Restricting Number Of Open Connections
Jun 10, 2005
I want to restrict the number of times each person can open a database, but give them the option to force close the database on another PC, if they have left it with the database still open, prior to allowing them to have full access / functionality of the database on another PC.
In order to achieve this, I need advice on how to automatically record the computername as each person "logs in" to the database and secondly, send a command to close the database / Access on a PC with the stored computername.
Thanks in anticipation.

Hi,
we use access for localisation in our application. The business object which accessess the access uses DAO connectivity and we often land to
"Too many client tasks" problem.
is it wise to change the DAO to ADO? if so the above problem will go off?
what are the chances that the problem still persists?
is that access has any limits on the number of connections? like 64, 255? or is that ADO/DAO has any limitaions on the number of concurrent connections to access DB?
Pls help, your help will be highly appreciated.
Thanks,
Venkat.

Hello Guy,
We use an Oracle base software called Trapeze and Microsoft Access sometime used as a front end to access the Trapeze oracle tables.
Due to the possible dangers of allowing the users Access, Is there a way to block the users from changing the oracle tables and only be able in MS Access to create reports and queries? Trapeze's security is antiquated and uses Oracle to validate accessibility. Since a user has to be created in Oracle, with update, delete, read, write, append rights, for Trapeze to work correctly, a user can connect directly to the Db through Access and make changes directly to the data, unless the ability to prevent them from modifying the tables and only create reports and queries that they can save.

Hello all, is there a way to change an ODBC connection in MS Access. I have 4 ODBC connections that I can choose from (all of them from the same server), and instead of manually recreating a new ODBC connection everytime, I would like to point it to the new connection. The ODBC connections (Tables) have the same information, but throughout different times during the month.
Thanks in advance for your help.

I have a database that tracks my client information. The forms also include the agent servicing the client and the referral source from where the client came from. I also have tables and forms for each referral source and agent. Currently, if a client is referred by a referral source I go to the referral source table and make a note of it in a text box. Instead, could I tie the referral source and client table together? If, on the client form, I select that a client "Tom" came from my referral source "john" could it tie the client to the referral and note it on the referral form? My referral box on the client form sources the table of my referrals.

I have a query that I want use as a pass-through query (SQL Server databases).
The query has a sub-query that references another database. The query runs fine in Enterprise Manager because EM allows me to access both databases.
If I wanted to I could link both tables through ODBC and then run an Access query that would do the same, however, I would rather use a pass-through-query for this.
The problem is that a pass-through-query in MS Access only allows me ONE ODBC connection (as far as i can tell).
My question is:
Is there a way I can run a sub-query (referencing a different database. i.e. second ODBC connection) which references a second database?
Is this possible?
Thanks

I have split my database and have the front end on numerous PC's. Is this the preferred method of a multi user database? The reason I ask is not all the data is making to the backend - only some records.

Hi!
I'll cut right down to it: I have an ODBC connection to a (SQL Server) test database on my development machine that is identical to the live database to which a (different) ODBC connection exists on the PC where this Access application is to be deployed. The problem is that when I deploy, there are some tables that have to be updates, because they still point to my test database. The other tables look like they use the default database for that user.
I used to be able to just copy the Access application and it would work without having to update any linked tables.
To clarify, the tables that work without a problem look like this in the Linked Table Manager:
t_mytable (DSN=odbc;)
And the problem tables have this:
t_mytable2 (DSN=odbc;DATABASE=my_test_db)
I don't seem to be able to clear that DATABASE= thing up. Can anybody tell me how this works?
If this question is overly trivial, I apologize.

server administrators have expressed concern about my website that it is having a negative impact on the server.
He said this typically occurs when a website has a memory leak (where it obtains server resources and doesn't release them) or is opening database connections and not closing them until the point where no more are available.
I'm using asp.net to control Access and open the connections.
I don't know why it isn't closing them? the website is:
pedalcar.com
Any thoughts of what the problem is and what the statement I need to close the connections?

I have split my database in Front End och Back End, and both are password protected. The Front End has been converted to ACCDE.
When I try to import to Excel from Front End and/or Back End using database connections I receive a message telling me that I am using an invalid password (even though I use the same password when I encrypt/decrypt FE and BE). I've tried using Access import, ODBC and Microsoft Query. (In some cases I 'm also prompted to set a username, which I do not know which it should be since I haven't set one in my database (except the automatic "admin"))
How do I go about to make this work?

Hi
I have made up an Access database form for our Sickness Administrators to fill in when someone is off ill. I want the form to only show (on the drop down list of names) the people that that particular SA deals with - for example, Jill would enter sickness records for the Democratic, Legal & Personnel section. I am not sure how to go about this:
a) if I have one table with all of the employees names on it, is there a way of restricting Jill from seeing any names other than the ones that she deals with?
b) if I have separate tables for each section, would that be easier? and if so, do I just make a "switchboard" for them to click on the appropriate list?
Thanks!

