i'm developing web site, 1 of pages it's collection of divs. each div must printed 1 per page. i'm setting width/height of each div this: body .htmltemplate{ height:1140px; padding:0px; margin:auto; width:840px; } it seems work. before 1140px, had 1098px, divs jumped pages, changed 1140px the problem every once in while (let 1 of 6), printpreview shows half (or so) of width, , portion of height goes next page, have double pages print. in example, if have 40 divs, 80 pages. i've noticed when problem occurs, cpu usage in task manager jumps 100% do have idea of causing problem??? missing css attribute (i've tried page-break no luck)??? thanks in advance

i have created custom network handler managing server calls application. internally uses nsurlconnection , callback function block once data fetch complete. current can set callback method or callback codeblock. wanted understand 1 better , why. option 1 : basenetworkhelper * helper = [[basenetworkhelper alloc] initwithurl:@"request/url/as/string" action:@"action/for/request" params:params]; [helper addfinishaction:self sel:@selector(markreadfinished:)]; is way arc warning when call callback method once action complete. bellow. if (_target) { if ([_target respondstoselector:selector]) { [_target performselector:selector withobject:rdata]; } } option 2: basenetworkhelper * helper = [[basenetworkhelper alloc] initwithurl:@"request/url/as/string" action:@"action/for/request" params:params]; [helper startdownload:^(nsdata *data, nserror *error) { // business logic response handling / error h...

i using, arm-linux-gnueabi-gcc compile c programs arm processor in linux. however, not sure default arm mode compiles. for example, c code: test.c unsigned int main() { return 0x1ffff; } arm-linux-gnueabi-gcc -o test test.c now, when @ disassembly of main() function objdump, can see: arm-linux-gnueabi-objdump -d test <main>: push {r7} add r7, sp, #0 movw r3, #65535 ; 0xffff movt r3, #1 mov r0, r3 mov sp, r7 pop {r7} bx lr it appears disassembly thumb mode of arm (because of push instruction). how can display disassembly follows: .sect ".text" .global _fn _fn: movw a1,#65535 movt a1,#1 bx lr or this .sect ".text" .global _fn _fn: ldr a1, con1 bx lr .sect ".text" .align 4 con1: .word 0x1ffff i saw example here: http://e2e.ti.com/support/development_tools/compiler/f/343/t/40580.aspx however, unable view disassembly w...
