While the project file links the various source documents into a single project, the document-to-document and net connective relationships are defined by information in the documents themselves. A multi-sheet design project is arranged as a hierarchical structure of logical blocks, where each block can be either a schematic sheet or a HDL file (VHDL or Verilog). At the head of this structure is a single master schematic sheet, more commonly referred to as the project's top sheet.

What it doesn't have is support for MTLW (ok, so MS probably has a different acronym for it, but what I mean is Multiple Top Level Windows). This is the model popularized by those web browsers we all know and love, Netscape Navigator and Internet Explorer. ProblemThe main problem with MTLW and MFC is the main window (aka
SolutionSo what we need is a way to keep Two classes will help you do this:
Derive from these classes and wire up the message maps properly, and that's it. You're app now supports MTLW. Of course you need to have ways of creating new TLWs and probably you want to have a command to close all the windows and shut down your app, so the demo project includes those functions. First, a handler for the "New Window" menu item creates new TLWs. void CMultiTopSample::OnFileNewwindow() { CMainFrame* pFrame = new CMainFrame; pFrame->LoadFrame(IDR_MAINFRAME, Second, unless you want your users to have to close each window individually, you may want to have an "Exit" menu item which does the following: void CMultiTopSample::OnAppExit() { CloseAllFrames() ; } Is this easy, or what! How it works (briefly), and a BONUS member function:
list< CTopLevelFrame* > m_listMainFrames ; ... and a few functions for manipulating them: void AddFrame( CTopLevelFrame* pFrame ) ; void KillFrame( CTopLevelFrame* pFrame ) ; void ReplaceMainFrame( CTopLevelFrame* pFrame ) ; Plus a special bonus function. I use this to do print preview in YATLW and disable all the regular TLWs while I do so. void EnableFrames( BOOL bEnable );
