Modules & VBA :: Public Variable Passed Back To Private Sub
Sep 26, 2014
I've got a private sub that runs when the form loads. I want it to get the id of the record which has opened this new form.
The public sub populates the variable but it's Empty going back into my private sub. I'm sure its a simple school boy error but it has me stumped!
I want it public as I need to keep that id as new records are added in the form.
Private Sub Form_Load()
FRStudentFundingRequestID
'fundingrequest = FundinRequestID
Me.txtFKFReq = FundingRequest
End Sub
__________________________________
Public Sub FRStudentFundingRequestID()
FundingRequest = [Forms]![frmFundingRequest]![txtpk]
End Sub

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" :/

Is it possible to open another database, set a Public boolean variable in a module?
in db1: Open database by Access.Application, OpenCurrentDatabase, setting obj to db2.CurrentProject, loop through main objects
in db2: Public ByPassCloseVar As Boolean is in a module ModLinkTblReview
I have a process that opens up a database runs through all of its objects to get their properties and values. There is a form that is set up on Unload to close the tool if the variable is set to False. When I open the form to get the properties and their values, then close the form, it closes the database. I would like to set the variable to true in order for the database to stay open.
Thought something like this would work: db2.Modules!ModLinkTblReview.ByPassCloseVar = True

I have a module that has a global variable defined as shown below
Module: initGlobals
-----------------------
Code:
Option Compare Database
Option Explicit
Public strGlobalUserId As String
Sub initvar()
strGlobalUserId = "Myuserid"
End Sub
This is invoked in a login form("frmLogin") and it displays the above value before I replace it with the one that is accepted in the form.
Here is the code from the login form
Code:
strGlobalUserId = Me.cboEmployee.Value
When the password is successful, I close the login form and open a form called "frmMainForm". In the form_open event of the "frmMainForm", I am trying to display the user id using strGlobalUserId but it just has spaces. What am I doing wrong?

I have a backup subroutine which automatically triggers when the front-end is closed down (it just takes the back-end, makes a copy and compacts it).It's driven off a hidden form which I use to track who is connected to the BE at any given time. This form is opened as part of the AutoExec when the FE is opened and writes some basic user info to a table. When the form is closed, it updates the table and fires the backup process before quitting Access.
Part of that user tracking process checks to see if the same user is already connected - either elsewhere (i.e. on a different machine) or on the same machine (i.e. opening a second instance of the same FE) - which is undesirable (and, frankly, unlikely, but not impossible) A brief prompt appears to explain that they can only be connected once, at which point the application is quit (to enforce the rule) This also works fine.
I would add a public boolean variable, set it to True by default, then switch it to False if the same user is already logged on before quitting Access.Trouble is, the variable doesn't seem to be holding its value? Here is the Load event for the tracking form :
Code:
Private Sub Form_Load()
On Error GoTo ErrorHandler
Dim dbs As Database
Dim rst As Recordset
Dim strSQL As String
Call InterfaceInitialise
blnPerformBackup = True
[code]...
For some reason, blnPerformBackup is False every time, even though I set it to True at the very start of the Load event (and it is a Public variable, defined in a separate module where I store all my Public constants and variables)
why it is not retaining its value from the Load event? I've checked and it does get set to True - and when I debug, it remains True - but at runtime it reverts back to False by the time it reaches the decision whether to backup or not?

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]....

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.

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?

I have some code in a form that calls for a public function and passes on some values. the function makes some calculations and assigns a value to the variable "percent" in the function itself.
How can I get the value of this variable back in the form so I can use it?
Form:
Code:
Private Sub Form_Open(Cancel As Integer)

I have code that from DB1 opens DB2 and runs a Function in DB2.
The DB2 function produces a Boolean result that i am trying to get back to DB1 without success. Below is the script.
Sub Test22()
Dim AC As Object
Set AC = CreateObject("Access.Application")
rc = "K:ARSHRAutomation_ProjectsMikeFEDB2.accd b"
AC.OpenCurrentDatabase (rc)
AC.Visible = True
AC.Run "SendVariable"
End Sub
Because i am using AC.Run "SendVariable" i cant find a way to get the value of SendVariable!!

