Problem uploading files larger than 30K

Hi guys,
I am trying to upload a jpg file to a server but keep getting a web exception. Now the error occurs when i write the line httpwebrequest.getresponse and i've tested the status of the error and if displays a message when comparing the status to webexceptionstatus.timeout.
When i output the message in the exception it says:

An error message cannot be displayed because an optional resource assembly containing it cannot be found.

Now this only appears to happens on files larger than 30K and i was wondering whether anybody had come across this problem before or be able to help me with my problem.

If you need to see my code to upload then i will gladly supply it.

Thanks in advance for any help

You can use
My.Computer.Network.UploadFile()

Thanks for the quick reply but will that work in compact framework???
(Sorry i know i probably should've mentioned that before)

I think it will work in cf 2.0

Ok i'll try it out...but i just think that there might be something simple i can change with my code as it only happens when my files are larger than 30K.

Does anybody have any ideas????

Thanks. :thumb:

Put the conection timeout to 0

Ok i'll try that....but what will that do....will it just not wait for a response and try again next time??? If so then i am still going to run into my problem of not being able to upload anything larger than 30K.

Here is the code i am using to upload each file:

Code:

---

    Public Function UploadFileBinary(ByVal localFile As String, ByVal uploadUrl As String)
        Try
            ' Define the fact we don't want fully trusted certs
            ServicePointManager.CertificatePolicy = New MyCertificateValidation

            ' Create a request
            Dim req As HttpWebRequest = HttpWebRequest.Create(uploadUrl)


            ' Create a new CredentialCache object and fill it with the network
            ' credentials required to access the server.
            Dim credentials As NetworkCredential = New NetworkCredential("username", "password")
            Dim credentialCache As System.Net.CredentialCache = New CredentialCache
            credentialCache.Add(New System.Uri(uploadUrl), "Basic", credentials)
            req.Method = "PUT"
            req.Credentials = credentialCache
            req.AllowWriteStreamBuffering = True

            ' Retrieve request stream
            Dim reqStream As Stream = req.GetRequestStream()
            ' Open the local file
            Dim rdr As FileStream = New FileStream(localFile, FileMode.Open)
            ' Allocate byte buffer to hold file contents
            Dim inData() As Byte = New Byte(1024) {}
            ' loop through the local file reading each data block
            '  and writing to the request stream buffer
            Dim bytesRead As Integer = rdr.Read(inData, 0, inData.Length)
            While (bytesRead > 0)
                reqStream.Write(inData, 0, bytesRead)
                bytesRead = rdr.Read(inData, 0, inData.Length)
            End While
            rdr.Close()
            reqStream.Close()
            frmSchedule.controlInvoker.Invoke(New MethodCallInvoker(AddressOf frmSchedule.invokeWaitCursor), True)
            req.GetResponse()
            frmSchedule.controlInvoker.Invoke(New MethodCallInvoker(AddressOf frmSchedule.invokeWaitCursor), False)
            Return True
        Catch webEx As WebException
            If webEx.Status = WebExceptionStatus.ProtocolError Then
                Debug.WriteLine(TAB & "Web Exception caught in Upload.UploadFileBinary() - Authorisation Failed" & NEWLINE & TAB & webEx.Message.ToString)
                'ElseIf webEx.Status = WebExceptionStatus.Timeout Then
                '    Debug.WriteLine(TAB & "Web Exception caught in Upload.UploadFileBinary() --> Timeout." & NEWLINE & TAB & webEx.Message.ToString & NEWLINE & TAB & webEx.Response.ToString)
            ElseIf webEx.Status = WebExceptionStatus.Timeout Then
                Debug.WriteLine(TAB & "Web exception caught in Upload.UploadFileBinary() --> Timeout." & NEWLINE & TAB & webEx.Message.ToString.ToString)
            Else
                Debug.WriteLine(TAB & "Web Exception caught in Upload.UploadFileBinary() --> Other reason." & NEWLINE & TAB & webEx.Message.ToString & NEWLINE & TAB)
            End If
            frmSchedule.controlInvoker.Invoke(New MethodCallInvoker(AddressOf frmSchedule.invokeWaitCursor), False)
            Return False
        Catch ex As Exception
            Debug.WriteLine(TAB & "Exception caught in Upload.UploadFileBinary()." & NEWLINE & TAB & ex.Message.ToString)
            Return False
        End Try
    End Function
