Enabling Remote Connections on SQL Server 2005

If you do the default installation of SQL Server 2005 the remote connections wont be enabled. The result of this will be that no one else wont be able to access to the SQL server instance of your machine resulting your databases to be used only from your machine. All the connections from outside to the databases hosted in your SQL server instance will be denied.

To make your databases accessible you have to do the following.

Step 1 - Right click on your SQL server instance in the Server Management Studio and click properties and get to the server properties.

In the left pane select Connections.

Check whether Allow remote connections to this server check box is selected under Remote Server Connections (this is defaultly selected).

Step 2 - Open SQL Server Surface Area Configuration Tool.

Click Start -> Programs -> Microsoft SQL Server 2005 -> Configuration Tools -> SQL Server Surface Area Configuration.

or

Browse to your Program Files directory and go to the path Microsoft SQL Server\90\Shared (For example C:\Program Files\Microsoft SQL Server\90\Shared).

There you need to find the executable named SqlSAC.exe and double click on it.

It will open SQL Server 2005 Surface Area Configuration screen.


Step 3 - Click on the Surface Area Configuration for Services and Connections link to open the configuration screen.

Select the Local and remote connections radio button.

Then choose accordingly the next radio button. For example if you need to make your server accessible through both TCP/IP and named pipes select the last radio button or else just select TCP/IP only if you only needs TCP/IP as illustrated in the image.

Then press Ok to save the changes.

Step 4 - We need to restart the SQL Server to apply the changed settings.

  • If you have installed SQL Server 2000 in your machine, double click on the SQL Server icon on the system tray area.
Select the SQL Server 2005 Server and click the Stop button to stop the database server and once it is successfully stoped press on the Start/Continue button to restart the database server.


  • If you have only installed SQL Server 2005 in your machine open SQL Server Configuration Manager by going to Start->All Programs->Microsoft SQL Server 2005->Configaration Tool->Configuration Manager.

Then select SQL Server 2005 Services from the left pane and select SQL Server from the right pane, right click on it and click Stop. Once it is successfully stoped press on the Start button to restart the database server.


When the SQL Server database engine restarts successfully you will be allowed to connect to the databases on your server from remote locations.

Results not sorted Correctly when System.Data.DataTable.Select(Filter, Sort) is used

If you are using Windows 2003 SP1 there is an issue in System.Data.dll in .NET Framework 1.1 SP1 which will cause the resulted data to be incorrectly sorted. This is a bug of .Net Framework 1.1.


DataSet1.Table1.Select("Filter1=1 AND Filter2=2 AND Filter3=3", "SortColumn1")

The result of the above statement wont be sorted according to the SortColumn1. But it will be sorted using the Column 1 of the dataset. But if you remove the AND operators used then the result will start to sorting again.
If you really want to sort the things while using AND operators, try making the required sorting column (SortColumn1) the first column in the datatable.

At the moment there is no download and install solution from Microsoft but they said to contact them to find out a solution.

If you like to know more on this you can visit the related Microsoft support center from the following link.

Disabling the Shutdown Event Tracker in Windows 2003

If you try to Shutdown or Restart a computer running Windows 2003 OS you always have to give a reason for the shutdown or restart. This is because Shutdown Even Tracker is enabled. This will be great if it is a server, but this may be annoying if this is a normal PC. If anyone likes to stop this below I am discussing how to accomplish it.

1. In the Run Window (Start -> Run) type GPEdit.MSC and press enter.
2. Expand the Computer Configuration then Administrative Templates and then select System.
3. Double click on Display Shutdown Event Tracker to get the properties of it and select Disabled and click ok.

After these steps you will be able to shutdown the system as normal.

Sometimes your group policy settings may not apply immediately due to various reasons. To force apply the settings open the command window (Type Cmd in the run window) and type GPUpdate /force
This will force the changes made and any errors will be logged to the system event log.
If the shutdown event tracker keeps on appearing then probably an error may have occurred while trying to apply group policy settings. Go to Event Viewer and check for errors.

Note - If you are in a domain then you needs domain rights to disable shutdown event tracker.

Registering Crystal Reports

Are you getting an exception
"Internal Exception: Cannot find KeycodeV2.dll or invalid keycode."
when you try to open a report done by Crystal reports?

Errors relating to KeycodeV2.dll can occur in VS.Net because of one of the following issues.
1. KeycodeV2.dll file is not accessible,
2. Does not have access to the registry keys which relate to KeycodeV2.dll,
3. Does not recognize the product Keycode stored in the registry.

Here I will address the last one, because most of the people doesn't know how to correctly register Crystal.

  • As the first step you have to add the licensing merge module which is Crystal_regwiz2003.msm (if you are using VS.Net 2002 the file will be RegWiz.msm) to your setup project.
  • Then get to the properties window of the Merge Module.
  • Expand the Merge Module Properties section in the Properties window and you will see a property called License Key.
  • Enter the License key of your Crystal reports there.

If any one is wondering what the License key is, read on,

To get a license key you have to register Crystal with Business Objects. After registering you will get an email containing a registration number and unique key code (If your copy is already registered you can get to the Product Code by going to menu Help -> About Microsoft Development Environment, in Visual Studio .NET. If it is registered the Product Code is the code besides Crystal Reports for Visual Studio .NET.) Copy the Product Code (Product Code consists of 19 characters and looks something like xxxxx-xxxxxxx-xxxxxxx.) into the License Key property of the above merge module.

Next time you build and install the project the error will vanish.

If you still get the error or if you are interested in reading more into this following URL might be useful to you.

Getting a Crystal Report Parameter value in VB.NET

After setting a parameter value of a crystal report there is no easy way of getting the value. So I found this to get the parameter value.


CType(CType (CType (CType (CType (CType (rpt.Parameter_paraArea, CrystalDecisions.Shared.IParameterField), CrystalDecisions.CrystalReports.Engine.ParameterFieldDefinition).CurrentValues, CrystalDecisions.Shared.ParameterValues).Item(0), CrystalDecisions.Shared.ParameterValue), CrystalDecisions.Shared.ParameterDiscreteValue).Value, Object)

rpt is the Crystal Report, paraArea is my parameter name which I needed to get the value of.

Hope this helps.

Playing Media Files in .Net Compact Framework 2.0

I have seen many people asking how to play media files in device applications. Here I am playing media files using Windows Media Player.



This is the ProcessHandler class which imports Coredll Dll and uses it's CreateProcess to create a seperate process with the required application.


This is the main form which has a button to start the Player, then it will ask the user to browse for a media file to play.


The ProcessHandler.CreateProcess function can be used to start any application which is installed in the device by simply replacing the 'WMPlayer' by the required application qualified name (IExplorer).

Interop Forms Toolkit 1.0

Are you in Visual Basic 6 (VB 6) and would like to join the .net 2.0 fun? But is your application size stopping you?

Now with the Interop Forms Toolkit 1.0 you can run forms that you have created with .net hand in hand with vb 6 forms in a VB 6 process.
Big Picture? You don't have to convert your entire application to .net but you can partially convert your application to .net or the new forms that you plan to create can be done in .net and used in your VB6 application.

When trying to Run or Build a .Net Compact Framework project, Visual Studio 2005 (VS2005) giving an error MSB4018 ?
--------------------------------------------------------------------------------------------

This a curious error which VS2005 gives before refusing to build the project in anyway.
The work around for this is to close the VS, restart VS and Rebuilding the project.
