Documentation has been an issue in the past, but has been addressed with a new online Documentation Server. Alpha is very attentive to Documentation requests where end user developers will suggest enhancements for the documentation and it's now there within days. Some features, like the FormView Control, seem very complex and maintaining a working knowledge over time is tough.
Follow the many, many excellent Tutorials.
Utilize the pre-designed Template Components to learn basic concepts.
Read the Release Notes, and Pre-Release Notes every day. Watch the excellent videos accompanying almost each new feature release.
I'm an independent developer working with database environments from mainframes to PCs for over 40 years. Alpha Anywhere allows me to assist companies and other developers worldwide with web development, hybrid web/mobile and mobile development for projects ranging from farm safety in Australia, mobile site security involving NFC tags in Australia, mobile service forms in Canada, PTO/PTA Management Systems in the US and many others. I get to help lend a hand to those building businesses. Alpha Anywhere allows me to have any number of different released versions installed which is immensely important since many of the projects I work on stay with different specific versions for long periods of time.
