Hi all,

I have a set of property pages on a property sheet. I am trying to add a page to the sheet and change the title, but the title does not change.

If I do:

//AddPage(thepage);
//SetActivePage(thepage);

SetWindowText("TEST");
CString strTest;
GetWindowText(strTest);

Then strTest is changed to "TEST" correctly, but the text does not show up on the control.

Am i missing something?

Thanks and Regards,
Simon

See if MSDN article Q141487 helps. There's also the CPropertyPage protected member, m_strCaption.

only 1 control catches tooltip?

This is the situation:
ON_NOTIFY_EX(TTN_NEEDTEXT, 0, OnToolTipNotify )
EnableToolTips(TRUE); is the first statement in OnInitDialog

<br />
BOOL DlgFlexListFormatColumns::OnToolTipNotify(UINT id, NMHDR *pNMHDR, LRESULT *pResult){<br />
	//pTTT->szText ==> maximum 80 characters<br />
	CString tooltiptext2display;<br />
	tooltiptext2display = "";<br />
	TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR;    <br />
	UINT nID = pNMHDR->idFrom;<br />
    if (pTTT->uFlags & TTF_IDISHWND)   {<br />
        // idFrom is actually the HWND of the tool<br />
        nID = ::GetDlgCtrlID((HWND)nID);<br />
		switch(nID){<br />
			case IDC_STATIC_LINESPERROW: tooltiptext2display.Format(IDS_LINESPERROW);<br />
			break;<br />
			case IDC_EDIT_NROFLINES:	 tooltiptext2display.Format(IDS_LINESPERROW);<br />
			break;<br />
			default:<br />
			break;<br />
		}									//end switch<br />
		strcpy(pTTT->szText, tooltiptext2display);<br />
		return(TRUE);<br />
	}										//end if<br />
	else{ return FALSE; }					//end else<br />
}											//end method OnToolTipNotify<br />

and in the header:

afx_msg BOOL OnToolTipNotify(UINT id, NMHDR *pNMHDR,LRESULT *pResult);<br />

QUESTION:
There is only 1 control in my dialog which catches (and thus shows) a tooltip. All the rest does nothing.
What did I do wrong?

tnx for your help...

Change this to:

ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTA, 0, 0xFFFF, OnToolTipNotify)

Does that imply that OnToolTipNotify() is called only for that one control? Are the other controls obscured by anything, including a group box?

Well now you mention it: yes, they are all surrounded by a groupbox.
(that one control isn't surrounded)

I didn't know that that would be problem?
Why's that?

The group box control needs to be behind the other controls. Even though it appears as a skinny line surrounding the controls, it is actually obscuring them as far as tooltips are concerned. In the resource editor, change the tab order of the controls such that all the controls within the group come first.

If you can trim the code down to something very small and still be able to reproduce it, feel free to send the project to me and I can take a look.

I see your point. If I make the Group box invisible, the tooltips appear.
However the three groupboxes in my dialog have the three last numbers of tabstop and the tooltips do not appear. (enabling or disabling the tabstop propetie does not help)

There's no need to make it "invisible." Just ensure that it is behind all the other controls.

I don't quite understand this.

Class hierarchy question...

vmaltsev8-Jul-04 1:57

8-Jul-04 1:57

Hail everyone,

Let's say I have two classes, A and B, as well as two interface (abstract) classes for them, iA and iB. Class B derived from class A and interface iB, interface iB derived from iA, so we have,
class iA {
vitrual method AA
}
class A: public iA {
method AA
}
class iB: public iA {
vitrual method BB
}
class B: public A, public iB {
method BB
}

By doing this I want to be able to access methods of class B (and A in it) through interface iB, but, I can't do so. Compiler justly says "pure vitual function AA was not defined in B"

So, couls you please explain to me how this hierarchy should look like?

Thanks in advance, any suggestion would be helpful.

Re: Class hierarchy question...

Because class B inherits from both class A and class iB, it has to deal with two different vtables. Therefore you need to provide method AA of class iA in both vtables and that is the source of the error message: the implementation for class iB is missing.

Just write a wrapper method AA in the class B, calling A::AA; this will redirect iB::AA to A::AA.

Processing the LVN_KEYDOWN notification will work, I've tested it. You just need to check if ((LPNMLVKEYDOWN)lParam)->wVKey=='F' and then check the state of the control key, it is pressed when the test (GetKeyState(VK_CONTROL) >> (sizeof(SHORT)-1)) returns non-zero.

AND

pWnd = (CWnd*)GetDlgItem(IDC_STOP_ROBOT);<br />
pWnd->EnableWindow(FALSETRUE); // sorry

if it doesn't work try rebuilding all.
