  • Grabbing "last saved by" metadata from access '03 file to excel '03 in VBA

    - by Spacious
    So I am in Excel trying to read the last saved metadata from an Access database, but I cannot figure out how on earth to do this. If I use environ$("username") it will give my the last saved information for the excel document where I am coding, not the access db that I want it to grab from. Excel has a built in function for grabbing username data, but I cannot find one for access. How can I do this?! Any help is greatly appreciated!

  • How to build a tree from a list of items and their children recursively in php?

    - by k1lljoy
    I have a list of items stored in the DB, simplified schema is like this: id, parent, name I need to generate a tree structure (in a form of a multi-dimensional array) that can be infinite levels deep. Top level items would have parent = 0. Next level down would have parent equal to the the id of the parent item, fairly straight forward. What would be the best way to do this, while consuming as little resources as possible?

  • Muliple Models in a single django ModelForm?

    - by BigJason
    Is it possible to have multiple models included in a single ModelForm in django? I am trying to create a profile edit form. So I need to include some fields from the User model and the UserProfile model. Currently I am using 2 forms like this class UserEditForm(ModelForm): class Meta: model = User fields = ("first_name", "last_name") class UserProfileForm(ModelForm): class Meta: model = UserProfile fields = ("middle_name", "home_phone", "work_phone", "cell_phone") Is there a way to consolidate these into one form or do I just need to create a form and handle the db loading and saving myself?

  • Is it possible to use SQL XML to insert, and get output from each record?

    - by nbolton
    I would like to perform a SQL XML insert (on MSSQL), and in this case I need to insert a list of files into the DB (this is simple enough). However, there's an auto generated PK column (ID), and I need the ID for each newly created filename without performing a 2nd query. Is this possible? I guess it doesn't matter if the result is/isn't XML, but the input certainly has to be.

  • Passing around a SqlConnection

    - by Chris
    I have created a TransactionScope and within the scope various items are created and updated in the database. During this process I make a lot of calls to the database. Originally I opened a SqlConnection in the beginning of the TransactionScope and passed it around to any function that made a DB call then I closed the connection after all the calls are made and before the transaction commits. Is it better to do this or to open and close a connection for each call?

  • Programmatically creating linked tables in access

    - by newtoaccess
    Hi all, We need to find a way to programatically *link all the tables* in a SQL Server database to an access db. We will be invoking this access database from a program that uses .net/SQL Server 2008. While invoking the application we would like to add the linked tables so that the users can just run the reports/modules from access without having to worry about linking the tables. Is there a way we can do this? Thanks!

  • I have a feeling that adding fields marked with @Transient annotation to entity is very bug-prone. A

    - by Roman
    I have some philosophical feeling that adding to an entity fields which doesn't mapped to the DB is a wrong way of solving problems. But are there any concrete situations where using @Transient fields leads to implicit and hard fixing problems? For example, is it possible that adding/removing 2nd level cache will break our app when there are @Transient fields in our entities?

  • Can I write a test without any assert in it ?

    - by stratwine
    Hi, I'd like to know if it is "ok" to write a test without any "assert" in it. So the test would fail only when an exception / error has occured. Eg: like a test which has a simple select query, to ensure that the database configuration is right. So when I change some db-configuration, I re-run this test and check if the configuration is right. ? Thanks!

  • How should I ethically approach user password storage for later plaintext retrieval?

    - by Shane
    As I continue to build more and more websites and web applications I am often asked to store user's passwords in a way that they can be retrieved if/when the user has an issue (either to email a forgotten password link, walk them through over the phone, etc.) When I can I fight bitterly against this practice and I do a lot of ‘extra’ programming to make password resets and administrative assistance possible without storing their actual password. When I can’t fight it (or can’t win) then I always encode the password in some way so that it at least isn’t stored as plaintext in the database—though I am aware that if my DB gets hacked that it won’t take much for the culprit to crack the passwords as well—so that makes me uncomfortable. In a perfect world folks would update passwords frequently and not duplicate them across many different sites—unfortunately I know MANY people that have the same work/home/email/bank password, and have even freely given it to me when they need assistance. I don’t want to be the one responsible for their financial demise if my DB security procedures fail for some reason. Morally and ethically I feel responsible for protecting what can be, for some users, their livelihood even if they are treating it with much less respect. I am certain that there are many avenues to approach and arguments to be made for salting hashes and different encoding options, but is there a single ‘best practice’ when you have to store them? In almost all cases I am using PHP and MySQL if that makes any difference in the way I should handle the specifics. Additional Information for Bounty I want to clarify that I know this is not something you want to have to do and that in most cases refusal to do so is best. I am, however, not looking for a lecture on the merits of taking this approach I am looking for the best steps to take if you do take this approach. In a note below I made the point that websites geared largely toward the elderly, mentally challenged, or very young can become confusing for people when they are asked to perform a secure password recovery routine. Though we may find it simple and mundane in those cases some users need the extra assistance of either having a service tech help them into the system or having it emailed/displayed directly to them. In such systems the attrition rate from these demographics could hobble the application if users were not given this level of access assistance, so please answer with such a setup in mind. Thanks to Everyone This has been a fun questions with lots of debate and I have enjoyed it. In the end I selected an answer that both retains password security (I will not have to keep plain text or recoverable passwords), but also makes it possible for the user base I specified to log into a system without the major drawbacks I have found from normal password recovery. As always there were about 5 answers that I would like to have marked correct for different reasons, but I had to choose the best one--all the rest got a +1. Thanks everyone!

  • Do something before closing the browser window

    - by Adam Kiss
    Hello, we have an web-application built in flash (it's actually just getting built :D) where is very important to be notified, when user closes his window. Since it's in flash, we do not worry about Javascript, we do not support non-javascript users. What is the safest (meaning it's 100% sure it gets called) X-browser way to call php script to close session, make some db changes, etc.? Thank you
