Running out of Windows Handles.
Posted: Wed Nov 02, 2022 05:07 PM

I got an error and my app just terminates with the following error message in the Error.log file:

System Error: The current process has used all of its system allowance of handles for Window Manager objects.

This is because of a TSay object (actually several, around 12). which are called from a timer in the program.

The program is basically like an arrivals display at an airport. I was creating the Say object without referencing a variable.

I changed it to create the say object with oSay01 through oSay12 and set them to nil every time they are called.

Still got the same error. Is there a way to recapture the handles so this stops happening?

Thanks,

Thanks,

Hi,

Use:

Code (fw): Select all Collapse

GetGdiObjects()
GetUserObjects()
GetGdiObjectsPeak()
GetUserObjectsPeak()

Dear Byron,

Don't create TSay objects. Use oWindow:Say( ... ) method for a window or dialog

In Fivewin 21.11 I get link errors on each of the functions

Error: Unresolved external:

_HB_FUN_GetGdiObjects

_HB_FUN_GetUserObjects

_HB_FUN_GetGdiObjectsPeak

_HB_FUN_GetUserObjectsPeak

do I need a specific lib for these?

Thanks,

Once you created the Say objects Say01 tp Say12, do not create them again, Keep setting new values to the same Says.
