Keeping Query Params in a Hashtable

Demonstrates how to use a Chilkat Hashtable to hold query params and re-emit as a query param string.

Note: The ToQueryString method was added in Chilkat v9.5.0.92.

//  Output for the above loop:

//  color = blue
//  name = Jack Sparrow
//  fruits = apples&oranges
//  txt = this is a test
//  movie = Pirates of the Carribean

//  Get all name/value pairs as a query parm string with values URL encoded
cQp := oHt:ToQueryString()

//  Result:
//  color=blue&name=Jack%20Sparrow&fruits=apples%26oranges&txt=this%20is%20a%20test&movie=Pirates%20of%20the%20Carribean
