Find it difficult to focus on work after lunch?

Do you always feel like grabbing a snooze after lunch? These simple tips will help you stay at your sharpest even after your meal.

Why do you feel tired after lunch?

There could be a variety of factors causing you to feel sleepy after lunch:

• What you eat plays an important part in deciding your energy levels. While some foods can boost your energy, others can zap it out. Junk food, sugary food or fatty food will make you feel lethargic and sleepy. These foods increase your blood sugar causing your body to release more insulin. This in turn triggers tryptophan, a kind of amino acid, known for its role in producing brain messengers or neurotransmitters related to sleep and relaxation.
• Have you been getting adequate rest? It may seem obvious but if you’ve been having stressful and sleepless nights, you’re bound to feel sleepy during the day. Try getting at least 6 -7 hours of sleep every day.
• If you have been eating healthy and are getting adequate sleep, you could be suffering from an illness. Sometimes, low fitness levels or some underlying disease could be responsible for draining you out. Your doctor should be able to detect this easily.

Tips to feel energetic after lunch

• Watch what you eat: Junk food is a strict no no. Stick to a low carbohydrate and high protein diet. In simple terms, it means potatoes, white rice and pasta are out and sprouts, beans and cabbage are in. Keep your meal portions small as large meals require more effort to digest.
• Save the alcohol for the weekend: Even if it’s an office party and you can have a glass of wine or beer, if you are expected to get back and work, it’s preferable to stay off the alcohol.
• Take a little walk after lunch: Walk off your drowsiness by taking in some fresh air. Apart from getting rid of your lethargy, it’s a good way to include some activity in your daily schedule. Especially if your job involves sitting in one place.
• Minimise your caffeine intake: I know coffee seems like a great perk-me-up, but the more coffee you consume, the more immune you get to its effects. Switch to water. Many people don’t feel thirsty in an air conditioned office and end up dehydrating their bodies.
• Make sure you have breakfast: One cannot stress enough, the importance of having breakfast. Studies show that people who have a healthy breakfast are mentally and physically more active than those who skip it.

It may be hard to believe that such simple changes in your lifestyle can magnify your energy levels drastically. Try them out !

HOW TO SURVIVE A HEART ATTACK WHEN ALONE

Let's say it's 6.15pm and you're going home (alone of course),
after an unusually hard day on the job. You're really tired, upset and frustrated. Suddenly you start experiencing severe pain in your chest that starts to drag out into your arm and up into your jaw. You are only about five miles from the hospital nearest your home. Unfortunately you don't know if you'll be able to make it that far. You have been trained in CPR, but the guy that taught the course did not tell you how to perform it on yourself..!!

NOW HOW TO SURVIVE A HEART ATTACK WHEN ALONE..

Since many people are alone when they suffer a heart attack, without help, the person whose heart is beating improperly and who begins to feel faint, has only about 10 seconds left before losing consciousness.
However, these victims can help themselves by coughing repeatedly and very vigorously.
A deep breath should be taken before each cough, and the cough must be deep and prolonged, as when producing sputum from deep inside the chest.
A breath and a cough must be repeated about every two seconds without let-up until help arrives, or until the heart is felt to be beating normally again.
Deep breaths get oxygen into the lungs and coughing movements squeeze the heart and keep the blood circulating.
The squeezing pressure on the heart also helps it regain normal rhythm. In this way, heart attack victims can get to a hospital.

How to Store or Save and Read Image in SQL Server table

How to Store or Save Image in SQL Server table

To store an image in to sql server, you need to read image file into a byte array. Once you have image data in byte array, you can easity store this image data in sql server using sql parameters. Following code explains you how to do this.

        private void cmdSave_Click(object sender, EventArgs e)
{
    try
    {
        //Read Image Bytes into a byte array
        byte[] imageData = ReadFile(txtImagePath.Text);

        //Initialize SQL Server Connection
        SqlConnection CN = new SqlConnection(txtConnectionString.Text);

        //Set insert query
        string qry = "insert into ImagesStore (OriginalPath,ImageData) _
                                    values(@OriginalPath, @ImageData)";

        //Initialize SqlCommand object for insert.
        SqlCommand SqlCom = new SqlCommand(qry, CN);

        //We are passing Original Image Path and
        //Image byte data as sql parameters.
        SqlCom.Parameters.Add(new SqlParameter("@OriginalPath",
                                    (object)txtImagePath.Text));
                                   
        SqlCom.Parameters.Add(new SqlParameter("@ImageData",
                                            (object)imageData));

        //Open connection and execute insert query.
        CN.Open();
        SqlCom.ExecuteNonQuery();
        CN.Close();

        //Close form and return to list or images.
        this.Close();
    }
   Following code explains how to read image file in to a byte array.

