If i execute NPN_Evaluate in plugin, when camera preview is running, the whole ui gets blocked and does not take any input from the user. My understanding was am doing NPN_Evaluate on a wrong NPObject which i get using NPN_GetValue( Npp, NPNVWindowNPObject, &sWindowObj). The script am trying to evaluate is like this:
"confirm (\'Do you want to Capture Image\');"
which shows a popup above camera preview asking to capture image.
ok guys... I found the problem. I was trying to evaluate the javascript from a native call from java to jni. when i changed the thread of execution, the problem was solved.

After login in Chrome browser, I am getting a save password popup from the browser. I want to handle that popup and want to close that using Robot Framework
Browse popup window
Thanks
This question has been asked and answered before with a pure Python context. This answer continues on this SO post for a working Robot Example.
The popup you see is generated by Chrome itself. It's not an HTML alert. For this reason none of the Selenium2Library keywords will have any effect on it. Nor wil settings cookies or javascript.
These settings can be manually set using the chrome://settings link. Go to advanced settings and then scroll down to Passwords and Forms. Untick the second item and this will prevent the popup.
To do the same automatically in Robot Framework the WebDriver needs to be started with additional preferences:
Chrome With Preferences
${chrome_options} = Evaluate sys.modules['selenium.webdriver'].ChromeOptions() sys, selenium.webdriver
${prefs} Create Dictionary credentials_enable_service=${false}
Call Method ${chrome_options} add_experimental_option prefs ${prefs}
Call Method ${chrome_options} add_argument --disable-infobars
Create WebDriver Chrome chrome_options=${chrome_options}
Go To https://secure.url.com
This key things here are credentials_enable_service=${false} where it is important to use ${false} and not false, as the latter is interpreted as a string and then added to Chrome as "false" instead of the correct value false.
The second item is that preferences are not added as arguments but through assigning a dictionary to the prefs property of the ChromeOptions() object like so: add_experimental_option prefs ${prefs}
I do not think this is real to be honest (as it's property of the browser.) Are you having issues with that? The only thing you can dismiss is javascript alert and probably the best way to handle this is:
${alert} = Get Alert Message dismiss=${dismiss}
I have this in my test teardown with Run Keyword and Ignore Error, it makes me able to fetch optional js alert content and debug (also dismisses it do the rest of the suite can be executed.)
Three Ways To do do it.
1) Many a times, Once pop-up appear on screen and Disappear a cookie is set which you can view in developer console-> application. If you set this cookie with value using Add Cookie keyword. Pop- up wont appear.
2) if first doesn't work, then open developer tools and monitor the local store from developer tools -> application and close the pop-up. U will notice some variable with a value is stored in local storage. You can set that value using your script and u wont see the pop-up while executing variable.
3) If first and second doesn't work, the pop-up is most likely linked to a javascript variable. set java script variable using Execute Javascript Keyword and your problem must be solved.
Talk with your dev team, to see which way will work for you.
In UI/Automation Testing using Xcode 7, is there a way to list all of the XCUIElements on an app screen? Like in a tree or list, or even something in the Xcode UI? I can record tests for the app under test using clicks, but when I go to run the test, it fails. It fails because it can't find the XCUIElements from the generated code.
You can view it in Xcode hierarchy debugger.
From Apple Docs:
To enter the view debugger, run your app in Xcode and click the Debug View Hierarchy button in the debug bar.
You can debug the state of UI element using,
XCUIElement.debugDescription
It returns a snapshot of UIView in html format with a nice look up into the UI elements state with properties like element type(e.g textField, button), traits like focussed, enabled and values e.g placeholderValue.
You can also use accessibilityInspector app to look into accessibility attributes for the UI Elements on the view and verify that elements have accessibility properties set correctly.
Another handy tool to investigate the view is new hierarchy viewer which can be invoked during recording from debug console toolbar or Debug Navigator filter when you enable breakpoint in your test code.
Xcode 7 also has a nice test reporting under Report Navigator which can help you drill down exact reason with the test failure. e.g
UI Test Activity:
Assertion Failure: Asynchronous wait failed: Exceeded timeout of 10 seconds, with unfulfilled expectations: "Expect predicate `exists == 1` for object "Logout" Button".
Hope this helps.
I'm trying to capture audio using WASAPI. My code is largely based on the ChatterBox VoIP sample app. I'm getting audio buffers, but they are all silent (flagged AUDCLNT_BUFFERFLAGS_SILENT).
I'm using Visual Studio Express 2012 for Windows Phone. Running on the emulator.
I had the exact same problem and managed to reproduce it in the ChatterBox sample app if I set Visual Studio to native debugging and at any point stepped through the code.
Also, closing the App without going through the "Stop" procedure and stopping the AudioClient will require you to restart the emulator/device before being able to capture audio data again.
It nearly drove me nuts before I figured out the before mentioned problems but I finally got it working.
So..
1. Be sure to NOT do native debugging
2. Always call IAudioClient->Stop(); before terminating the App.
3. Make sure you pass the correct parameters to IAudioClient->Initialize();
I've included a piece of code that works 100% of the time for me. I've left out error checking for clarity..
