Creating a simple gradient using two colors is very simple:
Rectangle rect = new Rectangle(0, 0, 100, 100); LinearGradientBrush lgb = new LinearGradientBrush(rect, Color.White, Color.Blue, 90); e.Graphics.FillRectangle(lgb, rect); This code will generate a gradient in the given rectangle that goes from white to blue in a vertical way (see last parameter in constructor). In this case, e, is any class that encapsulates the System.Drawing.Graphics class. Once the gradient is ready, well, you have to actually draw it by calling the FillRectangle function.
Believe me, it is easy. As with any class, before we can use any of the Classes, Events and Objects available to us in the .Net Framework we need to import the Namespaces we need. For this we need 3 namespaces. VB.Net users only required 2 because VB.Net assumes the System Namespace, whereas C# isn’t so kind:
System System.Drawing System.Drawing.Printing These 3 Namespaces contain everything we need for this class, so you will need to add the following lines to the top of your class file:
There is a simple way to know this. The following code takes white (#ffffff) divided it by two as our reference color. If the comparing color is lower than the reference color, then the given color is dark, otherwise it’s light color.
function isLightOrDark($hexcolor) { return (hexdec($hexcolor) > 0xffffff/2) ? 'light color' : 'dark color'; }
You can assign a printer and other settings by using the basic PrintDocument and PrintDialog controls properties. Look at the next example:
if (printDialog.ShowDialog() == DialogResult.OK) { printDocument.PrinterSettings.PrinterName = printDialog.PrinterSettings.PrinterName; printDocument.PrinterSettings.Copies = printDialog.PrinterSettings.Copies; }

To update WordPress options with the new blog location, use the following SQL command:
UPDATE wp_options SET option_value = replace(option_value, 'http://www.old-domain.com', 'http://www.new-domain.com') WHERE option_name = 'home' OR option_name = 'siteurl'; After that you will need to fix URLs of the WordPress posts and pages, which translated from post slug, and stored in database wp_posts table as guid field.

If you are one of those who started surfing and creating the web in the 90’s, Reocities will take you back in time to the beginning of an era. Blue text on green or yellow wallpapers and animated gif’s overloaded the pages during the last decade of last century.
After Geocities closed in 2009, Reocities started saving a lot of websites stored on mentioned website trying to keep the history alive.
