Problems With A Linked Database
Aug 16, 2007
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 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.

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!

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?

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?

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

Hi,
I have an Access 2000 database with some linked tables. When upsizing the database I selected 'Save password and user ID with attached tables'.
Therefore in the Linked Table manager after each table in brackets I have the name of the database to which the tables are linked.
I am now wondering if I want to link the tables to a different database how do I change the database name, which is in brackets after the table name.
If I select a table and select 'prompt for a new location each time' I am getting prompted to select a different DSN. At the moment I don't have a DSN and I don't want to have to set one up.
I imagine that the database name and the user id and password I entered in the upsizing wizard are stored in some configuration box but I don't know where I can access this.
Can anyone point me in the right direction??
Thanks

Hi,
My access database's tables are currently linked to an excel document. My question is, how do I move my database to the network? Currently when I move the the database to the network no one can open my tables because the link goes to my documents on my computer which they can't access on the network.
So how do I move the database and maintain the link between the database and my tables?
Thanks in advance,
Ryan Smith

I have been working on quite a few multi user Access projects in the past few months with a backend and a front end which has linked tables.
I would like to know if there is any way to find out the source of a table linked to the front end and where would its location be on the network.

I have a report in Access 2010. The report contains some images in the main report area and in sub reports. I have The queries that feed the report and subreport contains the name of the pictures that are loaded into its image controls. I added the following code to my form in order to control what image is displayed for each record. Id like the form to work even if the database is moved as long as the subfolder and photos are moved along with it (thus using relative path).
Code:
Private Sub Report_(Current)
Dim ImagePath As String
Dim ImagePathInt As String
Dim ImagePathPlanV As String
[code]...
The problem seems to be that the routine doesn't seem to initially recognize the path. I have a blank photo in the folder containing all the images called NO PHOTO.jpg. If I open the report in design view and browse to this image in the picture parameter of any one of the image controls and run the report, then everything works perfectly even if I close and reopen the report. The report shows the right pictures even in the subreports.
The problem is when I close the database and reopen it, then the link is lost again, forcing me to do the process of browsing for the NO PHOTO image again. I already try to do an open form procedure to automatically reset the picture property, but although it resets the picture to the picture I set (I verify this by setting a different picture instead of the NO PHOTO) it does not make things work correctly as it does when I manually browse for it in design view. I also try to run the code above under the Report (Open) instead of the Report (Current) but that didn't work either.

Hi.
I'm about to move to a back end / front end system, from a single database file. Before I do so, I want to make sure I have all bases covered so to speak.
My back end file will reside on a server. I am aware that path names are sometimes changed by network administrators without warning.
From tests, I notice that, if the path to the back end can't be found, one cannot open the front end database file at all (Access 2003).
My question is: if my back end file gets moved, or the path changed, how can I get into my front end file to update the linked tables.
Many thanks in advance.
Mat.

I have built a database and within it my queries I use for reporting make tables in a separate database. This allows me to work in my data base and update info as needed. My problem is that my make table queries wont run if anyone has one of the report pivot tables open. I have added macros to all the Excel files that pull from the reporting DB but I still have several times when I cannot update because someone is using the pivot table, Is there a way to allow me to update the report DB's while the pivot tables are open? I have tried using manual refresh methods and disabling auto update on open but the result is the same.

I recall reading somewhere (fairly recently) about a parameter or property in Access which is "On" by default and allows a form/query to identify when backend table field names or query arguments are changed and automatically looks for and "fixes" the renamed link. By leaving this switched ON, the database is slower than it could be. The db speed performance can be can be improved significantly by switching this 'feature' off. (i.e. Name of the property)

I have a question that I have a Microsoft Access database (.accdb) front-end/backend split and I want to give the database to my company client. As we have the different path for the backend/frontend linked. I want some code that will popup if the database location is not found and popup with the dialog so the user then select the backend and it would be ready and there is no need to popup each time the database open, it would run once it did not find the last linked path.
Also I have tried the code of Dev Ashish URL.... but unfortunately it would ask everytime to refresh the table links and I only want to run the process of linking tables when the database start and the linked path not found.

I have MDB database linked to SQL SERVER through VPN connection.I created links to the sql server Links are dsnless..Everything works fine but when I lost VPN connection or sql connection has been broken I can't refresh links to the tables.I receive message 3146 sql connection failed..I must close database and start again...
I tried different methods like ado,dao, and vba docmd.transferdatabase,aclink... but no success, table cant be relinked.
Only way I can relink is to change ip adress in conn.string
E.g. 192.124.0.2 (1st ip- router server ip) and after connection failed i can use 192.124.0.32 (2nd ip - server local ip) and that's it if i lost connection for the 3rd time... i must restart application.
It seems that access database keep the previous connection..how to reset or drop database connection to the sql server and refresh links to the tables with vba code without closing access database...

