    i've try to modify and modify...
    but I can not get it to work ...

    In the last, I've try to insert my "filterComments" function inseide the file, in this way is inside of the iframe, now work until che line
    var innerHTML = Lianja.evaluate(execute);

    but I think it's still the right way ..

    If I enter the "filterComments" function inside the iframe .. then when the call again, I create a new iframe ... inside the iframe ..

    The best is, from the iFrame, call the function in the page, delete the frame then recreate...

    but from the frame, onchange="window.parent.filterComments('Z')" not work..

    thanks
    Fabio

    Code:
    <script type="text/javascript">
    function filterComments(m_empty)
    {	
    		window.Lianja = window.parent.Lianja;
    	
    	var search_str;
    	var data = "cod_art,catmercgam,des_web";
    	var dataquery = "cod_art|,catmercgam|,des_web|";
    	var table = "aricoli";
    	var cursor = "cur_articoli";
    	var caption = "Cod. art,Cat merc,Des WEB";
    	var target = "cod_art";
    	var	execute = "";
    	
    	var datasets = [];
    	var querysets = [];
    	var i;
    	var value;
    	var	query = "";
    	var valore;
    	
    	window.alert("FilterComments");
    	
     	if (data.indexOf(",") > 0)
    	{		
    	
    		window.alert("Data ok");
    		datasets = data.split(",");
    		querysets = dataquery.split(",");
    				
    		for (i=0; i<datasets.length; ++i) 
    		{
    			window.alert("1");
    			value = datasets[i];
    			
    			if (m_empty == "X")
    			{
    				valore = "";
    				valore = querysets[i];
    			}
    			else
    			{	
    				window.alert("2");
    
    				valore = document.getElementById(value).value ;
    			};
    			
    			query = query + ";" + value + "|" + valore;
    		}			
    		
    		window.alert("Query ok");
    		
    		query = query.substr(1);
    		document.getElementById('Query').innerHTML = 'Query = select ' + table + " where " + query;
    		
    		window.alert("prepara execute");
    		execute = 'sup_Search_sectionRefresh("' + table + '","' + cursor + '","' + query + '","' + caption + '","' + target + '")';
    		window.alert(execute);
    		
    		var innerHTML = Lianja.evaluate(execute);

    Hi Fabio,

    How are you specifying the parent rsp file, is this set as the WebView Section's Data 'Custom filename'?

    If so, set it in the URL instead and specify it using the internal web server, e.g.

    Code:
    http://localhost:8002/desktopwebservice/pagex_sectionx.rsp
    Then when you create the iframe, you will not have cross-domain issues and calling parent.filterComments('Z') will call the function in the parent.

    Regards,

    Yvonne

    Hi Fabio,

    When you specify the iframe source as "http:/localhost:8002/...", your original rsp file (on C: or other drive) and the iframe file are treated as being in separate domains, which stops you doing lots of things in JavaScript. In your case, the parent.function() can no longer be called and the Lianja object reference is not inherited from the parent.

    So, try specifying the rsp file as a URL through through "http:/localhost:8002/..." as well as the iframe.

    For anyone else using the internal web server, remember to Enable services in the App Settings:

    (easily forgotten - or is that just me )

    Regards,

    Yvonne

    now I understand .. :-)
    thanks, I try.


    But returning on the main question: is possible read a ASCII file..

    reading this post (http://www.lianja.com/community/show...-Web-service):
    If the result returned starts with "file:" then the file specified e.g. "file:mytempfile.txt" is read and the result is sent back to the client. This provides the ability to query large amounts of information not limited by internal string length.
    If the result returned starts with "tempfile:" then the file specified e.g. "tempfile:mytempfile.txt" is read and the result is sent back to the client. The file mytempfile.txt is then deleted.

    I felt it was possible to read the file ..
    and much simpler ..

    I call my rsp page with a showdialog command,

    I've try:
    Lianja.ShowDialog("Search & Find", "http:/localhost:8002/desktopwebservice/sup_search.rsp?table=vt_articoli_artico...
    or
    Lianja.ShowDialog("Search & Find", "http:/localhost:8002/library/sup_search.rsp?table=vt_articoli_artico...


    but not work...

    Hi Fabio,

    Try copying sup_search.rsp to the App.

    Regards,

    thank for the support Yvonne,
    I've try:
    Lianja.ShowDialog("Search & Find", "http:/localhost:8002/desktopwebservice/sup_search.rsp?table=vt_articoli_artico...
    or
    Lianja.ShowDialog("Search & Find", "http:/localhost:8002/sup_search.rsp?table=vt_articoli_artico...

    but not work... the page is empty..

    by the way, when I try to use the Web Inspector, the window is "under" the dialog .. then you fail.

    now, I give up to this solution..

    I look forward to a few examples ...

    but I can not do what I read in the post?
    reading file to exceed the limit of variables, which are at most 64k ...

    If only you could compress .. my 63k file, zipped becomes 4k ..

    But you can read a file from a page rsp, would be better ..

    thanks
    Fabio

    Hi Fabio,

    Did you put two / characters after http: or only 1 as in your post?

    Regards,

    Yvonne
