一、C++函数(成功的dll注入函数)
BOOL inject_dll( const char *dll_path, const DWORD remote_pro_id )
{
HANDLE h_token;
if ( OpenProcessToken( GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES, &h_token ) )
{
TOKEN_PRIVILEGES tkp;
//修改进程权限
LookupPrivilegeValue( NULL,SE_DEBUG_NAME, &tkp.Privileges[0].Luid );
tkp.PrivilegeCount = 1;
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
//通知系统修改进程权限
AdjustTokenPrivileges( h_token, FALSE, &tkp, sizeof( tkp ), NULL, NULL );
}
HANDLE h_remote_process;
//打开远程线程
if( ( h_remote_process = OpenProcess( PROCESS_CREATE_THREAD | //允许远程创建线程
PROCESS_VM_OPERATION | //允许远程VM操作
PROCESS_VM_WRITE, //允许远程VM写
FALSE, remote_pro_id ) )== NULL )
{
//AfxMessageBox("OpenProcess Error!");
return FALSE;
}
char *lib_func_buf;
//在远程进程的内存地址空间分配DLL文件名缓冲区
lib_func_buf = (char *) VirtualAllocEx( h_remote_process, NULL, lstrlen(dll_path) + 1,
MEM_COMMIT, PAGE_READWRITE);
if( lib_func_buf == NULL )
{
//AfxMessageBox("VirtualAllocEx error! ");
return FALSE;
}
//将DLL的路径名复制到远程进程的内存空间
if( WriteProcessMemory( h_remote_process,
lib_func_buf, ( void * )dll_path, lstrlen( dll_path ) + 1, NULL ) == 0 )
{
//AfxMessageBox("WriteProcessMemory Error");
return FALSE;
}
//计算LoadLibraryA的入口地址
PTHREAD_START_ROUTINE load_start_addr = ( PTHREAD_START_ROUTINE )
GetProcAddress( GetModuleHandle( TEXT("Kernel32") ), "LoadLibraryA");
if( load_start_addr == NULL )
{
//AfxMessageBox("GetProcAddress Error");
return FALSE;
}
HANDLE h_remote_thread;
if( (h_remote_thread = CreateRemoteThread( h_remote_process, NULL, 0,
load_start_addr, lib_func_buf, 0, NULL ) ) == NULL)
{
//AfxMessageBox("CreateRemoteThread Error");
return FALSE;
}
return TRUE;
}
二、NumberEdit控件，能设定小数位和整数位
实现代码如下：
//NumberEdit.h
#ifndef __NUMBEREDIT_H__
#define __NUMBEREDIT_H__
class CNumberEdit : public CEdit
{
public:
CNumberEdit();
virtual ~CNumberEdit();
void SetAfterDotLen(UINT iAfterDotLen){m_iAfterDotLen =iAfterDotLen;}
UINT GetAfterDotLen(){return m_iAfterDotLen;}
void SetAfterIntLen(UINT iAfterIntLen){m_iAfterIntLen =iAfterIntLen;}
UINT GetAfterIntLen(){return m_iAfterIntLen;}
protected:
BOOL CheckNumber(UINT nChar,UINT nRepCnt,UINT nFlags);
//BOOL CheckOnePlus(UINT nChar,UINT nRepCnt,UINT nFlags);
BOOL CheckOneMinus(UINT nChar,UINT nRepCnt,UINT nFlags);
BOOL CheckOneDot(UINT nChar,UINT nRepCnt,UINT nFlags);
int GetCaretXPos();
CString m_str;
UINT m_iAfterDotLen;
UINT m_iAfterIntLen;

//{{AFX_MSG(CUntcNumberEdit)
afx_msg void OnChar(UINT nChar, UINT nRepCnt, UINT nFlags);

};
#endif

}

{
}
BEGIN_MESSAGE_MAP(CNumberEdit, CEdit)
//{{AFX_MSG_MAP(CNumberEdit)

END_MESSAGE_MAP()
void CNumberEdit::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
// TODO: Add your message handler code here and/or call default
if(nChar == 8)
{
CEdit::OnChar(nChar, nRepCnt, nFlags);
return;
}
BOOL bChange = FALSE;
GetWindowText(m_str);
if(CheckNumber(nChar,nRepCnt,nFlags))
{
bChange = TRUE;
}
//else if(CheckOnePlus(nChar,nRepCnt,nFlags))
//{
// ;//do nothing
//}
else if(CheckOneMinus(nChar,nRepCnt,nFlags))
{
bChange = TRUE;
}
else if(CheckOneDot(nChar,nRepCnt,nFlags))
{

}
if(bChange)
{

//SetFormatText();

}
}

{

{

}

}
else
{

if(iDotPos == 0)
m_str = "0"+ m_str;
else if(iDotPos <0)

}

{
return FALSE;
}
}

if (iIntLen>=(int)m_iAfterIntLen)
{
return FALSE;
}
}
else
{

}
return TRUE;
}
