how can I get a larger stack trace from a node.js network error? -

I get this error: error: accept amphiel at fault (net. Js: 769: 11) On TCP. Connection (NET JS: 1017: 24) Can I get a line number of my code from a node. Js app that calls the TCP.conconvention in the first place is? No you can not, because your code is TCP. No connection . This is an event handler, so an event triggering it is one of the reasons because it is difficult to debug event-based programming. I think that you will see some luck, though that error means, though. Some searches suggest that you are killing a file descriptor limit, which may increase (but it will be OS based, so I can not tell you how without much information).

windows - Is there a way to check for redirection inside a batch file? -

If we have a batch file that redirects to a log like this: C: \ test \ example.bat> C: \ tasting \ example.log There is no way within the batch file to determine whether a logout file has standard output redirects? Actually the batch file I need three arguments with it. When the argument is left out, the batch file prints an example of an example, such as regular doss commands, and 'pauses' throws out So that the instructions can be read. Although the batch is called without any argument and it is being logged, then the batch file will always sit there for the key to break a break but will not show anything on the screen. Normally it will not be a problem at all, although I am trying to make this stupid proof because I will not be able to implement the batch file in other script / scheduled works. At this point it seems that I have to stop using it altogether, but I was hoping for the solution where I had not to. Thank you for the help. I have no way to ...

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 [...

ruby - Rails vestal_versions gem create versions without saving parent -

I'm interested in using vestal_versions gem in my rail app, but I'm wondering if anyone knows that anyone The way I can create a new version but can not actually update the associated ActiveRecord. For example, if I have a user with the first name "jim", and I want to be able to continue the version without a new version of "Steve", I change the original record until I Revert_to! (Newer_version) or something like this) If it is not made gem, any clue where should I start the bar? After checking the behavior of this gem, I found that it is nothing like that In fact to really have been established. You can force this behavior with something: def create_version merge_version_changes create_version end a 'variant' model With the changes that have been modified in your Live ActiveRecord without any parent object tables: blah = blah.first blah.version will tell you that you are using the latest version, but do not load that data (s...

ios - Random white flash in phonegap app -

I have an app created with phonegap and jazzery mobile which runs between multiple multiuser jazz mobile documents. It works well for the work I want, but the odd thing is that sometimes I get a white flash when I go between different HTML files. Now I have seen that this is a common issue, while using JQM and Phonegap, but all the other posts I have seen but there is no other solution than getting rid of page transition? Has this problem been resolved in PhoneGap 2.5? I use Jquery Mobile 1.3, Jquery 1.9, and Phonegap 2.4 something Well documented for this I had a similar problem recently, you can either set page transition to 'None': This eliminates all the issues of flicker. You can also try to add it: .ui-page {-webkit-backface-visibility: hidden; } For your CSS, this is not a correct fix, and causes severe instability for me.

powershell - Checking for null arrays in an PSObject -

How do I check for an object or empty, which has multiple arrays? $ Buildings.north = {bld1, bld2, bld3} $ buildings.South = {} $ buildings.East = {bld5, bld6} $ buildings.West = {bld7, bld8, bld9 $ Buildings , Bld10} I started with if / elseif to go through each, but it would be 16 combinations: if ($ buildings North Coat ount-AQ "0" - and $ Building.

vb.net - Match a string variable to the location in data file(specified column) so I can use all values in that row VB? -

The row that corresponds with, I want to assign the variables to the rest of the values ​​for that column. I've tried to find the match that I think: String as an integer for every straw in the dim intIndex (1) if Str.Contains (strID ) Then intIndex = Str INDexOf (strID, 0) end if next Even once I get the matching line number, how do I tell each variable, the row and column Ask to assign yourself? The sample of one line and each column is divided by ",": 1234567,03 / 02 / 20137,2, B, L, ST and has unlimited rows Go here - assuming that you already have an array of strings (probably readAllLines ), something like this should run in the right direction: Boolean as a rigid line = Incorrect dim row number as integer = 0 dim columns like str String (string) = "" like dim col1 "string =" "as a dim col2 string =" "string =" as dim col3 = "" "String = 7" as a stroke while the rowfound and not the row...
