在对话框中嵌入了一个CScrollView对象A，A可以响应鼠标按下操作，就是无法响应鼠标双击消息。请大侠帮忙看看为什么。

[schlafenhamster]

AfxMessageBox("鼠标按下");
改为:
afxDump << "鼠标按下\n";

[schlafenhamster]

我试了试：
// TODO: Add extra initialization here
m_pScrollView=new CMyScrollView;// 从CScrollView来
CRect rc;
GetClientRect(&rc);
rc.bottom -= 60;//保留OK CANCEL
m_pScrollView->Create(NULL, NULL, WS_VISIBLE | WS_CHILD, rc, this, 1000);

CSize sizeTotal;
sizeTotal.cx=800;
sizeTotal.cy=1000;
m_pScrollView->SetScrollSizes(MM_TEXT, sizeTotal);
m_pScrollView->ShowWindow(SW_SHOW);
//
void CMyScrollView::OnLButtonDown(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
afxDump << "LButtonDown\n";
CScrollView::OnLButtonDown(nFlags, point);
}

void CMyScrollView::OnLButtonDblClk(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
afxDump << "?????\n";

CScrollView::OnLButtonDblClk(nFlags, point);
}
//没问题

没看出问题，OnMouseActivate()是你加进去的吧。

[zm1824]

恩，是自己加的。问题解决了，谢谢各位。
原因如下：
BOOL CFcModelView::PreCreateWindow(CREATESTRUCT& cs)
{

HBRUSH hbkbrush = CreateSolidBrush(RGB(0, 0, 0));
LPCSTR lpMyOwnClass = AfxRegisterWndClass(CS_HREDRAW|CS_VREDRAW|CS_OWNDC, 0, hbkbrush);
cs.lpszClass = lpMyOwnClass;
return CView::PreCreateWindow( cs );
}

应该为:AfxRegisterWndClass(CS_HREDRAW|CS_VREDRAW|CS_OWNDC|CS_DBLCLKS, 0, hbkbrush);

[zm1824]

谢谢各位，特别是schlafenhamster...

[zm1824]

谢谢schlafenhamster，不过我按你的方法试了，还是不行，依然没有响应。

[schlafenhamster]

看看你的CFcModelView::的头文件行吗？

[Eleven]

WM_LBUTTONDDBLCLK消息
Double-clicking the left mouse button actually generates four events: WM_LBUTTONDOWN, WM_LBUTTONUP messages, the WM_LBUTTONDBLCLK call, and another WM_LBUTTONUP message when the button is released.
删除你WM_LBUTTONDOWN里的AfxMessageBox就可以了

[zm1824]

这个是头文件的情况。
FcModelView.h

#include <cmath>
#include "FR1AdminDoc.h"
#include "FcModel.h"

class CFcModelingNewDlg;

FcModelView.cpp

#include "stdafx.h"
#include "afxdlgs.h"
#include "FR1Admin.h"
#include "FcModelView.h"

FcModelingNewDlg.h

CFcModelView * m_pModelView;

[schlafenhamster]

我要看"FcModelView.h"
