The POP3 service could not create the mailbox – the account already exists

In Windows Server 2003, I have configured POP 3 service, created domains and mailboxes.
I have created many users and associate mail boxes in the POP3 service and deleted for some reasons.
When I try to create the same user I have got the error:
The POP3 service could not create the mailbox - The account already exists

Even on manually deleting the folders (mailboxes created for each user created), I got this error.
Reason:
Then I came to know that the user associated with the mailbox is not deleted.
Right Click on My Computer -> Manage -> Administrative Tools -> Computer Management -> System Tools -> Local Users and groups -> Users -> Delete the user account for which you are unable to create the mailbox.
Note: Check the user associated with any other applications or any services before deleting the user.
Now, try creating the mailbox, you will be able to create the mailbox successfully!

Download Image from Right Click Disabled Website

In this article, we will know a small trick where we can download the images from the web page in which the right click is disabled in the web page.
Usually, web masters will disable the right click on the web pages in order to protect the content in the web page.
But sometimes, we need to download the images or copy the content from the web pages. Following are the different steps:
1. In the web page, only Right Click is disabled. Hence, we will use LEFT CLICK. Point the image and left click on the image and then drag the image to the desktop or to the address bar in the browser. Hurray! You can save the image.
2. In Internet Explorer, we can disable the active scripting and copy the image. The reason behind this is kind of scripting is written using “JAVA SCRIPTS”.Got to IE -> Tools -> Internet Options -> Security Tab -> Custom level -> Go to Scripting -> Active Scripting -> Disable -> Click OK and restart the browser

3. In Mozilla Firefox  the steps is as follows:
Open the browser -> Go to Tools -> Options -> In the Content Tab -> Uncheck or Deselect the Enable JavaScript -> Restart the browser

There are many third party tools which enable to download the images and contents. But the above are the few easy steps to achieve the goal!

Reading the Custom Properties of MS Office Word 2007 & 2010 documents

Earlier, we have discussed about reading the Summary and Custom Properties of Word 2003 using DSO DLL.

Here are the articles references

Basics of DSO DLL

Reading Summary Properties of Word 2003

Reading Custom Properties of Word 2003

As already mentioned in the above articles, DSO dll is a 32 bit and also it has OLE property reader class, which can read only the office 2003 documents.

The same DSO file cannot be used for reading the properties of 2007 & 2010. This is because, word 2003 stores the properties in OLE type and hence DSO has capabilities to read the properties. But word 2007 and 2010 stores in XML formats.

Want to know how the office 2007 & 2010 stores the properties in XML formats?

Change the extension of word 2007 or 2010 documents from .docx to .zip. Now extract the contents.

You will see many xml files inside that folder.

Now open the folder -> docProps folder -> 3 files will be there                     
 1.  App.xml – it stores the document’s summary properties

     2.   Core.xml – it stores the document’s summary properties

     3.   Custom.xml – it stores the document’s custom properties

The below snap shot shows the custom.xml file of a word 2007 document

It is possible to read the custom properties of word document using Office DLLs (which is deployed when you install a MS office in a machine).

But how to read the properties without using Office DLLs?

Hence, we will go for an open source dll provided by Microsoft called Open Office XML SDK 2.0.

The same can be downloaded from the below link

http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=5124

It has the capabilities to read the xml properties from the MS office documents.

Code snippet for reading custom the properties of word 2007 & 2010

public Dictionary<string, string> WDGetCustomProperties(string filename)
{
using (var package = WordprocessingDocument.Open(filename, false))
{
var properties = new Dictionary<string, string>();
var customProps = package.CustomFilePropertiesPart;
foreach (var property in package.CustomFilePropertiesPart.Properties.Elements<CustomDocumentProperty>())
{
                    if (property.Name == "Name")
                        Name = Convert.ToString(property.InnerText);
                    if (property.Name == "Expertise")
                        ExpertiseIn = Convert.ToString(property.InnerText);
                    if (property.Name == "Place")
                        Place = Convert.ToString(property.InnerText);
}
 return properties;
}
}

Note: Don’t forget to declare the 3 variables used for storing the values in theabove code.

Hence, this article shows you how to read the custom properties of the word 

2007 & 2010 documents.

