Handling Errors in the VBA Compiler

Runtime errors can occur when your compiled VBA code is executed. While standard VBA uses the On Error statement for error handling, the XLS Padlock VBA compiler uses a Try...Except block.

When an error occurs within the Try block (or any procedure it calls), the compiler will immediately jump to the Except block for handling.

Syntax #

Try
    ' ... Code to execute ...
Except
    ' ... Code to run if an exception occurs ...
End

Code Example #

NumberStr = ""
if InputQuery("Input", "Type an integer from 1 to 7", NumberStr) then
    try
        Number = StrToFloat(NumberStr)
    except
        raise("Not a valid number")
    end

    select case Number
        case 1
            ShowMessage("One")
        case 1 + 1
            ShowMessage("Two")
        case 4.5 / 1.5
            ShowMessage("Three")
        case 2 * 2
            ShowMessage("Four")
        case Length("xxxxx")
            ShowMessage("Five")
        case 3 + 3, 3 + 4
            ShowMessage("Six or Seven")
        case else
            ShowMessage("You did not type an integer from 1 to 7")
    end select
end if
