.NET GENES

Hi, Lately, I was given a task from a client if I can update my VB.NET crawler scripts with a webbrowser control to show/render images of the crawled website to the control. Normally, I used the control just to obtain the web page source and then parse the necessary information. By default, the settings of the webbrowser control is IE7. After doing some reseach, I stumbled upon a solution by Noseratio on IE Feature Control Hacks . The documentation for browser emulation can be found on MSDN: MSDN Browser Emulation . I uploaded a sample VB.NET application here: WebBrowser Control Similar to IE Browser Sample Result: Cheers! :)

Here's a snippet on how to retrieve running process in your computer by array names using LINQ. C# Code 1 2 3 4 5 6 7 8 List<Process> procs = new List<Process>(); procs = new List< string >() { "firefox" , "iexplore" , "ssms" , "notepad++" , "chrome" } .SelectMany(o => Process.GetProcessesByName(o)).ToList(); foreach ( var item in procs) { Console.WriteLine(item.ProcessName); } VB.NET 1 2 3 4 5 6 Dim procs As IEnumerable( Of Process) = _ { "firefox" , "iexplore" , "ssms" , "notepad++" , "chrome" }.SelectMany(Function(proc) Process.GetProcessesByName(proc)) For Each p In procs Console.WriteLine(p.ProcessName) Next Console.ReadLine() Output

Below are extension methods in accessing WPF DataGrid Rows and Cells. These methods were based on existing C# methods and I converted them to VB.NET for VB programmers.

In programming, it's a common exercise to show triangle shapes using the asterisk character. Well, this can be achieved using TSQL as well. Script #1 DECLARE @Total1 INT DECLARE @ctrOuter1 INT DECLARE @ctrInner1 INT DECLARE @strPrint1 VARCHAR(100) SET @Total1 = 5 SET @ctrOuter1 = @Total1 SET @strPrint1 = '' WHILE @ctrOuter1 >= 1 --outer loop BEGIN SET @strPrint1 = '' SET @ctrInner1 = 0 WHILE @ctrInner1 <= (@Total1 - @ctrOuter1) BEGIN SET @strPrint1 = @strPrint1 + '*' SET @ctrInner1 = @ctrInner1 + 1 END PRINT @strPrint1 SET @strPrint1 = @strPrint1 + CHAR(13) SET @ctrOuter1 = @ctrOuter1 - 1 END Output: Script #2 DECLARE @Total INT DECLARE @ctrOuter INT ...
