• Visual FoxPro _screen.ContinuousScroll problem

  I noticed this problem just this morning after spending many hundred hours debugging my app for the past few months when everything worked just fine. This is the setup which is hardly unusual.

• Visual Studio 2008 (Pre-release) Positioning elements generated by a data template on a Grid or Canvas

  I'm trying to use an XML data source and a data template to generate some TextBlock elements from this data and present them using an ItemsControl. The TextBlocks are generated correctly, but I can't figure out how to position them on a Grid or Canvas panel. It seems the attached properties (Grid.Column, Grid.Row, Canvas.Left, etc) that I define on the TextBlocks are somehow ignored. This is the XAML code I'm using: <StackPanel xmlns="http ...Show All

• Visual Basic skins

  Do you guys know some sites where I can get custom skins for vb.net and how to use them Do you mean skins for VB itself, or for your apps Either way, I don't think they exist.

• Visual Studio 2008 (Pre-release) Expression Trees

  When creating an expression tree, the current Linq release requires me to explicitly state what the type of the expression is: Expression<Func<int,int,int>> expr = (x,y) => x + y; I cant even seem to be able to use type inference here: void GetExpression<T>(Expression<T> expr) { Console.WriteLine(typeof(T)); } GetExpression((x,y) => x+y); // error Do we think that the type inference is going to get better i ...Show All
