Posted on

Hello all.

hope doing well …

here is another tip related to C# programming …. i found it useful so sharing with you people …   this is how you can format date in different format in asp.net / C#

the usage is as follows

<%= String.Format(“{specifier}”, DateTime.Now) %>

where the possible specifiers are given below.

D Long Date 15 June 2010
t Short Time 21:08
T Long Time 21:08:59
f Full date and time 15 June 2010 21:08
F Full date and time (long) 15 June 2010 21:08:59
g Default date and time 15/06/2010 21:08

C# Color Names And Codes

Posted on Updated on

Last night i was working on a project of C# and required some color schemes for row color of a grid, and first time i got familiarity with System.Drawing namespace.  Its simply amazing …. really solved my many problems in just playing mode. First i use its colors and thought should share with you people. Some others features will discuss some other time..

Hear are the color codes are taken from the HTML specifications, whose names correspond to the names given for the .KnownColor attributes. For example, to get one of these color schemes, you would write

Color c = Color.FromKnownColor(KnownColor.colorname)

where colorname is from the table below. The values are also supplied; so you could use the FromArgb method to create the color. The following two lines produce the same color:

Color c1 = Color.FromArgb(32,178,170);
Color c2 = Color.FromKnownColor(KnownColor.LightSeaGreen);

In the table, I have assigned the exact color values given. The rendering you actually see will depend upon whether or not your browser honors 24-bit color requests (some browsers will map colors to the “nearest Web palette color”), the adjustments to your monitor, and the corrections your video card applies.

MonoTouch: Building iPhone Apps Using C# and .NET

Posted on Updated on

Novell has released MonoTouch 1.0, what it claims is the industry’s first solution for developing applications for the iPhone and iPod Touch using the Microsoft .NET Framework, including C# and other .NET programming languages. Until now, developers primarily built iPhone

.netmlototouch

applications using C and Objective-C. With MonoTouch, the creativity of millions of .NET developers worldwide can be unleashed to build a vast array of iPhone applications.

Developed by the Mono Project, an open source initiative sponsored by Novell, MonoTouch simplifies iPhone development by letting developers utilize code and libraries written for the .NET development framework and programming languages such as C#.

MonoTouch is an SDK that contains a suite of compilers, libraries, and tools for integrating with Apple’s iPhone SDK. Microsoft .NET base class libraries are included, along with managed

libraries for taking advantage of native iPhone APIs. Also included is a cross-compiler that can be used for turning .NET executable files and libraries directly into native applications for distribution on the Apple Apps* Store or for deployment to enterprise iPhone users. In addition, Xcode integration enables application developers to test on the device or in Apple’s iPhone Simulator and ship applications to the Apple Apps Store for distribution.

“The vast majority of Windows-centric developers, ISVs and IT organizations have chosen the C# language and .NET for development,” said Miguel de Icaza, Mono project founder and Developer Platform vice president at Novell. “As such we have seen tremendous demand for tools to build .NET-based iPhone applications. We developed MonoTouch in response to this demand, giving both individual developers and businesses a solution that breaks down the barriers to iPhone application development.”

MonoTouch Personal and Enterprise Editions are available now through shop.novell.com. MonoTouch Enterprise Edition is available for $999 per developer for a one-year subscription, which includes maintenance and updates. A five-developer Enterprise license supports five concurrent developers and is available for US $3,999 per year. For individuals only building applications for the Apple Apps Store, MonoTouch Personal Edition is available for $399 per developer for a one-year subscription.
