Data Types of Function calls
Since the USBDII was developed in the C++ language, some data types used may not be present
in the programming language you want to use. Please find the following data type conversion
table for your convenience:
HANDLE
An opaque 32-bit integer
BYTE
A 8-bit unsigned integer
BOOL
A 32-bit integer, either 0 (FALSE) or 1 (TRUE)
DWORD
A 32-bit unsigned integer
HWND
A 32-bit integer representing a valid handle to a Window
LPTSTR
A 32-bit flat pointer to a zero terminated string
LPBOOL
A 32-bit flat pointer to a variable of type BOOL
LPBYTE
A 32-bit flat pointer to a variable of type BYTE
LPDWORD
A 32-bit flat pointer to a variable of type DWORD
Also note that the DLL employs the Standard Call (Pascal) calling mechanism, which is used for
all system. USBDII as well and is compatible with VB, VC, Delphi, .NET, and notice the variable
with same type name may have different define in different program language. For example, in
Visual Basic 6, the width of Integer is 16 bits and the width of Long is 32 bits, but in Visual Basic.
Net, the width of Integer becomes 32 bits and the width of Long becomes 64 bits. If you declare
variable with different width from our define, it may cause some run-time error.