I have a database with a number of linked tables that are linked to tables in different databases (not a back-end).for example, I have table1 that is linked to table1 in K:databasedb1.mdb.table2 linked to table2 in S:datadata.mdb.and so on...
However, recently we have moved all our databases to a new location.
K:databasedb1.mdb is now residing in O:masterdatabase
and S:datadata.mdb is now residing in O:masterdata
and so on...
I'm now in charge of relinking all those tables to point to the new location.I would do this in linked table manager one by one but we have 100s of tables linked to multiple different databases in different location.is there a way to create a VBA code that will automatically do this re-linking process?
so,
1. find unlinkable tables
2. search its new location under O:master
3. re-link it to the new location
Database names and tables names have not been changed. Just the location of databases.

looking for a way to export the list of table names, table types & if they are linked (e.g. tbl Sales Linked .dbf or tbl Staff linked to excel) from a database - this has to be done for about 300 databases.
in an individual db, I have a make table query off of the table MSysObjects to get the data. The Database field tells me where the source of the linked table resides & the ForeignName field gives me an idea of the format of the data source (e.g. dbf or excel). I could manually import that query into each db, run it to get the table names, then copy & paste..

I am trying to build a Form that will show an estimate (then eventually will be moved to a project if customer and employee aggree to price and project) in a Form F_Estimates is a M_Customers(Customer_ID) (Based on a Table) and thier info in a Subform. Also is the "projected costs" from parts out of the Parts(Part_ID) (Based on another Table) in a second Subform as a list that I need to calculate $$$ in
(Dang that still sounds evil and definately NOT understandable even after edit... so)
Here's some basic info
Tables
EstimatesandParts - Table
EstimatesandParts_ID : Autonumber
Estimate_ID : Number
Part_ID : Number
Parts - Table
Part_ID : Autonumber
PartNumber : Text (not a number due to some part#s have letters in them)
PartName : Text
Unit Price : Currency
Description : Text
Estimates - Table
Estimate_ID : Autonumber
InvoiceNumber : Text (again can have letters in it)
EstimateDate : Date/Time
EstimateTime : Date/Time
Employee_ID : Number
Customer_ID : Number
ProblemDescription : Memo
Customers - Table
Customer_ID : Autonumber
FirstName : Text
LastName : Text
CompanyName : Text
Address : Text
City : Text
Province_State : Text
Postal_ZIPCode : Text (CDN Postal codes are letter num letter...)
you can see the link table in the EstimatesandParts Table
Now I want to use that link to populate a subform in the F_Estimates form
Forms
SF_Customers - SubForm
(all boxes atm are text boxes on this form till I figure out the Parts section then will use same base for this so I can pick any customer in the database to be the customer for this estimate. Also will have ctrl button for making new customer with customer form and a refresh on Focus Gain bit of code)
FirstName
LastName
CompanyName
Address
City
Province_State
Postal_ZIPCode
SF_Parts - SubForm
Default View -Continuous Forms
(want it to be a list of parts that I can grab prices and descriptions from then in a bit of code to calculate a cost of parts)
Part_ID : Combo Box
Control Source - Part_ID
Row Source Type - Table/Query
Row Source - SELECT Parts.Part_ID, Parts.PartNumber, Parts.PartName, Parts.UnitPrice, Parts.Description FROM Parts ORDER BY Parts.Description;
(Pulls info from the table Parts for input into a list of parts to be used on that project)
PartName : Text Box
UnitPrice : Text Box
(here's where I run into problems due to the fact that the form is not based on the parts table but rather the link table EstimatesandParts so I can't propogate the info to the 2 other text boxes, ps I dont care if they cant be text boxes and have to be linked or some other type I'm not "set" just need to find out how to make it work )
(have tried a couple things to complete this task)
Me.txtPartName = Me.Part_ID.Column(2)
Me.txtUnitPrice = Me.Part_ID.Column(3)
(works AWSOME ... for ONE ROW then propogates the second selection to the first and second and third selection to first second and third and so on ...)
(tried to make control source for the txtPartName to)
=Forms!Parts!Partname
(Doesnt exist .. akkk, cant use ActiveForm either as it doesn't focus on the SubForm but the MainForm ... cry)
F_Estimates - Form
Estimate_ID
InvioceNumber
EstimateDate
EstimateTime
ProblemDescription
(all basic Text Boxes)
Employee_ID
Customer_ID
(Combo Boxes Select Customer and Employee from list of present ones of each)
SF_Customers
SF_Parts
(Both SubForms on the main form)
Now this is an Exerp from my entire Database I like to work on one small problem at a time and I have made this its own little database till I figure out the problem then I will bring the info I learn back into the rest of the database and go from there ...
Hope you can help I have a feeling I will need to make a recordset and go from there but I'm just not able to wrap my head around that for some reason
Thanks in advance for ANY and ALL help that I get from here

I have a database with the tables linked from another database. The problem is that i need to copy the database to and from another machine in order to work on it. As this involves putting it in a different location each time, i have to relink the tables.
Is there a way to link the tables reletively so that as long as they are in the same Directory they will be linked?
