Here are a few ways

Very Basic method of adding new node

<br />
                 private void BuildMenu()<br />
        {<br />
            <br />
            tview.Nodes.Add("Item1");<br />
            tview.Nodes.Add("Item2");<br />
            tview.Nodes.Add("Item3");<br />
            tview.Nodes.Add("Item4");<br />
        <br />
        }<br />

Slighty more complex

<br />
          private void BuildMenuNodes()<br />
        {<br />
            AddNewNode("Item1", tview);<br />
            AddNewNode("Item2", tview);<br />
            AddNewNode("Item3", tview);<br />
            AddNewNode("Item3", tview);<br />
<br />
        }<br />

Even More Complex way

<br />
       <br />
        // Add Nested Nodes<br />
        private void AddNestedNodes()<br />
        {<br />
            TreeNode node;<br />
<br />
            node = tviewExplorer.Nodes.Add("Security");<br />
            node.Nodes.Add("Item1");<br />
            node.Nodes.Add("Item2");<br />
            node.Nodes.Add("Item3");<br />
<br />
            node = tviewExplorer.Nodes.Add("Item1");<br />
            node.Nodes.Add("Item A");<br />
            node.Nodes.Add("Item B");<br />
            node.Nodes.Add("Item C");<br />
                   <br />
        }<br />

// This is the MS prefered method due to the performance gains

<br />
<br />
              private void AddNodesRange()<br />
        {<br />
            TreeNode[] nodes = new TreeNode[3];<br />
<br />
            nodes[0] = new TreeNode(""ItemA");<br />
           <br />
            nodes[0].Nodes.Add("Item2");<br />
            nodes[0].Nodes.Add("Item3");<br />
            nodes[0].Nodes.Add("Item4");<br />
<br />
            nodes[0] = new TreeNode(""ItemB");<br />
           <br />
            nodes[0].Nodes.Add("Item5");<br />
            nodes[0].Nodes.Add("Item6");<br />
            nodes[0].Nodes.Add("Item7");<br />
<br />
            nodes[0] = new TreeNode(""ItemC");<br />
           <br />
            nodes[0].Nodes.Add("Item21");<br />
            nodes[0].Nodes.Add("Item31");<br />
            nodes[0].Nodes.Add("Item41");<br />
<br />
<br />
          tviewExplorer.Nodes.AddRange(nodes);<br />
<br />
<br />
        }<br />

If the application has been properly architected it should just be a matter of rewriting the presentation (UI) layer - perhaps with the odd addition elsewhere to support a stateless model of working. If it hasn't been well architected then you are looking at rewriting the whole application.

Salvaging source code with Reflector, recompiling code with changes.

Hello, I posted an earlier question about missing codebehind files, which I have since had answered.

I have an Aspnet 1.x website with .aspx and .dll files on the server; the codebehind files are not on the server, and the previous developer has neglected to leave any source code behind.

I have used Lutz Roeder's Reflector program to decompile the .dll, and now I can see all the juicy codebehind for each of the pages of the website.

My question now is this:

I want to make some minor changes to validation code. Can I take all the VB code reconstructed by Reflector, pour it into a new Codebehind page with the changes I want to make, and recompile just that page?

This seems pretty straitforward, but I want to be sure I am not about to find a pitfall. Will I need to reconstruct all the VB codebehind pages for the whole site for it to recompile, or is one page ok?

Thanks!

if u are having .aspx file same name as codebehind files as u are having from .dll then u can do it in this way. open application then click on .aspx page to view codebehind if it's coming blank then just copy paste all code for .vb file in this file. and then just compile it. done.

u can do it with one page only also.

Thanks,
Sun Rays

Thanks very much for your reply!

Yes that sounds pretty much what I need to do -- the app works, so the old code behind has all been compiled into .dll and works. I just wanted to be sure that if I reconstruct just one codebehind file as you say, and recompile, the app won't need all the other 30 codebehinds reconstructed as well.

Thanks again!

com component on aspx page

i have created a simple activex control.
it loads successfuly on the aspx page. it displays its user interface as created. ( one text box and a command button )

following is the vb6 code for the activex control

Option Explicit
Dim displaytext_value As String

Private Sub Command1_Click()
Text1.Text = displaytext_value
End Sub

Public Property Get displaytext() As String
displaytext = displaytext_value
End Property

Public Property Let displaytext(ByVal vNewValue As String)
displaytext_value = vNewValue
End Property

Private Sub UserControl_ReadProperties(PropBag As PropertyBag)
displaytext_value = PropBag.ReadProperty("displaytext", "")
End Sub

Private Sub UserControl_WriteProperties(PropBag As PropertyBag)

PropBag.WriteProperty "displaytext", displaytext_value, ""

End Sub

-----------------------------------------
following is the aspx page code

<object style="Z-INDEX: 110; LEFT: 304px; WIDTH: 176px; POSITION: absolute; TOP: 296px; HEIGHT: 176px"
="" codebase="TestCtl.ocx" classid="clsid:4C86F415-A10F-4785-B7D0-549A37D20F08" viewastext="">
<param name="_ExtentX" value="4657" />
<param name="_ExtentY" value="4657" />
<param name="displaytext" value="this is a test control" />

-------------Now the Problem ----------------------------

this control is loaded in the page when its opened in the web browser.

But on click of the command button , value of displaytext property i.e.
"this is a test control" should be displayed in the textbox.
and that is Not Happening.

if i use this control in vb.net windows application. it works and value is displayed

Any Suggestions.

Thanks

Hi guys,

I am very glad to be here. I have a doubt.I have used
window.close(); in javacsript to close a web page. It works fine but it asks for a confirmation/ it displays a message box. But i don't want this message box to be poped up. Is there any way to exclude this message box?
Or can we close a webpage in any other way?

waiting for your valid reply...
thanks in advance

This is being asked for security reasons. You can avoid this by workarounds.
Before calling close(), get the window in a variable and close. HTH.

Assign some value to window.opener. That way IE would get to think that the window is created by you and it would obey the master without any demur.

If you are accessing this zip file from your application, check that application (ASP.NET, IIS in case of Web application) as enough rights to access it

xslt.Transform

<br />
strXmlNames = "<?xml version=""1.0"" ?><users>" & strXmlNames & "</users>"<br />
        Dim xDoc As New XmlDocument<br />
        Dim xPathNav As XPathNavigator<br />
        Dim xslt As XslTransform<br />
        xDoc.LoadXml(strXmlNames)<br />
        xPathNav = xDoc.CreateNavigator<br />

        xslt.Load(Server.MapPath("Names.xsl"))<br />
<br />
        xslt.Transform(xPathNav, Nothing, Response.OutputStream)<br />

The above code works well on .NET 2005 but when I write the same on 2003 it shows the following error with blue underline on the last line

xslt.Transform(xPathNav, Nothing, Response.OutputStream)

Error:Public Sub Transform(System.Xml.XPath.XPathNavigator, args as System.Xml.Xsl.XsltArgumentList, output as System.IO.Stream) is obsolete. You should pass XmlResolver to Transform() method.

Can anybody suggest how this line should be changed for 2003?
Thankyou.

What is .NET 2005? Do you mean Visual Studio? I think you have different settings for VS2003 and VS2005.

If I am not mistaken this is only warning. You have set "treat warnings as errors" in project properties. Now how to fix it: well, if you work with .NET framework 2.0, don't use XslTransform, use XslCompiledTransform. If you don't, use XslTransform.Transform Method (XPathNavigator, XsltArgumentList, Stream, XmlResolver) [^] overload of Transform().
