Saving Uploaded Picture Filepath To Sql Database

I am trying to save an uploaded picture filepath to a sql database record.  The record that the filepath will be saved to will be the record determined by the logged in userid.  I get an error stating Object not set to an instance of an object.  This is my code for when the upload button is hitProtected Sub uploadbutton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles uploadbutton.Click

If UploadTest.HasFile = False Then

' No file uploaded!

UploadDetails.Text = "Please first select a file to upload..."

Else

' Display the uploaded file's detailsUploadDetails.Text = String.Format( _

"Uploaded file: {0}<br />" & _"File size (in bytes): {1:N0}<br />" & _"Content-type: {2}", _

UploadTest.FileName, _

UploadTest.FileBytes.Length, _

UploadTest.PostedFile.ContentType)

' Save the fileDim filePath As String =  Server.MapPath("~/ProfilePictures/" & UploadTest.FileName)

UploadTest.SaveAs(filePath)Dim datasources1 As New SqlDataSourcedatasources1.ConnectionString = ConfigurationManager.ConnectionStrings("aspnetdb_connection").ToString()

datasources1.UpdateCommandType = SqlDataSourceCommandType.Text

Dim myUserID As String = Membership.GetUser().ProviderUserKey.ToStringdatasources1.UpdateParameters("userid").DefaultValue = myUserID


datasources1.UpdateCommand = "UPDATE into profile_details (pic) VALUES (@filepath) WHERE ([UserId] = @UserId)"

End If

End Sub

 

Any ideas on what i need to do to fix this?
