Hello,

I'm writting my first pluggin and I sort of have the idea, but for some reason when I call ?GetXSize@@YAKH@Z (this is what i preseume is Object Size X) it returns a different number to what Object Size X does when i call them.

for example

my C++ function is

+ Code Snippet

int MY_GET_OBJECT_SIZE_X( int oId )
{
	typedef int (*FPOINTER)(int);
	HMODULE hDBPCommands = LoadLibrary("DBProBasic3DDebug.dll");
	FPOINTER ObjectSizeX = (FPOINTER)GetProcAddress( hDBPCommands, "?GetXSize@@YAKH@Z" );
	FreeLibrary( hDBPCommands );
	return ObjectSizeX(oId);
}

and in dbpro i call

+ Code Snippet

	text 0, 0, Str$(MY GET OBJECT SIZE X( 1 ))
	text 0, 14, Str$(Object Size X(1))

but my command outputs some large number around the 10millions and the native command outputs 10 (well 9.99999999)

any ideas why?

Yours

You have got the correct name for the function, but you haven't got the right typedef:

typedef DWORD (__cdecl *FPOINTER)(int);

Also, I'd guess that your resource string is returning an 'int' too, when it should be returning a float - change the first character in your resource strings arg types from an L to an F.
