Filename overwrites the uploaded attachments

The file name is generated by Po+Invoice in the sql table. When user attach a pdf it overwrites the existing file name that has same po+invoice. Is there anyway i could create the unique id filename.
public partial class upload : System.Web.UI.Page
{
string mID;
DataBaseDataContext dataBaseDataContext = new DataBaseDataContext();
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnExit_Click(object sender, EventArgs e)
{
Response.Redirect("Default.aspx");
}
protected void SUbmit(object sender, EventArgs e)
{
try
{
var ext = FileUploadtoServer.FileName.Substring(FileUploadtoServer.FileName.IndexOf('.') + 1, 3);
if (ext.ToLower() != "pdf")
{
Response.Write("<script>alert('Please select a pdf File!')</script>");
return;
}
}
catch (Exception ex)
{
Response.Write("<script>alert('Please select a pdf File!')</script>");
return;
}
if (PO_Number.Text.Equals("") || HeadCode.Text.Equals("") || Manufacture.Text.Equals("") || Description.Text.Equals("") || Invoice.Text.Equals(""))
{
Response.Write("<script>alert('Please Fill All Fields!')</script>");
}
TPT tPT = new TPT();
tPT.Invoice_No = Invoice.Text;
tPT.PO_Number = PO_Number.Text;
tPT.Item_Code = Manufacture.Text;
tPT.Heat_Code = HeadCode.Text;
tPT.Description = Description.Text;
tPT.FileName = PO_Number.Text + Invoice.Text + ".pdf";
dataBaseDataContext.TPTs.InsertOnSubmit(TPT);
dataBaseDataContext.SubmitChanges();
String path = Server.MapPath("Attachments/" + PO_Number.Text + Invoice.Text + ".pdf");
FileUploadtoServer.SaveAs(path);
Response.Write("<script>alert('Successfully Inserted!')</script>");
Invoice.Text = "";
Manufacture.Text = "";
HeadCode.Text = "";
Description.Text = "";
PO_Number.Text = "";
}
}
I have tried
Guid.NewGuid() + ".pdf";,
it still does the same thing.

The simple way would be to just take the file name, and add -1, then -2, then -3
So,
mydoc.pdf
mydoc-1.pdf
mydoc-2.pdf
etc. etc.
So, then say a function like this:
Edit: Updated code
string GetServerFilenext(string strFileFullPath)
{
string strFileToCheck = "";
for (int i = 0; i < 100; i++)
{
if (i == 0)
strFileToCheck = strFileFullPath;
else
strFileToCheck =
Path.GetDirectoryName(strFileFullPath) +
#"\" + Path.GetFileNameWithoutExtension(strFileFullPath) +
"-" + i.ToString() + Path.GetExtension(strFileFullPath);
if (!File.Exists(strFileToCheck))
break;
}
return strFileToCheck;
}
So, now your code becomes this:
string sFileToSave =
Server.MapPath(#"~/Attachments/" + PO_Number.Text + Invoice.Text + ".pdf");
sFileToSave = GetServerFileNext(sFileToSave);
tPT.FileName = Path.GetFileName(sFiletoSave);
So, you setup the full path and file name.
You then check if it exists, and if not, then add -1, then -2 etc. etc.
Edit2: So, code would look like this (warning: air code)
string sFileToSave =
Server.MapPath(#"~/Attachments/" + PO_Number.Text + Invoice.Text + ".pdf");
sFileToSave = GetServerFileNext(sFileToSave);
TPT tPT = new TPT();
tPT.Invoice_No = Invoice.Text;
tPT.PO_Number = PO_Number.Text;
tPT.Item_Code = Manufacture.Text;
tPT.Heat_Code = HeadCode.Text;
tPT.Description = Description.Text;
tPT.FileName = Path.GetFileName(sFileToSave);
dataBaseDataContext.TPTs.InsertOnSubmit(TPT);
dataBaseDataContext.SubmitChanges();
FileUploadtoServer.SaveAs(sFileToSave);

Instead of adding -1,-2, i was able to upload it by adding date stamp
`tPT.FileName = PO_Number.Text + Invoice.Text + DateTime.Now.ToString("yyyyMMddHHmmss") + ".pdf";`

c# - How to call/link a workflow on a web application from a c# program?

