How To Conncet Access Be Tables Using Vb Code
Dec 28, 2004
Hi,
I need to know is there any specific code that would establish link for tables from Access BE?
I know it using Get External Data...Link Tables. Even though they are in other db but it leads to increase heavy size of main db. I want no table objects (except system tables) to be displayed in main db and only link tables once main db activates and should no table remain exists in FE after closing.
There should be some way to establish connectivity of tables from Access BE at the time of opening main db . This will help a ton to reduce the size of main db and its zip file can be copied even in a 1.44 mb floppy.
I heard something about shell but exactly I don't know how to do it.
Any idea....
With kind regards,
Ashfaque

With rs
Set .ActiveConnection = cn
.Source = "SELECT * FROM ITEMS"
.LockType = adLockOptimistic
.CursorType = adOpenKeyset
.CursorLocation = adUseServer
.Open
End With
'Set the form's Recordset property to the ADO recordset
DoCmd.RunSQL "INSERT INTO ITEMS(ITEM_CODE, ITEM_NAME, ITEM_CATEGORY) VALUES('" & ITEM_CODE.Text & "','" & ITEM_NAME.Text & "','" & CATEGORY.Text & "')"

Using an example:I have three tables; tbl_weight , tbl_height , tbl_bmi...How do I make tbl_bmi automatically use the weight and height values (height/ weight) to determine the tbl_bmi values? Is there a way to store code behind the tables as if I was in MS excel?

Credit goes to FoFa for posting this code on this form.
Attached you will find code to relink tables. I manage I am doing to wrong, and need help in order for it to execute correctly. I would appreciate direction.
What I am doing:
Copying the modules over to my unsplit database.
Creating a form called ReLink.
Setting a macro (AutoExec) to open the the form.
On the form's On Open event placing the function =TestIt
Splitting the database.
Verifying by opening FE that connection exists
Moving BE and reopen FE.
All I get is unable to connect the BE message. Form continues to open.
Thanks for insight.

Hey everyone I'm new here but pretty familiar with Access etc. I am extrememl;y stumped on this and I have never attempted this so any answers and details would be helpful. As we all know this is a learn new things as you develop type of application or at least for me.
I have a database that exists in one building and is functionnig fine using linked tables (File/Get External Data/Link Tables) but I now need to make this same application work for multiple locations which each have its own tables that are seperate from each other location. I was thinking a Main form that opens with radio buttons and based on the one you select would determine which tables it would be linked to when it opens. I figured Radio1 be SEDC, Radio2 be SWDC.
I have a database I have setup as a storage database for just the tables for each location that are on different servers in each location to increase traffic speeds.
Example:
SEDC (RadioButton1)
SEDC Database is located on a erver with 50 different tables in it "//sedc1/data/shared/warehouse/SEDC Warehouse.mdb"
SWDC (RadioButton2)
SWDC Database is located on server with same tables in it but different data for that location "//swdc1/data/shared/warehouse/SWDC Warehouse.mdb"
So on So on...

Hi,
I'm trying to delete a table once I've used it and always get the same error saying that the table is already in use, these are the commands I've tried:
DB.TableDefs.Delete ("Report")
AND
strSQL = "DROP TABLE Report"
DB.Execute (strSQL)
Can't figure out how to avoid this. Please help

I've been using the following code successfully in Access 2003 & now I need to migrate to Access 2010. The purpose of the code is to use the items that the user selects in the list box to build the criteria of a query. Access 2010 keeps giving me a syntax error when I try to run the query & I don't know why:
My code is:
On Error GoTo Err_Command151_Click
' Declare variables
Dim db As DAO.Database
Dim qdf As DAO.QueryDef
Dim varItem As Variant
Dim strCriteria As String
Dim strSQL As String
[Code] .....
The syntax error I get in Access 2010 is:
Syntax Error in query expression 'SELECT * FROM
qryContractListSummarybyDateContract3TYPEBREAK WHERE
qryContractListSummarybyDateContract3TYPEBREAK.Rep ortableName IN('Adbri
Masonry NSW');'

hi,
On the OnLoad event of a form, is it possible for the program to traverse or go through every single record (maybe with a while loop)?? If so, please send me the exact syntax.
Also, I want to update the tables on the back end. Is it possible to this in the be file? Where specifically would I have to put the code?
thanks

I am close to finishing a new database. In this database I have some VBA code that does a bunch of stuff, one of those things is to check if a temp table exists, and if yes then it will delete it.
Once finished this database will be made available to a range of people via Access Runtime 2010. I'm just wondering will the VBA code that deletes a table work in a Runtime environment?
I guess I should also ask if a save import process will also run via Runtime.just need to make sure that the users that need to do this code have full access if its required.

