I'm currently using a piece of code to display who is logged into our Access Database. It's a split database, with a backend and multiple frontends. I am currently using this code:
Private Sub btnShowUsers_Click()
'The User List Schema information requires this magic number. For anyone
'who may be interested, this number is called a GUID or Globally Unique
'Identifier - sorry for digressing
Const conUsers = "{947bb102-5d43-11d1-bdbf-00c04fb92675}"
Dim cnn As ADODB.Connection, fld As ADODB.Field, strUser As String
Dim rst As ADODB.Recordset, intUser As Integer, varValue As Variant
Set cnn = CurrentProject.Connection
Set rst = cnn.OpenSchema(Schema:=adSchemaProviderSpecific, SchemaID:=conUsers)
'Set List Box Heading
strUser = "Computer;UserName;Connected?;Suspect?"
Debug.Print rst.GetString
With rst 'fills Recordset (rst) with User List data
Do Until .EOF
intUser = intUser + 1
For Each fld In .Fields
varValue = fld.Value
'Some of the return values are Null-Terminated Strings, if
'so strip them off
If InStr(varValue, vbNullChar) > 0 Then
varValue = Left(varValue, InStr(varValue, vbNullChar) - 1)
End If
strUser = strUser & ";" & varValue
Next
.MoveNext
Loop
End With
Me!txtTotalNumOfUsers = intUser 'Total # of Users
'Set up List Box Parameters
Me!lstUsers.ColumnCount = 4
Me!lstUsers.RowSourceType = "Value List"
Me!lstUsers.ColumnHeads = False
lstUsers.RowSource = strUser 'populate the List Box
'Routine cleanup chores
Set fld = Nothing
Set rst = Nothing
Set cnn = Nothing
End Sub
This works, and it returns the laptop numbers of the users currently using the system, but in the 'Username' column it just says 'ADMIN'. Is there any way to get this to show their Windows username, ie their VBA.Environ("USERNAME")?
No, this is not possible.
This column shows the Access username, same as the Application.CurrentUser() method.
Unless you set up user-level security, add all users to the workgroup file, and start Access with a command-line parameter like
/User %username%
, the user name will always be "Admin".

I have a table with a field containing multi-valuable as shown below:
In the form, I want to let the user enter a NCR_Num in the textbox then using VBA to do some input validation then add it to the "text_Pool" as shown below:
This Text_Pool has the NCR_Num as the control source so if there is a NCR number added or deleted from it, it will automatically update the NCR_Num field.
I am not quite sure how to handle this data type.
In VBA, I cannot obtain the value from the Text_Pool because I think I need to treat it as an array or recordset
Below is an example of me trying the recordset attempt but obviously I am quite confused on what I am doing:
Public Function get_NCR_Num(SCAR_Num As Integer) As Integer()
Dim dbsMain As DAO.Database
Dim rstMain As DAO.Recordset
Dim childRS As Recordset
Dim sSearchField, sCriteria As String
Set dbsMain = CurrentDb
Set rstMain = dbsMain.OpenRecordset("tbl_SCAR", dbOpenDynaset, dbReadOnly)
Set childRS = rstMain!NCR_Num.Value
sSearchField = "[SCAR_Num]"
sCriteria = sSearchField & " = " & [SCAR_Num]
With rstMain
.MoveLast
.FindFirst (sCriteria)
With childRS
Do While (Not .EOF)
MsgBox (childRS!NCR_Num.Value)
.MoveNext
Loop
End With
End With
rstMain.Close
dbsMain.Close
Set rstMain = Nothing
Set dbsMain = Nothing
End Function
Any help will be appreciated!
I misunderstood your question, and have updated the answer with the following code. This should do what you want. Replace the code you have in subroutine 'Command_LinkNCR_Click' with the following.
This will: (a) validate nbr exists; (b) add if not present; (c) remove if present;
WARNING!! This code only addresses the one issue you were trying to overcome. However, it makes an update of the same recordset as you are viewing on the form, so there may be an issue if your form is 'Dirty'.
Give this a try and let me know if you have questions.
Private Sub Command_LinkNCR_Click()
Dim dbs As DAO.Database
Dim rsMain As DAO.Recordset
Dim rsChild As DAO.Recordset
Dim strSQL As String
Dim blnMatch As Boolean
If IsNull(Me.Text_NCR) Or Me.Text_NCR = "" Then
MsgBox "No value entered for NCR_Num", vbOKOnly, "Missing Value"
Exit Sub
End If
blnMatch = False
Set dbs = CurrentDb
' Only need to work on the current record
strSQL = "select * from tbl_SCAR where SCAR_Num = " & Me!SCAR_Num & ";"
Set rsMain = dbs.OpenRecordset(strSQL, dbOpenDynaset)
If rsMain.EOF Then
' Should never happen
Else
Set rsChild = rsMain!NCR_Num.Value
If rsChild.EOF Then ' If no values yet, add this new one
MsgBox "Add item"
Else
Do While Not rsChild.EOF

