Finding Number of Records in SQL Tables

By using the following query you will be able to get all the tables with at least one record in the selected database. It will be handy when you needed to get an idea of the number of records in a database. This uses two SQL Server system views, namely SysObjects and SysIndexes.

1. SELECT sysobjects.name AS [Table Name],
2.         MAX(sysindexes.rows) AS [Number of Records],
3.         sysobjects.crdate AS [Created Date],
4.         sysobjects.refdate AS [Referenced Date]
5. FROM sysobjects
6. INNER JOIN sysindexes ON sysobjects.id = sysindexes.id
7. WHERE sysobjects.xtype = 'U' -- Filtering all the User Tables.
8.     AND sysindexes.rows > 0 -- Getting all the tables having at least one reoord.
9. GROUP BY sysobjects.name,
10.     sysobjects.crdate,
11.     sysobjects.refdate
12. ORDER BY 2 DESC -- Ordering by the number of records in table.

 

Above query will bring the following results on the Northwind database.

Resetting Windows XP Mode

Recently I had a problem using Windows XP mode simply because the password for Windows XP mode was not working.This can happen when Windows XP mode password was changed in Windows XP Mode or when the Windows XP Mode was created from another user account to the one currently logged into the physical machine.

One way to fix this is by opening Windows XP Mode Windows Virtual PC Settings and deleting saved credentials. But in my case there were no saved credentials so my button was disabled.

Second way to fix this is by uninstalling Windows XP Mode and reinstalling it.

Third way is a quicker way to do this by simply cleaning the virtual machine files in folder “C:\Users\Administrator\AppData\Local\Microsoft\Windows Virtual PC\Virtual Machines”. Make sure you are only deleting the files relevant to Windows XP Mode.

Then when you relaunch Windows XP mode, it will say that some of the required files are missing and will prompt to create a new environment. When you press “Create New” it will start the wizard to create a brand new Windows XP Mode.

If it generates any errors, you should try deleting the virtual machine file found in “<User Folder>\Virtual Machines”

After finishing the wizard you will get a new Windows XP Mode.

HTTP Error 404.13 – Not Found – The request filtering module is configured to deny a request that exceeds the request content length.

I recently got this error in one of my applications. When troubleshooting, I found my application is configured to have the default value of 30000000 Bytes for the content length, which was not sufficient for me in some of the file uploading functionalities.

Simply adding / increasing the number in the configuration file corrected this error.

Ruston’s Roses – Renmark South Australia

If you like to enjoy visiting the Australia’s largest Rose garden then you need to travel to Renmark in South Australia. The place is named Ruston’s Roses, they maintain a Rose garden of 50000 bushes in 4000 varieties. I have been there in off peak season but there were few flowers blooming so I expect it will be full of flowers in season.

To make it an interesting place for everyone Ruston’s got a small car museum as well. Till the ladies enjoy the garden gents can enjoy the cars on display. Not to mention the gift / souvenir shopping possibilities at the place. When you are tired after all that you can enjoy a light meal from the restaurant.

Samsung Galaxy S4 not Connecting to Car Audio Fix

Few months back suddenly my Toyota refused to connect to my Samsung Galaxy S4 without any reason. Earlier I could listen to music, dial calls and answer calls without issues.

But suddenly the connection between the car and the phone broke and the worst thing is I lost entire Bluetooth screen from the car audio system (Normally I have FM1, FM2, Bluetooth and AM). I thought my audio system is malfunctioning so I went to Toyota, but they said it is a known error and Galaxy S4 is having new Bluetooth version and it is not compatible with most of the car audio systems and I will not be able to use the phone with the car. This was very disappointing to me so I asked for them for the audio system update but they said no updates are available.

Then I thought to try out few things and get it fixed by myself, good news for anyone having the same issue is I solved the issue. But it is not always reliable but 95% of times it will work.

To get your S4 (or any other new device) connected into your car audio follow the steps below, they might help you.

1. First we need to get the missing Bluetooth mode (screen) back in the car audio, for this I removed all the registered devices I had in the car audio.
2. Then I registered my old Windows Mobile phone to the audio system using the settings screen (since the Bluetooth mode is not available). Any old phone like an iPhone 4G or below, Samsung Galaxy S2, Windows Mobile phones will be ok. If you get the device properly registered you will get the Bluetooth screen back when you restart the car audio system.
3. Then register your Galaxy S4 with the car audio system, and change the connection behaviour immediately. Normally the car audio will try to connect to the phone, but since the phone is having new version of Bluetooth car audio will not recognise the commands transmitted by the phone. So the system will think there is no device.

To over come the issue you need to configure the phone to make the connection. In my Toyota this is done by selecting the connection settings after the Bluetooth connection is made using the Bluetooth mode (screen). Because latest phones are intelligent they will detect that the car audio is having older version of Bluetooth and it will change the instruction set accordingly and start communicating with an instruction set which is recognised by the car audio, making everything back to normal again.

After making my phone to connect to the car, I could play my music, answer calls and dial calls without any issues.

Hope this will help you to get your car audio connected to your latest phone.

