# Passing D3 Visual Basic objects

The following D3 Visual Basic object handles (using the
brHandle method available to each D3 Visual Basic object) can be passed
to a FlashBASIC subroutine:

| D3 Object | FlashBASIC Argument | Notes |
| --- | --- | --- |
| Dynamic Array | String | Only ANSI string can be passed. |
| File | File variable | The file must be opened in Visual Basic. The FlashBASIC subroutine can read and write the file, but must not close the file. File variables are not modified on return. In other words, it is not possible to pass an empty file object and have a FlashBASIC module open a file. Note: The module can open/close files within the module. However, the Visual Basic application will not have access to those files unless it also opens the file. |
| Select List | String | The Flash subroutine should not modify the input string. |
| All Others | Generate a Run Time Exception. | |
