    copied!<p>I have some different methods that each import products from different sites. If I execute these sequentially the entire process takes a lot of time, particularly when 1 method is running on a site that is less responsive.</p> <p>I'd rather run them simultaneously.</p> <p>This is what I have so far with 1 example method:</p> <pre><code>Public Class feedParameters Private _productIdPrefix As String Private _publishersite As String Private _feedURL As String Public Property productIdPrefix() As String Get Return _productIdPrefix End Get Set(value As String) _productIdPrefix = value End Set End Property Public Property publishersite() As String Get Return _publishersite End Get Set(value As String) _publishersite = value End Set End Property Public Property feedURL() As String Get Return _feedURL End Get Set(value As String) _feedURL = value End Set End Property End Class Dim fpm As New feedParameters fpm.publishersite = "mypublisher.nl" fpm.feedURL = "http://www.domain.com/test.xml" fpm.productIdPrefix = "10" Protected Sub ImportProductsPublisherA(ByVal productIdPrefix As String, ByVal publishersite As String, ByVal feedURL As String) End Sub </code></pre> <p>I tried this:</p> <pre><code>System.Threading.ThreadPool.QueueUserWorkItem(New System.Threading.WaitCallback(AddressOf ImportProductsPublisherA()), fpm) </code></pre> <p>Then I get 3 errors that I have not specified arguments for the 3 parameters: productIdPrefix, publishersite and feedURL </p> <p>I also tried: </p> <pre><code>System.Threading.ThreadPool.QueueUserWorkItem(New System.Threading.WaitCallback(AddressOf ImportProductsPublisherA), fpm) </code></pre> <p>I get this error: Method 'Protected Sub ImportProductsPublisherA(productIdPrefix As String, publishersite As String, feedURL As String)' does not have a signature compatible with delegate 'Delegate Sub WaitCallback(state As Object)'. </p> <p>Any help is greatly appreciated!</p>
