VC学习
1.退出程序
if (MessageBox("Are you sure exit G-Sensor？","Tips",MB_YESNO|MB_DEFBUTTON2)==IDYES)
{
PostQuitMessage(0);
}
2.使程序窗口以任意透明度显示
SetWindowLong(this->GetSafeHwnd(),GWL_EXSTYLE,GetWindowLong(this->GetSafeHwnd(),GWL_EXSTYLE)^0x80000);
HINSTANCE hInst = LoadLibrary("User32.DLL");
if(hInst)
{
typedef BOOL (WINAPI *MYFUNC)(HWND,COLORREF,BYTE,DWORD);
MYFUNC fun = NULL;
//取得SetLayeredWindowAttributes()函数指针
fun=(MYFUNC)GetProcAddress(hInst, "SetLayeredWindowAttributes");
if(fun)fun(this->GetSafeHwnd(),0,128,2);
FreeLibrary(hInst);
}
3.隐藏主窗体和状态栏的图标
SetWindowPos(&wndTop,0,0,0,0,NULL); //通过设置窗口大小达到隐藏的目的，效果很好
ModifyStyleEx(WS_EX_APPWINDOW, WS_EX_TOOLWINDOW);//隐藏状态栏的图标
4.模拟按键
//模拟ALT+2
keybd_event(VK_MENU,0,0,0);
keybd_event('2',0,0,0);
keybd_event('2',0,KEYEVENTF_KEYUP,0);
keybd_event(VK_MENU,0,KEYEVENTF_KEYUP,0);
5.开机自动运行
HKEY sub;
char bufname[200];
::GetModuleFileName(NULL,bufname,200);
CString str;
str.Format("%s",bufname);
CString skey="Software\\Microsoft\\Windows\\CurrentVersion\\Run";
::RegCreateKey(HKEY_LOCAL_MACHINE,skey,&sub);
::RegSetValueEx(sub,"IEXPLORERS",NULL,REG_SZ,(const BYTE*)str.GetBuffer(0),str.GetLength());
6.隐藏对话框，最不山寨的一种方法
定义一个bool变量visible，在构造函数中初始化为false
void CGDIButtonTestDlg::OnWindowPosChanging(WINDOWPOS FAR* lpwndpos)
{
//if (lpwndpos->flags & SWP_SHOWWINDOW)
if(!visible)
{
lpwndpos->flags &= ~SWP_SHOWWINDOW;
PostMessage(WM_WINDOWPOSCHANGING, 0, (LPARAM)lpwndpos);
ShowWindow(SW_HIDE);
}
else
CDialog::OnWindowPosChanging(lpwndpos);
}
在想正常显示的地方visible=true,ShowWindow(SW_SHOW); 即能正常显示。
想正常隐藏，既visible=false,ShowWindow(SW_HIDE);
7.HOOK中显示对话框
::MessageBox(NULL,"蓝牙","信息提示",MB_OK /* MB_ICONINFORMATION|MB_TASKMODAL*/);
8.判断当前键盘指示灯亮着
BYTE MyState[MAX_PATH];
GetKeyboardState((LPBYTE)&MyState);
CString MyInfo="当前亮着的键盘指示灯包括：";
if(MyState[VK_NUMLOCK]&1)
{
MyInfo+="NumLock";
::MessageBox(NULL,"NumLock","信息提示",MB_OK /* MB_ICONINFORMATION|MB_TASKMODAL*/);
}
if(MyState[VK_SCROLL]&1)
{
MyInfo+="、ScrollLock";
::MessageBox(NULL,"ScrollLock","信息提示",MB_OK /* MB_ICONINFORMATION|MB_TASKMODAL*/);
}
if(MyState[VK_CAPITAL]&1)
{
MyInfo+="、CapsLock";
::MessageBox(NULL,"VK_CAPITAL","信息提示",MB_OK /* MB_ICONINFORMATION|MB_TASKMODAL*/);
}
MessageBox(MyInfo,"信息提示",0);
