• Visual Studio 2008 (Pre-release) Sorting a ListBox of strings

  Hey, This really should be incredibly easy to do but all I can find is huge explanations of how to use CollectionViews, Observable whatnots, SortDescriptions etc. In code, I want to be able to add ["Cat", "Dog", "Ant", "Bat"] to a ListBox, then be able to sort them... I've looked at SortDescriptions but have no idea what the first argument needs to be. Exceptions are thrown when i try things like "Content", "Name", "Text"... what properties to simple strings have I really do want to avoid XAML for this bit as it isn't ideal, code, a couple of lines... Thanks, Adam Miles Hi ,Try like this. void Click( object sende ...Show All

• Visual Studio Sandcastle November CTP - Issues with some xml tags.

• Visual Studio Express Editions error C2653: 'std' : is not a class or namespace name Resolved. needs to be more public

• Windows Forms FAQ for Winforms designer section

  shouldn't there be an FAQ for this section i have participated in this section when it was under windowsforms.net and i noticed that the same questions has been asked (like how to notify the designer host for a particular component property change, etc.) i know that online resources for designer related articles are scarce and it will really be helpful for starters to know where these links are. joeycalisay wrote: The usual sir, filtering out unwanted inherited properties for components using designers, change notification of properties at designtime, design-time integration basics, etc. maybe even post the useful articles online about designers...

• Visual Basic Login Class Problems!!!

  I decided to make a simple to use stand alone dll that would expose one function - AllowAccess(Title, NoAttemps, etc) as boolean. This would be called at the main programs Load event, if it returned False the program would close, if true it would keep going. Basically the dll has a class full of controls that i have yet to add, and a form class (frmLoginGUI). This is already dimentioned, but not initialised when the function is called. I want the function to run a form, allow the user to exit, or have a set number of goes at the password. i also want the form to be a dialog form! Basically, i can't show the form and ask for x dialog results as the result is repeated and it just closes, but i don't want to call the show dialog method ...Show All
