Question

the request to send data to the computer running IIS has failed. for more information see HRESULT.

Asked by: LawCentral

Hello Everyone,

I am using VS2k3 on WInXP running IIS 5.1. I am trying to use RemoteDataAccess to pull data from SQL Server 2000 onto HP ipaq running SQL Server CE 2.0 and pocket PC 2002. The Pull method is giving me following error:

the request to send data to the computer running IIS has failed. for more information see HRESULT.

The code for the PULL is:

Private Sub btnPull_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPull.Click
        Dim cn As SqlCeConnection
        Dim rda As SqlCeRemoteDataAccess
        Dim sqlEngine As SqlCeEngine

        Try
            btnPull.Enabled = False

            'Create the database if it does not exist
            If (Not (File.Exists("\My Documents\IntelligenceData.sdf"))) Then
                sqlEngine = New SqlCeEngine
                sqlEngine.LocalConnectionString = "Data Source=\My Documents\IntelligenceData.sdf; Password=smarthouse; Encrypt Database=True"
                sqlEngine.CreateDatabase()
                sqlEngine.Dispose()
            Else
                'Open the connection to the database
                cn = New SqlCeConnection("Data Source=\My Documents\IntelligenceData.sdf; Password=smarthouse")
                cn.Open()

                Dim cmd As SqlCeCommand = cn.CreateCommand()

                'Drop the FieldMemos table
                cmd.CommandText = "DROP TABLE FieldMemos"
                cmd.ExecuteNonQuery()

                'close the connection
                If cn.State <> ConnectionState.Connecting Then
                    cn.Close()
                End If
            End If

            'Instantiate the RDA object
            rda = New SqlCeRemoteDataAccess

            'Create the connection string for connecting to
            'the SQL server
            Dim remoteConnectionString As String = "Provider=SQLOLEDB; " & _
                                                    "Data Source= Hemal_Laptop; " & _
                                                    "Initial Catalog=IntelligenceData; " & _
                                                    "User Id=sa; " & _
                                                    "Password=smarthouse"

            rda.InternetLogin = "Administrator"
            rda.InternetPassword = "password"
            rda.InternetUrl = "https://hemal_laptop/fieldagentrda/sscesa20.dll"
            rda.LocalConnectionString = "Data Source=\My Documents\IntelligenceData.sdf; SSCE:Database Password=smarthouse"

            rda.Pull("FieldMemos", "Select * From FieldMemos", remoteConnectionString, RdaTrackOption.TrackingOnWithIndexes, "FieldMemosErrorTable")

        Catch sqlEx As SqlCeException
            Dim sqlError As SqlCeError
            For Each sqlError In sqlEx.Errors
                MessageBox.Show(sqlError.Message)
            Next
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        Finally
            rda.Dispose()
            btnPull.Enabled = True

        End Try
    End Sub

If anyone knows the cause of this error please let me know ASAP. I have checked a lot of other posts on a lot of websites but havent arrived at any solution yet.

Thanks,

Hemal Modi

For the InternetUrl property of the SqlCeRemoteDataAccess, you need to use either the name of the computer on which the IIS is installed or the IP Address of that computer. So, the following methods of resource retreival are not effective in this regard:

    1. rda.InternetUrl = "https://localhost/fieldagentrda/sscesa20.dll"
    2. rda.InternetUrl = "https://127.0.0.1/fieldagentrda/sscesa20.dll"

However, in your example, I see the use of a computer name instead. You may only use computer names where the computer and the Pocket PC emulator or the actual Pocket PC device lie in the same domain.

    rda.InternetUrl = "https://hemal_laptop/fieldagentrda/sscesa20.dll"

This might not work if the computer is not on the same domain as is the device. To get around, this it might be feasible enough to give the IP Address of the computer where the IIS is installed. Try giving the IP Address of that particular computer. I tried this:

    rda.InternetUrl = "https://192.168.1.10/fieldagentrda/sscesa20.dll"   (You may provide your own here)

.. and it worked.
