1. 如何激活和关闭IE浏览器
//激活并打开IE
void lounchIE()
{
HWND h=FindWindowEx(NULL,NULL,NULL,
"Microsoft Internet Explorer") ;
ShellExecute(h,"open","C://simple.html",
NULL,NULL,SW_SHOWNORMAL);
}
//关闭IE及其它应用
void CloseIE()
{
int app=BSM_APPLICATIONS;
unsigned long bsm_app=(unsigned long )app;
BroadcastSystemMessage(BSF_POSTMESSAGE,&bsm_app,
WM_CLOSE,NULL,NULL);
}
2. 如何给树控件加入工具提示
l 首先给树控件加入TVS_INFOTIP属性风格，如下所示：
if (!m_ctrlTree.Create(WS_CHILD|WS_VISIBLE|
TVS_HASLINES|TVS_HASBUTTONS|TVS_LINESATROOT|TVS_SHOWSELALWAYS|TVS_INFOTIP, //加入提示TVS_INFOTIP，jingzhou xu(树控件ID:100)
CRect(0, 0, 0, 0), &m_wndTreeBar, 100))
{
TRACE0("Failed to create instant bar child/n");
return -1;
}
l 其次加入映射消息声明，如下所示:
afx_msg void OnGetInfoTip(NMHDR* pNMHDR,LRESULT* pResult); //树控件上加入提示消息，jingzhou xu
ON_NOTIFY(TVN_GETINFOTIP, 100, OnGetInfoTip) //树控件条目上加入提示，jingzhou xu
l 最后加入呼应涵数处理：
void CCreateTreeDlg::OnGetInfoTip(NMHDR* pNMHDR,
LRESULT* pResult)
{
*pResult = 0;
NMTVGETINFOTIP* pTVTipInfo = (NMTVGETINFOTIP*)pNMHDR;
LPARAM itemData = (DWORD) pTVTipInfo->lParam;
//对应每个条目的数据
HTREEITEM hItem = pTVTipInfo->hItem;
CString tip;
HTREEITEM hRootItem = m_chassisTree.GetRootItem();
if (hRootItem != pTVTipInfo->hItem)
{
tip = "树结点的提示";
}
else
{
tip = "树根上的提示";
}
strcpy(pTVTipInfo->pszText, (LPCTSTR) tip);
}
3. 如何获取系统信息框的路径
#include <atlbase.h>
#define IDS_REG_KEY_MSINFO_PATH1 _T( "Software//Microsoft//Shared Tools//MSInfo" )
#define IDS_REG_KEY_MSINFO_PATH2 _T( "Software//Microsoft//Shared Tools Location" )
#define IDS_REG_VAL_MSINFO_PATH1 _T( "Path" )
#define IDS_REG_VAL_MSINFO_PATH2 _T( "MSInfo" )
#define IDS_MSINFO_EXE_NAME _T( "MSInfo32.exe" )
//...
BOOL GetSysInfoPath( CString& strPath )
{
strPath.Empty();
LPTSTR pszPath = strPath.GetBuffer( MAX_PATH );
CRegKey reg;
DWORD dwSize = MAX_PATH;
LONG nRet = reg.Open( HKEY_LOCAL_MACHINE, IDS_REG_KEY_MSINFO_PATH1, KEY_READ );
// 在注册表中寻找第一个"MSInfo32.exe" 位置
if ( nRet == ERROR_SUCCESS )
{
#if ( _MFC_VER >= 0x0700 )
nRet = reg.QueryStringValue( IDS_REG_VAL_MSINFO_PATH1, pszPath, &dwSize );
#else
nRet = reg.QueryValue( pszPath, IDS_REG_VAL_MSINFO_PATH1, &dwSize );
#endif
reg.Close();
}
// 如果第一次寻找失败，则进行第二次寻找
if ( nRet != ERROR_SUCCESS )
{
nRet = reg.Open( HKEY_LOCAL_MACHINE, IDS_REG_KEY_MSINFO_PATH2, KEY_READ );
if ( nRet == ERROR_SUCCESS )
{
#if ( _MFC_VER >= 0x0700 )
reg.QueryStringValue( IDS_REG_VAL_MSINFO_PATH2, pszPath, &dwSize );
#else
reg.QueryValue( pszPath, IDS_REG_VAL_MSINFO_PATH2, &dwSize );
#endif
// 路径名不包括EXE文件名
if ( nRet == ERROR_SUCCESS )
VERIFY( ::PathAppend( pszPath, IDS_MSINFO_EXE_NAME ) );
reg.Close();
}
}
strPath.ReleaseBuffer();
strPath.FreeExtra();
// 检查文件是否有效.
