Parameter Passing

(OP)
guys, can you please tell me whats' the difference between the two.

old declaration:

VARIANT_BOOL GetAllUserInfo([in] LONG dwMachineNumber, [in] LONG *dwEnrollumber, [in] BSTR *Name, [in] BSTR *Password, [in] LONG *Privilege, [in] Variant_Bool *Enable)

new declaration:

VARIANT_BOOL GetAllUserInfo([out] LONG dwMachineNumber, [out] LONG *dwEnrollumber, [out] BSTR *Name, [out] BSTR *Password, [out] LONG *Privilege, [out] Variant_Bool *Enable)

may program posted a type mismatch, the ONLY DIFFERENCE that ive notice is the [in] and [out]. what's the meaning of IN, OUT? input output?

F1 guys!

RE: Parameter Passing

Yes, the [in] and [out] mark the parameters as input and out respectively.

Are you using C++/CLI?

Could you please post the code you are using this with so I can see what you are trying to pass to the method?
