Modules & VBA :: DLookup With Multiple Values - Loop To Check Entire Table
Jul 14, 2015
I have run into an issue with a basic DLookup. The database has grown in size and now we could have multiple entries, but I want it to return a certain one. So the information could be in it three times. Of course DLookup stops after the first one. How do I get it to loop to check the entire table? Someone mentioned to me to use a recordset, but how to write that as I have never used it before. Below is what I was using until this new request came up.
<code>
Private Sub txtloan1_AfterUpdate()
If IsNull(DLookup("[loan1]", _
"settlement", _
"[loan1]=""" & Me.txtloan1.Text & """ AND [status] = 'Open'")) = False Then
Cancel = True
MsgBox "Test", vbOKOnly, "Warning"
End If
End Sub
</code>
This was also executing after the user entered the information within a text field. I did not want them to enter all the data and then have it come back as a duplicate.

Basically, what's the best practice or how do we store a query's value into an array then checking what the max or min value is and how to check if let's say "4" is in the array?

I would like to make a DLookup that check 2 criteria in two different columns in the same table. The reason to use a DLookup is that I would like to check if two parts already have been linked together. The user therefore selects two values in to different comboboxes (lstLinkPart and lstLinkToPart). In this case the value of the first combobox is column: ComponentPN in tblProductLinkComponent. For the second (lstLinkToPart) column ProductPN, in the same table, has to be checked.
If both values from the comboboxes match the values in both (and only) columns I don't want to continue and made a code to be executed.
I found multiple examples on the internet for using multiple criteria but something similar to what I require.

I am making an asset table which amongst other fields have fields for "serialNo" and "Manufacturer"
I am trying to write some code that after update of manufacturer in the form, will check to see if that serialNo and Manufacturer exist.
ive managed to do it for one value, using
If Not IsNull(DLookup("[serialno]", "Assets", "[serialno] = '" & Me!serialno & "'")) Then
msgbox "blah blah"
which works great, but am struggling when i'm asking it to lookup two values.

I'm pretty familiar with getting values from a table via Dlookup. What I want to do is almost the reverse if possible? I'm declaring a variable as follows:
Dim Ref as string
Ref = [lead_id]
This is from a form.What I'd like to be able to do is go to the table [list], reference the lead ID in the table via the variable then change the field [status] to "INCALL".Can this be done in a similar way to Dlookup?
UPDATE - here is the code I am trying to use
Dim ref As String
ref = [lead_id]
Dim MySQL As String
MySQL = "UPDATE vicidial_list SET"
MySQL = MySQL & "vicidial_list.status = 'INCALL' "
MySQL = MySQL & "WHERE (((vicidial_list.status)= Ref))"
DoCmd.RunSQL MySQL
Which gives me an update clause error

I'm trying to write some Code with the target to take a value from a textbox (out of a form) and a pregiven value (in this case = 2) and enter them in a new record in a table. But only if there is not already a record with the exact same combination of these to values. When done, the same button should proceed you to the next form (but this code is not already implemented in the fragment below) even if no values are added because they already exist in this combination.
Code:
Public Function GetID_PatientStudiesGroup&()
GetID_PatientStudiesGroup = [Forms]![frm_PatientStudiesGroupTZP]![ID_PatientStudiesGroup]
End Function
Private Sub BPRS_T1_Button_Click()
Call GetID_PatientStudiesGroup&
Dim strSQL As String
[Code] ....
As you can see, I tried to use a function to refer to the value out of the form, because I didn't find out how to refer to a form in an SQL Code.
Just to give you a better overview: The table where the information should be added is named "tbl_PatientStudiesGroupTZP". The form where you find the Textbox "ID_PatientStudiesGroup" (with the value I need to transport) is named "frm_PatientStudiesGroupTZP". Every part (except the WHERE NOT EXISTS part) worked perfectly for itself, but not when thrown together.

I'm trying to find a code that will allow me to check a value of a yes/no checkbox based on a username.
What I want to happpen is:
1. The code looks to see if the username that is entered in "txtUsername" field on the form matches the "empUsername" value on the table "tblUsers."
2. If there is a match, I want it to look at the value for the field "Admin" on "tblUsers" to see if the value is checked as true.
3. If the value is true, I want it to open a specific form "frmAdmin." If it is false, I want it to open a form "frmMain."
VBA codes not recognizing the Admin field and instead taking all users into the frmMain.

