Character Movement with packet

Hi I can send packet but cant figure out how to simulate character movement.I am trying these code but it has no effect. Can someone help me please ?

Code:

	        TPacketCGMove packet;
		packet.bHeader = 0x07;
		packet.bArg = 0x01;
		packet.bFunc = 0x00;
		packet.bRot = 0x30;
		packet.lX = 24234;
		packet.lY = 157208;
		packet.dwTime = GetServerTime();

		

		SendData(classPTR, 16, &packet);
		SendSequence(classPTR);
