c# - How to use Windows Runtime classes in .NET Core libraries? -


i'm developing library use wpf , windows 10. i'm running issues getting compile on latter. here of code:

project.json

{     "frameworks": {         "net46": {             "frameworkassemblies": {                 "windowsbase": "4.0.0.0"             }         },         "netcore50": {             "dependencies": {                 "microsoft.netcore.universalwindowsplatform": "5.0.0"             }         }     } }

dependency.cs

using system; using system.collections.generic; #if net46 using system.windows; // .net framework 4.6 #elif netcore50 using windows.ui.xaml; // windows 10 apps #endif  public static class dependency {     public static dependencyproperty register<t, towner>(string name, propertychangedcallback<t, towner> callback)         towner : dependencyobject     {         // code here....     } }

while compiles fine net46 (which traditional .net framework), i'm having trouble getting work netcore50 (which can used windows 10 apps). reason, looks types dependencyproperty or dependencyobject not included in configuration.

is there netcore50-compatible nuget package can install contains these types, can use them library?

thanks helping.

edit: typed in dependencyproperty in vs , hit f12. appears type lives in windows.foundation.universalapicontract assembly, there's no such package on nuget.

finally solved problem on own! (if you're looking quick answer, may want scroll down.)

i remembered chance .net core github repo had bunch of winrt-specific libraries, system.runtime.windowsruntime. so, headed on there see how did it.

it appears use kind of internally-hosted "targeting pack", contains single windows.winmd file (which holds types in windows runtime), achieve affect. unfortunately, package hosted on private nuget feed meant .net core team, can't use it.

i've opened issue on corefx repo here, can petition microsoft official solution problem. in meantime, i've taken matters own hands. i've found different versions of windows.winmd on laptop, , uploaded them nuget packages. here are:

you can use them this:

"frameworks": {     ".netportable,version=v4.5,profile=profile32": {         "dependencies": {             "target.windowsruntime": "8.1.2"         }     } }

after that, you'll able write this:

using windows.ui.xaml; using windows.ui.xaml.controls;  public class myapp : application {     public myapp()     {         var button = new button();         button.content = "hello, world!";     } }

and it'll work.

java - pagination of xlsx file to XSSFworkbook using apache POI -

right in code, reading xlsx file, xssfworkbook, , writing database. but, when size of xlsx file increases, causes outofmemory error. can not increase server size, or divide xlsx file pieces. tried loading workbook using file (instead of inputstream), didn't either. i looking way read 10k rows @ time (instead of entire file @ once) , iteratively write workbook , database. is there way apache poi? poi contains called "eventmodel" designed purpose. it's mentioned in faq : the ss eventmodel package api reading excel files without loading whole spreadsheet memory. require more knowledge on part of user, reduces memory consumption more tenfold. based on awt event model in combination sax. if need read-only access, best way it. however, may want double check first if issue somewhere else. check out this item : i think poi using memory! can do? 1 comes quite lot, reason isn't might think. so, first thing check - what's source of prob...

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
