Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

  • a5_AJAX_Callback()

    Hi All,

    I am trying to use the a5_AJAX_Callback() on a dialog with some limited success.

    I have created two pages the first with expression web as below

    Code:
    <!doctype html public "-//w3c//dtd html 4.0 transitional//en">
    <html><head><title></title>
    <meta http-equiv=Content-type content="text/html; charset=unicode">
    <meta content="MSHTML 6.00.6000.16825" name=GENERATOR>
    <script type="text/javascript" src="javascript/core.js"></script>
    <script type="text/javascript" src="javascript/AjaxFormLibrary.js"></script>
    <script type="text/javascript" src="javascript/aui.js"></script>
    
    </head>
    <body>
    <p><form method="post"><textarea id=Questions_Q1 name=Q1></textarea></form></p>
    <p><form method="post"><input type="submit" id="submit2" name="submit2" value="Submit Query" onclick="a5_AJAX_Callback('Questions.Ajax.A5W','action=SayHello&amp;name='+urlencode($('Questions_Q1').value)); return false;" ></form></p>
    </body></html>
    This works fine, the second page I have created with Alpha code is below

    Code:
    <html>
    <head>
    <base href="file:///C:/Program Files/a5v9/">
    	<!-- must use in order to make XP Themes render -->
    	<META HTTP-EQUIV="MSThemeCompatible" content="Yes"/>
    
    <link rel="stylesheet" type="text/css" href="css/BusinessSchool/style.css">
    <link rel="stylesheet" type="text/css" href="css/BusinessSchool/components/a5SimpleForm/style.css">
    
    
    <script type="text/javascript" src="file:///C:/Program Files/a5v9/javascript/core.js"></script>
    <script type="text/javascript" language="javascript">
    <!--
    function Questions_Init(){
    };
    $e.add(window,'load',Questions_Init);
    //-->
    </script>
    </head>
    <body class="BusinessSchoolPageBODY">
    
    
    <form id="QUESTIONS.DIALOG" name="Questions"   style="margin: 0px;"  method="POST" action="">
    <input type="hidden" name="Questions_hidden_test_variable">

    </tr>
    <tr>

    <table cellspacing="1" cellpadding="3" style="border: none; width: 100%">
    <tr><td  class="BusinessSchoolDataTD" >

    </td>
    </tr>
    <tr><td class="BusinessSchoolColumnTD"><label id="Questions_RADIOBUTTON10.L" for="Questions_RADIOBUTTON10" >Please Select</label></td>
    </tr>
    </table>
    </td>
    </tr>
    <tr>
    	<td class="BusinessSchoolFooterTD" nowrap colspan="4" align="Right">
    	<input class="BusinessSchoolButton"  style="" type="submit" value="Submit" name="submitButton">&nbsp;
    <button class="BusinessSchoolButton" style="" name="next" value="AdvancedButton" id="Questions_NEXT" onclick="a5_AJAX_Callback('Questions.Ajax.A5W','action=SayHello&amp;name='+urlencode($('Questions_Q1').value)); return false;" >next</button>
    <input type="hidden" name="hidden_next" />	
    	</td>
    </tr>
    </table>
    </form>
    </body>
    </html>
    This does not work, I am trying to write back to the textarea id="Questions_Q1"

    The callback page is very simple. I have taken the basic one from the examples and used that for a lookup as I said it works fine with page one but not with page two, the callback page is below, can anybody tell me where I am going wrong

    Code:
    <%a5
    
    dim action as c = default ""
    
    if action = "SayHello" then 
    	dim myReply as c 
    	dim name as c = default ""
    	myReply = lookupc("f","ABC0013","Question","[PathAlias.ADB_Path]\questions","Qno") 
    
    		
    	dim myResponse as c 
    		
    	
    	myResponse = "$('Questions_Q1').innerHTML = '" + jsEscape(myReply) + "';"
    	?myResponse
    
    
    end if 
    
    function jsEscape as c (txt as c)
    	jsEscape = stritran(txt,"'","\'")
    	jsEscape = stritran(jsEscape,crlf(),"\n")
    
    end function 
    
    %>

    Re: a5_AJAX_Callback()

    Hi Andy,


    OK 1.
    You must include certain js files for AJAX callbacks to work


    eg
    Code:
    <script type="text/javascript" src="javascript/core.js"></script>
    <script type="text/javascript" src="javascript/AjaxFormLibrary.js"></script>
    <script type="text/javascript" src="javascript/aui.js"></script>
    however these don't always work correct when using this
    Code:
    <base href="file:///C:/Program Files/a5v9/">
