2 windows controls one above the other

In addition to DavidCrow's reply - if the parameter for SetItemData() is a DWORD_PTR,
use that instead of a DWORD in the cast.

Hello,

I have a childframe derived from CMDIChildWnd on which there are 2 windows controls. One window control is a list box and another is an edit box . The list box is above the edit box.

When I keep the mouse cursor on the list box it appears as if the the mouse cursor is on the edit box and when I click the edit box gets clicked.

How can I bring the list box on the foreground and send the edit box in the background?

You can use m_list.SetWindowPos( &wndTop, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOACTIVATE );

And I expect some painting issues... Smile | :)

m_edit.ModifyStyle( 0, WS_CLIPSIBLINGS ); may solve that issue.

Dont forget to let me know the results... Wink | ;)

I presume the two controls have the same coordinates, and you are swapping between them?

In addition to changing the Z order as NS17 showed you, you should also make the one you're not using disabled,

GetDlgItem (IDC_MYNEGLECTEDCONTROL)->EnableWindow (TRUE / FALSE)

, or the user will end up selecting them using TAB - and they will be very puzzled why the things they are typing don't show up...

Iain.

are you still on about this. your best bet is to get the window sizes and adjust the edit box such that it doesnt overlap the listbox. am I gunna give you the code to do that ? no. GetWindowRect(), GetClientRect(), MapWindowPoints(), SetWindowPos(). Maybe in response to a WM_SIZE message.

the title says it all. i just want to show the text and disable the option that user can input some text in the rich edit box control

thanx

You can call SetReadOnly() API

You can disable or read only your control(Richedit) with set these opition (disable or readonly) on the property window of control.

Does it need to be read-only all of the time? If so, do that in the resource file rather than at runtime via SetReadOnly().

How can I resize Rich Edit Box in the code? I already know the width and the height.

thanx

Use MoveWindow or SetWindowPos

I tried this:

void CTextView::OnSize(UINT nType, int cx, int cy)
{
CFormView::OnSize(nType, cx, cy);
m_RichEdit.SetWindowPos(this, 0, 0, cx, cy, SWP_NOMOVE);
}

program will not start beacuse i get some message. I think the problem is in "this" in SetWindowPos. My base class is CFormView. Any ideas?

Nishad S31-Aug-07 2:16

31-Aug-07 2:16

That may be due to the following reason.

m_RichEdit will not be subclassed when OnSize is called for the first time. This usually happens in the dialog based applications.

In your case, you can do as...
GetDlgItem( IDC_RICHEDIT )->SetWindowPos(this, 0, 0, cx, cy, SWP_NOMOVE);

Hope it will work...

One thing i ignored... Frown | :(

Why are you passing the "this"? It is not needed. You can set it as NULL and modify it as ( 0, 0, 0, cx, cy, SWP_NOZORDER | SWP_NOMOVE )

This is safe:

void CTextView::OnSize(UINT nType, int cx, int cy)
{
    CFormView::OnSize(nType, cx, cy);

   if (m_RichEdit.GetSafeHwnd())
      m_RichEdit.MoveWindowPos(0, 0, cx, cy);
}

cannot convert parameter 1 from 'struct HWND__ *' to 'const class CWnd *'
this is the message I get when I try your solution.
Grhhhhh.... This is driving my crazy......

Mark Salsbery31-Aug-07 5:32

I'm sorry - it was my mistake - I didn't delete the "Pos" when I changed the
SetWindowPos to MoveWindow Blush | :O

void CTextView::OnSize(UINT nType, int cx, int cy)
{
    CFormView::OnSize(nType, cx, cy);

   if (m_RichEdit.GetSafeHwnd())
      m_RichEdit.MoveWindow(0, 0, cx, cy);
}
