<br>主题：如何在对话框上加载自制工具栏？谢谢
<br>内容：请教高手：<BR>&nbsp;&nbsp;&nbsp;&nbsp;我想在一个菜单项中弹出的对话框中加载自制的工具栏，可是显示对话框却没有工具栏。代码如下：<BR><BR>if (!m_Bar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP| CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) ||<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;!m_Bar.LoadToolBar(IDR_BAR1))<BR>&nbsp;&nbsp;&nbsp;&nbsp;{<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TRACE0(&#34;Failed to create toolbar\n&#34;);<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return -1;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// fail to create<BR>}<BR><BR>为何呢？是否还要重画工具栏呢？怎么做呢？谢谢高手。

<br>内容：在 OnInitDialog 中加入下面代码：<BR><BR>&nbsp;&nbsp;BOOL CYourDlg::OnInitDialog()<BR>&nbsp;&nbsp;{<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; CDialog::OnInitDialog();&nbsp;&nbsp;&nbsp;&nbsp;<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Create the toolbar.

<br>内容：由于工具条是动态加入的，其位置可能与原来对话框中控件冲突，因此在加入工具条后应该计算出加入工具条后剩余的用户区部分，并移动对话框中原有控件的位置。<BR><BR>CRect rcClientStart;//用于存放整个用户区<BR>CRect rcClientNow;//用于存放加入工具条后剩余的用户区<BR>GetClientRect(rcClientStart);//取得整个用户区并存放到<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //rcClientStart中<BR>//下面这个函数计算出加入工具条后剩余的用户区，并存放到<BR>//rcClientNow中,参考MSDN<BR>RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST,0, reposQuery, rcClientNow);<BR>&nbsp;&nbsp;&nbsp;&nbsp; <BR><BR>
