PB7.0.3

hi,

i would like to create a custom userObject uo_myDW that inherits from
DataWindow and stuff some default behaviour into it.

For a new app i'm writing, i need a pile of input windows, all sharing the
same functionality. I'd like to build uo_myDW so that in incorporates all
standard 'inputDW-behaviour'.

Here 's what i want to do
For one of these functionalities mentioned above, i need the collection of
uo_myDW's columns that are 'Tab-able' (have a tabindex > 0), and store them
in a instance var ids_DWColumns for future reference.

SO i need to obtain the properties of the dataobject assigned to uo_myDW

what i do is...
>I create an instance of uo_myDW
>i set the instance's dataobject and transobject
>then i call uo_myDW::ue_getDWCols() to obtain all columns that have a
tabindex > 0
    the logic looks like

        // obtain the nmber of cols
        li_cols = Integer( this.Describe("DataWindow.Column.Count") )
        --> returns nothing!
        --> if i use li_cols = Integer(
this.Object.DataWindow.Column.Count ) PB says me "Null object
reference"

        // loop through cols and store the ones with tabindex > 0 in
ids_DCWolums
        FOR li_col = 1 TO li_cols
         ls_colName  =  Describe("#" + String(li_col)+".Name")
         li_tab    =  Integer( Describe("#" +
String(li_col)+".TabSequence") )
         IF li_tab > 0 THEN
              li_newrow = ids_DWColumns.insertrow(0)
              ids_DWColumns.object.colname[ li_newrow ] = ls_colname
              ids_DWColumns.object.colnum[ li_newrow ] = li_col
              ids_DWColumns.object.coltab[ li_newrow ]   = li_tab
         END IF
        NEXT

        // Sort ids_DWColumns on ascending tabindex
        ids_DWColumns.setsort( "coltab A" )
        ids_DWColumns.sort()

Hi,

I would check if the setting of the
dataObject is correct. Also you can
check if setTransObject(...) returns 1.

chris,

I check the name of the dataobject just before performing the Describe (the
name is correct).

The SetTransObject fails! As a matter of fact, it fails for every DW or DS i
use on my main window, but i only just now notice... All retrieves and
updates are perfectly OK on the other DW's???

i cannot see why the settransobject would fail?

Hi,

I'm not sure but maybe you see
the reason why setTransObject(sqlca)
fails in sqlca.sqlErrText:

if dw_1.setTransObject(sqlca) <> 1 then
    messageBox("DB Error", sqlca.sqlErrText)
end if

Maybe your application is not connected
to a database in this moment?

chris,

Just ignore my earlier post!


I check the name of the dataobject just before performing the Describe (the
name is correct).

The SetTransObject fails only for my uo_myDW!

I cannot see why the settransobject fails, when it succeeds for other DW's
and DS's on my main window where i use exactly the same transaction object.

Hi,

try to retrieve the datawindow from the IDE. works?
Then check if the library containing the datawindow
is in your libpath. yes?
Then check if there are multiple datawindows with the
same name in other libraries. No?

Double check the dataobject name, because for the
moment I have no further idea.

is OK

I guess this is where i need to look for my problem.

The situation is this...
On my main window, i have a large DW named dw_productPrices ( of type DW )
What i want to do now, is change the dw_productPrices to type uo_myDW.
I would like to retain the name dw_productprices because if i change it, i
need to change it all over my app.
i guess i am missing something here.

What i did is...
I renamed the old DW_productPrices ( of type DW ) and replaced it with my
new DW_productPrices ( of type uo_muDW ). Of course, in this case i
explicitely need to call dw_productPrices = CREATE uo_muDW.
Then PB gives me a compile error saying there allready exists an object
called dw_productPrices.

Do i need to make my dw_productPrices an instance var on my window, or ...?

Chris,

i removed the dw_productPrices = CREATE uo_myDW
and the settransObject is successful, also the describe!

I guess i need to take a look at the inheritance chapter ;-)

thanx 4 your time!

Hi,

a dw on a window is a control, you never
need to call <controlname> = CREATE <controltype>,
because the controls are created by
PB.

What you want is to change the type of
an already placed control. There are two
ways:

1.) Delete the existing control from the
     window an place a new one there.
     Because the new one inherit's from a
     userObject (wich inherit's from a dw),
     you have to place a userobject and
     not a dw on your window. Of course,
     you will loose alle scripts in window.dw_productprices.
     If this is critical, then choose option 2:

2.) Export the window (in library painter
     select the window an choose "Export".
     Edit the resulting text file. Search for the
     string

          datawindow dw_productprices

     and replace it with

          uo_muDW dw_productprices

     Then import the window. Be sure to
      have a backup of your window!

But all this don't explain your initial problems,
because the dataobject don't changed.
