Hello

First of all please let me say sorry if this is in the wrong forum and please relocate it if neccessary.

Ok so I have a small vb.net application that runs on a timers and does a xmlhttp.send() when the timer ticks

On my developement machine, Windows 7 64bit in debug and release it works fine and I get my expectedreturned_value however I deploy this by one click and when the timer ticks on the Live server, Windows server 2012 64bit i get the excelption error "the parameter is incorrect"

Here is my code snippet

            Try
                Dim strPostData As String
                Dim objRequest As Object

                strPostData = xml

                'objRequest = New MSXML2.XMLHTTP
                objRequest = CreateObject("MSXML2.XMLHTTP.3.0")
                With objRequest
                    .Open("POST", url, False)
                    .setRequestHeader("Content-Type", "application/x-www-form-urlencoded")
                    .send(strPostData)
                    returned_value = .responseText
                End With

            Catch ex As Exception
                MsgBox("Error in Try Send " & RN & vbCrLf & "Error Message = " & ex.Message & vbCrLf & "Return Value = " & returned_value)
                Exit Sub
            End Try

I have also tired

objRequest = CreateObject("MSXML2.ServerXMLHTTP")

objRequest = CreateObject("MSXML2.XMLHTTP.3.0")

I am at a loss, any help would be great

thanks

Alan

The next thing I would do is make from the parameters instead of variables fixed values.

Success

Hi Checkprint,

Using MSXML with .NET is not recommended, please refer to here for more information: http://support.microsoft.com/kb/815112

For your requirement, it will work well by using WebRequest instead of xmlhttp, please see this artile about how to send Data Using the WebRequest Class:

I would first check if the used Net frameworks are the same

Thanks for the advice, I thought it might be something to do witht the framework so I changed ti from 2.0 to 3.5 still no joy

My development machine is 2.0.5727.5420

Live Machine is 2.0.5727.4927

Surely there is not alot of difference in these minor release?

Any other thoughts?