I have a C# (WinForms) application that can scan documents via a printer. After scanning, I will be able to enter document details on it and have a button to finalize the documents. The documents details and info will be stored in my database ABC in certain tables.
Now, I have another web application written in Java(IntelliJ) that has some button functionality to upload documents and then start a workflow and route it to another user to approve the document. I won't go into detail on the specifics. This application also connects to the same database ABC.
So now comes the tougher part, I need to link these two applications in a way that when I finalize my document
on the C# application, it has to auto trigger the workflow on the web application side. Rather than manually starting the workflow on the web application, it would just call or trigger the workflow, so I do not need to access the web application at all for the process to start.

Is there a way I could call this from the C# application?

You can send your file directly from your C# app with use of Http client. Here is code sample:
private async Task<bool> Upload(string filePath)
{
const string actionUrl = #"http://126.32.3.178:8111/process/taskmanager/start/start.jsp";
var fileName = Path.GetFileName(filePath);
var fileBytes = File.ReadAllBytes(filePath);
var fileContent = new ByteArrayContent(fileBytes);
using (var client = new HttpClient())
using (var formData = new MultipartFormDataContent())
{
formData.Add(fileContent, fileName);
var response = await client.PostAsync(actionUrl, formData);
return response.IsSuccessStatusCode;
}
}
Also, note that there maybe some sort of authentication should be performed before you can post a request.

LinQtoExcel using asp fileupload

im having problems with this function. so basically a user will upload an excel file .xls (2003 version) then once the import button is clicked it will read the excel file and import it into the sql database.
here is my code
protected void btnImport_Click(object sender, EventArgs e)
{
Business.Student student = new Business.Student();
int errorCount = 0;
int successCount = 0;
string successTotal;
int missinglastname = 0;
int missingfirstname = 0;
int missingmiddlename = 0;
if (filebiometrics.HasFile == false)
{
}
else
{
string pathToExcelFile = filebiometrics.FileName;
var excelFile = new ExcelQueryFactory(pathToExcelFile);
IEnumerable<string> worksheetnames = excelFile.GetWorksheetNames();
string worksheetName = excelFile.GetWorksheetNames().ToArray()[0];
var import = from a in excelFile.Worksheet<Business.Student.StudentList>(worksheetName) select a;
//var emptyfield = excelFile.Worksheet<Business.Employees.EmployeeImport>().Where(x => x.Surname != null).ToList();
excelFile.AddMapping<Business.Student.StudentList>(x => x.studentnumber, "Student Number");
excelFile.AddMapping<Business.Student.StudentList>(x => x.firstname, "Firstname");
excelFile.AddMapping<Business.Student.StudentList>(x => x.lastname, "Lastname");
excelFile.AddMapping<Business.Student.StudentList>(x => x.middlename, "Middlename");
string missing = "Missing!";
foreach (var a in import)
{
if (a.studentnumber == 0)
{
}
if (a.lastname == null)
{
a.lastname = missing;
missinglastname = missinglastname + 1;
}
if (a.firstname == "")
{
a.firstname = missing;
missingfirstname = missingfirstname + 1;
}
if (a.middlename == null)
{
missingmiddlename = missingmiddlename + 1;
}
else if (student.CheckExistingStudentNumber(a.studentnumber))
{
errorCount = errorCount + 1;
}
else
{
student.Create(a.studentnumber, a.firstname, a.lastname, a.middlename);
successCount = successCount + 1;
successTotal = "Total imported record: " + successCount.ToString();
}
}
txtLog.InnerText = "Total duplicate record: " + errorCount.ToString() +
Environment.NewLine +
"Total missing data on Firstname column: " + missingfirstname.ToString() +
Environment.NewLine +
"Total missing data on Lastname column: " + missinglastname.ToString() +
Environment.NewLine +
"Total missing data on middlename column: " + missingmiddlename.ToString() +
Environment.NewLine +
Environment.NewLine +
"Total imported record: " + successCount.ToString();
filebiometrics.Attributes.Clear();
}
}
im always getting this error
the error is in this line 'IEnumerable worksheetnames = excelFile.GetWorksheetNames();'
can somebody help me with this?

