You need a pointer to the document template you want to open a document for. In MFC these templates are stored in a CDocManager class object pointer which is part of your CWinApp object. You could do this:

CDocManager *pDocMan = AfxGetApp()->m_pDocManager;
POSITION pos ;

pos = pDocMan->GetFirstDocPosition();
while (pos)
{
CDocTemplate *pTemplate = pDocMan->GetNextTemplate(pos);
pTemplate->OpenDocumentFile(filename); // or NULL ofr an empty document
}

I may have some of the function names wrong here as its from memory.

Roger has one way of doing it...

We use CWinApp::OpenDocumentFile(LPCTSTR lpszFileName). Does the same thing, but automatically. Smile | :)

ClassWizard Not Working Properly

I have VC++ .NET and the class wizard is not working properly. I can't add Code Project code to the application I am working on because the "add member variable" feature is always grayed when I right-click an object in the resource editor. WHY DOES IT DO THAT?! I'M ABOUT READY TO RIP MY COMPUTER APART! Please Send Help! Is it a settings problem, or just Microsoft's way of slowly driving me insane?

Make sure you have already created a class for the resource you are trying to add member variables to by double clicking on the resource your editing or right clicking and choosing "add class."

Floating CControlbar Question ...

28-Nov-02 11:19

background : I need to be able to handle the close button of a miniframe window of a CControlBar; the only way ( that I Found ), is to hack it in the system with the undocumented : m_pFloatingFrameClass member of CFrameWnd :

// something like that with (pBar is a CCOntrolBar inherited class )
if ( pBar )
{
 if( !pBar->Create("wow", this, IDC_OBJECT_TOOLBAR) )
 {
  TRACE0("Failed to create object bar\n");
  return -1;       // fail to create
 }
 pBar->SetBarStyle( pBar->GetBarStyle() | CBRS_TOOLTIPS | CBRS_FLYBY |  CBRS_SIZE_DYNAMIC );
 pBar->EnableDocking( CBRS_ALIGN_LEFT | CBRS_ALIGN_RIGHT );
 EnableDocking(CBRS_ALIGN_ANY);

 // in the documentation of CSizingControlBar they write that it must be just after the EnableDocking call.
 m_pFloatingFrameClass = RUNTIME_CLASS(FloatingBarFrame);

 DockControlBar(pBar, AFX_IDW_DOCKBAR_RIGHT|AFX_IDW_DOCKBAR _LEFT);

 pBar->LoadState(s);
}

this works sometimes ( and in another case ) ?!?^!^?!^!%!@@$!@#$!%

Mad | :mad:

question I have, can LoadState of the CControlBar and the LoadBarState of the CFrameWnd break the m_pFloatingFrameClass ? I still don't full understand why it doesn't really work ...

Any ideas ( maybe the turkey will help ! ) ?

Thanks.

Max.

you can use GetNextDlgTabItem to find the next control in the tab order. so, override OnKeyDown, when you get a VK_RETURN, find the CWnd for the control that currently has focus, then use GetNextDlgTabItem to find the 'next' control.

The way to do this is to pop up a dialog that is not a regular shape. There are plenty of articles on the web for how to do that.

If i for example have this string: "192,168,135,97,51,156" is it possible to split that into 6 integers containing the values delimited by the comma?

strtok should do the thing ...
also, could do it by hand with CString ( and/or std::string )

strtok is the one, but be careful if you have "blank" tokens e.g. "1,2,3,,5".

strtok will say there are 4 values here rather than 5 (4 numbers and one blank token).

treeview node deletion question.

28-Nov-02 8:53

hi everyone,

how do you delete a node from a treeview control? i had a sdi, based on treeivew, and i bind double click to the node deletion command.. i tried double click on my program, but nothing happens. if i reload my program, the previously double clicked node is gone.. does treeview refreshes by itself after i ran DeleteItem() function? i've also tried running UpdateAllViews(NULL), but it causes my program to crash for some reason..

this is how i coded my OnDoubleclick()

void CmyView::OnDoubleclick(NMHDR *pNMHDR, LRESULT *pResult)
{
NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*) pNMHDR;
GetTreeCtrl().DeleteItem(pNMTreeView->itemNew.hItem);
UpdateAllViews(NULL); // this line causes my program to crash
*pResult = 0;
}

UpdateAllViews doesn't have anything to do with your tree control not updating, so you can remove that line.

It's possible the tree control doesn't expect you to delete the node you double-clicked on in the handler for the double click notification. You could try posting a user-defined message to your view in the double click handler, and then delete the item in the handler for the user-defined message.
