Time Limits On Accessability
Oct 15, 2005
I want to distribute an app that provides password access for a 6 month period after which time a new password has to be issued by me to the end user for them to continue. This means that I don't lose control of the programme.
Is this possible or are then other ideas to protect the app - I have looked at upsizing to MySQL but it is way beyond me, also I have looked at splitting the app and putting the back end on FTP - but apparently this doesn't work (albeit a good idea as I don't need any other programming skills). Any solution needs to be fairly simple please.

I need to implement some type of security on my database to limit the forms/reports users can access. When implemented it will be a split database on a network. I'd like to set it up so only certain users can edit/add data on certain forms. Also I want to have more than one user be able to edit/add data at the same time. I'm confused as what I need to do to set up this type of security. I found another post on this forum by Oldsoftboss (Dave) that gave a good, working example of a database with user login screens and different user security levels. My questions are:
1. Can I use his system in place of the built-in Access security?
2 . Do I need to implement both? If I don't use or change the access rights in
Access security, won't everybody be logging in with "Admin" rights?
3. What do I need to do to let multiple users work in the database at the same
time? I've already changed the database to "shared".
4. I don't want the users being able to change the forms, queries or reports
so I'm distributing an MDE file. Is there anything else I need to do so
users can't access the "design" button?
Needless to say, this whole security thing confuses me. Any help would be appreciated.

Hate to throw this issue back in the mix, but I seem to be really struggling to find a solution, even after extensive searching through posts. I can't seem to pin down any existing posts that directly addresses my problem, so here it is:
I have a DB that needs to be accessed by no fewer than 9 users for data entry and retrieval, no designing or programming. I seem to be running into a multiple user problem revolving around exclusive opening of some sort.
As it stands, about 4 users can open the DB simultaneously without issues. But as soon as a 5th person tries to open, they get an error saying they do not have exclusive rights, and the other 4 members run into problems closing their opened forms or tables with a "cannot save due to another user already has it open" and an error loop. Then, no one can close because of the auto save function in access.
I believe this may have something to do with workgroups, and have searched the forum with this keyword, but I'm not sure if this is where I need to go. I also don't know how to set it up from start to finish. Do I need to do something on each user's individual computer to make it work? And once I have one set up, will this absolve my current multi-user issues by specifying a shared access at all times?
Please help, as I'm getting a bit tangled up in the steps of this process. Is there a different solution? Thanks for any advice you can offer.

Ihave placed a code on the OnEnter event of the subform as such,

Hey buddays,
I have a form with a bunch of Count totals in the footer.
There are 12 different areas with a number of projects in each area. So, I'm counting the total projects, and then I'm counting the instances of an area in the area column...12 times. In the query, I have 12 different Count fields, and in the footer of the form, I have Sum([Count]) for each area and one normal Count field for Total Projects. It works fine, until I have about 11 or more text boxes summing counts. Then I get #Error for all of them.
What's the magic Access limit for form-based functions like this? What's a better/faster/sleeker way of doing this?

Hey guys, I asked a question before but not sure it's the right place and was difficult to explain anyway so I'll just upload my stuff here.
Basically its a school assignment that's making me so frustrated. progress was fast with tables and forms and reports but there are a few requirements i just dont KNOW how to do, not sure what to search for it the way of google either so it's making life hard.
so requirements are:
Gold memebers can book a max 7 classes, silver 4 and bronze 2.
Members cannot book 2 classes on the same day
Classes cannot be over booked.
must make in some form or other something that displays how many classes taken and how many classes are left to each member.
I know all this stuff probably falls under some very simple functions that I'm just not using correctly or have no idea exist but I've made no progess in days and it's such a horrible feeling!
Please any help! I'm not asking you to complete my assignment I'm just asking you to shine the light my way!
ps, no code please, we havent got to that stage yet.
thanx in advance,
Joe

I have two queries combined into one query. The first query shows a sales summary by part number. No problem so far. The second query shows inventory by part number. No problem with that.
Now, I combine the queries, and get only those results that appear in BOTH queries. In other words, if there is no inventory, I do not get zero in the inventory column, the entire result for that part number is skipped.
How do I still display the results of the first query if there is no match in the second query?

Hey guys,
Was wondering, what is the recommended maximum size for Access databases? I've heard that for very large databases that oracle is preferred. Would Access be appropriate for something on the scope of 5000 records of roughly 6 text and 2 number fields? Do people ever notice performance effects on databases of that size?
Also are there any ways to help reduce the size of the database? Do you recommend change the default field sizes where appropriate and would this have a noticeable effect on a database of this size? Any other suggestions to help keep the database manageable, and functioning?
I'm basically trying to figure out if there's much to worry about here, before I start importing my data. Thanks.

I am trying to project how long it will take to reach the 2GB Access limit in a specific project.
My client downloads approx 250,000 records on a monthly basis. I've been provided w/ a sample Excel spreadsheet. I filled a spreadsheet w/ the max number of rows (65536 rows w/ 10 columns of data), and imported that into a new table in a new .mdb file. I copied the table 4 times, so I now have 4 tables of 65536 records each. Compacted before closing. Size was about 52MB. Assuming consistency, I calculate that the size limit would be reached in about 36 months.
262,000 records = 52 MB. 52 MB a month x 36 months = 1,872,000 MB.
Does my projection appear sound?
Thanks!

