1. How to solve LOGIC ERROR: Held resource owner

• Posted by sergelli Oct 09, 2011

In a large program, when I use:

getFontSize (WinMain)
or
setFont (PREVIEW,fontSize,Normal)

After using a few times (no problem), suddenly I get the error message:

Error code 425 LOGIC ERROR: Held resource owner is not the current owner.

Sorry for being annoying with many problems. It's because I'm migrating some development programs for the EU403, and many problems are appearing.
I can solve some, but others not, like this one, it is very difficult.

What is causing this? How can I fix?

Thanks a lot

Sergio

The library does allow that so there must be something else going on. If you've got a minimal sample program that demonstrates the problem I'd appreciate testing it here.

In the meantime, I'll try to reproduce on my system, the problem you describe.

Sorry, this is the smallest "code" I could do.

He is configured to do the error mentioned

I'm using this "infinite loop" to keep a semblance of the code (much greater)I'm having problems.

The above was done to try to reproduce an environment where we get an error "code 425"
This error can occur in lines that have instructions like these:

getFont ()
setFont ()

This is why I used them more than once.I know it seens stupidity

Please keep in mind that this code is just a small summary of a much larger code,
I summarized it, to facilitate the vision of where the error occurs.
But to generate the error, I need to keep statements that seem unnecessary here.

That's not what Derek request to analyze the error?

Do not think it strange that the error does not occur when using a different font in a MLE window?

I think I have a solution. Can you please try this and let me know if it works for you.

You need to change one of the win32lib include files. In the file w32resources.ew, in the procedure called traceObject, find the line ...

        if heldResource[at][ResOwner] = owner then 

and change it to ...

        if heldResource[at][ResOwner] = owner or 
           heldResource[at][ResObjType] = kFontObject 
        then 

Also, instead of the "while 1" loop you should consider using openDialog() to open the options window. This will keep focus on the options window until the user closes it.

No exactly bad but unnecessary. Here is what your routine could look like ...

function OptionsHaveChanged()  
	integer temp  
 
	openDialog(OPTIONSWINDOW)  
 
	temp = hasOptionsChanged  
	hasOptionsChanged = -1  
	return temp  
end function

Derec and Matt, thank you very much, resolved all the issues I posted here.

But did you also try my suggested fix?

Nothing that I can see. The fault was in my code inside win32lib.ew. Now that you have tried my suggestion and it works, I can permanently fix the library with this tested fix.
