I think that your inquiry is best posted in the "General Discussions" forum, not in the "Visual C++" forum as this inquiry does not reference MFC or C++.

Happy Programming and God Bless!

Audio input level

I need to send out canned audio message from my computer to a pagger. The problem is that other human users may be using the pagger. I need to monitor the pagger audio output and wait for a period of no activity. The pagger audio output is hooked up to the mic input of my Sound Blaster. Unless it's easier then it looks, I'd rather not have to figure out how to decode the wave file and somehow determine the input level. Is there an easy solution to this problem?

Running in Background?

Is there a way to launch a PDF from an application
and then programmatically print it without the end-user
seeing all this going on?

I can ShellExecute, but the whole things displays. I want it to be hidden. Most importantly tough, I can't
figure out how to programmatically click File/Print/Ok
on the Adobe Reader from a different application.
Any ideas?

Please, any response any one can give me will be greatly
appreciated.

Sincerely,
Danielle (an overworked graduate student)

You could use the "print" verb (instead of "open") when you call ShellExecuteEx(). This will cause the standard Windows print dialog to open, bypassing the Adobe Acrobat GUI.

I don't know how to directly print to the default printer without showing the print dialog. Frown | :(

Hello
I've got a CTreeCtrl. When i double-click on one of the items, i want to get in a CString the string of where i doubleclicked.

the following code

CString temp;
HTREEITEM hItem = m_tree.GetSelectedItem();
            temp = m_tree.GetItemText(hItem);

gives me a runtime error.
any ideas?
thanks!!

Perhaps hItem is NULL? What's the run-time error you're getting?

HI..Dear..
You need to trap event selChanged & in that even you can get value.. e.g.: I'm traping tree in view by using following code..you can do simmilar
bye

void CLeftFirstTreeView::OnSelchanged(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*)pNMHDR;

CString aa;
aa.Format("%s", GetTreeCtrl( ).GetItemText(pNMTreeView->itemNew.hItem ));
MessageBox(aa);
}

Tha's it.. you can do this in tree control by traping same event...
bye again

Hi all.
I want to create a Device Installation application in Win98.

I have VC++ 6 and DDK98.
How can I use 16 bits function such as DiInstallDevice! Confused | :confused:

Results of search:
The argument to DiInstallDevice & DiInstallClass is compatible with 32-bit calling convention.

DDK98:
Extract Bin_Win98_ml.exe change name to ml.exe and copy it to VC98\BIN.
Extract Bin_Win98_ml.err change name to ml.err and copy it to VC98\BIN.

Looking at the USB examples that come with the DDK should help.

Note:
www.bluewartersystems.com has a DDK wizard that is supposed to ease the development of DDs.

mfc: load a cursor resource

Hi!, i've created a cursor with the resource editor. i want to load it when i press a button. i've tried with this code, but it doesn't work:

HCURSOR hCursor;
hCursor = AfxGetApp()->LoadCursor(IDC_MYCURSOR);

any ideas?
thanks!

This code looks well and should work nicely. Check what hCursor is, if it's something non-zero or NULL.

Of course, if you want to display the cursor, you must use the SetCursor API function, see MSDN for more.

Best regards,
Dominik

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

that's what i want to do.. to display it.
should i call SetCursor, or it is called automatically, like OnPaint or the like?

The remarks section of SetCursor in MSDN:

The cursor is set only if the new cursor is different from the previous cursor; otherwise, the function returns immediately.

The cursor is a shared resource. A window should set the cursor shape only when the cursor is in its client area or when the window is capturing mouse input. In systems without a mouse, the window should restore the previous cursor before the cursor leaves the client area or before it relinquishes control to another window.

If your application must set the cursor while it is in a window, make sure the class cursor for the specified window's class is set to NULL. If the class cursor is not NULL, the system restores the class cursor each time the mouse is moved.

The cursor is not shown on the screen if the internal cursor display count is less than zero. This occurs if the application uses the ShowCursor function to hide the cursor more times than to show the cursor.

Windows CE: Use the cursor component when targeting a platform that does not support mouse cursors. The only cursor this component supports is the wait cursor. Use the following code to set the wait cursor:

SetCursor(LoadCursor(NULL, IDC_WAIT));
Use the mcursor component when targeting a platform that does support mouse cursors. This component does not support color cursors.

Dominik

I've read this kind of tutorial in msdn:
<url=http: msdn.microsoft.com="" library="" default.asp?url="/library/en-us/winui/WinUI/WindowsUserInterface/Resources/Cursors/UsingCursors.asp">http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/WinUI/WindowsUserInterface/Resources/Cursors/UsingCursors.asp

I'm doing an mfc app, and that seems winampi, but i tried to implement what's there anyways.

first of all, in my dialog class i've got these member variables

HINSTANCE hinst;
HCURSOR hCursor;

In the constructor of the dialog i've got:

hCursor = LoadCursor(hinst, MAKEINTRESOURCE(IDC_LAPIZ_CUR));

then i've got this:

BOOL CVentanaPizarra::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message) 
{
	if (changecursor==true)
    { 
        SetCursor(hCursor); 
    } 
	return CDialog::OnSetCursor(pWnd, nHitTest, message);
}

so, when i press a button, the changecursor variable is set to true.

But it still doesn't show the cursor when i press that button
what am i doing wrong?

Ouch. You are not initializing hinst to the application instance handle.
Rewrite to:

hCursor = LoadCursor(AfxGetResourceHandle(), MAKEINTRESOURCE(IDC_LAPIZ_CUR));

  return   CDialog::OnSetCursor(pWnd, nHitTest, message);
}

You are calling the base class implementation in OnSetCursor. Rewrite to:

BOOL CVentanaPizarra::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message) 
{
  BOOL result = TRUE;
  if (changecursor==true)
  {
    if( SetCursor(hCursor) )
      result = TRUE;
  }
  else
    result = CDialog::OnSetCursor(pWnd, nHitTest, message);

  return result;
}

It is very frustrating Eek! | :eek:

, first I had 120 errors or more, than I reduced to 0 Cool | :cool:

, so I thought now my application is ready to start than I got the message: Debug Assertion Failed WTF | :WTF:
