VBA中的UIToolControl1_MouseDown

<P>VBA中的UIToolControl1_MouseDown在VB中对应着什么?应该用什么来表示UIToolControl1_MouseDown?</P>

我试了,onclick之类的到是可以实现,可<STRONG>UIToolControl1_MouseDown</STRONG><BR>对应的操作我还是不能实现.

<P>感谢感谢,大家一起学习一起进步</P>

<P> 随便用什么来表示,你可以表示为一切vb里面可能发生的动作,只要你需要</P>

呵呵，自己也是在和你的交流中得到进步，话语有不得体的地方，还请见谅

<P>初学者,请楼上见谅</P>

<P>YourTool：改成类模块的名字啊</P>
<P>'As后没有MapControl：难道你的VB程序里没有使用MapControl，当然如果你使用了PageLayoutControl，那请改成PageLayoutControl。</P>

<P>不好意思,还是运行不了</P>
<P>Dim pCom As ICommand</P>
<P>Set pCom = New YourTool   ’YourTool Implements esriSystemUI.ICommand and  esriSystemUI.ITool <BR>pCom.OnCreate (mapCtrl.object)<BR>pCom.OnClick<BR>If TypeOf pCom Is esriSystemUI.ITool Then<BR>    Set mapCtrl.CurrentTool = pCom<BR>End If</P>
<P>其中的Set pCom = New YourTool   ’YourTool 是什么?</P>
<P>还有Dim m_mapctrl As MapControl   'As后没有MapControl</P>

<P>你的意思是把VBA中的UITool实现的功能转成VB来实现？</P>
<P>如果是这样的话</P>
<P>我建议你：</P>
<P>1、首先把你在UIToolControl1中的代码，移植到一个实现 esriSystemUI.ICommand and  esriSystemUI.ITool这两个的接口的一个类模块</P>
<P>例如Identify：</P>
<P>Implements esriSystemUI.ICommand<BR>Implements esriSystemUI.ITool<BR>Dim m_mapctrl As MapControl       'ArcMap application<BR> <BR>Private Property Get ICommand_Enabled() As Boolean<BR>    <BR>    ' TOD Add your implementation here<BR>    ' ICommand_Enabled =<BR>    <BR>End Property<BR> <BR>Private Property Get ICommand_Checked() As Boolean<BR>    <BR>    ' TOD Add your implementation here<BR>    ' ICommand_Checked =<BR>    <BR>End Property<BR> <BR>Private Property Get ICommand_Name() As String<BR>    <BR>    ' TOD Add your implementation here<BR>     ICommand_Name = "IdentifyTool"<BR>    <BR>End Property<BR> <BR>Private Property Get ICommand_Caption() As String<BR>    <BR>    ' TOD Add your implementation here<BR>     ICommand_Caption = "IdentifyTool"<BR>    <BR>End Property<BR> <BR>Private Property Get ICommand_Tooltip() As String<BR>    <BR>    ' TOD Add your implementation here<BR>    ' ICommand_Tooltip =<BR>    <BR>End Property<BR> <BR>Private Property Get ICommand_Message() As String<BR>    <BR>    ' TOD Add your implementation here<BR>    ' ICommand_Message =<BR>    <BR>End Property<BR> <BR>Private Property Get ICommand_HelpFile() As String<BR>    <BR>    ' TOD Add your implementation here<BR>    ' ICommand_HelpFile =<BR>    <BR>End Property<BR> <BR>Private Property Get ICommand_HelpContextID() As Long<BR>    <BR>    ' TOD Add your implementation here<BR>    ' ICommand_HelpContextID =<BR>    <BR>End Property<BR> <BR>Private Property Get ICommand_Bitmap() As esriSystem.OLE_HANDLE<BR>    <BR>    ' TOD Add your implementation here<BR>    ' ICommand_Bitmap =<BR>    <BR>End Property<BR> <BR>Private Property Get ICommand_Category() As String<BR>    <BR>    ' TOD Add your implementation here<BR>    ' ICommand_Category =<BR>    <BR>End Property<BR> <BR>Private Sub ICommand_OnCreate(ByVal hook As Object)<BR>    <BR>    ' TOD Add your implementation here<BR>    Set m_mapctrl = gfrmMap.mapCtrl<BR>    'Set m_mapctrl.object = hook<BR>End Sub<BR> <BR>Private Sub ICommand_OnClick()<BR>    <BR>    ' TOD Add your implementation here<BR>    <BR>End Sub<BR> <BR>Private Property Get ITool_Cursor() As esriSystem.OLE_HANDLE<BR>    <BR>    ' TOD Add your implementation here<BR>    ' ITool_Cursor =<BR>    <BR>End Property<BR> <BR>Private Sub ITool_OnMouseDown(ByVal Button As Long, ByVal shift As Long, ByVal x As Long, ByVal y As Long)<BR>    <BR>    ' TOD Add your implementation here<BR>  <BR>  Dim pActiveView As IActiveView<BR>  Dim pIdentifyDialog As IIdentifyDialog<BR>  Dim pIdentifyDialogProps As IIdentifyDialogProps<BR>  Dim pEnumLayer As IEnumLayer<BR>  Dim pLayer As ILayer</P>

