Protecting The Database - What Kind Of Solution?
Oct 11, 2005
Hi there,
I have built a Access solution for a music school, It was installed on 3 machines.
I'd like to protect my database from installing onto another machine without my permission.
I did install database as a mde file so they cannot see my codes. However, if they copy the database to another machine (esp. another machine in different school) they can use my software without my permission. How can I prevent this? If they copy the mde file into unauthorized machine, database should work as a demo version (such as limiting the number of records in tables to 10). How can I do this? What should I check, hd id, mainboard serial or what? Is there any ready solution (at least modifiable) for that kind of problem?
regards

(see sig for details on what I'm capable of before you toss code at me ;P )
Here's my current setup:
Table1(Assignments)
Instructor <related to Instructor table, pulls data from there)
Academic Year
Fallcourse# (where # = 1, 2, 3, 4), (course pulled from Courses table)
Fallcourse#comp
Fallcourse#notes
Wintercourse#
Wintercourse#comp
Wintercourse#notes
Springcourse#
Springcourse#comp
Springcourse#notes
Table2(Courses)
Coursename (unique)
Coursetype (required, elective)
Courselevel (ugrad, grad, MAS)
Table3(Instructors)
lastname
firstname
empID
rank
The purpose of the database is to assign courses to various professors and append supplementary compensation and, if necessary, notes to each course assignment. Each professor can be assigned up to 4 courses (or something to take the place of a course) per quarter.
My problem. I have created a quite a few reports with this setup including an academic year schedule, compensation reports for the year, sabatical / course release listings, etc. I am having trouble with what I am hoping to be my final report.
Requirements for the final report:
List of all courses for an academic year (filter by year)
group by level (easy)
group by type (easy)
append instructor's name to the end
Report/Relationship Problem:
I can't seem to set the relationship to allow more than one field's data into the report. I can only show courses from the [Fallcourse1] because I can't relate multiple fields from the "Assisgnments" table to one field in the "Courses" table. Effectively, that's what I want to do, but my mind's burnt and can't seem to figure it out.
Maybe you guys could help me out? Suggestions, questions - all welcomed.

Hi,
I have a database that has been created for a company - all of the queries they need to run and changes they need to make to DB data is done through a series of Forms. Is there a way I can make it so all they can do is access the Forms (so they can't right-click and edit the form or edit any code etc.)
Thanks!

Hello,
I designed and distributed a database client to a bunch of users. They have asked me to password-protect it so that anyone can open the database and view the forms, but a password is needed to actually make any updates. I am trying to do this, but everything in Tools--Security is making my head spin. I have actually already managed to somehow lock myself out of my own database, although I have another copy.
How do I set the Workgroup Administrator Files so that they apply to anyone? It wants to put a separate file on my C: drive, but I don't use this database, I distribute it to people who do. (The server is on a share drive, can I put the Workgroup file(s) there?)
What settings do I modify to require *anyone* to need a password to update? Or is that even possible? I don't really want to break up the users into different categories.
If anyone could walk me through this process I would really, really appreciate it.

So i want to protect the back end of a database but im limited to what I can do....I am unable to restrict members from accessing the file by username...I am unable to place it in a local area which is pass protected...I am also unable to encrypt the back end as the front end needs to be able to access it (and I dont know how to allow it to do that...)

Hi,
Im very new to sql so please excuse my ignorance, I ve been trying to do this for a while and not getting anywhere:
I have a table that has customer and product data in it. Its super market data.
I have a field that has customer education level (education), this holds text, (bachelors degree, graduate degree, high school degree, partial college, partial high school)
and a field low_fat which is boolean (0 or -1), wether the product purchased was low fat or not.
Im interested in the realtionship between education level and number of low_fat products purchased.
I'd like a resultset that counts the number of low_fat products purchased for each category of degree level. Something that looks like this
EDUCATION Low_fat_Count
bachelors degree 500
graduate degree 234
high school degree 124
partial college 333
partial high school 124
Is this possible?
So far I've come up with this:
SELECT education, COUNT(*)
FROM AllTablesMerged
WHERE low_fat=-1
GROUP BY education;
but access asks me for specify parameters for education and low_fat.
Thanks in advance for any help on this!

Can anyone give me a direction for the following problem please :
I would like to create a yearcalendar that might do the following job for me:
I have 12 firms with different amounts of people working for them. We need to see those people once a year and give every firm an amount of days that they can come see us.

