c# - Writing code that can work with multiple database objects -

-

I basically have two different databases, which have different tables in them but in both of them "Table1" is the exact same structure. var db = new ???; If (mode == "output") {db = new database 1 ("connection string for database 1"); } Else {db = new Database2 ("connection string for database 2"); } Var result = db. Table1.Where (a => a.Value == 1). first ();

How can I do the above mentioned work, so I "result" from two different databases (based on "mode") without writing two different definitions for "results" "Can I specify?

Store the connection string separately in your config file. You can then swap the connection string on the runtime to point to the database object in the correct database: 

  if (mode == "PRODUCTION") {db = new database (configurationManager.ConnectionStrings [ "Production-key"]); } And {db = new database (configuration manager connection connection ["dev-key"]); }

After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job.

NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
