If you want to use all the examples from AMS 5 to AMS 7.5 in your AMS 8 projects, please take note below.

AMS 8 is using an updated version of LUA 5.1. One of the most important change is the TABLE ITERATION.

This is the old code used in AMS 5 to AMS 7.5 for TABLE ITERATION ( loops )

-----------------------------------------------
mytable = {"One","Two","Three"};

for k, v in mytable do
Dialog.Message("Table Item", k .. "=" .. v);
end
-----------------------------------------------


If my examples are using LOOPS, you need to change like below:


----------------------------------------------
mytable = {"One","Two","Three"};

for k, v in pairs(mytable) do
Dialog.Message("Table Item", k .. "=" .. v);
end
----------------------------------------------


See the word “pairs” in red and the bracket, above?

Just add a BRACKET around your TABLE NAME and add the word “pairs“.

Then all my examples using loops will work.

lol ….. 99.9 % of my examples are using LOOPS.
You’ll definitely have to change the codes.

Hope this helps.

Been some time. Was busy setting-up a new office in Kuala Lumpur. In between activities, I spared some time in transforming our previous project. Move over Text Files, here comes SQLite database.

The SQLite DB file is located in MyDocs (XP/P8/ME) or Documents (Vista) hosted in the folder named as MyResourceFolder. The folder and DB file will be created automatically when launching this App.

Mini Address Book with SQLite DB

Some minor changes were made to the interface. I’ve also added more details but the functions remain the same:
1. Add New Entry
2. Delete Entries
3. Edit Entries
4. Search Entries
5. Group Entries
6. Rename Groups
7. Delete Groups
8. Share Items between Groups
9. Make a New Group from Search Results
10. Validate All Entries

Mini Address Book with SQLite

Since this Project uses SQLite, we have removed previous concerns. We can now
1. Update Entries shared by several Groups all at once
2. Search every row in the DB directly without any help from ListBox.

Mini Address Book with SQLite

For each item ( every DB row ), you might only see 4 data on the interface. In actual fact, this project is prepared for more than 10 data per item. This includes the usual suspects like Address, Zip Code, Street Name, Country, Birthday, Description, Notation and etc. I encourage readers to try embed more entries at the interface. This is the way to learn.

If you add Dermot’s Pop3 Plugin, you’re making an almost full-featured Email App. To learn more about SQlite DB on AMS, please view TJ Tigger’s Video.

In the next topic on Mini Address Book, I plan to add 2 more features:
1. Photo for each Name
2. Calendaring.

We’ll see how it goes. If there is a request, I will make create another example just for the Search Function. Please use the comment in the Blog.

And please, leave your comments in this blog.

Hi,

SQLite DB is a good option if you plan to have a long list of data in your apps. Its quicker, its more efficient and works faster than text files or XML.

When you combine SQLite with Grid, you’ve got yourself an app with tremendous potentials.

The example I’ve added today, shows how to combine these 2 powerful AMS elements, albeit in a very simple way. You can develop further from here. Remember to put ERROR CHECKING, if you plan to distribute apps.

Hi,

We have seen various examples on how to use Combo Boxes. So lets put together some of the examples into 1 APZ and make it into something more practical to use.

In this example, we will ADD/DELETE/EDIT a SQLite DB Table through the use of the Good Old Dialog and reflect all changes in a COMBO Box instantly.

This example affects only 2 Columns of each Row and shows the use of various SQL Queries. If you need to affect more Table Columns in a DB Row at one go, then replace the Dialog with DialogEx. Please refer to an earlier example on how to use DialogEx for Data Entry. Of course, you need to create more Column Names for the SQL Table. I leave it to your ingenuity.

Dialog To DB to Combo

All of the previous examples use TABLES to populate items into Combo Boxes. This is an economical and quick method when dealing with items such as Dates, Names of Days, Names of Months, AM/PM, Gender, Number of Children, Race, Marital Status and other small list.

For larger lists, we prefer to use SQLite DB.

This example shows how to populate Combo from DB on program start-up and how to populate a second Combo from DB upon selection. When an item  in the second Combo is selected, data is pulled from DB and set into the Paragraph.

Please note that, when SQL files are located in AMS Docs Folder, it cannot be modified after compiling. To enable modifications, SQL File must be located on the writable space of user’s PC.
