Question

Hi all,

 

   Iam creating back up file of ms-access database code working fine when i use FolderBrowserDialog box but i want back up should store automatically when i close form for specific directory  

 

i'm tried below code but its not working

public void create_Directory()

{

 

String Application_Folder = @"D:\Medical_reports";

if (!Directory.Exists(Application_Folder))

{

Directory.CreateDirectory(Application_Folder);

}

 

string Back_UP = Path.Combine(Application_Folder, "Back_UP");

if (!Directory.Exists(Back_UP))

{

Directory.CreateDirectory(Back_UP);

}

 

} 

 

private void Login_Page_FormClosing(object sender, FormClosingEventArgs e)

{

 

create_Directory();

string file_name = @"\Medical.accdb";

StreamWriter sw = new StreamWriter(file_name);

sw.Write(sw.ToString());

sw.Close();

} 

 

 

//this code working fine but i dont want to open dialog box  

FolderBrowserDialog fbd = new FolderBrowserDialog();

if (fbd.ShowDialog() == DialogResult.OK)

{

 string PathtobackUp = fbd.SelectedPath.ToString();

 File.Copy(CurrentDatabasePath, PathtobackUp + @"\Medical.accdb", true);

 MessageBox.Show("Back Up SuccessFull! ");
