ListView_GetItemText 无法获取内容

是这样的吧，不能获取其它进程的填到自己进程的内存块里；可以通过 VirtualAllocEx() 在对方进程里分配块内存，用来存放获取的内容，然后 ReadProcessMemory() 再从那里复制到自己进程里来。
网上有很多示例的，如 http://bbs.csdn.net/topics/360118263

int iNumSt = 5;

还是木有办法读取这个是网上的,听说已经读取了,是不是和我的系统有关,WINDOWS7

非管理员级的不同用户间的进程，这个代码也是不行的，CreateProcess() 会被拒绝，因为没有 debug 权限；通常只有管理员的才可以获取其他用户的进程的内容。你 3# 的这个代码，xp 下是不行的吧，win7 应该可以的；因为默认地，vc 好像将 PROCESS_ALL_ACCESS 整成了 0x1FFFFF，但对 xp 来说，这个值得是 0x1F0FFF 。

                      if (strstr(szText,hint1) != NULL)
                      {
                         a+=1;
                      }
                  }
            CloseHandle(hProcess);
            }
为什么获取不到内容呢？

你这好像是想直接从其它进程的 LV控件里读取啊，当然不行了，上面已经解释过的。
可以参考上面也提及的下面的这个帖子里的具体的操作方法；网上搜索下也行，有不少这方面内容的。
