Re: [Easy400Group] HTML Variable Problem

Tue, 07 Feb 2006 15:54:15 -0800

Matt,

Back in May of last year there was a bug reported in the Easy400 under the subject "Garbage in HTML Output."

I posted a fix in message number 5623.  You can find it at http://groups.yahoo.com/group/Easy400Group/message/5623

It's likely that this fix is what you need.

Before applying this fix, it would be a good idea to make sure you have the latest CGIDEV2 version, 2005-03-10 20:21:21, and to back up member XXXWRKHTML.

Because IBM has taken control of CGIDEV2, Giovanni and I are unable to apply fixes or distribute updates.

Maybe IBM will soon release an updated CGIDEV2 containing this fix, other fixes, and perhaps some enhancements.

Mel -

I modified the code according to your advice (see above).  Unfortunately, I am still having the same problem.  I checked and allqrydta is NOT varying.  Any other ideas?  Is there a problem with the code above?

Thanks,
Matt

 Re: [Easy400Group] HTML Variable Problem







This could be related to whether field allqrydta is defined as varying or not.

If varying, the first two bytes at %addr(allqrydta) contains the current length which is returned by the %len built-in function.  The data would start at %addr(allqrydta) + 2. It is also for a varying field to inadvertently set %len(allqrydta) to the wrong value or to mess up the contents with pointer operations.

If allqrydta is not varying, the first two bytes contain data, not the length. In this case %len returns the size of the field in bytes.

If allqrydta is varying, the call to updhtmlvar2 should be:
 updHtmlVar2('openquery':%addr(allqrydta)+2:%len(allqrydta));  // note that 2 is added to the address.

Otherwise, you need to compute how many bytes of allqrydta are to be used (e.g. bytesToUse) and use that in the call to UpdHtmlVar2:
 updHtmlVar2('openquery':%addr(allqrydta):bytesToUse);   // note that nothing is added to the address

I have having a very strange HTML variable problem.  I have some HTML code that looks like the following:

<textarea name="openquery" id="openquery" rows="10" cols="80">/%openquery%/</textarea>

When I update the variable "openquery", it seems to overwrite the closing textarea tag.  By the way, we use IFS files to store our HTML source.  Here is the code in the RPG:

updHtmlVar2('openquery':%addr(allqrydta):%len(allqrydta));

I am using updHtmlVar2 because allqrydta can be over 2700 characters long.  

To keep the program from overwriting </textrarea>, I had to add 13 spaces following the closing '/' of the HTML variable.  That seemed to fix the issue; however, I am not satisfied.  I have not had this sort of problem in the past.  Everything was working fine earlier this morning and it started doing what was described without any major changes.  All I did was modify the HTML of a different section in the same document.  

I would like to know why this is occurring because we have several applications programmed using CGIDEV2 and I would hate to think they could all start experiencing similar problems.  Does anyone have any idea of what could cause the problem above?

Thanks,
Matt
