C语言SDK隐藏桌面

#include<windows.h>
#include<stdio.h>
int main()
{
 HWND hWnd;
 /*
 if(((hWnd = FindWindowEx(NULL, NULL, "Progman", NULL)) == NULL) ||((hWnd = FindWindowEx(hWnd, NULL, "SHELLDLL_DefView", NULL)) == NULL) ||((hWnd = FindWindowEx(hWnd, NULL, "SysListView32", NULL)) == NULL))
 {
  printf("获取桌面窗口失败！\n");
 }
 */
 while(1)
 {
    hWnd = FindWindowEx(NULL, NULL, "Progman", NULL);
 if(hWnd == NULL)
 {
  printf("未找到Progman!\n");
  system("pause");
 }
 hWnd = FindWindowEx(hWnd, NULL, "SHELLDLL_DefView", NULL);
 if(hWnd == NULL)
 {
      printf("未找到SHELLDLL_DefView!\n");
       
 }
 hWnd = FindWindowEx(hWnd, NULL, "SysListView32", NULL);
 if(hWnd == NULL)
 {
   printf("未找到SysListView32!\n");
 }
 else
    ShowWindow(hWnd,SW_HIDE);
 Sleep(1000);
 }
 return 0;
}

使用后，桌面会隐藏，任务栏不会隐藏，解决方法：

ShowWindow(hWnd,SW_SHOWNORMAL);

C-Free 5.0 windows XP下测试通过。
