visual studio - Pass msbuild properties to devenv.exe on the command line -

i building solution automatically devenv.exe on our ci server, works totally fine. deployment purposes added nuget package (namely octopack). documentation tells me pass properties msbuild when building, using devenv, not possible. through research, learned can add propertygroup the .csproj of project, add these properties. prefer not that, need replace values (like version number) in properties, not want put placeholders strings. additionally, need able have propertygroups active when building on ci server, not when developing , building locally. this leads question: can somehow pass properties, passed msbuild (via /p: ), devenv on command line? (i'm posting answer question can closed out). i'd suggest not using devenv.exe. start using msbuild.exe. pass in parameters using /property:name=value /p:name=value use nuget.exe restore mysolution.sln restore packages.

c++ - Fast data structure or algorithm to find mean of each pixel in a stack of images -

i have stack of images in want calculate mean of each pixel down stack. for example, let (x_n,y_n) (x,y) pixel in nth image. thus, mean of pixel (x,y) 3 images in image stack is: mean-of-(x,y) = (1/3) * ((x_1,y_1) + (x_2,y_2) + (x_3,y_3)) my first thought load pixel intensities each image data structure single linear buffer so: |all pixels image 1| pixels image 2| pixels image 3| to find sum of pixel down image stack, perform series of nested loops so: for(int col=0; col<img_cols; col++) { for(int row=0; row<img_rows; row++) { for(int img=0; img<num_of_images; img++) { sum_of_px += px_buffer[(img*img_rows*img_cols)+col*img_rows+row]; } } } basically img*img_rows*img_cols gives buffer element of first pixel in nth image , col*img_rows+row gives (x,y) pixel want find each n image in stack. is there data structure or algorithm me sum pixel intensities down image stack faster , more organized current impleme...

Understanding android navigation drawer and fragments -

i'm quite new drawer material , have trouble understanding things: need create activity fragment on it. different selections on drawer must replace current fragment one, drawer in fragment or 1 activity itself. more drawer living in fragment , if not possible create in fragment . asking cause see when initiating drawer need fill parent activity. when tried use navigation drawer template in android studio didn't had use fragment checkbox. there many ways achieve want. think simplest way is: 1) drawerlayout view should reside in activity (probably base layout). 2) when click on item in draw 2 things happen: the fragment replaced (you have 1 layout contain fragment , replace fragment in it). the items inside drawer update (if making list set data , call notifydatasetchanged() . don't forget save state can recover in case activity recreated.
