How can I define a variable which can be used by another Sub and of course the value stored in it?For instance:
Private SUB A ()
DIM A1 as String
A1 ="ABC"
END SUB
PRIVATE SUB B()
PRINT A1
END SUB
Is it possible (and how...) to declare a module-specific form variable (or any variable for that matter) at the top of said module, so it doesn't need to be set at the start of each subsequent procedure?
I have a module of code specific to one form with a number of procedures, each one of which requires me to Dim / Set the form variable. It would be much neater if I could do it once at the start.
Code:
Option Compare Database
Option Explicit
Public Sub Populate(lngParameter As Long)Dim frm As Form
[Code] ......
I have a form (Datasheet). I need to define some variable in form as string, which can work with any event. E.G in column "A"on event after update, in column "B" on event after update...
I will try to explain with a simple example : form (datasheet) columns: "A", "B"
on event after update in coulmn "A", I could have some like this:
(variable what I need to define) = 3
on event after update in coulmn "B", I could have some like this:
If (variable what I need to define) = 3 then
msgbox "ok"
end if
Now I try to work around the problem and use another column "c" to keep the value from after update A - but I know that, it's bad solution -Right?
I have one color scheme I want to use all through the database I am developing. The next examples have just one color defined, to make it simpler (a dark blue, that I would call B1)
Code:
private sub setlabel()
Dim B1
B1 = RGB (0,52,105)
me.label1.forecolor = B1
end sub
... however this means I have to repeat the color definition every sub, so I thought would be neater to define a function to set my color codes (I have 20 colors).
Code:
Function SetColor()
Dim B1
B1 = RGB (0,52,105)
End function
My objective, is when I'm working in forms, Iwould (ideally) call this function "setcolor" and just write my code for the blue. I tried the examples below:
Code:
Private sub setlabel()
SetColor()
me.label1.forecolor = B1
end sub
[code]...
Again, this is probably some definition of arguments or dimensions that I am not aware oh. How to predefine the colors in a function to give them a "short" code which I can call in any sub in the database?
I have a multi-user database. I would like based on the logged-in user, some buttons and controls in different forms be disabled and the others be enabled.
There is a login form that gets the username; I made also a function to define authorities for users in it.
My plan is that when user enters to the database, on load of the main menu the function calls and disables the defined controls in different forms. I tried to use this kind of codes:
Function User_1()
[Forms]![frmMainMenu].[cmdUpdateDatabase].Enabled = False
[Forms]![frmChooseReports]![cmdOrdersFollowUpReports].Enabled = False
End Function
Function User_2()
[Forms]![frmMainMenu].[cmdChooseCharts].Enabled = False
End Function
But this code only works for the forms that are opened at the moment and if one of them is closed the system gives Error.
I have a table which is formatted as shown:
ID, My_Var, My_Value, Notes
This table holds variables that I want to declare to use throughout my application. I have been told in another thread that tempVars are the best way to do this.
I have written the following code, which works on a limited basis:
Private Sub btnSetVAr_click()
TempVars.Add "udvVar", Me!My_value.Value
End Sub
This defines a single variable on each button press, fine to work out how the code works, but not much use. What I really need to do is when the initial menu screen loads to call a routine to assign all the variables stored in the table using a loop to do this. The idea is to make all variables values easy to edit or add to, rather than have to edit code each time we need to change them.
The variables table holds 14 records so far, such as:
My_Var, My_Value
EuroRate, 0.885
ConDisc, 0.9
MollDisc, 0.8
As well as holding numbers, they hold strings and date values.
So, on loading the initial form, use an event to assign the variables from the table using the tempVar name as the value held in "My_Var" and it's value as held in "My_Value"
I am trying to define a path to identify a current folder - I'll try and explain the way the following code works first (and it does work 100%)
The following code identifies folders and sub-folder structures and imports them (their structures and folder paths and filenames) into a DB
It also simultaneously retrieve's any xml docs within those respective folders and imports the XML data into the same database ........ and then moves those folders into a "processing folder" location.
