Uploading Files And Appending Textlines To A Webspace?
Dec 13, 2005
I'm totally new at web-programming and haven't got a clue where to start looking.I'm writing a .NET exe using VB.NET 2003 and it has to do 3 things online.1) it has to read contents of online textfiles (this works, I'm using WebClient)2) it has to upload local textfiles to a webspace (doesn't work 404 error)3) it has to append lines of text to a existing textfile on the webspace (this is not important right now, fix 2 first)What approach do I need to take? I have been unable to find any good articles on this, everyone uses an ASP.NET app, but that cannot be done in my case.

I am trying to import an excel file using asp.net and C#. I found an example in VB, but it is using something called "Server.MapPath" which is not resolving to a namespace. I am on .NET 4.0, C#, and windows XP.I found a "HttpServerUtility.MapPath", but I don't know if this is the equivalent for IIS7?
C#
public OleDbCommand ExcelConnection()
{
string conStr = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + Server.MapPath("~/ExcelImport.xls") + ";" + "Extended Properties=Excel 8.0;";

I am currently creating a FTPWebrequest to handle my uploading (the webrequest section of my function is below). At the moment my code loops through this webrequest section for each file - giving the file path of each file in the string "CompleteLocalPath". For each file it creates a webrequest and giving the required file path, uploading the file using a file stream, and then closing the stream. This works, but seems to take quite a long time. Can you recommend a more efficient way? Perhaps by using one webrequest but modifying the upload path?

I am uploading file to mainframe and before uploading when I open it using notepad I am able to view it.
Once uploaded the administrator is complaining that he is not able to read the data in file and it appears as junk.
Is there anything else I need to do before uploading files to mainframes. I am using Chilkat component to upload the files to mainframes.

I have trying to upload some large files using FTP. Here is the code I am using below.
Private Sub UploadFTP()
' Open file.txt with the Using statement.
Using r As StreamReader = New StreamReader("list.txt")[code]....
I basically loop the above to upload all the files in a specific directory. This works fine with small text files,but when I try uploading a large 30+- mb file it gives me an error.
Quote: The underlying connection was closed: An unexpected error occurred on a receive.
On
cls_stream.Close()
I understand this is caused by .Net not communicating with the server properly? I tried searching all morning to only get confused by all the different methods.

I need to upload a file and rename it. I have found a lot of code that uses the WebRequest for this. I was wondering if there is another method that logs in to the ftp server and will stay connected while I upload files. I am doing this for a webcam application and it seems another method would be quicker than using the credentials each time I need to upload and then rename the file.

I need to upload a large set of files and directories to my web server, all of the files that I want to upload to my server are located in "C:Files_To_Upload" directory, it contains thousands of files and maybe 100 directories/sub directories so I don't want to have to specify each specific sub folder and file - jmcilhinney's ftp example which I am currently working with shows a way to upload all of the files from a specific directory, but not subfolders and their files. How can I get it to also upload the sub folders and their files?
Code I am using based on jmcilhinney's threaded ftp example:
Private Sub UploadFolder(ByVal source As String, ByVal destination As String)
For Each file As String In IO.Directory.GetFiles(source)
Threading.ThreadPool.QueueUserWorkItem(AddressOf UploadFile, _

I need to upload multiple files in a winforms application. So far I've been using a webclient and while this is working fine I'm wondering if there is a better way for doing this. Does the webclient make a new connection for every request or does the connection persists between uploads?
Dim Ftpclient As New System.Net.WebClient()Ftpclient.Credentials = New System.Net.NetworkCredential(username, password)
Dim Files As New Dictionary(Of String, String)Fill dictionary with items for upload here
For Each RemoteFile As String In Files.Keys Ftpclient.UploadFile(RemoteFile, Files(RemoteFile))Next

I am trying to add multiple files to FTP server by dragging and dropping and I am able to do that using try catch block and if we give the ftp settings correctly it takes 1 sec to upload them but when we give wrong details it hangs up and dosen't give me any error message though If I give an exceptional message.
Now I am getting error message as well as success message for every file I add.I do not want that to be happen.where should I give messages for success and failure so that it should take few seconds for uploading and if not should give me a message immediately.
Here is my code:
Private Sub uploadFile(ByVal FTPAddress As String, ByVal filePath As String, ByVal username As String, ByVal password As String) 'Create FTP request

I am trying to use and display calculations from various text fields, however it is appending the values. I think it has to do with it being a String Variable and not a Value.. here is the code
Private Sub btnTransact_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTransact.Click
If rb1Deduct.Checked = True Then txtp1Amt.Text = (txtp1Amt.Text - txtTransact.Text)

I have a list of file names and there locations as follows:
c:ICTAUTOCAD_2010Customisations2009040920090409.lsp

OFFSET.lsp c:ICTAUTOCAD_2010CustomisationsLockDWGLSPLockDWG.lsp
c:ICTAUTOCAD_2010LSPacad2010doc.lsp
The list is very basic but should be appended to say:
(load "c:ICTAUTOCAD_2010Customisations2009040920090409.lsp")
(load "c:ICTAUTOCAD_2010CustomisationsAdvanced OffsetLSPADVANCED OFFSET.lsp")
(load "c:ICTAUTOCAD_2010CustomisationsLockDWGLSPLockDWG.lsp")
(load "c:ICTAUTOCAD_2010LSPacad2010doc.lsp")

How would I go about appending text to a Textbox without losing the current scrollbar position? I thought somehting as simple as:
Textbox1.Text += "MyString" & vbCrLf
would work, but it just sends the scrollbars to the top.

This append feature does not seem to work. I've looked in many places to no avail. The other examples below for writing and reading seem to be going fine.

I am trying to save the contents of a richtextbox to a text file. I know that they .SaveFile method automatically overwrites the existing file so I have a routine that will load the contents of the file into a temporary rich textbox control then append the new information to that and then save from the temp richtextbox. My application works as I want it to on my workstation but I cannot get it to work correctly on the notebook computer it will be running on from now on. It only works when I put in a breakpoint and I am not sure why?
[Code]...
If I put breakpoints on any of the lines rtb.Select, rtb.Copy, rtb.Paste then it works. I even tried putting a Thread.sleep before saving, thinking that more was needed to do the copy/paste but that didnt work either.

Lets assume I have a DataSet that contains the following info (columns seperated with | character):
1 | Logan | Young
2 | John | Doe
3 | Jane | Doe
4 | Joe | Soap
If I now write this info to a text file, but later want to append 5 | Susan | Sarandonto the end of the text file, I obviously want to check that the text file doesn't already contain the data that I want to append to it. I'm having a little difficulty figuring out how to perform this check...I know you'd have to loop through every row in the DataSet's table and compare it to every line in the text file. That part's easy.

I haven't yet tried, but would the data append to the dgv if i just called this again using query and removing the queryTotal variable? seem to think they behave like that from past tests?
