      • I¡¯d love to transfer over to using LINQ but I have not been able to figure out how to rewrite my security functionality in my current home-brew datalayer. I¡¯d also like to hear how other people implement user access security within their applications for ideas. My current application uses a data layer for SQL that I took from an open source library and modified heavily. One key feature I ad

      • I searched around and could not find an answer to my problem. I have a button that has a style with some triggers on the control template. When I run the application (sample code below) the IsMouseOver trigger works just fine. Then I click on the 'Disable' button that sets btn3's IsEnabled to false and this animation works fine as well. Then I click on 'Enable' and set btn3's IsEnabled to true and

Excel makes heavy use of reverse/inverse drawing: black is highlighted as white, white is highlighted as black, red is aqua, etc. This was done in WinForms using a VERY complicated method of drawing onto a bitmap, masking the bitmap and then combining the bitmap image with an invers

      • I am comparing the behaviour of the DOM AppendChild method with the Add method of XElement/XContainer.
