Setting Image for BunifuPictureBox
Apart from the normal way of setting an image from a resource - here are a few ways to set BunifuPictureBox Image.
- From Url
- From Database
From Url
This can be achieved by using two methods
- WebClient
System.Net.WebClient webClient = new System.Net.WebClient();
//Download and save your file on form load or button click - whichever you like
webClient.DownloadFileAsync(new Uri("http://scottdavidoff.com/images/davidoff-portrait.square.hi-res.jpg"), "image.jpg");
//create an event
webClient.DownloadFileCompleted += WebClient_DownloadFileCompleted;
// set the image when the file download is completed
private void WebClient_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e)
{
//set your image
bunifuPictureBox1.Image = Image.FromFile("image.jpg");
}
You can also set an Image directly by loading
From database
You can achieve this by using this code assuming you have your images saved in pictures table and a field called image and getting them using id value
{
using (var conn = new MySqlConnection(ConnectionString))
using (var cmd = conn.CreateCommand())
{
conn.Open();
cmd.CommandText = "SELECT image FROM pictures WHERE id = ?id";
cmd.Parameters.AddWithValue("?id", id);
using (var reader = cmd.ExecuteReader())
{
if (!reader.Read())
{
return null;
}
const int CHUNK_SIZE = 2 * 1024;
byte[] buffer = new byte[CHUNK_SIZE];
long bytesRead;
long fieldOffset = 0;
using (var stream = new MemoryStream())
{
while ((bytesRead = reader.GetBytes(reader.GetOrdinal("image"), fieldOffset, buffer, 0, buffer.Length)) == buffer.Length)
{
stream.Write(buffer, 0, (int)bytesRead);
fieldOffset += bytesRead;
}
conn.Close();
return Image.FromStream(stream);
}
}
}
}
and then just set your image
bunifuPictureBox1.Image = = GetImage("1");
