Interesting site for developing online without the use of Visual Studio or Zend Studio.

Not sure how useful it would be but it’s promising.

Adding indentation and headings to .NET DropDownList

Posted in C# Programming, VB .Net Programming on April 21st, 2010 by phoenixdigital

I have been able to add indentation to dropdown boxes to allow for easier user viewing in many languages… until I met .NET. For some reason when adding spaces to the text in a ListItem the spaces are magically removed.

I was wanting to acheive a DropDownList like below.

Also at the end of this post is a way to achieve the unselectable headings in the example above.

Number formatting in c#

Posted in C# Programming on April 13th, 2010 by phoenixdigital

A quick simple note on how to add prepending zeros to a number

int nMaxNumber = 3;
string strValue = string.Format("{0:0000}", nMaxNumber);

strValue will contain 0003

I will add more examples as I need them

C# Date formatting and Parsing

Posted in C# Programming on March 29th, 2010 by phoenixdigital

Here is a post so I can easily find the correct format for dates

// create date time 2008-03-09 16:05:07.123
DateTime dt = new DateTime(2008, 3, 9, 16, 5, 7, 123);

String.Format("{0:y yy yyy yyyy}", dt);  // "8 08 008 2008"   year
String.Format("{0:M MM MMM MMMM}", dt);  // "3 03 Mar March"  month
String.Format("{0:d dd ddd dddd}", dt);  // "9 09 Sun Sunday" day
String.Format("{0:h hh H HH}",     dt);  // "4 04 16 16"      hour 12/24
String.Format("{0:m mm}",          dt);  // "5 05"            minute
String.Format("{0:s ss}",          dt);  // "7 07"            second
String.Format("{0:f ff fff ffff}", dt);  // "1 12 123 1230"   sec.fraction
String.Format("{0:F FF FFF FFFF}", dt);  // "1 12 123 123"    without zeroes
String.Format("{0:t tt}",          dt);  // "P PM"            A.M. or P.M.
String.Format("{0:z zz zzz}",      dt);  // "-6 -06 -06:00"   time zone

as well as the way to call TryParseExact

DateTime completedDateEnd;
if (DateTime.TryParseExact(Request["completedDateEnd"], "yyyy-MM-dd", CultureInfo.InvariantCulture, DateTimeStyles.AssumeLocal, out completedDateEnd)
  // do stuff


also remember to add this to the using statements at the top of the page
using System.Globalization;

Sometimes you may be required to send some data to a remote site from the code behind via HTTP. Generally this can easily be perfomed if the site allows for GET submissions. However sometimes the site will only accept POST submissions.
