My program is in need of a lot of cleanup and restructuring.
In another post I asked about leaving the MFC DocView framework and going to the WinProc & Message Loop way (what is that called for short?). Well at present I am thinking that I should clean up what I have in Doc View and perhaps later convert to non-MFC it that even makes sense. My Document class currently has almost nothing useful in it.
I think a place to start is the InitInstance() function (posted below).
In this part:
POSITION pos=pDocTemplate->GetFirstDocPosition();
CLCWDoc *pDoc=(CLCWDoc *)pDocTemplate->GetNextDoc(pos);
ASSERT_VALID(pDoc);
POSITION vpos=pDoc->GetFirstViewPosition();
CChildView *pCV=(CChildView *)pDoc->GetNextView(vpos);
This seem strange to me. I only have one doc and one view. I feel like I am going about it backwards with GetNextDoc() and GetNextView(). To try to use a silly analogy; it's like I have a book in my hand but I have to look up in it's index to find out what page the Title of the book is on. I'm tired of feeling embarrassed about my code. I either need correction or reassurance, or both. :)
Also, all the miscellaneous items are in no particular order. I would like to rearrange them into an order that may be more standard, structured or straightforward.
ALL suggestions welcome!
BOOL CLCWApp::InitInstance()
{
InitCommonControls();
if(!AfxOleInit())
return FALSE;
// Initialize the Toolbar dll. (Toolbar code by Nikolay Denisov.)
InitGuiLibDLL(); // NOTE: insert GuiLib.dll into the resource chain
SetRegistryKey(_T("Real Name Removed"));
// Register document templates
CSingleDocTemplate* pDocTemplate;
pDocTemplate = new CSingleDocTemplate(
IDR_MAINFRAME,
RUNTIME_CLASS(CLCWDoc),
RUNTIME_CLASS(CMainFrame),
RUNTIME_CLASS(CChildView));
AddDocTemplate(pDocTemplate);
// Parse command line for standard shell commands, DDE, file open
CCmdLineInfo cmdInfo;
ParseCommandLine(cmdInfo);
// Dispatch commands specified on the command line
// The window frame appears on the screen in here.
if (!ProcessShellCommand(cmdInfo))
{
AfxMessageBox("Failure processing Command Line");
return FALSE;
}
POSITION pos=pDocTemplate->GetFirstDocPosition();
CLCWDoc *pDoc=(CLCWDoc *)pDocTemplate->GetNextDoc(pos);
ASSERT_VALID(pDoc);
POSITION vpos=pDoc->GetFirstViewPosition();
CChildView *pCV=(CChildView *)pDoc->GetNextView(vpos);
if(!cmdInfo.m_Fn1.IsEmpty() && !cmdInfo.m_Fn2.IsEmpty())
{
pCV->OpenF1(cmdInfo.m_Fn1);
pCV->OpenF2(cmdInfo.m_Fn2);
pCV->DoCompare(); // Sends a paint message when complete
}
// enable file manager drag/drop and DDE Execute open
m_pMainWnd->DragAcceptFiles(TRUE);
m_pMainWnd->ShowWindow(SW_SHOWNORMAL);
m_pMainWnd->UpdateWindow(); // paints the window background
pCV->bDoSize=true; //Prevent a dozen useless size calculations
return TRUE;
}
Thanks
