Hi Roger
I have this error when I minimize a window and then maximized
having a browse with database

I see that the error states that the alias does not exist as though the database has been closed.

Click on DOT in the error window to open a dot prompt and then observe if the database has been closed.

Hi Roger
Not because the database are closing, if I give the error will break the database and re-run

Hi Roger
Look at these two screen that send

Screen 1 has a Thread: 5 and presents all dbf and Screen 2 maximized when I minimize and then switches to Thread: 1 and does not have the dbf

Thread is like change at some point

This appears to be a problem with threads.

It looks like your window and databases are opened in thread 5 but when your window is minimized and then normalized again, the thread is now thread 1.

Is there a sample program you can give me that displays this behavior?
I will need to be able to compile and run.

Hi Roger
The difference is when I put the bitmap in the bottom of the screen, I think that's what creates the problem.


Paulino Nolberto
Kind regards.

Hi Roger
The problem is this creating this function to change the Bitmap
the bottom of the screen

STATIC FUNCTION ChangeBitmap (oDlg)
DC_PointerWait ()
if VALTYPE (oDlg) = "O"
oDlg: options: = XBP_IMAGE_SCALED
oDlg: SizeRedraw: =. T.
oDlg: bitmap: = DC_GetBitmap (cFondoEmpresa)
oDlg: configure (): InvalidateRect ()
End If
DC_PointerArrow
return ()

I can have another solution?

My guess is that the problem is related to oDlg:configure().

There may be no solution.

Why are you changing the bitmap?

Also, what is the class name of oDlg? It is not an XbpDialog class. Is it a ::DrawingArea ?
There is no :bitmap iVar in the XbpDialog class. I am assuming that it is the drawingArea which is an XbpIWindow class.

Why are you changing the bitmap?

the name of oDlg is: DrawingArea
and I just want to paint on a Bitmap screen

If you remove the :configure(), does the error go away?
