关于 被0除 异常的捕获！
默认情况下，系统屏蔽了浮点数/整数运算时的异常错误，并以0或者无穷大表示结果，并不会产生异常。
这些数值计算异常列表如下：
_EM_INVALID
_EM_DENORMAL
_EM_ZERODIVIDE
_EM_OVERFLOW
_EM_UNDERFLOW
_EM_INEXACT
为了捕获上述异常，必须使用 _controlfp(...)/_control87(...) 运行库函数设置相关的屏蔽位，代码示例如下：
// ZeroDivide.cpp : By YangTze!
//
#include "stdafx.h"
#include <WINDOWS.H>
#include <STDIO.H>
#include <FLOAT.H>
void TestFunc()
{
int i = 888;
int j = 0;
__try {
i = i/j;
}
__except( GetExceptionCode() == EXCEPTION_INT_DIVIDE_BY_ZERO ? EXCEPTION_EXECUTE_HANDLER : EXCEPTION_CONTINUE_SEARCH ) {
MessageBox( NULL,"EXCEPTION_INT_DIVIDE_BY_ZERO!","Error!",MB_OK );
}
}
int _tmain(int argc, _TCHAR* argv[])
{
unsigned int nOldMask;
unsigned int nNewMask;
nOldMask = _controlfp( 0,0 );
nNewMask = ( ( nOldMask & ~_EM_ZERODIVIDE ) | ( _EM_ZERODIVIDE & _MCW_EM ) );
_controlfp( nNewMask,_MCW_EM );
TestFunc();
_controlfp( _CW_DEFAULT, 0xfffff );
return 0;
}
程序隐藏 之 运行时更改名字
当一个程序正在运行时，Windows 系统是不允许把它删除的，但在 Windows 2000/XP 中，当一个程序正在运行时，可以将它本身在相同磁盘分区内重命名和移动位置！
试想想：如果我们的程序一运行，就把自己移动位置并且换个名字，此时，Windows 任务管理器还显示的是原来的名字，嘿嘿，程序不见了（只有你知道哦）...
这种做法有什么用？嘿嘿，干坏事呗！
#include "stdafx.h"
#include <WINDOWS.H>
int _tmain(int argc, _TCHAR* argv[])
{
TCHAR szCurName[1024];
TCHAR szNewName[1024];
GetModuleFileName( NULL,szCurName,MAX_PATH );
_tcscpy( szNewName,szCurName );
_tcsupr( szNewName );
TCHAR *pPostfix = _tcsstr( szNewName,_T(".EXE") );
_tcscpy( pPostfix,_T("Renamed.EXE") );
MoveFile( szCurName,szNewName );
return 0;
}

用ITaskbarList接口操纵Windows任务栏程序按钮的状态
Step 1: 变量定义
class CXDlg : public CDialog
{
......
public:
typedef ITaskbarList *LPITaskbarList;
LPITaskbarList pTaskbar;
......
};
Step 2: 初始化 任务栏COM 对象
BOOL CXDlg::OnInitDialog()
{
......
// Initializes the Component Object Model(COM)
CoInitialize(0);
// We call below function since we only need to create one object
CoCreateInstance(
CLSID_TaskbarList,
0,
CLSCTX_INPROC_SERVER,
IID_ITaskbarList,
(void**)&pTaskbar
);
// Below function will initialize the taskbar list object
pTaskbar->HrInit();
......
}
Step 3: 使用：删除/显示 任务栏程序按钮
void CXDlg::OnBnClickedButtonHide()
{
pTaskbar->DeleteTab(this->GetSafeHwnd());
}
void CXDlg::OnBnClickedButtonShow()
{
pTaskbar->AddTab(this->GetSafeHwnd());
}
