I found the problem. It was a third party library which caused it.
I've got a new version of that library and now the problem is fixed.

I am having windows media player as activex control
in my application. I am trying to use create method
for same but I am not able to use. Some where I am missing something.
CWMPPlayer4 m_lplayer;

void CApl2IEDlg::OnButton1()
{
RECT lprect;
lprect.bottom = 0;
lprect.left = 0;
lprect.right = 100;
lprect.top = 100;
RegisterWindow();
CWMPPlayer4 cwmp;
cwmp.Create(m_lplayer,mediaclass,0,lprect,(CWnd*)m_hWnd,0,NULL);

}

LRESULT FAR PASCAL WndProc(HWND hWnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
return (DefWindowProc(hWnd, Message, wParam, lParam));
}

void CApl2IEDlg::RegisterWindow()
{

mediaclass = "mediaclass";
WNDCLASS wndclass;
wndclass.style = CS_DBLCLKS | CS_HREDRAW | CS_VREDRAW;
wndclass.lpfnWndProc = WndProc;
wndclass.cbClsExtra = 0;
wndclass.cbWndExtra = 0;
wndclass.hInstance = AfxGetInstanceHandle();
wndclass.hIcon = LoadIcon(NULL,_T(""));
wndclass.hCursor = LoadCursor(NULL,IDC_ARROW);
wndclass.lpszMenuName = NULL;
wndclass.lpszClassName = mediaclass;

}

It looks like you might be using the wrong Create() for an activex control.

Make sure you're calling a Create() method from the wrapper class for the control.

To create the wrapper class (if you haven't already), you can use Project Menu/Add Class/MFC/
MFC Class from ActiveX Control.

I am using create method which is there in .cpp file which gets loaded once we insert control from registered controls. We can use other methods, Cant we use create?
Anyway I will try your suggestion tomorrow. But every time I try to create window for control this problem comes. I am really fed up of ActiveX controls but I have to use.

Hmm - I don't know what version of Visual Studio you're using, but I get two Create methods in
a wrapper class on Visual C++ 2003:

virtual BOOL Create(LPCTSTR lpszClassName, LPCTSTR lpszWindowName, DWORD dwStyle,
                                                const RECT& rect, CWnd* pParentWnd, UINT nID, 
                                                CCreateContext* pContext = NULL);

BOOL Create(LPCTSTR lpszWindowName, DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, 
                                                UINT nID, CFile* pPersist = NULL, BOOL bStorage = FALSE,
                                                BSTR bstrLicKey = NULL);

Neither of these match the parameters you are passing to Create().

Also...

The title of your post is "How to change place of activex control at run time".

Are you just wanting to change the position/size of the control or create the control at runtime?

I am using version of VC++ version 6.0. I dont understand your concept of wrapper class. The classes gets automatically created once you place activex control.
So I feel version in not required. The defination of create() which I have written is one which comes in Active X controls self generated classes.
Any way I done one mistake I dont need to create
control at runtime. I just need to change place at runtime so that I can save my text display. I got my own answer I have to get window then rect and change place. My current problem is diverted,but still these create remains problem.

In a dialog, you can add a control variable to the class just like any other control:

// Add the member to the class declaration
CWMPPlayer4 m_MediaPlayer;
...
// Add this line to DoDataExchange() (where IDC_PLAYER is the ID of the control resource)
DDX_Control(pDX, IDC_PLAYER, m_MediaPlayer);

Then any time after the control is created (after the base class OnInitDialog() has been called)
you can access it like any other window (CWMPPlayer4 is a CWnd-derived class)...

m_MediaPlayer.GetWindowRect(...)
m_MediaPlayer.MoveWindow(...)
etc.

Back Button : ID_WIZBACK
Next Button : ID_WIZNEXT
Finish Button : ID_WIZFINISH
then you can use GetDlgItem() to do whatever you want. I hope this helps

I have got three keys "TestKey", "dontknowkeyname", and "MyRequiredKey", can i know contents about "MyRequiredKey" even if i don't know about the key "dontknowkeyname".

I have got Registry Key Function, so that i can access "TestKey", can i access intermediate "dontknowkeyname" and then "MyRequiredKey".

In the sample code I put there, you can add the OnDragEnter()/OnDragLeave() overrides if you need
to respond to those as well.

How to detect which object called the message

Hi everyone,
I am using VC++ 6. I have a 3 listcontrols which display different data. I have customized the list control for the look and feel by creating a class "CCustomListCtrl" .I have created 3 instances of "CCustomListCtrl" in CMainFrame. class which I am using notification message "NM_CLICK" to detect the click on the list. Now i want to identify which of the user has clicked.

There is an NMHDR structure that's given as parameter to the function. It contains a variable called hwndFrom which denotes the control from which the notification came. You can use this handle.

Instead of handling the message in the CCustomListCtrl, handle that message in the CMainFrame itself. NM_CLICK is actually a notification. So handle the WM_NOTIFY message in the CMainFrame and check whether the code is NM_CLICK.
