WinDev 20 - control is unknown

Startbeitrag von Tor-Bjarne am 17.06.2015 14:12


In WinDev 20 I have a window whoes name is Win_LabZ, this has a local procedure called ReadDataBC.
In the procedure ReadDataBC have a statement like:

EDT_Scalebc = msg

After upgrading to WinDev 20 (from v19) I get a

Error at line 47 of Local Procedure ReadDataBC process.
The 'EDT_Scalebc' control is unknown.

----- Technical Information -----

Project : LAB-it

WL call:
Process of 'Local Procedure ReadDataBC' (WIN_LabZ.PROCEDURE.ReadDataBC), line 47, thread 0

What happened?
The 'EDT_Scalebc' control is unknown.

Error code: 1017
Level: fatal error (EL_FATAL)

Dump of the error of 'wd200vm.dll' module (
Identifier of detailed information (.err): 1017
Additional Information:
Local Procedure ReadDataBC (WIN_LabZ.PROCEDURE.ReadDataBC), line 47
EIT_DATEHEURE : 17/06/2015 16:05:40

I can fix this by issuing a

WIN_LabZ.EDT_Scalebc = msg

but then it fails in the next line where I got a call (using the same variable)


That I also can fix by prefixing it with WinLabZ.- But why is this happening now in v20??

The procedure is local to Win_LabZ, and the edit is in the local to win_labz window ?

Is there something that must be switched off in the project pane? (Bugs for example)



Hi Tor-Bjarne,

did you try simply deleting the cpl directory and do a full new recompile?

Best regards

Hi Fabrice,

I found a previous post from you regarding one other project where deleting og cpl dir and all env files + recompile, so I did test this with no luck. (Before original posting)

I also did the following:

1. Project => Other => Repair + compile - No luck
2. Ctrl-X on the Control , then Ctrl-v in the same window +recompile - No luck
3. Move the project to a new folder, reopen, reapply to scm + recompile + repaird - No luck
4. +Some oher actions I cant recall :)

Usually I get a "red-error" (I Think) if a control is used outside it`s scope/ window but there`s none.

There`s a lot of screen fields in the code, and it seems like it going to be a lot of work if I have to prefix every/a lot of the controls with the window name. Is there a way to Re-generate the app from scratch or textfiles or something?

Surely this must be a bug, especially if you are referring to a Local Procedure as your error message suggests?Have you reported it to PCS?

I've purchased WD20 and I'm now seriously concerned about "downgrading" to WD20 if this is the case! :eek:

Hi Darren,

I have a lot of small WD19 projects/apps I`m now in the proccess of upgrading to WD20:

I have a feeling,... not hard proof,.. that there`s something wrong/strange with the Upgrade Project routine (and some small bugs),.

But the App`s that get converted "as-normal", seems a bit faster in execution. So I`m actually happy with WD20, but these "strange things" is a bit frustrating since they happen on already working code.

I Converted a app that hit a GPF on first run, no explanation, no offending code no nothing.
Then I did a tedious debug , step by step:

pc_e is OrgElement

Trace("Line below will eventually kill the app, and "can" make the remainder use 100% of cpu")
pc_e.BackgroundImage = IMG_bg1

s is string
s = "New group"
pc_e.Title = s
pc_e.ToolTip = "Klikk her for å lage ny gruppe"
pc_e.Note = " Lager ny kundegruppe"
pc_e.ID = "-1"

//Here we go...bye bye ... hello gpf
nTopNode2 is int = OrgAdd(ORGA_NoName1,pc_e)
Info("I am not able to catch exception or am I?",ExceptionInfo()) //
