we have compiled some common questions that came to us directly from some of you. Let us know if you have further questions. Q: Is it possible to customize meeting id – i.e show our own unique meeting id instead of zoom meeting id? Also, how do I customize the app icon? A: you can change it with the following method: IMeetingService SetMeetingIDForMeetingUITitle(ulong meetingNumber) You can customize the icon by replacing sdk\_demo.ico and small.ico in the project.   Q: How do I switch video types? A: check these functions: SwitchFloatVideoToActiveSpkMod() SwitchFloatVideoToGalleryMod() SwitchToVideoWall()   Q: can I switch language in the SDK ? A: yes, under struct tagInitParam, there is an attribute: SDK\_LANGUAGE\_ID emLanguageID which you can select.   Q: Can I localize on my own to a language that is not supported by the SDK ? A: yes – resource files are included in sdk\_demo.rc   Q: How to access Zoom Contacts in SDK? A: we don’t support IM and presence functionality in the SDK as of now   Q: Can I customize invitation email? A: yes, under MeetService class, there are two function calls: GetInviteEmailTitle() and GetInviteEmailTeamplate(). You can always add new content into it.   Q: How can I track meeting quality? A: we provide an API call: MeetingService::GetMeetingConnQuality to track meeting session quality.   Q: Is it possible to launch a meeting with the app share option similar to your iOS stack ? A: you can pass a window handle to the stack and start the share but you cannot pass single image file – we are looking to releasing that soon   Q: Looks like your SDK is written in C++ - if my application is written in C#, how can I access the SDK ? A: We have provided an abstraction layer for C# applications. Please check out the download page. ---
