Is there an easy way to fix a path -- so that it matches the filesystem?

"C:\DOCUMENTS AND SETTINGS\PETER" to fix to "C:\Documents And Settings\Peter"

a bug -- it remains a problem because this information got persisted into storage.

I found a way to fix it:

wstring CPathTools::FixPathToMatchFileSystem( const wstring& path )
{
TCHAR ShortPath[_MAX_PATH];
GetShortPathName( path.c_str(), ShortPath, sizeof(ShortPath)/sizeof(ShortPath[0]) );

TCHAR LongPath[_MAX_PATH];
GetLongPathName( ShortPath, LongPath, sizeof(LongPath)/sizeof(LongPath[0]) );

return _T2W(LongPath);
}

btw, did you know that windows didn't care about case in folders names ?

in your explorer, just paste C:\DOCUMENTS AND SETTINGS\PETER and see if it doesn't go to C:\Documents And Settings\Peter

GetNextDlgTabItem? Do this fails sometimes or do I'm doing something wrong?

2-May-07 8:21

duh.

The software I am working on deals with file synchronization. I scan the disk and I get change notifications -- and I report these to a server that puts them into a database...

Server is happier and faster when file/path names are consistent.

Hello all,

I've subclassed a Cedit control just in order to be able to jump to the next control (with WS_TABSTOP) each time the user press the DOWN ARROW and to go to the previous control (with WS_TABSTOP) each time that the user press the UP ARROW.

well I'm using something like this in my subclassed control:

void CTAMEdit::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
  switch (nChar)
  {
    case VK_UP:
    {
      GetParent()->GetNextDlgTabItem(this,TRUE)->SetFocus();
      return;
    }
    case VK_DOWN:
    {
      GetParent()->GetNextDlgTabItem(this)->SetFocus();
      return;
    }
    case VK_RETURN:
    {
      FinishEditing();
      return;
    }
  }
  CEdit::OnKeyDown(nChar, nRepCnt, nFlags);
}

As you can see this is a very easy thing... but when I'm going forward (VK_DOWN) everything goes perfect, but when I'm going backwards (VK_UP) the focus enters into a MSChart that I have as the last control in my taborder. (I mean that the focus should bypass that control as it does when I go forward, but it don't).

Any idea? this is not critical, so I'm not very worried on that, but I'm being curious...

PS: I'm not handling cursor keys in any other place of my application.

As always thank you in advance...

If the parent window is a dialog, what happens if you use this...

// Move focus to Next
GetParent()->PostMessage(WM_NEXTDLGCTL, 0, 0);

// Move focus to Previous
GetParent()->PostMessage(WM_NEXTDLGCTL, 1, 0);

Much better...

And moreover I've seen why this was failing... of course my fault... Blush | :O

I had subclassed two type of controls and one of them was not correctly subclassed.

Thank you for your answer.

Hi guys..
Pls help,how to i display a text of words on "edit control" when i press a button.

Pls advice.

Thks.

link a variable to that CEdit, that variable can be a "control variable" or a "value variable", if it is a control variable, you can do something like this:

CEdit m_Sample;
m_Sample.SetWindowText("");

if you prefer to use the value variable you can use that:

Cstring m_Sample = "";
UpdateData(XXXX); => I never remember if here I must use TRUE or FALSE... one of them is the good one...

Hope this helps.

Regards.

PS: in order to make those variables I'm sure that on the dialog you can right click over the control and select add variable or something like this... I've never used VC2003, only VC6 and a little bit 2005...

detecting a window within another window

I am trying to write an app using MFC which allows me to drag small dialogs around and drop them in static windows. The idea is, the dialogs represent workers and the static windows represent a work position. The problem I am having is when I drop the second dialog in the same static window, it simply overlaps the first dialog so you can't tell there are two dialogs ( or three or four etc.).
I have been using this code to try and detect when the static has a dialog in it:

void CBoxes1Dlg::OnLButtonUp(UINT nFlags, CPoint point) <br />
{<br />
	CRect rect;<br />
	CWnd *pWnd1;<br />
	CPoint pt;<br />
	int y=0;<br />
<br />
	CWnd *pWnd = ChildWindowFromPoint(point);<br />
	if(pWnd!=NULL) {<br />
		pWnd->GetWindowRect(rect);<br />
		ScreenToClient (rect);<br />
		pt.x=rect.left+5;<br />
		pt.y=rect.top+5;<br />
		pWnd1=pWnd->ChildWindowFromPoint(pt,CWP_ALL);<br />
		<br />
		if(pWnd1 == pWnd){<br />
			// no dialog here<br />
		}else{<br />
			// must be a dialog so adjust pt.x and pt.y<br />
		}<br />
	}<br />
	m_person->SetWindowPos(&CWnd::wndTop,(pt.x),(pt.y),0,0,SWP_NOSIZE|SWP_NOZORDER);<br />
}

This doesn't work properly.....
Anyone see the problem or think of an easier way to do it.

Thanks

waveInXXX - USB device returns MMSYSERR_BADDEVICEID

Re: waveInXXX - USB device returns MMSYSERR_BADDEVICEID

1-May-07 8:13

I am using waveIn API to retrieve specific audio device for audio input. I get correct string to identify all audio devices, including USB "webcam". However waveInOpen with WAVE_FORMAT_QUERY parameter set returns "MMSYSERR_BADDEVICEID Specified device identifier is out of range".
Any idea what is wrong here?
I would prefer to stay with waveIn.
Thanks for reading.

Re: waveInXXX - USB device returns MMSYSERR_BADDEVICEID

What are you using as a device ID (second param passed to waveInOpen())?

Re: waveInXXX - USB device returns MMSYSERR_BADDEVICEID

Thanks Mark for reply.

I am passing the int returned from combobox under USB device...
I may be 1 off since it is the last one!
Also - if the combo box is "sorted" how does that match with right device?
Basically it seems weird that waveInOpen will accept item number from combo box.But that what the doc says.

I'll work on it when I get home.

I guess passing query is still not guarantee that I got the capable device.

Mark Salsbery1-May-07 12:16

Re: waveInXXX - USB device returns MMSYSERR_BADDEVICEID

For a sorted combobox, the combobox item indexes probably won't match the wave device indexes
(unless they are already in sorted order).

You could use the combobox itemdata to store the device index.
Use the index returned by the CB_ADDSTRING message in a CB_SETITEMDATA, setting the itemdata
to the device index.

Use CB_GETITEMDATA on the selected combobox item to get the chosen device index.

Re: how to plot the values

1-May-07 16:22

Mark,
the "problem" was in sorting the combobox.
All legal input devices now work fine.
Only the modem imput line gives an error but I am too tired to find wich one and really dont need it now anyway.
USB is 3rd on the list and not the last when sorted.
Thanks for your help.
