i looking script in powershell or vb check current pc verify member of specified sccm 2012 collection. we want can create multiple deployment types , assign them different collections, use deployment type requirements make sure deployment types deploy correct collection. not want create multiple applications same media when there slight variations in installation parameters. i believe there should basic script check if current pc member of collection dr100038 (as example) , return 1 or 0. with colleague, had luck following (powershell , wmi inside), sccm not providing @ moment right commandlets : for device, id: $deviceid=(get-wmiobject -computername -namespace root\sms\ -class sms_r_system -filter "name=''").resourceid search collections linked : get-wmiobject -computername -namespace root\sms\ -class sms_collectionmember_a -filter "resourceid='$deviceid'" filter resulting list i found solution, digging in https://s...

my app requires characters except can customized. possible have 1 image view change actual image else? here example: there item 1 , item 2. item 1 default. if click buy item 2, image view of showing item 1 replaced picture of item 2. is there way can , if not how developers have customization that? unless missing something, seems simple as: uiimageview *myimg = [[uiimageview alloc] initwithimage:[uiimage imagenamed:@"myfirstimage"]]; and if want change image myotherimage , can set below [myimg setimage:[uiimage imagenamed:@"myotherimage"]]; if need image component, subclass uiimageview , call functions swap between images.

just getting started in excel , working database extract need count values if items in column unique. so- below starting point: =sumproduct(countif(c3:c94735,{"sharable content object reference model 1.2","authored scorm/aicc content","authored external web content"})) what i'd figure out syntax this- =sumproduct (countif range1 criteria..., range2 criteria="is unique value") am getting right? syntax bit confusing, , i'm not sure i've chosen right functions task. i had solve same problem week ago. this method works when can't sort on grouping column (j in case). if can keep data sorted, @miked 's solution scale better. firstly, know frequency trick counting unique numbers? frequency designed create histograms. takes 2 arrays, 'data' , 'bins'. sorts 'bins', creates output array that's 1 longer 'bins'. takes each value in 'data' , determines bin belongs ...

i've done these problems, not looking straight answer. looking guidance on whether or not doing correctly , if not, possibly explanation on why incorrect. :) so have these 2 problems. i've commented logic in why got answers. if please verify doing correctly? public static integer findtripleb(int[] anarray) { //method variable: n if (anarray.length <= 2) { return false; } //time complexity: 1 // use insertion sort sort anarray (int = 1; < anarray.length; i++) {//tc 1+(n+1)+n // insert anarray[i] int j = i-1; //tc 1 int element=anarray[i]; //tc 1 while (j >= 0 && anarray[j] > element) {//tc log(n) anarray[j+1] = anarray[j]; //tc 1 j--; //tc 1 } anarray[j+1] = element; //tc 1 } //total tc: (2n+2)(1+1+log(n)(2)) = (2n+2)(2+2log(n)) = 4n+(2log(n))(2n)+4+4log(n) // check whether anarray contains 3 conse...
