get-childitem c:\users\ -filter *.txt -recurse |
    select-string -list -pattern "yourtext" | foreach {$_.Path}

Finding files

• get-childitem: Get the children for a container.  In this example the container is a folder on the file system.
• The first argument is the directory to search (c:\users).
• The –filter switch is used to limit what files to search, in this example it will search files with a txt extension.
• Process all sub-directories with the –recurse switch.
• select-string: Find text in strings or files.
• The –list switch stops the search within the source once the match is found.  In other words it will not waste time looking for other occurrences of the text.
• The –pattern switch is where you specify the search text.  Regex is permitted.
• foreach:  Iterate the resulting files.
• $_.Path:  Output the full path for the file.

childitem -filter *.doc? -recurse |
    where {$_.CreationTime -gt
    [datetime]::parse("03/01/2009") -and
  $_.CreationTime -lt
    [datetime]::parse("03/31/2009") -and
        $_.length -gt 50}

The first line recursively finds all files with a doc or docx extension.

childitem -filter *.doc? -recurse | 

Lines 2-3 look for a file with a creation time greater than (-gt) March 1st 2009.

where {$_.CreationTime -gt
[datetime]::parse("03/01/2009") -and 

Lines 4-5 look for a file with a creation time less than (-lt)  March 31st 2009.

$_.CreationTime -lt
  [datetime]::parse("03/31/2009") -and 

And the final line looks for files larger that 50 bytes.

$_.length -gt 50}

This site has been running for over five years on the .Text blogging platform.  .Text was abandoned years ago and has suffered from lack of attention.  I’ve delayed moving to new software because I knew it would take a lot of time to get it done correctly.  This month we moved all of our websites to a new server so it was time, Anyway the move is done and the site is now happily running on WordPress.

I have tried to anticipate any changes to post URLs and have URL rewriting enabled. 

I started a new blog at wpfwonderland.wordpress.com that’s dedicated to WPF topics.  I’ll have a companion website up and running sometime this month too.(www.wpfwonderland.com )

Please check it out.  I’m really excited about WPF.  Can’t wait to talk to you about all the cool bits.

If you are an ASP.NET developer you’ll be happy that the Web Deployment and Web Application projects are now included.

Microsoft has added some interesting new features in the SP too.

• Multicore support for profiling
• Multicore support for code gen
• Team Server performance improvements
• See the Microsoft website for more details

There are several version of the SP. Pick the one that matches your version of Visual Studio.

• Visual Studio 2005 Team Suite SP1 (includes SP1 updates for Standard, Professional, and Team Editions of Visual Studio 2005)
• Visual Studio 2005 Team Foundation Server SP1
• Visual Studio 2005 Express Editions SP1
• Visual Studio 2005 SP1 Update for Windows Vista Beta

Seriously, if you are using Visual Studio 2005 you should install this SP as soon as possible.

Wait, there’s more.  A free copy of Office 2007 Pro ($500) if you watch some marketing videos for Office.  So far I haven’t seen the catch, unless it’s a fake site.

I don’t understand the reasoning behind the offer or the odd marketing videos on YouTube.com but do you care?  Nah, it free.  If you haven’t tried Vista you really should.  This just makes it easier.

Today I finally solved one of the annoying dilemmas that crops up when using the Treeview.

The problem

A treenode can be selected or expanded.  Selecting the node causes the SelectedNodeChange event to fire if the Treeview is configured correctly.  Clicking the + icon on a node causes the TreeNodeExpanded event to fire.  The selected event will not fire if the node is in Navigation mode.    This behavior makes sense most of the time.  The node is acting  as a navigation link  - it causes the browser to take you to a new page which means there is no postback.  Your are going to a new page, without returning to the server first.

If the node has its NavigationUrl property set to an empty string, the node is in Selection mode.  If the NavigationUrl is a non-zero length string ,the node is in Navigation mode.

For our project I wanted the children nodes to expand whenever the user selects a parent node.  Yes, the user can click the + symbol to expand it,  but our testing showed that many users expect the node to expand by clicking the node text instead. Since the nodes are in Navigation mode I couldn’t  put the code in the SelectedNodeChanged event.

My solution?  Use the TreeNodeDatabound event to examine each node as it is being bound to the tree.  If the current page URL matches the treenode NavigationUrl I expand all the of the current nodes children.  It solves my problem.  It still doesn’t cause the SelectedNodeChanged to fire so it may not solve all your troubles. At least it’s a start.

Protected Sub treeMainMenu_TreeNodeDataBound _
           (ByVal sender As Object, _ 
ByVal e As System.Web.UI.WebControls.TreeNodeEventArgs) _
Handles treeMainMenu.TreeNodeDataBound
‘ other binding code here…
If Request.Url.PathAndQuery = e.Node.NavigateUrl Then
e.Node.ExpandAll()
End If
End Sub

Your code helped me indirectly. Thanks a lot.

Thanks you code also helped me indirectly.
Saved quite some time.

Selection vs Navigation 7/19/2006 10:07 AM Alejandro Cifuentes

Thank you very much for your tips. I have made a change to your code. I need that a navigation node shows as an hyperlink, to expand the lower ones, so i modified the code to:
If e.Node.NavigateUrl = "" Then
e.Node.SelectAction = TreeNodeSelectAction.Expand
End If
Best regards,
Alejandro.

I used you code (thanks alot) and got this working in a demo project, but the more I played around with firing different events ans setting databindings … eventually it stopped working. No I cannot get it to work again. The TreeNodeDataBound event fires, and the call to expandAll() runs, but it does not expand. There seems to be a bunch of different properties in this control that force other properties to change to thier default, irrespective of what you set.
For example setting populateondemand in the databindings
like
<DataBindings>
<asp:TreeNodeBinding PopulateOnDemand=true
TextField="Title" NavigateUrlField="URL" />
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnaspp/html/CustSiteMap.asp)
or setting it in code in the TreeNodeDataBound event does not work.. must be overriden by another setting.
Anyone else experience this.

Here is my code which no longer works. Where the TreeNodeDataBound event fires, and the call to expandAll() runs, but it does not expand.
<asp:TreeView ID="TreeView1" runat="server" DataSourceID="SiteMapDataSource1" ExpandDepth="1"
OnTreeNodeDataBound="TreeView1_TreeNodeDataBound">
</asp:TreeView>
protected void TreeView1_TreeNodeDataBound(object sender, System.Web.UI.WebControls.TreeNodeEventArgs e) {
if (Request.Url.PathAndQuery == e.Node.NavigateUrl) e.Node.ExpandAll();
}

8/17/2006 11:39 AM Andy

ok I remember I need PopulateNodesFromClient="false" in order to get the click on the text to navigate and expand.
<asp:TreeView ID="TreeView1" runat="server" DataSourceID="SiteMapDataSource1" ExpandDepth="1"
OnTreeNodeDataBound="TreeView1_TreeNodeDataBound" PopulateNodesFromClient="false">
</asp:TreeView>

Thank You!! I have been searching for 2 days and have found tons of code but nothing that did exactly what I needed it to. This was just what I was looking for. Thanks a ton…
