我用的switch语句,不知为什么总报错，请看看，在先等待，马上给分

Question

CPoint pt;
  GetCursorPos(&pt);
  CMy750_clientApp* app = (CMy750_clientApp*)AfxGetApp();
  HMENU hmenu = LoadMenu(AfxGetApp()->m_hInstance,MAKEINTRESOURCE(IDR_MENU1));
  HMENU hpopup = GetSubMenu(hmenu, 0);
  switch(TrackPopupMenu(hpopup,TPM_RETURNCMD|TPM_RIGHTBUTTON,   
            pt.x,pt.y,0,m_hWnd,NULL))             
  {
case ID_Config1:  //配置中队
        
       m.Format(TEXT("%d"),(inifile.GetNumKeys()+1));
   ttt=m;
           //截取x=ip;y=netmask;z=gateway
   //   ".... .... ...."
   
   x = m_tree.GetItemText(m_tree.GetNextItem(TVI_ROOT,TVGN_CARET));
   temp=x.Mid(x.Find(" ")+1,x.GetLength());   
   z=temp.Mid(temp.Find(" ")+1,temp.GetLength());  
   x=x.Left(x.Find(" "));
   y=temp.Left(temp.Find(" "));
           
           //
           inifile.SetPath("test.ini");
           inifile.ReadFile();
   //根据中队名Name查找IP地址
           for(h=1;h<=(inifile.GetNumKeys());h++)
   {
             s.Format(TEXT("%d"),h); 
             if((inifile.GetValue(s,"Name"))==m_tree.GetItemText(m_tree.GetNextItem(TVI_ROOT,TVGN_CARET)))
 {
   x=inifile.GetValue(s,"Ip");
   y=inifile.GetValue(s,"NetMask");
   z=inifile.GetValue(s,"GateWay");
   ttt = s;
 }
   }
   ICspAdmin::CAMCFG *pCam = (ICspAdmin::CAMCFG *)m_tree.GetItemData(m_tree.GetNextItem(TVI_ROOT,TVGN_CARET));
   zzz dlg(pCam,ttt,m_tree.GetItemText(m_tree.GetNextItem(TVI_ROOT,TVGN_CARET)),x,y,z);
   dlg.DoModal(); 
   
   
   break;
case ID_Config3:
CSname dlg(NULL);
dlg.DoModal();
break;
这是我做的右健弹出式菜单的选择的语句，不过总报错，帮我看看，不胜感谢

Answer 1

要在case里面定义变量，需要用{}
比如
switch(a)
{
case 1:
   {
       int b=0;
   }
   break;
...

Answer 2

你的dlg不能在CASE里为变量,应放在SWITCH之前,这样就不会错了

Answer 3

case ID_Config3:
CSname dlg(NULL);
dlg.DoModal();
break;改为
case ID_Config3:
{
CSname dlg(NULL);
dlg.DoModal();
}
break;

Answer 4

给case里面加上
{
}

Answer 5

dlg放在switch前那还怎么选择呢，我就是要用switch选者打开哪个对话框
请详细说一下好吗

Answer 7

请参见MSDN的错误说明C2360,给出的例子和你的错误一样.

Answer 8

switch(TrackPopupMenu(hpopup,TPM_RETURNCMD|TPM_RIGHTBUTTON,   
            pt.x,pt.y,0,m_hWnd,NULL))             没有结束语句.

Answer 9

case ....
{        CSname dlg(NULL);
        dlg.DoModal();
        break;
}
