Hi,
I have tried to use ON CHANGE
I have put all the tab init in each a function and tried
I have put some Qout to see what happens

The

Here is the source of the concerned part of my tool:

//
============================================================================
Function ReadReg()
//
============================================================================
Local aCom:={}, maxi:=.f., cMessage
Local oDlg, oFont := HFont():Add( "Serif",0,-13 )
Local cTitle := "Ouverture d'un registre"
Local cText01 := "Choisissez la commune"
Local cText02 := "Choisissez le type de registre"
Local cText03 := "Choisissez le registre"
Local cCommune:="", cType:="", cRegistre:="", lBox:=.t.

// init of tabs
SearchCommune()
Qout("Communes  " +str(len(aCommunes)))
SearchType(aCommunes[1])
Qout("Types     " +str(len(aTypes)))
SearchRegistre(aCommunes[1],aTypes[1])
Qout("Registres "
+str(len(aRegistres))+chr(10)+"------------------------------------------"+chr(10))

// Here is what is output:
// aCommunes[1] Chalais
// Communes          30
// Chalais :
// aTypes[1] Décès
// Types              3
// Chalais/Décès :
// aRegistres[1] CHALEIX_DECES_1803-1812.PDF
// Registres         10
// ------------------------------------------
// All is right

if len(aCommunes)>0 .and. len(aTypes)>0 .and. len(aRegistres)>0
   lBox=.f.

// With on change I expected to update the tab and the next combobox
//
// Chalais :
// aTypes[1] Décès
//
// but i nok
// if I do it again:
//
// Jumilhac-le-Grand :
// aTypes[1] BMS
//
// What is wrong:
//
// - The value of the tab is changed on next 'ON CHANGE' call
// - The content of the combobox is never updated.
//
// This for all the concerned combobox
//
// Have you an idea of the reason of seach problems ?
// I have tried ON INIT, but it fails (syntax error)
// How to refresh tabs and combobox ?
