Add a Web Theme - November 2010
I have been using class module cTable a lot recently. It allows me to create various controls in an Asp:Table. I recently added theme selection options to the module. Theme support is provided in class module cTheme. This becomes the November 2010 tip-of-the-month. I wrote a VS/2008 Asp.Net, one page, web application project to demonstrate the features. Click here to run the demo. You may also want to review the January 2015 tip which shows how to create 'Fancy 3d Boxes'. Click here to view that tip.
2013/12/12 Added Gray and Green themes. 2015/01/15 Added a Purple theme and 3D effects.
The Demo Application
Run It - Click here to run the demo.
Select a color theme from the dropdown box.
Select 3D or not 3D samples.
This sample's color scheme changes after a theme is selected.
Here it was changed from Blue to Green and from 3D to not 3D.
The Blue Theme's 9 colors. The sorted order is used to set the cTable Color Properties.
This is a list of the cTable color properties.
This list changes when a theme is selected. The 'Blue' theme colors are displayed here.
Property gb3D determines whether 3D or non 3D table items are displayed.

This Enum defines 11 color themes. SetTheme(ByVal iTheme As eTheme, ByVal bSortEm As Boolean) This public subroutine sets up the theme colors. The colors are defined as hex constants. The colors are stored in a collection. iTheme The theme to be setup. bSortEm If True then sort the colors by weight. Black [#000000] being first and white [#FFFFFF] being last. Useful for displaying the colors from darkest to lightest. SetupThemeCTable(ByVal iTheme As eTheme) As cTable This public function defines a cTable. Appropriate theme colors are stored in the cTable's color properties. See above. Dim oT as cTable = SetupTheme(eTheme.e020Earth) iTheme The theme to be used.
