Excel for mac vba to call a subroutine code#
The code below declares a function with an array as the return type: 'call the function with a two dimensional array as intputĭeclaring Functions With an Array as the Return Type: The code below uses a 2 dimensional array therefor an expetion will not be thrown and the result will be:ĭim arrInteger(1 To 4, 1 To 3) As Integer Since the previous code uses a 1 dimensional array, the exception will be thrown, therefore the message box below will be shown:

The error handler will catch the array and display a message box stating that the array was 1 dimensional. If the array is 1 dimensional then an exception will be thrown. After passing it to the Sub Example3, the Sub tries to get the upper bound of the second dimension. MsgBox ("The Input Array is 1 dimensionsal")ĪrrInteger1D is a 1 dimensional array. MsgBox ("The Input Array is 2 dimensional") Sub Example3(ByRef arrIntegers() As Integer) In order to get the dimensions of an array you would need to use an error handler. Getting the dimension of the array is not as straight forward. I have explained how you can get the size of the array in the article VBA, Working With Array. Therefor the size and dimensions of the array can only be obtained at runtime. Getting the Dimension of the Input Array to a Function or Sub:Īs mentioned in the previous sections when declaring a sub or functions with input parameters of type array you can’t define its size or dimensions. As you can see below the changes made to the copy had no effect on the original array: Sub Example2 takes a copy of arrIntegers as the input paramter and modifies the copy. 'modifies the copy of the input parameter Sub Example2( ByVal arrIntegers As Variant) 'call the function example 1 with arrIntegers being ByVal

In order to pass an array as an input parameter to a Sub or Function, ByVal you would need to use the Variant data type: Sub Example1(ByVal arrIntegers() As integer) The following declaration would generate a syntax error: Unlike other data types passing arrays ByVal is not as straight forward. Passing Arrays as Input Parameters to Functions and Subs ByVal: Note: The syntax for declaring a Function with an input parameter of the array data type is the same as that of a Sub. Note: You cannot set the size of the array input array in the declaration of the Sub or Function. Sub Example1(ByRef arrIntegers() As Integer)įor i = LBound(arrIntegers) To UBound(arrIntegers) 'prints the values in arrIntegers to column A 'call the function example 1 with arrIntegers as an input parameter 'populates the array with the values 1 to 10 Sub Example1 prints the array values to column A: Populates the array with the values 1, 2, 3, …, 10. The code below creates the array arrInputIntegers.
