in my application,i just wanna open a url contain media,e.g. http://www.test.com/test.mp3,or rstp://www.test.com/test.3gp,so i need the symbian embeded media player's uid to open it.
This is what I use for showing links:
_LIT( KTestUrlPrefix,"4 " );
HBufC* parameter = HBufC::NewLC( KTestUrlPrefix().Length() + aLink.Length() );
parameter->Des().Copy( KTestUrlPrefix );
parameter->Des().Append( aLink );
if(iLauncher)
{
delete iLauncher;
iLauncher = NULL;
}
iLauncher = CBrowserLauncher::NewL();
iLauncher->LaunchBrowserEmbeddedL( *parameter, NULL, NULL, iOverriddenSettings );
CleanupStack::PopAndDestroy();
_LOGENTRY("web ad->");
If you know the content type of the URL, you can discover the UID of the right application and launch it as detailed here.
There are other alternatives:
CVideoPlayerUtility and CAudioPlayerUtility. Both have OpenUrl() methods.
Use the streaming classes directly (CMdaAudioOutStream and friends)
.. and there are other methods too.
That all said, if you are targeting Symbian^3 onwards, you might be better off developing in QT - Symbian C++ can very much considered 'deprecated' for app development.

I am currently trying to piece together a shader-based music visualizer. The plan is to read data from the current MMDevice, which I'm trying to follow the documentation for, but I must be doing something wrong because I had to jump through all sorts of hoops to get even just the MMDeviceEnumerator to compile.
In order for the uuids of MMDeviceEnumerator and IMMDeviceEnumerator to be defined, I had to set #define WINAPI_FAMILY WINAPI_FAMILY_GAMES. This was also required for EDataFlow and ERole enumerations to be defined. My first question is if I've missed some configuration somewhere, or if this is the intended method of enabling these things.
Currently, I have the following code in an AudioStream class:
class AudioStream {
public:
AudioStream() {
//SUCCEEDING(CoInitializeEx(nullptr, COINIT_MULTITHREADED));
SUCCEEDING(CoCreateInstance(
__uuidof(IMMDeviceEnumerator),
NULL,
CLSCTX_ALL,
__uuidof(MMDeviceEnumerator),
(void**)&this->mmDeviceEnumerator));
SUCCEEDING(this->mmDeviceEnumerator->GetDefaultAudioEndpoint(
eRender,
eConsole,
&this->mmDevice));
}
private:
IAudioClient* audioClient = NULL;
IAudioCaptureClient* captureClient = NULL;
IMMDeviceEnumerator* mmDeviceEnumerator = NULL;
IMMDevice* mmDevice = NULL;
};
If you're familiar with what the DirectX 12 project template looks like, this object is being instantiated in the Sample3DSceneRenderer constructor. The main issue I'm having right now is the following two errors which are immediately raised during startup:
onecore\com\combase\dcomrem\resolver.cxx(2299)\combase.dll!75AA0DFF: (caller: 75B1CF2C) ReturnHr(1) tid(42a8) 80040154 Class not registered
onecore\com\combase\dcomrem\resolver.cxx(2507)\combase.dll!75B1CF4D: (caller: 75AA29E4) ReturnHr(2) tid(42a8) 80040154 Class not registered
This causes the entire app to hang, and the project template visualization to never appear (the succeeding macro exits). Does anyone have any idea why this is failing? It must have to be something with the CoCreateInstance call :(
You are writing a Universal Windows Platform (UWP) app because that's what the "built-in" DirectX 12 App project template creates in Visual Studio. UWPs do not have access to all the same APIs and IMMDevice is not part of the UWP API surface area.
The fact that you defined WINAPI_FAMILY_GAMES means you hacked the API Family Partition macros which will define the API in a UWP context, but it doesn't mean that API actually works from the AppContainer process that all UWPs run in.
You really have two options:
(1) If you want to write a UWP, then you will need to enumerate audio devices via the proper Windows Runtime APIs which are in the Windows::Devices::Enumeration namespace.
