Linked Fields Changing On Their Own???
Dec 3, 2007
Hello all...
I have a problem with a single query I have build in Access 2000. Basically, I have a normalised database structure to 3NF. I have a table called Data, a table called Reports and a table called DataReports which cotains the primary keys from both data and reports which are named Data_ID and Report_Id.
Basically, what is happening is I am building a query that returns a record from DataReports using the Data_Id field as criteria as this is held on a form. I create a one to many relationship from the Reports table to the DataReports table using a link from one Report_Id to the other. I save the table and it works fine...once only!! The query is used to feed a list box on a form. The form loads correctly but when I go back into design view to make a change to something else on the form and then go back to form view, I get Data Type Mismatch error. When I look at the query, Access has changed the link from the Report_Id --> Report_Id to Report_Id --> Report_Title which is the next field down in the Reports table. Because all ID's in my database are Autonum's it is trying to link a number to text so I understand why this would not work but I dont understand why on earth access is changing my links. It is very frustrating. Could anyone help me please.
Thank you kindly..
Gareth

Does anyone know how to change all linked tables in a database to unlinked? I want to save a database for offline testing and want to save the tables as flat tables instead of linked. Is there anyway to do this without bringing them all back in unlinked?

Hi Guys,
This is one of this only times i've had a problem whose answer i couldn't find on this or other forums, so here's the question.
My DBase links to the back end tables
tblBrkdn
tblBrkdnArchive
tblBrkdwnTradespeople
tblBrkdwnTradespeopleArchive
The following two tables are local, not linked
tblBrkdnArchiveTemp
tblBrkdwnTradespeopleArchiveTemp
After running through the following code, all of the four above mentioned linked tables are now local. It's vexing. I'm terribly vexed. If you can help, my status would chnge from vexed to joyous....:
Thx in advance...

I need to update the names of my ODBC linked tables in my Access database, how can I do this without causing issues with my queries/reports?The current linked tables are to a SQL View on a database called mcsrm_live, and called e.g. vwDamagesReportNew
The new SQL views that I need to link to are identical in structure and content and on the same SQL server but different database - forkdw and are called e.g vw_R_Damages
Is there a straightforward process to do this without affecting the queries and reports in my Access db?

I'm trying to change the table links to a password protected BE DB. I found an example online, which I adapted to my needs. When I set it up to fail to find the normal BE it seems to work as intended until it gets to the line "Tdf.RefreshLink". Then it crashes with a 3031 "Not a valid password" error. The code is:
Code:
Private Sub Form_Open(Cancel As Integer)
Dim Dbs As Database
Dim Tdf As TableDef
Dim Tdfs As TableDefs
Dim NewPathname As String
[Code] ....
I can't find any references or example to relinking a password protected table.

I am after a script to change the linked table paths like the following.
It will only ever be the path that is changing not the file name and only ever linked tables
Code:
for each table in tabledefs
if table.path = c:Testing* then table.path = w:Testingfilename
if table.path = c:Jobs* then table.path = w:Jobsfilename
if table.path = c:Quotes* then table.path = w:QuotesNewfilename
next table

I have a number of databases that use ODBC connections for working with linked tables from a SQL database. The source SQL data has been moved to a new server with new sa credentials. I have updated my local ODBC connections to use this new information. However, when I added numerous tables to the databases I checked the box to save the password so that it wouldn't prompt me or other users every time I wanted to use the Access database. Is there a way in Access to change this stored password? So far I haven't been able to find one.

I have linked tables in my db at the moment that rely on user dsn connections to an SQL server. I've been reading about DSNLess connections and want to try convert what i have to have permanent DSNless connections, but the code I've found doesn't appear to be working.
I've removed server specific details where i felt necessary, but when running the code i have it in place.
Code:
Public Sub RefreshODBCLinks()
Dim connString As String
Dim db As DAO.Database
Dim tb As DAO.TableDef
connString = "DRIVER=SQL Server;SERVER=<database ip address>;DATABASE=<

Hi Everyone
I need to change a fields properties on a form depending on another fields data.
i.e. If a user ticks a Yes/No box saying they've done something they must also complete the date they did it. I can't set the date field in the table to be 'Required' as if ther is no tick then it doesn't need to be.
Cheers

Help needed: Large Yes/no tables!
I have a form with names of employees, and different skills that employee has.
It is listed in a form as columns with the employee name in rows, and columns for the skills. The form is in fact really great, but I see that the solution might bring problems in the future because of maintainance issues, and field limitations. I add fields frequently, and the table is growing without me beeing able to control it.
I have organized this in only one table, and used the name of the skill as a field. There is many other tables in the DB, but none of them covers this area.
exampletable:
employeeID | auto
employeename | text
Hireddate | date/time
Fireddate | date/time
baking | yes/no
cooking | yes/no
driving | yes/no
juggling | yes/no
With this solution I get the skillname as a heading, and the name as a column with lots of yes/no values. I love the filter functions, and the form is quite nice...
exampleform:
Employee baking cooking driving juggling
employeeeID1 yes no no yes
employeeeID2 no yes yes yes
employeeeID3 no no yes yes
employeeeID4 yes yes yes no
and so on.
Is there a way to organize this so that the skill name comes in the top row, the results get listed as shown above when the skill is placed as a field value, not a field itself?
I have looked for a solution with many-to-many relations with 3 tables, but cant seem to make it work right. It is especially the form I have trouble creating with the new design.
I have also tried to make crosstab queries with minor success.
Does anyone have a suggestion on how I can make the relations work.
One employee can possess a great number of different skills, and the skill can be possessed by a great number of employees. This is not a difficult issue by itself, the problem is to make the form as shown over.
Thank you, in advance.