<P>  'Create a new IdentifyDialog and associate it<BR>  'with the focus map and the map's display<BR>  Set pIdentifyDialog = New IdentifyDialog<BR>  Set pIdentifyDialogProps = pIdentifyDialog 'QI<BR>  Set pIdentifyDialog.Map = m_mapctrl.Map<BR>  Set pIdentifyDialog.Display = pActiveView.ScreenDisplay<BR>  <BR>  'Clear the dialog on each mouse click<BR>  pIdentifyDialog.ClearLayers<BR>  <BR>  'Perform an identify on all of the layers the dialog<BR>  'says are searchable<BR>  Set pEnumLayer = pIdentifyDialogProps.Layers<BR>  pEnumLayer.Reset<BR>  Set pLayer = pEnumLayer.Next<BR>  Do While Not pLayer Is Nothing<BR>    pIdentifyDialog.AddLayerIdentifyPoint pLayer, x, y<BR>    Set pLayer = pEnumLayer.Next<BR>  Loop<BR>  <BR>  pIdentifyDialog.Show</P>
<P>End Sub<BR> <BR>Private Sub ITool_OnMouseMove(ByVal Button As Long, ByVal shift As Long, ByVal x As Long, ByVal y As Long)<BR>    <BR>    ' TOD Add your implementation here<BR>    <BR>End Sub<BR> <BR>Private Sub ITool_OnMouseUp(ByVal Button As Long, ByVal shift As Long, ByVal x As Long, ByVal y As Long)<BR>    <BR>    ' TOD Add your implementation here<BR>    <BR>End Sub<BR> <BR>Private Sub ITool_OnDblClick()<BR>    <BR>    ' TOD Add your implementation here<BR>    <BR>End Sub<BR> <BR>Private Sub ITool_OnKeyDown(ByVal keyCode As Long, ByVal shift As Long)<BR>    <BR>    ' TOD Add your implementation here<BR>    <BR>End Sub<BR> <BR>Private Sub ITool_OnKeyUp(ByVal keyCode As Long, ByVal shift As Long)<BR>    <BR>    ' TOD Add your implementation here<BR>    <BR>End Sub<BR> <BR>Private Function ITool_OnContextMenu(ByVal x As Long, ByVal y As Long) As Boolean<BR>    <BR>    ' TOD Add your implementation here<BR>    <BR>End Function<BR> <BR>Private Sub ITool_Refresh(ByVal hdc As esriSystem.OLE_HANDLE)</P>
<P>    ' TOD Add your implementation here</P>
<P>End Sub<BR> <BR>Private Function ITool_Deactivate() As Boolean<BR>    <BR>    ' TOD Add your implementation here<BR>    ITool_Deactivate = True<BR>End Function<BR></P>
<P>其实以上很多代码都是由Add-ins中的ESRI InterFace Implementer这一工具直接生成的，真正要写的代码主要是ITool_OnMouseDown事件中，这就是你的UITool MouseDown实现的功能。</P>
<P>2、然后就像我上一贴那样使用你的类模块</P>

能不能具体点,我还不太明白<img src="images/post/smile/dvbbs/em12.gif" />
