Keeping Query Params in a Hashtable

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

Dim success As Boolean
success = False

Dim ht As New Chilkat.Hashtable

// Add name/value pairs from an existing query param string where the values are already URL encoded.
Dim qp As String
qp = "txt=this%20is%20a%20test&color=blue&fruits=apples%26oranges"
success = ht.AddQueryParams(qp)

// Add some additional name/value pairs.
success = ht.AddStr("name","Jack Sparrow")
success = ht.AddStr("movie","Pirates of the Carribean")

// Iterate over the hash table to show what we have..

Dim keys As New Chilkat.StringTable
success = ht.GetKeys(keys)
Dim numKeys As Int32
numKeys = keys.Count
Dim key As String
Dim val As String
Dim i As Int32
i = 0
While i < numKeys
    key = keys.StringAt(i)
    val = ht.LookupStr(key)
    System.DebugLog(key + " = " + val)
    i = i + 1
Wend

// 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
qp = ht.ToQueryString()
System.DebugLog(qp)

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