Hi
Is there a way of changing the case of text that has been entered in a table?
Want a form to display capitalised names, say, no matter how they were entered. Know that they can be displayed in all caps using >.
Thanks

Hi Guys me again!!
After spending the last few hours searching the forum and net for an answer I have finally conceded again that I need advice
I have a field in a table called DOB (date of birth) this is currently set as a Date / Time field
It did orignally have an input mask for short date i.e 11/11/2011 but i have removed this for now.
On my form (Patients) there is also some code in the after update properties box of DOB to calculate a persons age which is entered into another text field on the form.
What I need is a customised message box if the user enters the date incorrectly i.e 11/11/11 instead of 11/11/2011 alternativley is there a way to change what the user puts in i.e 11/11/11 to 11/11/2011 automatically after udating but keeping the code to calculate the age?
Hope this isn't to confusing...
Thanks in anticipation
Paul

Hi there guys,
I need a little help on a little situation. Basically, my client for my school project wants to be able to see graphically if orders sent to their bookstore have been processed or not. So i suggested a change of cololour of the fields.
Now I have created a Form containing the orders as they are stored in a list box, (both already processed and unprocessed orders), now I want to be able to allow each item in the list box to be either Red (if unprocessed) or green (if processed) so the user can see which ones they need to deal with. Im guessing this would take some VB, but if anyone could help me, I would really appreciate it :).
PS, if you do provide VB could you please explain a little of whats going on as i have to annotate all the code I use and im not too profficient in VB
Thanks a lot
Dan

I've asked this question in different forums before, and though some people say it can be done, I have not found anyone who is successful yet.
I have a report that puts down a person's address, however the address information is stored within the database in separate fields ('Address', 'City', 'State', 'ZIP'). The issue I have is with the City/State/ZIP. Some city names are longer than others, is it possible to have the fields adapt to the different word lengths.
Say the address is, Albany, NY 10023. The database would output this alright, but then if the city name is San Francisco, CA 94143, the fields are in disarray.
I have the same issue with names. Last name and first name are stored separately. I would like to display Last, First. My workaround has been to right-align the Last name, and put it adjacent to the left-aligned first name field. This works unless the person's last name is very long, disporportionately from the first name, in which case, it looks very much off center in the overall report.
Any help would be appreciated.

I have an existing report with a number of fields arranged horizontally in a tabular fashion in the detail section. The first field is an identifying line of text and the remaining fields are numerical calculations. The report is basically a simple profitability estimate report for a number of different products.
Behind the fields of data is another text box that is blank, which stretches across all the horizontal fields, and which changes background color using conditional formatting. When printing, this colors the whole row according to that criteria (it changes color based on the relative profitability of each product in the report).
The problem I'm having is that the first line of identifying text can sometimes overflow.
I've set the Can Grow property to Yes for this and all other controls in the Detail section. But the result is sometimes some funny-looking formatting. The identifier (like "Product XYZ with a really long description") will word-wrap, but every other field in that row maintains their own height. In particular, this makes the coloring of the conditionally formatted row look off, because it provides only one line's worth of color, even though the product description has wrapped to two lines.
How I can resize all the controls in the Detail section based on the height of the tallest control, and keep the whole thing dynamic?
Things I've tried: I've tried putting some VBA in either the OnFormat or the OnPrint events that iterates through the controls in the section and resets their heights. In the "OnFormat" event, nothing happens (no errors and no apparent changes in the appearance of the report). In the "OnPrint" event, I get an error that says the height property cannot be changed during a print or print preview.
The VBA I tried using was as follows:
Code:
Dim ctlIt As Control
Dim lngMaxHeight As Long
For Each ctlIt In Me.Controls
If ctlIt.ControlType = acTextBox Then
[Code] ....

Hello All,
I currently have a bunch of tables that I have linked to a SQL database. For development purposes (easy of use), I'd like to turn all those tables into regular tables rather than linked so if I take the db offsite, all the data is with me. I realize there will be no updates, etc. but that really doesn't matter for my needs in this case.
Is there a script or an easy way to do this? (besides doing a manual import for a LOT of tables)
I've tried searching but I might not be searching for the correct terminology.
Thanks in advance!
Randy

Hi everyone :D
A friend just came to me with an Access related questions that has me curious. I think that I have seen what he is trying to do before but couldn't puzzle it out myself.
Here's the basics, he has two items on his form, the first is a drop down box and the second is a text box. The table that these two items are connected with has 3 fields (auto number, ARS, and description).
What he wants to do is link the two items on his form so that when an item is selected from the drop down box (from the ARS field) it will auto-fill the text box with the information from the description field of the same record.
Hopefully I explained this clearly. Can anyone out there be kind enough to provide direction on how to do this?
Any help would be appreciated!!!!!

Hi all,
I have split a database, then realised that I needed to change two fields in a form. Y/N field and Text field.
I went into the backed database changed the fields to be Required but in the front end it doesn't seem to work? I haven't tried re-linking them but should I need to?

I have two forms linked by a field "JUVIS". My problem is that I can't get the second form to show data newly entered on the first form without moving to another record on the first form. I have a command button on the first form that
opens the second form. All works well, meaning the forms are synchronized,based on the JUVIS field, except in the case of entering new data. In this case the second form opens to a blank screen instead of showing the JUVIS field. The forms are both linked to tables not to queries. Any help would be appreciated

Hi, I am trying to make a list box that shows the first name of different people in the same family in a subform. I have the first names in different fields linked to the same ID, and the list box I keep making that sort of works will show the whole row of names (but also everyone else's first names down the list), and it will only keep the first name in that row when I select it. I would like to know how to make a list box that just shows the 2 or 3 first names linked to the last name or ID that is currently on the main form I am looking at.
Thanks,
Rod
