Windows Forms	A method to move rows within a DataTable [Tip/Trick] 13 Jan 2012 Updated: 13 Jan 2012 Rating: 3.86/5 Votes: 6 Popularity: 3.00 Licence: CPOL Views: 16,720 Bookmarked: 2 Downloaded: 0 Please Sign up or sign in to vote. Nice solution agent154, I'd just suggest to implement it as extension methods for data row: (and I don't liked your "error reporting" with the '0' Value - because '0' could be a valid index). But I have to say, even if you don't have a database behind the datatable you can use sorting (LINQ,...

C#	Close Application at Press of Escape Button [Tip/Trick] 1 Jul 2011 Updated: 1 Jul 2011 Rating: 4.83/5 Votes: 4 Popularity: 2.91 Licence: CPOL Views: 10,623 Bookmarked: 1 Downloaded: 0 Please Sign up or sign in to vote. Your tip is useful for main forms with no close or cancel button. But most time you will want the "escape-close-form-behaviour" only with dialogs. This is the recommended way to do it: (Now i see Indivara already mentioned it in the comments)using System;using...
	Following object inheritance [Tip/Trick] 21 Jul 2010 Updated: 23 Jul 2010 Rating: 5.00/5 Votes: 1 Popularity: 0.00 Licence: CPOL Views: 4,080 Bookmarked: 1 Downloaded: 0 Please Sign up or sign in to vote. OriginalGriff has made a nice and small class. But I don't think I would use this code in an application. Most times when I want to know about the inheritance chain of an object is while I'm coding. So a quick and nice (commandline?) tool would be a better fit, I think. The problem with...
	Find a Parent Control Recursively [Tip/Trick] 24 Sep 2010 Updated: 24 Sep 2010 Rating: 4.67/5 Votes: 2 Popularity: 1.40 Licence: CPOL Views: 19,301 Bookmarked: 5 Downloaded: 0 Please Sign up or sign in to vote. Useful function, but I don't see any need for an recursion here. I'd solve it like this:private static Control FindControlParent(Control control, Type type) { Control ctrlParent = control; while((ctrlParent = ctrlParent.Parent) != null) { ...
	How to convert BMP to GIF in C# [Tip/Trick] 21 Dec 2010 Updated: 21 Dec 2010 Rating: 4.67/5 Votes: 3 Popularity: 2.23 Licence: CPOL Views: 11,331 Bookmarked: 1 Downloaded: 0 Please Sign up or sign in to vote. I think your solution is good if I have to control quality, compressionetc.For a fast conversion I do just this.Bitmap bmp = new Bitmap(@"C:\Example.bmp");bmp.Save(@"C:\Example.gif", ImageFormat.Gif);
	Is operator working simulation [Tip/Trick] 12 Jul 2011 Updated: 12 Jul 2011 Rating: 5.00/5 Votes: 2 Popularity: 1.51 Licence: CPOL Views: 6,161 Bookmarked: 0 Downloaded: 0 Please Sign up or sign in to vote. I think your function is no (theoretical) replacement for the is operator.The is operator takes an object (left) and a type (right) as arguments, not two objects.The is operator considers inheritance. Look at this (executable) example:using System;namespace IsOperatorCheck{ ...
	Convert Text to Image [Tip/Trick] 27 Nov 2011 Updated: 27 Nov 2011 Rating: 5.00/5 Votes: 2 Popularity: 1.51 Licence: CPOL Views: 9,310 Bookmarked: 3 Downloaded: 1 Please Sign up or sign in to vote. I'd like to offer a "funny" alternative by using a dummy TextBox. public static Bitmap GetPlainTextBitmap(string strText, Font font, Color colorBack, Color colorText, Size sizeTargetBitmap) { // Create a dummy TextBox TextBox txDummy = new TextBox(); ...
	C# equivalent of VB's With keyword [Tip/Trick] 15 Feb 2012 Updated: 15 Feb 2012 Rating: 4.00/5 Votes: 1 Popularity: 0.00 Licence: CPOL Views: 5,250 Bookmarked: 0 Downloaded: 0 Please Sign up or sign in to vote. It's not realy an alternate - but I think it should be mentioned. Most time you have this kind of code during initialization. So why not use this:StatusProgressBar spb = new StatusProgressBar() { IsIndeterminate = false, Visibility = Visibility.Visible, ...
C# 4.0	Attaching a Console to a WinForms application [Tip/Trick] 18 Jan 2012 Updated: 18 Jan 2012 Rating: 5.00/5 Votes: 3 Popularity: 2.39 Licence: CPOL Views: 14,900 Bookmarked: 2 Downloaded: 0 Please Sign up or sign in to vote. Very good tip. I just want to mention an alternative - you can just change your project output type to a console application. (You can undo it later if only needed for debugging). So if you started with a Windows Forms project in Visual Studio: Go to project properties/application/ and in the...
