Controlling The Real World With Access?
Feb 6, 2006
Hi there,
Is it possible to control a lighting system from Access using a combination of VBA code or Active X add ons with some specialist hardware and cabling attached to the PC, etc ?
To be more specific, I've designed a Snooker Hall Management program and want to be able to turn the lights on over the Snooker table when you start a game in an Access form...My application has 8 tables but could be expanded obviously.
I'm happy with the Access side of things (first attempt at a real world solution, etc) but to be totally polished a hardware interface to control the lights would really create a 'wow' factor...
Any help or direction would be greatly appreciated :)
Regards

I want to have a MS Access 2000 database open, load a Form with various option buttons on and get Windows Media Player to play a MP3 music file. However, when I click a option button on the Form I want the music to stop.
Any ideas of code to do this?

BACKGROUND
The current challenge I have in MS Access in really giving me a headache. I can’t seem to find an answer or indeed think “outside the box” so I am hoping there is someone who can help.
Below I will outline the design of my database, the problem I have and my proposed solution. My solution is “What I want to do” rather than “How I do it”. If you have the time and patience to look at my problem and suggest how I proceed, I will be really grateful.
CURRENT DATABASE DESIGN
I created a database that imports daily telephone data. The design below is a simplified version of the real thing but it contains the essential information needed to understand my database.
I extract data from the phone system for “Lines” (3 digit code) e.g. ‘301’,’302’ which each have a corresponding line “Description” e.g. ‘New Customers’, ‘Accounts Queries’. There are three main daily extracts (1) Inbound Calls (2) Outbound Calls and (3) Time. Each extract has either “Line” or “Description” as the unique identifier but not both.
There are 50 lines with matching descriptions and each is allocated to one of 20 teams. I have a query which links all three extracts, groups the data by team and date. Therefore this query creates 20 records (teams) for each day (date).
CURRENT QUERY AND TABLES
Tbl Line Lookup (50 records)
Line
Description
Team
Tbl Inbound Calls
Line
Date
Offered Calls
Answered Calls
Abandoned Calls
Tbl Outbound Calls
Description
Date
Outgoing Calls
Tbl Time
Description
Date
Answer Time
Abandon Time
Talk Time
Wrap Up Time
Qry Grouped By Team Daily
Line – linked to line in Tbl Incoming Calls
Description – linked to description in both Tbl Outgoing Calls and Tbl Time
Team – Grouped field
Date – Grouped filed
Offered Calls - Sum
Answered Calls - Sum
Abandoned Calls - Sum
Outgoing Calls - Sum
Answer Time - Sum
Abandon Time - Sum
Talk Time - Sum
Wrap Up Time - Sum
PROBLEM
Customer Services “Team” is made up of six lines (301-306) and Business Partners “Team” is made up of three lines (307-309). For each day my query creates a record for each of these teams based on how the line is allocated in Tbl Line Lookup.
The business had decided that line 304 calls are part of the Business Partners with effect from 01/05/06. If I change the team name associated with 304 in Tbl Line Lookup this will, incorrectly, allocate all information (from 01/01/06 to present) to Business Partners.
I need a mechanism to allocate 304 to Customer Services prior to 30/04/06 and to Business Partners after 01/05/06.
PROPOSED SOLUTION
I want to introduce a new field in Tbl Line Lookup called Effective Date.
Tbl Line Lookup (50 records)
Line
Description
Team
Effective Date
Then I want to introduce a new query which links the data in the three data tables and allocates the correct team name by comparing the date in these extracts with the effective date in the Tbl Line Lookup.
I would then run my original query (Qry Grouped By Team Daily) over this query instead of the original tables.
Please can someone tell me if it is possible to look up values in another table to determine the value of a field in the way I have described?

Hi,
This is what i want to do:
Have a button on a form that when pressed opens a file browse, allows you to pick a text file (May contain different values and in future the structure may change slightly), then import the text file contents into a temp table (2 fields, Setting & Value), then run a query to take different values from the temp table and put them in to different fields in to different tables linked to the same main record where the button is, then save the record and all linked tables data, and then delete the temp table, and display a message box saying something like done.
Each import file will be a single record, but has to many fields to be in one table
I also need to extract only part of Field 1 (Sample Below), the part after the = (150 in below)
0x6A,0x10,0x12 = 150
Thanks
Dan

Many will look at this and laugh but its real.
My Access Dbs are opened in hidden state and i dont see my forms.
This must be the cause.
I tried to hide the menubars using ghudsons code,i disabled the shift key. But i dont know what has happened.
I can nolonger view them. I have tried every method out and i think the only option is to repair OS, may be it will work.
I have enabled the database which i disabled the shift key but when i hold down the shift key, it loads but the forms are totally hidden, STRANGE! ijust see the grey access background and when i click on it twice from the task bar.It pops up.
I have tried to make another database, use the autoexec macro to call a form which enables all command bars, but this works only for this database and when i press the shift key down, this database hides the toolbars and i only see the grey access background. This is happening on EVERY DB ive developed on this machine. I thought it was the access that is totally corrupted but i tried to reinstall my office and i still get the same results
This is now a NIGHTMARE to me.
When db is shifted to another machine it works fine as before.
This is REAL but can i get some suggestions from you folks before i repair my OS.

