Insert function is properly working but the update is not. I am really struck in here. If you have better way to insert & update a image field please explain.

First of all move your answer to your question. Its not an answer. Its just a new question.
try using the following, I personally update images as follows;
Image img = Image.FromFile(#"C:\Users\Awais\Desktop\image.png");
byte[] arr;
using (MemoryStream ms = new MemoryStream())
{
img.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
arr = ms.ToArray();
}
int dr = 0;
SqlConnection con = new SqlConnection("data source=.; initial catalog=database; uid=sa;pwd=password;");
SqlCommand cmd = new SqlCommand("update table set I1 = #img", con);
cmd.Parameters.AddWithValue("#img", arr);
con.Open();
using (con)
{
dr = cmd.ExecuteNonQuery();
}

Issues with Repeater going through each item

I am having issues with looping through my repeater to save all the data. If I have 30 items in the repeater it will go through the repeater 30 times. However the ID never is updated. I set the id to textbox so I know the value is correct with DB and not duplicated.
Here i the code.
protected void Save()
{
foreach (RepeaterItem RI in Repeater1.Items)
{
bool budgetvalue = CBBudgeted.Checked;
//lblHeader.Text = rs["BudgetYear"].ToString();
string Janbudget = txtJanBudget.Text;
string Febbudget = txtFebBudget.Text;
string Marbudget = txtMarBudget.Text;
string Aprbudget = txtAprBudget.Text;
string Maybudget = txtMayBudget.Text;
string Junbudget = txtJunBudget.Text;
string Julbudget = txtJulBudget.Text;
string Augbudget = txtAugBudget.Text;
string Sepbudget = txtSepBudget.Text;
string Octbudget = txtOctBudget.Text;
string Novbudget = txtNovBudget.Text;
string Decbudget = txtDecBudget.Text;
string PriceEach = txtPriceEach.Text;
string IDnum = txtID.Text;
string saveStaff = "Update sales_budget " +
"set Janbudget " + Janbudget +
", Febbudget " + Febbudget +
", Marbudget " + Marbudget +
", Aprbudget " + Aprbudget +
", Maybudget " + Maybudget +

", Octbudget " + Octbudget +
", Novbudget " + Novbudget +
", Decbudget " + Decbudget +
", Budget " + budgetvalue +
", Price_Each " + PriceEach +
" Where id = " + IDnum;
GetConnection Sales = new GetConnection();
string conn = Sales.SalesConnect;
SqlCommand querySaveStaff = new SqlCommand(saveStaff);
using (System.Data.SqlClient.SqlConnection con = new System.Data.SqlClient.SqlConnection(conn))
{
System.Data.SqlClient.SqlCommand command = new System.Data.SqlClient.SqlCommand(saveStaff, con);
con.Open();
try
{
command.ExecuteNonQuery();
}
catch
{
//GetConnection Sales = new GetConnection();
// string conn = Sales.SalesConnect;
// using (System.Data.SqlClient.SqlConnection con = new System.Data.SqlClient.SqlConnection(conn))
// {

// con.Open();
// System.Data.SqlClient.SqlDataReader rs = command.ExecuteReader();
// while (rs.Read())
}
con.Close();

How i can delete database from local server without database files

If database files .mdf and .log do not exist in folder with application then i need to create new database, but if i do like this
CREATE DATABASE Mydvds.mdf
And i have exception that databese Mydvds.mdf is alredy exist. If i try to drop database like this
DROP DATABASE Mydvds.mdf
I have exception that base is not exist or i don't have premmisions.
I was checking database list by way of
SELECT * FROM sysdatabases
And C:\Mydvds.mdf in this list.
How i can remove this database from server?
Or can you tell me about another way do this?
public void create_db()
{
string base_path = Environment.CurrentDirectory + #"..\..\..\My_cool_db.mdf";
string log_path = Environment.CurrentDirectory + #"..\..\..\My_cool_db_log.ldf";
string ConnectionString = #"Data Source=(LocalDB)\v11.0";
string cmnd_create_db;
connection = new SqlConnection(ConnectionString);
cmnd_create_db = "CREATE DATABASE My_cool_db ON PRIMARY " +
"(NAME = My_cool_db, " +
"FILENAME = '" + #base_path + "', " +
"SIZE = 4MB, MAXSIZE = 20MB, FILEGROWTH = 10%) " +

{

How can i get the rotated image in file

as of now i can upload my image in the database the problem is when i rotate the image.
the uploaded image is not the rotated one, its still the image that i upload that i didnt rotate.
how can i upload the rotated image ?
Stream FileStream = File.OpenRead(ServerPath + Filename);
// Stream FileStream = FileUpload1.PostedFile.InputStream;

objImage = ScaleImage(PostedImage, 73);
if (FileType != "jpg" && FileType != "JPG")
{
objImage.Save(ServerPath + jpgFileName, ImageFormat.Jpeg);
}
else
{
//objImage.Save(ServerPath + Filename);
}
img = new byte[FileStream.Length];
contentlength = FileStream.Length;
if (contentlength > 506000)
{

First of all make sure that your file is saved on the disk and then save the file into DB.
If this will not help you probably will have to either:
rotate it properly, rotation might be saved only by the image viewer without changing the image on the disk, i have encountered the issue with Picassa
rotate it in the code (rotate bytes)

code ignored after first button click

This button (loginButton) does everything it's supposed to on the first click. Then, on all subsequent clicks, it refuses change the text of loginStatusLabel at the beginning and end of the method...why? It's as if the code is completely skipped over for with no explanation. The debug messages before and afterword both come through fine, and loginStatusLabel isn't referenced anywhere else.
Am I an idiot?

Forgot to create the new thread in the first place. I'm stupid.
