VBA - call function without return variable

问题

i have function:

Function importCSV(fileName As Variant) As Boolean

' some code
' no importCSV = TRUE

end Function

i call this function

importCSV (fileName As Variant)

every do OK, bud when a modific function.

Function importCSV(fileName As Variant, linkToHeader As Boolean) As Boolean
    ' some code
    ' no importCSV = TRUE

end Function

i cant call function like this

importCSV (fileName As Variant, TRUE)

VBA detect syntax error and a must call

a = importCSV(fileName As Variant, TRUE)

Why?

回答1:

To avoid assigning the return value to any variable you can use call keyword

call importCSV(fileName As Variant, TRUE)

Additionally you can call the function this way:

importCSV fileName:="File name", linkToHeader:=TRUE
