I am working on a webkit-kernel-browser plugin.
Most plugin obey the rules of NPAPI.
After call the NP_new function,the browser should call the Npp_setwindows and etc.
But the chrome browser does not run this .
It call the Np_destory to finished the instance straightly.
So I can not get the browser 's xid to set the videosink on it .
How can work it out?
And when I use the firefox browser, I can get the xid.
Unfortunately ,When I use the gst_x_overlay_set_xwindow_id to embed to the browser .
The browser crashed.
Here is some code for test.
gst_init (NULL, NULL);
player->pipeline = gst_element_factory_make ("playbin2", "playstation");
LOGMSG("create playbin2");
player->audio_sink = gst_element_factory_make ("alsasink", "audio-sink");
if (NULL == player->audio_sink)
{
player->audio_sink = gst_element_factory_make ("autoaudiosink", "audio-sink");
g_warning ("Could not create a GST audio_sink. Audio unavailable.");
}
player->video_sink = gst_element_factory_make ("xvimagesink", "video-sink");
if (NULL == player->video_sink)
{
//pvrvideosink is used for some special solution ,but this case never used
player->video_sink = gst_element_factory_make ("pvrvideosink","video-sink");
g_warning ("Could not create a GST video_sink. Video unavailable.");
}
g_object_set (player->video_sink, "force-aspect-ratio", TRUE, NULL);
sprintf(buff," \n pipleline:%p\n video:%p\n audio:%p\n uri:%s\n xid:%d",
player->pipeline,player->video_sink,player->audio_sink,player->uri,player->xid);
LOGMSG(buff);enter code here
// log shows all the content is ok
g_object_set (player->pipeline, "video-sink", player->video_sink, NULL);
g_object_set (player->pipeline, "audio-sink", player->audio_sink, NULL);
g_object_set (player->pipeline, "uri",player->uri, NULL);
player->bus = gst_element_get_bus (GST_ELEMENT (player->pipeline));
gst_bus_add_watch(player->bus,(void *)process_events,player);
LOGMSG("start set winid");
/*
chrome can not get the browser xid ,so it display the image in fullscreen way with the player 's own window. The firefox can not display the image at all. It crashed here.
*/
if (player->xid != 0 )
{
gst_x_overlay_prepare_xwindow_id(GST_X_OVERLAY(GST_ELEMENT(player->video_sink)));
gst_x_overlay_set_xwindow_id(GST_X_OVERLAY(GST_ELEMENT(player->video_sink)),player->xid);
gboolean spt = gst_x_overlay_set_render_rectangle
(GST_X_OVERLAY(GST_ELEMENT(player->video_sink)),10,10,480,270);
if (!spt)
{
LOGMSG("not support the rectangle");
}
gst_x_overlay_expose(GST_X_OVERLAY(GST_ELEMENT(player->video_sink)));
}
LOGMSG("set xwinid finished");
gst_element_set_state(player->pipeline,GST_STATE_PLAYING);
loop = g_main_loop_new (NULL, FALSE);
LOGMSG("start player loop");
g_main_loop_run (loop);
Can anyone give me some information about these?
Best regards,

I work on an electron application, and we would like to support dragging and dropping .msg files from our app into Outlook (or the Windows shell, or wherever, but primarily Outlook). The files will not necessarily be available before the user starts the drag and drop operation, and will need to be downloaded once the user begins the drag and drop. This means we can't use electron's inbuilt startDrag as it requires that the files are already in the filesystem, so I have implemented a node c++ addon to handle it using the OLE Drag and Drop API.
The data extraction (from my app to Outlook) needs to occur asynchronously, otherwise node's event loop will be blocked, halting the download. This means that the data extraction has to occur on another thread so that the event loop can continue actually downloading the data (currently doing the download in c++ is not an option, it has to occur in node). So I have implemented IDataObjectAsyncCapability on my DataObject, to indicate that I support asynchronous data extraction (it would be even nicer to be able to indicate that I don't support synchronous), but Outlook won't even query for the Interface, let alone do the data extraction asynchronously. The Windows shell does however query for the interface, but after the call to GetData, it still performs the extraction synchronously inside DoDragDrop, without even invoking any of the IDataObjectAsyncCapability methods. Is there something lacking in my implementation, or a specific way to encourage the drop target to start up a new thread?
