First trial with XDE

Hello all,

I try to read STEP and IGES files via the new XDE package. But since this are my first steps with OCAF I got some problems. Here's the code:

CFileDialog dlg(TRUE,

NULL,

NULL,

OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,

"STEP Files (*.stp , *.step)|*.stp; *.step; |All Files (*.*)|*.*||",

NULL );

if (dlg.DoModal() == IDOK)

{

CWaitCursor aWaitCursor;

CString filename = dlg.GetPathName();

Standard_CString aFileName = (Standard_CString)(LPCTSTR)filename;

STEPCAFControl_Reader reader;

IFSelect_ReturnStatus readstat = reader.ReadFile(aFileName);

if ( !reader.Transfer ( myOcafDoc ) )

{

AfxMessageBox("Cannot read any relevant data from the STEP file");

}

else

{

myOcafDoc->CommitCommand();

myAISContext->UpdateCurrentViewer();

UpdateAllViews(NULL);

}

}

It reads the file but I don't get shapes in my 3D-View.

What am I doing wrong?
