Embarcadero SummerSchool 2013 Lesson 4 Q&A

Posted by jpluimers on 2013/07/25

Replay video’s can be viewed through streaming.embarcadero.com (where you can also find the other series, downloads, etc).

The SummerSchool 2013 replay videos are at streaming.embarcadero.com/summerschool2013.

The Q&A from today’s session on “Accessing local storage” demonstrating iOS specifics in Delphi XE4:

Audience Question
Q: If I program 2 different applications with connection to a local database – is it possible the both programs use the same local Database? Or has Program 2 no access to the database of program 1 ???
A: On iOS apps are sandboxed. SO you will need two databases (if using on the device storage) You can have 1 database in the back end using DataSnap/Soap to help syncronise data. We will look at this later in the season (lesson 5&6) especially easy direct DB access with DataSnap.

Audience Question
Q: I need an encrypted local database, which can i use on iOS?
A: InterBase ToGo will be the best option. Email me about what you are doing and we can chat further.

Audience Question
Q: Do you have any example on how to access the photos directory?
A: Photo Editor Demo

Q: Good morning!
Q: I missed the email invite for lesson 3. Only for lesson 4. Did invites for lesson 3 get out?
Q: Make more clear that you have to takt the poll in the webinar screen. That was not obvious to me.
Q: I thought it was just a PPT slide.
Q: Then I saw the % in the next page.
Q: You can also use IncludeTrailingPathDelimiter
Q: (Boy I dislike that sometimes you guys use abbreviations and sometimes you don’t. Make a choice. Stick to it)
A: We do tend to use abbreviations, but only once we have said what they are. Sorry if there is confusion or we get this wrong from time to time.

Q: I missed the email invite for lesson 3. Only for lesson 4. Did invites for lesson 3 get out?
A: The same link works for all sessions (incase you want to add a manual reminder to your diary). Tuesday and Thursday next week are the last two in the season
Q: I mean abbreviations in the RTL code. R&D has to make a choice, then stick to it, and Q&A has to be anal into watching it.
Q: TIniFile is great btw: glad you guys made that X-platform.
Q: The advantage if IncludeTrailingPathDelimiter is that only will be added if needed (depending in the running platform).
Q: I usually have a function like “GetRoamingDocumentsPath” for stuff that lives in a Roaming/Cloud environment.
