Update to %`rs

I have been using %`rs to show a string, and update the string as the user proceeds through my code. But, it doesn't appear to work like I expect anymore.

I thought it had something to do with %ps tabs, but apparently not. I have the code below that illustrates the issue.

The %`rs appears in the main window and in Tab 1. Tabs 2 and 3 have a %rs in its other forms. for comparison. The button callback regenerates the text to be displayed and applies a counter to it.

I am using V8.66.0, and this problem shows in checkmate and release for both 32 and 64 bits.

	winapp
	PROGRAM MAIN
	use mswin
        integer,external:: abcd
        character*40:: rs_text
        common/rs_text_common/rs_text
        data rs_text/'This is the standard text for the %rs'/
        integer:: tabs(3),i,j
        i = winio@('%sh%ca[Tab 1]&',tabs(1))
        i = winio@('%`rs&',rs_text)
        i = winio@(' ')
        i = winio@('%sh%ca[Tab 2]&',tabs(2))
        i = winio@('%~rs&',rs_text,0)
        i = winio@(' ')
        i = winio@('%sh%ca[Tab 3]&',tabs(3))
        i = winio@('%rs&',rs_text)
        i = winio@(' ')
        i = winio@('%ww%^bt[Change Text]%2nl%`rs%2nl%3ps[ms_style,hot_track]',abcd,rs_text,tabs(1),tabs(2),tabs(3))
        
        end
        integer function abcd()
        character*40:: rs_text
        common/rs_text_common/rs_text
        integer:: i=0
        abcd = 1
        i = i + 1
        write(rs_text,*)'This is now click number',i
        call window_update@(rs_text)
        return
        end

I have taken a quick look at this and I can confirm that Bill's observation of there being a change in the behavior of %`rs

In my case, the problem occurs with the following line, where run_up_time is updated at the end of a calculation. This is similar to Bill's %`rs in the main window.

iw = winio@('%2nl%ws%ta%8`rs&','Run up time [s]',run_up_time)

Looking at my diary, I think the change in behavior occurs with the updates provided after June 2020.

PS: my code runs correctly with the earlier newDLLs50, but not the most recent newDLLs51.

I did also confirm that this does NOT occur with %rd or %rf.

Thank you for the feedback.

The ClearWin+ library code for %`rs was changed on 25 September 2020 in order to make it work as intended in the design.

It is unfortunate that this correction now look like a regression from the user's perspective.

At the moment it is not clear to me how this should to be resolved.

Paul, I don't understand what the 25 Sept change was intended to do. Since this option no longer works as the documentation states, I guess I am just confused what drove this change.

Now, this works just like a %ws. I'm fine with %ws when needed, but I really need a %`rs or I'll need to replace dozens upon dozens of instances with ?????.

I have now worked out how to resolve this issue and will aim to get back to you with a fix fairly soon.

I remember as a child watching a Laurel and Hardy cartoon where they drilled mouse holes only to plug them up again. This could be similar.

Paul,

I, too, have had to 'plug the mouse holes' after doing something that seemed, at the time, a reasonable thing to do/try. In fact, it was under a month ago, and I went way too far and got things so balled up my only recourse was to reload from my backup. The ultimate 'plugging'.

Thanks for addressing this. I look forward to completion.

There seems to be two issues here.

I can restore the behaviour for the %`rs that is not in a property sheet but it seems to me that the one within the property sheet was not 'working' before this regression. The latter issue remains outstanding.

Paul, I may have not been clear. The original problem was noted by me in a new program that exclusively uses property sheets. I thought it was this usage that was causing the problem. The test code showed it occurred in both usages. I'm not remembering that there was a reported issue about just in property sheets.

I have found in property sheets that an explicit call to window_update@() is needed for some variables to update. Is this what you are referring to? I've no problem with explicit updating!

Bill

I am still confused by this.

In your experience has %`rs ever worked as you expect when used in a property sheet?

My memory is that it worked in property sheets, but I had to give an explicit window_update@() for it to properly show. Thinking back, I remember a month or so ago running the code with a customer remotely, and not seeing the expected results show in the %`rs position. I ignored it, looking to get back to it later, and forgot to log it.

I'll (carefully) re-install DLLS50 (per Kenneth Smith note) and see if it runs as I expect it to after that.

Bill

I searched my code for a current instance where a %`rs appeared in a child window. I cannot find anything. That is not to say that it did not occur in a previous version (still in development).

I can say that DLLS49 (my last downloaded version) does allow the %`rs to update in the main window when explicitly commanded. DLLS51 does not.

Since my current code uses change_help_text@(), DLLS49 prevents me from properly linking.

Both these issues have now been fixed for a future release of the ClearWin+ library.
