/*  
 * v1.0 Edited by Jing and Omair   (05/11/2005)
 * -Fixed FileDialog box; made modal with respect to "this class" so that when it is clicked it stays on top.
 * 
 * -Fixed Save as .bat --> so that now when there's incorrect *.ma filename or if there's no filename
 *  you won't be able to save a *.bat file. 
 * 
 * -Fixed Error in testString()
 * currently the function is setup so that it seeks numbers in the string [no matter where] and contatenates them, adds 1 to the concatenated number and appends the number to the end of the string. 
 * so if you make a file name called 4567i and you overwrite the file [using automatic] you will get a new file called: 4567i4568 when it should be 4567i1
 * Fix: rewrote the function by checking from the back instead of from the front to find the location of a character. Then the numbers [after the char] will be chopped off as a substring and returned.
 * 
 * -Fixed Error in setDigit()
 * When trying to save a *.bat file called "2" and saving another file called "2" using the automatic save will result in either window not responding or nothing happens. 
 * Fix: altered the setDigit() [no more index out of bounds exception] so that when filename is a number it returns a string representation of the newly updated number.
 * 
 * -Fixed Error when closing window
 * Bug: When window is first opened, it will not close when clicking on the "X" (close button at the top right corner of window)
 * Fix: set OK2Close = true by default so that window will close.
 * 
 * -Fixed Error for when canceling browse
 * BUG: When there's a file in the text box [text box filled] beside the browse button and if browse is clicked and you hit cancel to "cancel" file selection. 
 * The file name will be erased from the text box [empty text box] and you will have to reselect the file. 
 * Fix: Check for if the file returned from the file selection is equal to "" [nothing] if so then don't update text box field.
 * 
 * -Fixed error which occurs if the root directory of eclipse has spaces in it
 * Bug: If the root directory of eclipse has spaces in it then this button didn't function at all
 * Fix: We need to enclose IPath objects namely path and internalPath in double quotes by simply concatenating
 * their string representations by "/""
 * 
 * -Fixed error which occurs if any fileNames have a space in them
 * Bug: If the for e.g. say a .val file has spaces in it then an error will occur terminating the function 
 * immediately
 * Fix: All filenames were enclosed in double quotes which was done in collect parameters
