Hi,
I have a windows form with a "ComboBox" on it. The "ComboBox" has the words "Production" and "Development" in it. If the user selects "Production", I need my C# code to point to the Production database. If the user selects "Development", I need my C# code to point to the Development database. Can someone please tell me how to do this?
Sorry, I'm still not sure what to do. I am new to C#, so it is confusing. Here is my code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Runtime.InteropServices;
using Microsoft.Win32.SafeHandles;
using System.Data.SqlClient;
using System.Data.SqlTypes;
namespace GEOINT
{
public partial class frmForm : Form
{
public frmForm()
{
InitializeComponent();
}
//Insert using Filestream, file into SQL Server Table
private void btnInsert_Click(object sender, EventArgs e)
{
OpenFileDialog openFileDlg = new OpenFileDialog();
openFileDlg.InitialDirectory = Directory.GetCurrentDirectory();
if (openFileDlg.ShowDialog() == DialogResult.OK)
{
FileInfo fi = new FileInfo(openFileDlg.FileName);
FileStream fs = new FileStream(fi.FullName, FileMode.Open, FileAccess.Read);
BinaryReader rdr = new BinaryReader(fs);
byte[] fileData = rdr.ReadBytes((int)fs.Length);
rdr.Close();
fs.Close();
string cs = @"server=JITC-PC\GEOINT;database=DEV_GEOINT;integrated security=SSPI";
using (SqlConnection con = new SqlConnection(cs))
{
con.Open();
string sql = "INSERT INTO Filestream_Files (Row_Guid_Col_ID, fData, fName) VALUES (default, @fData, @fName)";
SqlCommand cmd = new SqlCommand(sql, con);
cmd.Parameters.Add("@fData", SqlDbType.Image, fileData.Length).Value = fileData;
cmd.Parameters.Add("@fName", SqlDbType.NVarChar).Value = fi.Name;
cmd.ExecuteNonQuery();
con.Close();
}
MessageBox.Show(fi.FullName, "Selected Document/Picture Inserted!", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
private void btnExit_Click(object sender, EventArgs e)
{
this.Close();
}
private void frmForm_Load(object sender, EventArgs e)
{
}
//Load LAST selected file to SQL Server table
private void btnRetrieve_Click(object sender, EventArgs e)
{
string cs = @"server=JITC-PC\GEOINT;database=DEV_GEOINT;integrated security=SSPI";
using (SqlConnection con = new SqlConnection(cs))
{
con.Open();
SqlTransaction txn = con.BeginTransaction();
string sql = "SELECT fData.PathName(), GET_FILESTREAM_TRANSACTION_CONTEXT(), fName fID FROM Filestream_Files WHERE fID = (SELECT MAX(fID)FROM Filestream_Files)";
SqlCommand cmd = new SqlCommand(sql, con, txn);
SqlDataReader rdr = cmd.ExecuteReader();
while (rdr.Read())
{
string filePath = rdr[0].ToString();
byte[] objContext = (byte[])rdr[1];
string fName = rdr[2].ToString();
SqlFileStream sfs = new SqlFileStream(filePath, objContext, System.IO.FileAccess.Read);
byte[] buffer = new byte[(int)sfs.Length];
sfs.Read(buffer, 0, buffer.Length);
sfs.Close();
//Files in the table have been written to a directory for viewing.
//string filename = @"C:\Development\Geoint\Geoint\bin\debug;
string filename = fName;
System.IO.FileStream fs = new System.IO.FileStream(filename, FileMode.Create, FileAccess.Write, FileShare.Write);
fs.Write(buffer, 0, buffer.Length);
fs.Flush();
fs.Close();
}
rdr.Close();
txn.Commit();
con.Close();
}
}
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
}
}
}
thanks,
Sharon
