I'm running an FTP Server using Golder FTP Server, which is freeware. I think it's setup correctly because connecting to the FTP Server using the exact same string as above using Windows Explorer works great.
Alright here's my situation: I have a form. This is a very small form that can be moved with the mouse (formborderstyle=none). The transparencyKey is 0,0,1. The form back color is 0,0,1. There is a label on the form. I drag files to this label(its backcolor is black[0,0,0]). What I want is for the filesize to be checked. I already have the uploading to ftpcode, I just want to know if the file is above my limit I set. (250mb per file)

View 12 RepliesI just converted the following code from c# to vb.net. It is functional and works correctly with my company's firmware/devices. My next challenge. Previous serialport code used much more readable structs which where then converted (after building a packet) into byte() automatically as part of the serialport encoding. (this is my understanding)How could I
1. morph byte arrays 'ToSocket' and 'ToMTP' below into structs and
2. convert into byte array for Socket.BeginSend(byte(),.....) to stream out to remote devices?

Is it possible in VB to truncate a larger data type ( an int with a value greater than 255) to a smaller one, say a Byte (which only goes up to 255) in a way such that the 8LSBs of the integer are copied to the newly created byte. I have tried this using CType with the following code, however it does not work.
Dim TestByte As Byte = CType(Test, Byte)
Where the variable "Test" is an integer with a value of 419. This code always results in the Overflow exception.

I am writing a VB.Net app that has need to send a file to web script.
1. Dim uriString As New System.Uri("[URL]"+addNew_title.Text+"&price="+addNew_price.Text)
2. Dim myWebClient As New System.Net.WebClient()
3. Dim responseArray As Byte() = myWebClient.UploadFileAsync(uriString, OpenFileDialog1.FileName)
4. Dim response As String = System.Text.Encoding.ASCII.GetString(responseArray)
There is a problem with URI that I give, it says "Expression does not produce a value" on line 3. where "uriString" used. When I used myWebClient.UploadFile(String,String) it freeze on sending, so I found out, that to continue code execution I have to use "UploadFileAsync", but it does not provide [String,String], but it requires [Uri,String].
Just for the record, I will put a screenshot of code: [URL]
What do I have to change, so code is valid, or if there is another way to upload this file?

View 3 RepliesI've come across a problem with my program; I'm using MS Visual Studio 2010 with a VB.net application. I'm uploading a log file with .log ext to my server after my program is done running. I have noticed a lot of systems fail to upload the log file because of the firewall settings of their modem. I was wondering if anyone would know a workaround to uploading this file maybe on port 80. Here is the code I use to upload the file.
My.Computer.Network.UploadFile( _
"C:log.log, _
"ftp://www.myftpserver/logs/log.log, "loguser", "password")
Like I said this works fine if the Modem firewall in on low, but fails everytime if modem firewall is in the default setting. I believe it's using port 21 right now to upload.
