multi-user

I have an Eclipse installation on a multi-user Linux system at /opt/eclipse/ . Unfortunately, because of a defect in m2eclipse-mavenarchiver , this plugin uses a folder in a system temporary directory that is common for all users (this manifests as a "permission denied" message for a pom.xml file). I planned to specify a unique value for java.io.tmpdir in a common eclipse.ini based on a user name, but it turned out that it is not possible . One option is to have a per-user installation of Eclipse where each eclipse.ini would have its own value of java.io.tmpdir (e.g., -Djava.io.tmpdir=/tmp

I actually have 2 questions: 1. How might I see who is using my Access database? E.g: There is someone with an Access database opened and it created the .ldb file, I would like to see a list of who opened that database (it could be more than one person). 2. How might I see who is using a linked table? E.g: I have 10 different Access databases, and all of them are using a same linked table. I would like to see who is using that linked table. I don't even know if it's really possible, but I really appreciate your help! For you information: The main problem is that lots of people use the same

Let me explain the title. I'm using Entity Framework Code First in an application (TestApp) . For debugging purposes the TestApp connects to an SQLExpress database (central database server). To keep things simple here, the database contains one table "Products" and the TestApp shows all "Products" from the database in a datagrid and TestApp can add/delete a "Product" or modify the ProductName. public class Product { public int ProductId { get; set; } public string ProductName { get; set; } } public DbSet<Product> Products { get; set; } I have for example 3 pc's where TestApp is installed and

I'm trying to make some MSSQL code also run on MYSQL and I just hit this land mine. Google says the normal approach is to simply do your insert and then select last_insert_ID() to find out what got written. This does not strike me as safe in a multi-user environment, though. There's a narrow window there where another user could insert something and cause a bad return value. How do I safely insert and obtain the key of the inserted record? https://dev.mysql.com/doc/refman/5.5/en/information-functions.html#function_last-insert-id : The ID that was generated is maintained in the server on a per

Does InApp billing (V2 or V3) works for a user who uses several accounts and makes the purchase with an account that isn't the primary one? PD: Some explanation required, no simple Yes/No In App Billing support multiple accounts reported as a bug in code.google , have a look at it According to Mr.Sergej (posted in G+ android dev community) in-app products purchased with the first account won't be active anymore while using multiple user accounts!. InApp billing just charges the user and tells your app whether it was successful or not. It is up to you to figure out how to give the user what

Google has just released Android 4.2, which includes support for multiple user profiles on a single device: http://developer.android.com/about/versions/android-4.2.html#MultipleUsers . Google says that this will be transparent to apps, but I think it could have an impact on the data model used to identify devices, users, and installations. One issue is the use of android_id. The advice on the linked page above suggests identifying a device by one of the methods other then android_id, but I believe that android_id is very widely used for this purpose. My main question is - does each user