I searched and couldn't find anything on this specific issue.
I'm on the verge of designing a pretty big database and I've run into what may become a bit of a problem. There will probably be several backends in different locations. Should another backend ever be created or if the location for one changes, the user can use a form to refresh the links to the tables on that specific database.
The way I've done this so far is by having a piece of code that checks the tables for a connection string. If the table has a connection string, its a linked table, so the link gets deleted and replaced with the new link. Well this will no long work since there will be several backends and only 1 of them may need its tables relinked and using that code will delete all the table links, including the good ones.
Is there a way to make 'DoCmd.TransferDatabase' overwrite table names instead of giving the duplicate tables a number suffix? I think that doing this would be easier than retrieving the table names from the new backend and comparing them with the linked table names in the frontend so the old links could then be deleted.

I found 2 examples of code to refresh my attached table link to sharepoint lists.
I have a scheduled task open my Access 2010 db and an autoexec macro runs and closes the db.
My problem is my tables disconnect from sharepoint 2010 and the update fails.
I added the code I found to a module and added a line in my macro to run the code. Now I cannot get the code to work.
Am I at least on the right track? I just want to know before I spend many hours getting this code to work.
These are the two locations of code I found.
[URL]
I think part of my problem is that I have a regular table that I add a txt file to that is not linked to sharepoint so I need to exclude it from the code.

We have an Access 2000 backend database resides in a network server drive while users connect to the backend tables with a mde file on their computers. All users have Access 2010 and the mde file was converted from the 2000 frontend with Access 2010.
The database have been running for a few weeks but recently users have been complaining about record lost on the backend table.We have also experienced one incident of data corruption where the main table could not be opened. After Compact & Repair, the table could be opened but a few records were showing xxxxx on all the fields and we have to delete and re-enter these records.Would they relate to using 2010 mde converted from 2000 frontend when the backend is still in 2000? I am a little nervous about converting both the frontend and backend to 2010 since I have heard various issues on the new version.

I have two tables in my Access database. Table 1 has three columns, First Name, Last Name and Phone Number. Table 2 has just 2 columns, First Name and Last Name. What I would like to do is write a VBA macro to consolidate Table 2 into Table 1 and insure any duplicate First Name-Last Name combination is removed.
Table1
Code:
F.Name L.Name Tel.N.
John Smith 12345
Larry Miller 12344
Tony Woods 12333
Table2
Code:
F.Name L.Name
Albert Black
Larry Miller
John Bush
Table1 Post-Macro
Code:
F.Name L.Name Tel.N.
John Smith 12345
Larry Miller 12344

I've got 2 sub forms that I intend on using via a toggle button from my primary form to access them. Is there anyone that can give me a heads up on creating vb code that when OnOpen it will automatically advance to a new record for data entry? I want the form to keep anyone from accidentally changing existing info in that regard. I'm still really new with VB.
Thanks for any help,

