Hi and thanks in advance for your time reading this.

I've got a problem debugging my solution in VS2010. To be more specific, here's the setup:

  • everything is coded for Windows 7, 64bit
  • the 3rd party EXE (c++) exposes its api over c#
  • my plugin (c#) calls into a mixed mode dll
  • mixed mode dll calls native c++
  • native c++ dll calls a lot of production code already written for other programs (also native c++)
  • native c++ dll also calls another mixed mode dll which then calls a c# dll
  • everything written and compiled in VS2010

Here's the odd thing:

  • when I debug my managed code everything works fine; no exceptions
  • when I debug my native code I get random exceptions (0xe0434352) just when c++ calls into the mixed mode dll (which really just is an interface for the code in the c# dll)
  • when the exception window (first chance) pops up I hit skip/continue but no further debugging is possible; program execution results are the same though
  • the problem disappears if I comment out the call to the mixed mode code

EDIT:

Posting production code is a bit sensitive. The Exception is just the generic one I mentioned above. The exception window literally says:

  • An Exception (first chance) occurred at in Revit.exe: 0xe0434352: 0xe0434352.
  • It's Revit MEP 2013

  • maybe some sample code:

    c++:
dostuff()
{
    //it = std::list::iterator
    std::string = this->MixedMode->GetElementPropertyValue(Sel, it->Name, it->Api);
}

mixed mode:

std::string RevitBridge::GetElementPropertyValue(int Sel, const std::string &Name, const std::string &ApiName)
{
    String^ sName = gcnew String(Name.c_str());
    String^ sApiName = gcnew String(ApiName.c_str());
    String^ s = RevitUtils::GetElementPropertyValue(Sel, sName, sApiName);
    return std::string(msclr::interop::marshal_as<std::string>(s));
}

c#:

public String GetElementPropertyValue(int Sel, String Name, String ApiName)
{
    if (Sel < 0)
    {
        return "";
    }

    if (Name.Equals("_ElementID_"))
    {
        return this.GetElementID(Sel);
    }

    BuiltInParameter bip = BuiltInParameter.INVALID;
    try
    {
        bip = (BuiltInParameter)Enum.Parse(typeof(BuiltInParameter), ApiName);
    }
    catch (Exception) {}

    if (ApiName.Equals("INVALID") || BuiltInParameter.INVALID == bip)
    {
        return this.GetElemParamValueAsString_ByName(iters[Sel].Current, Name);
    }

    return this.GetElemParamValueAsString(iters[Sel].Current, bip);
}

I'd be glad for any kind of advice pointing me in the right direction.

Thanks, Kornel
