Working With Linked Database
Feb 6, 2007
I am slowly but surely learning more everyday about Access. I inherited a database system from a gentleman who set up a lot of great stuff but did not document anything! I am working with a linked database in Access. I am trying to add information to a look up wizard. I am unable to de-select the "Enforce Referential Integrity", so I deleted the one to many relationship in hopes of being able to add the information. However, I am still not able. A message pops up stating it is a linked table and some properties can not be modified. My look up wizard Row Source can not be modified.
Any tips on how to get around this?

Hi,
I have to make changes to a report that is built from a linked table that the team is using constantly. I don't know this application well at all and its going to take some analysis. How can I work with the table w/o locking the users out of the table.
Thanks for your help!

Our database is 1.6gb in size.
It has stopped working, is there a way to delete old records?
We are told it will crash the computer, because access needs the same space as the data its self.
Any ideas?
Thank you for your time in reading this post

Hi.
I am having a hell of a time trying to make my order and invoice processing database to work properly with useful functions. Is there any online resource from which I can download a working example of such a database in order to use as a case study and examine how everything relates and how complex order forms are created? :confused:
Thanks.

Hi
Many thanxs for replies, Like the idea of compacting.
We are traveling down the path of setting up a delete query.
This will hopefully delete the records but not the structure.
We are networked and a computer Warp2, writes data at Midnight to the sever, and then we use access on Windows NT to view the data.
We can then compact to maintain the database and not allow it to grow to 1.6 GB again.
Any ideas on the delete query thingy would be greatly appreciated.
:cool:
Many thanks for reading this post from a new starter.

I am having a problem that I have never encountered before and thought I start here. Using Access 2003
I have a database that resides on a main computer and my users connect via the network to this database. On my forms I have command buttons that run simple macros to copy and paste data from one field into another. The macro contains a GOTOCONTROL, to copy the contents and then moves to the next field. Then I have SEND KEYS command and wait is set to yes, then PASTE. When they press the command button it seems like the SENDKEYS is not waiting then the macro halts becuse it is saying the COPY command is not available. This happens to all users except for one. That other user is also connected to the database via the network. I checked the OPTION for all the computers that are connected and they all match to the one computer that works. The one computer that does work is the one that was used to write the database but the databse is now on another computer that is always on. The funny thing is that if I were to change any option under Forms/Reports, the macro's will work for a while then stop. I did do a compact and repair several times but this has no effect. Sorry for rambling but I am just frustrated because this databse worked fine at another account of mine and I just can't figure out why this is happening.
Thanks in advance for your reply.
I now haw 2 laptops that work and 2 desktops and 1 laptop that don't.

I was recently asked to document all our applications and databases. Is there a way to tell what is linked to a database?
I know how to tell what the source of a linked table is. I'm looking for a way to look in reverse.
example. Database1 is a storage database of all our personal data. Database2 through database100 is linked to database1
Can I go into database1 and see what's linked to it?
Thanks.

I created a database which had to be split to allow multiple people to access it with three 'front-ends' so that different people had different levels of access. Due to security problems this database had to be moved to another location on the network. Now I have used the linked table manager to update all of the frontends so they can locate the data. Previously users would just copy their own version, appropriate to them, and use this to update; now though only one person can open the database at a time with the backend database being opened and hence locked (if that makes sense).
Any suggestions as to why this has happened, or solutions would be appreciated.

What is wrong with this linked pictures in my database?
I have made OLE field in a table and I want to insert pictures in that
field with option "linked". But pictures are not exactly linked. First, they take
a lot of space in a database, almost as inserted pictures (If inserted picture takes 30Mb than linked picture takes 20Mb). I thought it is only going to save a link (target location) to a file. Also, when I insert link to a picture ina OLE field and delete this picture in windows - I can still see this picture on a form in my application. So, is it linked or inserted (only difference is that I can't edit linked picture if it's deleted in windows but I can see picture in a form).
How can I insert only link to a picture in my database so I can see pictures in forms and reports and pictures stays only in windows and takes a minimum space in my database (only for a target informations)???
Thanks!

Hello. I created two databases on my personal computer at work. One is called "Main" the other is called "Link". As you might have guessed, I linked the tables from "Link" to "Main" and imported the forms that were in Link into Main. On the opening page of Main, users click either a button that takes the into Main or a button that takes them into Link. On my computer, it works perfectly. However, when I went to put the database on the network drive, i get error message 3044, invalid path. This is probably something minor, but I am new to MS access and am stuck. Thanks for any help in advance. BTW, the company is still running 97; i dont know if that changes anything.

I have searched through a number of threads trying to find a solution to this problem that I am having without luck, so I figured I would post a new thread.
I have an application in access that pulls data from a SQL database. Users can already delete a record out of the database.
The problem comes when I try to give them the ability to update the information in a record.
First, I went to the tables listing and double clicked on the link table that contains my information.
Once that window opens up, I have tried to change a piece of data on this table, but it give me a 'Write Conflict' dialog box stating 'this record has been changed by another user since you started editing it. If you save this record, you will overwrite the changes the other user made.'
This is the same error if a user changes any information on the form and then tries to move to the next record.
What is set up incorrectly that is causing this problem?