Hello all,
I need help with making a query this will check the OrdQty for all items in a specific order against the Sup1inv field, then if supplier 1 can not fill the order have it check against Sup2inv field.
Here is an example of the data im working with
Order# Item# OrdQty Sup1Inv Sup2inv
555 widget1 2 1 3
555 widget2 1 1 4
556 widget3 1 3 0
557 widget1 7 1 3
The part i am having trouble with is making sure the query "understands" that both items on order 555 are the same order so the end result would tell me that order 555 needs to be placed at supplier 2, not 1.
Thanks in advance for the help,
Eddie

There are total three tables tblInternal, tblExternal, tblCourses. Table
tblInternal and tblCourses is one to many relationship by reference foreign
key InternalID from tblCourses to tblInternal. If I just use these two table
to set up Master form and subform in ACCESS, you can in subform Field Linker
window of subform property Data tab select primary and foreign key to
generate link between Master and subform. So if you select user name from
tblInternal in Master form ComboBox, you can see the detailed information the
user relates to.
Same relation between tblExternal and tblCourses.
Now I want to merger tblInternal, tblExternal to list user name in ComboBox
by Union statement. But in SubForm Field Linked window I just see one primary
key from one of these two tables instead of two primary keys from each table.
How to solve this issue?

hey,
Sorry to open with a question but its usually the way, i'm quite an experienced computer user but never used any office products before and just thought i should learn as i'm losing money every week by not keep track of things properly.
So then to my question..
I've made a table to cover all the orders i have had placed, this includes a date column for when that order was placed. I just wondered if it would be possible to have some kind of system where after 7 days without any acknowledgement from me it either pops up or turns red or something similiar. I'm thinking the acknowledgement could be the yes/no box and i tick that when i recieve the item back, if i dont it either pops up or turns red or something :confused:
any help much appreciated

Hi,I'm looking for a bug/issue tracking solution done entirely in MS Access. Does such a thing exist?My requirements are that it must need only Access, and be accessible in a shared environment solely by opening a .mdb file from a shared folder. It must support various issue lifecycle related things, and the stuff those tracking systems do in general.It may or may not be commercial software.If anyone knows of such an available solution, please let me know.(And yes, I've searched on Google, and haven't found anything worthwile, so that's why I'm asking here now.)thx

Hi,
I haven't worked with Access for a while, now i'm working on a project and just can't handel with a calculation. I have somewhere the solution for my problem, I had use it other times, but now i just don't know where to find that sample database.
I have 2 tables: tblProjects and tblCosts
tblProjects
ProjectID
ProjectName
ProjectValue
...............
tblCosts
ProjectID
CostName
CostValue
................
What I want is to calculate the Benefit=ProjectValue-CostValue.
I know it is possible, in other cases I have used some union queries, sum calculation and I had my results very simply. But now, as I said before, can't find that piece of SQL. :(
Any solution is appreciated.
Thank you

I need to try and create a simple form that a user enters data into and then hits a print button and the text they entered is printed in a particular way.
i.e. they type in someones name, job and company into 3 fields and then hit a print button and this then prints :
PERSONS NAME
JOB TITLE
COMPANY
We also need the print to be formatted a particular way but that is another issue
This is for a small exhibition we are trying to run and we need something to print visitor badges with

Hi the specialists.
I do not want security on any of the files in my computer.
I'm placing this in "general" because I'd like a direct and practical answer, please. And if there is none, please say so. Computers are immensely complicated and I am just a little bit tired of people superciliously refering the uninitiated to "Microsoft's FAQ's" That source is to most normal humans as obscure as the software programming itself.
I have also searched this source and Google for hours, without getting an intelligible answer.
This is my problem:
I am the only user and administrator on my computer.
I have a back-end file which is easily accessed through the front-end.
.... but
I cannot open the back-end to access the tables directly.
I get the following error message:
You do not have the necessary permissions to use the 'C:Documents and SettingsAll UsersDocumentsAccessThingsWORKLOG_be.mdb' object. Have your system administrator or the person who created this object establish the appropriate permissions for you.
Of course the person who created this back-end is me, but I have no clue what I did, because it is at least two years since I created it.
Could someone please help?
I have tried to use the "shift", click method. It does nothing - just gives me the same message.
Pierre.

Link to the original thread (http://www.access-programmers.co.uk/forums/showthread.php?t=89557)
I have realized what I was doing wrong and thought that I would post the solution in case anyone else does the same trying to implement security. First off thanks Pat Hartman for the input. You were right on there needing to be a cutoff and now one is added that ensures they can't edit punches after payroll has started.
I had the right idea with the many to many relationship to get a list of buildings. What I was doing wrong was joining the resulting table to the shifts table. Instead the correct way (well, it works anyways) is include WHERE Building IN (SELECT ....) in the sql where the select statement gets the list of buildings numbers that I have access to.
Now the list is limited to the buildings that they have access to and when you delete only the shift table is affected because none of the other tables are joined.

