I have an MFC SDI application with split windows and tabs. See Dan Clark's design: "Drag & Drop & Background Image Tree Control". I have three panes based on CView that display internal information. Two panes are CFormView based to display lots of buttons, trees and lists. It's an instrument panel. The core code includes a compiler/interpreter for a proprietary language (like java) called HTL. The problem: I also have two panes that are CRichEditView based. These are for the user to edit the HTL source code. The two views are already open in two panes. BUT, this is SDI, they don't have CDocuments, yet. How do I set up a doc/view architecture in InitInstance so that OnFileOpen() will add a doc and stick the file into one or the other view? Can I use CMultiDocTemplate in SDI? I don't want to create child windows like MDI does since I already have the window/pane set up. Right now it fails to find a view and then the frame calls OnInitialUpdate on everything and crashes when something gets called second time. So Hum

see the following MFC stuff: // Parse command line for standard shell commands, DDE, file open CCommandLineInfo cmdInfo; ParseCommandLine(cmdInfo); After the call to ParseCommandLine() everything will be placed in to cmdInfo. So Hum