Hello all,
I finally got TreeView to work, by downloading the example database from this (http://www.access-programmers.co.uk/forums/showthread.php?t=80805&highlight=treeview) thread. I haven't had as much luck with ListView, though. Does anyone have a database they could post that has a working listview? I'd greatly appreciate it!!
Thanks,
Eric

Hi! I work at a company where a same DB is being opened by more than one user, is there any way to allow many users be working on a same DB?
Actually I cannot even open it if its already opened. It appears another file with a "lock", which seems to be protecting the DB. :confused:

I am working on developing a database that develops requests to send to another department. There are a lot of forms, macros, reports and queries. A user inputs information into a form, and then selects a command button that is attached to a macro that builds the request. Midway through the build, another form comes up to complete missing information. I was going along just fine - at the testing stage for this part of the process - when the database stopped working like it should. Some of the issues I am seeing:
1) If you open a new query and try to close it without saving it, it just keeps asking you if you want to save over and over even though you select No.
2) If you open an existing query and make a change, it closes it and saves the changes without any prompting at all.
3) Macros and forms do not work right. I have a macro that deletes the records from one table. The form for that table now shows #Deleted in all the fields instead of blanks.
If you compact/repair the database is good for one run through but then it doesn't work correctly again. I have had this issue in the past but have no clue how I break my databases! I have a general knowledge of Access, I am not really a VBA coder if I can avoid it at all costs. There must be something in the relationship between all my tables, queries, forms, etc but I have no clue even where to start to troubleshoot. HELP!!

I created a database a while ago which has been working just fine, until I wanted to make one addition: an attachement field to one of its tables.
If I do so, some queries don't work anymore and as a result of that, some (sub)forms do not work. The only error I get is: The search key was not found in any record.
When I add an other kind of field (like a text field), the problem does not occur..
When I remove the attachment field again, everything works fine again...

I have an Access 2007 database which has a form on which is a button to dial the currently selected phone number. All works fine. My intention is to send out partial databases to people not having access installed and they will use the access runtime module.
When the same database is run using the runtime it does not dial and does not give an error message. It just stays the same as though I didn't press the dial button.

Dear All,
I have a property database linked to ArcView 3.1. It has a field that links to the ArcView Database called ID which is unique and set to a data type of double.
I have a further form that can go straight to a record if you know it's ID.
This form works fine so long as the ID field is no more than 5 digits. I have a series of polygons that have six figure ID's - the link to arcview works fine using these six fig ID fields however the form that looks for that particular ID can't cope with the six figure numbers...
My problem is although I could change all the ID's of the records in the Database so that the search on ID worked (ie five figure id) they then wouldn't match with the overlay in ArcView and I would not be able to link through using code without first changing and matching all the codes associated with the polygons (time consuming)
I did try changing the datatype of the ID field to long integer but still have the same problem. Strange that the search works for five figure IDs and not six.
Does anyone know whether this is a data type error or is it some simple oversight.? I can probably work out some way of changing all the ID fields to five figures but would prefer to keep the six figures as they are used in some pre-printed material as refs
Thanks in advance
Mark

Hi,
I created a database in Microsoft Access and then upsized it to SQL Server afterwards.
I now need to add a new column to a table in the database. So I added the new column in SQL Server using ALTER TABLE command. This column is a foreign key which has an associated parent key in another table which contains a description of the column.
e.g.
Main_Table
Case_ID Foreign_Key_Field_ID
1234 78
New_Foreign_Key_Table
Foreign_Key_Field_ID Foreign_Key_Field_Desc
78 Describes the ID 78
I also setup a CONSTRAINTREFERENCE between the fields in these 2 tables.
I then relinked my tables using the Linked Table Manager to pick up the change to the table I altered (Main_Table). I also linked to the new table I created (New_Foreign_Key_Table).
My problem:
In Access if I create a new table I can select the lookup value for a field in the Table Design view Lookup tab. However, I altered my table in SQL Server and then linked to it again to pick up the change. Now when I view the linked table in Access it does not have any lookup value AND it's not possible to change this for a linked table.
Is there some piece of SQL I can use in SQL Server to change the lookup value for the field in my table OR have I approached this the wrong way. Should I have modified the local table in Access and upsized it again?
Otherwise if I select all values from my Main_Table in a form it displays the Foreign_Key_Field_ID instead of the Foreign_Key_Field_Desc because the lookup value has not been set to Foreign_Key_Field_Desc
This posting is a bit long - I hope it makes sense.
Any ideas or suggestions would be greatly appreciated.
Many Thanks

Wondering if anybody has any information about this.
Backgound information: My access database information comes from a 'card' where somebody has manually put crosses in a number of boxes. This information is currently being manually inputted into the database...
I know you can get scanners to pick up information from a document...but is this possible with microsoft access?

I can edit/open existing linked tables (to Sage Line 50, v12) but not create new ones.
Following the procedure:
- New
- Link Table
- File Type: ODBC databases ()
Nothing now happens!
I can open the Link Table Manager to update previously created links.
Any ideas?
I'm using MSAccess 2003 on a brand new machine.

I have a database that links to an excel sheet and take data from it. For a fail safe i put deletes in several places in case of user error to make sure the sheet is deleted. If it is already deleted the other deletes don't act well.
I need to write a conditional iff statement that if it doesn't exist it ignores the delete call. Not sure how to structure it.
Private Sub Command3_Click()
DoCmd.DeleteObject acTable, "Sheet1"
DoCmd.Close acForm, "District Select Form"
End Sub