return ::PathFileExists( strPath );
}
4. 如何直接运行一个资源中的程序
bool Run()
{
CFile f;
char* pFileName = "Execution.exe";
if( !f.Open( pFileName, CFile::modeCreate | CFile::modeWrite, NULL ) )
{
AfxMessageBox("Can not create file!");
return 0;
}
CString path = f.GetFilePath();
HGLOBAL hRes;
HRSRC hResInfo;
//获取应用实例
HINSTANCE insApp = AfxGetInstanceHandle();
//寻找EXE资源名
hResInfo = FindResource(insApp,(LPCSTR)IDR_EXE4,"EXE");
hRes = LoadResource(insApp,hResInfo ); // Load it
DWORD dFileLength = SizeofResource( insApp, hResInfo ); //计算EXE文件大小
f.WriteHuge((LPSTR)hRes,dFileLength); //写入临时文件
f.Close();
HINSTANCE HINSsd = ShellExecute(NULL, "open",path, NULL, NULL, SW_SHOWNORMAL);> //运行它.
return 1;
}
5. 如何遍历整个目录
#include <windows.h>
#include <shlobj.h>
//浏览目录.
void BrowseFolder( void )
{
TCHAR path[MAX_PATH];
BROWSEINFO bi = { 0 };
bi.lpszTitle = ("递归调用所有目录");
LPITEMIDLIST pidl = SHBrowseForFolder ( &bi );
if ( pidl != 0 )
{
// 获取目录路径
SHGetPathFromIDList ( pidl, path );
//设置为当前路径
SetCurrentDirectory ( path );
//搜索所有子目录
SearchFolder( path );
// 释放内存
IMalloc * imalloc = 0;
if ( SUCCEEDED( SHGetMalloc ( &imalloc )) )
{
imalloc->Free ( pidl );
imalloc->Release ( );
}
}
//搜索其下所有子目录及文件.
void SearchFolder( TCHAR * path )
{
WIN32_FIND_DATA FindFileData;
HANDLE hFind;
TCHAR filename[ MAX_PATH + 256 ];
TCHAR pathbak[ MAX_PATH ];
//复制初始用户选择目录
strcpy( pathbak, path );
//寻找第一个文件
hFind = FindFirstFile ( "*.*", &FindFileData );
//搜索所有文件及子目录
do
{
if ( hFind != INVALID_HANDLE_VALUE )
{
//如果是当前目录或父目录，跳过
if ( ! ( strcmp( FindFileData.cFileName, "." ) ) || ! ( strcmp( FindFileData.cFileName, ".." ) ) )
{
continue;
}
//恢复初始用户选择目录
strcpy( path, pathbak );
//列出所有发现的文件
sprintf( path, "%s//%s", path, FindFileData.cFileName );
//如果 SetCurrentDirectory 成功的话，则它是一个目录，递归调用继续搜索子目录
if ( ( SetCurrentDirectory( path ) ) )
{
SearchFolder( path );
}
//插入文件及路径名到列表框m_listbox_hwnd中
SendMessage( m_listbox_hwnd, LB_ADDSTRING, 0, path ); //<--INSERT WHAT YOU WANT DONE HERE!
}
}
while ( FindNextFile ( hFind, &FindFileData ) && hFind != INVALID_HANDLE_VALUE );
FindClose ( hFind );
}
6. 如何实现窗口到系统区图标间的动画效果
//********************************************************************************
//* 名称：FindTrayWnd
//* 作者：徐景周(jingzhou_xu@163.net)
//* 功能：在显示窗体动画效果前，先寻找系统区位置
//********************************************************************************
BOOL CALLBACK FindTrayWnd(HWND hwnd, LPARAM lParam)
{
TCHAR szClassName[256];
GetClassName(hwnd, szClassName, 255);
// 比较窗口类名
if (_tcscmp(szClassName, _T("TrayNotifyWnd")) == 0)
{
CRect *pRect = (CRect*) lParam;
::GetWindowRect(hwnd, pRect);
return TRUE;
}
// 当找到时钟窗口时表示可以结束了
if (_tcscmp(szClassName, _T("TrayClockWClass")) == 0)
{
CRect *pRect = (CRect*) lParam;
CRect rectClock;
::GetWindowRect(hwnd, rectClock);
pRect->right = rectClock.left;
return FALSE;
}
return TRUE;
}
//********************************************************************************
//* 名称：WinAnimation
//* 作者：徐景周(jingzhou_xu@163.net)
//* 功能：显示窗口动画效果的涵数
//********************************************************************************
void CScreenSnapDlg::WinAnimation(BOOL ShowFlag)
{
CRect rect(0,0,0,0);
// 查找托盘窗口
CWnd* pWnd = FindWindow("Shell_TrayWnd", NULL);
if (pWnd)
{
pWnd->GetWindowRect(rect);
EnumChildWindows(pWnd->m_hWnd, FindTrayWnd, (LPARAM)&rect);
//rect 为托盘区矩形
CRect rcWnd;
GetWindowRect(rcWnd);
if(ShowFlag) //窗体滑向系统区
DrawAnimatedRects(GetSafeHwnd(),IDANI_CAPTION,rcWnd,rect);
else //窗体从系统区滑出
DrawAnimatedRects(GetSafeHwnd(),IDANI_CAPTION,rect,rcWnd);
}
}
用法如下：
if(IsWindowVisible()) //窗体是否已隐藏
{
ShowWindow(SW_HIDE); //先隐藏窗体
WinAnimation(true); //窗体动画滑入到系统区中
}
else
{
WinAnimation(false); //窗体动画从系统区滑出
ShowWindow(SW_SHOW);
}
