你知道怎么把变量变成字符串了吗?----关于wsprintf函数的用法
本帖最后由 BinGu 于 2012-1-12 22:58 编辑之前好多人问,怎么把变量变成字符串,这个问题确实难住了好多人!因为汇编语言里面没有wprintf这样的函数,确实让人头疼!但是汇编中有另外一个函数也能做到,相必不少人已经知道哪个函数了,不错,就是wsprintf函数!
wsprintf函数的用法:简单的说就是用wsprintf函数把变量格式化之后放入到缓冲区,然后就再冲缓冲区拿出来就是字符串了!明白了吗?嘿嘿~就是这么简单~~~

想~~大家应该都能看明白吧!
注意:看代码的时候,直接点击复制代码,然后粘帖到记事本中再看,那样格式就不乱了!
