Hello,

I have been seeing a problem error below.
It appears to happen when I click on a listbox.
It does not happen all the time. It happens from time to time
with no logical cause that I can produce with consistency
We use arrays to populate our listbox.
Below is a the code I use with my listbox for the array.

Any help or suggestion with this would be most appreciated.

Thanks
Dave

Code: Select all

olba:bgotop    = { || x := 1 }                                                                                                                                                                                                                                 
olba:bgobottom = { || x := eval( olba:blogiclen ) }

 x := max( 1, min( x, eval( olba:blogiclen ) ) ),;

Thank you for the links on the subject.
Now that I have updated the syntax of my listbox
I would like to get the scrolling characteristics
to be like they were. In my older listbox I am able
roll the scroll bar on the mouse and the have the
selected item in the listbox scroll up and down in
my listbox. Is it possible to do this and if so is there a
good example of how to do it?

Sorry.

Do not understand your question.

Regards.

In our existing application here is an example of our code for the listbox

Code: Select all

 @ 3,8 listbox olba;
  fields prgdispmru(xa,a);
  size 100,100;
  header "MRU-Files";
  of oFldb:aDialogs[ 1 ];
  on dblclick(xfile:=xa[a],winexec("c:\windows\notepad "+xfile))
  a:=1
  olba:bgotop    = { || a := 1 }
  olba:bgobottom = { || a := eval( olba:blogiclen ) }
  olba:bskip     = { | nwant, nold | nold := a, a += nwant,;
  a := max( 1, min( a, eval( olba:blogiclen ) ) ),;
  a - nold }
  olba:blogiclen = { || len( xa ) }
  olba:calias    = "array"

I can rewrite the code this way and it will work

Code: Select all

@  3, 8 LISTBOX olba VAR citem ITEMS xa;
         SIZE 100, 100;
         of oFldb:aDialogs[ 1 ];
         on dblclick(xfile:=xa[olba:getpos()],winexec("c:\windows\notepad "+xfile))

My problem is I am not sure what to do.

It seems that the listbox has gone thru a lot of changes and that my approach
to it's use may antiquated.

In a more complex application here is how we use it

Code: Select all

 @ 12,1 listbox olba;
 fields ctl49700a(xa,a);
 size 480,100;
 header "Segment Data";
 of oFld:aDialogs[ 1 ]
 a:=1
 olba:bgotop    = { || a := 1 }
 olba:bgobottom = { || a := eval( olba:blogiclen ) }
 olba:bskip     = { | nwant, nold | nold := a, a += nwant,;
 a := max( 1, min( a, eval( olba:blogiclen ) ) ),;
 a - nold }
 olba:blogiclen = { || len( xa ) }
 olba:calias    = "array"
 olba:bchange:={|| xinv:=ctl49700f(xsega,a,xtype),;
                    xb:=ctl49700e(xa[a],xst,xds,xss),;
                    b:=1,;
                    olbb:refresh(),;
                    xln:=ctl49700h(a,maxseg),;
                    oxln:refresh(),;  
                    oxinv:refresh() }

 b:=1
 olbb:bgotop    = { || b := 1 }
 olbb:bgobottom = { || b := eval( olbb:blogiclen ) }
 olbb:bskip     = { | nwant, nold | nold := b, b += nwant,;

 olbc:calias    = "array"

 olbc:bchange:={||a:=ctl49700q(xsega,c,xtype),;
                  olba:refresh(),;
                   xinv:=ctl49700f(xsega,a,xtype),;

                   oxln:refresh(),;  
                   oxinv:refresh()  }

I guess the simple question is what can I add to my existing code to correct
the DBCMD/2001 Workarea not in use: ORDKEYNO error?

Thanks

Dave,

I am guessing that sometimes a workarea with an index is selected and other times there is none and thus the error.

The way to test this is to create a small test program and test it with and without a selected workarea.

Of course this should not be a problem since you are using an array, but if it is a problem then the best solution is to fix the listbox class.

Regards,
James

Dave, this way it should work:

Code: Select all

//  Program TESTLBX1.PRG
#include "fivewin.ch"

Function Main()
local oDlg, oLba, prgdispmru:={{"TESTLBX1.PRG"}}, xfile

   DEFINE DIALOG oDlg

   @ 1,1 listbox olba fields prgdispmru[oLba:nAt, 1];
         size 100,50  header "MRU-Files"  of oDlg ;
         on dblclick(xfile:=prgdispmru[oLba:nAt, 1], winexec("c:\windows\notepad "+xfile))
   oLba:SetArray( prgdispmru)
   ACTIVATE DIALOG oDlg
return nil

As you can see in fivewin.ch:
@ <nRow>, <nCol> LISTBOX VAR : is translated to TListBox():New( <nRow>, <nCol> and works with single arrays

@ <nRow>, <nCol> LISTBOX FIELDS : is translated to TWBrowse():New( <nRow>, <nCol>, ...) and works with arrays inside arrays.
HTH & regards

Any progress on this?

I think you could force the error by switching to a new workarea before calling the listbox. This would confirm the cause of the problem.

Euclides and James,

I appreciate your help.

I have modified my code in a fashion that Euclides has posted.
So far so good.

Code: Select all

function testlb2()
local odlg
local xa:=array(2)
local a:=1
local olba
xa[1]:="atest"
xa[2]:="btest"
 DEFINE DIALOG oDlg
@ 0,0 listbox olba;
fields prgdispmru(xa,oLba:nAt);
  size 100,50;
  of odlg;
  on dblclick(msginfo(str(oLba:nAt)))
 oLba:SetArray(xa)
ACTIVATE DIALOG oDlg
return(nil)

I should know soon how well it is working.

Thanks Much
Dave