Your error message is self explanatory. Error is at this line:-
var excelFile = new ExcelQueryFactory(pathToExcelFile);
ExcelQueryFactory expects the full file path but you are just passing the excel file name using string pathToExcelFile = filebiometrics.FileName; and obviously it is not able to read the file.
You need to read the excel file which user is uploading and save it to the server and then read it like this:-
string filename = Path.GetFileName(filebiometrics.FileName);
filebiometrics.SaveAs(Server.MapPath("~/") + filename);
var excelFile = new ExcelQueryFactory(Server.MapPath("~/") + filename);

I need to rebind in Grid-view after every record completed in for loop process?

I try to import the records from csv and binding into grid.Then every records process for other details. In this case I need to update the UI after every record completed.

Folder Watch when File is Created

im writing a code in C# that watches a folder and when a file gets created the code makes some actions and writes the results to a log file.
im having this very strange behaviour. when i file gets created in the watched folder the function that handles the change is executed twise! even if it is only one change event.
initially i used FileSystemWatcher. but i after looking it up, i saw that it has meny stability issued so i switched to MyFileSystemWatcher which is a much more stable impliminatation. but im still getting duplications in my log file. i have no idea why the code that is in chanrge for looking up the change runs twise. here is the code sample
protected void Folder_Watch(string path)
{
if (!Directory.Exists(path))
{
try
{
System.IO.Directory.CreateDirectory(path);
}
catch (Exception ex)
{
File.AppendAllText(logPath + "\\SSHErrorLog.log", "[]*******" + DateTime.Now + " Error: " + ex.Message.ToString() + Environment.NewLine);
}
}
MyFileSystemWatcher m_Watcher = new MyFileSystemWatcher(path);
//m_Watcher.Path = path;
m_Watcher.Filter = "*.*";
m_Watcher.NotifyFilter = NotifyFilters.FileName;
m_Watcher.Created += new FileSystemEventHandler(OnChanged);
m_Watcher.EnableRaisingEvents = true;
}
here is the onChange function
private void OnChanged(object source, FileSystemEventArgs e)
{
File.AppendAllText(logPath + "\\SSHConnectionLog.log", "[]*******" + DateTime.Now + " OnChanged function: " + Environment.NewLine);
// Decrypt the file.
DecryptFile(keyPath + "\\id_rsa_Encrypted", keyPath + "\\id_rsa", sSecretKey);
// Remove the Key from memory.
//PKey = new PrivateKeyFile(keyPath + "\\id_rsa");
keyResult.Text = "RSA keys Were Generated at:" + keyPath;
//ScpClient client = new ScpClient("remnux", "adi", PKey);
Chilkat.SFtp client = new Chilkat.SFtp();
string[] tempPath = e.FullPath.Split('\\');
string fullPathNew = string.Empty;
for (int i = 0; i < tempPath.Length - 1; i++)
{
fullPathNew += tempPath[i];
}
if (Directory.Exists(fullPathNew))
{
sshConnect(client);
File_Upload(e.FullPath, client);
}
else
{
try
{
sshConnect(client);
System.IO.Directory.CreateDirectory(fullPathNew);
File_Upload(e.FullPath, client);

{
File.AppendAllText(logPath + "\\SSHErrorLog.log", "[]*******" + DateTime.Now + " Error in OnChanged function: " + ex.Message.ToString() + Environment.NewLine);
