Modules & VBA :: Public Function With Variables Referencing Table Date Fields

May 31, 2014

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.

Here is the code:

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

[Code] ....

I am getting a syntax error for the line marked red. How can I use "Between" function in VBA code? Access 2010

Modules & VBA :: Define Global / Public Variables From A Table?

Sep 4, 2013

I would like to declare Global or Public variables from a table so they can be added to or edited easily. I had the following function to do this with Alpha Five but at the moment my lack of knowledge of Access VBA is making this task difficult.

Here is the function that I use in Alpha:

FUNCTION udVars AS A (udTabName AS C )
dim codeStr as c
t=table.open_session(udTabName,file_ro_shared)
t.fetch_first()
while .not. t.fetch_eof()

[Code] ....

It opens a table reads in the records and then makes them into a string the string would look something like this:

"Public EuroRate as Single = 0.885"

I would then need to use this string to declare the variables but not sure what command to use - I was looking at the Eval function last night but couldn't get this to work...

The table would hold strings for all the above so you would have:

My_Var (variable name)
My_Typ (type of variable e.g. Single)
My_Val (value e.g. 0.885)

The table would hold as many variables as required, some would be dates, some paths for making directories and some would be numbers.

Modules & VBA :: Open Recordsets As Public Or Global Variables

Apr 22, 2015

Is there any way of opening recordsets as public or global in a form? E.g. if i do something like

Set rs = db.OpenRecordset("TblCustomers", dbOpenSnapshot, dbReadOnly)

the variable rs should be available in all the private sub i have on that form, and i should be able to access records without opening database/ record sets for individual subs.

Modules & VBA :: Reading Control Value From Public Function?

Oct 4, 2013

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.

Modules & VBA :: Case Select Public Function

Jun 4, 2014

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

[Code] ....

Modules & VBA :: Public Function To Assign A Macro To All Buttons With A Certain Name

Jan 23, 2014

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.

Modules & VBA :: Public Type (variable) For Function To Return More Than One Value

Sep 23, 2014

Question 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.

Modules & VBA :: Public Function - Giving Control Name As Argument

Oct 22, 2013

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 .

Modules & VBA :: Calling Public Function To Backup / Compact Back End?

Dec 23, 2013

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]....

Modules & VBA :: How To Change Controlsource Of Multiple Textboxes With Public Function

Jun 11, 2013

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"

Modules & VBA :: Using Public Function To Feed A Variable String To Query

Feb 26, 2014

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?

Passing Public Variables

Nov 20, 2007

I'm into one of the subforms that will be using the public variable from the main form and am not having success passing the data from the main form over. on the subform, i created a textbox (txt_currentyear) w/ this in the control source field: =[WrkYear] & " Golf Outing"

WrkYear was the defined in a module as:
**********
Option Compare Database
Option Explicit

Public WrkYear As String
**********

I have created a listbox w/ a few years in it (current_year_listbox). this has =[WrkYear]=Me.Current_Year_listbox.Value in the after update field. i loaded the main form, selected the year, went into the subform to see if it passed the data along w/ no luck.

do i need to call or reference that module in every form or report before i can use the data from it? right now, i just get an empty field on the subform.

Would You Make Common Variables Public?

Oct 9, 2007

It just occurred to me that I use certain variables in several of my routines. Maybe you've done the same... something like:

Dim db as DAO.Database
Dim rst as DAO.recordset
Dim qdf as DAO.QueryDef

Now, if it's re-used in many routines, wouldn't it make more sense to make it a public variable, and set them to whatever you need it for a certain routine? Would it be more efficient than having to re-initializing and discarding it for every routine that used it? What problem would one expect from making them public?

Also, since it's very common to set db = CurrentDb, would it also make sense to set it publicly, and for cases where you aren't using CurrentDb, use a private variable just for that one?

Updating A Table Field In A Form Using Public Function?

Nov 13, 2014

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

Public Variables, OpenArgs And Compatability Issues

Aug 10, 2005

Hi all,
I seem to have encountered a strange problem at work.

I declared a public variable for user department. The user selects his department from a Log On form and if the password is correct, he opens another form with the department variable passed on in openargs.

All of this works fine in access2k but upon testing with 2003, the openargs somehow do not seem to be being passed on. Maybe I am being dense somewhere but it is kinda puzzling for me.

