• Visual Basic Help needed on defining Event Handlers via Function

  I am having problems associating event handling with Menu Item clicks. My application has many screens and I need to ensure the same "look & feel" for the Menus on each screen. I have created a function that can be called during a Form Load routine, that will add standard Menus & Menu options to any screen form. I need to be able to associate an appropriate Event Handling routine with, say, the Click Event for each Menu option but the Event Handler must be a different one for each Form so that it can deal specifically with the dataset displayed in that screen. I can't use WithEvents as the actual MenuItem objects are created via the public function and just added to the screen form menu I get the this exception from the ...Show All

• Visual Studio 2008 (Pre-release) Why BitmapEffects are Slow ?

  Hi! I want to make a photo gallery application that displays the groups of pictures like Phodeo. Each group is composed from a grid which contains a ScrollViewer and a TextBlock to show the name of the group. I want that around the grid a shadow to appear, so I use the ShadowBitmapEffect. What I found is that animations are very,very slow when I use the BitmapEffect Why Aren't the effects rendered in 3D And another question: which is the better way to modify, for example, the size of an object. It's better to set manually the properties (Width,Height), or to use a ScaleTransform Thank you! Well said, Jer! Ditto! I think folks easily forget some of the tricks (a.k.a., hacks) they've had to use to ...Show All

• Smart Device Development how can i convert my CF1.0 app to CF2.0

  Hi, I've created an app in VS2003. Now i want to upgrade to VS2005. I tried to do the same, but the upgradation wizard is converting the app to a version of CF1.0 app in 2005. This is not sufficient for me because i need to make use of the new features available in CF2.0 in my app. Is there any possibility to do this. If its not possible, then theres no point in converting the app to VS2005. Please suggest! - Hari Hi, To use the power of .NETCF 2.0; upgrade wizard is not a right solution. to do so follow the following steps 1. Create a new solution in .NETCF 2.0 2.

• .NET Development WPF Eng - Real New to Security

  Hey everyone, We are building a WPF app that will dynamically (reflection) load WPF user controls. AppDomains are out. For the sake of argument say I wanted to completely dissuade user controls from using any disk I/O at all. Could I require that the following attribute be used [assembly: FileIOPermission( SecurityAction.RequestRefuse, Unrestricted = true )] We don’t find the attribute, we don’t load the control. My tests show this works but security is too wide an issue for me to know for sure at this point. I’m not sure there isn’t a programmatic method around this. Obviously there are many permissions and we might have to require lots to really know the control won’t be mischievous. Thanks in Advance Ted ...Show All

• Visual Studio 2008 (Pre-release) Xml Data Binding Performance Issue (Re-post)

  I am running the .Net 3.0 RTM and have come across a performance problem with data binding. I am data binding XML which is updated once per second to a ListView/GridView . I have noticed that cpu utilization increases rapidly as the number of items in the ListView grows. For example, on my IBM Thinkpad 43p, if I have 3 items, cpu utilization is 8%. If I have 6 items cpu usage grows to 30%. At 12 items it is approaching 100%. As the number of lines of XML grows, the performance gets worse. In the code behind, I have a single XmlDocument that I set to the data context of the ListView: XmlDocument doc = new XmlDocument (); instrumentList.DataContext = doc; When new Xml is available, I do the following: doc.LoadXml(theX ...Show All