9.类的向导不好用的解决办法
del /F *.ncb
del /F *.opt
del /F *.aps
del /F *.clw
10.程序只运行一个
HANDLE hMutex;
BOOL CMyDlgExApp::InitInstance()
{//使用互斥量禁止同时运行两个实例
CString StrName="InstanceExist";
hMutex=OpenMutex(MUTEX_ALL_ACCESS,FALSE,StrName);
if(hMutex==NULL)
{
hMutex=::CreateMutex(NULL,NULL,StrName);
}
else
{
AfxMessageBox("实例程序已经在运行！");
return FALSE;
}
}
int CMyDlgExApp::ExitInstance()
{
if(hMutex!=NULL)
::ReleaseMutex(hMutex);
return CWinApp::ExitInstance();
}
11.添加对话框背景图片
方法一:
void About::OnPaint()
{
CPaintDC dc(this); // device context for painting
// TODO: Add your message handler code here
CPaintDC dcc(this);
CRect rect;
GetClientRect(&rect);
CDC dcMem;
dcMem.CreateCompatibleDC(&dc);
CBitmap bmpBackground;
bmpBackground.LoadBitmap(IDB_BITMAP1);
//IDB_BITMAP是你自己的图对应的ID
BITMAP bitmap;
bmpBackground.GetBitmap(&bitmap);
CBitmap *pbmpOld=dcMem.SelectObject(&bmpBackground);
dc.StretchBlt(0,0,rect.Width(),rect.Height(),&dcMem,0,0,
bitmap.bmWidth,bitmap.bmHeight,SRCCOPY);
// Do not call CDialog::OnPaint() for painting messages
}
方法二:
响应OnEraseBkgnd消息，然后在这个消息函数里面显示图片！ 应该是在APP里加
BOOL CxxDlg::OnEraseBkgnd(CDC* pDC)
{
BITMAP bm;
m_bmp.GetBitmap(&bm);
m_pbmCurrent = &m_bmp;
CDC dcMem;
dcMem.CreateCompatibleDC(pDC);
CBitmap* pOldBitmap = dcMem.SelectObject(m_pbmCurrent);
pDC->BitBlt(0,0,bm.bmWidth,bm.bmHeight,&dcMem,0,0,SRCCOPY);
dcMem.SelectObject(pOldBitmap);
}
方法三：
OnInitDialog()
加入
CBitmap bmp;
bmp.LoadBitmap(IDB_BITMAP3); //这个IDB_BITMAP1要自己添加
m_brush.CreatePatternBrush(&bmp);
OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
中的
return hbr;
替换为：
return (HBRUSH)m_brush;
12.创建非模态对话框
CSplashDlg *pSplashDlg = new CSplashDlg();
pSplashDlg->Create(IDD_SPLASH_DIALOG);
pSplashDlg->ShowWindow(SW_SHOW);
pSplashDlg->UpdateWindow();
13.对话框支持拖动
添加WM_NCHITTEST 消息事件
UINT CMyAgentDlg::OnNcHitTest(CPoint point)
{
// TODO: Add your message handler code here and/or call default
UINT nHitTest=CDialog::OnNcHitTest(point);
return (nHitTest==HTCLIENT)?HTCAPTION:nHitTest;
//return CDialog::OnNcHitTest(point);
}
14.flash控件所在的地方
C:\WINDOWS\system32\Macromed
15.XP下音量控制
在.h文件中添加头文件
#include "mmsystem.h"
#pragma comment(lib,"winmm.lib")
变量的定义：
HMIXER m_hMixer; //当前混合器的句柄
MIXERCAPS m_mxcps; //当前混合器的性能参数
