I am creating a small window form application which will return list of videos based on query. I am using this link https://developers.google.com/youtube/v3/code_samples/dotnet Everything is working fine except for the issue that if embedding is disabled by owner of some video then I am getting an error while trying to play the video that:
"Watch this video on youtube. Playback on other websites has been disabled by the video onwer".
So now I have two questions
1) Is there any way to play that video?
2) IF anwser of the first question is no then how can I filter those videos whose embedding has been disabled by it's owner. Means I don't want to add those videos in my list.
Thanks.
According to official documentation every video has status.embeddable property, which you can check in your code.
The status.embedabble, regardless of language used, is a response anytime one of the methods used in Videos reference is successfully called.
So I would suggest using the method list for example. To demonstrate, I place a youtube video in this videos.list Try-it and place "status" as part parameter.
And true enough I get the embedabble status:
"items": [
{
"kind": "youtube#video",
"etag": "\"7991kDR-QPaa9r0pePmDjBEa2h8/7NFYOO88j54fU9aKM8MsjN4zPro\"",
"id": "kIBdpFJyFkc",
"status": {
"uploadStatus": "processed",
"privacyStatus": "public",
"license": "youtube",
"embeddable": true,
"publicStatsViewable": true
}
}
]
Thanks for all the answers. After exploring the documentation I finally found the solution to filter those videos whose embedding is disabled by the owner.
There is VideoEmbeddable property of YoutubeService.Search.List method which expects Google.Apis.YouTube.v3.SearchResource.ListRequest.VideoEmbeddableEnum can do the trick.
var searchListRequest = youtubeService.Search.List("snippet");
searchListRequest.Q = ""; // Replace with your search term.
searchListRequest.MaxResults = 50;
searchListRequest.Type = "video";
searchListRequest.VideoEmbeddable = SearchResource.ListRequest.VideoEmbeddableEnum.True__;
Specifying a type "video" only returns video insteal of all videos, playlists and channels.

I have an issue. I want to get radio-name through the C# api for winbox. In winboxs terminal works :put [/interface wireless get [/interface wireless find default-name=wlan1] radio-name] command, but not in C# api. I rode that, in api i can't uses [ ] marks, but i dont know how it write without it. I tried like this:
mikrotik.Send("/put ", true);
mikrotik.Send(".system identity get name", true);
foreach (string h in mikrotik.Read())
{
mkResult += h;
}
l_identify.Text = mkResult;
but its doesn't work. Everytime i get this:
!trap=category=0=message=no such command or directiory (put [)!trap=message=no such command prefix!done
Please help :<
PS: Sorry for my English :P
You are sending incorrect commands to the device.
You need to use this:
/interface/wireless/print
=.proplist=radio-name
?default-name=wlan1
.proplist contains list of fields to be returned, ?default-name=wlan1 is a condifion for filtering.
You can find more about Mikrotik API syntax in the official Wiki.
The question says it all.
I would like to create the simplest possible VU-meter example, using the new UWP Media Graph API, but so far, I haven't found any good examples.
There are a couple of questions in this:
I am using the "normal" code to enumerate my microphones:
var deviceInformation = await DeviceInformation.FindAllAsync(MediaDevice.GetAudioCaptureSelector());
However, when I create an AudioGraphSettings object, I cannot find a property to pass the device found. There is a property named DesiredRenderDeviceAudioProcessing however, I'm not sure I understand it's purpose.
Following the best examples I've found, I proceed to create a graph, and use that to get an InputNode as such:
var creationResult = await AudioGraph.CreateAsync(settings);
if (creationResult.Status != AudioGraphCreationStatus.Success)
return;
_graph = creationResult.Graph;
var inputNodeCreationResult = await _graph.CreateDeviceInputNodeAsync(Windows.Media.Capture.MediaCategory.Media);
if (inputNodeCreationResult.Status != AudioDeviceNodeCreationStatus.Success)
{
DestroyGraph();
return;
}
_inputNode = inputNodeCreationResult.DeviceInputNode;
From here on, I'm running blind. Not finding any good tutorials, examples or documentation to help me.
I am only interested in sound level (dB), not the waveform. Is there anyone that can help me complete this, or point me to some decent documentation?
