structure typedefs error

[pobri19]

Hi, I'm trying to typedef a structure, and a pointer to a structure, but I'm getting compiler errors and I don't understand why. I'm using Visual C++ 6.0. Basically I want LPSTYLESTRUCT to be a pointer to STYLESTRUCT, here is my code:

typedef struct {
    DWORD styleOld;
    DWORD styleNew;
} STYLESTRUCT, * LPSTYLESTRUCT;

int main() {
	
	STYLESTRUCT styleStruct;
	LPSTYLESTRUCT lpStyleStruct;

	lpStyleStruct = &styleStruct;
}

And here are the errors:

error C2371: 'STYLESTRUCT' : redefinition; different basic types
        c:\program files\microsoft platform sdk\include\winuser.h(2773) : see declaration of 'STYLESTRUCT'

error C2371: 'LPSTYLESTRUCT' : redefinition; different basic types
        c:\program files\microsoft platform sdk\include\winuser.h(2773) : see declaration of 'LPSTYLESTRUCT'

Thanks.

This same struct with the same typedef's is already defined in "winuser.h". Why don't you just use that one?