To know how to create the custom properties in the Word 2007 & 2010 read

Creating Custom properties in Word 2003

In the articles Part I,Part II and Part III we have discussed about how to read the custom properties of word 2003 using  DSO dll in C# .Net.
In this article we are going to see about creating a bookmark and set the custom properties for the Microsoft Word 2003.
Steps
1. Open the Microsoft Word 2007 and create a new word document.
2. For creating the Bookmark, we need Forms option in the Microsoft Word Menu.
3.  Right click on the Menu bar and you will see forms options and check the option you will see the forms menu

4.   Then click the Textbox option (will be having a symbol ”ab”)

5.  Insert a text box and mouse click to see the properties.

6.   Now in the Bookmark option give the property name (here I gave it as CompanyName )

7. Now go to File Menu->properties-> Custom properties tab as shown below

8.  Now in the Name field give the Name (I gave as TestCompany) and check the Link to Content so that you will see the bookmark created and link the content we have created (CompanyName)

9. Now you will see the added property as below.

10. Click Add and now the properties are set. If you type a value in the document, the value must be assigned and you can see in the properties as shown below.

So, once the properties are set we can read the values using c# .Net.

Enjoy!

Reading Document Properties

Part I

We are going to discuss about a interesting topic which can be used in SharePoint and also in .Net.

It is possible to reading the summary properties and custom properties of the word document and it is also one of the requirements now a days.

This can be done through using DSO dll which can be downloaded from the below link

DSO Setup Download Link

(Important Note: This is a 32 bit dll )

What is DSO dll ?

The Dsofile.dll sample file is an in-process ActiveX component for programmers that use Microsoft Visual Basic .NET or the Microsoft .NET Framework. You can use this in your custom applications to read and to edit the OLE document properties that are associated with Microsoft Office files, such as the following: 

• Microsoft Excel workbooks

• Microsoft PowerPoint presentations

• Microsoft Word documents

• Microsoft Project projects

• Microsoft Visio drawings

• Other files that are saved in the OLE Structured Storage format

The Dsofile.dll sample file is written in Microsoft Visual C++. The Dsofile.dll sample file demonstrates how to use the OLE32 IPropertyStorage interface to access the extended properties of OLE structured storage files.

Features of this DLL

1. This dll is 32 bit and can read only Microsoft word 2003 (ie., .doc) formats only.

2. It has a OLE property reader class which can read the properties of the word document.

3. Using this dll, we can read both the Summary properties and also the Custom properties we create for the documents.

4. Also with this dll, we can set the custom properties programmatically.

Also, Read how to extract the summary properties of the word document in this article Part II.

Recommendations for maintaining Infopath performance

I'm creating an InfoPath form that is a bit large and starting to lag so I decided to look up better practices for developing InfoPath forms to maintain performance. Here is what I found online:

- Keep views from being too large or complex. Split large views into several smaller ones with buttons to switch between them.

- Avoid lots of tables (data or layout) in any single view.

- Use Master/Detail to reduce the number of controls in one page, whenever possible.

- Try to use filter to filter the table rows (instead of conditional

formatting).

- Avoid large repeating data structures that can grow to many pages.

-Avoid complex nesting of optional and repeatable sections. These are quite complicated to layout and also can quickly cause a single view to become very large.

- Avoid using Percentage width for your controls if your view contains lots of nested controls. We have seen over 50% improvements by using Fixed Width. You can apply specify a fixed width in the control's properties dialog.

- Be aware of exactly what your business logic does. For example, onAfterChange can fire multiple times for a single edit.

- Rather than querying for all the data then having InfoPath just show a small amount, refine your query and only bring the data you plan on displaying into InfoPath.

- Only get the data you need to load the form. Don't pre-populate data sources that aren't necessary on load.

- Merge static xml data sources into one if you have multiple xml data connections.

- Use Expression Box to display calculated value if you don't need to store the value. If you have business logic to trigger all the calculation, only trigger necessary calculation. Triggering large amount of calculations is costly.

- When using digital signatures, only digitally sign the information you need to. Signing takes a screenshot of the data signed and encodes it in the form. The larger the screenshot, the larger the xml will become with the encoded image.

- Avoid attaching large files to the form. These files are encoded in the xml and can cause issues if they become too large. Provide links over embedding large files if possible.

- Avoid embedding images in a form. For the same reasons as above.

What is 12 and 60 Hive in SharePoint ?

You'll hear SharePoint people talk about and refer to the "12 Hive" or the "60 Hive" regularly. We don't know what it is and we use it .

The "Hive" concept was coined by Todd Bleeker. So what does it mean?

12 Hive is the location where MOSS 2007 and WSS 3.0 install their files on the file system. 
The same thing applies to 60 Hive which, as you may guess is the location of SPS 2003 and WSS 2.0 files. 

Locations:

12 Hive C:\Program Files\Common Files\Microsoft Shared\web server extensions\12
60 Hive C:\Program Files\Common Files\Microsoft Shared\web server extensions\60
