In the handler for the button press, put something along these lines:

RECT stNewPosition;

// setup the new position for the bitmap (this can also resize it)
stNewPosition.top = 50;
stNewPosition.left = 50; // etc...

// this moves the bitmap only
GetDlgItem(IDB_YOUR_BITMAP)->MoveWindow(&stNewPosition, TRUE);

I think you can move the image off your dialog with this - effectively making it vanish so beware.

Simon

Dear Friend:

Thank you first.

It comes another question for me.

How come if I want to move Bitmap by implementing the DC ? Can you please show me the way?

Thanks

Userdefined ToolBar hiding

If by DC, you mean device context, I am sorry but I don't know as much about this as I always use move window.

However, I know to get the device context you would do:

CDC * pDeviceContext = NULL;
pDeviceContext = GetDlgItem(IDC_YOUR_CONTROL)->GetDC();

Then you'll have to look in the MSDN for a CDC function that moves the image.

i'm not sure if i got that right. you've got a CToolBar obj and want to hide / show it?
use CWnd::ShowWindow() with SW_SHOW / SW_HIDE.

hope this helps

Hi..
You are absolutely right!
I have a CToolBar object which needs to be hide/show as we click on menu item VIEW->ToolBar...i tried with ShowWindow(SW_HIDE),but its making the toolbar inactive instead of hiding.
Could you help me to solve this issue.

i've tried it and it works.

// your obj
CToolBarCtrl m_toolbar;
VERIFY( m_toolbar.Create(WS_CHILD | WS_VISIBLE | CCS_NOPARENTALIGN |
CCS_NORESIZE | TBSTYLE_FLAT | TBSTYLE_TOOLTIPS, CRect(10, 10, 100, 100),
this, AFX_IDW_TOOLBAR) );

// later on
m_toolbar.ShowWindow(SW_HIDE);

i rather use the CToolBarCtrl class, but if you don't want to, you can use CToolBar::GetToolBarCtrl() to get the CToolBar's underlying CToolBarCtrl class.

Hi Philipp Roesch,

This is the code iam following...

IN .H FILE

CToolBar m_Annot;

IN .CPP FILE(OnCreate() function)

if (!m_Annot.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_ALIGN_LEFT
| CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY) ||
!m_Annot.LoadToolBar(IDB_BITMAP10))
{
TRACE0("Failed to create toolbar\n");
return -1; // fail to create
}

IN THE MENU HANDLING FUNCTION WHERE I NEED TO SHOW AND HIDE TOOLBAR

m_Annot.ShowWindow(SW_HIDE);

I tried to use CToolBar::GetToolBarCtrl(), but its not working....

ahhh, ok!
write this:

IN .H FILE

CToolBar m_Annot;

IN .CPP FILE(OnCreate() function)

if (!m_Annot.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_ALIGN_LEFT
| CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY) ||
!m_Annot.LoadToolBar(IDB_BITMAP10))
{
TRACE0("Failed to create toolbar\n");
return -1; // fail to create
}

m_Annot.EnableDocking(CBRS_ALIGN_ANY);
EnableDocking(CBRS_ALIGN_ANY);
DockControlBar(&m_Annot);

IN THE MENU HANDLING FUNCTION WHERE I NEED TO SHOW AND HIDE TOOLBAR

m_Annot.ShowWindow(SW_HIDE);
