ef migrations not automatically detect complex changes, created empty migration , made changes hand up() , down() . updated database, , worked in both forward , reverse directions. but later, when made more changes , created new migration, it automatically added kinds of changes not needed - handled them manually in previous migration . i know can delete migrations , start scratch, that'll create far many problems, don't want that. how fix this? you can establish new baseline if don't have prior released databases out there. delete old migrations run: add-migration mybaseline –ignorechanges update-database now model , database in sync , can make model changes , create new migrations. turn automigrations on until ready deploy roll them single migration can script out clients. https://msdn.microsoft.com/en-us/data/dn579398.aspx#step3

consider 3 ways assign value: #!/bin/bash a=1 let a=1 ((a=1)) are 3 assignments totally equal? if shell has non-posix extensions (ie. ksh or bash), they're entirely equivalent: a=1 string assignment, whereas let a=1 , (( a=1 )) numeric assignments, gets stored in a string representing number 1 in every case. $(( )) posix-compliant way create math context. (( )) , let , contrast, not specified posix, extensions available in shells go beyond standard. now, consider instead: b=2 # result | posix? | type | comments # --------+---------+--------------------+---------------- a=b # a=b | true | string assignment | let a=b # a=2 | false | numeric assignment | ancient non-posix syntax a=$((b)) # a=2 | true | numeric assignment | modern posix syntax ((a=b)) # a=2 | false | numeric assignment | modern non-posix extension

i didn't want dragged change size. i'm primary learner. create part in application.e4xmi. the structure 'window , dialogs ---> trimmed window ----> controls ----> part', created class associate it. if have 1 part in trimmed window can set style of window prevent resizing. you setting styleoverride value in 'persisted state' section on 'supplementary' tab of 'trimmed window' page in application.e4xmi. add persisted state value key of 'styleoverride' , value of '96' corresponds 'swt.close | swt.title' style.

how can write algorithm can take unused id's out of sequence starting 1 99 in format "c00"? example newid(['c01', 'c02', 'c03']) should emit 'c04', newid(['c02', 'c03', 'c04']) should emit c01, , newid(['c01', 'c03', 'c04']) should result in c02. i wrote implementation result wrong. example : cat_id : c01, c02, c05, c06, c11. when run it, expected result c03. algorithm follows: sort id asc go through every item in list compare first value next, if not same, add 1 , exit loop. this code: public static string get_areaid_auto() { string result = ""; if (db.tests.tolist().count <= 0) { result = "01"; } else { int maxid = 0; foreach (var item in db.tests.orderby(e => e.cat_id).tolist()) { if (int.parse(item.cat_id.substring(1)) + 1 != int.parse(item.cat_id.substring(1))) ...
