Replace Module Text in MS Access using VBA

Question

How do I do a search and replace of text within a module in Access from another module in access? I could not find this on Google.

FYI, I figured out how to delete a module programatically:

Call DoCmd.DeleteObject(acModule, modBase64)

Answer 1

I assume you mean how to do this programatically (otherwise it's just ctrl-h). Unless this is being done in the context of a VBE Add-In, it is rarely (if ever) a good idea. Self modifying code is often flagged by AV software an although access will let you do it, it's not really robust enough to handle it, and can lead to corruption problems etc. In addition, if you go with self modifying code you are preventing yourself from ever being able to use an MDE or even a project password. In other words, you will never be able to protect your code. It might be better if you let us know what problem you are trying to solve with self modifying code and see if a more reliable solution could be found.

After a lot of searching I found this code:

''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
'Function to Search for a String in a Code Module. It will return True if it is found and
'False if it is not. It has an optional parameter (NewString) that will allow you to
'replace the found text with the NewString. If NewString is not included in the call
'to the function, the function will only find the string not replace it.
