just make a dialog with mfc-wizard.
add message function like this

void CTest::OnLButtonDown(UINT nFlags, CPoint point)
{
PostMessage(WM_NCLBUTTONDOWN, HTCAPTION, MAKELPARAM(point.x,point.y));
CDialog::OnLButtonDown(nFlags, point);
}

and exacute it.

1) click the client area of dialog with left mouse button.
2) move it toward screen top
3)when the some part of dialog is in off-screen, release mouse left button.
4)automatically the dialog is moved again to screen area. <= it is my problem.

normal window acts like this.
how can I disable 4) action?

I want to prevent the dialog from automatically moving back onto screen.

thank you in advance.

Use DM_REPOSITION message to move dialog back onto screen.

Are either of these plausible?

1) Don't process the WM_LBUTTONDOWN message, or 2) Don't post the WM_NCLBUTTONDOWN message

Re: Taking more time to create active-x component

sir,

I am working on vc++ 7.0 project and it is based on MDI Compound document view architecture and I am trying to embed an active-x component into my project.
why it takes more time, when i try to create a component on the display document for the first time. The same component when i try to create subsequent time it takes less time. could you please throw some light on it.
Is there any efficient way to write code by which we reduce time while creation of Active-x component.

Below is the code which creates the component

CView* pActiveView = pInterfaceObject->GetActiveView();//getting the handle of active view

if (pActiveView)
{
COleServerDoc* pActiveDocument = (COleServerDoc*)pActiveView->GetDocument(); //assigning the handle to the COleServerDoc.
ASSERT_KINDOF(COleServerDoc, pActiveDocument);

m_pClientItem = new COleClientItem (pActiveDocument,this);//creating a container
}
m_pClientItem->CreateNewItem((REFCLSID)(clsid)); //creating the Active X control through known classid
ASSERT_VALID(m_pClientItem);

if(m_pClientItem)
{
IDualChart *pDualChart;
if (FAILED(m_pClientItem->m_lpObject->QueryInterface(__uuidof(pDualChart), (void**)&pDualChart)))
{
AfxMessageBox(_T("Query interace failed"));
return bStatus;
}
m_pChart.Attach(pDualChart);

Thanks & Regards,

Hi,

I have a character array and want that to be assigned to cstring object, how can i do that.
I have tried the assignment operator, but it is copying upto end line character, and leaving the other character.
Does any one know about that?

Warm Regards,
Mushq

Look at the constructor of the CString class,

CString( const unsigned char* psz );<br />
throw( CMemoryException );

That's sure a complicated way to do this:

CString val;
...
val = "Hello";

or

CString val("Hello");

So you have a NULL inside your array. If it were possible what you want to do, CString wouldn't be a string class; A string should terminate with NULL symbol ('\0') to make itself be a string.

Wouldnt it be enough to put the Logo in the Output Window via BitBlt.

If you get the stream it isnt yours, so you cant do your Logo in it. Confused | :confused:

Thanks for your reply. But the thing is that I am not using MFC. I have to find a way to change the Owner of a Popup Window using Win32 APIs. Oh and SetParent() doesn't work. Frown | :(

Why not?

It's not a modal dialog popup window is it?

Well, from what I have read, SetParent() just sets the Parent of a Window and the Owner of a Window cannot be changed once it is assigned during creation. I was just hoping that maybe someone had a hack through which he/she could change the owner of a Window.

No. It is just a plain Popup Window.

You haven't mentioned MFC but that's the only place I know of where the concept of an owner window
applies.

The CWnd::GetOwner() and CWnd::SetOwner() methods are available for working with window ownership.

Sorry it took so long to reply!
