I created a Public Function called fNetWorkDays in my access database, however, when I try to use it in an expression I get "Undefined function 'fNetWorkDays' in expression". The Public Function is in a standard Module in my vba project. Why I cannot call it in my queries?
View RepliesHi all,
I'm trying to get a public function to work within the design view of a query. The function is defined as:
Public Function Percentile_(fldName As String, _
tblName As String, p As Double, _
Optional strWHERE As String = "") _
As Double... ( I can put the whole code if u need it)
Any thoughts about how I can make the Percentile function calculate values according to a GroupBy statement and not for whole data set?
Hi All
I have used Allen Browne's code (see http://allenbrowne.com/ser-16.html, bottom of page) as a model for my user-defined type and public function in an events management database.
Using the function in forms/VBA works fine.
But my DB crashes whenever I try to use it in a query.
My modules code:
= = =
Option Compare Database
Public Type EvCheks
EvType As String
EvAttCat As String
EvUnitAss As String
EvCheksAll As String
End Type
= =
Public Function getEvCheks(EV, EvUnit) as EvCheks
'Event Type: Event or DL
If (DLookup("evtype", "tblevents", "[evid] = " & EV)) = "Event" Then
getEvCheks.EvType = "Y"
Else: getEvCheks.EvType = "N"
End If
'Event Attendance Category: INDB= in database or LIST
If (DLookup("evattcat", "tblevents", "[evid] = " & EV)) = "INDB" Then
getEvCheks.EvAttCat = "Y"
Else: getEvCheks.EvAttCat = "N"
End If
'Event Assessing Organisation
Dim AOROName As String
Dim AOName As String
AOROName = DLookup("evunitassessable", "tblevunits", "[evunitid] = " & EvUnit)
AOName = Mid([AOROName], 1, InStr([AOROName], "/") - 1)
Select Case AOName
Case "NA"
getEvCheks.EvUnitAss = "N"
Case "ABCD"
getEvCheks.EvUnitAss = "Y"
Case Else
getEvCheks.EvUnitAss = "X"
End Select
getEvCheks.EvCheksAll = getEvCheks.EvType & getEvCheks.EvAttCat & getEvCheks.EvUnitAss
End Function
====
On a form, I have a button with on-click event code that defines the EV and EVU variables and displays a message box
MsgBox getEvCheks(EV, EVU).EvCheksAll
This works fine.
=====
In a query I have this SQL code:
SELECT tblEvUnits.EvId, tblEvUnits.EvUnitID, getevcheks([evid],[evunitid]) AS EventDetails
FROM tblEvUnits;
This causes the db to crash.
I cannot get the "back-end" definition of the function into the query, as Access rejects it because of the dot, i.e. ".EvCheksAll".
I suspect there is some formatting quirk for using a public function that includes a user-defined type, in a query.
Any/all assistance much appreciated.

I am using a public function to feed a variable string to a query. So far I have got:
Code:
Public Function ClientStreetModule(firstLVar As Variant, streetVar As Variant, newFL As Variant) As String
Dim cslStr1 As String, newStreet As String
newStreet = Right(streetVar, Len(streetVar) - Len(newFL))
[code]....
However, I only need to use newStreet as the true part of iif, in which instance all are longer. At least I think this is the problem. I realise I might need to use NZ but am not sure how. Why it is evaluating and giving errors for all records and not just when the iif criteria is true as I want it to?
Simply put, I have a front end that does a bunch of file moving and if it encounters an error and stops processing (which is intentional) I am the only that can login to the machine and fix it.
Is there any way to run it that would allow others to login on their own user profile, solution the problem, and start the processing again or am I stuck to a "per profile" instance?
I can't just let others login as me
I'm new to VB and am learing slowly with all your great help in this forum.
I'm wondering if its possible to write a Public Function for vbCRLF. I have a field in multiple forms that are all named 'Note'. If I have the following code:
Public Function PubNoteLF()
On Error GoTo PubNoteLF_Err
My!Note = My!Note & vbCrLf
PubNoteLF_Exit
Exit Function
PubNoteLF_Err
MsgBox Error$
Resume PubNoteLF_Exit
End Function
When I run the code I get Compile Error: 'Sub or function not defined.'
Can someone tell me what I'm doing wrong? Its problably something real basic, but I'm stumped. Thanks.