Cool yes, but I can only import the XML doc's at the moment, by hard coding the path (like this):-
path = "C:UsersjeremybDesktopsnapmadXYZ123XYZFILES 0061940"
The code is highlighted as above - in the FULL code below:

Error 91 - Object variable or With block variable not set
I am getting this error telling me that an object variable is not set.
I know which variable it is but when I step through the debugger it sets the variable and all is fine? Issue is that public variable of a class is not getting set when the VBA Editor is not open?
This code runs fine the FIRST time, however trows up a message the SECOND time it is run.
The error is on the line ".Range"
I am trying to sort records which have been exported to Excel.
Dim LR As Integer
LR = 5
Set xlApp = CreateObject("Excel.Application")
xlApp.Visible = True
Set wbRef = xlApp.Workbooks.Add
With wbRef
wbRef.Activate
.Worksheets("Sheet1").Activate
With ActiveSheet
.Range("A2", .Cells(LR, "O").End(xlUp)).Sort Key1:=.Range("C2"), Order1:=xlAscending, Header:=xlYes
End With
end With
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.
I look at a lot of files to see when they were last updated. I wanted to write a generic procedure to manage that so ..
Code:
Public fDate As Variant
Public vField As String
Public vFile As String
'GTSdata
vField = "txt_gts_data"
[Code] ....
What I hoped Me.vField would do is update the date field [txt_gts_data] on my form with the date the file was last saved.
i.e. me. txt_gts_data = fDate
What actually happens is the variable vfield gets updated from "txt_gts_data" to 19/08/2014 then later code falls over because the fieldname is lost .
Me.[vField] corrects itself to me.vField (and does not work)
Me!vfield falls over (cannot find the field vField, not surprising J)
How do I say update the contents of the variable, not the variable itself?
I need to find the respective numbers for a textstring when for
abcdefghijkl stand the numbers
79 81 82 83 84 85 86 87 88 89 91 92
The textstring to "decode" is for example is 'adgjk'
The result (79 83 86 89 91) should be added into a table by Looping.
rs.Addnew
rs("Letter")= myarray??
rs("corNumber")= myarray?
rs.update
rs.movenext
Something like this.
But I cannot define and Setup the Array, which should be the best way for doing this.
The Array does not change its Content nor its Dimension.
Both, letters and numbers are strings.
If I set a variable inside of a subroutine, it is set to nothing upon the end of the sub. Can I set a variable outside a sub and set its value, so that you can use it within subs?
View 14 Replies View RelatedI 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")

I have some code that will allow a user to pass to it the name of a report. The code will do various things to that report before presenting it for Preview, opening in Word etc.
At one point in the code I would like to refer to some control or property of the report. If I was to include this directly for one report, I might type:
Reports!Annual_Budget_Report.Recordsource = xyz
But instead of a specifc report, it would be the report as a variable (srReport_Name). However, if I type:
Reports!stReport_Name.Recordsource
The code complains, rightly, that there isn't a report called stReport_Name. The stReport_Name variable is currently set as String. I *think* the answer might lie in the variable type, but I'm still struggling.
I have a form in which am gathering information from the user to populate a table(Customer Master List) and at the same time (btn_Copy_Click Event)transferring the info to another form(Case) populating another table(Customer_Call). It is working fairly well, My issue is that before transferring the info I need to run a check(SQL Query) to make sure the customer or actually the Well ID don't exist in the Customer_Call table. I am trying to do this in pieces .....
1) capturing the well_Id in a variable(WellID) in the first form and using that to build the sql string and query the Customer_Call table.
2)once that works place it in a if / else clause to copy or not with appropriate messages
With that I am stuck in step 1
It works up until Set rst = CurrentDb.OpenRecordset(strSQL) the i get Run-time error '3061' Too few parameters. Expected 1.
