GetWindowLong(hwnd, GWL_WNDPROC)

[fishion]

DWL_DLGPROC也看看

下面是一个edit 的子类化: m_hEdit=CreateEdit(hwnd); WNDPROC EdOldProc = (WNDPROC)SetWindowLong(m_hEdit, GWL_WNDPROC, (LONG)EDProc); SetProp(m_hEdit,// handle of window "EditOldProc", // atom or address of string EdOldProc);//

LRESULT CALLBACK EDProc(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam)
{// get oldproc
	WNDPROC OldEdProc=(WNDPROC)GetProp(hWnd,"EditOldProc");	
	char buf[100]= {0};
	switch(Msg)
    {
	case WM_NOTIFY:
//		OutputDebugString("notify\n");
		break;
	case WM_KEYUP:
//		OutputDebugString("WM_KEYUP\n");
		break;
	case WM_CHAR:
		if((TCHAR) wParam==VK_RETURN)
		{
			CallWindowProc(OldEdProc, hWnd, Msg, wParam, lParam);
			POINT pt;
			DWORD pos;
			int idx;
			// insert the indent 
			GetCaretPos(&pt);
			pos=SendMessage(hWnd,EM_CHARFROMPOS,0,MAKELPARAM(pt.x, pt.y));
			idx=LOWORD(pos);
			SendMessage(hWnd,EM_SETSEL,idx,idx);
			SendMessage(hWnd,EM_REPLACESEL,0,(LPARAM)"    ");
			return 0;
		}
		break;
#if 0
	case WM_PAINT:
		hdc=BeginPaint(hWnd,&ps);
// WS_BORDER 
		Rectangle(hdc,ps.rcPaint.left,ps.rcPaint.top,ps.rcPaint.right,ps.rcPaint.bottom);
// ES_MULTILINE	
		lines=SendMessage(hWnd,EM_GETLINECOUNT,0,0);
		for(jj=0;jj<lines;jj++)
		{// use GetWindowText will lost CR
			got=SendMessage(hWnd,EM_GETLINE,jj,(LPARAM)txt);
			txt[got]=0;
			if(jj==1)
			{
				SetTextColor(hdc,RGB(255,0,0));
				TextOut(hdc,2,2 + jj*16,txt,got);
			}
			else
			{
				SetTextColor(hdc,RGB(0,0,0));
				TextOut(hdc,2,2 + jj*16,txt,got);
			}
		}
		EndPaint(hWnd,&ps);
		return 0;
#endif
