Hi All,
My first post in the forum. I have searched previous posts but could not find relevant info hence the post. Please correct me if my post is in the wrong forum.
This is regarding an error during string manipulation using "String Replace" action item.
The action item should replace some text from the resource file in the string variable.
This action fails and when I saw the log, it fails at a particular place. I saw that one of my dialogs control has "%" as the caption. Somehow the string replace action item is not able to parse this line. -
LTEXT "%",IDC\_STATIC,249,499,10,10"
Could some one help me?
If I replace the caption from "%" to any other text like "percent" then it works fine.
Thanks,
MedDev

Hi
Can you send us (to support at finalbuilder dot com) your finalbuilder project file, and the resource file you are working on so we can see what is happening as we have not been able to reproduce this here.
