WinApi学习笔记简单的数据类型

#include <windows.h>
#include <stdio.h>

int WinMain(HINSTANCE hInstance,
			HINSTANCE hPrevInstance,
			LPSTR lpCmdLine,
			int nShowCmd)
{
	LPSTR szString = "Windows data type string";
	CHAR lpString[120];
	DWORD dwMax = 0xFFFFFFFF;
	DWORD dwOne = 0x1;
	INT iMax = 0xFFFFFFFF;
	INT iOne = 0x1;
	MessageBox(NULL,szString,"LPSTR",MB_OK);

	CopyMemory(lpString,szString,lstrlen(szString)+1);
	MessageBox(NULL,lpString,"CHAR[]",MB_OK);

	if(dwMax>dwOne)
	{
		MessageBox(NULL,"DWORD数据类型0xFFFFFFFF大于0x1","DWORD",MB_OK);
	}

	if(iMax<iOne)
	{
		MessageBox(NULL,"INT数据类型0xFFFFFFFF小于0x1","INT",MB_OK);
	}
}

DWORD是32位无符号整形数据
LPSTR是ANSI字符串变量
HANDLE 对象句柄
HINSTANCE程序实例句柄
HWND窗口句柄
HMODULE模块句柄
HKEY注册表句柄
INT_PTR指向INT型的指针
LPARAM消息的L参数
WPARAM消息的W参数
LPDWORD指向DWORD类型的指针
SIZE_T表示内存大小以字节为单位
