Hi,

We have seen most methods to populate  Combo.  I would like to share another way, which is an important one.

In this example, we will import Combo items from a Text File. This file has comma separated values ( techies call em CSVs ). In our case, each line in the Text File will contain Text and Data separated by a comma.

To separate each line into Text and Data and insert them into the Combo, we will use a function called DelimitedStringFunction ( available in the AMS software Script Gallery Folder ). I placed this function in the Global Panel.

For this example, I use a Button to import data from the Text File. If you want to load items directly as your App starts, just Copy the scripts in the Button and Paste it in the Page OnShow.

This example extends the previous example with an “active” ListBox.

> ListBox OnSelect will read a TextFile and fill the content into a Paragraph

> ListBox OnDoubleClick will open a Dialog Box containing Text and Image.

> Only 1 Dialog Box is used and will pull items on the fly.

Our previous examples show how to call Dialogs from Combo Box. However, content are hardcoded into several DIALOGS.

Lets see how to use a single Dialog Only to insert different Text and Image into it when we made a selection. Saves lots of bytes and time. The IMAGE which is set into the DIALOG PAGE will maintain its aspect ratio by using Worm’s function.

Also, we use  BUTTON to open relevant TEXT FILE. This method can also be used to launch all types of files either resident in AMS Source Folder or PC. It will open in its native app. Knowing this will help us very much in development.

This simple example can easily become applications such as E-Album, E-Catalogue, E-Archive and DeskTop Teaching Software. To make it more intelligent, connected and interactive, add Dermot’s and Reteset’s plugins to it.

> From Combo, it pulls text to Labels.

> From Combo, it pulls relevant info from a Text File and set them into Paragraph.

> From Combo, it pulls relevant Image to the Page

> No Dialog Box

> We maintain the Image’s aspect ratio by using a Global Function created by Worm.
