On the tail end of database backup project and I've run into a issue where the Deflate compression I put in can't seem to find the path I saved the backup to. Being that the default backup location (used here) is on a network drive is there something else I need to do to make sure the path is found by Deflate? As of now I get System.IO.DirectoryNotFoundException: 'Could not find a part of the path. The purpose of the tool is to be able to put in any server you want to access, get a list of available DB's and then choose the one you want to backup.
I had this issue before locally, but all i had to do was give SQLserver the proper permissions to the folder.
using (SqlConnection newConn = new SqlConnection(connString))
using (SqlCommand sqlCmd = new SqlCommand(query, newConn))
{
newConn.Open();
value = sqlCmd.ExecuteScalar();
canCompress = !(value == null || Convert.ToInt32(value) == 0);

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();
}
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?

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 ?

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)
I want to create a backup for the database I worked on my application by C# statement.
This is my code:
SqlConnection con = new SqlConnection(Connection.GetConnection());
SqlCommand command = new SqlCommand();
command.CommandText = "backup database [Pharmacy Database]to disk ="+"'"+path +"'";
command.CommandType = CommandType.Text;
command.Connection = con;
con.Open();
command.ExecuteNonQuery();
con.Close();
And gives me an error:
Cannot open backup device 'C:/Users/Abo Sala7/Desktop'.Operating system error 5 (failed to retrieve text for this error. Reason:15105).
BACKUP DATABASE is terminating abnormally.
Maybe the Problem is that your ServiceUser of the SQL-Service does not have the permission to write into the defined folder - The service is perfoming the backup - so this user must have the requiered permissions on the destination folder. (error 5 == Accessdenied)
I have been using the code below for back up, try this.

My fileupload isnt creating the path if its not there, its only working if the folder belonging to the user id is actually already in place, I need it to upload whether the folder is there or not.

string filenameDB = Path.GetFileName(FileUpload1.FileName);
string fileuploadpath = Server.MapPath("~/userdata/" + theUserId + "/uploadedimage/") + Path.GetFileName(FileUpload1.FileName);

}
}
}
}
Why don't you simply check if the folder is already created, if it's not create it. if(System.IO.Directory.Exists("YourDirectoryPath")) do your stuff;
The command you want to utilize is
string fileuploadDir = Server.MapPath("~/userdata/" + theUserId + "/uploadedimage/");
if(!System.IO.Directory.Exists(fileuploadDir)
{
System.IO.Directory.CreateDirectory(fileuploadDir)
}
Insert this after:
string fileuploadpath = Server.MapPath("~/userdata/" + theUserId + "/uploadedimage/") + Path.GetFileName(FileUpload1.FileName);
Corrected based on comments below.
string dirPath= Path.GetDirectoryName(fileuploadpath);
if(!Directory.Exists(dirPath))
{
Directory.CreateDirectory(dirPath);
}
