Tracy, Tried that... no joy.

My code is a little misleading as I meant to say: Slight mis-information in the last post in that:

"Unknown OCOLLECTION_X - Undefined The collection is mainly used in the "myRefresh" event of the component (base class is a container) and is initialised to null on the property sheet, subsequently getting populated in the actual <<container>>.Control_Source_Assign method"

Should be read as " .... <<container>>.oCollection_Assign method".

I use a user defined property Control_Source to bind the collection to the object in a similar way to the native ControlSource property.

This is now baffling me completely.

Gentlemen, I have a VCX library which we have developed that uses collections and I

keep getting a compilation error:

Visual Class Library d:\dev\flexipol\flexispec\classes\traffic_light.vcx

has the following errors:

 Unknown OCOLLECTION_X - Undefined  The collection is mainly used 

in the "myRefresh" event of the component

(base class is a container) and is initialised to null on the property sheet, subsequently getting populated in the actual <<container>>.oCollection_Assign method::

• ControlSource_Assign Method

Lparameters vNewVal Local oCollection_1 As Collection Local I

This.oCollection = Evaluate(vNewVal) This.Control_Source = m.vNewVal oCollection_1 = This.oCollection ... etc.

The collection thus assigned is manipulated in the myRefresh method and

basically parsed through element by element refreshing a discrete control for every instance in the collection.

• myRefresh Method

Local oCollection_x as Collection local I local oLight Local lDoTextMerge local cOldAlias

cOldAlias = Alias() oCollection_x = This.oCollection

I=1 For Each oObj In oCollection_x ... etc etc.

All the coding works despite this damned error being thrown at compile

time and I have tried all types of External commands thinking that the oCollection not being found could be fixed as you do with external arrays. However there isn't an "External Collection" command... so I am now stuck!

Any ideas?

Dave

Dave,

Backup, then pack the VCX. Sounds like you have a lost/corrupt code bit.

Ted, Yes, that was the first thing I tried.... no effect...

I have also tried declaring oCollection_X as a public variable in the mainline stub even though it is never called just to remind the compiler that it does exist... again no joy I am afraid.

I'd use:

EXTERNAL ARRAY oCollection_X

in the myRefresh() code

But it sounds like you've tried that. Each method in a VCX is essentially compiled separately, so the EXTERNAL command is local to each snippet.
