用invoke    GetWindowText,hWnd,addr @buf,sizeof @buf得到的buf


如何遍历@buf字符窜的每一个字母

szBuff db 100 dup (?)
szFmat db '%d',0

----------------------------
invoke lstrlen,addr @buf

mov ecx,eax
lea esi,@buf
NextWord:
invoke wsprintf,addr szBuff,addr szFmat,[esi]
invoke MessageBox,NULL,esi,esi,0
inc esi
loop NextWord



未测试~

呃，显示字符，应是要s 上面的改为%s

格式化字符%c
格式化字符串%s
整数%d

wsprintf不支持格式化浮点数

不行啊
invoke wsprintf,addr szBuff,addr szFmat,[esi]
这句报错,[esi]不能直接放在这里

.Data
szTxt        db    'abcdefghigklmnopqrst1234567890',0
szFmt        db    '%c',0
szCap        db    '单字符格式化',0
 
.Data?
szBuff    db 100 dup (?)
 
.Code
 
Start:
 
    lea    esi,szTxt
     
    .While BYTE ptr [esi]
         
        invoke    wsprintf,addr szBuff,addr szFmt,DWORD ptr [esi]
        invoke    MessageBox,NULL,addr szBuff,addr szCap,0
         
        inc esi
    .EndW
 
End Start

对的,但只能输出英文,如何输出中文

笨方法 转Unicode %C格式化

转Unicode?


如何转,我是新手
