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

Useful lookup of variable types available in c#

    public new TList<T> FindAll(Predicate<T> match) 
    {
      if (match == null)
        {
          throw new ArgumentNullException("match");
        }

      TList<T> result = new TList<T>();
      foreach (T item in this.Items)
      {
        if (match(item))
        {
          result.Add(item);
        }
      }
      return result;
    }

list.FindAll(delegate(TempAddItem t) { return t.ShortCode.Trim() == 'Test'; });

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.

Heading 1  This item  That itemHeading 2  This item  The other oneHeading 3  The item here    The item indented another level The item at the end

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

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
Ref: http://blog.stevex.net/string-formatting-in-csharp/

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;

Handy little program to test on the various versions of IE

IE Tester

Sure to cause no end of frustration getting layouts to look the same in all versions.

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.
