Modules & VBA :: Link To Hidden Back End
Apr 1, 2014
I have a question that involves windows permissions as well as access links. I have a contacts database split into a front end and a back end. For security reasons I want to place the back end in a folder that is hidden from the users. In other words the users can access the front end as normal and run queries and reports but they are not able to navigate in Windows to the folder containing the back end or view its contents.
Is it necessary to use VBA to do this? If so what is the script? If not, how is it done.

I have a question about the best way to go about linking an excel workbook to an ms access table? I have researched hyperlinks and attachments and ole objects and I am not sure what is the best option. I believe hyperlinks will be best, because the attachments will bloat the database, but I am not sure how to go about doing that in vba? My process is such:
1)Users enter project information
2)Users enter the sample information for each project
3)The project and sample information is combined by a query
4)The user clicks a button to print forms, which runs the query and opens an excel workbook template.
5)The data is exported to a specific sheet in the workbook
6)Using vba in excel, the data is used to populate cells in different sheets depending on critera.
After all of this is accomplished, I need the user to SAVE AS the excel workbook and it needs to be "attached" to the ms access 'project' table. I am not sure what is the best way to link this back to the database. I would like to automate it with vba if possible.

using Access 2010, I have reached the 2GB limit. It's not the data, it's the PDF files I scanned in for each customer that has stretched the db to its limits. The db is also currently split.
I didn't realize Office had a 2GB limit; I assumed if you had a 64 bit computer and a NTFS partition, there would be no 2GB limit.
Using a template database in Access 2010, I need to extract the attachments to a folder and thus link them back to the database using hyperlinks. I can handle this task, but I'm not confident how to extract the attachments from each record (around 900) to a folder and have it do it automatically for all records. I can do it record by record, but that is not feasible with this many records.
how to extract all the attachments for each record, and have them saved in folders by their name or other ID, so I can link them back to the db via a hyperlink?

I'm trying to add hidden information to a record and need to know the best way to do it.
I have a visible table that all users enter data into using a form.
I also have a hidden table that contains 2 fields "linked Table ID" and "notes"
I have a box at the top right of my form which is white (I also have a white background so it's impossible to see).
When you click the box it changes a textbox on my form visible property from false to true.
then I plan to use a separate button that the user currently uses to save a record to store ID number and hidden textbox information in the hidden table but I'm sure how to do this.
Finally I will use a hidden query which will display all the fields from both tables using the linked Table ID from the hidden table and ID field from the non hidden table.
So i have 2 questions:
1 how do I save information the user entered into a form created from one table into a different (hidden) table
2. Is this the right approach to this problem?

I am designing a contact database for a diocese and the contacts record form is divided into several tabs, some of which are hidden by default. One of the controls on the form is a listbox (lboRoles), where a user can add one or more roles to contacts. The listbox has a hidden column that defines the TabIndex for the assigned role, and my goal is to make the associated tab on the form that was previously hidden, to now be visible.
For example, if a contact is assigned the role "Committee Member" and the tabindex value for that role is 3, the form should make the hidden tab (where the page index is also 3) now visible.

I am splitting a database and have created the Back end already. When I create the front end and link to the tables on the back end... The front end does not link to all the tables in the back end. The list that comes up when creating the linkings does not show all the tables in the back end. What would cause this?

I am trying to determine the best method for linking back to a form from Queries.I have a Form that has info filled out for customer service calls that come in. Among which is a case#. From the Log of information stored from these forms queries have been made to organize the info in different ways; all of which have the case#. What I am trying to do is that in looking at a the queries I want them to be able to click on a case number and be transferred to the appropriate form. This way they can update the form as the case progresses.I am trying to improve upon what was created by another.

Can I create a table in the back end of my database using VBA in the front end? My client is using this system and I can't easily go to their location. I need to create a table on the back end and have it available in the front end applications. My thought is to create a front end only for the purpose of updating the backend with this new table. My idea is now to have it open with a button for the user to click - this will add the table to the backend with the required fields, confirm the update was completed and then close. This app then would be trashed so it would not be run again. (Though I would put a check in the VBA that if the table existed, the user would get a message box and the coding stopped to avoid overwriting the existing file.)
And once the table is created, is there a way to programmatically link it to the front end. I will be providing a new front end with this update so I could add something in the new version.

