While reading from a Sqlite database (500000 records)
my program updates 3 StringGadget, containing the
number of the record and other stuff.

Nothing appears in StringGadget but the last value.
Also if I modify my program in order to show me 1 value every 100 record readings.

The only effort program seems to be able to make
is managing database: only at the end it updates
my StringGadget (only last value, of course)

Can someone hint me anything?

If you want your stringgadget to be updated, you have to handle the events. Note that it will slow down your loop.

Quick example :

Code: Select all

If OpenWindow(0, 450, 200, 400, 125, "Example", #PB_Window_SystemMenu|#PB_Window_SizeGadget|#PB_Window_MinimizeGadget|#PB_Window_TitleBar)
  StringGadget(0, 32, 31, 344, 27, "0")
EndIf
;
For I = 0 To 10000
  SetGadgetText(0, Str(I))
  ; Try with and without this line
  While WindowEvent() : Wend  
  ;
Next
;
Repeat
  If WaitWindowEvent() = #PB_Event_CloseWindow
    Break
  EndIf
ForEver

Ah ok, now it works, many thanks.

Progress bar gadget was working without managing any event, I thought StringGadget too.