I have built a database to be used by several users. One of the tables contains some fields which I don't want some of the users to be able to see.
All users log in to the database with their own username and password.
How can I hide the fields to everyone except a specific group of users?
Thanks,
Gary

Hi, a newbie needed help here.
I just wanted to ask whether it is possible to restrict records/rows in a table that has the same values (same date to be exact).
For example, I have an order form and wanted to restrict to only 20 orders per day (could be of any date; not restricted to the current date only). Therefore, if more than that, a message box will appear and no more record will be allowed to be saved.
Whether is it possible or not please justify.
Thank you in advance.

Hey guys-
New here, and fairly new to Access as well (although I can stumble my way around). I am building a database in which I have to import the data on a daily basis (there won't be much, if any, data entry- just manipulating/Queries of the imported data). One of the fields I am importing is a 'category' type field. There's no way to restrict the data entry aspect of it before I import it into my DB- so I have to work with what I got.
The users type in the categories themselves- many all match the same name/spellings, some do not. So I assume I'm going to have a Category table with all the acceptable categories already entered into it. What I need is some way for the ones that don't fit the acceptable Category names to be flagged- once flagged I need to be prompted for each record if I want to ADD the category to the Category Table, or, if I want to match it to an existing category in the category table. If I choose to match it to an existing category, it will always keep that new category name so that queries and whatnot are consistent.
An Example-
The acceptable Category name might be 'Fruits'.
Upon importing the file- there might be entries that match that exactly, or- some might be entered as-
The Fruits
Fruits II
The Fruity Ones
If these three were to be in the import file- I want to be prompted to change the field entry to 'Fruits' or create a new category name, and associate that with the new name.
How would I go about doing this?
Thanks!

What would the best way to open a series of queries, if you aren't sure how many of those queries there are? I have the following:
Code:
DoCmd.Close acReport, "SCEFReport"
DoCmd.OpenQuery "ClearTBLQuestions", acViewNormal, acEdit
DoCmd.OpenQuery "Q1append", acViewNormal, acEdit
DoCmd.OpenQuery "Q2append", acViewNormal, acEdit
DoCmd.OpenQuery "Q3append", acViewNormal, acEdit
Which continues as is for 10 or 11 queries named in a similar pattern, then prints a report. However, as the number of append queries is not set (they are generated in a different quantity for different purposes, it's complicated), I am not sure how to check how many there are with that style of name.

What I have is a database that I am using for 3 different sites; NE, NCA, & SCA. What I want to do is have the form ONLY show information for the specific site that the Leader is a member of. I have a security table that contains the persons name, & site location. For example: John Smith works at the NE site; so when he goes to open a form to add/modify/delete members from his site I want him to only be able to see date for NE from the table. So in the listbox NCA & SCA would be filtered.
How can I go about doing this? The forms Record Source is set to the Security Table. Please help so I can do this without having to create a seperate form for each different location. :)

I am trying to set up a database to track truck maintenance, repair, and inspection records for a trucking company. Parts are ordered from vendors, and I have forms set up to facilitate the entry of the information regarding those orders. The problematic form is based on a query. In that query (this form and query deals with the purchase details - product, price, extended price), the product ID is gathered from the inventory transaction table, the product name and price are gathered from the product table (I did this so that price would enter automatically).
Of course, when I change the price, it is changed across all related orders, including those that have been saved previously. I know that the problem more than likely stems from having the info pulled from the products table. I'm just at a loss as to any other option to have the price automatically pulled.

I am new to Access and am currently learning it so that I can construct a database of trivia questions.
I have a "Questions" table with question, answer, type, etc. This table is linked to a "Categories" table with a many-to-many relationship using a junction table called "Questions_Categories". The "Categories" table is also linked to a "SubCategories" table with a Categories as the parent and SubCategories as the child. I have attached the database for ease of understanding.
When I enter data into the "Questions" table using datasheet view, I open up a subsheet that shows me the Category and SubCategory fields which have their own lookups.
My problem is the following: I want each category to have its own set of SubCategories. For example, the "Region-Specific" category has "Canada", "London", and "Ontario" as sub categories. However, the movies category should not have any sub categories. The problem is that when I choose Movies in the sub datasheet, the subcategory lookup still shows Canada London and Ontario when I don't want it to show anything. It doesn't make sense to have a Movies category with a London subcategory.

To the point: I have a column which is a combo box (list) consisting of all the departments of company. I don't want 4 of the departments to show up in my query results. In the criteria field I have tried to use the following:
<> "department name", "department name", "department name", "department"
// Note: I've even attempted to place those departments inside parenthesis. And use ; between the names.
Other criteria I have attempted to use without the results needed are:
1.) Not In
Note: some of the department's name consist of a single name; some are two names with a space between the two names. I have entered the names in the same letter case as they were created in the table's combo list.
Suggestions are greatly appreciated.

I have a very simple Access database that contains a form where users enter sheduling information...I wish to limit a group of users to be able to read this information only and not modify or add to it.
The tables are in a back end mdb. The rest is in a front end mdb. And the users actually use the mde file when working with the schedule.
What in your opinion is the least complicated method for providing some users with the ability to add/modify and some with read only.
Thank you.
Suzanne
