我的任务
分享提示变量没有定义是怎么回事？
我用了IEWebcontrol控件。代码如下：
//////////////////////////////////////////////////////////////////////
<%@ Page Language="VB" %>
<%@ Register TagPrefix="IE" Namespace="Microsoft.Web.UI.WebControls" Assembly="Microsoft.Web.UI.WebControls" %>
<%@ import Namespace="Microsoft.Web.UI.WebControls" %>
<script runat="server">
' Insert page code here
'
Sub Toolbar_ButtonClick( s As Object, e As EventArgs )
lblText.Text = txtSampleText.Text
Select Case chkgColor.SelectedCheckButton.Text
case "red"
lblText.ForeColor = System.Drawing.Color.Red
case "Green"
lblText.ForeColor = System.Drawing.Color.Green
case "Blue"
lblText.ForeColor = System.Drawing.Color.Green
End Select
End Sub
</script>
<html>
<head>

<body>
<form runat="server">
<!-- Insert content here -->
<IE:Toolbar AutoPostBack="true" OnButtonClick="Toolbar_ButtonClick" Runat="Server">
<IE:ToolbarButton Text="File"/>
<IE:ToolbarSeparator/>

<IE:ToolbarCheckButton Text="Blue" />
</IE:ToolbarCheckGroup>
</IE:Toolbar>
<p>
<asp:Label id="lblText" Font-Size="16pt" Runat="Server"/>
</form>
</body>
</html>
/////////////////////////////////////////////////////////////////////////////////////////
执行时出错，错误如下：

请问这是为什么呢？（注：安装IEwebcontrol完全按说明进行，而且去了变量，函数后可正常显示，还有就是在树控件中，我把《ASP.NET揭密》中的一段例子原样写入，在Sub ShowChecked(colNode As TreeNodeCollection)时，也出错，提示：TreeNodeCollection 模糊，请问这些问题到底是怎么回事）

.vb中有没有这样的语句
Protected Sysetm.Web.UI.WebControls.TextBox txtSampleText
如果没有，加上应该就可以了。

好久没打招呼了：
孟子、静芯你们会PB吗？有个问题请教：在pb中嵌套浏览器如何屏蔽调浏览器的滚动条哟？

注册了，也把DLL拷到了BIN目录里了。原因我也知道，大概意思是那样，可在程序中我有这个呀：<IE:ToolbarTextBox ID="txtSampleText"/>
那怎能么会找不到？