I've got the attached query, which shows several rows (there is more data) but only 2 email address. I would like to send the corresponding rows to their relevant email address. All these details change every week, and there will be more (and sometimes less) email addresses, so I need to keep the data coming from this form (rather than static addresses). I've tried making a report, and can manage to send that to the email address, but I get multiple forms/emails for this report. The query will show a lot of records, so this is not an acceptable solution.
Any help would be gratefully received.
EDIT - I've attached the tables which show the data. I just want to send each company their own few rows by any means possible. Please help :)
Thanks.

and I've added into my "Onload" event on the Report:

You need to open a recordset in VBA that contains the unique email addresses.
Loop through the recordset, opening your report, filtering on the email address and emailing the report. Air code:
Dim rS as DAO.Recordset
Dim dbS as DAO.Database
Set dbS = CurrentDb()
Set rS = dbS.OpenRecordset("Select DISTINCT emailaddress FROM <yourquery>",DbOpenSnapshot)
Do While Not rS.EOF
<sometempvar> = rS!emailaddress
'your code to email filtered report using <sometempvar>'
rS.MoveNext
Loop
Set rS = Nothing
Set dbS = Nothing
You need to create a query to only return the emails and specify the query to return unique values only, there is an option for that in the query editor:
Access 2003 / SQL Server - how can I update Access 2003 MDB (Connect property) to point to a different SQL Server database? The new SQL Server database is on the same instance as the old one.
I have several MS Access 2003/SQL Server applications that I manage. All of them dynamically attach to the correct database at startup. Some of them even connect to multiple databases on different servers during the start up sequence. All of them use the same basic vba routine to actually dynamically attach a table to the correct server. This is not my code, I found it by googling around the internet, but I have lost the reference to it now, so apologies in advance to the authors.
Before showing the code, to put it in context, I normally have a form "frmInitApp" with a data source that is a local config table, with a field named "ID". I start the access application from the AutoExec macro which opens this form with a filter of "ID=1". I have other forms to manipulate this config table and change the IDs around, so to switch between production and test I just change which entry has ID=1.
I also have another local table, tableList, with a list of Access tables that I want to connect dynamically to a SQL Server. Most applications have another field in this table for the SQL Server table name (so they don't have to be the same) - some applications have an additional field to specify which database. But the more complex the more other spaghetti you need - I often end up with another table of connection strings to all the separate databases I might connect to etc etc. To keep it simple just have the connection string in a field in the config table that is the datasource to frmInitApp.
We get started with the current event on frmInitApp.
Private Sub Form_Current()
If Me.Filter = "" Then 'If nobody has told us what record to use then use id=1
Me.Filter = "[ID]=1"
configID = 1
Else
configID = CInt(Mid(Me.Filter, 6)) 'We are assuming the load criteria are "[ID]=..."
End If
Me.messages = "Connecting to databases ..."
DoCmd.Hourglass True
Me.stage = "InitialStartup" 'Set the stage which is to be executed during timer phase
Me.TimerInterval = 100 'We set the time to go off to so we can let autoexec finish and let us control focus
End Sub
and then in the timer we can link to the tables via an attach table function with I'll put further down the answer. Note also that we relink pass through queries as well so they point to the new database also. Also note that we start Open a new form a login one fore users as soon as we have attached to the first table. I don't show the conclusion where will probably have to validate username and password against the attached table when its all done, but its trivial to figure out anyway.

The database is supposed to pull in information from the Excel sheet that is passed through to it, and import the information into a recordset of the text field. However, the text field, somewhere down the line, has been limited to 50 characters. How can I change the maximum size of the text field? Thank you for any help

In Access, open tbl_recomendations in Design View. It sounds like the Field Size property for Idea_# is set at 50. You can change that up to 255.
If you need to store more than 255 characters in Idea_#, change its Data Type from Text to Memo.
I have put together a procedure to cycle through a table containing paths to text files and import them into the database.
Reason for procedure:
The reason for this is I am building a back end to many reporting databases that rely on nightly updated text files. Recently they changed the server name and file names for these files, so I'm trying to build something more reliable so I don't have to run through the link table wizard making sure all the data types are exactly the same as before.
Issue:
The issue I have is the With .edit .update isn't acting like I thought it should and updating the field 'Updated' in the table to today's date.
Here is the code. I'm still new to programming, so apologies.

Where you have

You meant

Mistakes such as this can be caught by turning on Option Explicit. Option Explicit means that all variables must be declared.
See here: How do I force VBA/Access to require variables to be defined?