trying to join two tables but get message
"relationship must be on the same number of fields with the same data types"
data types are same, numbers.
Primary table has just jobnoID that are all unique (primary table)
ie 6907, 6908, 6909 etc
second table "jobs by order" (secondary table)
has
unique orderno(order numbers) in column one say 69071 and 69072, 69073
and jobno in second coloumn say 6907, 6907, 6907 for all the above.
trying to link JobnoID primary table (one to many) to Jobno secondary table (many)
Also need to note. This database is a purchase order database. so am trying to load in all past data from excel. data is in already. so primary table above with jobno is an auto number so will generate the new jobno for us. but had to copy and paste blank fields into table to get records upto the number we are upto now, ie job number 7112. I have only put data in secondary table for
jobno's 6885 through to 7112, and even some of these have blank spaces.
Any ideas?
Also how do i do a screen capture and dump in here so you can see relationships etc, which would be a whole lot easier to explain. thanks heaps

I am building a database for a Real Estate business.
I have 2 tables tblPurchasers and tblVendors.
I intend to write a query that will match the requirements of the purchasers to the properties for sales (from the vendors).
My issue is this (best illustrated via an example);
I run my Query on the 1st April and four properties are produced as being suitable for purchaser 'A'.
Purchaser 'A' immediately deems properties 1 and 2 unsuitable and views property 3 on the 6th April. Property 3 is subsequently deemed unsuitable as well.
I re-run my qury on the 10th April and five properties are produced as now being suitable for purchaser 'A'.
Purchaser 'A' has already dismissed properties 1,2 and 3 so i don't want to show him these again ....... how do I just ensure that properties 4 and 5 appear ?
Purchaser 'A' has already dismissed properties 1,2 and 3 so I don't want to show him these again ....... how do I just ensure that properties 4 and 5 appear ?
Something involving a yes/no box on a form would be the best method for me of implementing this (as it would fit in with the scematic of the database to date).
I imagine the properties (with a small photo) appearing and tick boxes headed 'Unsuitable', 'Viewed' etc be used to dismiss properties, which do then not re-appear.
MANY THANKS !

Detailed search cannot answer my time problem. Returning after long break in programming, I am trying to create a form to display TimeIn and TimeOut fields such that actioning an OnClick command (or separate tick-box), TimeIn field will hold current time for that record. Need to set the same for a TimeOut field. Both cases time always to be < 24 hours.
Am so rusty on MS Access putting default value as =now() produces an error!!
Any basic help to wind up the old mind always appreciated.

Hi:
I try to get the value in a real time. There are two subforms inside a mainform. First user enters value into mainform. Than comes to subform1. And after that on the basis of a choice in subform1, the 2nd subform is open. In 2nd subform i create a listbox with that query.
SELECT [tbl_Events].[PPVVOD_Outlet] FROM tbl_Events WHERE [tbl_Events].[ticketnum]=[Forms]![tbl_PPVResearch]![ticketnum];
But it shows empty. [tbl_Events].[PPVVOD_Outlet] is a subform1

I have a form. In it is a status field that can be:
NEW
SENT
CREDIT
COLLECT
CLOSED
When the item is created, it is given a "NEW" Status. And there is a command button on the form that can change the status to "SENT". However, based on external factors (email received or system report examined) the user can manually change the status to the CREDIT, COLLECT or CLOSED. Now, I want to make sure that then can't change the status manually to "SENT", only the system is allowed to do that via the command button.
How can I allow them to use some of the allowed values, but not others?

History:
MS Access 2003
Database up and running over 5 years
Compact and repair daily
250 end users
Security screen with log on to database
Problem:
User signs on and everything runs smooth, then all of sudden can’t access some reports or forms. I call our IT people, usual fix is resetting the profiles. Now sometimes this works and sometimes it does not work. This problem just started a few weeks ago. I try to isolate the problem. I sign on his computer and have no problem. I have the user that is having the problem to sign on another computer same thing, he has problems. So to me it’s the user profiles right?. The IT people think it’s the database. I have tried about everything I can think of, but still have the problem. Also all the other users are up and running fine.
Now the only thing that I can say is, that we are getting up dates from Microsoft on a daily bases now. Our IT people would run them at night instead of during day. Do you think that could do anything to the database? I have spoken to them and they mention its security updates.
Can you give me any other direction that I can go? We are going to have a big pow wow meeting next week, I’ am trying to have something that I can go on.

Howdie y'all
I need a few pointers wrt the relationship between a form and its subform.
I have the following form:
http://i88.photobucket.com/albums/k193/bernmc/Misc/DefaultStaffingscreenshot.jpg
Top part of the form is for adding/editing etc.
The subform is based on a query. The two are linked on the 'week' value.
Now, this is what I want to do:
The user must not be able to edit data in the subform (so should I use a report instead... but then will I be able to do 2...).
Selecting a row in the subform should cause the whole form to go to that record so that the user can then modify info in the fields of the main form.
I don't know VB - the only code I've used is gleened from searching these forums (a great resource, so I'm learning slowly), so I'll need a bit more than 'Do a wrzmitchigob on the bleedlethrop'!

