Transfer Files With Ftp With Ftpwebrequest?
May 26, 2010
currently I'm working on this ftp transfer. [URL]
I have setup my server computers iis to have a ftp site on port 21 and transfering files works great. But I want to add ftp to a hosted site I got on the server and it's here where I get the problems with connecting. when I try to connect through the command promt I get unknown host error. I have changed the port and open it up in firewall. and even if I could connect how can I decide what folder I want to upload to?

Unfortunately I get an error while uploading:
Invalid URI: Invalid port specified. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.UriFormatException: Invalid URI: Invalid port specified.
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(ftp + ftpFolder + fileName);My FTP-address is:ftp://ftp.mydomain.dk:4001

I have an objective to transfer some files which can be pdf, jpg and xml from one location to another. I am creating a handler based API for that. What could be the best approach for doing it? Should i return a byte array so that the client can pick the byte array and convert it back to file? Also the max file size I need to handle is 18 MB, so i have to make sure that the sizes are properly handled. Should I do an asynchronous transfer for that?

I'm using FtpWebRequest to connect to an FTP server and I can use WebRequestMethods.Ftp.ListDirectoryDetails to list the directory details fine. However the response from the remote server has day, month and time but not year:
-rw-rw-rw- 1 user group 949 Jun 2 08:43 Unsubscribes_20100602.zip
-rw-rw-rw- 1 user group 1773 Jun 1 06:48 export_142571709.txt
-rw-rw-rw- 1 user group 1773 Jun 1 06:50 export_142571722.txt
-rw-rw-rw- 1 user group 980 Jun 1 06:51 export_142571734.txt
This is required for the application I'm writing so I tried to use WebRequestMethods.Ftp.GetDateTimestamp to get the datetimestamp for each file but the response is always empty. No exception is thrown.
try
{
FtpWebRequest ftp = (FtpWebRequest)WebRequest.Create(path);
ftp.Credentials = new NetworkCredential(_ftpUsername, _ftpPassword);
ftp.Method = WebRequestMethods.Ftp.GetDateTimestamp;
try
{
Stream stream = ftp.GetResponse().GetResponseStream();
StreamReader sReader = new StreamReader(stream);
return sReader;
}
catch (Exception exp)
{
throw new Exception(String.Format("An error occured getting the timestamp for {0}: {1}<br />", path, exp.Message));
}
}

I am using :
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://www.contoso.com/test.htm");
request.Method = WebRequestMethods.Ftp.UploadFile;
// This example assumes the FTP site uses anonymous logon.
request.Credentials = new NetworkCredential ("anonymous","janeDoe@contoso.com");
// Copy the contents of the file to the request stream.
StreamReader sourceStream = new StreamReader("testfile.txt");
byte [] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
sourceStream.Close();
request.ContentLength = fileContents.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
For uploading images and songs to the server. But the file is getting corrupted on upload. Normal upload is getting error due to security reason and access issues.
Had to dwell on to ftp. But in this case, file is getting corrupted.

I have a class which implements IHttpHandler that is designed to handle image resize requests. It handles Urls like so [URL] Currently the handler looks for myimg.jpg on disk, cuts a 100x100 thumbnail (if it isn't already present) and redirects the client to the thumbnail like so Response.RedirectPermanent("/some/virtualPath/to/thumbnail.jpg");
This has been working great, but I would like to avoid forcing the client to issue a second HTTP request. Is it safe to do the following? Server.Transfer("/some/virtualPath/to/thumbnail.jpg") All the MSDN documentation talks about using Server.Transfer() to redirect to an aspx page, so I'm not sure if this is the right thing to do or not.

I have written the following code that successful ftps a file to the proper location as long as the file exists on the server itself....
However, I need the code to pull the file contents from the client computer, not the server.
Here is the code:
[Code]....
When I deploy this application to my staging server and test it, it's looking for the files on the staging server...not my local computer.