I have a form set up where a user chooses a page tab. Either statistical reports or detail reports. Then they have to choose between 2 toggle buttons. Candidate or hire.
So a user chooses detail, then candidate. An option group below that shows the different groupings of detail candidate reports that they can choose.
A couple of examples - detail report of candidates by office applied to, department, application source etc.
Once that is chosen a button is visible to continue. Now they are taken to the appropriate form. This is done by a global variable gstrformname defined in the afterupdate of the group option that they chose (office etc.)
Once they click to continue to the criteria form, they are choosing the criteria. (for example purposes) the choice below takes the user to a criteria form for choosing an application source ( email, monster.com etc) or click a button and all types are given. I have all of that set up. But now I want to change what report the command button is opening, to a variable. A variable that would be set by the below form when the type of report and grouping for the report are chosen...that defines a certain report.
I specified on this main report menu that it is a candidate report that I want, but when I get to the criteria form, I need a way to pass that choice on. I am not sure how to best do that.
I am trying to avoid making 2 copies of the same form 1 for candidates and 1 for hire. :crazy: I undertstand that I should pass a variable here.
So basically on the main form they choose candidate or hire report, then they choose group. The grouping information tells the command button what form to open (the application source criteria form, the office criteria form, etc). The thing is, this form is the criteria for the candidate report and the hire report. The command button on the criteria form would ideally be -
docmd.previewreport gstrreportname, acpreview
my question is, how or where do I define, from the point that they choose candidate or hire, to the next form, that they want the candidate by office or hire by office report? (define the gstrreportname variable as one of those too.)
Make sense?
Here is a pick of the report form (menu)
http://www.geocities.com/misscrf/reportmenu.jpg
For the afterupdate of the frame for the grouping of the report, I have a select case. In that I define gstrreportname for the report it is, if the choice goes right to a report. If it goes to a form first (for criteria), I define that form with a global variable gstrformname. Can I also define the report there (gstrreportname)? If I do that, will the criteria form know that? Even if I close the main report form?
I hope someone understands me! :shrug:

Not sure if I am asking the right question, but....
I would like to pass a string variable to a query but it does not seem to work.
In the query, my criteria for the date field is (and works):
>=[forms]![frmDisposition]![FromDate] And <=[forms]![frmDisposition]![ToDate]
But, this is not working for the ID field criteria:
[forms]![frmDisposition]![ID]
In the forms code, I have a string based on the result of 3 check box. I tried using an unbound (ID) control to display the string so I know that the value of the string is correct. EX: "FW" Or "MA" Or "PD"
Is it possible to pass the value of the string to the query or do I need to try and pass the value of the unbound control to the query?

I am working on a database where I want some specific information displayed on a form, preferably on the form header. I want to display this on all of my forms. In a standard module, I have a code segment that runs a query returning values, and I assign those values to my public variables. I run this code segment triggered by "on activate" of each form.
The variables contain an Event Date, and an Event Name. I want this information to appear on each form. How do I get this data onto my form as part of the form header, or if cannot put on header section, then in the detail section?

Okay I have a Private Sub on form PlotF:
Code:
Private Sub SetCheck212()
If Me.[Check161] And Me.[Check169] And _
Me.[Check167] And Me.[Check181] And _
Me.[Check261] And Me.[Check189] And _
Me.[Check187] And Me.[Check195] And _
Me.[Check203] And Me.[Check201] Then
Me.Check212 = True
[Code] .....
Some of the checkboxes are locked as I want to force the user to check them on another form (InvoicedF) but I want them to be displayed PlotF as well.
So I want to call the Private Sub from another form. So that the Check212 still automatically checks to true with out PlotF open on the screen.
Is this possible, Do I have to make this private sub a public sub? If so how do I do this?

I have a after update event that will match the written record with any exist record in a table in the field "OrgName". If it doesn't find exact match, will call a function with a "soundex" algorithm to see if there is only a misspelling or another name altogether.
In the afterupdate event, I have a string called strOrg (wich is the name I want to compare).
I have the soundex function in a module, so I can use it for several form generally.
What I want is to pass the strOrg to the soundex function, however I don't know how to declare the variables. however I keep having this error:
"compile error: Argument not optional"
and goes to the line tagged as 1 in the private sub afterupdate
The afterupdate sub is the following:
Code:
Private Sub tOrgName_AfterUpdate()
Dim strOrg As String
strOrg = Me.tOrgName.value
If IsNull(DLookup("orgID", "torg", "OrgName = '" & strOrg & "'")) Then
resMsg = MsgBox("This organization name is not in the list. If you want to look for similar names press YES, if you want to register a new organization press NO.", vbYesNoCancel, "Organization not found")
[Code] ....
and the soundex function is declared as
Code:
Public Function Soundex(strOrg As String) As String
Dim Result As String, c As String * 1
Dim Location As Integer

I have a form that allows you to search for records and displays all the information for that project, typical stuff.
On this form is a subform with the followings Fields:
Inspection Requested, Inspection Due, Inspection Done, Overdue
When you update inspection requested the inspection due is automatically updated to 30 work days from that day.
Now what I'm trying to do is get the overdue field (it's a yes/no field) to automatically check itself when the current date is passed the inspection due and the inspection done field is blank.
Here's what I have that isn't working:
Code:
Private Sub Form_Current()
If DateAddW([REQUEST], 30) < Date And [INSPECT DONE] = 0 Then
[OVERDUE] = True
End If
End Sub
DateAddW is a UDF that works just fine. I've tried replacing 0 with Null and neither works.

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.

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.

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 .
