How to change NTFS permissions for files or folders using Microsoft’s Extended Change Access Control List tool (xcacls.exe) tool

 

If you need a command-line tool that you can include in your batch files to change the NTFS permissions of files or folders, you can use the following tool from Microsoft.

Download iCACLS : http://support.microsoft.com/kb/919240
Article from ss64: http://ss64.com/nt/icacls.html

For example, the command below gives

icacls c:\inetpub\wwwroot\files\ /grant mary:(M,WDAC)

NOTE: xcacls is DEPRECATED.  Please use iCACLS instead which comes bundled with Microsoft Windows 2003.

The type or namespace name 'Interop' does not exist in the namespace 'Microsoft.Office' error

 

I encountered the following error "The type or namespace name 'Interop' does not exist in the namespace 'Microsoft.Office' "

Found a working solution in one of the posts in this thread.

Here’s what I did:

1. Download the Microsoft Office 2010: Primary Interop Assemblies Redistributable at this link.
2. Installed the software; it would extract as a setup file named “o2010pia.msi”
3. Navigated to the “.NET” tab and added the reference “Microsoft.Office.Interop.Word”.  You can also manually add the reference under the

   <assemblies>

   tag

   <add assembly="Microsoft.Office.Interop.Word, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71E9BCE111E9429C"/>
      

If all goes well, it should get rid of the error message just as it did for me :)

How to solve the "The type or namespace 'Packaging' does not exist in the namespace 'System.IO'" error

If you encounter this error "The type or namespace 'Packaging' does not exist in the namespace 'System.IO', here's an easy way to solve it.

Just locate the

<assemblies>

 tag in your web.config file and add this line.  It should resolve the compilation errors straightaway.

<add assembly="WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

New version of WordXML document using OpenXML SDK 2.0 with bold, color and font size formatting

I first dabbled with the OpenXML SDK 2.0 in January 2011.

At that time, there was a problem which I could not solve: specifying different font sizes, font colors and bolding effects for different words on the same line.

I managed to achieve different formatting effects for sentences on different lines, but never managed to get it working if the words were on the same line.

Today, I finally figured out how to do it, and scroll down if you are interested to look at the code.

Oh, and do remember to add in the reference for OpenXML SDK and add the imports.

Create a hyperlink using a QueryString or Form parameter in C# ASP.NET

 

This is a very short code snippet which shows you how you can create a hyperlink using a QueryString or Form parameter received from a referring page.

Note that you would need to do two things in order for this to work:

Step 1
First, paste the code below in the HTML markup.  The code below assumes that you are using a querystring parameter called “ID” that was passed over from a previous page.

<asp:HyperLink Target="_blank" ID="HyperLinkViewFeedback" runat="server"
NavigateURL='<%# String.Concat("~/Feedback/ViewFeedback.aspx?ID=",Request.QueryString["ID"]) %>'>View Feedback</asp:HyperLink>

Step 2
Add the “Page.DataBind()” method to the OnLoad of the code-behind file.

protected void Page_Load(object sender, EventArgs e)
{
   Page.DataBind();
}

After that, you should see the hyperlink with the ID automatically appended as follows:
