Global Variable Use
Sep 23, 2005I have 3 different forms, each belonging to 3 different tables. The user is required to enter data on form 1 then form 2 & then form 3. The records on all the 3 forms has to be attached to the same primary key.
The problem is that the user has to enter the same primary key for each form.
I want to be able to carry the primary key entered on form 1 to form 2 and form 3, so that the user does not have to type it 3 times. How can i accomplish this ? Can i call the last primary key entered on table 1 and automatically pop it up on form 2 & 3 every time form 2 & 3 load?
Thanks
Referencing A Global Variable
May 18, 2005I am trying to use a global variable in a dlookup but get an error when i try and run the form
Here is the code:
VUserID is my Global Variable.
Private Sub Form_Open(Cancel As Integer)
Dim UsersName As String
Me.WelcomeBox = UsersName
UsersName = DLookup("[Name]", "tbl Password", "[username] = vUserID")
End Sub
Any Ideas
Global Variable Question
Oct 2, 2006Got a problem trying to reference a global variable in the control source of a text box.
If i do a DLookup when the form opens and have the text box value = the result it works fine ie
Private Sub Form_Open(Cancel As Integer)
Text2.Value = DLookup("UserName", "Users", "[UserID]= " & MyUserID)
End Sub
Where MyUserID is the global variable.
if i put
= DLookup("UserName", "Users", "[UserID]= " & MyUserID)
in the control source of Text2 i get #Name? as a result and if i input
= DLookup("UserName", "Users", "[UserID]= 1")
i get the correct result.
As a test i tried to have the control source = my global variable, of another text box control source with the same result.
It looks like i can only reference my global variable within the VB and not in the forms control sources. Is this correct or can you referece the Global variable in the control source.

Modules & VBA :: When To Use Global Variable
Apr 8, 2014I have an application where several different procedures are run repeatedly every xx seconds to get live updates from a server (different procedures depending which form the user currently has open.) Within each procedure, a separate single procedure is called only if a stored boolean setting is set as true. The setting itself is only changed very infrequently, such as on application startup, but needs to be initially set (i.e. it cannot just have a default of False if it is not set.)Because of this I am storing the setting in a single record table and have a function 'UsingWPilot' to return the boolean value. However, given the frequency that the setting needs to be accessed, and the fact that speed is crucial in the running of the app, I am considering adding a global string variable and modifying the function to look at the variable (possible values 'N' and 'Y') and only going to the table if the variable has not been set.
I have heard various things about how you should never if possible use global variables. My question is: is it faster to use a global variable than to open the table record each time?
option 1 :
Code:
Public Function UsingWPilot() As Boolean
Dim db As DAO.Database
Dim rs As DAO.Recordset
Set db = CurrentDb
Set rs = db.OpenRecordset("rbl_Settings_System")
Option 2:
Code:
Public Function UsingWPilot() As Boolean
Dim db As DAO.Database
Dim rs As DAO.Recordset
If Len(g_WPilot) > 0 Then
UsingWPilot = (g_WPilot = "Y")
Else
Set db = CurrentDb
Set rs = db.OpenRecordset("tbl_Settings_System")

Slow Query Using A Global Variable
Aug 9, 2005Hello,
I have the following query that I set up as a test, and it runs fine:
SELECT STATUSHISTORIE.*
FROM STATUSHISTORIE LEFT JOIN PROBLEM_DE ON STATUSHISTORIE.PROBLEM_ID = PROBLEM_DE.PROBLEMNR
WHERE (((STATUSHISTORIE.STATUSDATUM)<#1/1/2005#) AND ((PROBLEM_DE.DATENBEREICH)='SPMO') AND (((Left(([PROBLEM_DE].[MODULZUORDNUNG]),InStr([PROBLEM_DE].[MODULZUORDNUNG],"-")-2)))='K29') AND ((PROBLEM_DE.ERLSTAND)<>"WEIF"))
ORDER BY STATUSHISTORIE.PROBLEM_ID,
STATUSHISTORIE.STATUSDATUM;
I then set up two global variables ( a String and a Date) and respective functions to return them – ReturnE( ) and ReturnKW( ). Now my query looks like this, but takes ages to run:
SELECT STATUSHISTORIE.*
FROM STATUSHISTORIE LEFT JOIN PROBLEM_DE ON [STATUSHISTORIE].[PROBLEM_ID]=[ PROBLEM_DE].[PROBLEMNR]
WHERE (((STATUSHISTORIE.STATUSDATUM)<ReturnKW( ) ) AND ((PROBLEM_DE.DATENBEREICH)='SPMO') AND (((Left(([PROBLEM_DE].[MODULZUORDNUNG]),InStr([PROBLEM_DE].[MODULZUORDNUNG],"-")-2)))=ReturnE( ) ) AND ((PROBLEM_DE.ERLSTAND)<>"WEIF"))
ORDER BY [STATUSHISTORIE].[PROBLEM_ID], [STATUSHISTORIE].[STATUSDATUM];
My two public functions that return the global variables look like this:
Public gstrE As String 'global variable: contains E used for query
Public gdatKW As Date
Public Function ReturnE ()
ReturnE = gstrE
End Function
Public Function ReturnKW ()
ReturnKW = gdatKW
End Function
The tables are actually Views set up from an ODBC Data source. Can anyone please tell me why these global variables are causing the traffic jam? :)
Thanks in advance