Assuming you are using C++/CX language extensions (instead of the more modern C++/WinRT projections), then this code works:
auto operation = DeviceInformation::FindAllAsync(DeviceClass::AudioRender);
while (operation->Status == Windows::Foundation::AsyncStatus::Started)
{
Sleep(100);
}
if (operation->Status != Windows::Foundation::AsyncStatus::Completed)
{
throw std::runtime_error("FindAllAsync");
}
DeviceInformationCollection^ devices = operation->GetResults();
for (unsigned i = 0; i < devices->Size; ++i)
{
using Windows::Devices::Enumeration::DeviceInformation;
DeviceInformation^ d = devices->GetAt(i);
// d->Id->Data();
// d->Name->Data();
}
Also, if you want to get access to the audio capture device from a UWP, you must add a capability to your manifest to request it via <DeviceCapability Name="microphone"/>. See Microsoft Docs.
You should take the time to read the Microsoft Docs on UWPs so you have a better idea of what's supported and what's not.
(2) If you want to write a Win32 desktop app, use the directx-vs-templates instead which include DirectX 12 starting templates for Win32 desktop apps (plus alternative DirectX templates for UWP if that's your thing).
Whichever appmodel you use, you may want to take a look at DirectX Tool Kit for Audio.
BTW, WINAPI_FAMILY_GAMES is used by the Microsoft GDK for Xbox which is for writing titles for Xbox One and Xbox Series X|S. It uses Win32 APIs and doesn't use Windows Runtime APIs, so it has the IMMDevice interface in it's API surface. See Microsoft Docs.
I'm trying to package some of my MFC applications as Windows 10 apps using Desktop Bridge.
I am having no end of trouble getting my HTML help file (CHM) included and working with the installed program (new versions of VS don't include the help file, and using workaround to include that file results in a file that I don't have the rights to access).
So it makes me wonder about hosting the online help on my website. A couple of the issues that arise is how best to host multiple help topics, and how to override (on a application-wide basis) the behavior of accessing help topics. (My app is dialog-based.)
So I just wondered if anyone else has done this already. I'd be curious to review how these issues were addressed. I was not able to find anything online.
I do host my html help in a single document, using html anchors to get to the topic of interest. If you have multiple pages, adapt MyHelp accordingly.
I didn't actually use the Desktop Bridge but wondered if you have tried something like this:
BOOL CMyDialog::OnHelpInfo(HELPINFO* pHelpInfo)
{
MyHelp(_T("HIDD_MYDIALOG")); // HTML anchor goes here
return CDialog::OnHelpInfo(pHelpInfo);
}
...
// a global helper function for showing help
void MyHelp(LPCTSTR anchor)
{
extern CMyApp theApp;
TCHAR *cp, buffer[1000];
// look for the html document in the program directory
strcpy(buffer, _T("file:///"));
DWORD dw = GetModuleFileName(theApp.m_hInstance, buffer + strlen(buffer), sizeof(buffer));
if (cp = strrchr(buffer, '\\'))
{
strcpy(cp+1, _T("MyHelpDocument.htm#"));
strcat(cp+1, anchor);
// for some reason, I don't want the default browser to open, just the Internet Explorer
ShellExecute(NULL, _T("open"), _T("iexplore"), buffer, NULL, SW_SHOWNORMAL);
// or, for real online help, use just '_T("http://myurl.com/myonlinehelpdocument.html#") + anchor'
// instead of 'buffer' and ommit all before ShellExecute()
}
}
I'm not sure if ShellExecute will behave the way it used to in the shop app though. But certainly there will be a way to open a URL somehow. You might want to try if the Internet Explorer ActiveX works to display your help pages inside the app.
How do we make our application start on computer startup (and of course, after the user had signed in)?
And no, I am not making a virus.
Does registry editing sound like a good idea?
My OS is Windows 8.
However, I will try to make my application available for all possible Window OS.
The correct way to do this is simply to add a shortcut to your application's executable to the user's Startup folder. You do not need to (and should not) modify the registry.
Advanced users know how to do this manually already, but it may also be an option you want to provide as part of your installer and/or a configuration dialog in your application.
To do this from C++ code, you will need to do two things:
Retrieve the location of the current user's Startup folder.
This is accomplished by calling the SHGetKnownFolderPath function and specifying the KNOWNFOLDERID of the folder you're interested in. In this case, that would be FOLDERID_Startup.
Sample code:
std::wstring GetStartupFolderPath()
{
PWSTR pszPath;
HRESULT hr = SHGetKnownFolderPath(&FOLDERID_Startup,
0, // no special options required
NULL, // no access token required
&pszPath);
if (SUCCEEDED(hr))
{
// The function succeeded, so copy the returned path to a
// C++ string, free the memory allocated by the function,
// and return the path string.
std::wstring path(pszPath);
CoTaskMemFree(static_cast<LPVOID>(pszPath));
return path;
}
else
{
// The function failed, so handle the error.