I am a relative newbie to VBA, and not very familiar with loops, but I need to add a loop to my function that exports a query with criteria contained in a bound ComboBox on a form. I've gotten my code to work fine without the loop, but I would like to export one file for each item "Team_ID" contained in the ComboBox without the user having to manually select and re-run the function each time. Here is what my code currently looks like:
Code:
Option Compare Database
Option Explicit
Public Function CreateQCChartsforReports() As Boolean
Dim qdf As DAO.QueryDef
Dim strSQLStatic As String
Dim BookName As String
Dim BookName2 As String
Dim intCounter As Integer
Dim cboCode As ComboBox
[code]....

I made a custom function to look certain value from table based on couple of criteria that it gets from query where I want to use it. Function's code is below:
Code:
Public Function PotteryWeights(strLocusID As Long, nrPotSubID As Long) As Variant
Dim priSubID As Long
Dim priLocusID As Long
Dim priResult As Variant
priSubID = nrPotSubID
[Code] ...
However, when I use it in query it only returns Case else - option and everything else is empty.

I have a bit of code that uses controls on a form to batch add records to the tables. Before the code executes, it needs to do a check to make sure that all of the needed data has been supplied.
Code:
If IsNull(txtDateAdded) Then
MsgBox "Please supply the date that the Label record was created"
Exit Sub
Else
If IsNull(cboRecordCreator) Then

here goes with what I would like to add
job cancelled1 check box name field name= job cancelled
job on hold1 check box name field name = job on hold
void property1 check box name field name = void property
E.g. if I put date range in my date boxes and tick job cancelled show all record in that date range cancelled same with job on hold and void property
here some code I did but wont work as it not in the same strwhere above
Code:
if me[job cancelled1] = true then
strwhere = [job cancelled] = 1 'field name
else
strwhere [job cancelled] is null
end if
Some how need to add the strwhere to the code above ...

I have been trying to find a solution to why I can't get a Dlookup with multiple criteria to return the value I need.
Essentially I am trying to use an Order Number to find the item number which is contained within another table. However the order number has multiple lines (suffixes) which alter the item number. Therefore I am trying to have the item number be populated by the correct 'combination' of Order Number and line ("suffix").
I have managed to use the Dlookup in the after update of each box of the form separately and they retrieve values in the table correctly:
Afterupdate of main order number:
Code:
Private Sub OrderNumbertxt_AfterUpdate()
ItemNumbertxt = DLookup("item", "dbo_job", "[job] = '" & Forms![**INPUT]![OrderNumbertxt] & "'")
End Sub
Afterupdate of suffix:
Code:
Private Sub SuffixTxt_AfterUpdate()
ItemNumbertxt = DLookup("item", "dbo_job", "[suffix] = Forms![**INPUT]![SuffixTxt]")
End Sub
However when I combine them as follows in the afterupdate of the Suffix box I receive a "Run-time error '13': Type mismatch"
Code:
Private Sub SuffixTxt_AfterUpdate()
ItemNumbertxt = DLookup("item", "dbo_job", ("[suffix] = Forms![**INPUT]![SuffixTxt]") And ("[job] = '" & Forms![**INPUT]![OrderNumbertxt] & "'"))
End Sub
I think the reason is something to do with some being numbers and some being a combination of text and numbers (based on the replies of other topics), but have been trying to modify these slightly and can't get it to work still.
Also the Order Number is a combination of letters and numbers (normally in the form of AB12345678), the suffix is just a number between 0-9 and the Item number it finds is a combination of numbers and letters.

I am trying to loop through a table and count the duplicate records only once. Please see the attached file.
1) In the test table, I want to loop through all pt_accts.
2) In the countable column, if an acct repeats, I essentially just want to put "1" in one of the records. For the non-repeating accts, putting in a 1 is sufficient. Basically, I just don't want to count the duplicate ones multiple times.
In the example, acct "aaa" repeats, but there is just one "1" in the countable column. "eee" repeats as well, but there is just one "1" and the rest is 0.
Is this possible via VBA?

