Hi Everybody,
I am trying to upload a new file to a Web Server over a VB.NET App. I am using httpWebResponse and httpWebRequest to do so with a a PUT method. The server returns always a 501 Not Implemented Error. The code works fine on all XP Maschines but not on our Windows 2000 Server. I did have URL Scan installed on the server but killed it because I thought that was the cause of my problems but with no success.
Here is the code:
Dim Response As String = Nothing, FileSize As Double = 0
Try
UploadFile = False
If SourceLocation.ToString.Trim <> "" And DestinationLocation.ToString.Trim <> "" Then
'To set Upload settings
Dim UploadRequest As System.Net.HttpWebRequest = CType(System.Net.WebRequest.Create(New Uri(DestinationLocation.ToString.Trim)), System.Net.HttpWebRequest)
UploadRequest.Credentials = Credential
UploadRequest.Timeout = 60000000
UploadRequest.Method = "PUT"
UploadRequest.ServicePoint.Expect100Continue = False
UploadRequest.ContentLength = New System.IO.FileInfo(SourceLocation.ToString.Trim).Length
FileSize = UploadRequest.ContentLength.ToString.Trim
'To set Upload Stream settings
Dim SourceStream As New System.IO.FileStream(SourceLocation.ToString.Trim, System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.ReadWrite)
Dim RequestStream As System.IO.Stream = UploadRequest.GetRequestStream()
Dim Buffer(4095) As Byte
Dim Position As Integer = 0, ivlLoop As Integer = 0, CurLocation As Integer = 0
Position = SourceStream.Read(Buffer, 0, Buffer.Length)
While Position <> 0
RequestStream.Write(Buffer, 0, Position)
Position = SourceStream.Read(Buffer, 0, Buffer.Length)
CurLocation += Position
End While
'To upload Stream on Remote system
Dim WebResponse As System.Net.HttpWebResponse = CType(UploadRequest.GetResponse(), System.Net.HttpWebResponse)
Dim ResponseReader As New System.IO.StreamReader(WebResponse.GetResponseStream())
Response = ResponseReader.ReadToEnd()
UploadFile = True
RequestStream.Close()
UploadRequest = Nothing
SourceStream = Nothing
RequestStream = Nothing
WebResponse = Nothing
ResponseReader = Nothing
ElseIf SourceLocation.ToString.Trim = "" Then
Call MsgBox("Source Location is missing")
ElseIf DestinationLocation.ToString.Trim = "" Then
Call MsgBox("Destination Location is missing")
End If
Catch ex As Exception
Call MsgBox(ex.ToString)
End Try
Thank you in advance,
/Peace2u my friends

Basically, 501 means that the server doesn't support the PUT configuration you gave it. You might want to try reducing that 60000000 millisecond timeout to something like 30000. You might also want to try sending a smaller file, to see where that limit is. Some of these things you can change on the server to support higher limits, but I have no idea where. You might want to ask in the ASP.NET forum for that.

So what's wrong with translating the VB6 code? It's not going to be that different...

Hi I am totally a new commer in VB or VB .

Well It would be good to get a better answer than this. Its a kind of scope problem and it seems naming a class myClass is not liked and similar conflict naming a variable name, they are keywords.
So I changed it a little bit
Public Class Form1
Inherits System.Windows.Forms.Form
Dim t1 As TextBox
Dim t2 As TextBox
Private name1 As String
Private gpa As Double
Public Function assignvalue()
name1 = InputBox("Enter the name of students")
gpa = InputBox("Enter the GPA")
showvalue()
End Function
Public Function showvalue()
TextBox1.Text() = name1
t1.Text() = gpa
End Function
Public Class displayme
Public Shared Function show()
Dim s1 As New Form1
s1.assignvalue()
s1.showvalue()
s1.Show()
Dim t1 = New TextBox
Dim t2 = New TextBox
s1.Controls.AddRange(New Control() {t1, t2})
t1.Location = New Point(20, 50)
t2.Location = New Point(20, 100)
End Function
End Class
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
displayme.show()
End Sub
End Class

Thxx Sir, but it isnt working eithr  it is giving hell lot of errors

Sorry,
I think i made it worse. I will look at it, im just learning so it is interesting. Especially the scope part of it. Maybe try separating the classes a bit more, instead of having one inside another. But I am sure we will sort this out.
But it works if you keep your class outside the other class. I don't think nested classes are going to work!
Public Class Form1
Inherits System.Windows.Forms.Form
+windows Generated Code-----------
----------------------------------
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim f As New aClass
Label1.Text = f.myfunction
Label1.Text = f.showName
End Sub
End Class
Public Class aClass
Private strName As String
Private gpa As Double
Public Function myfunction()
strName = InputBox("Enter the name of students")
End Function
Public Function showName()
Return strName
End Function
End Class

How do you go about making your class accessible to other projects ?
Like say you have a custom messagebox ?

str="INSERT INTO tblHistoryLog(UserId,UserAction,TableName,ActionDate,TrDoneOn) VALUES('" + CheckValues.strUserId + "','NEW RECORD','USER TABLE','" + DateTime.Now + "','" + cmbTAUserId.Text + "')";
where ActionDate datatype if datetime.
i had inserted record in the table and inserted properly.
the query that uses the comparison
"SELECT * FROM tblHistoryLog WHERE (ActionDate BETWEEN #"+ dtpTo.Value +"# AND #"+ dtpFrom.Value +"#)"
but it gives the no result
i had tried to use this but it does not compile so i had to use above
"+ #dtpTo.Value# +" AND "+ #dtpFrom.Value# +"

What database are you using?
What is the data type of the field in the database?
---
b { font-weight: normal; }

datatype is datetime and i m using sql server2000
Tasleem Arif

Then you shouldn't use # arounds the date values. That is use with MS Access.
---
b { font-weight: normal; }
|
|
|
|

I assume that you are using either ASP.NET or windows forms as client. Try following:
"ActionDate BETWEEN" & " '" & Convert.ToDateTime(dtpFrom.Value).ToLongDateString & "' AND " & " '" & Convert.ToDateTime(dtpTo.Text).ToLongDateString & "'"
I also notice in your code, you are going from To...From! usually it is From...To right?
Hope this helps.

Hi everybody,
I use the following code to download a file from the Inet:
<br />
Private myClient As WebClient<br />
<br />
Private sub Load_It<br />
<br />
MyClient = New WebClient()<br />
MyClient.DownloadFile(myURIStr, fileName)<br />
<br />
End sub
This takes about 30 to 35 secs to fail if it cannot stablish a connection. Since I wanted to be able to Cancel the download at will, I tried calling this method from a running thread; but after this, I get an inmediate connection error when I try to download the file again; which does not happend if a wait for it to fail when using it outside the thread.
Any helpful ideas? 
thanks.
The same lost guy

Kindly reply me. It is urgent.
Thank You