"Scenario 2: Device Capture" from the Windows Universal Samples - Audio Creation project should provide some guidance. From your code it looks like you're on track. Might just be a case of adding the following:
_frameOutputNode = _graph.CreateFrameOutputNode();
_frameOutputNode.Start();
_graph.QuantumProcessed += Graph_QuantumProcessed;
_graph.Start();
And using the Graph_QuantumProcessed callback to analyse the AudioFrame provided by a call to _frameOutputNode.GetFrame().
Hope it helps.
Since Vista, Windows is shipped with WIA 2.0 (wiaaut.dll).
According to the following KB article and many of my findings on various forums, duplex scanning is no longer possible using WIA 2.0. Yet, the article mentions the use of native WIA 2.0, what would make duplex scanning possible.
(https://support.microsoft.com/en-us/kb/2709992)
According to the WIA 2.0 documentation (https://msdn.microsoft.com/en-us/library/windows/desktop/ms630196(v=vs.85).aspx), duplex scanning is possible but using the new WIA_IPS_DOCUMENT_HANDLING_SELECT (3088) property.
My issues are:
I have no idea how to use native WIA, I suspect when using C# its just not possible.
I cant find a way to set the new WIA_IPS_DOCUMENT_HANDLING_SELECT property, as the property is not present in my wiaDevice properties. According to WiaDef.h, its property id is still 3088 and the only possible value is 0x400 (1024).
If anyone could help me (and I think many others) out on this, it would be much appreciated!
Greetings,
M.
After a few more hours of searching I found a clue in the following post.
https://stackoverflow.com/a/7580686/3641369
As I used a one-pass duplex scanner, both front and back sides where scanned at the same time. By setting the device properties (device properties, not item properties) Document_Handling_Select to 5 (Feeder + Duplex) and Pages to 1 and calling the transfer method 2 times, I finally got the font and back side of the scan.
Setting wiaDev.Properties["Document Handling Select"] = 5 specifies the use of the feeder and scanning duplex.
Setting wiaDev.Properties["Pages"] = 1 specifies that the scanner should keep 1 page in memory, this allowing to keep both front side and back side of the page in memory during 1 scan pass.
if (duplex)
{
wiaDev.Properties["Document Handling Select"].set_Value(5);
wiaDev.Properties["Pages"].set_Value(1);
}
Getting the Wia item and setting item properties such as color and dpi.
var item = wiaDev.Items[1];
item.Properties["6146"].set_Value((int)clr);
item.Properties["6147"].set_Value(dpi);
item.Properties["6148"].set_Value(dpi);
Then calling the transfer method twice returns two different images
var img = (ImageFile)wiaCommonDialog.ShowTransfer(item, FormatID.wiaFormatJPEG);
ImageFile imgduplex = null;
if(duplex)
imgduplex = (ImageFile)wiaCommonDialog.ShowTransfer(item, FormatID.wiaFormatJPEG);
Hope this helps someone!
I am creating an application that interfaces with Google's Maps API v3. My current approach is using a WebBrowser control by WebBrowser.Navigate("Map.html"). This is working correctly at the moment; however, I am also aware of WebBrowser.InvokeScript(). I have seen this used to execute a javascript function, but I would like to have something like the following structure:
APICalls.js - Contains different functions that can be called, or even separated out into a file for each function if necessary.
MapInterface.cs
WebBrowser.InvokeScript("APICalls.js", args) - Or control the javascript variables directly.
I have seen the InvokeScript method used, but none of the examples gave any detail to the source of the function, so I'm not sure if it was calling it from an html file or js file. Is it possible to have a structure like this, or a similarly organized structure, rather than creating an html file with javascript in each one and using Navigate()?
Additionally, are there any easier ways to use Google Maps with WPF. I checked around, but all of the resources I found were at least 2-3 years old, which I believe is older than the newest version of the maps API.
I can't suggest a better way of using Google Maps API with WPF (although I'm sure it exists), but I can try to answer the rest of the question.
First, make sure to enable FEATURE_BROWSER_EMULATION for your WebBrowser app, so Google Maps API recognizes is it as modern HTML5-capable browser.
Then, navigate to your "Map.html" page and let it finish loading. Here's how it can be done using async/await (the code is for the WinForms version of WebBrowser control, but the concept remains the same).
You can have your APICalls.js as a separate local file, but you'd need to create and populate a <script> element for it from C#. You do it once for the session.
