Windowless ATL ActiveX Control for Multimedia Applications

This ATL ActiveX framework is suitable for serving as the bearer container for Windows Media Player, Flash, and sliverlight animations. The entire framework is distributed in the windowless folder, with 6 files in total. Architecture:

UseAdobe Flash PlayerAs a child Control

  

MainCodeAs follows:

Class cmaindlg: Public caxwindowlesshost <cmaindlg>

Lresult cmaindlg: oninitdialog (uint/* umsg */, wparam/* wparam */, lparam/* lparam */, bool &/* bhandled */)
{
// Center the dialog on the screen
Centerwindow ();

// set icons
hicon = (hicon): LoadImage (_ module. getresourceinstance (), makeintresource (idr_mainframe),
image_icon,: getsystemmetrics (sm_cxicon),: getsystemmetrics (sm_cyicon), lr_defaultcolor);
seticon (hicon, true);
hicon hiconsmall = (hicon): LoadImage (_ module. getresourceinstance (), makeintresource (idr_mainframe),
image_icon,: getsystemmetrics (response),: getsystemmetrics (response), lr_defaultcolor);
seticon (hiconsmall, false);

tchar szpath [max_path] = {0};
If (: getmodulefilename (null, szpath, max_path)> 0)
{// positioning .swf file
lptstr pszsep = _ tcsrchr (szpath, tchar ('\');
pszsep ++;
* pszsep = 0;
: stringcchcat (szpath, max_path, _ T ("construction.swf");
}

// initialize Flash Player (shockwave. SWF)
hresult hr;
activexsite * psite;
psite = caxwindowlesshost : getcontrolsite (idc_shockwaveflash ); // obtain the Flash Player sub-Control
If (psite! = NULL)
{< br> ccomqiptr spflash = psite-> activexcontrol ();
hR = spflash-> put_wmode (ccombstr ("Transparent"); // set "Transparent"
hR = spflash-> put_movie (ccombstr (szpath )); // set the video source file
}< br> return true;
}

UseWindows Meida playerAs a child Control

The main code is as follows:

Lresult cmaindlg: oninitdialog (uint/* umsg */, wparam/* wparam */, lparam/* lparam */, bool &/* bhandled */)
{
// Center the dialog on the screen
Centerwindow ();

// Set icons
Hicon = (hicon): LoadImage (_ module. getresourceinstance (), makeintresource (idr_mainframe ),
Image_icon,: getsystemmetrics (sm_cxicon),: getsystemmetrics (sm_cyicon), lr_defaultcolor );
Seticon (hicon, true );
Hicon hiconsmall = (hicon): LoadImage (_ module. getresourceinstance (), makeintresource (idr_mainframe ),
Image_icon,: getsystemmetrics (sm_cxsmicon),: getsystemmetrics (sm_cysmicon), lr_defaultcolor );
Seticon (hiconsmall, false );

// Initialize Windows Media Player
Hresult hr;
Activexsite * psite;
Psite = caxwindowlesshost <cmaindlg>: getcontrolsite (idc_wmp11); // obtain the Meida player sub-control
If (psite! = NULL)
{
Psite-> setallowresize (false); // automatic resizing is not allowed
Ccomqiptr <iwmpcore> WMP = psite-> activexcontrol ();
Ccomqiptr <iwmpplayer4> wmp4 = psite-> activexcontrol ();
// This can be done manually as well
If (wmp4)
{
HR = wmp4-> put_windowlessvideo (variant_true); // No window mode
// HR = wmp4-> put_uimode (ccombstr ("full"); // fill Mode
}
// HR = WMP-> put_url (ccombstr ("C :\\ Temp \ videofile. wmv"); // multimedia file address
}

Return true;
}

Lresult cmaindlg: onbnclickedbtnbrowse (word/* wnotifycode */, word/* WID */, hwnd/* hwndctl */, bool &/* bhandled */)
{// Select a multimedia file
Static lpctstr pszfilter = _ T ("video files (*. avi ;*. MPG ;*. WMV) \ 0 *. avi ;*. MPG ;*. WMV \ 0 \ 0 ");
Cfiledialog fileopen (true, _ T ("Avi"), null,
Ofn_hidereadonly | ofn_overwriteprompt, pszfilter/*, m_hwnd */);
If (idok = fileopen. domodal ())
{
Activexsite * psite;
Psite = caxwindowlesshost <cmaindlg>: getcontrolsite (idc_wmp11 );
Setdlgitemtext (idc_txt_filename, fileopen. m_szfilename );
Ccomqiptr <iwmpplayer4> wmp4 = psite-> activexcontrol ();
Wmp4-> close ();
Wmp4-> put_url (ccombstr (fileopen. m_szfilename ));
}

Return 0;
}

 UseSliverlightAs a child Control

The main code is as follows:

Lresult cmaindlg: oninitdialog (uint/* umsg */, wparam/* wparam */, lparam/* lparam */, bool &/* bhandled */)
{
// Center the dialog on the screen
Centerwindow ();

// Set icons
Hicon = (hicon): LoadImage (_ module. getresourceinstance (), makeintresource (idr_mainframe ),
Image_icon,: getsystemmetrics (sm_cxicon),: getsystemmetrics (sm_cyicon), lr_defaultcolor );
Seticon (hicon, true );
Hicon hiconsmall = (hicon): LoadImage (_ module. getresourceinstance (), makeintresource (idr_mainframe ),
Image_icon,: getsystemmetrics (sm_cxsmicon),: getsystemmetrics (sm_cysmicon), lr_defaultcolor );
Seticon (hiconsmall, false );

// Initialize Silverlight control (this is not windowless but cool anyway)
Hresult hr;
Activexsite * psite;
Psite = caxwindowlesshost <cmaindlg>: getcontrolsite (idc_agcontrol1); // obtain the sliverlight subcontrol
If (psite! = NULL)
{
// Disable right-click!
Psite-> setallowrclick (false); // right-click Disabled
// Load from URL
// Ccombstr bstrurl ("file: // C: \ temp \ sortthefootbars. xap ");
Ccombstr bstrurl ("http://www.andybeaulieu.com/silverlight/2.0/sortthefoobars/ClientBin/SortTheFoobars.xap ");
Psite-> seturl (bstrurl); // sets the multimedia source file
Ccomqiptr <ixcpcontrol2> slight = psite-> activexcontrol ();
HR = slight-> put_source (bstrurl );
}
Return true;
}
