How to get a random date in C#
I looked everywhere for a sample on generating random dates in C# but could find any so I wrote mine.
This function uses the DateTime utility class below which I found somewhere on the web.
///
private static DateTime getRandomDate(Random rand,
DateTime minDate, DateTime maxDate)
{
int totalDays = (int)DateTimeUtil.DateDiff(
DateInterval.Day , minDate, maxDate);
int randomDays = rand.Next(0,totalDays);
return minDate.AddDays(randomDays);
}
This function uses the DateTime utility class below which I found somewhere on the web.
public enum DateInterval
{
Day,
DayOfYear,
Hour,
Minute,
Month,
Quarter,
Second,
Weekday,
WeekOfYear,
Year
}
///
public sealed class DateTimeUtil
{
#region DateDiff Methods
public static long DateDiff(DateInterval interval,
DateTime dt1, DateTime dt2)
{
return DateDiff(interval, dt1, dt2, System.Globalization
.DateTimeFormatInfo.CurrentInfo.FirstDayOfWeek);
}
private static int GetQuarter(int nMonth)
{
if (nMonth <= 3)
return 1;
if (nMonth <= 6)
return 2;
if (nMonth <= 9)
return 3;
return 4;
}
public static long DateDiff(DateInterval interval,
DateTime dt1, DateTime dt2, DayOfWeek eFirstDayOfWeek)
{
if (interval == DateInterval.Year)
return dt2.Year - dt1.Year;
if (interval == DateInterval.Month)
return (dt2.Month - dt1.Month) +
(12 * (dt2.Year - dt1.Year));
TimeSpan ts = dt2 - dt1;
if (interval == DateInterval.Day ||
interval == DateInterval.DayOfYear)
return Round(ts.TotalDays);
if (interval == DateInterval.Hour)
return Round(ts.TotalHours);
if (interval == DateInterval.Minute)
return Round(ts.TotalMinutes);
if (interval == DateInterval.Second)
return Round(ts.TotalSeconds);
if (interval == DateInterval.Weekday)
{
return Round(ts.TotalDays / 7.0);
}
if (interval == DateInterval.WeekOfYear)
{
while (dt2.DayOfWeek != eFirstDayOfWeek)
dt2 = dt2.AddDays(-1);
while (dt1.DayOfWeek != eFirstDayOfWeek)
dt1 = dt1.AddDays(-1);
ts = dt2 - dt1;
return Round(ts.TotalDays / 7.0);
}
if (interval == DateInterval.Quarter)
{
double d1Quarter = GetQuarter(dt1.Month);
double d2Quarter = GetQuarter(dt2.Month);
double d1 = d2Quarter - d1Quarter;
double d2 = (4 * (dt2.Year - dt1.Year));
return Round(d1 + d2);
}
return 0;
}
private static long Round(double dVal)
{
if (dVal >= 0)
return (long)Math.Floor(dVal);
return (long)Math.Ceiling(dVal);

C# - How to check if a property type is an Enum
class EnumTests
{
public static void Run()
{
// convert a string into a color Enum
Colour c = (Colour)Enum.Parse(typeof(Colour), "Red", true);
Console.WriteLine("Colour Value: {0}", c.ToString());
// Picking an invalid colour throws an ArgumentException. To
// avoid this, call Enum.IsDefined() first, as follows:
string nonColour = "OrangeGreen";
if (Enum.IsDefined(typeof(Colour), nonColour))
c = (Colour)Enum.Parse(typeof(Colour), nonColour, true);
else
Console.WriteLine("'{0}' is an undefined Color", nonColour);
//Check if c is an Enum
Console.WriteLine("c is an Enum = {0} ", c.GetType().IsEnum);
}
}
#region Helper Classes
enum Colour
{
Red,
Green,

Apollo Extensions for Flexbuilder 2.0.1 won't Install/Run
After painstakingly downloading the new Apollo runtime and Apollo extensions for Flex Builder from Adobe Labs, I now have to deal with errors nobody at the Apollo forums seems to have any clue about. (Except another few 10s of developers who have the same problems).
I am running WinXP Pro SP2. During the Flex extensions install, I get to select the location of the Flex Builder folder and then I get an Eclipse Folder Error as shown below:
And I do not have Eclipse installed on this computer. I know Flex is built on Eclipse, but common, Adobe should be able to do better - I've been waiting for Apollo for too long.
The when I start Flex Builder, Apollo is present but still won't run.
I'm still watching the forums hoping somebody will answer this one.

Adobe.com is just Unacceptably TOO SLOW
As a matter of fact, this site doesn't even load.
Today I received an email from adobe to download the alpha release for the highly anticipated Apollo SDK for building desktop apps that will run on Windows & Mac. But unfortunaly for the last 10 minutes, the site still hasn't loaded.
Adobe.com is notoriously slow especially when compared to other tech company sites such as Yahoo.com and Microsoft.com.
Adobe, I have 2 questions.
1. Why should I even bother about your software when your site would load?
2. Is your site running on ColdFusion?
Bonus
3. Add I hear you want to put Photoshop on the web, good luck.

Yande's Home Coming
Yande and mother (Philo) finally came home on Thursday (3/15/2007). I will be putting up hist first home pictures later.
Apart from the Wheel Chair incident I still give Prince George's Hospital Center a solid A for their service. PG Hospital Center currently is run by Dimensions Healthcare System and I salute them for the excellent experience we had with their services. KUTGW.

Best Comparism: Ruby vs Java et al
This is probably the best analogy I've seen comparing dynamic languages (like Ruby & JavaScript) to static object oriented languages (like C# & Java) by Joel on Software.
