Process the WM_INITMENU or WM_INITMENUPOPUP and disable the items you want.

How move a component ?

3-Jun-01 3:26

I don't find response about that in the French web, therefore I try here...

I can move the components with the mouse in the dialog box editor, of course, but I would like to manage to specify my picture position (x,y) with the code.
With Delphi, it's MyPicture.Left=x and MyPicture.Top=y, and with Builder C++, it's MyPicture->Left=x; and MyPicture->Top=y; but with Visual C++ I don't find the members Left and Top for the my Control CStatic...

Do you know ?

Thanks...

Hi Pierrick,

You have to use MoveWindow() method of CStatic class. Refer MSDN for a arguments of this method.

Hadi, you are either the worlds most amazing programmer, or you ask a lot of questions about things you don't go on to use Smile | :)

I'm not sure if I've read the question right, but an MPEG codec will encode a video/audio stream into an MPEG format ( live DVD, VCD, &tc ), and decode it to allow it to be played. For example, if you were to get hold of my music video collection, it would not play until you installed the DivX Wink | ;)

codec. You can use it to write video capture software - to write a player you can use Media Player as a COM object. My encoder of choice is a free ware open source thingy called Virtua Dub. I'd suggest getting the source if you want to know more about video work.

the Background in Edit Control

2-Jun-01 19:45

Hello,

I created several Edit Controls with semi-transparent bitmap image
background. It uses "WM_CTLCOLOREDIT" with returning prefer Bitmap brush.
( Also setting Font, SetBrushOrg in CTLCOLOREDIT )
It works perfectly on WinNT/2000.
But on the Win9X, SetBrushOrgEx() seems doesn't work in WM_CTLCOLOREDIT Frown | :(

And I can't try to CreatePatternBrush() for whole my-app-window,
because it's large. So I'm using each Edit-Control brush method.

Do you know how to control Brush Origin at Edit Control or WM_CTLCOLOREDIT?

I'm sorry I'm not good to say in English.

Many thanks in advance. Cry | :((

Moving Focus To A Control

Hello,

I have a dialog box that I reuse to enter and modify information in my program. What I would like to accomplish is to have the focus placed on a certain control when the dialog is being used to enter information and another different control when it is being used to modify information. How would I go about doing this? I've been searching through the MSDN but haven't had any luck figuring out how to move the focus at all. Right now it's just defaulting to the first tab stop on the dialog. I really appreciate any help. Thanks!!

Hello, the codegurus around the world.

In order to change the input focus on Dilaog,
we can use CWnd::SetFocus() or CDialog::GoToDlgCtrl(CWnd*) member functions.

However, if you validate some data in some control, and change the input foucs,
you have to write your own code.

Issue is when the application will change the input foucs to the conrol?
When the user push enter key, or some control loses its own focus...

Have a nice day!

Hi Onishi.
If i using SDI and CFormView in my program, so how can i set the focus for controls ?

Hello, the codegurus around the world.;)

If you add "Please" to your message, someone else may help you more. Roll eyes | :rolleyes:

"Write your own code" means that we sometimes work more than we expect.
SetFocus() doesn't work correctly if we figure out the order of the input foucs.
Your question is this example. Dead | X|

One control should be on CMyFormView.
I try to set the input foucs to the edit box called IDC_ZIP after I close
Sort dialog if I open Sort Dialog by clicking the menu item.

void CSortDialog::OnCancel() 
{
	// Get CMainFrame CWnd to use GetActiveView();
	CMainFrame* pFrame = (CMainFrame*)AfxGetMainWnd();
        ASSERT(pFrame);
        // Get CWnd of CMyFormView;
	CMyFormView* pView = (CMyFormView*)(pFrame->GetActiveView());
        ASSERT(pView);
        // Try to set the input foucs the edit control called IDC_ZIP;
	pView->GetDlgItem(IDC_ZIP)->SetFocus();
        // But the above code did't work, so I use BOOL m_bSetFocusToZipCode;
        // Since the first tab order control gets the input focus;
	pView->m_bSetFocusToZipCode = TRUE;

	CDialog::OnCancel();
}

void CMyFormView::OnActivateView(BOOL bActivate, CView* pActivateView, CView* pDeactiveView) 
{
	// bActivate = TRUE means that CMyFormView gets the foucs;
	if (bActivate && m_bSetFocusToZipCode) {
                //This works to change the input foucs to IDC_ZIP here;
		GetDlgItem(IDC_ZIP)->SetFocus();
		m_bSetFocusToZipCode = FALSE;
	}

	CDaoRecordView::OnActivateView(bActivate, pActivateView, pDeactiveView);
}

Hum, in fact, this code seems not to be practical since we have to add all BOOL flag
to change the input foucs to all controls on FormView. Dead | X|

But, now we understand that SetFocus() doen's work if we misunderstand how the input foucs
is executed in the process of Window message.
In this case, the tab order of the control on FormView seems to overwrite the code of
void CSortDialog::OnCancel() to set the input focus.

Have a nice day!

Hello, the codegurus around the world.;)

Well, I missed your word - "Please write the code".

You're lucky since I have my time to have some experiment and
I have my own code for the formview project.

However, if I don't have this project, I have to spend my time - maybe a couple of hours
to create the same enviroment project. Cry | :((

Since I am done this test about 20 minutes, it wasn't tough for me.
(However, the first approach did't work, I'm so Eek! | :eek:

)
(Or someone may have the better answer.)

My point is that if we have the same project which someone asks us, we can answer
the question or make some test easily. Otherwise, we have to spend a least couple of hours
since we have some responsibilty to our answers. Cry | :((

(Or, the other super-programmers can answer these easily.? Dead | X|

)

So, I often told the people at the codegurus or codeproject, show your code or
narrow your question more. Cool | :cool:

Have a nice day!

Outlook address book???

Hi,

Wondering if anyone knows (if its possible) how access the dialog that displays the list of recipients from an Outlook address book. More specifically, its the "Select Names" dialog you get when you click the "To" button on a new message. Can I also select the recipients and put their email addresses in variables?

Thanks in advance,

Matt

I'm sure you should use Outlook Object Model to get a names from address book. Please refer to MSDN how to get it work.

SendMessage

Ok, a simple question.
I am using SendMessage to send a WM_NOTIFY message.

LRESULT test = GetParent()->SendMessage(WM_NOTIFY, ... );

If the parent window handles the WM_NOTIFY message the return value is set to whatever. My question is, if the parent window does not handle the message, is the returned value always zero (as my tests seem to indicate) or is it undefined Confused | :confused:

The return value is whatever DefWindowProc() returns. From skimming a few WM_NOTIFY pages, it looks like the default behavior is always indicated by a return of FALSE (0).

Hot Keys

I am unable to set any Hot keys in my SDI MFC application.
Accelerators like alt+_... works fine, but none of the custom added ones.
