A generic DNN Search and Replace tool (virtually any table; e.g. "HtmlText"   , "Links" , "ModuleSettings", "TabModuleSettings", "DnnForge_NewsArticles_Page", "Tabs',  etc. (you can add yours).

Summary
=============

This ASPX page is self-contained. To work, it does not need any external stored procedure, DLL, vb or cs file. No module to install/register.
Just upload the ASPX page to your site (in any folder, even the root) and browse to it.
Before browsing to this page, you must be logged in as a super user (host).

Select the table (tablesList) where you want to search and/or replace data on the configured column (columnsList)
You can enter a term to search, and once you click on <search> a grid will display the results (may be in the future paging/sorting could be implemented)
The search  will look for the given string on the select table/column. The search will match 'contains...'
The search  will be case sensitive depending on your database configuration (the database collation). Typically (by default), the search is case-insensitive.

Clicking on <Search & Replace> will replace every instance of the search string with the defined 'Replace With' string.
An empty 'Replace With' is valid. Therefore, you can 'delete' text.
The replace operation is case-insensitive.
