VC如何实现电脑任意一个托盘图标的隐藏与再现？求解！！
RT，隐藏与再现电脑右下角托盘图标，并能处理隐藏后的空白区域。

我不管了，被人怀疑马甲刷分，没劲~

发TB_HIDEBUTTON消息隐藏后是会留下一块空白
用Shell_NotifyIcon吧
我修改了下，完美实现了：

C/C++ code


#define _WIN32_IE 0x0500

#include <windows.h>
#include <CommCtrl.h>

struct TRAYDATA
{
  HWND hwnd;                
  UINT uID;                
  UINT uCallbackMessage;    
  DWORD Reserved[2];        
  HICON hIcon;                
};

void ShowTrayIcon(LPCWSTR lpwszIcon, BOOL bShow)
{
  HWND hWnd,hWndPaper;
  DWORD dwProcessId;
  DWORD dwButtonCount;
  HANDLE hProcess;
  LPVOID lpAddress;
  TBBUTTON tb;
  
  hWnd = FindWindow(TEXT("Shell_TrayWnd"), NULL);
  hWnd = FindWindowEx(hWnd, 0, TEXT("TrayNotifyWnd"), NULL);
  hWndPaper = FindWindowEx(hWnd, 0, TEXT("SysPager"), NULL);
  if(!hWndPaper)
    hWnd = FindWindowEx(hWnd, 0, TEXT("ToolbarWindow32"), NULL);
  else
    hWnd = FindWindowEx(hWndPaper, 0, TEXT("ToolbarWindow32"), NULL);

  GetWindowThreadProcessId(hWnd, &dwProcessId);
  hProcess = OpenProcess(PROCESS_ALL_ACCESS
    |PROCESS_VM_OPERATION
    |PROCESS_VM_READ
    |PROCESS_VM_WRITE,
    0,
    dwProcessId);
  lpAddress = VirtualAllocEx(hProcess,0, 0x4096, MEM_COMMIT, PAGE_READWRITE);
  dwButtonCount = SendMessage(hWnd, TB_BUTTONCOUNT, 0, 0);
  
  for(UINT i = 0 ; i < dwButtonCount - 1; i++)
  {
    SendMessage(hWnd, TB_GETBUTTON, i, (LPARAM)lpAddress);
    ReadProcessMemory(hProcess, lpAddress, &tb, sizeof(TBBUTTON), 0);

    if(tb.iString != -1)
    {
      TRAYDATA trayData;
      WCHAR wszBuff[MAX_PATH] = {0};
      WCHAR *pwsz = NULL;
      ReadProcessMemory(hProcess, (LPVOID)tb.iString, wszBuff, MAX_PATH, 0);
      ReadProcessMemory(hProcess, (LPVOID)tb.dwData, &trayData, sizeof(TRAYDATA), 0);
      pwsz = wcsstr(wszBuff, lpwszIcon);
      if (pwsz)
      {
        NOTIFYICONDATA nid;
        nid.cbSize = sizeof(NOTIFYICONDATA);
        nid.hWnd = trayData.hwnd;
        nid.uID = trayData.uID;
        nid.uFlags = NIF_STATE;
        nid.dwState = bShow?NIS_SHAREDICON:NIS_HIDDEN;
        nid.dwStateMask = NIS_HIDDEN;
        Shell_NotifyIcon(NIM_MODIFY, &nid);
      }
    }
  }
  VirtualFreeEx( hProcess, lpAddress, 0x4096, MEM_RELEASE);
  CloseHandle(hProcess);
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
  ShowTrayIcon(L"音量", FALSE);  //隐藏音量图标
  //ShowTrayIcon(L"音量", TRUE);  //显示音量图标
  return 0;
}

------解决方案--------------------

探讨
冒昧再问一个问题：代码中 nid.uFlags 的值只给了三个提示：NIF_ICON， NIF_MESSAGE，NIF_TIP，也就是MSDN中的前三个属性值，代码中设置的NIF_STATE值被提示未定义，愚昧未能想到是什么原因。不知道能否请你帮忙解决一下。