Here is the meat of my DataObject implementation, if there's anything else that could be of use, I can provide.
STDMETHODIMP DataObject::QueryInterface(REFIID iid, LPVOID* ppvObject) {
if (ppvObject == nullptr) {
return E_INVALIDARG;
} else if (iid == IID_IUnknown) {
AddRef();
*ppvObject = reinterpret_cast<LPUNKNOWN>(this);
return S_OK;
} else if (iid == IID_IDataObject) {
AddRef();
*ppvObject = reinterpret_cast<LPDATAOBJECT>(this);
return S_OK;
} else if (iid == IID_IDataObjectAsyncCapability) {
AddRef();
*ppvObject = reinterpret_cast<IDataObjectAsyncCapability*>(this);
return S_OK;
}
*ppvObject = nullptr;
return E_NOINTERFACE;
}
STDMETHODIMP DataObject::GetData(LPFORMATETC queryFormat,
LPSTGMEDIUM outputStorage) {
if (queryFormat->cfFormat == CF_FILEDESCRIPTOR &&
(queryFormat->tymed & TYMED_HGLOBAL) && queryFormat->lindex <= 0 &&
queryFormat->dwAspect == DVASPECT_CONTENT) {
outputStorage->tymed = TYMED_HGLOBAL;
outputStorage->pUnkForRelease = nullptr;
outputStorage->hGlobal =
lockAndDuplicateHGLOBAL(this->groupDescriptorStorage.hGlobal);
return S_OK;
} else if (queryFormat->cfFormat == CF_FILECONTENTS &&
(queryFormat->tymed & TYMED_ISTREAM) &&
queryFormat->dwAspect == DVASPECT_CONTENT &&
queryFormat->lindex >= 0 &&
queryFormat->lindex < this->files.size()) {
// files is vector<pair<FILEDESCRIPTOR, STGMEDIUM>>
// where the STGMEDIUM is set to IStream
// Am I doing something wrong here?
auto file = this->files[queryFormat->lindex].second;
*outputStorage = file;
return S_OK;
}
return DV_E_FORMATETC;
}
STDMETHODIMP DataObject::QueryGetData(LPFORMATETC queryFormat) {
if (queryFormat->cfFormat == CF_FILEDESCRIPTOR ||
(queryFormat->cfFormat == CF_FILECONTENTS &&
(queryFormat->tymed & TYMED_HGLOBAL))) {
return S_OK;
}
return DATA_E_FORMATETC;
}
STDMETHODIMP DataObject::EnumFormatEtc(DWORD dwDirection,
LPENUMFORMATETC* ppEnumFormatEtc) {
if (dwDirection == DATADIR_GET) {
// basic implementation of IEnumFormatEtc (not mine)
return EnumFormat::Create(this->supportedFormats, this->numFormats,
ppEnumFormatEtc);
}
return E_INVALIDARG;
}
// Do the actual drag drop
// files is a list of STGMEDIUMS with IStreams. I'm using data that's readily available while
// implementing this, could that be somehow interfering and causing this problem in the first place?
DWORD dwEffect;
auto dataObject = new DataObject(groupDescriptorStorage, files);
auto dropSource = new DropSource();
// Do these DROPEFFECTS have an effect?
auto result = DoDragDrop(dataObject, dropSource,
DROPEFFECT_COPY | DROPEFFECT_MOVE, &dwEffect);
// By the time we get here, the data extraction would already have occured
// because it's happening inside DoDragDrop. of course, isAsyncOperation will be false
BOOL isInAsyncOperation;
dataObject->InOperation(&isInAsyncOperation);
I've followed the instructions from here as well as various forum posts I've found, but I can't seem to find anything about what to do when the drop target doesn't play ball.
I'm really stuck for ideas as to how to make this work. If the drop target isn't even querying for IDataObjectAsyncCapability then is it hopeless? Should I be returning something other than the file contents when it's first requested?
If I open up a console prompt I can type this command:
start msedge "d:\HTML\Verticle Alignment.HTM"
It starts Microsoft Edge and opens the web page.
