Hi there
The fact that on the Files tab, one is able to open a file with an external program got me thinking this morning. What if I can write a B4J app, that can get passed the file name I selected, then process something inside the file and save it back.
So I wrote a small script for something that I do almost often. Add a new page to my existing B4J app. To test my theory I created a form with a text area and created a UI app called NewPage...
What the code above does is to open the selected file, read its contents, display the contents in a text area in a form after appending the code to Show and Close a form.
After compiling this app, I needed to configure the external viewers..
Then I right clicked on the file, selected Open with NewPage and yippiee!! See the gif.
Now, what if the functionality to Open With could be available on the Modules tab? Me thinks the possibilities are endless..