I am not using access's security for users and groups because I am trying to reduce the complexity of the whole project (I wont be around to maintain it next time).

Any help rendered is greatly appreciated!

Modules & VBA :: Calling A Function And Passing Variables

May 29, 2015

I have never tried passing variables while calling a function so I don't know what the heck I'm doing. I'll give a simplified example of what I'm trying to do. The second variable vRank is reporting properly but the first one vID gets "stuck" on whatever the first item in the listbox is.

Code:
Dim vrt As Variant
Dim upSQL As String
For vrt = 0 To Me.List1.ListCount - 1
If Me.List1.Selected(vrt) = True Then
Call ChangeUp(Me.List1.Column(0, vrt), Me.List1.Column(1, vrt))

Modules & VBA :: Dcount With Date Variables

Im a relative novice with access VBA, and I'm really struggling with using Dcount with date variable. All I want to do is count if a certain date appears in a table. Here is the extract from my code:

Dim WorkoutDate as Date
Dim datecount as integer

datecount = DCount("[WorkOut Date]", "tblworkoutlogs", "[workout date]= " & WorkoutDate)

Whatever dates are in tblworkoutlogs, datecount is still = 0...I've trawled the net and tried many variations of the code but no success!if I change all the date formats to strings in the code and the tables, it works so I know i'm looking in the correct place.

Modules & VBA :: Initializing Date And Time Variables

Jul 1, 2014

I am writing a process for a hospital application in the UK

We have a concept of "Takes" which are periods to which patients coming into hospital are assigned to and thus the consultant (specialist) who looks after them.

They are fixed times between 0800-2000 (Day take) and 2000-0800 (+1) Night take.

I have written the following function to try and determine which take a patient should be assigned to based on the time now to power various queries to enable the end user to quickly see "today's day take" and "yesterday's take"

Testing it I seem to not be able to hit the right "Take times" in my output. I suspect it's a problem with the way I'm initiating my variables as Today 0800 and Today 2000

Code:
Function GetTakeStarttime()
Dim StartTime As Long
Dim EndTime As Long
Dim CurrentTime As Long
Dim YestStartTime As Long

Calling A Public Function From A SubReport

Oct 2, 2004

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

--------------------------------------------------------------------------------------
Private Sub GroupHeader0_Print(Cancel As Integer, PrintCount As Integer)
Dim widthOfBox, startLeftSide
startLeftSide = 0.017
widthOfBox = 0.21

Me.ForeColor = 0
'Repeat the following line of code for each vertical line
' 1*1440 represents 1 inch

' Me.Line (0 * 1440, 0)-(0 * 1440, 14400) 'Draws line at Left Margin

Queries :: VBA Public Function As Parameter?

Feb 13, 2015

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?

Public Function Percentile_(fldName As String, _
tblName As String, p As Double, _

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?

Modules & VBA :: Add Records To A Table Referencing A Table In Another Database - DAO

Jan 16, 2015

I am using Access 2010 and I currently use a command button on a form to add new records to a table using data that the user has entered into the form using the code below:

Although this is pretty self-explanatory, here is a key for reference:

Me.lstFacilities = ListBox
Me.cboMeasure = ComboBox
Me.cboYesNo = ComboBox
Me.txtTarget = TextBox

Code:
Private Sub cmdAddMet_Click()
Dim DB As DAO.Database
Dim RS As DAO.Recordset
Dim strSQL As String
Dim i As Integer
Set DB = CurrentDb

[Code] .....

This works great but I would like to be able to pull in data from another database based off of Me.lstFacilities.Column(1, i) which is the FACILITY_ID field and is located in the other database's table. I thought about adding in another string variable(strSQL1) and opening up a separate recordset and database:

Code:
Set DB1 = OpenDatabase("serverotherdb.accdb")
strSQL1 = "SELECT [FieldName] FROM [tblOtherDatabase] IN 'serverotherdb.accdb'"
Set RS1 = DB1.OpenRecordset(strSQL1)

However, I'm not sure where to start pulling in the data from the [fieldname] in the [tblOtherDatabase] when I start the loop below:

Code:
For i = 0 To lstFacilities.ListCount - 1
If lstFacilities.Selected(i) = True Then
RS.AddNew
RS!RELATIONSHIP_ID = Me.lstFacilities.Column(0, i)
RS!MEASUREMENT_PERIOD = Me.cboMeasure

[Code] .....

Is it even possible to do this?
