two dialogs to same class

Hi all,
Can we add two dialogs to the same class?
Consider two dialogs A and B of class clz.
now if i make a call as
clz obj;
obj.DoModal();
here which dialog is invoked.


Thank u.

This is somehow a strange feature. Maybe if you explain what you want to achieve, we can give you some advice.

I want to invoke dialog A or B depending upon my requirements.

But, they behave different?

If so, make 2 classes. Then, in the class which implements your special requirements, you invoke the right dialog:

Code:

---

if (bShowDialogA)
{
    CMyADlg dlgA;
    dlgA.DoModal();
}
else
{
    CMyBDlg dlgB;
    dlgB.DoModal();
}

A dialog Creation depends on the ID of the Dialog .and it's upto you which id you are going to provide to your dialog .and on the basis of IDD u can make a call to your apropriate dialog .

Thankyou

Of course we can "add" two dialogs to the same class.
We should make it clear that a "dialog" is a kind of resource.
And it's identified by its ID (always IDD_ heading).

We Create a dialog class inherits from CDialog,it doesn't mean that we
must attach a dialog ID to it.
for example:

class CMyDlg: public CDialog
{
CMyDlg(CWnd* pParentWnd = NULL); //Standard construction
CMyDlg(UINT nIDTemplate, CWnd* pParentWnd = NULL); //Not standard

virtual ~CMyDlg();
...
}

We can use this dialog class in this way:

CMyDlg *pMyDlg1;
CMyDlg *pMydlg2;

ok,now,if you want any of the two dialog to be a Mode dialog:

pMyDlg1 = new CMyDlg(IDD_DIALOG_ONE,pParentWnd);
pMyDlg2 = new CMyDlg(IDD_DIALOG_TWO,pParentWnd);
//Note: pParentWnd can be NULL

pMyDlg1->DoModal(); //Create and activate it!
pMyDlg2->DoModal();

If you want them to be Modeless,do in this way:

pMyDlg1 = new CMyDlg(pParentWnd);
pMyDlg2 = new CMyDlg(pParentWnd);
//Note: pParentWnd also can be NULL

pMyDlg1->Create(IDD_DIALOG_ONE,pParentWnd);
pMyDlg2->Create(IDD_DIALOG_TWO,pParentWnd);

pMyDlg1->ShowWindow(SW_SHOW);
pMyDlg2->ShowWindow(SW_SHOW);

In this way, many dialogs can share one class,isn't it great?

PS:the not standard construction is like this:

CMyDlg::CMyDlg(UINT nIDTemplate, CWnd* pParentWnd)
: CDialog(nIDTemplate, pParentWnd)
{
//{{AFX_DATA_INIT(CMyDlg)
// member initials here
//}}AFX_DATA_INIT
}


Over....haha
