System Design Question
Jan 29, 2008
Hi,
We have a relational DB that holds information on West Nile Virus. Currently, we have 5 tablet PCs that take a full copy of the DB and updates/edits are done in the field.
Once a month, the tablets come back and someone manually takes the 5 databases and uploads the changes to the central database. I want to find an easier way to do this. Some sort of 'synchronization' type of process.
Can anybody recommend anything? I am not too experienced with Access and this sort of functionality.
I think ideally I would create an application to check data in and out of the central DB, but I'm not really sure where to start.
Any help is appreciated.
Thanks!

I am designing a shipping container tracking system for my work and would like to know what the best design is for this.
There are many excel sheets that provide data on the status of containers along the supply chain i.e. shipping schedule, data from the logistics supplier showing status at the wharf, data for movements on our site etc.
Each container has a unique identifier according to what stock it carries and also a container no. designated by the shipping line. I was planning on use the first one as a primary key.
My first instinct was to have a main table that contained all of the information, with queries that updated the fields from the other data sheets.

I have our primary web based inventory system that I am exporting to Excel and using this as an import to Access for the main raw data for my database. This being inventory it changes daily so I am updating this table every day. When I try to append the table it ads all the records. I am wanting an easy way to add only the new records/take out the ones that are no longer there. Basically update the table with what is currently there.The only have I have found to do this is by running non-matching queries and update queries.

I have had to use my first crosstab queries.
I now understand that when opening and saving crosstab queries Access (2010) runs that query to ascertain the column names. Unless you hard-code them. Running the query takes at least 20 minutes.
I have hard-coded where I can, but one report takes arbitrary dates so I can't hard-code them.
I believe that turning off AutoCorrect might make a difference to whether the query runs - but I don't want to turn it off.

I have a sub form in DataSheet view and I would like to lock the design so that the User should not change the layout
Even when I set the property of the Datasheet “Allow Design Changes: Design View Only” users are able to unhide the hidden columns and they can also change the size of the column by dragging the column end line
Does any one know how to lock the design of datasheet ( I am using this sub form datasheet for data entry but do not want users to change the layout)
Thanks

I'm going to make up names and values -- I'm interested in the structure.
Table ALPHA:
COLA DAT1 DAT2 DAT3
1 5 7 9
2 4 14 8
Table BETA:
COLA_IND DAT1 DAT2 DATN
1 a b c
Table CHARLIE:
COLA_IND DAT1 DAT2
2 d e
Table DELTA:
COLA_IND DAT1 DAT2
2 f g
Ok, the idea here is that the data in table ALPHA contains data with COLA a key such that selecting 2 would yield the data row "4, 14, 8."
Now, COLA_IND is a "COLA" key for table ALPHA (sorry, I can never remember which side is called the foreign key). So, from tables BETA, CHARLIE and DELTA, I can access any row in ALPHA based on the key "COLA_IND"
Here's the fun part. When I build my query, it wants to use an inner join on the keys from all these tables... In order words:
SELECT blah blah blah INNER JOIN blah ON (ALPHA.COLA=BETA.COLA_IND) AND (ALPHA.COLA=CHARLIE.COLA_IND) AND (ALPHA.COLA=DELTA.COLA_IND)
What I'm looking to do is expand BETA, CHARLIE and DELTA with the information from ALPHA based on the key COLA_IND. I don't think this is doing what I want.
Any comments?
Thanks in advance...

Hey,
I've got this problem and im 95% sure its going to need a query in order to achieve this answer im looking for.
I'm creating a Software Licensing Management db and its all working lovely. However my only problem remains is the graphical representation (text box within one of the forms) of howmany licenses are/aren't(doesnt matter if this number is a +/- number) available.
In order to achieve this answer I dont think you'l need the table structure of any of my tables other than these two:
tblLicenseInformation
License_ID
LicenseDescription
NumOfLicensesPurch
SoftwareOverview_ID
tblHardwareSoftwareLicense
HSL_ID
Hardware_ID
Vender_ID
Software_ID
AppEdition_ID
AppVersion_ID
SoftwareOverview_ID
License_ID
However I would like to add a column to either of these tables named 'Availability' or something similar which will show the licenses available.
I've tried a number of Update/Append queries but all have failed. I want this Available running variable held within the table due to it not changing to much of the current db design as i baisically finished the project and they asked for it! any ideas of how to efficiently achieve this will be much appreciated!
cheers

I'm looking for a keyboard shortcut to expand the columns in "design view" of a query.
What I mean by this is rather than selecting all of the columns and double clicking to see the entire text, I'd like to be able to a shortcut.
The entire process as I see it involves 3 steps so I will need thesolution to the 3rd step.
(1) [ctrl+spacebar] to select initial column
(2) [shift+arrows] to select all of the columns I need
(3) [keyboard shortcut] will expand all of the columns "field" names to the size of the column heading
Alternatively, if you know of a shortcut that will expand the columns without having to select them first I'll take it!!