I haev a report with 15 sub reports. I have to use Visual Basic to format the sub reports. I know how to do the formatting (see below) but what I would like to do is have one function (Public) that I can pass the subReport name to and have the formatting happen. This would be mush easier to maintain than copying the code below into on_print events of all 15 sub reports.
Has anyone done this and have an example??
Thanks

I have a query that I'm working on through Access 2010's design view. I'd like to add a criteria to the query where it only shows results with the employee name column matching a global variable I created that stores the name of the currently logged in employee.
Here's my vba code that declares the global variable and the public function i'm trying to pass as criteria in the query:
Global gbl_loginName As String
Public Function returnName() As String
If IsNull(gbl_loginName) Then
returnName = "test" ' dummy account created for development only
Else
returnName = gbl_loginName
End If
End Function
and here's the SQL code from Access's design view:
SELECT [Entry of Hours].WC, [Entry of Hours].[Employee Name],
[Entry of Hours].[Set Up Time], [Entry of Hours].[Run time],
[Entry of Hours].[Traveler Number], [Entry of Hours].[Entry Date],
[Entry of Hours].[Quantity Finished], [Entry of Hours].Notes, [Entry of Hours].WPS,
[Code] ....
when I try running the query, however, I get this error:
'returnName' is not a recognized built-in function name
Is there a problem with using public functions in Access' design view?
I am trying to read the value of a control on an open form from a Public Function in a Module with no luck. I suspect the issue is syntax.
Code:
Public Function MyFunction(varFormName As String, varControlName As String)
If Forms(varFormName).Controls(varControlName) = True Then ' = 0 even when control is -1
Else
End If
End Function
The variables pass through fine but the If statement equals zero regardless of the state of the form's control. I tried several variations to no avail.
If Forms(varFormName).Form.Controls(varContactControl ) = True Then
If Forms(varFormName)!Form.Controls(varContactControl ) = True Then
Etc.
I have an issue with this case select below. The DelayStart is time so lets say I put in the debug window
?DatePart("h", #04:00pm#)
The result would be 16 which is correct BUT the issue is my second shift starts at 04:01pm and the result is still 16 untill 5pm. How do I fix this so I get the correct shifts? Im guesing use something other than DatePart but what?
'Daylight 6:00am - 4:00pm
'Afternoon 4:00pm - 2:00am
'Midnight 2:00am - 6:00am
Code:
Public Function getShiftForRecord(DelayStart As Variant)
On Error Resume Next
Select Case DatePart("h", DelayStart)
Case 6 To 16 'Daylight 6:00am - 4:00pm

I have built an access application that contains a set of buttons along the top of every form that serve as navigation.* These buttons each perform the same function on every form they are on. (menu opens the main menu, etc) I have database macros to assign each button the same function but I still have to go through each form and manually assign them. I was wondering if it was possible to define a public function that on db open will look for all buttons with a certain name and assign them the macro. (so all buttons called cmdmainmenu will have the OpenMainMenu macro assigned and so on).Before you go there, I have already tried the navigation form and set all forms as subforms.
View 5 Replies View RelatedQuestion for Documentation purpose: Should the Public Type be declared in its own module?
Or should it be declared in a standard module where non-public functions use it? It is not for a Form module use.
For a Rule Engine, a function is calling one record on 4 different SQL Views (as linked tables) that have the same field format.
For speed, the recordset should only be opened once. However, there are multiple values that must be returned to the result table multiple fields.
One way to return multiple values is an Array. That has over head too.
Another way is to create multiple public variables. Not my choice for documentation. Another is to create a string.
This is a pure code module with several non public functions / subs. What is the documentation preference? List a Public Type close to the function, or place it in the Global module?
Background: A function can only have one return value.
By creating a public Type, multiple values can be returned.
Code:
Public Type Income
Wages As Currency
Dividends As Currency
Other As Currency
Total As Currency
End Type
Use this structure as the return type for a function. In a real situation, the function would look up your database tables to get the values, but the return values would be assigned like this:
Code:
Function GetIncome() As Income
GetIncome.Wages = 950
GetIncome.Dividends = 570
GetIncome.Other = 52
GetIncome.Total = GetIncome.Wages + GetIncome.Dividends + GetIncome.Other
End Function
To use the function, you could type into the Immediate Window:
GetIncome().Wages
(Note: the use of "Public" in the Type declaration gives it sufficient scope.)
Important Notice The way this function is called will work, but is wrong from the aspect it re-calls the recordset over and over.
