How can I change the text displayed when user enters wrong username or password ?
The string is located in the App_GlobalResources.dll that contains all the code-behind resource strings for Process manager. The string is MainRes.InvalidUsernamePW. If you have access to a resource editor, you should be able to change this string.
I was not able to find the string in this DLL. Are you sure is the right one ??
It's the 4th string down in this picture
