  • uninitialized constant MysqlCompat::MysqlRes (using mms2r gem)

    - by William
    Hi, moved a rails app of mine onto a new server and had to install a few gem dependencies. However, after installing the mysql gem I get the error, uninitialized constant MysqlCompat::MysqlRes, whenever I try to run a rake command that involves the mysql database. It seems I only get this error when I require the mms2r gem. Has anyone ever heard of this? I'm running mysql 2.8.1 gem.

  • How to seperate the model from the view?

    - by geejay
    I have a bunch of model objects. These objects end up being rendered as views (say forms) in a rich client app. I started to annotate the fields in the model objects (Java annotations) with things that let me render them as forms on the fly (e.g displayname, group, page, validvalues). I now realise that the view has crept into the model. How should I seperate the view logic out of the model objects? TECH: Java, Java Annotations, Eclipse RCP

  • DLL configuration file in asp.net site

    - by Tominator
    Hi, I've made a .net 2.0 librabry project, that results in a dll. I've made an app.config file in my project, with settings used in the dll, with the intention that they can be changed later. I'm attempting to use the dll in an asp.net web application now, so I made the reference to my other project's output, and I see that the dll is copied over to the site's bin folder, and everything works. However, the configuration file is not copied. When I manually copy the app.config and rename it to myDll.config, it has no influence. The contents of the config file is approximately this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" > <section name="myDLL.My.MySettings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> </sectionGroup> </configSections> <applicationSettings> <myDLL.My.MySettings> <setting name="myDLL_webservice_Service" serializeAs="String"> <value>https://myhost/Service.asmx</value> </setting> <setting name="ID" serializeAs="String"> <value>6</value> </setting> </myDLL.My.MySettings> </applicationSettings> </configuration> And I use its settings in the dll with this (vb.net code): Private _id As Long = My.Settings.ID How can I put my config information somewhere so it can be used? In the web.config of the site application? That has only the appSettings section, and it uses the syntax. It doesn't appear to work though. In a custom file format that I create and use? Not that pretty..

    A java app runs with the following flag: -XX:+PrintSafepointStatistics, and then produces the following line on the standard output console: 2 VM operations coalesced during safepoint Anyone cares to explain what this mean ?

  • How to detect if Safari is disabled on iPhone

    - by zorro2b
    How can you detect whether Safari has been disabled by parental controls on the iPhone? I know it is possible because the App X3Watch refuses to work until Safari is disabled. As far as I can see there is no api for the parental controls, so what technique can be used for this?

  • MvvmCross experiences, hindsight, limitations?

    - by Jason Steele
    I am considering using the MvvmCross framework for a cross platform mobile application that will target Android, iPhone and WP7. Does anyone have any experience with this framework they would like to share, and are they aware of any constraints or limitations that it would be useful to be aware of? For example, am I still able to use native page transitions of my choosing? Are there any performance or storage (app size) implications?

  • Best way to check for string in comma-delimited list with .NET?

    - by Jeremy Stein
    I'm reading a comma-delimited list of strings from a config file. I need to check whether another string is in that list. For example: "apple,banana,cheese" If I check for "apple" I should find it, but if I check for "app" I should not. What's the most straight-forward and concise way to do this? It doesn't have to be fast. (I'll add my solution as an answer, but I'm hoping someone has something better.)

    With respect to an application that has both a web and desktop client version: What is the best practice for the desktop client which needs access to a SQL Server?

What type of scope would call for one vs the other (enterprise intranet vs. web app, etc) Are there any other considerations that are necessary when choosing on platform?
