To Code Or Not To Code.
Mar 21, 2007
In the database I am creating a table that houses “subjects’ names” and their “unique IDs”, which are both indexed with no duplicates. The Unique ID is used as a FK to connect all the tables that contain information from the subject. When subjects are enrolled in one of our studies they are assigned a “Unique ID”, which is assigned sequentially. The IDs are alphanumeric, and consists of 4 characters with the first character being a letter:
A001, A002…A999, B001, B002…C001 etc.:
To help avoid data entry errors, I would like to automate the process of assigning these Unique IDs as much as possible. So my question is:
Is it better to manually insert all the possible Unique IDs into this table upfront and then use a code that allows the user to assign the next Unique ID to the subjects they are enrolling (ie search the subject names column for the first null field and enter value there)? Or would it be better to set up a code that looks through the IDs that are already in the list and then automatically generates and assigns the next sequential ID to the person they have entered.
Also, where might I find some pre-established code to get me heading in the right direction?
Thanks in advance!:D :confused: :confused:

Works great, but when I hit the number "3", (3 times in row) it will let me into the form. I want it to not let me in IF I don't know the password.
Where did I go wrong?
Private Sub Form_Load()
Dim pw As Variant
If InputBox("What is the password?", "Password") = "1" Then
Else
MsgBox "Invalid Password", vbCritical, "Sorry Charlie"
DoCmd.Close
If InputBox("What is the password?", "Password") = "2" Then
Else
MsgBox "Invalid Password", vbCritical, "Sorry Charlie"
DoCmd.Close
End If
End If
End Sub

I protect my code from people being able to read it by setting a password on the code from Tools > Properties, selecting the Protection tab and entering a password, and clicking "Lock Project"
Is there a way to write code that will remove that Lock Project check and check it back on?
I've looked through the Application.SetOption command and it doesn't seem to be one of the choices. It would be very helpful if someone knew how to do this.
Thanks

I have a button that runs a macro to insert NOW() into a text box.
This is how it is coded;
Private Sub Start_transferred_job_button_Click()
On Error GoTo Err_Start_transferred_job_button_Click
Dim stDocName As String
stDocName = "Start transfered job"
DoCmd.RunMacro stDocName
Exit_Start_transferred_job_button_Click:
Exit Sub
Err_Start_transferred_job_button_Click:
MsgBox Err.Description
Resume Exit_Start_transferred_job_button_Click
End Sub
How do I write the code to populate the [start Time] text box with NOW() when the button is clicked without using a macro???

Need a little help here. I have this code on a command button that open a form that displays a chart. The chart work great as long as there is data to display. However, if there is no data then the chart is blank. So what I'm trying to do is add a dcount to catch the 0 and give an error. So the 1st query makes the table where the data for the chart come from. The Qry-Test for Zero query, queries that new table if dcount is 0 it should error.
My problem is that I can't get this to work with the 0 if I make it 1 then I will get the message box if there are no records and if there is 1 record 2 and greater work fine. So my question is why won't the code catch the 0?
Dim stDocName As String
stDocName = "Qry-Makes Table"
DoCmd.OpenQuery stDocName, acNormal ', acEdit
If DCount(" * ", "Qry-Test for Zero") = 0 Then
MsgBox " There is no data for this time frame to chart. Please re-enter your Date range"
Exit Sub
Else
Thanks

Can anyone help with this code please. I keep getting Error 13, type mismatch on the on click event of a Command button.
Private Sub Command6_Click ()
Dim tmpFilePath AS String
tmpFilePath = Me!Text1
DoCmd.DeleteObject acTable, "Expire"
DoCmd. TransferDatabase_ acImport,"MicrosoftAccess",acTable,"tmpFilePath","Expire","Expire",False
End Sub
What I am trying to do is delete a table and replace it with a table of the same name in another db. the path to the file is stored in Text1. The delete part works OK then the error message arrives, when I run it with a static file path it worked ok, but I want to pick up the path stored in Text1 on my form.:confused:

In the code below, I am trying to autofill a field called WOSD (Work Order Start Date). It works for the Door Types or just the -4 option.
However, if the SpecialColor checkbox is checked, it needs to subtract 6 days from the LotDelDate. I must have something typed wrong.
I have been trying to get it to skip weekends as well with no luck.
Can anyone give me a hand?
Private Sub LotDelDate_AfterUpdate()
If Me.DoorStyle = "Eagle" Then
Me.WOSD = Me.LotDelDate - 5
Else
If Me.DoorStyle = "RP-9" Then
Me.WOSD = Me.LotDelDate - 5
Else
If Me.DoorStyle = "H/E" Then
Me.WOSD = Me.LotDelDate - 5
Else
If Me.DoorStyle = "F/E" Then
Me.WOSD = Me.LotDelDate - 5
Else
If Me.DoorStyle = "RP-9" Then
Me.WOSD = Me.LotDelDate - 5
Else
If Me.DoorStyle = "RP-22" Then
Me.WOSD = Me.LotDelDate - 5
Else
If Me.DoorStyle = "RP-23" Then
Me.WOSD = Me.LotDelDate - 5
Else
If Forms!FRMDELIVERY.Form.SpecialColor = "YES" Then
Me.WOSD = Me.LotDelDate - 6
Else
Me.WOSD = Me.LotDelDate - 4

Hi, I'm analyzing a program made with MS Access. It has a whole bunch of tables and queries already made, and a form with lots of code behind it. I'm looking through and I'm not sure what the following means:
With CurrentDb
.QueryDefs("qry_cur_pier").SQL = _
" SELECT DISTINCT RE.AIRPORT_RESOURCE_NAME,
RE.AIRPORT_RESOURCE_KEY " & _
" FROM qry_cur_resource AS RE " & _
" WHERE RE.AIRPORT_RESOURCE_CODE = 'PIER';"
qry_cur_pier appears to be an already existing query. AIRPORT_RESOURCE_NAME and AIRPORT_RESOURCE_KEY are fields in that query. AIRPORT_RESOURCE_CODE is not in the query though. What does the RE. and the AS RE do here? Thanks in advance.

Hello,
Is there a way of changing VB code so that ONLYif a statement is true then the command runs.
This is what I currently have:
If Me.chkDoorChoice = True And Me.cboFrontDoorType = "N/A" Or Me.cboFrontDoorColour = "N/A" Or Me.cboRearDoorType = "N/A" Or Me.cboRearDoorColour = "N/A" Or Me.cboAdditionalDoorType = "N/A" Or Me.cboAdditionalDoorColour = "N/A" Then
DoCmd.RunMacro "mcrPleaseNote"
End If
So the command should only run when chkDoorChoice is true. There are occasions when cbofrontdoortype = "N/A" and chkDoorChoice = False and the macro still runs. I dont want this to happen.
Any ideas peeps?

For example:
- the first request for the day would be "KEZ6313001AA" ...the 2nd would be "KEZ6313002AA" ...the 3rd "KEZ6313003AA"
- for the next day, it would be "KEZ6314001AA" ..."KEZ6314002AA" ...& so forth
- now the 'KEZ' is a constant string so it would always begin with "KEZ"; however, the rest is more complicated to concatenate.
- the next 3 numbers consist of the '6' from 2006 and the '313' is for the n-th day out of 365.
- the final alphanumeric number '001AA', '002AA' are the sequence numbers ('AA' will also stay the same); this number will reset to '001' each day.
I greatly would appreciate any assistance anyone could offer. Thank you!!!

I hope this is relatively simple. I have a command button that closes out a form, but was wondering if I could also write some simple code into the button to essentially "Alt-tab" out of access completely while the form closes. I'm still not very good in Access so any help is appreciated.
