• Visual C# Is it possible to add to a system class?

  For example could i add a method to System.Array I know i could create a new class that inherits but would be nice to just tag it onto the system class! Thanks Not in C# 2.0 or less. In C# 3.0 you can create what they call "Extension methods" that essentially add a method to a class. See http://www.interact-sw.co.uk/iangblog/2005/09/26/extensionmethods for more details. ...Show All

• Software Development for Windows Vista Notifying a Distributed Workflow of State Changes

  Picture this scenario: You have a central workflow, hosted however you see fit (WCF, Web Services, Remoting, whatever) and you have three different Windows Forms applications consuming this workflow. Each application can cause the workflow to change state, but I also want each application to listen for state changes to the workflow . My current train of thought involves linking the Windows Forms applications in a peer network, and whenever one peer changes the state of the workflow, the other peers are notified via service messages. The problem I'm having is that the peer network isn't functioning properly - using PNRP the peers don't detect each other reliably (sometimes they do, sometimes they don't). So, I'm wondering: do I take t ...Show All

• Visual Studio Express Editions Painting into an image box

  Hi I know you can draw lines and things into a picture box with picturebox.CreateGraphics.DrawLine(Pens.Green, 5, 5, 6, 6)   etc   But why will it not work with variables in place of the 5, 5, 6, 6 Is there a way of painting a custom colour instead of a pen colour     Is there a better thing to use that allows me to just change pixel coordinate colours as it is easier to imagine and write code for, this is confusing to me. Ah yes! That works! But... it only paints into roughly half the picture box... And it has slightly different shades of blue and green - how can this be I only chose blue and green! The drawing disappears if I switch to a diff ...Show All

• Visual Basic Trouble Including Image Files with a Program Distribution through the Resources folder

  I'm having some trouble including three image files I need via the Resources folder. In my Resources view, the only 'Persistence' options are 'Linked at compile time' and 'Embedded in .resx' - trying either one, I get a System.ArgumentException when I try to load the images from "Resources\image.gif" - I have three other images that load perfectly find from "Resources\otherimage.gif" - what am I doing wrong Hi, Try putting all other files in the BIN folder of your project/solution as i've been told by my lecturer, that is the 1st place the Visual Studio IDE-compiler looks for files. Try also ( if you wish ), files in the main folder of your project/solution. You woul ...Show All

• Visual Studio Express Editions unhandled exception message

  is there a way to aquire the message that the details of the exception makes. Not the exception.message property i am talking about the part that says "arguementexception was unhandled" In addition, there is a global routine already in place that will handle any exceptions which haven't been handled: Select MyProject, Application Tab, Application Events, select MyApplicationEvents and add code to the MyApplication_UnhandledException() event. You can also prevent the application from closing after an unhandled exception. ...Show All

• .NET Development XmlValidatingReader does not give any validation error

  Hi I am using XmlValidatingReader to validate my XML with schema. There is a particular validation error that does not appear when I use the XMLValidatingReader, but it is  shown when I try with XML SPY. I am sure XML spy is right in this particular case as I can see manually that the schema does'nt allow a particular element and it appears in the XML document. Is this a bug in microsoft If you need more details, please let me know.

• Visual Studio VSTA SDK

• Visual Studio Team System Schema Compa Using a project as Target Schema

  Hello, I noticed that a project can be used as the Target Schema in a schema compare. Is there anyway to update the project with what is currently in the source database The script that is generated is SQL meant to be run on a database and the 'Write Updates' button is greyed out. Are there any plans to implement the ability to directly update the code of the project via the Schema Compare It could also be useful to be able to compare project to project and then update accordingly. I was just curious if anyone else had similar thoughts or answers. Thanks, - Grant Thank you for the feedback:-) and I do hear you. We have heard this alot from customer with the recent CTP and at Tech Ed. We trying ...Show All

• Windows Forms Making a typed resource file public

  Hi! I made this question before during the beta period but I'm coming back just in case something changed after the final release of vs2005. Is there any way for a typed resources class to be generated as public so that they are accessible by other projects expect the project containing it. The ResXFileCodeGenerator custom tool generates this class as friend. The only work around I found is to clear the custom tool property from the resource file to executer the resgen.exe manually. Isn't there any other more elegant way Hi, I have fixed the tool, it should be working fine in VB.Net projects by now. Please let me know if it's still broken. Sorry for the trouble.

• Visual C++ Visual Express to Standard Edition.

  Visual Express to Standard Edition. I downloaded Express to evaluate C++ 2005. A problem with FileStream was resolved by opening and closing the stream for each action to my database. On a large report doing random reads endless opens and closes might be a problem. On the Standard Edition can I use MFC CFile IO instead of FileStream using the new syntax (i.e. gcnew etc.). Another issue of concern is debugging. On versions 2003 and 2005 express everything of interest to a malfunctioning function is out of scope - including the argument to that function. Has this been addressed on the 2005 standard edition Re: Visual Express to Standard Edition - resolved. All problems relating to FileStream have been resolve ...Show All
