Script who checks - and stop - if text has overset

[CS3 Notice update]

Oh ok, I wrote this post without knowledge of your CS3 notice. So it's helpless as doScript is only available for CS4+.

depends if the overflowing check has to be done before any action or can be the consequence of intial script actions. I think it's the second case given that you resize objects.

So here, you would probably want to undo previous operations if script couldn't proceed due to overflowing

var main = function(){

    var doc, pis, pi, n = 0,
    mItem,
    mBounds,
    mX,
    mY,
    _PDFExportPreset = app.pdfExportPresets.item('MyJobOptionName');
   
    if (!app.documents.length) return;
   
    /*
    if ( !_PDFExportPreset.isValid) {
        alert("Unable to find PDF preset");
        return;
    }*/

    doc = app.activeDocument;
    pis = doc.allPageItems,
    n = pis.length;
   
   
    while ( n-- ) {
        pi = pis;
       
        mBounds = pi.geometricBounds;      
        mX = getRound(mBounds[1],3);      
        mY= getRound(mBounds[0],3);      
          
        // fit content   
        if(mX == 10 && mY == 10){     
            pi.fit(FitOptions.CONTENT_TO_FRAME);    
        }  

        if(mX == 6.999 && mY == 4.801){    
            resizeItem(pi, 240,340)    
            pi.move([10, 10]);    
            pi.fit(FitOptions.CONTENT_TO_FRAME); 
        }      
   
        if ( pi.constructor.name == "TextFrame"
        && pi.parentStory.overflows ) {
            throw new Error("overflow");
        }
    }

    //makePDF(doc, _PDFExportPreset);
}
var doc = app.activeDocument;  


var makePDF = function(doc, preset) {
     var _PDFfile = new File('\\\\C:/test\\' + doc.name.replace (/\.indd$/, '.pdf'));  
    app.pdfExportPreferences.pageRange = PageRange.ALL_PAGES;                      
    doc.exportFile(ExportFormat.pdfType, _PDFfile, false,preset);
}


/* round */      
function getRound(number, digits) {      
        digits = (digits) ? Math.pow(10, digits) : 1000;        
        return Math.round(number * digits) / digits;        
}     
/* resize object */     
function resizeItem(mItem, mWidth,mHeight) {    
    mBounds = mItem.geometricBounds;    
    mBounds[3] = mBounds[1] + mWidth;    
    mBounds[2] =mBounds[0] + mHeight;    
    mItem.geometricBounds = mBounds;     
}  

var u;
try {
app.doScript("main();",u,u,UndoModes.ENTIRE_SCRIPT);
}
catch(err){
    app.documents.length && app.activeDocument.undo();
   
}