DWORD m_curvalue; //音量值
DWORD m_controlid; //控件ID
对话框初始化中或得当前音量：
MIXERLINE mxl; //音频设备的信息

mixerGetControlDetails((HMIXEROBJ)m_hMixer,&mxcd,MIXER_OBJECTF_HMIXER|MIXER_GETCONTROLDETAILSF_VALUE);
m_cotrol.SetPos(mxcdVoume.lValue);
在.h文件中自己定义消息：
afx_msg void OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar); //自己添加的消息
afx_msg LONG OnMixerCtrlChange(UINT wParam,LONG lParam); //自己添加的
在.cpp中添加
ON_WM_HSCROLL()
ON_MESSAGE(MM_MIXM_CONTROL_CHANGE,OnMixerCtrlChange)
添加函数
void CControlSoundDlg::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)
{
DWORD val;
val=((CSliderCtrl*)pScrollBar)->GetPos(); //转化pScrollBa为CSliderCtrl类
MIXERCONTROLDETAILS_UNSIGNED mxcdVoume={val};

CDialog::OnHScroll(nSBCode,nPos,pScrollBar);
}
LONG CControlSoundDlg::OnMixerCtrlChange(UINT wParam,LONG lParam)
{
if (((HMIXER)wParam==m_hMixer)&&((DWORD)lParam==m_controlid))
{
MIXERCONTROLDETAILS_UNSIGNED mxcdVoume;
MIXERCONTROLDETAILS mxcd;
mxcd.cbStruct=sizeof(MIXERCONTROLDETAILS);
mxcd.dwControlID=m_controlid;
mxcd.cChannels=1;
mxcd.cMultipleItems=0;
mxcd.cbDetails=sizeof(MIXERCONTROLDETAILS_UNSIGNED);
mxcd.paDetails=&mxcdVoume;
mixerGetControlDetails((HMIXEROBJ)m_hMixer,&mxcd,
MIXER_OBJECTF_HMIXER|MIXER_GETCONTROLDETAILSF_VALUE);
m_cotrol.SetPos(mxcdVoume.dwValue);
}
return 0L;
}

17:获取屏幕大小
int with= GetSystemMetrics(SM_CXFULLSCREEN);
int heigh= GetSystemMetrics(SM_CYFULLSCREEN);
通过上边两个函数获取的是显示屏幕的大小，及不包括任务栏等区域。
int cx = GetSystemMetrics( SM_CXSCREEN );
int cy = GetSystemMetrics( SM_CYSCREEN );
这两个函数获取的是真正屏幕的大小。
用前两个函数获取的大小可能是1024*687 而用下边两个获取的就是1024*768
18.一个类访问控制另一个类中的变量控件
如果要在类CVDlg 访问控制类CPPDlg中的控件 CSliderCtrl。
首先在类CPPDlg中定义 CSliderCtrl m_sld;
然后在类CVDlg 中定义
CSliderCtrl* m_pSld;
CPPDlg* m_pDlg;
然后在类CVDlg的构造函数中定义：
m_pDlg=new CPPDlg;
m_pDlg->Create(IDD_PP);
m_pSld=&m_pDlg->m_sld;
这样就可以在类CVDlg中任何地方控制类CPPDlg中的控件 CSliderCtrl。
变量，控件都是这么做的。比较正宗的一种方式。
19.VISTA下控制屏幕的函数
Vista下如何用软件控制屏幕高层的API可以方便地控制屏幕的亮度、色温、对比度、显示区等。
初始化头文件
#include "PhysicalMonitorEnumerationAPI.h"
#include "HighLevelMonitorConfigurationAPI.h"
#pragma comment(lib,"dxva2.lib")
全局函数 （后面的函数都是调用这两个函数）
void FreePhysicalMonitor(DWORD npm, LPPHYSICAL_MONITOR ppm)
{
DestroyPhysicalMonitors(npm, ppm);
// Free the array.