So I tried to do this programmatically in a test program using MFC:
void CMFCApplication8Dlg::OnBnClickedButton1()
{
ExecuteProgram(_T("start"), _T("msedge d:\\HTML\\Verticle Alignment.HTM"));
}
BOOL CMFCApplication8Dlg::ExecuteProgram(CString strProgram, CString strArguments)
{
SHELLEXECUTEINFO se = { 0 };
MSG sMessage;
DWORD dwResult;
se.cbSize = sizeof(se);
se.lpFile = strProgram;
se.lpParameters = strArguments;
se.nShow = SW_SHOWDEFAULT;
se.fMask = SEE_MASK_NOCLOSEPROCESS;
ShellExecuteEx(&se);
if (se.hProcess != nullptr)
{
do
{
dwResult = ::MsgWaitForMultipleObjects(1, &(se.hProcess), FALSE,
INFINITE, QS_ALLINPUT);
if (dwResult != WAIT_OBJECT_0)
{
while (PeekMessage(&sMessage, nullptr, NULL, NULL, PM_REMOVE))
{
TranslateMessage(&sMessage);
DispatchMessage(&sMessage);
}
}
} while ((dwResult != WAIT_OBJECT_0) && (dwResult != WAIT_FAILED));
CloseHandle(se.hProcess);
}
if ((DWORD_PTR)(se.hInstApp) < 33)
{
// Throw error
AfxThrowUserException();
return FALSE;
}
return TRUE;
}
But when I run it I get this error message:
So how can I launch my file in Microsoft Edge? I am using the latest Windows 10 so it is Microsoft Edge Chromium.
I have seen other questions which refer to making Edge the default browser and then just "opening" the data file and it working it all out but this is not OK in this case. In my editor I have a menu flyout which lists all the installed browsers (excluding Edge for now). But i want to add Edge so need to be able to programatically start it with my file to view.
Based on the comments provided to me, and to factor in for spaces in the file name, this works:
ExecuteProgram(_T("msedge"), _T("\"d:/HTML/Verticle Alignment.HTM\""));
The program to execute needs to be msedge and not start.
The parameter needs to be wrapped in " quotes.
var itemshop_idx = {
idle:1,
out:2,
in:3
};
spine_itemShop.state.onComplete = function (trackIndex) {
switch(trackIndex){
case itemshop_idx.in://in
spinePlay_1(spine_itemShop, "popup_item_shop_idle", itemshop_idx.idle, true);
break;
case itemshop_idx.out://out
group_itemShop.visible = false;
break;
}
};
spine_itemShop.setAnimationByName(itemshop_idx.in, "popup_item_shop_in", false);
this code show me "popup_item_shop_in" animation just once.
when I play
spine_itemShop.setAnimationByName(itemshop_idx.in, "popup_item_shop_in", false);
again, I don't show "popup_item_shop_in" animation.
Just be showed "popup_item_shop_idle" animation directly.
what a problem?
I have searched solution about this problem use a lot of keyword like
spine/phaser/animation/pixi.js/orange group/github/time/replay/reset/init/etc...
But I can't find solution.
I'm trying to add multiple (actually 3 ) views to an SDI application and give the user choose witch View will be load according to his choice :
IMG
I have followed this tutorial in the official MS documentation .
So, have created three classes : CAdminView CAssistantView CBiblioView and an authentication class associated to a dialog frame .
My Questions are :
1) how to edit this three view classes (Graphically) ?
2) at first time I want to show just the authentication dialog window , how to do that ?
* I tried to change m_pMainWnd->ShowWindow(SW_SHOW);
by m_pMainWnd->ShowWindow(SW_HIDE); but no expected result
3) I expect to load the view according to parameter, this is what I added to the InitInstance funnction :
CView* pActiveView = ((CFrameWnd*) m_pMainWnd)->GetActiveView();
m_BiblioView = (CView*) new CBiblioView;
m_AdminView = (CView*) new CAdminView;
m_AssistantView = (CView*) new CAssistantView;
CDocument* pCurrentDoc = ((CFrameWnd*)m_pMainWnd)->GetActiveDocument();
// Initialize a CCreateContext to point to the active document.
// With this context, the new view is added to the document
// when the view is created in CView::OnCreate().
CCreateContext newContext;
newContext.m_pNewViewClass = NULL;
newContext.m_pNewDocTemplate = NULL;
newContext.m_pLastView = NULL;
newContext.m_pCurrentFrame = NULL;
newContext.m_pCurrentDoc = pCurrentDoc;
// The ID of the initial active view is AFX_IDW_PANE_FIRST.
