Title : Search Text in files
Author : Bobysait
Posted : 1+ years ago

Description : Create a window with some gadgets :
- a textfield for the directory and a button to "requestDir"
- a textfield for text to search
- a textfieldK (you'll find the code source in the code archive - miscellaneous) to set the recursivity
- a button to launch the search

result happens in a textarea
(it could be replaced with a listbox which would be better)

source of the mdt.uisdk is below this post
-> copy/paste the code and save it to "uisdk.bmx" then put it in your mod folder with this path
$blitzmax_path/mod/mdt.mod/uisdk.mod/

($blitzmax_path is your blitzmax path ... obvious enough)