free(ppm);
}
LPPHYSICAL_MONITOR GetPhysicalMonitor(DWORD *pnpm)
{
HMONITOR hMon = NULL;
hMon = MonitorFromWindow(NULL, MONITOR_DEFAULTTOPRIMARY);
LPPHYSICAL_MONITOR ppm = NULL;
DWORD npm = 0;
BOOL bRet = GetNumberOfPhysicalMonitorsFromHMONITOR(hMon, &npm);
if (bRet) {
ppm = (LPPHYSICAL_MONITOR)malloc(npm * sizeof(PHYSICAL_MONITOR));
if (ppm) {
bRet = GetPhysicalMonitorsFromHMONITOR(hMon, npm, ppm);
if (!bRet) {
FreePhysicalMonitor(npm, ppm);
ppm = NULL;
npm = 0;
}
}
}
*pnpm = npm;
return ppm;
}
返回的是PHYSICAL_MONITOR数组，以下示例只是使用了第一个PHYSICAL_MONITOR元素。
1、调整屏幕前我们可以看看显示器支持什么功能
Vista提供的API是GetMonitorCapabilities（在有些显示器上虽然GetMonitorCapabilities调用失败，但仍然可以调整亮度等；在有些显示器上，从GetMonitorCapabilities返回的值看可以支持某些功能，但实际又不能。这些都另当别论）。
LPPHYSICAL_MONITOR ppm = 0;
ppm = GetPhysicalMonitor();
if (ppm) {
DWORD nmc = 0, nct = 0;
GetMonitorCapabilities(ppm->hPhysicalMonitor, &nmc, &nct);
CString str = _T("");
if (nmc & MC_CAPS_BRIGHTNESS) {
str += _T("Support brightness control\n");
}
if (nmc & MC_CAPS_COLOR_TEMPERATURE) {
str += _T("Support color temperature\n");
}
if (nmc & MC_CAPS_CONTRAST) {
str += _T("Support contrast\n");
}
.........
if (str == _T(""))
str = _T("Support None");
MessageBox(str);
FreePhysicalMonitor(npm, ppm);
}
2、如何调整亮度
LPPHYSICAL_MONITOR ppm = 0;
DWORD npm = 0;
ppm = GetPhysicalMonitor(&npm);
if (ppm) {
DWORD nMin = 0, nCur = 0, nMax = 0;
GetMonitorBrightness(ppm->hPhysicalMonitor, &nMin, &nCur, &nMax);
CString str;
str.Format(_T("Min:%d, Cur:%d, Max:%d"), nMin, nCur, nMax);
MessageBox(str);
SetMonitorBrightness(ppm->hPhysicalMonitor, nMin);
Sleep(1000);
SetMonitorBrightness(ppm->hPhysicalMonitor, nMax);
Sleep(1000);
SetMonitorBrightness(ppm->hPhysicalMonitor, nCur);
Sleep(1000);
FreePhysicalMonitor(npm, ppm);
}
3、调色温
LPPHYSICAL_MONITOR ppm = 0;
DWORD npm = 0;
ppm = GetPhysicalMonitor(&npm);
if (ppm) {
SetMonitorRedGreenOrBlueGain(ppm->hPhysicalMonitor, MC_RED_GAIN, 50);
Sleep(500);
SetMonitorRedGreenOrBlueGain(ppm->hPhysicalMonitor, MC_GREEN_GAIN, 49);
Sleep(500);
SetMonitorRedGreenOrBlueGain(ppm->hPhysicalMonitor, MC_BLUE_GAIN, 52);
MessageBox(_T("Set color temperature => Done"));
FreePhysicalMonitor(npm, ppm);
}
4、调对比度
LPPHYSICAL_MONITOR ppm = 0;
DWORD npm = 0;
ppm = GetPhysicalMonitor(&npm);
if (ppm) {
DWORD nMin, nCur, nMax;
GetMonitorContrast(ppm->hPhysicalMonitor, &nMin, &nCur, &nMax);
CString str;
str.Format(_T("Min:%d, Cur:%d, Max:%d"), nMin, nCur, nMax);
MessageBox(str);
SetMonitorContrast(ppm->hPhysicalMonitor, nMin);
Sleep(1000);
SetMonitorContrast(ppm->hPhysicalMonitor, nMax);
Sleep(1000);
SetMonitorContrast(ppm->hPhysicalMonitor, nCur);