I have this
Code:
If Not IsNull(strCount = DLookup("[Number_Of_Records]", "All_Booked_Callbacks ", "[CallBack_Date] =#" & Me.CB_DAte.Value & "#" _
& " And [CallBack_Time] = #" & Me.CB_Time.Value & "#")) Then strCount = DLookup("[Number_Of_Records]", "All_Booked_Callbacks ", "[CallBack_Date] =#" & Me.CB_DAte.Value & "#" _
& " And [CallBack_Time] = #" & Me.CB_Time.Value & "#") Else strCount = "0"
All_Booked_Callbacks is a query which has a date and time columns and count of callbacks for that day and time, this always returns 0

I have the following VBA code that auto populates a word template:
Private Sub Command24_Click()
On Error GoTo ErrorHandler:
ErrorHandler:
[Code].....
The code executes flawlessy but there are three values that are based off check boxes set as YES/NO (EMPLOYEDATREGISTRATION, EMPLOYED and FRINGEBENEFITS). These values show up as -1 for YES and 0 for NO.
Is there anyway to add code to mine that would allow me to change these values before they are sent to the Word template?

I've set a database which has a table in which there are 2 fields "Account" and "Total Accounts". I want to have the amount of total summation of accounts in "Total Accounts" field of each record, which is the result of summation of "Account" values in all previous records till the current one. In order to do this purpose, I copied the value of "Amount" field of each record into "Total Accounts" field of the same record, at first. Then, I tried to add the amount of "Total Accounts" field of every record with just the amount of "Total Accounts" of previous one to earn the actual total amount of that record. I found that I need a VBA loop to do this query for all records (except first record) and so I code it as below, but it has the Run-time error '424' : Object required and it seems that I am in a mistake in definition of strSQL variable:
Code:
Private Sub doDataSegm_Click()
Dim dbs As DAO.Database
Dim rs As DAO.Recordset
Dim strSQL As String
Set dbs = CurrentDb()
Set rs = dbs.OpenRecordset("Table1", dbOpenTable)

I am trying to export a table in access based on a unique field called Group_Name. Say my table has 100 records. 10 of those records belong to Group1, 10 belong to Group 2, and so on. What I want to do is export those groups individually to an excel file and have that file named somting like Group1_Premium Detail Report.
Here is the Code I have so far. I have a feeling I am close. When I run the code it does not seem to like strrsql2
Dim strsql As String
Dim strsql2 As String
Dim strfilename As String
Dim strpath As String
strpath = "C:UsersDesktopHome"

I have an MS Access 2010 db that has a main form called switchboard. This has 4 command buttons that open diffrent forms. Also on the main switchboard form i have an unbound textbox called TxtUserName that captures the users environ"username" when the switchboard form is opened.
I have a table called "tblAccessUsers" that i manually enter who i want to use my db. This table will have up to 50 names added to it. Their is only one field name in this table and it is "User Login".
When the user hits any of the commandbuttons on the main switchboard form i need some code that will look at the value in TxtUserName and loop through tblAccessUsers for an exact match. If it finds a match then it will carry out the open form command or if not prompt the user with a message box.
My knowledge of Access and especially VB is quite limited. I managed to create this using a DLookup but that only returns the first record in the table. The logic works but it will not look past the first record.

I have a VBA routine that runs some queries and then creates a report as a PDF document using my virtual PDF printer. At this point it brings up the Save As dialog and I give the file a name and select a folder to store it in.
But I run this report 30 times for 30 different parameters. The parameters are obtained from a table which contains values such as Cancer, Diabetes, Stroke
-I always name the PDF file according to this value.
-I always choose the same folder.
-I always overwrite the reports I produced last month (copies have been sent elsewhere by then).
how can I get VBA to cycle through this code 30 times, each time selecting the next value from my table and creating/overwriting those files without the need for me to tell it the filename and path?
Code:
Private Sub lstSpecialties_DblClick(Cancel As Integer)
At the moment I am running this code by double-clicking an entry in the Specialty listbox, 'but I would prefer the whole thing to run multiple times for as many Specialties as exist in the table '(currently 30 but could be more in time)
'Warnings off
DoCmd.SetWarnings False
'Make the tables needed for the cumulative queries
DoCmd.OpenQuery "Spec 002 Monthly recruits - part 2 - make table" Each of these queries
DoCmd.OpenQuery "Spec 005 Monthly recruits - part 2 - make table" uses the Specialty selected above
DoCmd.OpenQuery "Spec 022 ABF previous year - part 2 - make table" as a parameter to get
DoCmd.OpenQuery "Spec 025 ABF current year - part 2 - make table" the right data for the report
[code]....
