[Quickfix-users] getHeader() problem with quickfix.1.5.0

[Christodoulou, C. D (london) <chr...@ml...>]

Hi

I have installed quickfix 1.5.0 on Windows using Visual Studio on XP
machine. I am running the .NET version (managed code) since I am using C# to
talk to the quickfix dll.

I am trying to get the MsgType from a NewOrderSingle message, however,
whenever I try to return the MsgType I get a compilation error:

-- Cannot implicitly convert type 'QuickFix.Message.Header' to
'QuickFix42.Header'


Code example:
// Create a FIX request
NewOrderSIngle newOrder = new NewOrderSingle();

Header header = newOrder.getHeader(); <== compile error
 
QuickFix.MsgType msgType = new QuickFix.MsgType();
QuickFix.StringField strType = Router.getField(msgType);



The getHeader() is declared as follows:

namespace QuickFix42
{
  public __gc class Header : public QuickFix::Message::Header
  {
    Header(QuickFix::Message* message) : QuickFix::Message::Header(message)
{}
    
    NET_FIELD_SET(BeginString);
    NET_FIELD_SET(BodyLength);
    NET_FIELD_SET(MsgType);

	...
  }

  ...

  Header* getHeader() { return
dynamic_cast<Header*>(QuickFix::Message::getHeader()); }

}

Therefore I am expecting it to return a QuickFix42 header, however it
actually thinks it's returning a QuickFix header which results in the above
compilation error.

If I use the QuickFix.Message.Header then the derived MsgType is not
available to me.

Has anyone got any ideas?

Also, I am a little confused as to why getHeader is returning a pointer.

Thanks
Chris
