My goal is to upload a string to a txt file on an ftp server.Here is what I have found so far:
vb
Dim clsRequest As System.Net.FtpWebRequest = _
DirectCast(System.Net.WebRequest.Create(RemoteFilename), System.Net.FtpWebRequest)
clsRequest.Credentials = New System.Net.NetworkCredential("usr", "pw")
[code]....
Is there a way to convert a String into something that clsStream.Write will accept?
I'm trying to write a file in chunks in a loop but the filestream.write just causes the sub to end the second time round but the first chunk it written and the savefiledialog remains?
edit: I was using an offset which I shouldn't have so now it writes the file just fine but the savefiledialog doesn't close itself?
can someone help explain to me how this code knows where to write the file too? I want to modify it to write another schema file to a different folder location [code]I need to write the 2nd schema to j:Solds folder but dont know how to get it to the folder it writes to just.[code]I know how to re-write this with streamWriter but I am looking to understand how this piece of code actually knows the location to write too
View 4 RepliesThe goal is to write data to a SQL Server 2008 FILESTREAM file using VB.Net. An "Access Denied" message occurs when creating a FileStream object in the code(see red underlined code below). SQL Server 2008 is configured to "Allow remote clients to have streaming access to FILESTREM data" along with "Enable FILESTREAM for Transaction-SQL access"... What configuration setting is missing and causing the "Access Denied" message? Figure 1.) Code used to stream data to SQL Server managed file

I am attempting to read specific lines of GIANT text files (> 150 MB) with hundreds of thousands of lines. The files are contained on an FTP site. I can successfully open the files using FTPwebrequest and streamreader but to get to a specific line using streamreader, you have to read every line before it. Obviously this takes a lot of time when you need to get to the millionth line.
A much faster way, I think, would be to use filestream and the filestream.position function. However, I'm not sure how to open a file as a filestream from FTP. I have tried:
Dim ftpaddress as string = "ftp://####@ftp.textfile.asc+"
Dim fileStream1 As New FileStream(ftpaddress, IO.FileMode.Open, IO.FileAccess.Read)
I'm making a type of download manager which downloads parts of a file using HTTPREQUEST.addrange. The parts download without a problem and currently I use 5 instances of the same class to download the parts simultaneously each one downloading a different section of the file. Now my problem is that I don't want to save each part as a file then merge them later, I want to use a singular filestream and append everything asynchronously. In the code below I attempted to use the seek method but it feels like it changes the seek for all of the other parts as well.

i searched a bit but i cant find something useful.i need to take my files to filestream (i can do this with file paths)and i wanna save this files to somewhere else on my program. Is it possible that with the using FileStream?
View 2 RepliesI am trying to read in a file and store the byte position of each line read so that I can write out to another file the records in any order that I want. I am doing more manipulation of the lines, hence why I need the line position from the original file, but for simplicity sake, I am just including code to display the problem I am encountering. When I read in the file, I am getting the correct file position, but when I write out the lines, every 1024 characters it is re-writing whatever current line it is on. I am assume there is some buffer that is coming into play that I am not familiar with,

I am looking to write the contents of a dictionary to XML. I have written the dictionary contents to a string as i have been told it is easier to write from a string to XML instead of from a dictionary. But im not sure if this is correct?

VB.NET application which allows user to split a file in smaller files. However the stand alone executable of the application,had a permission problem using filestream to read a file without an OutOfMemory exception, while selecting to split locatein certain directories like "C:".To solve the problem i checked My Project window and the "Security" tab, and i tried checking the checkbox: "Enable ClickOnce Security Setting" and selecting "fulltrust application". This added to my app.manifest these lines of code:

I am using BinaryFormatters (System.Runtime.Serialization.Formatters.Binary.BinaryFormatter) and FileStreams (System.IO.FileStream) to perform simple Open, Save, and Save As commands. I am using a separate FileStream and BinaryFormatter in each method.
My issue is that there is a delay for between four and ten or so seconds after performing any of those abilities before you can perform any other of them. Apparently the file is open in "another process", which (my guess) is the FileStream.Let's say I save and close a file in my app. I then go File > Open and select the same file and go to open it. I get that error returned.This isn't really an issue with the code, it's more me asking what the reasons are for why this is happening. What would be a way to work around this?
I have a filestream, and I want to save a file from that filestream? Like there are bytes in that file stream, and from those I want a "file.exe" to automatically appear on my desktop.
I'm using a code snippet, and I think this is the important part:
Dim fstr As New FileStream("file.exe", FileMode.OpenOrCreate, FileAccess.Write)
fstr.Write(validArg1, validArg2, validArg3)
fstr.Close()
Do I have to use a for loop? Or is there a function like this:
IO.File.WriteAllBytes(myPath, fstr.AllBytes)
Filestream URI format not supported?
View 3 RepliesI am trying to build a resource file for a website basically jamming all the images into a compressed file that is then unpacked on the output buffers to the client. my question is in vb2005 can a filestream be multi threaded if you know the size of the converted file, ala like a bit torrent and work on pieces of the filestream ( the individual files in this case) and add them to the resource filestream when they are done instead of one at a time?

fs.WriteByte(&HB3)

This works as expected and everything is fine until this point.Now i tried to solve this problem by code.Tried the following:fs.writebyte(&H(str))Str contains the actual hex value to write.
