Further more if you are seeking ways to change application permissions using code, following link will help you to get more details of the Application Permissions class from RIM device API.
Do you know that you can programmatically stop the user changing the date and time of a Pocket PC device?
This is useful if your applications need to take time accurately for some reason from the device.
The following code will disable the user from accessing the date time changing settings using his Windows Mobile powered device.
If you want to re-enable the setting, to make the user able to change the data and time use the below code.
To disable right click context menu you can use one of the following methods.
Method 1 – Using attribute oncontextmenu attribute of the body tag.
By using this you can block the right click action and the context menu without using JavaScript.
This will be useless if you need to do some action on the click. In such a case use the Method 2.
Method 2 – Using JavaScript.
Place the following JavaScript and modify the script as you need. This will just show a popup window to the user saying that Right clicking is disabled.
Here is a small code that I wrote to find the image format of an image.
This code will check for the raw image format of the image you select and will display in a pop up window.
Hope this helps.
If you tried to open a port in Windows Firewall which comes with Windows Server 2008 R2 you will find that Microsoft had given Windows Firewall a new look and feel.
At first you may feel that you are lost with the new interface, so thought to show how to open a port.
I will be creating an inbound rule opening the port 1443, which normally SQL Server is using for communications (Yes this machine is having SQL Server installed).
Go to Start -> Control Panel -> Windows Firewall.
This will bring the New Inbound Rule Wizard.
Select Port since we are going to open a port, if you need to open an application you can select the Program radio button, to create a rule based on an existing rule use Predefined radio button, use Custom to create a custom rule. Press Next to proceed.
Make sure TCP is selected and type in 1433 in the Specific local ports textbox then press Next.
Give a name for the rule and click Finish.
At the beginning when you try to install Microsoft Office SharePoint Server (MOSS) 2007 on Windows Server 2008 R2 it will hesitate a little. So I thought to put the steps in.
Step 1 - Download the correct Setup.
You will not be able to use your normal SharePoint Setup to install MOSS on Windows 2008 R2, if you try you will see the following message appearing continuously.
Download the required version from the following Microsoft URLs.
Windows SharePoint Services 3.0 with SP2 (x86)
http://www.microsoft.com/downloads/details.aspx?FamilyId=EF93E453-75F1-45DF-8C6F-4565E8549C2A&displaylang=en
Windows SharePoint Services 3.0 with SP2 (x64)
http://www.microsoft.com/downloads/details.aspx?familyid=9FB41E51-CB03-4B47-B89A-396786492CBA&displaylang=en
Step 2 – Install MOSS using the setup.
Installation will not have any hiccups if you downloaded the correct version.
Step 3 – Configure MOSS.
When trying to configure MOSS and if your SQL Server is running in another machine which has Windows Server 2008 R2 then you will sometimes get an error saying the SQL Server is not present.
Mainly the reason for this would be that, in your SQL Server machine the Windows Firewall is turned on. Easiest step is to turn it off, but if you are worried about your security then read the other article I have on enabling a port in Windows Server 2008 R2.
After correcting the SQL related issue then you will be able to complete the MOSS configuration wizard successfully.
If you get into any more issues contact me, I will try to help you out as I can.
d. Select the site or the farm to backup the entire SharePoint farm. 
2.) Using the STSADM tool.
Even though Microsoft had provided a UI method to backup a SharePoint site the best way to get it done is by the STSADM tool. If you are unfamiliar with STSADM refer the following post http://arjunachith.blogspot.com/2009/11/stsadm.html.
You will be able to use the following command to get a backup of a site using STSADM.
STSADM.EXE -o backup -url http://MySharePoint:10000/ -filename E:\Folder_Name\SiteBackup.bkp -overwrite
o - Mentions that the backup is an operation.
url - URL for the site collection that you need to backup.
filename - Path to the backup file, even a network path such as \\Machine_Name\Folder_Name\File_Name.ext can be provided.
overwrite - Will overwrite an existing back file if found in the backup location.
Instead of giving the path in the filename you can use the directory parameter to mention the location as well it is shown below.
STSADM.EXE -o backup -url http://MySharePoint:10000/ -directory E:\Folder_Name -filename SiteBackup.bkp -overwrite
directory - Location for the backup, even a network path such as \\Machine_Name\Folder_Name can be provided.
filename -The name of the backup file.
The status will be shown in the command prompt.
If you would like to know the full set of available parameters for the backup operation visit the Microsoft at http://technet.microsoft.com/en-us/library/cc263441.aspx.
To learn more visit the following TechNet link.

Recently I had to install and configure WSUS (Windows Server Update Services) on our company. 
You will now see a set of cod files with names like App-1.cod, App-2.cod, App-3.cod, etc.
Step 2 - Prepare the ServerAPN or Access Point Name is a setting which needs to be set on the mobile when we need to get connected to internet using the phone.
APN changes from one mobile service provider to the other. For example Dialog will have http://www.dialogsl.com/ Rogers will have internet.com set as their APN.
But letting users set the APN manually is always not the preferred way. Recently we developed an application for BlackBerry which the user needed to get to the internet without he manually setting the APN. The application was supposed to be delivered through BlackBerry App World so manually setting APN was not an option. In a case like this what you have to do is set the APN programmatically into the connection.
String URL = “www.SomeServer.com”;
StringBuffer bfURL;
bfURL = new StringBuffer ();
bfURL.append (URL);
bfURL.append (";deviceside=true ;apn=internet.com");
bfURL.append (";tunnelauthusername=UserName;tunnelauthpassword=Password");
String FinalURL = bfURL.toString ();
In the above code I have set the Rogers APN in to this connection.
If you need more details on the parameters used or need to know about the other parameters you are eligible to use such as WapGatewayIP, WapGatewayPort, WapGatewayAPN, etc visit the following link to view full details of the connector class.

Recently I managed a project which targeted iPhone and SharePoint server. This was a project for Dimo who are the dealers for Mercedes Benz in Sri Lanka. Total software services were provided by IronOne Technologies.
When we finalized the technologies I thought that this project will be an interesting one.
But the real interesting part was on the day when I saw all the Benz models present on the day. Even though I have seen international car shows before this, this is the first time I have seen this much of cars of the same manufacturer on the same place live.
You will agree after you see the photos.
