You can use CListCtrl member function GetView() to retrieve the view type.
If you are not using MFC you can pass LVM_GETVIEW message. check this link for details.
LVM_GETVIEW[^]

By calling GetWindowLong(hWnd, GWL_STYLE).

Where should I delete Dlg
If I delete in the MainFrame::~MainFrame(), it is giving following error

Unhandled exception at 0x006d7074 in ang.exe:0xC0000005
Access violation reading location 0xcdcdcdcd

LRESULT MainFrm::OnStart(WPARAM wParam, LPARAM lParam)
{
CString strPrgDlgTitle;
THREADSTRUCT_MF *_param = new THREADSTRUCT_MF;
_param->_this = this;
Dlg= new CDlg( this ,iMaxVal,iVal,str);
AfxBeginThread (StartProgThread, _param);
}

UINT MainFrm::StartProgThread (LPVOID param)
{
THREADSTRUCT_MF* ts = (THREADSTRUCT_MF*)param;
ts->_this->Dlg->DoModal();
return 1;
}

i'd delete it in the MainFrm destructor

and, i'd initialize Dlg to NULL in the constructor, and i'd make sure i checked that Dlg wasn't NULL before i tried doing anything with it anywhere else.

Have you used the debugger to step through the code to find the offending statement(s)?

It's not a good idea for a secondary thread to operate directly on a UI component owned by another thread. What you have looks as though it would block the primary thread.

I've a SDI project where View class is derived from
CFormView.
I need to change the form of the View on the fly in
order to show a different form for each application
status.
Is it possible to do that ? How ?

Thanks a lot !