// ...
// You might want to throw an exception, or just return an
// empty string here.
throw std::runtime_error("The SHGetKnownFolderPath function failed");
}
}
Note, however, that while SHGetKnownFolderPath is the recommended function to use, it is supported only by Windows Vista and later. If you need to support older versions of the operating system, you'll need to call it dynamically on newer versions where it is available, and otherwise fall back to calling the SHGetFolderPath function. This one takes a different type of identifier, a CSIDL value. The one you want is CSIDL_STARTUP.
Create a shortcut to your application's executable.
This is accomplished using a different set of Shell API functions. I won't bother writing up sample code here because it's all quite well explained on MSDN already: Shell Links
Now you just connect the dots: when you create the shortcut to your application's executable, specify the user's Startup folder as its destination path.
The only other thing to be aware of is that there are actually multiple Startup folders. Each user has one, which is the one we retrieved above using FOLDERID_Startup. About 99% of the time, that's the one you want. Putting a shortcut to your app there will cause it to be launched automatically when that user logs on.
However, there is also a global Startup folder that is shared by all users. This one is identified by FOLDERID_CommonStartup (or CSIDL_COMMON_STARTUP) and requires administrative privileges to add items to. That makes sense, of course, because whatever you put in there is going to launch automatically when any user logs on to the computer. Only administrators can affect global behavior like this. And chances are, your app doesn't need this anyway.
Start menu
Simplest solution is to place .lnk of .bat file into the Start Menu\On startup folder. This is easiest and not too sneaky against the user.
Registry:
Another solution is creating the key in the registry keys:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run] //All users
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce] //All users once
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run] //Currend user
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce] //Current user once
This is not that transparent - so a bit more agressive against the user.
On windows you can put a shortcut to your application in the Startup folder, or you can implement it as a service.
And that "I am not making a virus" does make you sound guilty... Maybe it is a keylogger? ;)
There are a lot of ways, but they all depend on your OS. For windows take a look at the "Task Schedualer" under "Administrative tools" in the control panel.
Maybe something like this? Note, this code snippet is not written by me.
#include <windows.h>
void Reg() {
::HKEY Handle_Key = 0;
::DWORD Dispoition = 0;
::RegOpenKeyEx( HKEY_LOCAL_MACHINE,
"Software\\Microsoft\\Windows\\CurrentVersion\\Run",
0,
KEY_ALL_ACCESS,
&Handle_Key );
const unsigned char Path[ MAX_PATH ] = "C:\\Windows\\YourProgramName.exe";
::RegSetValueEx( Handle_Key, "My Directory", 0, 1, Path, sizeof( unsigned char ) );
};
What do you guys think?
I'm trying to write a Windows Explorer thumbnail handler for our custom file type. I've got this working fine for the preview pane, but am having trouble getting it to work for the thumbnails.
Windows doesn't even seem to be trying to call the DllGetClassObject entry point.
Before I continue, note that I'm using Windows 7 and unmanaged C++.
I've registered the following values in the registry:
HKCR\CLSID\<my guid>
HKCR\CLSID\<my guid>\InprocServer32 (default value = path to my DLL)
HKCR\CLSID\<my guid>\InprocServer32\ThreadingModel (value = "Apartment")
HKCR\.<my ext>\shellex\{E357FCCD-A995-4576-B01F-234630154E96} (value = my guid)
I've also tried using the Win SDK sample, and that doesn't work. And also the sample project in this article (http://www.codemonkeycodes.com/2010/01/11/ithumbnailprovider-re-visited/), and that doesn't work.
I'm new to shell programming, so not really sure the best way of debugging this. I've tried attaching the debugger to explorer.exe, but that doesn't seem to work (breakpoints get disabled, and none of my OutputDebugStrings get displayed in the output window). Note that I tried setting the "DesktopProcess" in the registry as described in the WinSDK docs for debugging the shell, but I'm still only seeing one explorer.exe in the task manager - so that "may" be why I can't debug it??
Any help with this would be greatly appreciated!
Regards,
Dan.
I stumbled across this since you mentioned my blog ( codemonkeycodes.com ).
What problem are you having with my sample? Did you register you DLL using regsvr32? What version of Windows 7 are you on, 32 or 64?