Code:
Dim WellID As String
Dim strModel As String
Dim strSQL As String
Dim rst As DAO.Recordset
WellID = Forms!f_Customer_Lookup.Well_ID
MsgBox WellID ' testing to see if it picks up the correct box in form
strSQL = "SELECT Customer_Call.[Cus_Well_ID] " & _
"FROM Customer_Call " & _
"WHERE Customer_Call.[Cus_Well_ID] = WellID;"
Set rst = CurrentDb.OpenRecordset(strSQL)
strModel = rst!Cus_Well_ID
rst.Close
MsgBox rst ' Testing to see if the strSQL captured the data
Set rst = Nothing

I use a macro that attaches a document automatically to an e-mail address ready to send this report is governed by a query of which the criteria is " loss order number " this is in a pdf format of which I need if possible
The problem I have is the same pdf file keeps attaching itself to the e-mail no matter which loss order number I select. The reason I think is because the report is called NCR so it is not changing from the previous one. What I think can solve it but not sure and don't know how to do is get the " loss order number " within the report name.
If I just send the report to a file direct it does work as I am prompted for a file name
Can the loss order number get into the file name within a macro/vba
Code:
Name="EMailDatabaseObject
Name="ObjectType">Report
Name="ObjectName">SEND NCR
Name="OutputFormat">PDF Format (*.pdf
Name="To">=[E-mail Address] & IIf(Nz([E-mail Address
I have the following simple variable assignment...
Dim PolRef As String
Let PolRef = Me.Policy_Ref_Num
But when I run my code I get "Invalid Use of Null" and PolRef is set to ""
This field is populated however, so I'm confused to why I cant set my variable to it.
If I don't use a variable and simply have let XXX = me.Me.Policy_Ref_Num then it still wont return the value from the field.
I want to get the output of a vba query (only one solution possible) in to a variable but the variable stays empty.
Dim rst As DAO.Recordset
Set rst = CurrentDb.OpenRecordset("SELECT info FROM evaluationtable WHERE evaluation= " & evaluationchoice & " ")
var = rst(0).Value
rst.Close
some explination: evaluation and info are fields of evaluationtable evaluationchoice is a field in an accessform where I can choice a value from the evaluation field
the table is build as this (only two fields) evaluation - info
Why does this work when the text box is used and not when the variable is used directly?
Code:
Private Sub Command61_Click()
Dim strDBName As String
strDBName = getDBName()
Me.Text59 = strDBName
Me.Text62 = DLookup("[ModuleName]", "tblModule", "[DatabaseName] = text59")
'Me.Text64 = DLookup("[ModuleName]", "tblModule", "[DatabaseName] = " & strDBName)
'Me.Text64 = DLookup("[ModuleName]", "tblModule", "[DatabaseName] = strDBName")
'Me.Text64 = DLookup("[ModuleName]", "tblModule", "[DatabaseName]" = strDBName)
End Sub
Text62 returns the correct value
Text64 failes on everyone of the examples
I am trying to set the following variable that will be used to create a PDF file in an already existing folder and name the file WorkorderIDddmmyyyy-hhnnss.pdf
The following variable setting creates the filenameddmmyyyy-hhnnssWorkorderID.pdf.
mFilename = "C:RPR AccessPDF Reports Emailed" & Format(Now(), "ddmmyyyy-hhnnss") & WorkorderID & ".pdf"
DoCmd.OutputTo acOutputReport, mReportName, acFormatPDF, mFilename, True
I just can't figure out how to construct it correctly.
Also, is there a way to dynamically create a folder if the folder doesn't already exist? I currently hard code the folder name but would really like to create the folder name based upon some other variable.
I have a form which load data from variables in record set where i can make insert update and delete i need to load sub form when the form load the problem is that all text boxes in main box load from variable which are in rerecord set and how can navigate using navigation buttons in main form.
