once you call erase, the iterator becomes invalid.
erase will return an iterator to the next item.
so your loop looks something like this

for (it=stuff.begin();it!=stuff.end();/*DON'T INC IT HERE*/)
{
   bool bKeepThisOne=SomeCondition(it);
   if (bKeepThisOne)
      ++it;
   else
      it=stuff.erase(it);
}

I am trying to connect to an SQL server database using the OLE DB templates but am getting above error when linking. The code causing the error is:

hr = m_srcProduct.OpenWithServiceComponents(CLSID_SQLOLEDB, &initStd, 1);
//(m_srcProduct is a CDataSource object)

I have sqloledb.h included in stdafx.h, it has the declaration for CLSID_SQLOLEDB but it is declared extern which I think may be the problem....

//----------------------------------------------------------------------------
// Provider-specific Class Ids
#ifdef DBINITCONSTANTS
// Provider CLSID {0C7FF16C-38E3-11d0-97AB-00C04FC2AD98}
extern const GUID CLSID_SQLOLEDB ={0xc7ff16cL,0x38e3,0x11d0,{0x97,0xab,0x0,0xc0,0x4f,0xc2,0xad,0x98}};

how to fix?

Changing a view in an SDI.

I have an SDI application with multiple views available. Each view is derived from CFormView and is specified with a unique dialog ID.

My question is how do I change the view from one view to a user select one? I have options off of the menu bar that the user selects, this puts all the view changes inside my CMainFrm class. I don't want to destroy the original view that the application starts with, but after that all of the new views can be destroyed after they are used and moved to a new one.

Any help is appreciated.

I had to do this a couple of months ago and found the articles about document/view here at code project helpful. There was also several examples in the MSDN library about this subject.

Anatari,

Thanks for the help. I am having one problem though. When I goto create my new view using te Create method I get a compile error of "Create: cannot access protected member declared in class CFormView"

Here is what I am attempting per the article you suggested.

if(!m_pMyView) MyView is a class derived from CFormView
{
m_pMyView = new CMyView;

m_pMyView->Create(NULL, NULL, AFX_WS_DEFAULT_VIEW, CFrameWnd::rectDefault, AfxGetMainWnd(), AFX_IDW_PANE_FIRST+1, NULL);
}

I am doing this in the OnNewDocument of my Document class. Any ideas why I get this error? I have taken the constructor and destructors of my new Vew class and made them public and removed all the DECLARE_DYNCREATE and IMPLEMENT_DYNCREATE macros from the header and source files of the class.

You have to override the create method in the CFormView derived class you're trying to show

How do I open a new document in a MDI app without using CView::OnFileNew(). The app supports multiple doc's and I want to be able to open new one's from anywhere. I am sure it is simple. Thank you in advance.

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.

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.

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.

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).