See the proper way to use it submitted below.
I am designing a Public Function F()
I want this function to populate value from a any field selected from any table to any text box in any form ...... Lets say in a Database named TestDB we have a Table named tblTest , a Form named frmTest and in this form( frmTest ) we have one Bound Combo Box named cmbTest and one unbound TextBox named txtTest
We assume that the table tblTest has three fields : TestID , FName and LName .
We also assume that there are already some records in the Table tblTest .
If the function F() is already programmed it should take as arguments as it follows :
F(FormName as??? ,ControlName as ???, TableName as ???, FieldName as ???, ID_Field_Name_of_the_Table as ???, Combo_box_selected_ID as ???)
In result the function should (probably) DLookup (FieldName , TableName , ID_Field_Name_of_the_Table = Combo_box_selected_ID ) and then store the value in a variable ( probably Variant ???) , lets say called varSetValue.
The problem is IF this is the correct way to handle that issue , than what should i do next.... I really don't know how to pass a Control's name to a function from the Event module of the ComboBox -
I mean - how can I obtain the value so it is usable for the function .... What data type should be the function arguments so I can use them to set a value for a control in any form .
In example : If the Dlookup() is somehow successfull then I want to assign the varSetValue to the txtTest what should I do : FormName.ControlName.Value = varSetValue >??????
I have read a lot materials but couldn't find a good answer for that , and aswell what data type should be the arguments that the function accepts and how do I obtain Controls and Forms names so I could use them in the function as described above .
I have created a Public Function that would get a new Production Instructions number based off the [PI Number] of Tbl_Production_Instruction table.
I have a form that people will put in all information but the PI Number, then when ready they will click a button to update the PI Number. I place an unbound txtbox that will be hidden, with the control source to =NewPINum(), but when I tested the see if the unbound txtbox was populated with the new PI Number it was blank.can't figure out what I am doing wrong.
Code:
Public Function NewPINum() As String
Dim vNum As String
Dim strYYMM As String
Dim getnextPI As String
strYYMM = Format(Date, "yy") & "-" & Format(Date, "mm") & "-"
If strYYMM = Left(DMax("[PI Number]", "Tbl_Production_Instruction"), 6) Then
vNum = Right(DMax("[PI Number]", "Tbl_Production_Instruction"), 3) vNum = vNum + 1 getnextPI = Format(Date, "yy") & "-" & Format(Date, "mm") & "-" & Format(vNum, "000")Else
vNum = "001" getnextPI = Format(Date, "yy") & "-" & Format(Date, "mm") & "-" & Format(vNum, "000")
End If
End Function
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 multiple reports that use similar IIF statements as the controlsource for four textboxes. Naturally, I don't want to have to update twelve controlsources if any of the calculations change, so I thought I'd make this a public function. However, I don't know how to pass along multiple textboxes as variables. Here's what I have so far:
Code:
Option Compare Database
Public Function txtColor(ByRef textbox As Control)
Dim str1, str2, str3, str4 As String
'The IIf statement is simplified for this example. It's not important.
str1 = "=IIf(IsNull([Inquiry start date]),'W',IIf([txtInquiry]<1 And IsNull([Inquiry end date]),'R'))"
[Code] ....
And this is in the report (where ??? is what I'm asking about)
Code:
Private Sub Report_Load()
Call txtColor(???)
End Sub
The error I get is "Runtime 424 Object Required"
I have a table with only two fields and one record: BegDate and EndDate (beginning and end date of the reporting period respectively). I also made a function with variables that look up those values for use as a date parameter in a query.

Option Explicit
Public Function getCurrentRepDates() As Date
Dim dtBegDate As Date
dtBegDate = DLookup("BegDate", "tblCurrentRepDates")

I am getting a syntax error for the line marked red. How can I use "Between" function in VBA code? Access 2010
I am working on recreating an excel file in access. My excel files uses the Vlook up function to get data from a table for calculations.I am calculating Fruit Solids.
=VLOOKUP(BRIXVALUE,'Brix Table'!$A$1:$F$752,6)*QUANTITY
(BRIX VALUE references a cell, and quantity references a cell just used the names instead of cell references).The Brix table has 751 entries. The headers for the following tables are "Brix, Gravity, Weight, GFL, LBS, FS/Gal".So the look up table takes the BRIX value, finds it in the first column then takes the value in the 6th column(FS/Gal) then multiples that by the Quantity inserted in the other table. I didnt create the Vlook up access form so I am trying to get an understanding and recreate it in access.
