Re: watching unicode strings during debugging

The default symbol for a string is s. Use su instead. There's also st which can be used for ANSI or Unicode depending on what you have in autoexp.dat. These symbols are used in the Watch window after the variable that is being watched.

I seem to remember that there's an option ( a checkbox) somewhere in the preferences that let you see unicode strings in the debugger.

m_pMainWnd is NULL in CWinApp::Run

Hi,

In my app::InitInstance()

<br />
{<br />
  ...<br />
  CMyDlg dlg;<br />
  m_pMainWnd = &dlg;<br />
  dlg.DoModal();<br />
  <br />
  return TRUE;<br />
}<br />
<br />
The 'CMyDlg' has an internal timer that gets activated after 1 second, and starts executing some actions.  After done, the timer is killed and 'CDialog::OnOK' is called.  This gets the dialog closed.<br />
<br />
In the app i need to return TRUE, else i got exit code != 0.  But now, i get this ennoying warning:<br />
Warning: m_pMainWnd is NULL in CWinApp::Run - quitting application.<br />
<br />
Any way to get this (annoying) warning out of the program?<br />
<br />
Greetings,<br />
Jens

"Typically, you set this member variable when you override InitInstance. In a worker thread, the value of this data member is inherited from its parent thread."

Can you show the complete code for InitInstance up to dlg.DoModal();?
Also, why are you writing to this variable?

Dialog based apps must return FALSE from their CWinApp::InitInstance function.

Hi,

I tried to return false, but then the exit-code of the process is '1'. The exit-code needs to be '0'. I removed the m_pMainWnd = &dlg; line alsoo.

You need to use:

BOOL CMyDialog::InitInstance()
{
    return FALSE; // so that the application's message pump doesn't start
}
 
int CMyDialog::ExitInstance()
{
    return 0; // the application's exit code
}

HideWindow

Hello,

I created a custom scrollbar. I need it to be hidden when the page size is larger than the range.

I used void ScrollBarEx::OnShowWindow(...) fn (mapped) to track the visibility of the scrollbar wnd.

I got the message callback to this fn when the scrollbar wnd is being shown.

But I can't hide the window from fn.

void ScrollBarEx::OnShowWindow(BOOL bShow, UINT nStatus) 
{
	// just for testing
	ShowWindow(SW_HIDE);
}

What steps should I do?

For that you have to enumerate the values under the RUN subkey....

or if you want to know who to distinguish in your program then This link quite similiar to that :-ow to start at Program which start Hidden on Windows startup but Visible other wise?[^]

One way is to take help of registry. But again this will help while installation as you wull have admin rights then.

See if there is an application associated with the .PDF extension using FindExecutable() or AssocQueryString(). If there is, compare its name to AcroRd32.exe.

I'd think you'd want to make the more general check to see if any app is associated with the pdf extension. Since the intent is simply to view the file it shouldn't matter if the user has the acrobatreader installed, is a graphics designer and has the full fledged acrobat application, or is using a 3rd party pdf reader instead.

You've confused the compiler. remove lines of your code until it compiles, then look at the code you removed and see what is wrong.

If you're using DirectX, you can create a Filter to draw over the video. You can't put a control over the video to draw on it.
