OnUpdate and other Events

[minifiredragon]

Ok, I am now beginning to feel like a ninny.

I thought that when a dialog box closes (with Ok or Cancel) it passes an UpdateData to the next window. When I put an OnUpdate and code in there, it doesn't do anyhting. Here is what I am doing.

I have a CFormView Window starting with the appilcation (I am using an SDI w/database support). I finally got it set up so that when you push a certain key a dialog box opens up and asks you to input data via an edit box. Then you push OK (or Cancel) if you change your mind.

Now I added a static box to see if I have properly learned how to access data from a dialog box. But it never updates itself. I know it gets the data, but it never refreshes.

I used OnUpdate, and WM_SETFOCUS to update the static box when the dialog box is closed. But know.

How do I know it works?? I had this bit of code in there:

if ( m_dInsertDlg.DoModal () == IDOK )
m_sCard = m_dInsert.m_sCardNum;

and everytime I compiled the application the darn Card Number Dialog box opened up 1st, I entered my numbers and pushed ok, and it DID update the static box. But when I pushed the key to enter a card number, entered the number, and pushed OK, it never changed the static box.

I have even tried removing just the:

if ( m_dInsertDlg.DoModal () == IDOK )

It doesn't pop up the box, but it still doesn't update the static text.

So much for thinking I was actually getting somewhere in my knowledge.

In the past, I put my code in the main() section and it looped through that, right now, I have no clue where to put my code so it works like it should.

Woohoo, I figured it out.

I kept adding to my code in the on PreTranslateMessage code to look like this:

BOOL CICServerView:reTranslateMessage(MSG* pMsg)
{
if(pMsg->message == WM_KEYDOWN && pMsg->wParam == 'I')
{

//Initialize InsertDlg window
CInsertDlg dlgInsertDlg;

//OPen Window
dlgInsertDlg.DoModal();
m_sCard = dlgInsertDlg.m_sCardNum;
UpdateData(FALSE);
return TRUE;
}

return CFormView:reTranslateMessage(pMsg) ;
}

And it updated like I wanted it too. Is this the proper place to put it thought??

Depends on your definition of "proper". That's certainly not how i would do it but i've been developing with MFC for.... ummm since it started, so i know my way around it pretty well.

Some people would say, "if it works... it's all good". ;-)

May I ask who you would go about it?

<points at stack of notes> That is from you already.

Well it would go back to the starting point really. See I would have created a command on the application menu somewhere for whatever your doing with that dialog etc. Once you have a menu command you simply create a command handler for it. The command would potentially have a toolbar button as well and it seems a requirement is for the command to be invoked by keypress as well so I would create an Accelerator Key for the command. This of course means you never overrode PreTranslateMessage() to start with.

So the upshot is there would be something like:

void CICServerView::OnCardInsert()
{
   //Initialize InsertDlg window
   CInsertDlg dlgInsertDlg;

   //OPen Window
	if( IDOK == dlgInsertDlg.DoModal()){
		m_sCard = dlgInsertDlg.m_sCardNum;
		UpdateData(FALSE);
	}
}
