汗。。。csdn把tab键给遗漏掉了，重发
#include <windows.h>
#include <stdio.h>
#include <string.h>
int main(int argc,char *argv[])
{
printf( "Hello World! ");
{char arg[255] = {0};
arg[0] = '\ " ';
for(int i=0;i <strlen(argv[0]);i++)
arg[i+1] = argv[0][i];
arg[++i] = '\ " ';
arg[++i] = '\0 ';

HWND hWnd;
hWnd = FindWindow(0,arg);
if(!hWnd)
MessageBox(NULL, "aa ", "aa ",MB_OK);
ShowWindow(hWnd,SW_HIDE);
}
return 0;
}
