Polarion Web Service: C#.NET -> dll -> VBA = type mismatch!

Postby bt_roke » Thu Jun 24, 2010 8:13 am

Hello all

What we need to to is, to access the Polarion Web Service from a MS Access VBA application.

We where able to

  • generate C# .NET code from the XML interface description (wsdl) in Visual Studio C# 2008 Express Edition
  • generate a dll in Visual Studio C# 2008 Express Edition
  • make the dll a COM component and register it to the Windows system (PolarionWS)
  • include the PolarionWS COM component in MS Word
  • connect to the Polarion server
  • log into the Polarion server
  • Request the getOneDayLength from the Polarion server
    (Dim oneDayLength As Long
    oneDayLength = trackerService.getOneDayLength

What now causes a "Type mismatch" error 13 is

  • all call to methods that return a array of class objects
    (which is the majority of the methods e.g.
    Dim timePoints() As PolarionWS.TimePoint
    timePoints = trackerService.getTimepoints("myProject")

Not assigning the trackerService.getTimepoints("myProject") to the timePoints variable does not cause the error. Checking with WireShark shows, that the data gets transmitted between the apps.

In C# .NET the methode looks as follows:

/// <remarks/>
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("", RequestNamespace="http://ws.polarion.com/TrackerWebService-impl", ResponseNamespace="http://ws.polarion.com/TrackerWebService-impl", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
[return: System.Xml.Serialization.XmlElementAttribute("getTimepointsReturn")]
public TimePoint[] getTimepoints(string projectId) {
object[] results = this.Invoke("getTimepoints", new object[] {
return ((TimePoint[])(results[0]));

Has anyone experience with complex data types, COM components between .NET and VBA and can help out?
