Finally i found out that it was MS Application Verifier breakpoint, perhaps it indicates error in PB. After disabling verifier application works fine.

EnableExplicit

Delay(5000)
End

OpenFile(#PB_Any, "bla-bla")

So the problem is that callbacks crash program on MacOSX both x64 and x86.

That's why i call it strange, it happens only on one particular system.
And you're calling it a PB bug?

If i remove OpenFile line(which is not even executed) - it works, if i rename exe - it works. Also i don't have any issues with all other software and tools. So I'm pretty sure that it is not ...

Wolfram wrote:You must send a PostEvent() to the MainWindow loop and open it from there.
Don't do any GUI operations directly inside a thread.

That's what i did as a quick fix, but it blocks event loop and i have to create my own PathRequester that does not block... which is not fine.

Compiled with threadsafe and unicode, 5.31 x86:

Code: Select all

End

OpenFile(#PB_Any, "bla-bla")

On particular system program crashes 10 of 10 times if it has name "ArchiveManagerHelper.exe", if i rename program (to "ArchiveManagerHelper1.exe" for example) it works fine.

Using PathRequester from thread, fisrt time it works, second time program crashes. Purebasic 5.31 x86 and x64, MacOSX 10.9.5. If i call PathRequester from main thread it works fine.

thanks, finally i've made it work, but PB is still very confusing to me.

Code: Select all

ProcedureCDLL initializer(extData.l, *ctxInitializer.Long, *ctxFinalizer.Long)
  *ctxInitializer\l = @contextInitializer()
  *ctxFinalizer\l = @contextFinalizer()
EndProcedure

Hi,
I'm trying to use PB to create extension for Adobe Air (it's a dll),
i've already created similar extensions using C language, but run into issues with PB.

The problem is that functions (contextInitializer and contextFinilizer) passed to runtime are never called

FlashRuntimeExtensions.h ...

hi, thanks for the library, but probably there is a bug:
1. HID_Lib_DeviceTest is 1 means ok
2. HID_Lib_OpenDevice is 0 means failure (by the way GetLastError_() returns 0)

my device is custom usb mouse.

I think this can help:

Why do I receive "Access denied" when attempting to access my HID ...