My report has the Section's Footer.
Each time the section runs, it will take up a different amount of space.
I have already run all the code, to move all the different controls to the top (and be invisible) when they are not needed.
So to the best of my knowledge, I have no controls sitting in the lower part of the section.
The last thing I run is:
Code: Me.S123.Height = Me.S123.Height - 300
s123 is the name of the Footer SEctions. The idea is that it gets progressively smaller.
This is all running in:
Code:Private Sub S123_Format(Cancel As Integer, FormatCount As Integer)
All the other things work.
Here is a sample of it all..
Code:If Me.txt2 = 0 Then Me.a2.Visible = False Me.b2.Visible = False Me.a2.Top = 0 Me.b2.Top = 0 Me.box.Height = Me.box.Height - 300 Me.S123.Height = Me.S123.Height - 300End IfIf Me.txt2 <> 0 Then Me.a2.Visible = True Me.b2.Visible = TrueEnd IfIf Me.txt3 = 0 Then Me.a3.Visible = False Me.b3.Visible = False Me.a3.Top = 0 Me.b3.Top = 0 Me.box.Height = Me.box.Height - 300 Me.S123.Height = Me.S123.Height - 300End If
This runs through 8 different numbers.
as I said, all the other things operate properly. They get hidden and move.
Any thoughts?
Thanks.

Greetings!
Hoping somone could help me here.
I am trying to create a database (duh!). At the moment, I have two tables. One table is a small timetable with the fields:
Day, Airline, Flight Number, Time, Origin, Destination, Aircraft
The other table (Delay) has the following fields:
Date, Day, Airline, Flight Number, Time, Origin, Destination, Delayed by.
I would like to do the following. In Delay I put in the date: 01/07/2005, fine. The Day (field format Date/Time dddd) is also 01/07/2005 which Access transofrms into the word "Friday". Airilne is BA. In Flight Numbers, I want the database to do a query on "TIMETABLE" to search all flights that operate on a Friday as some do not operate daily. (By the way in the 'Day' column of Timetable the values are "Monday Tuesday Wednesday Thursday Friday Saturday Sunday" or "Monday Thursday Saturday" depending on the flight). This query/lookup should be performed right after I type 01/07/2005 in the "day" field of "Table: Delay". A lookup combo box should be displayed when I arrive at the field FLight Number. I select a flight (e.g.: BA001) and automatically the Time, Origin and Destination of the flight should appear in the "Table: Delay".
I have been unsuccessful at even getting past the first hurdle. I tried a query of the "Table: Timetable" and fields "Day" and "Flight Number". The Criteria I do not know what to put in. "Like [Delay]![Day]" or "[Delay]![Day]" does not help and brings up nothing. However, "Like *Monday*" does bring up all the flights which operate on a Monday. However isn't there some way of telling the query to automatically occur after I type in the relevant day in the "Delay" table? Futhermore I would like to avoid (but not totally exclude if it's impossible) macros as eventually I hope to publish this to SQL or whatever.
Cheers in advance.

The queries go like this at present :
SELECT TOP 1 [Table].[QuestionText], [Table].[Answer] AS CorrectAnswer
FROM [Table]
GROUP BY [Table].[QuestionText], [Table].[Answer], rnd([IDQuestion])
ORDER BY rnd([IDQuestion]);
SELECT TOP 3 Table.Answer AS Correct, qQuestionTextAndAnswer.QuestionText, qQuestionTextAndAnswer.CorrectAnswer
FROM [Table], qQuestionTextAndAnswer
WHERE (((Table.Answer)<>[qQuestionTextAndAnswer].[CorrectAnswer]))
ORDER BY Rnd([IDQuestion]);
These queries are displayed now in an Access form "frmQuestions" which is applied to "Table" that has three columns id, text , and answer. The result is one question and four suggested answer with one only being correct.The arrangement of the answers is randomized--
but the choice of the question is not realy random....it always starts with the same question as it relies only on rnd.
can I improve the queries and randomize and rnd in the same ...or else can I switch these queries to be used from vb6 code and achieve that result.
any help would be appreciated.
By the way I am really a beginner at this who is seeking help from the experts.

Okay, seems like it should be simple... maybe I'm wrong though:
Any one know how to do real-time counting of the number of characters in a text box so that once it reaches 3 it automatically moves to the next text box? (Doing a phone number ... area code (int) and phone (long) to make for a total of 6 bytes.)
I've tried several versions of code for the on-change event but I can't seem to find the right way to assess the number of characters currently in the control... I'm pensive about setting an invisible control to just 'count up' because the on-change event would stack it even with a deletion. See most recent attempt below...
Obrigado,
~Chad
Private Sub txtAreaPhone_Change()
Dim bytCount As Byte
Dim strAPhone As String
If IsNull(Me.txtAreaPhone) = False Then
strAPhone = Cstring(Trim(Abs(Me.txtAreaPhone)))
bytCount = Len(strAPhone)
If bytCount = 3 Then
Me.txtPhone.SetFocus
Else
End If
Else
MsgBox "This is Null"
End If
End Sub