Update:
I can't say what is or isn't working for you. I just downloaded the sample from my site, followed the directions and change the function
STDMETHODIMP CThumbnailProvider::GetThumbnail... to look like
{
*phbmp = NULL;
*pdwAlpha = WTSAT_UNKNOWN;
ULONG_PTR token;
GdiplusStartupInput input;
if (Ok == GdiplusStartup(&token, &input, NULL))
{
//gcImage.LogBuffer();
Bitmap * pBitmap = new Bitmap(188, 141);
if( pBitmap )
{
Color color(0, 0, 0);
pBitmap->GetHBITMAP(color, phbmp);
}
}
GdiplusShutdown(token);
if( *phbmp != NULL )
return NOERROR;
return E_NOTIMPL;
}
I registered the DLL and then created a new file with the proper extension, and tada, I had a nice black thumbnail.
I wish I could help you. Maybe you want to email me your code?
I've exactly the same problem. I cant make SDK or any sample works. I need COM sample because I must call Microsoft.Jet.OLEDB.4.0 which works only on 32 bits system.
I couldnt make this work: link
This works if AnyCPU is specified when compiling. Cant make it works for x86: link
This was nice under XP works like a charm: link
This show Adobe had problems with thumbnail An MS with Office 2007 (32 bits): link
Well as the topic says, I want to know if there is a tool or a tutorial that can help me access IE, get in a certain URL, do some action on that website. So I would have a program to do that for me instead of doing it myself every time.
Here is a project on Internet Explorer automation with C++
you should really rephrase your question.. you said what you want to do is login to hotmail programatically, check the pidgin code, they do it.
Documentation found here , here and you can I think navigate through the code and tutorials at will until you have your understanding of how the pidgin contributors did it.
You can find the main page for pidgin here
Code sample to get you started:
00362 static void
00363 msn_show_hotmail_inbox(PurplePluginAction *action)
00364 {
00365 PurpleConnection *gc;
00366 MsnSession *session;
00367
00368 gc = (PurpleConnection *) action->context;
00369 session = gc->proto_data;
00370
00371 if (session->passport_info.file == NULL)
00372 {
00373 purple_notify_error(gc, NULL,
00374 _("This Hotmail account may not be active."), NULL);
00375 return;
00376 }
00377
00378 purple_notify_uri(gc, session->passport_info.file);
00379 }
00652 void *
00653 purple_notify_uri(void *handle, const char *uri)
00654 {
00655 PurpleNotifyUiOps *ops;
00656
00657 g_return_val_if_fail(uri != NULL, NULL);
00658
00659 ops = purple_notify_get_ui_ops();
00660
00661 if (ops != NULL && ops->notify_uri != NULL) {
00662
00663 void *ui_handle = ops->notify_uri(uri);
00664
00665 if (ui_handle != NULL) {
00666
00667 PurpleNotifyInfo *info = g_new0(PurpleNotifyInfo, 1);
00668 info->type = PURPLE_NOTIFY_URI;
00669 info->handle = handle;
00670 info->ui_handle = ui_handle;
00671
00672 handles = g_list_append(handles, info);
00673
00674 return info->ui_handle;
00675 }
00676 }
00677
00678 return NULL;
00679 }
Rather than using IE for such things, look into appropriate screen scraping libraries for your language of choice. You can google and search Stack Overflow to find many such libraries. From here, you'll use your language's web APIs to send data to the server.
Don't know of any tool.
I use an embedded browser for such things. It is possible to connect to a running instance of IE. See
Connect to Running Instance of IE
Once you get an instance of IWebBrowser2, the coding is the same.
1. Get the Document Interface
pWebBrowser->Document->QueryInterface(
IID_IHTMLDocument2,(LPVOID*)&Doc);
2. Get all the elements on the Document
Doc->get_all(&Elements);
3. enum the Elements
Elements->get_length(&ulLen);
for_each
Elements->item(item, index, &ppvElement);
4. Detemine what element is desired.
* by classname
* by ID etc.. here I used the classname
ppvElement->get_className (&bstrElement);
5. Insert Text for user / password
ppvElement->put_innerText(wsUreser_or_Psswd)
6. Find the Sign in button and click it.
ppvElement->Click();
Your results may vary.

Why don't you make a feed in dapper in two minutes? Apparently some people have already done it as well.
