===========================================================
//注意事项
//先执行OnInitDialog()函数，然后执行构造函数! 
//98下没有新宋体 
//XP下窗口高度加8 
===========================================================
………1,滚动条处理方法
//1,设置范围 
m_spscroll.SetScrollRange(0,200); 
SCROLLINFO si; 
si.cbSize=sizeof(SCROLLINFO); 
si.nPage=100; 
si.fMask=SIF_PAGE;//设置页宽 
m_spscroll.SetScrollInfo(&si); 
//2，处理消息，垂直滚动条加WM_VSCROLL消息，水平加WM_HSCROLL消息 
void CPrintView::OnVScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar) 
{ 
// TODO: Add your message handler code here and/or call default 
if(pScrollBar->GetDlgCtrlID()==IDC_SCROLLBAR1) 
{ 
int nCurrentPos=pScrollBar->GetScrollPos(); 
SCROLLINFO si; 
si.fMask=SIF_PAGE;//取得页宽 
pScrollBar->GetScrollInfo(&si); 
switch(nSBCode) 
{ 
case SB_THUMBTRACK://移动滑块 
case SB_THUMBPOSITION: 
pScrollBar->SetScrollPos(nPos); //设置页宽后滚动条的pos会以max/nPage倍数减少，所以在使用时注意把pos值*(max/nPage)能得到原值 
break; 
case SB_LINEUP://点向上小三角 
pScrollBar->SetScrollPos(nCurrentPos-1); 
break; 
case SB_LINEDOWN://点向下小三角 
pScrollBar->SetScrollPos(nCurrentPos+1); 
break; 
case SB_PAGEUP://向上一页 
pScrollBar->SetScrollPos(nCurrentPos-si.nPage); 
break; 
case SB_PAGEDOWN://向下一页 
pScrollBar->SetScrollPos(nCurrentPos+si.nPage); 
break; 
} 
} 
CDialog::OnVScroll(nSBCode, nPos, pScrollBar); {} 

………2,锁定鼠标
bool pOld; 
CRect rt; 
SetForegroundWindow(); 
SystemParametersInfo(SPI_SETSCREENSAVERRUNNING,true,&pOld,SPIF_UpdateINIFILE); 
GetWindowRect(rt); 
ClipCursor(rt); 
//加到 LRESULT CLockDlg::WindowProc(UINT message, WPARAM wParam, LPARAM lParam) 会有意外的效果

………3,在列表字符前插入一个负数字符以修改乱码
int index=m_list.GetSelectionMark();//在列表字符前插入一个负数字符以修改乱码 
CString cs; 
cs=m_list.GetItemText(index,0); 
char insert_char=-87; 
cs.Insert(0,insert_char); 
m_list.SetItemText(index,0,cs); 

………4,在列表中添加项目最大只能显示259个字符(不含'/0') 
int char_length=cs.GetLength();//cs,ct为CString类对象，是要发到列表框的文本但是可能大于259字节 
while(char_length>259)//如果大于259字节 
{ 
ct=cs.Left(259); 
m_list.InsertItem(0,ct);//在列表中添加项目最大只能显示259个字符(不含'/0') 
cs=cs.Right(char_length-259); 
char_length=cs.GetLength(); 
} 
m_list.InsertItem(0,cs);//在列表中添加项目最大只能显示259个字符(不含'/0') 

………5,设置NT窗口的透明度
OSVERSIONINFO osv; 
osv.dwOSVersionInfoSize=sizeof OSVERSIONINFO; 
GetVersionEx(&osv);//取得版本信息 
if(osv.dwPlatformId==VER_PLATFORM_WIN32_NT)//VER_PLATFORM_WIN32_WINDOWS 98 Me用这个宏 
{ 
//加入WS_EX_LAYERED扩展属性 
SetWindowLong(this->GetSafeHwnd(),GWL_EXSTYLE, 
GetWindowLong(this->GetSafeHwnd(),GWL_EXSTYLE)^0x80000);//如果多次调用下面这个函数设置，这个函数只在一个位置调用一次就行了 
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, 200,//0 ~ 2552); 
FreeLibrary(hInst); 
} 
} 

………6,字体对话框的初始化
LOGFONT lf; 
lf.lfHeight=-35; 
lf.lfCharSet=134; 
lf.lfWeight=400; 
lf.lfOutPrecision=3; 
lf.lfClipPrecision=2; 
lf.lfQuality=1; 
lf.lfPitchAndFamily=2; 
strcpy(lf.lfFaceName,"宋体");//以上初始化为宋体26号字 
CFontDialog cf(&lf);//字体 
cf.m_cf.rgbColors=textcolor;//颜色 

………7,移动没有标题的窗口
//1定义： 
CPoint just_point; 
//2 
void CClockfortecherDlg::OnLButtonDown(UINT nFlags, CPoint point) 
{ 
// TODO: Add your message handler code here and/or call default 
just_point=point; 
CDialog::OnLButtonDown(nFlags, point); 
} 
//3 
void CClockfortecherDlg::OnMouseMove(UINT nFlags, CPoint point) 
{ 
// TODO: Add your message handler code here and/or call default 
WINDOWPLACEMENT wi; 
GetWindowPlacement(&wi); 
if(nFlags==MK_LBUTTON) 
SetWindowPos(&wndTop,wi.rcNormalPosition.left+(point.x-just_point.x), wi.rcNormalPosition.top+(point.y-just_point.y), 
0,0,SWP_NOSIZE); 
CDialog::OnMouseMove(nFlags, point); 
} 

