I am using the .NET 3.6.0 version where they provided the DLLS
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.
