• Audio and Video Development XPath Syntax - which is best?

  state:actioned()=true() state:actioned()=true state:actioned()=1 state:actioned() Are all of those valid and one in the same Depending on which document or sample I'm looking at I see all flavors. The second one ( focused()=true ) is an error, since true by itself is undefined. The rest are equivalent, but yeah, having no RHS is less typing. Note that any non-empty string is converted to true, so you could have focused()='0' or focused()='false' or even focused()='Jack Sparrow' and they would all be equivalent to true() . Only focused()=0 or focused()=false() or focused()='' or not(focused()) are really false. ...Show All

• Windows Forms Need to do a context Menu on the design surface

  I've been sifting through the documentation for several hours now and need some help. I have successfully impltemented a forms designer. newDesignSurface.BeginLoad( typeof ( Form )); I'm able to move and size my controls with no problem. Now I want the same functionality that is in Visual Studio when you right click but I can't find what services are needed to do the following.

• Visual Studio 2008 (Pre-release) Resources, Templates and Styles

  I think there must be some fundamental that I'm not understanding correctly. Why are Style Resources with an explicit TargetType key not utilised inside DataTemplates This does not seem intuitive to me as DataTemplates with an explicit DataType key are utilised. See the following example: < Window xmlns = " http://schemas.microsoft.com/winfx/2006/xaml/presentation " xmlns:x = " http://schemas.microsoft.com/winfx/2006/xaml " xmlns:sys = " clr-namespace:System;assembly=mscorlib " > < Window.Resources > < Style TargetType = " {x:Type TextBlock} " > < Setter Property = " Background " Value = " Cyan " /> </ Style > < DataTemplate DataType = " {x:Type sys:Int32} " > ...Show All

• Visual Studio Team System Question with VS 2005 and TFS

  Hello everyone, The organization I work for is beginning a redesign of our website and we're migrating from .Net 1.1 to 2.0. We currently use Visual Source Safe 6.0 for our source control and we barely use any of the functionality outside of checking files in and out (though I'm pushing to change that hopefully). So I've been researching other source control systems and, of course, ran across Team Foundation Server. I've spent most of the day researching the different "role" version of VS 2005 and found that our small development team wouldn't really need that (we have 3, sometimes 4 developers who write the code and then 2 or 3 people who do the HTML mark-up. Using something from the Team Suite might just be overkill). So my q ...Show All

• Visual Studio 2008 (Pre-release) Disable page input during asynchronous process

  This is the scenario: user clicks on a button; the button handler starts an asynchronous process and changes the page cursor to an hourglass; after the async process finishes, a callback function changes the cursor back to default. The problem I see is that changing the page cursor does not propagate to some controls which are still displaying the default cursor. Also, I don't know how to stop user's input while my async process is still running (short of disabling all the controls). The only solution I can think of is to show a modal dialog with a progress bar, but that's not what I want. So, these are my questions: 1. How can I change the cursor on the page and all the controls contained in it 2. How can I disable user's input o ...Show All

• Smart Device Development Communication between Windows mobile and a server system with WiFi/GPRS

  Hi I'm investigating the different opportunities for communication between Windows mobile and a server system with WiFi/GPRS. The solution that I try to find is the one that is most suitable for communication over network where the connectivity is very poor, like GPRS communication. My system must be able to "puch" information from a server out to registered mobile devices... Do anyone know if Microsoft already have application/systems that handle the communication part (like ActiveSync, ISA-server) so I can concentrate on my own business functions Right now I'm investigate MSMQ, Sockets or WebServices. What is the best solution for mobile system that need to handle real "push" over wireless communication ...Show All

• Software Development for Windows Vista Inconsistent File System Enumeration with FindFirstFile / FineNextFile

  I'm working to get a commercial application to run on Vista. Among the many broken things, the first one I encounter is a crash due to a stack overflow due to a recursive function that goes bad. The app enumerates files in various places using FindFirstFile | FineNextFile in a recursive function (C++). I'm using retail Vista Ultimate with VS 2005 sp1 plus the VS Vista update beta. What I see in the debugger is that when I start out enumerating drive "c:", I come to the "Documents and Settings" folder and recurse into it. When I get to "c:\Documents and Settings\All Users\Application Data", FindNextFile then returns "Application Data" over and over again and I recurse into "Application Data&qu ...Show All