I am still a bit confused about the system.mdw file.
I create FE and BE on my local computer and change name of system.mdw to say Jobs.mdw, after backing up system.mdw I then join jobs.mdw with my jobs FE and jobs BE and set secutity settings, etc. I then place
FE, BE and Jobs.mdw all in the same folder.
I now email jobs database with jobs.mdw file to client which places FE, BE and jobs.mdw in Jobs folder on server. Shortcut for fe is placed on each local machine.
My question-Does Jobs FE and Jobs BE still access Jobs.mdw even though placed on another computer and possibly another version of Access?
Does the shortcut have to reference Jobs.mdw?
I need to understand this.
Thanks,
Jim

Hi, I am trying to implement my Database with an enquiry (or quotation) table and I am not sure I am heading in the right direction:
-We use assemblies made of components and the data are held together in the database with a 'Bill of Material' set up.
-A typical assembly is made of 1 or 2 bodies + Fasteners (straps and screws),
-The body price is calculated depending on his weight and an extra costs can be added with extra tooling and machining,
The costumer ask us for a quotation for various number of assemblies and we send back the estimation of the price,
I am really struggling to see if my tables are set right and this is what I came up with (attached rr.zip):
A main Enquiryfile Table is linked to an enquiryDetail Table which would record each individual item information for each Enquiry.
I have also added a Extracost detail table that would record all the Machining and extra pattern making cost for each assembly.
And finally, and that's what I am far to be sure about, a TblChildItemCost where the price of each components would be recorded (for each enquiry detail). The body price is based on his weight but also depend of various market exchange rates, that is the reason why I have created a table for the price of component for each enquiry.
I really hope someone can help me on that one...Thanks in advance.

Hello,
My application I develop should retrieve some meta data from Access system tables. It should find:
- What tables are stored in database.
- What columns have each table in database.
- What relationships are between tables in database.
I opened systems tables of some .mdb file and took interest in such kind of information. But I got some problems by looking for what exactly I need. Please, could someone help me at these points:
1) I found that in system table MSysObjects I can find names and ids of tables created by user (for example by me). But how to determine that these tables are created by user and they are not let’s say a system tables?
2) I didn’t find any meta data about columns of tables! How to determine what columns has each table?
I created application which uses MS SQL Server to retrieve such a kind of meta information and there where no problems. But I stuck using Access.
I was looking for some information in Internet but ineffectively. Please, help me...

I have two tables, one named Loan and one named DVD Details.
On my DVD details table i have a field name, on_loan with a data type yes/no.
I have created a form called LoanForm where i want to select a DVD with a combo box,
then select a Set loan button that will set the corresponding DVD on_loan field to yes(true), in the dvd form.
on the button i have the following code
Private Sub HireDVDButton_Click()
Update dvd
Set car.on_loan = True
End Sub
But it doesn't seem to set the on_loan field in the DVD table to true, which is what i want to do.
Sorry if it's not clear what i want to do. I am just a beginner.
Thanks in advance :)

Hi there,
I'm working on my A2 IT Access project atm, and my aim is to produce a fully functional db for use by a golf course, incorporating membership information and tee-time reservation system.
I've got the membership side pretty much sorted, so now I need to start work on the reservation system.
But where to start?
Basically, the user needs to be able to view slot availablity on a specific day, and make/change/delete bookings quickly and easily. The booking also needs to contain the party size. The bookings themselves should relate back to the specific member that made it via the MemberID field.
The user should be able to make bookings upto 6months in the future.
Block bookings should also be possible, so that the admin can block an entire day out for a tournament therefore preventing member bookings.
The first available and last available slots also need to be editable by the system admin to take into account time of year, light conditions etc.
Right, so i know there's quite a lot there, and i'm sure i'll come up with more features that would make it better.
But as it stands, that's something to get me started.
I'm not asking for someone to do the project, just to point me in the right direction as to suitable table structure, how to "make" the slots, how to store the bookings in the table, etc.
So, any input and ideas are greatly appreicated.
Cheers
Gavin W

I just found something interesting.
I have a small db open. One form, viewing info.
I notice in Windows Task Manager that MSACCESS.EXE is taking up between 70 to 97% sometimes 100% of systems resources.
How could this be?
Cheers!

Is it possible to loop through all forms within a project and look at its controls? I was requested to change some object names to a more generic name, but I would like to find all references of the form within the Access application. Is there an easy way to do this?
I know that the MSysObjects contains the listing of all forms, but I don't know how to generically type cast a local variable to the form name listed in the table.
Does this make sense? There has to be a way to do this, but I haven't found anything in searching this forum.
Thanks in advance.

I have little experience using Microsoft Access, but am attempting to create an order management system.
I have designed a system to store customer details and allow the entry of orders. I now want to develop this so that the system can handle delivery notes.
There are currently two tables for order information, since each order can consist of multiple items. So, general information, like the order date, order number and salesperson are stored in an orders table. A second table, Order Detail lists the items and item specific information along with the order number of which they are a part.
A whole order (i.e. all items assigned to one order number) may be delivered at once, or in smaller consignments. However, every consignment must have a delivery note with a unique number. So, there may be several delivery note numbers associated with each order, relating to different shipments.
I therefore need to create a system which allows the user to select which items from an order are being dispatched and then get Access to do the following:
Create a new record in the delivery notes table. The delivery note number will therefore be created (it's an autonumber). The user should be prompted to enter the delivery date and this should be stored in the date column of the delivery notes table, alongside the delivery note number.
Enter the delivery note number in the "Delivery Note Number" field of the Order Details table, for every item that the user selected as dispatching.
Once this is in place, I will then be able to pull all the required details together with a query and then print the delivery note.
Bearing in mind that I'm very new to Access and so don't have any knowledge of scripts/macros etc, can anyone tell me how I can achieve this?
Many thanks in advance,
Gary
