The VBA ISMISSING function is listed under the information category of VBA functions. When you use it in a VBA code, it evaluates if an optional argument is missing from the procedure and returns TRUE if it is else FALSE.

Syntax

IsMissing(ArgName)

Arguments

  • ArgName: The name of the argument (Optional) that you want to test if it’s supplied or not.

Example

To practically understand how to use the VBA ISMISSING function, you need to go through the below example where we have written a vba code by using it:

example-vba-ismissing-function
Sub example_ISMISSING(Optional myArg As Variant)
Range("A1").Value = IsMissing(myArg)
End Sub

In the above code, we have used ISMISSING to check the argument myArg is missing or not, and as we don’t specify anything for it, the function returns TRUE in the result.
