Modules & VBA :: Mixing Variable Types
Jul 26, 2013
Dim MooringLines As String
Dim MooringLinesPrice As Double
MooringLines = DLookup("TotalComponent", "ComponentT", "[TotalComponent] = '" & Me.P_MooringLinesCmb & "'")
MooringLinesPrice = DLookup("EuroPerMetre", "ComponentT", "[TotalComponent] = '" & Me.P_MooringLinesCmb & "'")
Me.P_MooringLinesTxt = (MooringLines + " - " + (MooringLinesPrice * Me.P_LengthMLTxt.Value))
In the first variable I'm trying to get a string and combine it with a double in the second. Is it that I can't mix a string and a double in the one variable and if so how do I convert the double to a string?

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

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 have a query which is my list of orders. Now I want to create other type of orders. New types don't use the code in red (tbl Offset and tblRodzajZlecenia). Is it possible to modify the query, in order to keep new types too?
New types of orders are in the same tables. But if I don't fill fields in tblOffset then query can't show new type of oder - that's the problem.
Code:
SELECT z.ID_Zlecenia AS ID, tblRodzajPracy.RodzajPracy AS [Rodzaj pracy], tblRodzajZlecenia.RodzajZlecenia AS [Rodzaj zlecenia], z.NazwaZlecenia AS [Nazwa Zlecenia], k.NazwaSkrocona AS Klient, z.DataPrzyjecia AS [Data Przyjęcia], z.TerminOdbioru AS Termin, tblStatus.Status, tblStatus.lp
FROM (tblKlienci AS k INNER JOIN ((tblStatus INNER JOIN tblZlecenia AS z ON tblStatus.Id_Status = z.Status)
[Code] .....

For reasons I need not get into as it generally proves to be a distraction, I need to document the relationships in databases.
I've been playing around with .Relations with some success.
I can easily get the relationship's name, Table Name, Table Field, and ForeignTable.
Code:
For i = 0 To objDestDB.Relations.Count - 1
With rsMigrateRels
.AddNew
!RelNumber = i
!RelAttributes = objDestDB.Relations(i).Attributes
!RelFields = objDestDB.Relations(i).Fields.Count
!RelFieldsName = objDestDB.Relations(i).Fields(0).Name
!RelForeignTable = objDestDB.Relations(i).ForeignTable
!RelName = objDestDB.Relations(i).Name
!RelPartialReplica = objDestDB.Relations(i).PartialReplica
!RelProperties = objDestDB.Relations(i).Properties.Count
!RelTable = objDestDB.Relations(i).Table
.Update
End With
Next i
However, despite lots of digging into the other properties and attributes associated here, I cannot yet figure out how or where to get the:
ForeignTable field
The type of relationship (1:1,1:many,many:many)

I am now working on this new database. I would like to make a calculation so that I could derive a value called eGFR from a patient's serum creatinine. This is a test of kidney function.I am having the following problems.
a. Modules are not appearing in the Navigation Pane of the Access 2007. When I press 'Object Types' in the Navigation Pane I get all object types such as tables, queries, forms, reports, macros but not modules. I know there are modules as I have written lots of vba code.
b. I have written the following code within this Function. The following is the code.
Public Function eGFR(creatinine, Gender, Age) As Single
If IsNull(Age) Or IsNull(creatinine) Then
eGFR = 0
Else
[code]....
This code is working fine in another database, however when I try to upload a query in the current database that has this function in one of the fields, I get an error saying the the function eGFR does not exit.
I have inserted the function into one of the modules that I have managed to enter.
Do I need to deposit the code elsewhere? How do I access Modules from the Navigation Pane?

I recently upgraded a DB from 2003 to 2013 and ran into the following problem.
I have a button that opens a file dialog box and allows the user to upload a file to a predetermined location (and store the address as a hyperlink). I borrowed this code from someone else on here and modified it slightly.
In any case, the button still works, but now when it opens it doesn't have an option for "All files" under file types. So I can upload MS Office files, text files, etc., but not PDF files which are by far the most common types my users upload.
Here's my code and a screenshot is attached.
Private Sub Command35_Click()
Dim dd As Integer
Dim fileDump As FileDialog
Set fileDump = Application.FileDialog(msoFileDialogOpen)
dd = fileDump.Show
[Code] ....

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?

DIM A1 as String
A1 ="ABC"
END SUB
PRIVATE SUB B()
PRINT A1
END SUB

I 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")
[code]....

I am just in the middle of writting a little bit of code that will go through each record in a query and export it into a word table. It's in the early stages but all was working yesterday. I've come to it this morning and ran it and now I get an error message;Run Time error 91: Object Variable or With Block Variable not set.
Code:
Private Sub Command15_Click()
Dim MyDb As DAO.Database
Dim rsLogin As DAO.Recordset
Dim ObjHead As String
Set MyDb = CurrentDb()
Set rsLogin = MyDb.OpenRecordset("query here")

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
End Sub

What i want to do is coupling data from two different tables together to create one list containing all data.
The two tables are containing info on employees.
List1 contains information like initials, name, home address, employment dates, basically everything except work phone number.
List2 contains initials, name, work landline phone number, and work cellphone number.
I would like to couple the phone numbers from list2 together with the correct person from list1, by looking at the initials on each list and then put it together. I imagine this can be done much like a VLookup in Excel?
I'm guessing this is a very easy thing to do, but i've failed to figure it out myself. Bear over with my horrible Access-skills

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'm working on a module which determines which the previous and next task for the part is. To do this the module finds the first record where the previous field says 'none' and puts the following into variables; the ID for the part (WoTasksFID), The routing number (TaskNumber), the job that is being completed at this stage (Shop), and the task order ID (TaskOrderID). I then want it to find the first record which has the same ID for the part and has a TaskNumber that is one smaller (This is where the error in my code occurs). I record the same variables as before (this time with a prefix "Prev") and use the information to fill the previous and next fields for each record set.
Like I said, the error occurs when I am trying to match the WoTasksFID - instead of finding a field with the same WoTasksFID, it seems to choose the first field in the table no matter the value. Here's the function:
Code:
Function PreviousTask()
Dim TaskOrder As Recordset
Dim WoTasksFID As Integer 'For Current Record
Dim TaskNumber As Integer 'For Current Record
Dim Shop As String 'For Current Record
[code].....
What am I doing wrong?
