FIX: The VarUI4FromI4 function returns an incorrect value if a negative value is passed to the "lIn" parameter of the function in Windows Embedded CE 6.0 R3

Symptoms

Consider the following scenario:
  • You run an application on a Windows Embedded CE 6.0 R3-based device.
  • The application calls the VarUI4FromI4 function to convert variant data types from the LONG data type to the unsigned long (ULONG) data type.
  • The application passes a negative value to the lIn parameter of the function.
In this scenario, the VarUI4FromI4 function returns the S_OK code instead of the DISP_E_OVERFLOW code.

Cause

This issue occurs because the implementation of the VarUI4FromI4 function does not check the input parameter for negative values.