………8,线程与信号量
//1,定义信号量句柄 
HANDLE　event; 
//2,创建信号量 
event=CreateEvent(NULL, TRUE, FALSE, NULL); 
//3,创建线程: 
//1)定义线程函数，格式必须如下,其中lParam为AfxBeginThread的第二个参数值，可强制转化成所需类型 
UINT WorkThreadProc(LPVOID lParam)//必须是 UINT XXX..XXX(LPVOID lParam) 
{ 
//代码示例WaitForSingleObject： 
while(1) 
{
//注意，如果线程间要求同步或互斥的时候，要在每一层循环体中加入WaitForSingleObject 
WaitForSingleObject((HANDLE)lParam, INFINITE); 
//WaitForSingleObject的使用方法：第一个为信号量HANDLE，是CreateEvent的返回值,第二个参数为等待的毫秒数（1/1000秒） 
//第二个参数为INFINITE时则一直等待，直到调用SetEvent()设置信号量时函数返回；为数值（如1000）则函数在1秒后返回 
//（即使你没调用SetEvent()设置信号量） 
AfxMessageBox("fuck");//不能用MessageBox()因为这不是在类中了... 
ResetEvent((HANDLE)lParam); 
//重置信号量，以使WaitForSingleObject函数可以继续等待，否则（如果你已经调用过了SetEvent()设置了信号量） 
//WaitForSingleObject函数将会立刻返回 
} 
} 
//2)用AfxBeginThread创建一个WorkThreadProc的线程 
AfxBeginThread(WorkThreadProc,event); 
//4,在主程序需要的地方调用SetEvent()设置信号量启动线程 
SetEvent(event);//或者用WaitForMultipleObjects函数 
static UINT __stdcall WorkThreadProc(void* pThis);
//如果lParam参数为一个对话框的指针，想调用这个对话框的变量或函数那么就得这样定义线程函数，还要将WorkThreadProc改成//Wait_forDlg::WorkThreadProc，这样WorkThreadProc就成为CWait_forDlg类的函数，在这个线程里就可以调用该类的变量了，注意得用_beginthreadex函数创建线程
UINT CWait_forDlg::WorkThreadProc(void * lParam) 
{ 
CWait_forDlg *pThis=(CWait_forDlg *)lParam; 
HANDLE hObjects[2]; 
hObjects[0] = pThis->event1; 
hObjects[1]= pThis->event2; 
while(1) 
{ 
DWORD dwWait = WaitForMultipleObjects(2,hObjects,TRUE,INFINITE); 
//第一个参数为信号量个数2，第二个为指针，第三个如果为TRUE函数要等待两个信号量都被SetEvent才返回，返回值为最后一个
//SetEvent的WAIT_OBJECT_0+i；而为FALSE则只要有一个被SetEvent就返回，返回值为 WAIT_OBJECT_0+i 即信号量在数组中的位置 
//+WAIT_OBJECT_0 */ 
if (dwWait == WAIT_OBJECT_0) AfxMessageBox("fcuk 1 "); 
//开始ping 
if (dwWait == WAIT_OBJECT_0 + 1) 
AfxMessageBox("fcuk 2"); 
ResetEvent(hObjects[1]); 
ResetEvent(hObjects[0]); 
} 
}

_beginthreadex(NULL, 
0, 
WorkThreadProc,

0, 
0); 
//第三种创建线程的方法： 
HANDLE thread; 
DWORD threadrid; //线程ID 
DWORD WINAPI sniff(LPVOID no){} //线程函数这样定义 
thread=CreateThread(NULL, //安全属性 
0, //栈大小 
sniff, //要创建的线程名 
NULL, //参数（一般为调用线程的指针） 
0, //创建标志 
&threadrid); //线程ID 
CloseHandle(thread); 
………9,操作数据库ODBC
//在stdafx.h中加入 #include <afxdb.h> 
//1，用类向导，建立基于CRecordset或CDaoRecordset的新子类,并选择数据源m_setComplete 
//2，添加 
if ( ! m_setComplete . IsOpen () ) // if the recordset isn't already open.. 
m_setComplete . Open (); // open it

//3,修改

SWP_DRAWFRAME Draws a frame, defined in the class description of the window, around the window. 
SWP_FRAMECHANGED Sends a WM_NCCALCSIZE message to the window, even if the size of the window is not being changed. If this flag is not specified, WM_NCCALCSIZE is sent only when the size of the window is being changed. 
SWP_HIDEWINDOW Hides the window. 
SWP_NOACTIVATE Does not activate the window. If this flag is not set, the window is activated and moved to the top of either the topmost or nontopmost group, depending on the setting of the hWndInsertAfter parameter. 
SWP_NOMOVE Retains the current position and ignores the X and Y parameters. 
SWP_NOOWNERZORDER Does not change the position in the Z order of the owner window. 
SWP_NOREPOSITION Same as the SWP_NOOWNERZORDER flag. 
SWP_NOSIZE Retains the current size and ignores the cx and cy parameters. 
SWP_NOZORDER Retains the current Z order and ignores the hWndInsertAfter parameter. 
SWP_SHOWWINDOW Displays the window.