LPCWSTR pwstrDefaultCaptureDeviceId =
GetDefaultAudioCaptureId(AudioDeviceRole::Communications);
HRESULT hr = ActivateAudioInterface(pwstrDefaultCaptureDeviceId,
__uuidof(IAudioClient2), (void**)&m_pAudioClient);
hr = m_pAudioClient->GetMixFormat(&m_pwfx);
m_frameSizeInBytes = (m_pwfx->wBitsPerSample / 8) * m_pwfx->nChannels;
hr = m_pAudioClient->Initialize(AUDCLNT_SHAREMODE_SHARED,
AUDCLNT_STREAMFLAGS_NOPERSIST | AUDCLNT_STREAMFLAGS_EVENTCALLBACK,
latency * 10000, 0, m_pwfx, NULL);
hr = m_pAudioClient->SetEventHandle(m_hCaptureEvent);
hr = m_pAudioClient->GetService(__uuidof(IAudioCaptureClient),
(void**)&m_pCaptureClient);
And that's it.. Before calling this code I've started a worker thread that will listen to m_hCaptureEvent and call IAudioCaptureClient->GetBuffer(); whenever the capture event is triggered.
Of course using Microsoft.XNA.Audio.Microphone works fine to, but it's not always an option to reference the XNA framework.. :)
It was a really annoying problem which waste about 2 complete days of mine.My problem was solved by setting AudioClientProperties.eCatagory to AudioCategory_Communications instead of AudioCategory_Other.
After this long try and error period I am not sure that the problem won't repeat in the future because the API doesn't act very stable and every run may return a different result.
Edit:Yeah my guess was true.Restarting the wp emulator makes the buffer silent again.But changing the AudioClientProperties.eCatagory back to AudioCategory_Other again solve it.I still don't know what is wrong with it and what is the final solution.
Again I encounter the same problem and this time commenting (removing) the
properties.eCategory = AudioCategory_Communications;
solve the problem.
I can add my piece of advice for Windows Phone 8.1.
I made the following experiment.
Open capture device. Buffers are not silent.
Open render device with AudioDeviceRole::Communications. Buffers immediately go silent.
Close render device. Buffers are not silent.
Then I opened capture device with AudioDeviceRole::Communications and capture device works fine all the time.
For Windows 10 capture device works all the time, no matter if you open it with AudioDeviceRole::Communications or not.
I've had the same problem. It seems like you can either use only AudioCategory_Other or create an instance of VoipPhoneCall and use only AudioCategory_Communications.
So the solution in my case was to use AudioCategory_Communications and create an outgoing VoipPhoneCall. You should implement the background agents as in Chatterbox VoIP sample app for the VoipCallCoordinator to work .
I am having trouble using HTML::Mason's $m->comp to redirect from one view to another.
There is a file say file1.mi which has embedded HTML code in this file1.mi I am using $m->comp to redirect to file2.mi.
But in the webpage whenever file1.mi is loaded it prints the footer multiple times and in the logs i am getting the errors
Nested page framework application dispatch detected, this usage is not
fully supported and may result in unexpected behavior
and
Error: APPLICATION CONTEXT ERROR (RENDER): 32 levels deep in component
stack (infinite recursive call?)
. Here is the script which i am using for redirecting from file1.mi
return $m->comp('/page-framework/dispatch.mi', applicationPath =>'/gp/tradein/omc', viewID => 'file2.mi', %ARGS);
I am using this script in file1.mi before it renders the webpage -- i.e. before any HTML scripts are executed.
I am kinda new to Mason, if you have queries regarding this please go ahead.
It looks like that your file1.mi gets loaded and rendered, then file2.mi gets executed and it in infinite loop.
Please, show us more code, it is not possible to debug with that small details.
What do you in the web server logs? Please, paste some example from loglines too.
Regards,
It should be your dispatcher dispatch.mi that is calling file1 or file2. Deciding that you want to go elsewhere after the request has already been dispatched seems like the logic is in the wrong place.
We want to create a Windows desktop version of our weather widget
There are 2 special things about the widget.
It consumes a lot of processor time
while active - it displays an
animated picture (Flash without GPU acceleration, unfortunately).
It updates the weather from our
server (frequent server requests from all widget users).
When the user does not look at the widget there is no need for animation and weather loading.
So I have an idea of putting my widget to sleep when it is not visible and hense not used.
Is it possible to detect whether the widget is used or not.
Speaking precisely I need to know whether the widget is covered by other windows?
I mostly interested in Vista/7 gadgets engine, however I also would like to know if this problem is solved in these widget engines
Yahoo widgets
Google desktop
Hope to find some desktop widget guru here.

If you InvalidateRect and don't get a subsequent WM_PAINT message, than your window is hidden. You can call UpdateWindow after InvalidateRect to force the WM_PAINT message to happen (or not happen) right away.
So you could do something like this
request server data (and cancel request timer if any)
when data arrives InvalidateRect
when WM_PAINT message arrives, draw the data and set a timer for next request
when timer arrives, goto 1
When you stop getting WM_PAINT messages, you stop re-setting your timer, and you therefor stop requesting updates from the server. When the WM_PAINT message happens (because you are no longer covered). You start requesting data again.
