SortKeyEx

Sorts an array based on an array of keys. A subportion of the array can be sorted given a startindex and length. An optionally, supplied comparer object can be used to compare special elements, such as userdefined values.

 Public Sub SortKeyEx(
	  ByRef Keys As Variant,
	  ByRef Items As Variant,
	  ByVal Index As Long,
	  ByVal Length As Long,
	  Optional ByRef Comparer As Variant )

Parameters

Keys

[ByRef] Variant. An array the sorting is based on.

Items

[ByRef] Variant. An array that is sorted based on the sorting of keys.

Index

[ByVal] Long. The starting index in the array to start sorting.

Length

[ByVal] Long. The number of elements to be sorted.

Comparer

[ByRef] Optional. Variant. (Optional) An IComparer object or address of a comparer callback function.

Remarks

The Comparer parameter can be an IComparer interface or a callback address to a compare function using the AddressOf method. The callback method signature is defined as follows:

 Public Function SortCallback(ByRef x As <Type>, ByRef y As <Type>) As Long
     ' return less than zero if x is less than y.
     ' return greater than zero if x is greater than y.
     ' return zero if x equals y.
 End Function
