<P>Hi,
<BR>I have a Global variable in my application header file it is of type CCAudio which is my audio library that contains my Cd Audio functions.
<P>i have a seperate modeless dialog box which is called from my cview.cpp file. it simulates the cd Player simple functions, such as play, pause, etc.... .
<BR>I added a function to get the global variable and use it :
<P>CCDAudio CAudioDlgBar::GetAudio()
<BR>{
<BR> CAudioApp *app = (CAudioApp *)AfxGetApp();
<BR> return app->m_CDAudio;
<BR>}
<P>So in the rest of my class imlpementation i used :
<P>void CAudioDlgBar::OnStop()
<BR>{
<BR> GetAudio().Stop ();
<BR>
<BR>}
<P>For some reason none of the buttons of the dialog box are getting enabled which means i cant press button Stop, Play.... .
<P>before i made m_CDAudio Global everything was fine,i had it in my CAudioDlgBar.h and the Stop function looked like this :
<BR>void CAudioDlgBar::OnStop()
<BR>{
<BR> m_CDAudio.Stop ();
<BR>}
<P>Does any one know or have a clue on what the problem is.
<P>My main app class is :
<P>class CAudioApp : public CWinApp
<BR>{
<BR>public:
<BR> CAudioApp();
<BR>// Overrides
<BR> // ClassWizard generated virtual function overrides
<BR> //{{AFX_VIRTUAL(CAudioApp)
<BR> public:
<BR> virtual BOOL InitInstance();
<BR> //}}AFX_VIRTUAL
<P> CCDAudio m_CDAudio;
<BR>
<BR>// Implementation
<P> //{{AFX_MSG(CAudioApp)
<BR> afx_msg void OnAppAbout();
<BR> //}}AFX_MSG
<BR> DECLARE_MESSAGE_MAP()
<BR>};
<P>Thank you very much in advance !!!!!
<P>charbel.
