image scanner - Twain detect landscape for scanning -

i writing programme images twain device. problem when set mode landscape scanner gui not program, cannot observe , image rotated wrong. if understand spec right icap_orientation should homecoming if landscape or portrait or different rotation. 1 scanner seek on returns twor_rot180 whether set landscape or portrait. different scanner twor_rot90 think sending right code it. understand wrong or doing else wrong? there different way observe landscape? thanks.

i figured out getting capability icap_orientation wrong way, sending me wrong info before making changes.

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? -

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? - what difference between "some" == "some\0" , strcmp("some","some\0") in c++? why if("some" == "some\0") returns false , if(!strcmp("some","some\0")) returns true ? see next diagram. shows 2 strings in memory, content in box, beside box you'll see address of each one. when you're doing if("some" == "some\0") comparing addresses. translated if (0xdeadbeef == 0x0badcafe) false. when utilize strcmp , compare content of each box until reach \0 in each of them. that's why sec test returns true. if alter first test if("some" == "some") compiler may potentially see same strings , store them once. means test transform if (0x0badcafe == 0x0badcafe) true. c++ string comparison

actionscript 3 - Flex: moving a point with rotation doesnt change the point XY? -

actionscript 3 - Flex: moving a point with rotation doesnt change the point XY? - i have follow issue : i have point setted @ border on component, changed transform point center of component in order match component rotation. the of import part when seek point xy after rotation - remains same before rotation. how xy, after rotation ( changeing point.rotation property specific degrees of rotaion ) if want point after rotation, cos(r) * x, sin(r) * y easiest way. if want point after transformations, should able utilize displayobject.transform.transformpoint(x, y) . there's displayobject.localtoglobal . in case phone call localtoglobal(x, y) , localtoglobal(0, 0) , calculate difference. see transform livedocs , displayobject livedocs flex actionscript-3
