Andrew,
Thanks for your reply, indeed I have to check all this load, unload and
reload stuff, I am on vavacation now and have no acces to the databases.
I do this checks after newyear and come back with the results.
Have a Happy newyear for you and your Family
Fernand

I have been trying to follow what you are doing and I am not sure that
I really understand.
Usually, I have a base document that contains forms. The base document
references a datasource (database) of some sort. I then have my forms
reference that same database. For example:
sub subDisplayForm(sDatabaseName as string, sFormName as string)
dim mArgs(1) as new com.sun.star.beans.PropertyValue
oDatabase = fnGetOpenDatabase(sdatabaseName)
oConnection = oDatabase.getConnection("","")
mArgs(0).name = "OpenMode"
mArgs(0).value = "open" '"openDesign"
mArgs(1).name = "ActiveConnection"
mArgs(1).value = oConnection
oForm = oDatabase.getFormDocuments.getByName(sFormName)
'oForm.visibilityChanged(true)
oForm = oDatabase.getFormDocuments.loadComponentFromURL(sFormName,
"_blank", 0, mArgs())
end sub
In this example, the connection is obtained from the database document
so everything points to the database associated with the ODB document.
I use those specific terms in case the real database is an external
database such as MySQL.
Are you attempting to use a connection that points to a different
database?
Now, I will take a look at what you have:

lets starts with geting a connection (here I make a connection to a
odbc driver whos gives me acces to a MS SQL database)
sURL = "sdbc:odbc:debiteuren"
oManager = CreateUnoService("com.sun.star.sdbc.DriverManager")
oCon = oManager.getConnection(sURL)
OK, so here, you clearly reference an external DB, one that is not
even referenced by a Base document. No problem so far.
I have one native OO-basedocument with 2 Formdocs who uses the same
internal HSQL databse engine
the goal is to use Switchboard to give users acces to all my forms
and keep them away from the databsestuff
You have a Base document that contains data. I assume that the schema
in the Base document is the same as the external database.
in Formdoc1 I have oForm who is the mainform for some Subforms who
must/can use my "oCon"
in FormDoc2 I have oFom2 as a mainform who also must use my "oCon"
We can not uses "oCon" to set a ActiveConnection in a already opened
form.
oForm.ActiveConnection = oCon >>>>>gives a error (propertyVeto....)
First we have to open a form with "loadComponentFromURL" who accept
oCon as argument.
Now I have a "open" oform with right "ActiveConnection" but the
subforms are not knowing about this connection. The good news is
that we can pass the "ActiveConnection" to the subforms
oSubForm.ActiveConnection = oForm.ActiveConnection
be carfull to check that the form is not opened in "designMode" the
trick is only working when opened in "open" mode !!!
Let me repeat what you wrote to verify that I understand.
(1) You can use your external connection to load a form and the
connection works as desired.
(2) The subforms do not use the external connection as desired, but
you are able to directly set the sub forms to use the same connection
as their parent.
BUT !!!!!it is tnot possible to passing my "oCon" to the other
oform2 who is located in a other fromdocument
oform2.activeConnection = oform.activeConnection >>>>>gives a error
(propertyVeto....)
Now, you state that you can not change the connection on a main form
if the form is already open.
Do you know who vetos the exception? Is it the DocumentDefinition?
Does the form have a "reload" method?
What happens if you call unload before setting the active connection
and then calling load? How about calling reload then setting the
active connection? Have you tried closing the connection that is used
and then setting a new active connection?
These are all guesses, and you might have better luck asking on the
dba forums (unless Frank hangs out here).
