ACC2000: How to Pass an Array as an Argument to a Procedure

• Microsoft Access 2000

SUMMARY

In order for a procedure to accept an array as an argument, the procedure must declare the array argument with opening and closing parentheses after the argument name. Additionally, when passing the array to the procedure, you must include parentheses after the array name, unless you are using Visual Basic. Otherwise, you may receive the error message "Parameter type mismatch" or "Duplicate definition."

MORE INFORMATION

The following example demonstrates the correct syntax for procedure declarations with an array:

Function YourFunctionName (InArray() As String) As Integer 

Sub YourSubName (InArray() As String) 

Result = YourFunctionName(YourArrayName()) 

YourSubName YourArrayName() 

Example

1. Create a module and type the following line in the Declarations section if it is not already there:




Option Explicit 

2. Type the following procedures:




'---------------------------------------------------------------
'The function LoadArray() loads an array called MyArray
'with string values. After loading the array, the function
'calls a procedure that outputs each array element
'to the Immediate window.
'---------------------------------------------------------------

Function LoadArray()
   Dim i as Integer
   ReDim MyArray(10) As String
   For i = 1 to 10
      MyArray(i) = "Test Value: " & i
   Next i
   DisplayArray MyArray()
End Function

'---------------------------------------------------------------
'LoadArray() Sub Procedure
'---------------------------------------------------------------

Sub DisplayArray (InArray() As String)
   Dim i as Integer
   For i = 1 to UBound(InArray)
      Debug.Print InArray(i)
   Next i
End Sub 

3. To test this function, type the following line in the Immediate window, and then press ENTER:

   
   ? LoadArray() 

   Note that the following list appears the Immediate window:




   Test Value: 1
   Test Value: 2
   Test Value: 3
   Test Value: 4
   Test Value: 5
   Test Value: 6
   Test Value: 7
   Test Value: 8
   Test Value: 9
   Test Value: 10
