MFC: calling the Create function of a custom dialog object: rect, parentWnd, nID

I'm following an MFC tutorial that covers the implementation of a custom CListCtrl style control, that is actually a custom Wnd derived class.

I've bound a Custom dialog item to the class in this manner:
void CLustreView::DoDataExchange(CDataExchange* pDX)
{
CFormView::DoDataExchange(pDX);
DDX_Control(pDX, IDC_CUSTOM1, grid); // grid is an object I instantiated from the class
}

According to the tutorial, you create the object thusly:

CGridCtrl grid;
grid.Create(rect, pParentWnd, nID);

I suspect that I should call this Create function, having obtained a rect area through the GetClientRect() function, and having obtained the parent through the GetParent() function, while just passing IDC_CUSTOM1 as the third argument. I'm unsure of exactly how to do so. Please advise,

< DDX_Control(pDX, IDC_CUSTOM1, grid); // grid is an object I instantiated from the class>
not required - you are creating the control yourself.

CGridCtrl grid; - In header file, not local to a function

grid.Create(rect, pParentWnd, nID);
In the OnInitDialog.
rect is the recatngle you want (client co-ordinates), pParentWnd can be this (the dialog) and nID is the UNIQUE identifier.

CGridCtrl grid is in a header file (though that wasn't apparent from my post).

How can I obtain a rect object that has the same area as my variably sized IDC_CUSTOM dialog item?

by unique identifier, do you mean resource ID?

Thanks a lot,

This has the effect of making the dialog object fill the entire frame:
CRect rc;
GetClientRect(&rc);
grid.Create(rc, this, IDC_CUSTOM1);

All I need now is to figure out a way of getting a CRect object that has the co ordinates of my IDC_CUSTOM1 object,

Thanks again andy

So you mean that I should have an ID for each dialog item, like this, from resource.h?

#define IDC_RADIO1 1025
#define IDC_RADIO2 1026
#define IDC_COMBO5 1027
#define IDC_COMBO6 1028
#define IDC_PRODUCTSEARCHLIST 1030
#define IDC_COMBO1 1031
#define IDC_COMBO2 1034
#define IDC_CUSTOM1 1035

It would be best if the ID of the grid isn't the same as an ID used for another control. (in numbers of cases it may well not cause a problem if it was duplicated but best to get used to doing it right from the start)

Ok, Thank you.
