You can run this script with Windows Scripting Host by invoking
cscript.exe from the Windows command shell, or by using wscript.exe
from Windows Explorer.

var emailaddr = null;
var subject = null;
var objArgs = WScript.Arguments;
if(objArgs.length >= 1) {
    emailaddr = objArgs(0);
    if(emailaddr.substr(0, 7) == "mailto:")
        emailaddr = emailaddr.substr(7);
}

cscript.exe mailto:test@foobar.com causes emailaddr = test@foobar.com.

I would to modify the above to have cscript.exe malito:test@foobar.com?Subject=help to cause emailaddr = test@foobar.com and then subject=help

THANKS!

  var objArgs = WScript.Arguments;
  if(objArgs.length >= 1) {
    var strArr = objArgs[0].split('?');
    emailaddr = strArr[0];    
    if(emailaddr.substr(0, 7) == "mailto:")

how about,

var strArr = objArgs(0).split('?');

replacing [] with ()

Almost there!!

mailto: -=> works
mailto:test@foo.com -=> works
mailto:test@foo.com?subject=test -=> works
mailto:test@foo.com?abc=test -=> causes emailaddr = test@foo.com, subect = test, here the email is correct, there is no subject specified though....

opps ignore the first three lines. that should not be there, my bad.

var emailaddr = null;
  var subject = null;
  var objArgs = WScript.Arguments;
  if(objArgs.length >= 1) {
    var strArr = objArgs(0).split('?');
    emailaddr = strArr[0];    
    if(emailaddr.substr(0, 7) == "mailto:")
        emailaddr = emailaddr.substr(7);
    if(strArr.length >= 2){
      var subjectArr = strArr[1].split('=');
      if(subjectArr[0]=='subject'){
        subject = subjectArr[1];
      }
    }  
  }

mailto: -=> works
mailto:test@foo.com -=> works, but subject comes up as null, should be blank
mailto:test@foo.com?subject=test -=> works
mailto:test@foo.com?abc=test -=> causes emailaddr = test@foo.com, subect = null, should come up as blank
mailto:test@foo.com?Subject=test -=> subject is blank (should be case insensative on SubJect

so close... thanks!!!!

you can initialize it to ''

var emailaddr = '';
var subject = '';

for the case sensitivity issue, i provided the answer above.