Example:
var scriptText = File.ReadAllText("APICalls.js");
dynamic htmlDocument = webBrowser.Document;
var script = htmlDocument.createElement("script");
script.type = "text/javascript";
script.appendChild(htmlDocument.createTextNode(scriptText));
htmlDocument.body.appendChild(script);
Then you can call functions from this script in a few different ways.
For example, your JavaScript entry point function in APICalls.js may look like this:
(function() {
window.callMeFromCsharp = function(arg1, arg2) {
window.alert(arg1 + ", " +arg2);
}
})();
Which you could call from C# like this:
webBrowser.InvokeScript("callMeFromCsharp", "Hello", "World!");
[UPDATE] If you're looking for a bit more modular or object-oriented approach, you can utilize the dynamic feature of C#. Example:
JavaScript:
(function() {
window.apiObject = function() {
return {
property: "I'm a property",
Method1: function(arg) { alert("I'm method 1, " + arg); },
Method2: function() { return "I'm method 2"; }
};
}
})();
C#:
dynamic apiObject = webBrowser.InvokeScript("apiObject");
string property = apiObject.property;
MessageBox.Show(property);
apiObject.Method1("Hello!");
MessageBox.Show(apiObject.Method2());
I'm looking for help from anyone who's worked with the verbot sdk.
I'm making a program that I want to use the LearnedKnowledge.vkb, Teacher.vkb, and any standard bot (julia, for example). Those who've used this before will know that with the rules in Teacher, you can essentially write responses to things that the bot doesn't understand, and train it on the fly.
I'm planning on using speech recognition and text-to-speech, but my problem right now is that after I load the knowledgebases, I can't seem to get any response from the bot.
Here's what I have: The Verbot5Library.dll, from verbots.sourceforge.net (I got the editor and player too, to make sure the files were working). In my program, I set up the variables as such:
Verbot5Engine verbot = new Verbot5Engine();
KnowledgeBase kb = new KnowledgeBase();
KnowledgeBaseItem kbi = new KnowledgeBaseItem();
State state = new State();
XMLToolbox xmlToolboxKB = new XMLToolbox(typeof(KnowledgeBase));
Then I initialize the verbot engine and load the kbs:
// using the xmlToolboxKB method I saw in this forum: http://www.verbots.com/forums/viewtopic.php?t=2984
kbi.Fullpath = #"C:\\[full path to kb...]\\";
kbi.Filename = "LearnedKnowledge.vkb";
kb = (KnowledgeBase)xmlToolboxKB.LoadXML(kbi.Fullpath + kbi.Filename);
verbot.AddKnowledgeBase(kb, kbi);
kbi.Filename = "julia.vkb";
kb = (KnowledgeBase)xmlToolboxKB.LoadXML(kbi.Fullpath + kbi.Filename);
verbot.AddKnowledgeBase(kb, kbi);
//trying to use LoadKnowledgeBase and LoadCompiledKnowledgeBase methods: verbot.LoadKnowledgeBase("C:\\[full path to kb...]\\LearnedKnowledge.vkb");
//verbot.LoadCompiledKnowledgeBase("C:\\[full path...]\\julia.ckb");
//verbot.LoadCompiledKnowledgeBase("C:\\[full path...]\\Teacher.ckb");
// set up state
state.CurrentKBs.Add("C:\\[full path...]\\LearnedKnowledge.vkb");
state.CurrentKBs.Add("C:\\[full path...]\\Teacher.vkb");
state.CurrentKBs.Add("C:\\[full path...]\\julia.ckb");
Finally, I attempt to get a response from the verbot engine:
Reply reply = verbot.GetReply("hello", state);
if (reply != null)
Console.WriteLine(reply.AgentText);
else
Console.WriteLine("No reply found.");
I know julia has a response for "hello", as I've tested it with the editor. But all it ever returns is "No reply found". This code has been taken from the example console program in the SDK download (as very little documentation is available). That's why I need some pointers from someone who's familiar with the SDK.
Am I not loading the KBs correctly? Do they all need to be compiled (.ckb) instead of the XML files (.vkb)? I've used the verbot.OnKnowledgeBaseLoadError event handler and I get no errors. I even removed the resource file Default.vsn needed to load the Teacher, and it throws an error when trying to load it so I'm pretty sure it's all loading correctly. So why do I always get "No reply found"?