If I need to redirect a user from one page to another, should I use redirect or go with server.transfer? I'm assuming redirect. The idea is to give the users one specific URL and then have that URL redirect to the most current iteration of the page. For example, the user may have [URL] as the URL but the actual page served to them would be [URL]

I have a listbox control that is databound to a dropdownlist, so when the user selects a value from the dropdownlist, the listbox then displays the corresponding value from the database.
What I now want to do is have the value of the listbox automatically populate another texbox that is databound to something else.
I cant get this to work using the DropDownList_selectedChanged event.

I have written an application that basically gathers up a bunch of text and numerical data from the client PC and stores it as an object. Right now I'm implementing XML serialization so that the file can be saved.
The issue is now, how do I get this data to the server? I have a server running IIS 7 setup but I don't quite understand the ASP.net life cycle, so I'm not sure how to implement the receiving app.

protected void btnCancel_Click(object sender, EventArgs e)
{
Server.Transfer("Fix_Details.aspx");
}
Server.Transfer is not redirecting the page. It stays on the page that the button was clicked on. The message is "Error on Page."I tried Response.Redirect and that didn't work either.

How would I go about sending a int variable, and string variable from one method to another method, to a final third method? This is basically how I have my methods setup. Obviously there is code that runs in each of these, but I am just trying to understand how to transfer these variables to my other methods.
protected void deleteOkBtn_Click(object sender, EventArgs e)
{
remove()
}
protected void imgdelbtn_Click(object sender, EventArgs e)
{
}
public void remove()
{
}

A first chance exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll An exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll but was not handled in user code
After banging my head because i could find where the exception came for and global.asax didn't get hit i found that it's from server.transfer and is a known bug. The alternative i read about is server.execute.However if i do this then the next page fires multiple javascript exceptions and a gridview i have is breaking of and the rows appear half at the left page corner and half inside the gridview!!
For now i just put a try catch on the server.transfer although the exception will not affect the application even if i don't use try catch. I also see that the exception is happening again even if i put try catch but with different dll: A first chance exception of type 'System.Threading.ThreadAbortException' occurred in App_Web_benglxq1.dll An exception of type 'System.Threading.ThreadAbortException' occurred in App_Web_benglxq1.dll but was not handled in user code Now what on earth is benglxq1.dll i don't know. What i know is that i'm leaving an exception to run and i don't like that. This is the js error when i use server.transfer btw: Microsoft JScript runtime error: Sys.ArgumentTypeException: Object of type 'Sys._Application' cannot be converted to type 'Sys._Application'.

I have this code
private void BindSecondaryGrid()
{
DataTable dt = (DataTable)ViewState["SelectedRecords1"];
gridview3.DataSource = dt;
gridview3.DataBind();
}
The selected records from the gridview2 are saved there ViewState["SelectedRecords1"].The columns are id, name, quantity, total. Then these records are saved in gridview3 with
gridview3.DataSource = dt;
gridview3.DataBind();
Now i would like to get these values from gridview3 and store them in a table in my database with same columns of course.Is there a way to do that?

I have a custom error handler in the global.asax's Application_Error method, when an error occurs I use the following code to transfer user to the error page:Server.Transfer("/Error/");
However without specifying the actual page name the code above breaks with "Error executing child request for /Error/" exception.So if I use Server.Transfer("/Error/Default.aspx") it works fine with no problems.Also using Response.Redirect("/Error/") works fine too, however we want to keep using Server.Transfer to retain URL displayed in the address bar when the error page is displayed so users can simply refresh the page to retry accessing the original offending URL.Would be grateful if anyone can comment on how to get the Server.Transfer method working without specifying the actual aspx page name.

have a user control that has a data repeater. When the ItemDataBound even is raised I create a html table which contains a button on each row. The button is created in a seperate class, not in the code behind, so when I attach the button click event I have to put the click method in the class that creates the control. However, when the button is clicked I need to open a modal form in the page that contains the button. How can I move the event back to the web user control with the sender object? I suspect I need to do something with a delegate or something, but I am having a hard time putting how to do that together. Can someone tell me how to do this?
