Need to save to a different format

Have source code for software which saves text box information to an ini file. The problem is each text box is limited to 999 characters in an ini file. After that the line breaks so when the ini file is called again, anything after the line break is not inserted back into the text box. I need this program altered to save an unlimited amount of information in a text box and then be able to recall the information when the file is opened. This is a simple project for a programmer who knows what they are doing. I need this done ASAP. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform All Windows Systems