In access i made a table called BRIX to store the Brix table information like the one in excel.Then i have fields in a different table where you enter the quantity, and brix value of the product. I now need to make the Vlook Up function in excel work for my access data.
Which function in access return the the last value in a string.
Period 1 Period 2 Period 3
10 20 30
I need the function to return 30.The reason behind this I have different periods for categories and my formula I'm using needs the ending value.
I'm relavtively new to databases but after a steep learning curve (being left with many databases created by my old manager with no instructions on use) I'm getting there.What I am trying to do is pull out the date from records in a field called "Model_ID". The Model_ID field contains this kind of information:
Endscopy20120726JSmith
GISurgery20120521JDoe
I want to bring back "20120726" or "20120521". In excel I can do this with the mid and find functions but find doesn't work in access. I've tried combining the mid function with instr function but it comes back as too complex!
I have a query
Code:
Select distinct [tbl_DTP/CTP].id_zlecenia, [tbl_DTP/CTP].Folia_na_lakier_UV, [tbl_DTP/CTP].Wykrojnik, [tbl_DTP/CTP].Makieta, [tbl_DTP/CTP].Matryca_do_tloczenia, [tbl_DTP/CTP].Matryca_do_zlocenia, [tbl_DTP/CTP].kalka, tblGoraZleceniaRoboczeLaczenie.NumerZlecenia from [tbl_DTP/CTP] inner join tblGoraZleceniaRoboczeLaczenie on [tbl_DTP/CTP].id_zlecenia = tblGoraZleceniaRoboczeLaczenie.NumerZlecenia where tblGoraZleceniaRoboczeLaczenie.NumerZlecenia = r1;
Where "r1" is a public variable as string.The variable has value e.g. "10/145" But query can't get this value and all the time ask about value from "r1" :/
i'm trying to count the total number of records found for this query. i used the following expression (code) in the QED field row Total Incidents: Count([IncidentID]) which, result in an error message.
Can sum1 help me solve this problem. any help would be highly appreciated.
Hi,
I am on a elementary level of MS Access skill.
I am trying to create an expression, where I want to round up the value in a field.
Expr1: ROUNDUP([compass_pro_cost_data]![billed_weight],0)
When executing the qry, I get :
"Undefined function "ROUNDUP" in expression, I am using Access 2000. What am I doing wrong, or Is there another way ?
I started using Access recently and I have an inquiry about VBA codes and sql queries. I have function which has the following signature: RAG(Stability as Integer, DS_SYNC_RATE as Integer, Profile as String) as String.
I would like to call this function in Insert sql query in order to calculate and add a new column to my table. I tried this basic query:
Insert INTO my_table VALUES (RAG(my_table.stability,my_table.ds_sync_rate, my_table.profile))
but it doesn't seem to work...
Hi ALL,
I have 2 tables, trying to update one table filed by using max(onefiled) from other table.
my qyery is as follows:
my tables are tblSubFlowForecast and tblPickCalendar
I have to update one field in tblSubFlowForecast by taking max(onefiled) from tblPickCalendar.
UPDATE tblSubFlowForecast INNER JOIN tblPickCalendar ON tblSubFlowForecast.Delivery=tblPickCalendar.Delive ry SET tblSubFlowForecast.[Latest Replen Date] = ( SELECT max(Pick) FROM tblPickCalendar WHERE Type="Replen");
I am getting error saying that "Operation must be an updateable query" :(
I have also tried in other way:
UPDATE tblSubFlowForecast SET [Latest Replen Date] = (SELECT max(Pick) FROM tblPickCalendar WHERE tblSubFlowForecast.Delivery=tblPickCalendar.Delive ry AND tblPickCalendar.Type="Replen" ) FROM
tblSubFlowForecast,tblPickCalendar
This is giving me syntax error (missing operator) :(
Can any body tell me why it is giving error?
Thanks in advance
I have a table in Access 2010 and in one field i have multiple records of the same data as in the next field it has unique data for example:
NameColour
CarBlue
CarGreen
CarYellow
BusOrange
BusPurple
BusRed
I am trying to run a query which will effectively group up the "Name" field and combine the "colour" field against the name using a ";". so it would look like this:
NameColour
CarBlue;Green;Yellow
How i would do this.