Hi Everybody. I've been nosing around here because I have this difficult problem with a database design. I modelled my program in UML so I have a class diagram. Now I want to create an access database out of it, but this is too hard for me.
It's about a school project for flowers. Every year, they make a cross plan. This cross plan contains crossings. Many crossings. And every crossing exist from 2 genotypes. A mother and a father. With this crossing several new genotypes are created. How on earth do I realize that in a database? A plant is male as well as female so you don't need to indicate which sex it is.
Further more I want a genotype to be judged on his characteristics by a user as much as he wants to.
Well...I hope someone can help and if you have questions about it don't hesitate to ask.
Thanks in advance!
Gr Billy

Good afternoon all,
I have a A97 Db. On one of my forms (see attached screen pic) I have a field "Payment type" for either Cheque, card of Account. There is no code or functions behind it, it just stores a value.
Trouble is my users keep forgetting to fill it in!
My first (and easiest) solution would be to make "Payment type" a required field. However. The field will only be filled out under certian conditions.
That is if the "Status" field value = "X" (drop down box holding two values "X" and "Y").
What would the code be? I presume it would be in the Form "after update" field? Would read somthing like:
if [Status] = "X"
and
if [PaymentType] = "Null"
then
mssg box "Please enter payment type"
I have a vba book on order to start learning, but as you have probably guessed, I have not received it yet! :)
Any pointers or info would be much appriciated. Many thanks :)

I need a little bit of advice on this one.
I have 2 tables that are used for different things, one table, denial data, is used for tracking all requests. It is updated with the form, Daily PAs. On the form are 2 buttons, each running a macro. One button exports the data to Excel by running a query to specify the date range. The second button is my problem. It also has a macro, with an append query, to append only requests that have been denied to my second table, Denials, to be later updated with additional information. The append isn't working because I am getting three different errors, a "type conversion failure," "key violations", "lock violations" and "validation rule violations." Now, I know I can begin working out these violations and get it working, but I'm sure that involves a lot of time and coding. I would really appreciate any other suggestions to accoplish the same tasks. I need to keep the approved requests seperate from the denied requests for auditing purposes. Thank you for your help.

Hello All
I am in need of a lot of help. The situation is as follows I have a table with users that have certain classes that they have to take and in another table I have the dates that these classes are offered. My problem is I want to find a way to map all the students to their required class by scheudling them into the required classes taking into account date conflicts and classes required before taking a certain other classes. I guess my question is if there is any possible to do this in access without me phyically having to schedule each users required classes to the correct time making sure there are no date conflicts. Any help would be highly appreciated because we are talking about 3000 users that need to have schedules and that is extremly time consuming if I have to sit here and do the schedule for each user. Thank you in advance for your time

I want to use a counter increment so that I can loop F1 to F3 I don't want to create 3 (actually I'm trying to avoid creating 50) If/EndIf blocks of code. Can someone help me?
' Initialized memvars
F1 = "PO_Num"
V1 = "0001"
F2 = "Vendor_Num"
V2 = "0002"
F3 = "PO_Num"
V3 = "0001"
TableName = "MyTable"
QueryStr = "UPDATE " & Tablename & " SET "
mCtr = 1
Do While mCtr <= 3
If Not IsNull( Eval("F" & Trim(Str(mCtr)) ) Then
QueryStr = QueryStr & Eval(FValue & " = '" & Eval(VValue) & "';"
End If
mCtr = mCtr + 1
Loop
The way that it works:
Do While mCtr <= 3
If Not IsNull(F1) Then
QueryStr = QueryStr & F1 & " = '" & V1 & "';"
End If
If Not IsNull(F2) Then
QueryStr = QueryStr & F2 & " = '" & V2 & "';"
End If
If Not IsNull(F3) Then
QueryStr = QueryStr & F3 & " = '" & V3 & "';"
End If
mCtr = mCtr + 1

I need help on an update query. Case is an automatic letter generation for particular document which has revisions like 00 or 01. So when this is done, on click, open an update query to update date and letter no in main table against that particular document. I made the query but does not work and says result should be an updatable query. I am posting SQL below.
UPDATE [MDL-10], TRANSMITTALGEN, [Transmittal Record Query] SET [MDL-10].[REV 00 SUBMISSION] = [Transmittal Record Query]![MaxOfTransmittal Date], [MDL-10].[REV 00 SUBMN LETTER] = [Transmittal Record Query]![MaxOfTransmittalNo]
WHERE (((TRANSMITTALGEN.REV)="00") AND (([MDL-10].[Select])=[Forms]![TransmittalGeneration]![Text2]));

I have almost finished my current database but I was asked to create a log table/log file that would list changes made to every record. Now my current database don't allow duplicate records, so any advice pointing me into the right direction will be helpful. I have ran through the search area and found nothing that I can use. Can any one help me out in this specific problem. I picked up a few books and none of them give examples of such things. Thanking you all in advance...
