Virtual PC - Copying image that was connected to a domain
There are a few issues that you need to deal with if the VM is joined to the domain. You will need to copy the relevant .vhd (disk image) and .vmc (config) files from the source, and then either:

1. Run sysprep on your copy (may break some software installs)
2. Or, manually change machine name
   • remove your copy from the domain (must be while disconnected from the network)
   • run newsid on the vm (available from sysinternals)
   • rename the vm
   • rejoin the vm to the domain

alterschema NewSchemaHere transfer ExistingSchemaHere.ObjectNameHere

Example: alter schema dbo transfer jpesch.tbl_SomeTable

This would transfer the table (tbl_SomeTable) from jpesch to dbo

c# Date validator function with Leap Year handling

public bool isDate(string strDate)
{
string strRegex = @"((^(10|12|0?[13578])([/])(3[01]|[12][0-9]|0?[1-9])([/])((1[8-9]\d{2})|([2-9]\d{3}))$)|(^(11|0?[469])([/])(30|[12][0-9]|0?[1-9])([/])((1[8-9]\d{2})|([2-9]\d{3}))$)|(^(0?2)([/])(2[0-8]|1[0-9]|0?[1- 9])([/])((1[8-9]\d{2})|([2-9]\d{3}))$)|(^(0?2)([/])(29)([/])([2468][048]00)$)|(^(0?2)([/])(29)([/])([3579][26]00)$)|(^(0?2)([/])(29)([/])([1][89][0][48])$)|(^(0?2)([/])(29)([/])([2-9][0-9][0][48])$)|(^(0?2)([/])(29)([/])([1][89][2468][048])$)|(^(0?2)([/])(29)([/])([2-9][0-9][2468][048])$)|(^(0?2)([/])(29)([/])([1][89][13579][26])$)|(^(0?2)([/])(29)([/])([2-9][0-9][13579][26])$))";

Regex re = new Regex(strRegex);
if (re.IsMatch(strDate))
return (true);
else
return (false);
}

This function will validate any date from 1800 -to 9999.
Also It will handle leap years.
Allowed formats are mm/dd/yyyy , m/dd/yyyy , mm/d/yyyy , m/d/yyyy.
