City State Country From public IP Address ASP.NET

To get City, State, Country, details From public IP Address first we need to get PublicIp as mentioned this article

clients public ip address in (C#)

Next to get the details free registration for your website is required to get API key.

If you don’t have an API key yet, just go to here and register for your free API key. You will need this API key to be able to use our newer APIs.

clients public ip address in (C#)

Generally web developers need clients public ip address to store the ip in the DataBase when loging the client for some perticular security reasons. So here is the simple way to get Clients public IP address...

        WebClient webClient = new WebClient();
        string ipAddress = webClient.DownloadString("");

For the WebClient we need the namespace as using System.Net;

I hope this is the simple way to get the IP.

save / retrieve image in SQL SERVER database (C#)

I think storing images in Database can save a developer lots of time and can ease his life while dealing with visuals, either creating a local application or a web application. Think of storing your images of a certain web application in a database instead in a directory exits somewhere in a cloud which one-a bit headache and second-completely transparent with respects to its location. So, here we are, I am going to create here a local application through which we can insert and retrieve an image using c# from a sql server 2008 database.

 First of all you need to create database to store and retrieve images in the form of bytes as follows....

 imageid, imagename, image are the columns for the table images

here we need 3 buttons, 1 file dialog control one image control to display image and store image in DB.

Declare 4 global variables as stated...

        string imageid;
        string imagename;
        SqlDataAdapter da;
        DataSet ds;

In btnSelect_Click to select Image

                FileDialog fldlg = new OpenFileDialog();

                fldlg.InitialDirectory = @":D\"; 

                fldlg.Filter = "Image File (*.jpg;*.bmp;*.gif)|*.jpg;*.bmp;*.gif";   // To select OnlyImages            
                if (fldlg.ShowDialog() == DialogResult.OK)
                    imagename = fldlg.FileName;
                    Bitmap newimg = new Bitmap(imagename);
                    pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
                    pictureBox1.Image = (Image)newimg;
                fldlg = null;
            catch (Exception ex)

In brnsave _Click event

Resize image when uploading (C#)

private Bitmap ResizeImage(Stream streamImage)
    int maxWidth = 200;
    int maxHeight = 400;
Bitmap originalImage = new Bitmap(streamImage);
    int newWidth = originalImage.Width;
    int newHeight = originalImage.Height;
    double aspectRatio =  
(double)originalImage.Width / (double)originalImage.Height;