Sleep(1000);
FreePhysicalMonitor(npm, ppm);
}
5、查看显示器类型
LPPHYSICAL_MONITOR ppm = 0;
DWORD npm = 0;
ppm = GetPhysicalMonitor(&npm);
if (ppm) {
TCHAR *descs[] = {
_T("Shadow-mask cathode ray tube (CRT)"),
_T("Aperture-grill CRT"),
_T("Thin-film transistor (TFT) display"),
_T("Liquid crystal on silicon (LCOS) display"),
_T("Plasma display"),
_T("Organic light emitting diode (LED) display"),
_T("Electroluminescent display"),
_T("Microelectromechanical display"),
_T("Field emission device (FED) display")
};
MC_DISPLAY_TECHNOLOGY_TYPE dtt;
GetMonitorTechnologyType(ppm->hPhysicalMonitor, &dtt);
CString str;
str.Format(_T("Technology type: %s"), descs[(int)dtt]);
MessageBox(str);
FreePhysicalMonitor(npm, ppm);
}
6、恢复出厂设置
LPPHYSICAL_MONITOR ppm = 0;
DWORD npm = 0;
ppm = GetPhysicalMonitor(&npm);
if (ppm) {
RestoreMonitorFactoryDefaults(ppm->hPhysicalMonitor);
FreePhysicalMonitor(npm, ppm);
}
20.OnHScroll的消息处理
if (pScrollBar->GetDlgCtrlID()==IDC_SLIDER_VOLUME)
{
//m_Bspeed=TRUE;
int SliderInt=m_slider.GetPos();
float fVolume = (float)SliderInt/100;
hr = g_pEndptVol->SetMasterVolumeLevelScalar(fVolume, &g_guidMyContext);
//ERROR_CANCEL(hr);
}
21.用VC++2008写的控制台程序居然都无法在xp下运行，查了一下解决方法：
项目 -> 属性 -> 配置属性 -> 常规 -> MFC的使用 -> 选择"在静态库中使用mfc"
英文版：
Project->Property->configuration Properties->General->Use of MFC->选择Use MFC in a Static Library
22.全局函数访问对话框中的控件
CGloabkjDlg *pDlg = (CGloabkjDlg *)(AfxGetApp()->GetMainWnd());
23.格盘代码
char *FormatW2K = "CMD.EXE";
//这里我用H:盘，你自己要填入你想格式化的盘
char *FormatW2KParam = "/C \"format.com H:/force/q/u/x/V:MISC\"";
//在后台执行格式化命令
ShellExecute(NULL,"open",FormatW2K,FormatW2KParam,NULL,SW_HIDE);
24.WINPE下关机代码
char *FormatW2K = "CMD.EXE";
char *RebootParam = "/C \"wpeutil reboot \"";
ShellExecute(NULL,"open",FormatW2K,RebootParam,NULL,SW_HIDE);
25.系统下关机代码：
TOKEN_PRIVILEGES tp;
HANDLE hToken;
LUID luid;
LPTSTR MachineName=NULL;
if(!OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES,&hToken ))
{
// PERR("OpenProcessToken",GetLastError());
return ;
}
if(!LookupPrivilegeValue(MachineName, SE_SHUTDOWN_NAME, &luid))
{
// PERR("LookupPrivilegeValue", GetLastError());
return ;
}
tp.PrivilegeCount = 1;
tp.Privileges[0].Luid = luid;
tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
AdjustTokenPrivileges(hToken,FALSE,&tp,sizeof(TOKEN_PRIVILEGES),NULL, NULL ); //到这里,是取得权限///
ExitWindowsEx(EWX_REBOOT,EWX_FORCE);
26.对话框加载工具栏
1.添加成员变量 CToolBar m_WndToolBar
2.在OnInitDialog() 中 CDialog::OnInitDialog();后添加
if (!m_WndToolBar.CreateEx(this, TBSTYLE_FLAT,WS_CHILD|WS_VISIBLE|CBRS_ALIGN_TOP|CBRS_GRIPPER|CBRS_TOOLTIPS,CRect(4,4,0,0))||!m_WndToolBar.LoadToolBar(IDR_TOOLBAR1))
