CFromView
-
Hi, I created the CFromView dynamically, Form is having CListCtrl where should set the style for CListCtrl? the below code is giving error as m_ListDriveis is NULL .
bool CRecoverDriveDlg::CreateView(UINT Style, CRect rect,CWnd *Parent)
{
Create(NULL,NULL,Style,rect,Parent,0x10,NULL);m\_ListDrive.SetExtendedStyle(LVS\_EX\_FULLROWSELECT);//error return 1;}

What is
m_ListDrivesupposed to be and where is it initialised?Unrequited desire is character building. OriginalGriff I'm sitting here giving you a standing ovation - Len Goodman

I'm guessing what you mean is
m_ListDrivis.m_hwndis null. The variable somehow needs to be attached to the dialog control. This can be done with Dynamic Data eXchange (DDX) or the SubclassDlgItem[^] function, which must be called beforem_ListDrive.SetExtendedStyle(LVS_EX_FULLROWSELECT);. You could also make it into a pointer in the class definition, and then usem_ListDrive = (CListCtrl *)GetDlgItem(IDC_MY_LIST); //CListCtrl is whatever control type it is, IDC_MY_LIST is the control ID set in the properties window in the dialog editor.
m_ListDrive->SetExtendedStyle(LVS_EX_FULLROWSELECT); -

Why shouldn't it be
NULL? I mean, you didn't show us the code initializing it.If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.
This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong. -- Iain Clarke

m_ListDrive->SetExtendedStyle(LVS_EX_FULLROWSELECT);Where did you get all this about a dialog? The OP's question is about creating a window.

I have not used MFC for about a year now, so my memory could be a bit flaky, but: "These controls are laid out based on a dialog-template resource." - CFormView Class[^]. The form view is a pretty way of embedding a dialog into a MFC view. All of the controls on it have a dialog ID associated with them.

That may well be true but it does not seem to be the way OP is implementing it. I'm ready to stand corrected, however.

I could be completely wrong on this, but to me, it appears that he has defined a variable, something like
CListCtrl m_ListDrivein the CRecoverDriveDlg class. He is expecting this variable to automatically attach to some list control he has in the dialog template (I dont see a call tom_ListDrive.Create()). My suggestion was to manually attachm_ListDriveto this control somehow. It is possible that he has calledm_ListDrive.Create()elsewhere in his code and simply hasn't shown it and hence I am completely wrong. Since the original issue is m_ListDrive is NULL, then this call has failed, and that code would be relevant to helping him find a solution. -

We will see; or not!
