We have this legacy code (meaning dont blame us) in OI9 that works differently in OI10

in OI9 - Pic from the send_message is 1

in OI10 it is 1-1

therefore: Pic = Not(Pic-1) + 1 gives a nonnumeric error.

So, is the code in OI9 wrong and they got away with it or is there a bug in Oi10

If code in OI9 is technically wrong, what should it be?

values in debug in Oi9 & OI10 are

Pos=14

List<14> = 1:CMM - Test

Pos  = Get_Property(Users$, "SELPOS")

		List = Get_property(Users$, "LIST")





		Pic = Send_Message(Users$, "UPDATE", Pos, "")

		Pic = Not(Pic-1) + 1



		Send_Message(Users$, "UPDATE", Pos, Pic)

Barry,

The v9 implementation has some inconsistencies that made backwards compatibility "interesting" to implement, and, TBH I thought this had been taken care of, but I'll take a look.

However, before I can, some questions:

Is this a v9 Heirarchical ListBox that's been migrated into v10? Or is it a "normal" one? How is the list set?

Can you supply an RDK that illustrates the problem so I can reproduce here?

Otherwise you might be better off using some conditional compilation if you're sharing the code between v9 and v10

Thanks

Yes - it is normal and OI10 shows as LISTBOX

I changed code to this for OI9 & OI10 to work in both:

Pic = Send_Message(Users$, "UPDATE", Pos, "")[1,1]

PS:

I have another issue with an Heirarchical ListBox on a form.

OI10 shows as TreeListBox - should I recreat it in OI10.

Coding manipulation for it is very complex and I have no experience with listboxes, so I dont know what I am looking for.

The code does a 'select all', shows all boxes as ticked, but when saved and re-read they are unticked.

Ticking them individually appears to work.

Any hints - or what I should be looking for in incompatibilty.

You would be better off recreating it - Listbox/Checkbox programming in v9 and earlier was done with image manipulation more than likely using the UPDATE message - I expect you need to look at the image being set if you are sticking with the v9 code.

In v10 checkboxes are supported "natively" so there is a series of actual properties for manipulating them:

CHECKBOXES - Boolean property - turns checkboxes on or off

CHECKED - gets or sets the items checked. The value can be:

1) An @fm delimited list of boolean flags denoting the checked status of each item,

2) A single boolean value withe the item number passed in the index parameter

3) "*" check all the boxes.

CHECKEDX - Same as CHECKED but only for TREELISTBOXES and returns data for the fully expanded list (list LISTX etc)

CHECKEDLIST - Returns an @fm'd array of item numbers that are checked.

CHECKEDLISTTEXT - Returns an @fm'd array of item text for the items that are checked.
