Data Type Conversion Functions [Automation]

The files Oleaut32.dll (for 32-bit systems) and Ole2disp.dll (for 16-bit systems) provide the following low-level functions for converting variant data types. Higher-level variant manipulation functions (such as VariantChangeType) use these functions, but they can also be called directly.


If these functions are passed NULL pointers, there will be an access violation and the program will crash. It is your responsibility to protect these functions against NULL pointers.