I dont get any errors with this code. Let me explain what im doing:
T1 = temparary table (not really temparary but the values just change so often it might as well be)
this table has field names: partname, order, maxorder, etc. stuff like that
pretty much its a table that has records for each part name.
T2 = main database
this table holds the order for all parts for a particular time and day
T1 is the one that people are familiar with, where as T2 's set up is something that they would not be, so for clarity we use T1 for displaying etc.
now my problem is, i try to transfer data from one table to another but it works sometimes and doesnt work others, i dont get any errors and i have option explicit on as well. if someone could look at this code and tell me if there are any problems that you see, the quicker the response the better.
technical specs:
Access 2000
Windows 2000
Code:
Private Sub insertRecMainDB(ByVal typeOfOrder As String)
'This sub will insert a new record of type O (Ordered) and put in all values from the table Order
'Also it will make a duplicate record of type R (Received) and put in same values so when later
'if there are no changes (meaning all product was received) no entry has to occur, however if you
'are missing a part then you can enter how many on the other form.
Dim yesOrNo As String
Dim tempSQL As String
Dim rec As New ADODB.Recordset
Dim orderAmountRec As New ADODB.Recordset
Dim partNameRec As New ADODB.Recordset
Dim numOfRecords As Integer
Dim cnt As Integer
'Checks the type of order and either checks or does not check it in the DB
If typeOfOrder = "O" Then
yesOrNo = "yes"
Else
yesOrNo = "no"
End If
'Create the SQL statements to update MainDB
tempSQL = "INSERT INTO [MainDB] ([OrderNumber],[DateTime],[OrderedReceived],[TypeOfOrder]) VALUES (" + CStr(txtOrderNumber.Value) + ",'" + CStr(lblDateTime.Caption) + "'," + yesOrNo + ",'" + typeOfOrder + "')"
CurrentDb.Execute (tempSQL)
'Counts the number of parts we have to order, saves it in numOfRecords
rec.Open ("SELECT* FROM [Order]"), conn, adOpenStatic, adLockReadOnly
numOfRecords = rec.RecordCount
rec.Close
'Loop to transfer data from the table Order to the table MainDB
For cnt = 1 To numOfRecords
'Gets the name of each part
tempSQL = "SELECT [Description] FROM [Order] WHERE [PartNumber]=" + CStr(cnt) + ";"
partNameRec.Open (tempSQL), conn, adOpenStatic, adLockReadOnly
'Gets the amount ordered of that part
tempSQL = "SELECT [MaterialOrdered] FROM [Order] WHERE [PartNumber]=" + CStr(cnt) + ";"
orderAmountRec.Open (tempSQL), conn, adOpenStatic, adLockReadOnly
'Updates that part name with the ordered amount
tempSQL = "UPDATE [MainDB] SET [" + CStr(partNameRec.Fields(0)) + "]=" + CStr(orderAmountRec.Fields(0)) + " WHERE [OrderNumber]=" + CStr(txtOrderNumber.Value) + " AND [DateTime]='" + CStr(lblDateTime.Caption) + "' AND [TypeOfOrder]='" + typeOfOrder + "';"
CurrentDb.Execute (tempSQL)
partNameRec.Close
orderAmountRec.Close

Hi,
I have a form in access database. On click of a button I want to perform update process for records in a table "abc" in the same database. I have written the following code in the onclick function,
Code: Dim rs As New ADODB.Recordset Dim rsCount As New ADODB.Recordset Dim CntVal As Integer Dim con As New ADODB.Connection con.Provider = "microsoft.jet.oledb.4.0" con.Mode = adModeShareExclusive con.Open ("C: est.mdb") rs.Open "Select * from abc" Do While Not rs.EOF rsCount.Open "select count(test) from abc where test = '" & rs.Fields("test") & "'" If Not rsCount.EOF Then CntVal = rsCount.Fields(0).Value Else CntVal = 0 End If rsCount.Close con.Execute "Update abc set testcount = '" & CntVal & "' where ID1 = '" & rs.Fields("ID1").value & "'" Loop
In the above code, I am not able to use the command,
con.Open (App.Path & " est.mdb"). It gives "Object Required Error". And while opening the con object I get the error "You attempted to open a database that is already opened exclusively by user 'Admin' on machine ''. Try again when the database is available."
Kindly advise how to solve this problem.

I have a form that is created in Access but uses some VB code. Here is my problem..... I have one form that the users do money transactions on. Then I have created a form that will allow them to Void a transaction as well as Refund a transaction. On the Void/Refund forms it will query the user for the Receipt No. once that information is pulled in, there is a command button that says "Void Ticket Sale" on the Refund form it says "Refund Ticket Sale". What I'm trying to do is, once the user enters the receipt no and hit that Void/Refund Ticket Sale button - if it has already been voided/refunded, a message box will come up and say "This Ticket has already been voided/refunded". If it has not, the "Void Ticket Sale" command will carry on. Here is a snippet of my code, I'm not sure what I'm doing wrong.
Private Sub cmdRefund_Click()
On Error GoTo Err_cmdRefund_Click
'this is a AddRec button, caption was changed to read Void
Dim Answer As Integer
Dim Result
Dim sqlstmt As String
sqlstmt = "Select Count( * ) from tbl_transactions where PaymentType = Void And VoidRefundID = Me.TransNumID"
Answer = sqlstmt
If Answer > 0 Then
MsgBox "This Receipt No. has already been voided."
Exit Sub
Else
Result = MsgBox("Are you sure you want to Refund Receipt No " + Str$(Me.TransNumID) + "?", vbYesNo, "Refund Receipt")
If Result = VbMsgBoxResult.vbNo Then
DoCmd.Close
Exit Sub
End If
End If
