Demonstrate Binary Data Encoding Methods

Demonstrates binary data encoding methods.

Note: This example requires Chilkat v9.5.0.64 or later.

Dim binData As New Chilkat.BinData

// Append 10 bytes: 00, 01, 02, 03, 04, 05, 06, 07, 08, 09
Dim success As Boolean
success = binData.AppendEncoded("00010203040506070809","hex")

// Show that binData contains 10 bytes.
System.DebugLog("num bytes = " + Str(binData.NumBytes))

// Get as base64
System.DebugLog("base64: " + binData.GetEncoded("base64"))

// Get a chunk of the binary data.
// The 1st byte is at index 0.
// The output should be "02030405"
Dim offset As Int32
offset = 2
Dim numBytes As Int32
numBytes = 4
System.DebugLog("chunk: " + binData.GetEncodedChunk(offset,numBytes,"hex"))

// Copy the bytes to a StringBuilder using the base64url encoding
Dim sb As New Chilkat.StringBuilder
success = binData.GetEncodedSb("base64url",sb)
System.DebugLog("base64url: " + sb.GetAsString())

// Remove a chunk from the binary data
offset = 2
numBytes = 4
success = binData.RemoveChunk(offset,numBytes)
// The bytes remaining are 00,01,06,07,08,and 09
System.DebugLog("after removing chunk: " + binData.GetEncoded("hex"))
