The Help and Samples (for both Delphi and C++) are very useful when Programming as they provide quick reference and examples of how to use different language and component features.

If you are using the RAD Studio IDE and find that F1 is not opening up the help files, then the most likely answer is that the Help installation was skipped during the initial install.

To check (and install if missing) go to Tools > Manage Platforms

This dialog allows you to install additional platforms, but also (under Additional Options) manage the installation of Help and Samples.

Simply, tick the box for Samples and Help and then Apply, and you should then be ready to use F1 help in the IDE.

How to create Auto Incremental Fields in RAD Server with InterBase, FireDAC and TEMSDataSetResource

One key feature when asking a remote server to add a record is to get the new record ID value returned. Thankfully this is easily achieved with InterBase and FireDAC via RAD Server with TEMSDataSetResource

InterBase has a concept of Generators. These provide a unique sequential integer value that can be used to provide a primary key field value. You can create up to 32,767 Generators in an InterBase database, but typically you would create one for the database or create and name one for use per table.

• InterBase Labs Video on Generators
• DocWiki documentation for Generators

FireDAC Query UpdateOptions AutoInc

Part of the FireDAC framework is the ability to treat database fields as Auto-Incremental Fields. For Databases that do not have an AutoIncremental field data type, you can set the UpdateOptions properties to define the Generator and key fields.

InterBase ToGo Update for Android

Following an update to OpenSSL to address some identified vulnerabilities, Google has stopped allowing submission of applications that contain certain versions of OpenSSL libraries.

While InterBase ToGo and IBLite are not affected by the vulnerabilities identified, the current build that is shipped with RAD Studio for Android is being stopped from deploying to the Play Store. To get around this issue, please download the latest build for InterBase ToGo and replace the .a file in your local deployment files.

While tested on 10.1 Berlin, this download should work for any RAD Studio customer who’s product shipped contained InterBase XE7 (XE7, XE8, 10.0 Seattle and 10.1 Berlin).

Download the latest Android InterBase ToGo from Code Central

Where to put the file?

The InterBase ToGo library for IBLite and InterBase ToGo is the same file. This is typically found at

• C:\Users\Public\Documents\Embarcadero\Interbase\redist\InterBaseXE7\android

You may also need to check for

• C:\Program Files (x86)\Embarcadero\Studio\18.0\lib\android\Debug\
• C:\Program Files (x86)\Embarcadero\Studio\18.0\lib\android\Release\
