Question

private void button2_Click(object sender, EventArgs e)
{
    SqlConnection con = new SqlConnection("Data Source=SYS12;Initial Catalog=Teju;Integrated Security=True");
    SqlCommand cmd = new SqlCommand("Select Picture from tblImgData where id= " + listBox1.SelectedValue + " ", con);
    con.Open();
    byte[] byteImg = (byte[])cmd.ExecuteScalar();
    string strfn = Convert.ToString(DateTime.Now.ToFileTime());
    FileStream fs = new FileStream(strfn, FileMode.CreateNew, FileAccess.Write);
    fs.Write(byteImg, 0, byteImg.Length-1);
    fs.Flush();
    fs.Close();
    pictureBox1.Image = Image.FromFile(strfn);
}

This code showing error as “Out of memory.” What might I be doing wrong, or how can I debug and solve this? Thanks!

Answer 1

Use System.Drawing.Image Class to save file then directly assign this image to your picture box.

Check this:

private void button2_Click(object sender, EventArgs e)
{

    SqlConnection con = new SqlConnection("Data Source=SYS12;Initial Catalog=Teju;Integrated Security=True");
    SqlCommand cmd = new SqlCommand("Select Picture from tblImgData where id= " + listBox1.SelectedValue + " ", con);
    con.Open();
    byte[] byteImg = (byte[])cmd.ExecuteScalar();
    string strfn = Convert.ToString(DateTime.Now.ToFileTime());
   Stream stream = new MemoryStream(byteImg);
Image img = System.Drawing.Image.FromStream(stream);

img.Save(strfn , ImageFormat.Jpeg);
    pictureBox1.Image = img;
}
