uses the functionalities and copy/paste that over into the summaries. This is a pretty stupid way of doing it though (because of the human factor involved). So this is what I propose: 1. Create a code sample file that compiles, and has parts of the code marked by regions: public void Example1() { #region Example1 myObject = new myObject (); myObject.Invoke(); #endregion } 2. Reference the region in the code summary: /// <example>Create a ...Show All

• Software Development for Windows Vista Trouble with the ManualScheduler service and delays

  Hi, so I have this workflow I've been working on for a few months. It's made of a few parralel branches (5), which look like this : picture The whole thing is hosted in an ASP.NET webservice (in its global.asax file). Along with the ManualScheduler service (with UseActiveTimers on), I'm running a persistence, tracking and data exchange service. And while I thought I did everything right (according to other posts here), expired delays still don't cause the workflow to fire up, so I always have to wait for the runtime to do something (ie : instaciate another workflow, send an event to a workflow, etc...) before anything happens... (this, I assume is what it is supposed to do without UseActiveTimers activated). I really hope ...Show All

• Visual Studio 2008 (Pre-release) IIS with wshttpbinding VS windows service with netftpbinding

  Which config would you recomend for a server I think that for a server it should be better the IIS (threads perhaps are used better than using "the iis inside framework 3.0". What do you think I have services hosted both Windows Service and IIS and both work fine. Hosting in IIS provides the following benefits 1. Automatic activation of the Service and no need to write hosting code 2. You can deploy Source or binary (Just like aspx) 3. Health monitor, automatic process recyling and others.... ...Show All

• Windows Forms How to record screen?

  Hi I wish to record the desktop/screen/particular window. The user clicks record button and recording starts till user clicks stop button. How do I access different windows from c#.net The window can be a webcam window of skype/yahoo or a windows media player playing a clip or the desktop !! Thanks Aseem Chiplonkar You could use "Windows Media Encoder SDK" to do that. This is a free tool offered by Microsoft. There is an executable in this package that will let you capture the screen when you wish to start and stop as a "Windows Media Video" file. There are plenty of other places that you can find tools to do the same thing... such as "Lead Tools". ...Show All

• Visual Studio Express Editions Can I use VBE 2005 classes in Excel 2003 VBA code?

• Windows Forms WebBrowser and BindToMoniker

  Hi, Recently, We've begun upgrading certain components of our project. One of those components was the ActiveX Web-Browsing control who was dumped in favor of the native .NET version of System.Windows.Forms.WebBrowser. This version, however, Does not seem to expose the document as an object, as its ActiveX version did. We use those controls to display Word documents as hosted in the web-browser itself. For this reason, We need access to the document object. To get around this problem, I was using BindToMoniker with the navigated file\url to get Word's document back again ( DownloadComplete event with the AX browser, DocumentComplete event with the new browser). This, However, Seems to not always be successful. Quite often BindToMo ...Show All