Refering To Global Variable In Query
Mar 15, 2006Hi All,
Can anybody tell me whether it is possible to use a global variable defined in a vb module as part of the criterea in a query, if not whether there is a work around.
I suppose I could temporarily write the data to a table and use it from there, I thought there would be less messing around this way though.
Cheers
Module Variable Global Or Scoped?
Feb 6, 2008I have a variable declared in a module as such
Code:Dim tracking_customer As Double
When i use one form to set the variable like
Code:Private Sub Command83_Click()'Set the global variable to this customer number'So it can be called in "ON OPEN" event in URL formtracking_customer = Me![Customer Number]'gets expected number in following lineMsgBox ("Trackign is " & tracking_customer) DoCmd.OpenForm "Url Tracking", acNormalEnd Sub
Now when I open that next form I try grabbing the newly set module variable but I always get the number 0. So I am assuming it loses the number once I change forms for some reason
Code:Dim trackID As DoublePrivate Sub Form_Open(Cancel As Integer)trackID = tracking_customer'Following line always produces 0MsgBox ("hey this is tracking customer number " & trackID)End Sub
Can someone explain this, and let me know what I am doing wrong please.
Forms :: Global Variable Not Available When Needed
Oct 21, 2013I have this declaration in a module called Global Code
Option Compare Database
Public currentCustomerId As Long
Option Explicit
There is one report that simply prints a the firstname of current customer and the amount of each of his invoices.
The current displayed customer's ID is always copied into the variable currentCustomerId.
Below is the SELECT code of the data source of the report.
But whenever I open this report it asks for currentCustomerId.
Is my decalartion not global enough?
SELECT tblCustomers.FirstName, tblInvoice.Amount, FROM tblCustomers INNER JOIN tblInvoices ON tblCustomers.CustomerID=tblInvoices.CustomerID WHERE tblInvoices.CustomerID=currentCustomerId;
Note: I chose to save the current customer's ID in a global variable because, for some reason, when I select the report the Customer form loses the current customer record and goes to the end of the table as if creating a new customer record. This would not be an issue as long as I can retrieve the value in a variable.
Modules & VBA :: How To See Value From Form As Global Variable
Apr 16, 2015I want to use several values entered in form controls as variables within multiple subs triggered by further form edits. I do not want to define the variables in each sub as this will bloat my code, but I am not being successful in declaring my variables outside of an individual sub, and it is the 'Form!' reference that is throwing it I think.
Here are my variables:
Code:
Dim limit0txt, limit1txt, limit2txt, limit3txt As Integer
limit0txt = Forms!F_Samples_CF_FF_FLot!SF_EnviroCountLimitscntrl.Form!Limit0
limit1txt = Forms!F_Samples_CF_FF_FLot!SF_EnviroCountLimitscntrl.Form!Limit1
limit2txt = Forms!F_Samples_CF_FF_FLot!SF_EnviroCountLimitscntrl.Form!Limit2
limit3txt = Forms!F_Samples_CF_FF_FLot!SF_EnviroCountLimitscntrl.Form!Limit3
If I put these at the top of a module I get an "invalid outside procedure" error message. If I put these in their own module as 'Public' I get the same error. how within a forms code module I can make these variables available to as many events as I like?

View 7 Replies View RelatedSum Of Date/time Variable
Dec 20, 2004Hi Everyone,
I am new here...need your help.
I am trying to sum a field which is defined as a Date/Time field
and is a substruction of Time1 - Time2. at the end of the month, i would like to sum
all these fields in a query. the problem is, the fact that i sget the SUM result as a daily
hour and not accumulated time (i should get like 92:35 Hours, and i recieve 3.45 coz it divids by 24).
How can i format the field to be (like in Excel) an accumulated sum of the hours...is it possible to do
without VB code?
Thank you very much..
PS - Sorry for my bad English
Reporting Time Fixed As A Daily Variable
Mar 18, 2012The previous problem stands solved i.e. ReportTime field shows 9:50 always.But it has created another problem as under
The Formula for ReportTime : Format(Date(),"m/d/yyyy") & " 9:50:00 AM"
The formula for ReportedAt then becomes as ReportedAt: Format(Now(),"hh-nn ampm")
And the next step LateByMinuts:=IIf([StatusID]=1,DateDiff("n",[ReportTime],[ReportedAt]),0)
Where stutusID is
1. Present,
2. AbsentExcused.
3. LeavePrivelege etc.
is correct for the first time.That is when at the first time the Reported time (system time) is recorded it works fantastically but when next time the Form is opened the saved "LateBYMinuts" field is changed with the system date thus disparaging the previous save data.

Apr 16, 2013I am creating a 2 level report to confirm an order. Main report already created, runs successfully called as subform/subreport under "OrderDetails" form. Linked to master using Order.ID. There are two versions of the confirmation report that have different layouts for different program types.

I have tried rebuilding both the main and subreports, rebuilt the query, have not found anything that changes the result.
Linker has been working successfully on other subforms. Report with groupings works fine, but I need data from 2 tables both linked to order.id.

Global Search And Replace
Dec 13, 2006Hi,
My company has renamed a product. I want to find all the records in all the tables in my database that might have the old name, and replace with the new name. What's the easiest way to do this?
I don't really want to have to manually open each table and do a find.
I can write code to go through all the tabledefs and do a find on each one, but the only way I know to do that is by telling it the field name, and field names where the product name might exist vary.
I suppose I can tell it something like
for each TD in tabledefs
for each F in td.fields
{search and replace}
next f
next t
Is this really the best way? I have a program called SpeedFerret, which I thought would do this, but it apparently only searches the table names, not the actual records in the table.
