Description:
I will firstly describe what I’m trying to do. All this is my pet project, so it doesn’t matters on cleanliness of final solution. I wish to notify my other app whenever any user mute/unmute theirs mics. I’m absolutely new in C++ (my native language is java or C#). I understand, that is quite dummy question, and it will probably have its roots in my poor knowledge of topic. But I would like to ask you for help with start. I found the place where I should start coding and tried to add simple print out. But it doesn’t work. I tried to popup error message, but it doesnt work as well. And I could not find any misstake in my added code:
Method is in sdk_util.h.
Nothing happnes after I (or other participants in iniciated call) click to theirs “mute mic icon”. What am I missing?
I run my app from relase configuration, because it crash from debug (running as debuge could solve my difficulty as well). What could I do to see any output (printed output to console, messagebox, debug mode or anything else)? Is there some topic about it?
There are no dummy questions. If anything, asking “dummy” questions is the fastest way to get better.
Unfortunately, the SDK can only run in release mode. However, there is a way to see if your callback is being triggered. Inside of your onAudioBtnClicked function, add __debugbreak(); This will stop the the application at that point, similar to a breakpoint. You can also put __debugBreak(); in your WinMain to see how it works. If your application does not pause at __debugBreak(); when you click the button, the callback is likely set up incorrectly. Which we can troubleshoot after.
std::cout does not behave the same way in c++ Windows GUI applications as it does in c++ console applications, so you wont see those print statements unless you add functionality for it. However, you can make a test text file that std::cout can write to. This stackOverFlow post explains this well: https://stackoverflow.com/a/191912
Can you try this and let me know what happens, then we can troubleshoot from there?
Thanks for such a great answer Everything is ok now. I found that I was doing wrong thing in the wrong place. Right spot to do the job was not virtual function. After reading some basics about C++ is it clear, that virtual function is just (as it said) virtual representation of function. So I found this: in custom_ui_mgr.cpp file. And that do excatly the job I need. Breakpoits work fine. It makes my day.
Thanks for all your support.