I have an unbound textbox with certain value. I want the user to be able to change the value, but first, I want them to get a question about it. I have added the following code to the before update event for that textbox. If they answer "No" to the question i want the value to go back to what it was, but if they say "yes" then I want the value to stay and a table to be updated.
Code:
Private Sub txtCustRepID_BeforeUpdate(Cancel As Integer)
Dim CallIDVar As Long
Dim sName As String
Dim CustRepIDNew As String
Dim CustRepIDOr As String
CustRepIDOr = Me.txtCustRepID.Value
[CXode] ....
The code for "Yes" works well, but when the user selects "no", the value in the textbox does not reverse back to the original value.
What do I need to do?
Also, I would like to add a message box that says "The value has been changed from (original value) to (new value)" How do I do that?

I have a Back end (with password) which resides in a netdrive while the front end is installed in each individual users desktop, the problem is, some of the users netdrive was mapped in a different way (different letters..some are J others are G). I'm looking for code that I can relink the database to the front end in runtime, I did try to look in the net but I can't find anything that I can put the password as parameter.
this sample code from Dev is good, but i got an error because the database requires a password.where i can put the password?
Code:
Function fRefreshLinks(NewDbName As String) As Boolean
Dim strMsg As String, collTbls As Collection
Dim i As Integer, strDBPath As String, strTbl As String
Dim dbCurr As Database, dbLink As Database
Dim tdfLocal As TableDef
[code].....

I have the usual setup with a front and back end.
I want to copy three of my tables from the back end to another database (backup) at regular intervals. When using docmd.CopyObject and docmd.TransferDatabase it is the link that get copied (naturally) and not the table itself.

I've got a private sub that runs when the form loads. I want it to get the id of the record which has opened this new form.
The public sub populates the variable but it's Empty going back into my private sub. I'm sure its a simple school boy error but it has me stumped!
I want it public as I need to keep that id as new records are added in the form.
Private Sub Form_Load()
FRStudentFundingRequestID
'fundingrequest = FundinRequestID
Me.txtFKFReq = FundingRequest
End Sub
__________________________________
Public Sub FRStudentFundingRequestID()
FundingRequest = [Forms]![frmFundingRequest]![txtpk]

I have a function which exports some data to Excel, performs some work, and then attaches the final report to an e-mail. As a result of various temporary columns being added / removed (for formulas to determine scope etc.), the main sheet ends up scrolled to the bottom of the used range. Before I attach it to the e-mail, I want to scroll the sheet back to the top-left corner (A1).
Code:
Public appExcel As Object ' Excel Application object (late-bound)
Dim objWorksheet As Object ' Excel Worksheet object (late-bound)
objWorksheet.Activate
With appExcel
With .ActiveWindow
.ScrollRow = 1
.ScrollColumn = 1
End With
End With
It worked up until this week, when I had to make some changes to the rest of the code to refine the output. Now, when it hits the ".ScrollRow = 1" line, I get RTE 91..how I can get the sheet to scroll to the top-left before I save it? (Such that, when subsequently attached to the e-mail, the recipient will open the workbook at the top-left cell and not sacrolled to the bottom).

I have the following function that I found online. Unfortunately I can't remember where I got it since I've had it for a little while. Today, when I tried to actually put it to use it didn't work.
I'm calling it from a form as follows: CompactDB (tblHotword)
tblHotword is just a random table from the back end. My understanding of the function was that it would use that table to connect and get the file name of the back end.
Whenever I run it, Access pops up a window that says "Object required" and nothing else. It doesn't look like a standard error message popup. When I click 'OK', Access continues with the rest of the code as if nothing went wrong. The function doesn't run though.
Code:
Public Function CompactDB(TableName As String) As Boolean
On Error GoTo Err_CompactDB
Dim stFileName
DoCmd.Hourglass True
stFileName = db.TableDefs(TableName).Connect
[code]....

I have a listbox which is populated by a query from a table.
I also have a sub which allows users to quickly select multiple items from the listbox (based on a pre-defined criteria) rather than scrolling through and selecting them manually / individually
The sub works fine but when it is finished, the listbox is automatically scrolled to the bottom (or, rather, to the last selected item)
I would like to have the listbox scroll back to the very top once all of the appropriate items have been selected.
(I could loop through the listbox items in reverse - or 'bottom-up' - in the code but that would only have the desired effect if the topmost item was selected. I want it scrolled to the top regardless of whether the topmost item is selected or not).