I am a very new access 2003 user and would welcome advice on how to cause the parameter text within [xxxxx...etc]to occupy two lines ( i.e force a carriage return and line feed) and thereby reduce the width of the parameter input box that the user sees. Also are there limits to the number of characters that can be used. I seem to remember a figure of 50 but cannot find it again in any of the books I have.
Many Thanks
Gerry

Why is my query limiting itself to only 16 columns? when I tab right for another field, it jumps back to the first field. I have other queries with far more columns than that. My DB size is 3,400 kb.

I have a textbox called Odours, there are four buttons below the textbox btn_Cadaver, btn_Drugs, btn_Explosives and btn_Money.
On licking one of the buttons a value will be put in he textbox i.e. pressing the btn_Cadaver will put the value "Cadaver ()" in the textbox.
The reason I want this is that all of the entries must begin with either Cadaver, Drugs, Explosives or Money. The brackets are there to allow the user to put some free text between the brackets.
I have some code to set the cursor (on click) between the brackets
Code:
Me.Breed.SelStart = 9
I want to prevent the user from typing anywhere in the textbox except between the brackets.

I will try and keep this brief. I have a paragraph of text, I have to paste it into a system which allows me 75 characters in a line and 208 in a page.
I have code which creates text boxes dynamically based on the total amount of characters/208 - this gives me how many textboxes need creating. I also have code which then populates those textboxes 208 characters at a time. I now need to alter it so it puts a line break every 75 characters.
Code:
Private Sub btnsubmit_Click()
DoCmd.OpenForm "NoteForm", acDesign
Dim x As Integer
Dim ctrl As Control
Dim y As Integer
[Code] ....
So I've achieved almost what I want, I just need to amend it so it starts a new line after every 75 characters...

The BIG problem is this.
I need a basic string graph over time recieved from a cross tab query. The data points all come in fine, but the "strings" / lines connecting the points do not show up.
I believe the reason is because there are just too many records.
I culled the data down using a vba loop to only show 1 stop per minute. (BTW, is there a way to do this using only SQL?) I now show all record points, but still do not show the lines between points. Some of the lines show up, but the more data points on the graph there are, the less the lines show up, till only one or two show.
This is an Access limitation that I'm unsure of how to get around. This really shouldn't be an issue though, because Excel handles the graph just fine EVEN BEFORE the culling of the data down to access acceptable limits. And it shows the lines between each record as well.
Does anyone know of a resolution for this?

Hi
I'm new to forum and can't find an answer to this problem. I am using Access 2002 and have a memo field in a form that I want people to be able to type in as much text as they want. This is then displayed in a report. The form accepts the text with no problems however when I view it in the report it has been cut to 255 characters as if it is a text box. I have set the properties to 'can grow' to no avail. I have searched the MS Knowledge base for a solution with no luck. I admit I'm not an expert in Access and would really appreciate some help as I have been trying to overcome this problem for days.

I have a form with an unbound textbox. I want to be able to enter a sequence of digits and spaces (e.g., 02 950 4187); however, when I paste this into the box, I always have to delete the two spaces until the number is 9 digits long. Then it will accept the number and go look for the prize. How do I get the textbox to accept the number I paste in?

I have an application with a backend db on PC 1, and the same application on PC 2 linked to the backend db on PC 1 via the network.
The link works fine but the time formats are different.
On PC 1 the time format is shortime and displays as it should i.e. in 24 hour clock format
However on PC 2, opening the same database via the network, the time format is still shorttime but when you read the time within the code it comes out in AM/PM format. Also, when the defaul tiem should be #20:00:00# but this changes to #8:00:00 PM#
Weirdly though, when you just open the table, the times are in the correct shorttime format.
Guessing, it must be a setting within the main core of Access 2003 that is different between the 2 instances?
Any ideas?
This screen shot may help:

I have a database that stores information for lab testing. Each time a tech does a "step" in the test process he logs it in the table, using an input form. There are different categories, for example preparation, testing, analysis, etc, and each of those steps take time. I have the form autopopulate the date and time with NOW() evertime the form is updated. What i want to do is calculate the time it takes to do each in days. I can easily get how many days it was from now since they logged the test, =NOW()-TestDateTime. What I want to do is get the number of days it took to do each step, ie the number of days between each event. Is there a way to do this?

Formatting issue regarding elapsed time calculated using DateDiff().
I understand that you can specify the output value for DateDiff(). In my case I have chosen "n" for minutes. Each result in my query shows the correct calculation in terms of minutes.
[PunchIn] = 11/23/2013 8:11:28 AM
[PunchOut] = 11/23/2013 5:43:30 PM
[ShiftLength] =DateDiff("n", [PunchIn],[PunchOut]) = 572 minutes.
Now when I try to format the result in terms of H:MM (be it in a form or a report) I get varied results. I'll illustrate an example below:
=Format(([ShiftLength]/60),"0") & "." & Format(([ShiftLength] Mod 60),"00") Returns 10.32 Not correct
=Format(([ShiftLength]60),"0") & "." & Format(([ShiftLength] Mod 60),"00") Returns 9.32 This is correct but I need my result to be in the form of a decimal such as my next example
=([ShiftLength]/60) Returns 9.53333333. Getting there but how do I have this result only show two decimal points 9.53?

I have a date/time text field on a form with the General Date format and a combo box next to it that has sequencial times as the row source (IE. 12:45 AM, 1:00 AM, 1:15 AM, 1:30 AM, ETC.) When the user chooses a time in the combo box, I want the time portion of the text box to be updated with the chosen time in the combo. I have tried a few things but cant seem to get it right.