Mount Lofty Lookout

A place you would visit to enjoy great scenery while you are in Adelaide South Australia is the Mt. Lofty Summit Lookout. You will be able to see most of the Adelaide while being there. At 720 meters above sea level and 17 kilometers from the city is a good place to enjoy an evening.

To assist visitors there is an information centre to gather more information about the area and a restaurant (http://www.mtloftysummit.com) to enjoy a cup of tea. If you got some more time to spare you could also visit Cleland wild life park which is nearby.

Drive with care since the roads in the area are having bends, also be on alert since there are many cyclists active in the area. There s a big car park so you will find a space to park your car but it will cost (was $3 on May 2013) you since at all times parking fees do apply.

Kogan Smart TV Dongle Restarting

If you also bought Kogan Smart TV dongle and it keeps on restarting whenever you try to turn it on you might be able to fix it by reading on.

Mine always restarted, at a time when the Android robot man is in view or when Android word is shown.

I did two main things to get it to work normally.

A) Changed the power source – I found the Red LED light in the dongle was not having the brightness it used to have. After doing some testing I found the power adapter which came with the dongle was faulty, so I used another similar power adapter and immediately the restarting of the dongle became less.

Also sometimes this power limitation is caused by the connector slack between the power adapter and the cable. Try changing the cable or adjusting the orientation of the adapter. For example if the adapter is lying flat try to turn it to a side or try to put some kind of an object underneath to reduce the slack between the cable and power adapter.

B) Update the firmware in the dongle – In my dongle updating the firmware made the restarting issue almost vanish. So if you like to make the fix complete try updating the dongle by following the steps below.

Before starting the process make sure that you will not have any power outages until you complete your firmware update (for about 30 mins). If power is interrupted while the update is happening most likely you will have problems using your dongle again, it might even be bricked so be careful.

1. Download the new version of firmware  from the following link.
2. Find an empty USB flash drive or a Micro SD card of capacity 512MB or more.
3. Unzip the downloaded zip file into the USB flash or the SD card. Make sure only the contents of the zip file is present on SD card or flash drive.
4. Plug the SD card or the USB flash into the HDMI dongle.
5. Go to Settings, find System Update then select Local Device and select either USB flash drive or the SD card.
6. This will start the firmware update process and when completed dongle will be restarted.
7. Then you need to do the initial configuration again for things like screen size, WiFi, accounts etc.

Hope this helps you, if you have any questions let me know I might be able to help. Some of the information about updating the firmware is thanks to a reply made by Ozzie Tigar in forums.whirlpool.net.au.

Dolphin Cruises – Port Adelaide South Australia

Recently after a friend of mine told me about these cruses, we went for the cruise with few families we are friends with. In Port Adelaide 2 companies are offering Dolphin cruses. Namely they are Dolphin Explorer and Port Princess Dolphin Cruises. (For contact details please read on.)

In our cruise Dolphin Explorer took 2 and half hours to take us along the Port river. The ride is comfortable since it is not going to rough sea. On the way you will see big ships which comes into port. Unfortunately on the day we went it started raining so it was bit cold. Since the big boats are having fully covered restaurants no need to worry about the weather.

When talking about Dolphins it is bit frustrating since in our cruise we only saw few Dolphins at the start. But noting on our way, sometimes this might be because of the bad weather we had on the day. Since it costs $18 for an adult with meal I think it is value for money, so we thought to have another go later some day to check out more Dolphins. Until then I will post few photos I captured to make you interested.

There are plenty of free and paid parking in the area, so not to worry on parking. You will be able to find more information including the meal menus and other costs on their web sites.

Lock Windows

If you wanted to lock your Windows using a batch file it can be achieved using the following command.

rundll32.exe user32.dll, LockWorkStation

This will be handy if you need to lock your computer after a certain scheduled action. Simply place this in a bat file, and schedule the bat file to be run to get the computer locked.

I tried this on Windows 7.

Enabling Hibernate in Windows 8

If you have start using Microsoft’s latest Personal Computer (PC) Operating System (OS) Windows 8, by now you may have found it is different in some ways to it’s predecessors. One feature I am heavily using in Windows was again missing after installing this version of Windows, which is the hibernation feature.

So if you like hibernation shown on your power menu try doing the following.

1. Move your mouse cursor to the right side of your screen to activate the quick access menu and click on Settings and then on Control Panel.

2. Then select “System and Security”.

3. Now select Power Options.

4. From the left hand navigation menu select “Choose what the power button does” or “Choose what closing the lid does”.

5. Now on system settings screen you need to click on “Change settings that are currently unavailable” to modify the disabled options.

6. Scroll down to Shutdown settings and check the box named Hibernate and click Save Changes button.

Now if you look at the options available in your power menu Hibernate will also be part of it.

If this does not bring hibernation back, please try the following as well.

1. From the power options screen select “Change plan settings” of the active plan.

2. Then select “Change advanced power settings”.

3. Now click on “Change settings that are currently unavailable”. This will list down all the features available in the system. Scroll down and expand Sleep –> Allow hybrid sleep and turn on hibernation as you want.

 

With these changes the “Hibernate” option should start appearing in your Power options menu.
