  • Reasons to store users' data in LDAP instead of RDBMS

    - by Ancymon
    It is often said that using LDAP is a good way to store data about users. That's beacause users' "directory" is hierarchical and it changes rarely. But in my opinion that doesn't exclude using RDBMS. What might be reasons to use LDAP? I guess that storing multi-valued fields or adding custom fields in LDAP might be easier but it can be done in database too (unless you have many records)

    Hi Al, I have a simple navigation based app which has a bunch fo forms in it, I have a method connected to a button that saves data when the button is tapped but I was wondering if I could call the same method when the back button is tapped in the navigation?

  • DATA command hangs

    - by Tharban
    Hello, what can i do, if a Mailserver accepts a connection but does not return any data? The default javax.mail implementation just hangs indefinitley. Event setting the smtp.timeout does not help - it still hangs. I even tried to set a custom SocketFactory to set the sotimeouts and solinger directly, but it still hangs. Somehow the socket does get kept alive? But how? Thx for any ideas! Ciao, Nils

  • HTML Canvas and saving the data on the server

    - by snitko
    Say I've written a simple app that draws circles in browser. Now I'd like to let people save their pictures. How would I store the data on the server? Which format would be the best option? Should I simply store the relevant html? What would be the case when I would want to make a custom format that is stored on the server and parsed back to html canvas when loaded?

  • Default Sorting in DynamicData

    - by Jens A.
    I am using DynamicData in the version that shipped with VS2008. In the default List view, the data is sorted by order of entry into the database. I'd like to get it sorted by a field of a specific name (descending). As a last resort I tried to use the OrderByParameter of the LinqDataSource with a QueryStringParameter, but I could not get it to sort anything. =) Is there an easy way to accomplish this?

  • modal forms and shared data,

    - by Tumble
    I've written a couple of c# forms applications which use a lot of the same data/objects which would better be combined. I realise I could use modal forms to launch each of these but where should I state .dll's and other resources, on the parent form? or on each other form where necessary?

  • How to version control data stored in mysql

    - by Shawn
    I'm trying to use a simple mysql database but tweak it so that every field is backed up up to an indefinite number of versions. The best way I can illustrate this is by replacing each and every field of every table with a stack of all the values this field has ever had (each of these values should be timestamped). I guess it's kind of like having customized version control for all my data.. Any ideas on how to do this?

  • Create DB in Sql Server based on Visio Data Model

    - by Yaakov Ellis
    I have created a database model in Visio Professional (2003). I know that the Enterprise version has the ability to create a DB in Sql Server based on the data in Visio. I do not have the option to install Enterprise. Aside from going through the entire thing one table and relationship at a time and creating the whole database from scratch, by hand, can anyone recommend any tool/utility/method for converting the visio database model into a Sql Script that can be used to create a new DB in Sql Server?

  • Manipulate data in the DB query or in the code

    - by DrDro
    How do you decide on which side you perform your data manipulation when you can either do it in the code or in the query ? When you need to display a date in a specific format for example. Do you retrieve the desired format directly in the sql query or you retrieve the date then format it through the code ? What helps you to decide : performance, best practice, preference in SQL vs the code language, complexity of the task... ?