       
    //Open file into a filestream and
    //read data in a byte array.
    byte[] ReadFile(string sPath)
    {
        //Initialize byte array with a null value initially.
        byte[] data = null;

        //Use FileInfo object to get file size.
        FileInfo fInfo = new FileInfo(sPath);
        long numBytes = fInfo.Length;

        //Open FileStream to read file
        FileStream fStream = new FileStream(sPath, FileMode.Open,
                                                FileAccess.Read);

        //Use BinaryReader to read file stream into byte array.
        BinaryReader br = new BinaryReader(fStream);

        //When you use BinaryReader, you need to
        //supply number of bytes to read from file.
        //In this case we want to read entire file.
        //So supplying total number of bytes.
        data = br.ReadBytes((int)numBytes);
        return data;
    }

How to read image data bytes from SQL Server table

To read images from SQL Server, prepare a dataset first which will hold data from SQL Server table. Bind this dataset with a gridview control on form.

    void GetImagesFromDatabase()
    {
        try
        {
            //Initialize SQL Server connection.
            SqlConnection CN = new SqlConnection(txtConnectionString.Text);

            //Initialize SQL adapter.
            SqlDataAdapter ADAP = new SqlDataAdapter("Select * from ImagesStore", CN);

            //Initialize Dataset.
            DataSet DS = new DataSet();

            //Fill dataset with ImagesStore table.
            ADAP.Fill(DS, "ImagesStore");

            //Fill Grid with dataset.
            dataGridView1.DataSource = DS.Tables["ImagesStore"];
        }
        catch(Exception ex)
        {
            MessageBox.Show(ex.ToString());
        }
    }

   Once you have image data in grid, get image data from grid cell. Alternatively you can also get image data from Dataset table cell.

            //Store image to a local file.
            pictureBox1.Image.Save("c:\test_picture.jpg",System.Drawing.Imaging.ImageFormat.Jpeg);
           If you want you can extend this code to save image from Picture Box to a local image file.

    //Store image to a local file.    pictureBox1.Image.Save("c:\test_picture.jpg",System.Drawing.Imaging.ImageFormat.Jpeg);Points of Interest
If you see frmImageStore in design mode, I have placed picturebox1 into a panel. This panel's AutoScroll property is set to True and SizeMode property of PictureBox1 is set to True. This allows picturebox to resize itself to the size of original picture. When picturebox's size is more than Panel1's size, scrollbars becomes active for Panel.

Things you can do when Windows XP won't boot

Things you can do when Windows XP won't boot

When your computer hardware appears to power up okay, but the Windows XP operating system won't boot properly, you have to begin a troubleshooting expedition that includes getting into the operating system, determining the problem, and then fixing it. To help you get started on this expedition, here are 10 things you can do when Windows XP won't boot.

Use a Windows startup disk
One of the first things you should reach for when troubleshooting a Windows XP boot problem is a Windows startup disk.
This floppy disk can come in handy if the problem is being caused when either the startup record for the active partition or the files that the operating system uses to start Windows have become corrupted.
To create a Windows startup disk, insert a floppy disk into the drive of a similarly configured, working Windows XP system, launch My Computer, right-click the floppy disk icon, and select the Format command from the context menu.
When you see the Format dialog box, leave all the default settings as they are and click the Start button. Once the format operation is complete, close the Format dialog box to return to My Computer, double-click the drive C icon to access the root directory, and copy the following three files to the floppy disk:* Boot.ini* NTLDR* Ntdetect.com
After you create the Windows startup disk, insert it into the floppy drive on the afflicted system and press [Ctrl][Alt][Delete] to reboot the computer.
When you boot from the Windows startup disk, the computer will bypass the active partition and boot files on the hard disk and attempt to start Windows XP normally.
