1- use the spy to get the caption of the target window
2- use FindWindow to get the handle to this parent window
3- use EnumChildWindow(given the parent window handle) to loop onto the child windows of that parent window(like button,label,..etc
4- use SendMessage to fire the action of any child window.
any function i listed,see its def. from the MSDN,and its details..
by the way..i had automated so many other applications windows..

I've added an accelerator, then Ctrl+W then selected my main Dlg class.

However, when I run my program and press the keys, the accelerator doesn't work...

thanks for help

Have you called LoadAccelerators() in the dialog's constructor? You'll also need to override the PreTranslateMessage() method and call TranslateAccelerator() accordingly.

Hmm, can you give me an example please?

I'm kinda new...

CTestDlg::CTestDlg(CWnd* pParent /*=NULL*/)
: CDialog(CTestDlg::IDD, pParent)
{

//{{AFX_DATA_INIT(CD2HackKitDlg)
// NOTE: the ClassWizard will add member initialization here

//}}AFX_DATA_INIT
// Note that LoadIcon does not require a subsequent DestroyIcon in Win32
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
}

thanks

I just completed an application for a company and they want a 30 day trial version made for demos.. can anyone point me in the right direction on how do add 30 day support? I have thought of looking at dates on files, creating reg keys etc.. but they want to make sure turning the clock back will not effect the time out. Any ideas?

One thing you might do is to have your software quit after 30 minutes, 60 minutes of use. and always, always remove all save functionalities from your demo versions.

If you can't do that and want a full version with a 30 days limit, remove some functionalities, restrict/disable saving, ...

CPropertyPage / CPropertySheet problem

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?

V.8-Jul-04 2:16

8-Jul-04 2:16

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)

V. wrote:

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.
