Hi,
You can actually create a windows service with filesystemwatcher, which keeps watching the creation of any new text files.
The code within the windows service looks something similar to the below:
Protected Overrides Sub OnStart(ByVal args() As String)
InitializeEventLog()
InitializeFileWatcher()
InitializeMailServer()
End Sub
In the InitializeFileWatcher, specify the ftp folder path and add an event handler,
Private Sub InitializeFileWatcher()
fsWatcher = New FileSystemWatcher
fsWatcher.Path = "\\FTP\Folder\*.txt"
fsWatcher.NotifyFilter = (NotifyFilters.DirectoryName Or NotifyFilters.FileName)
fsWatcher.IncludeSubdirectories = True
'watcher.NotifyFilter = NotifyFilters.FileName
'watcher.NotifyFilter = NotifyFilters.DirectoryName
' Only watch text files.
fsWatcher.Filter = "*.txt"
' Add event handlers.
AddHandler fsWatcher.Created, AddressOf OnTextFileCreated
' Begin watching.
fsWatcher.EnableRaisingEvents = True
End Sub
so, in the OnTextFileCreated sub procedure, load the data from text file to the local server
Private Sub OnTextFileCreated(ByVal source As Object, ByVal e As FileSystemEventArgs)
'Code for loading text data to local server-database
End Sub
So, whenever there are new text files created in the specified FTP folder, the event is raised and the text file data is loaded to the server.

hi
i want to copy data of one table to another table
and get backup from database
my database is access
i dont find any sample about it
please help me
|
|

Do you want to copy data to another table inside the existing database or back it up to a separate database? Are you simply going to append the data to a table whose structure has been defined in a prebuilt database or do you need to create the database and it's tables from scratch?
More info needed before we can help.

I have a question that I was hoping someone could help me with. I am using VB.net 2005 express edition with SQL Server 2005 Express edition.
I have a database that has a table in it called Folder. It consists of two fields. One is called folderId and folderName.
I want to add a new row to this folder by calling a second form from my main form. For example, say I open up a second form from my main form. This second form consists of a text box and an button called OK. The user will enter the new folder name into the text box. How do I make it so the name the user enters into the text box is added to the folder table.

Best way to do it IMHO is through making use of datasets and table adapters.
First you need to create a dataset. To do this
1. Right click over your solution name and select "Add new item..."
2. Click on "Dataset" & give the dataset a meaningful name (in this example I'm using the name dsFolder).
3. The dataset will be created and a wizard will open to help you configure your table adapter.
4. Configure your table adapter to use the same connection string (saved in the My.Settings file), click "Next" & use the query builder to add your table to the table adapter.
5. Add the fields from your table by checking their checkboxes. Remember to include the primary key from your table so that the table adapter can automatically generate update statements for you.
6. Click "Next" & "Finish".
In your main form add this code to whatever event it is that opens your form:
Dim frm2 as New Form2
frm2.Show()
'use ShowDialog() if you don't want users to close
'the form before completing process.
Then in your second form add
Option Strict On
Imports System.Data
Imports System.Data.SqlClient
to the very top of the code editor. Add the code below to the OK button's click event (the naming in your code will probably be different but you get the idea),
Private Sub btnOK_Click(...)Handles btnOK.Click
'create new datasets and table adapters
Dim dsFolder1 As New dsFolder
Dim daFolder As New dsFolder.FolderTableAdapter
'create a new row to add to the table
Dim dr As DataRow = dsFolder1.Folder.NewRow()
'try updating the database
Try
dr("folderName") = txtFolder.Text
'add the datarow to the dataset
dsFolder1.Folder.Rows.Add(dr)
'update the database
daFolder.Update(dsFolder1)
Catch ex As Exception
Messagebox.Show(ex.Message)
End Try
End Sub
Using this kinda practice is better because the datasets and table adapters add type safety to your code, make it more readable as well as gives you objects that you can reuse later on in your code. This comes in really useful when you work on large databases.
Also. make use of Try...Catch...End Try blocks. The structured error handling ability of .NET is tool worth using. You could go even further by implementing TraceListeners to write out performance data & errors from your code to a log file, which can only help you write better code.
Sorry, for the long-winded explanation, I've had WAAAAY too much coffee this morning...

kulazfuk,
Thanks you so very much for your help. I was playing with something like this last night, but you clued me in on some other ideas. Thank you very much.
It still is not working for me though. I could not create a table adapter with the line
Dim daFolder As New dsFolder.FolderTableAdapter
I used Dim daFolder As New FolderTableAdapters.FolderTableAdapter
Everything else is the same, but it does not work.
|
|
|
|
|
Well, like I said before your naming conventions will probably be different so what you gotta look at is creating a table adapter for the dataset that you previously created. it'll follow a Dim VariableName As New DatasetTableAdapter.TableName type pattern.
That should sort you out.

Hi,
May i know how to uncheck the show clock in taskbar properties when my system on loading.
|
|
|
|
|
You have to use the Win32 API for that.
|
|
|
|
|
That doesn't look like a complete connection string, but the method might add things to it before it uses it. Look up the documentation for the method to see what it expects.

b { font-weight: normal; }

No, a DSN is a Data Source Name. A DSN can be a User DSN or a Machine DNS, and contains settings for a database connection. You access the data sources from Administrative Tools in the start menu.

Hi I am using vb.net2003,
Does anyone know any code I can use to delete files in a folder as well as the folder the files are located in?
Thanks for any help
|
|
|
|
|
You need to manually delete the files first. Directory.GetFiles will give you a list of files to delete.
Christian Graus - Microsoft MVP - C++
Metal Musings - Rex and my new metal blog
|
|
|
|
|
To delete files, use: My.Computer.FileSystem.DeleteFile("C:\File_To_Delete.txt")
You can also select whether you want the file you are deleting to goto the recycle bin or just to be permanantly deleted. Just use:
My.Computer.FileSystem.DeleteFile("C:\File_To_Delete.txt", FileIO.RecycleOption.DeletePermanently)
|
|
|
|
|
try this
imports system.io
Dim objDir As New DirectoryInfo("C:\testdel")
objDir.Delete(True)

I am using VB.net 2005 express and I have created a dataset with SQL server 2005 express. I want to use that dataset to load the nodes in a treeview control. The dataset consists of two tables one is called the State table and the other is called the City. I want the State table to be parent nodes and the corresponding city table rows to be child nodes beneath it. Does some know how to do this?
Thanks.
