vc使用技巧汇集

在vc中如何在点击对话框最小话按纽后，对话框加如系统右下角的任务栏中。就好比点中qq的最小化窗口所实现的功能一样，在vc中有没有这样的函数或其他类似的工具！谢谢~~~~~~~~

1。首先你需要在WM_SYSCOMMAND消息中截获SC_MINIMIZE标记  
 
void  CMainFrame::OnSysCommand(UINT  nID,  LPARAM  lParam)  
{  
               if  ((nID  &  0xfff0)  ==  SC_MINIMIZE)  
               {  
                 触发你的Shell程序  
                 }      
                 CFrameWnd::OnSysCommand(nID,lParam);  
}  

实现托盘图标的代码：  
 
///===================托盘图标======================================  
#define    WM_TRAY  WM_USER+100    自定义信息，所以还要定义函数  
 
LRESULT  CFDlg::WindowProc(UINT  message,  WPARAM  wParam,  LPARAM  lParam)    
{  
           //  TODO:  Add  your  specialized  code  here  and/or  call  the  base  class  
           if(message==WM_TRAY)  
                       return  OnTray(wParam,lParam);                          
           return  CTabDialog::WindowProc(message,  wParam,  lParam);  
}  

LRESULT  CFDlg::OnTray(WPARAM  wParam,LPARAM  lParam)  
{  
           if(wParam!=IDR_MAINFRAME)  
                       return  0L;  
           CMenu  menu,*pSubMenu;  
           CWnd  *pTarget=AfxGetMainWnd();  
           if(LOWORD(lParam)==WM_RBUTTONUP)  
           {  
           if(!menu.LoadMenu(IDR_SYSTEMMENU))    return  0;  
           if(!(pSubMenu=menu.GetSubMenu(0)))  return  0;  
           ::SetMenuDefaultItem(pSubMenu->m_hMenu,IDR_SYSTEMMENU,0);  
           CPoint  pos;  
           GetCursorPos(&pos);  
           ::TrackPopupMenu(pSubMenu->m_hMenu,0,pos.x,pos.y,0,pTarget->GetSafeHwnd(),NULL);  
           pTarget->PostMessage(WM_NULL,0,0);  
           menu.DestroyMenu();  
           }else  if(LOWORD(lParam)==WM_LBUTTONDBLCLK)  
                                     this->ShowWindow(SW_SHOW);  
return  0;  
}  
 
//----------------隐藏图标-----------------------  
 
void  CFDlg::OnHide()                    
{  
           NOTIFYICONDATA  tnd;  
           tnd.cbSize=sizeof(NOTIFYICONDATA);  
           tnd.hWnd=this->m_hWnd;  
           tnd.uID=IDR_MAINFRAME;  
           tnd.uFlags=NIF_MESSAGE  |NIF_ICON  |NIF_TIP;  
           tnd.uCallbackMessage=WM_TRAY;  
           tnd.hIcon=LoadIcon(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDR_MAINFRAME));  
           strcpy(tnd.szTip,"你的标题");  
           ::Shell_NotifyIcon(NIM_ADD,&tnd);  
           this->ShowWindow(SW_HIDE);  
}  
 
//--------------------删除托盘图标---------------  
int  CFDlg::DeleteIcon()  
{  
           BOOL  res;  
           NOTIFYICONDATA  tnd;  
           tnd.cbSize=sizeof(NOTIFYICONDATA);  
           tnd.hWnd=this->m_hWnd;  
           tnd.uID=IDR_MAINFRAME;  
           res=Shell_NotifyIcon(NIM_DELETE,&tnd);  
           return  res;  
}