// Incrementing this value by one for additional views works
// in the standard document/view case but the technique cannot
// be extended for the CSplitterWnd case.
UINT viewID = AFX_IDW_PANE_FIRST + 1;
CRect rect(0, 0, 0, 0); // Gets resized later.
// Create the new view. In this example, the view persists for
// the life of the application. The application automatically
// deletes the view when the application is closed.
m_AdminView->Create(NULL, "Fenetre Administrarteur", WS_CHILD, rect, m_pMainWnd, viewID, &newContext);
m_AssistantView->Create(NULL, "Fenetre Assistant", WS_CHILD, rect, m_pMainWnd, viewID, &newContext);
m_BiblioView->Create(NULL, "Fenetre Bibliothecaire ", WS_CHILD, rect, m_pMainWnd, viewID, &newContext);
// When a document template creates a view, the WM_INITIALUPDATE
// message is sent automatically. However, this code must
// explicitly send the message, as follows.
m_AdminView->SendMessage(WM_INITIALUPDATE, 0, 0);
m_AssistantView->SendMessage(WM_INITIALUPDATE, 0, 0);
m_BiblioView->SendMessage(WM_INITIALUPDATE, 0, 0);
and this is my switch function :
CView* CMiniProjetApp::SwitchView(int Code ) //1 : Admi / 2 : Biblio / 3 : Assistant
{
CView* pActiveView =((CFrameWnd*) m_pMainWnd)->GetActiveView();
CView* pNewView= NULL;
switch(Code){
case 1 : pNewView= m_AdminView; break;
case 2 : pNewView= m_BiblioView; break;
case 3 : pNewView= m_AssistantView; break;
}
// Exchange view window IDs so RecalcLayout() works.
#ifndef _WIN32
UINT temp = ::GetWindowWord(pActiveView->m_hWnd, GWW_ID);
::SetWindowWord(pActiveView->m_hWnd, GWW_ID, ::GetWindowWord(pNewView->m_hWnd, GWW_ID));
::SetWindowWord(pNewView->m_hWnd, GWW_ID, temp);
#else
UINT temp = ::GetWindowLong(pActiveView->m_hWnd, GWL_ID);
::SetWindowLong(pActiveView->m_hWnd, GWL_ID, ::GetWindowLong(pNewView->m_hWnd, GWL_ID));
::SetWindowLong(pNewView->m_hWnd, GWL_ID, temp);
#endif
pActiveView->ShowWindow(SW_HIDE);
pNewView->ShowWindow(SW_SHOW);
((CFrameWnd*) m_pMainWnd)->SetActiveView(pNewView);
((CFrameWnd*) m_pMainWnd)->RecalcLayout();
pNewView->Invalidate();
return pActiveView;
}
Any errors notices ??!!
*please help me !
Thanks .
Showing and Hiding the window is the correct way. But you Need to set the view as active too.
You find the required working codein this MSDN Sample VSSWAP32.
The required code to switch and hide the other views is shown in the article.
I am writing a Chrome extension that saves/restores your browsers window state - So, I save the state of a given window:
var properties = [ "top",
"left",
"width",
"height",
"incognito",
"focused",
"type"
];
var json = {};
var cache = chrome_window_object;
// copy only the keys we care about:
_.each(properties,function(key,value) {
json[key] = cache[key];
});
// then copy the URLs of the tabs, if they exist:
if(cache.tabs) {
json.url = [];
_.each(cache.tabs,function(tab) {
json.url.push(tab.url);
});
}
return json;
At some point in the future, I remove all windows:
closeAllWindows: function(done_callback) {
function got_all(windows) {
var index = 0;
// use a closure to only close one window at a time:
function close_next() {
if(windows.length <= index) return;
var window = windows[index++];
chrome.windows.remove(window,close_next);
}
// start closing windows:
close_next();
}
chrome.windows.getAll(got_all);
}
and then I restore the window using:
chrome.windows.create(json_from_before);
The window that is created has an extra tab in it, whatever was in the window that I just closed... I am completely floored, and I assume the problem is something that I am doing in the code that I haven't posted (it's a big extension). I've spent a few hours checking code line by line and making sure I'm not explicitly asking for this tab to be created. So - has anybody seen anything like this before?
