Webcam.au3 > Problem With Windows 7 64Bit

[SYRAU3]

on Win_7 32 Bit version when more than a program uses the webcam a GUI appears :

this is only on 32 bit versions.... But:

on 64 bit this gui always appear in my programs even when i disconnect the program from the device..and run it again.. it appears..

is it wrong with the script? or with the system it self.

Thanks in advance.

can you elaborate on your issue?

have you compiled the script according to the os you have such as x32 bit or x64 bit?

thanks for the reply:

Yes I did, i triet that ,many times.. all people who i send them the compiled program (have win 7 64bit) they have this problem!

I thought that this GUI is appearing because i didn't disconnect the webcam!! but look:

DllCall($user, "int", "SendMessage", "hWnd", $cap[0], "int", $WM_CAP_SET_CALLBACK_FRAME, "int", 0, "int", 0)
 DllCall($user, "int", "SendMessage", "hWnd", $cap[0], "int", $WM_CAP_END, "int", 0, "int", 0)
 DllCall($user, "int", "SendMessage", "hWnd", $cap[0], "int", $WM_CAP_DRIVER_DISCONNECT, "int", 0, "int", 0)
DllClose($avi)
 DllClose($user)

and still appears if you close the program and run it again!..until you restart your system... means what?!

Still nothing?

Can't get it to work on Windows 8 with an integrated Webcam "USB 2.0 UVC HD Webcam".

Same issue as @Syrau3, but it's working on W7x64 with an external Webcam.