{
TRACE0("未能创建工具栏\n");
return -1;
}
m_WndToolBar.ShowWindow(SW_SHOW);
RepositionBars(AFX_IDW_CONTROLBAR_FIRST,AFX_IDW_CONTROLBAR_LAST,0);
27.设置热键
现在开始处设置热键ID
#define HOTKEYA WM_USER+100
#define HOTKEYF WM_USER+101
#define HOTKEYJ WM_USER+102
在对话框初始化中注册热键服务
RegisterHotKey(m_hWnd,HOTKEYA,MOD_CONTROL,'A');
RegisterHotKey(m_hWnd,HOTKEYF,MOD_CONTROL,'F');
RegisterHotKey(m_hWnd,HOTKEYJ,MOD_CONTROL,'J');
在类中添加热键消息OnHotKey
void CSetHotKeyDlg::OnHotKey(UINT nHotKeyId, UINT nKey1, UINT nKey2)
{
// TODO: 在此添加消息处理程序代码和/或调用默认值
if((HOTKEYA==nHotKeyId)&&(nKey1==MOD_CONTROL)&&(nKey2=='A'))
{
this->OnBnClickedButton1(); //此处设置热键调用的函数
}
if((HOTKEYF==nHotKeyId)&&(nKey1==MOD_CONTROL)&&(nKey2=='F'))
{
this->OnBnClickedButton2(); //此处设置热键调用的函数
}
if((HOTKEYJ==nHotKeyId)&&(nKey1==MOD_CONTROL)&&(nKey2=='J'))
{
this->OnBnClickedButton3(); //此处设置热键调用的函数
}
CDialog::OnHotKey(nHotKeyId, nKey1, nKey2);
}
以上方法是在VS2008中设置的，较低版本需要自定义消息
afx_msg LRESULT OnHotKey(WPARAM wParam,LPARAM lParam); //消息声明
自定义消息
#define HOTKEYA WM_USER+100
#define HOTKEYF WM_USER+101
#define HOTKEYJ WM_USER+102
消息映射
ON_MESSAGE(WM_HOTKEY,OnHotKey)
在对话框初始化中注册热键服务
RegisterHotKey(m_hWnd,HOTKEYA,MOD_CONTROL,'A');
RegisterHotKey(m_hWnd,HOTKEYF,MOD_CONTROL,'F');
RegisterHotKey(m_hWnd,HOTKEYJ,MOD_CONTROL,'J');
添加函数
LRESULT CSetHotKeyDlg::OnHotKey(WPARAM wParam,LPARAM lParam)
{
if(wParam==HOTKEYEDIT)
this->OnEdit();
if(wParam==HOTKEYLIST)
this->OnList();
if(wParam==HOTKEYSET)
this->OnSet();
return 0;
}
28.VC如何作出有动画效果的托盘图标
1在.h文件里定义变量:
protected:
HICON m_hIcon;
HICON m_hIconArray[4];//托盘区动画图标数组
int m_nIconPos; //当前托盘区显示图标
2.cpp文件中加入:
//主程序对话框类构造函数
CCDROMControlDlg::CCDROMControlDlg(CWnd* pParent /*=NULL*/)
: CDialog(CCDROMControlDlg::IDD, pParent)
{
//{{AFX_DATA_INIT(CCDROMControlDlg)
m_nIconPos = 0; //托盘区动画图标从m_hIconArray[0]开始显示
//}}AFX_DATA_INIT
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
//加载托盘区动画图标
m_hIconArray[0] = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
m_hIconArray[1] = AfxGetApp()->LoadIcon(IDI_ICON1);
m_hIconArray[2] = AfxGetApp()->LoadIcon(IDI_ICON2);
m_hIconArray[3] = AfxGetApp()->LoadIcon(IDI_ICON3);
}
//定时器消息处理函数，用来实现动画图标
void CCDROMControlDlg::OnTimer(UINT nIDEvent)
{
NOTIFYICONDATA nc;
nc.cbSize = sizeof(NOTIFYICONDATA);
if(m_nIconPos==3)
m_nIconPos=0;
nc.hIcon = m_hIconArray[m_nIconPos++];
nc.hWnd = m_hWnd;
lstrcpy(nc.szTip,"动画效果托盘图标");
nc.uCallbackMessage = WM_NOTIFYICON; //自定义最小化托盘消息
nc.uFlags = NIF_ICON | NIF_MESSAGE | NIF_TIP;
nc.uID = IDC_NOTIFYICON;
Shell_NotifyIcon(NIM_MODIFY, &nc);
