How to get MainFrame window into activeX via another activeX

[maheshbeniwal]

Dear All,
I have developed two activeX controls, say AX and BX. BX has one method called SetFileName which views file on mainframe window if we pass mainframe window as a parent window during Create method call of BX. It wroks fine. For both ocx i am using wrapper class and create method to create controls. Now my problem is i want to use BX->SetFileName method via AX. I am creating my AX in Application usin create method and passing mainframe window. Then there is method of AX called GetRx(long lWnd). I am passing mainframe window's handle and converting to other end. I did DEBUG .. i am getting same window on both the ends but it does not display any thing.

any ideas ?
here is my code


-----------------------------------------------------
This is applications's view class
-------------------------------------------------------------------
void CKControllerView::OnMcb()
{
CRect rInsoWnd;
GetClientRect(&rInsoWnd);
long longParam = (long)AfxGetApp()->m_pMainWnd->m_hWnd ;
AllocMemFormcb(CMcbViewer);

/* mcb is instance of wrapper class of AX */
mcb->Create("mcbViewer",WS_CHILD|WS_VISIBLE, rInsoWnd, (CWnd*)this, 1113,
NULL, FALSE);

/* Method of AX , given below */
mcb->GetRx(longParam);

}


----------------------------------------------------------------
AX activeX control which calls SetFileName of BX which views the file
----------------------------------------------------------------------------
-----------------------
long CMcbViewerCtrl::GetRx(long lhWnd)
{
CRect rInsoWnd;
GetClientRect(&rInsoWnd);

CWnd* wnd = CWnd::FromHandle(HWND(lhWnd));

AllocMemForViewer(CRxhighx);

/* Creating BX */
m_pViewerWnd->Create("Rxhighx", WS_CHILD|WS_VISIBLE, rInsoWnd, wnd, 2222,
NULL, FALSE);

/* this method works fine becuase later i am calling GetAction and returning
correct value */
m_pViewerWnd->SetAction(1);

/* This method works fine too b/c i am getting correct value in str but it
does not display */

m_pViewerWnd->SetFileName("C:\\winnt\\winnt.bmp");

return 0;
}

are AX and BX in the same container ?

[maheshbeniwal]

Ax is a container of BX .. but BX does not have any window or dialog ..

My application is container of AX .. which ca. In Ax i call BX->Create method and pass mainframe window of application as a parent window of BX.

[maheshbeniwal]

I treid to create a dummy window in AX and passed that dummy window as parent of BX. It worked fine .. but my porblem is i want to display on mainframe. Can i do that ??

thanks and regards
