Modules & VBA :: How To Run A Function In Subroutine
May 17, 2014
I have a database which needs to be updated everyday. So I decided to make a subroutine to perform the update steps just by clicking on a button.
The problem is that I can run all the steps except one! At the end of the steps, there is a function/module that must be run to calculate and complete the job.
How I can run a function in a vba macro. This is my code:
Private Sub cmdUpdateDatabase_Click()
DoCmd.SetWarnings False
DoCmd.OpenQuery "qry1AddNewStockSymbols"
DoCmd.OpenQuery "qry2AddDailyPrice"
DoCmd.OpenQuery "qry3UpdateStockDailyPrice"
DoCmd.OpenQuery "qry4AddOverallStockValue"
DoCmd.OpenQuery "qry5AllSymbolsActiveDaysTractions"
DoCmd.OpenQuery "qry6SortToCalculateDailyRemainedStock"
DoCmd.SetWarnings True
End Sub
I'm trying to run an sql update query (in VBA) to update values in a table, from calculated field values in a subform (using a query as a record source).
Is this possible , and if so, can I call the subroutine from the parent form, and what would be the correct syntax for the VBA sql string (i'm guessing it would be a docmd.runSQL sqlstringname )??
Sometimes I find the 'need' to exit a subroutine from within a control 'loop' e.g. if.. then..else with... while... et al.
I suspect this is 'bad form' but is there any 'cost' in doing this?
There presumably will be if objects have been set and are not reset to Nothing. In this case it presumably is not a problem resetting to Nothing outside a With.. - what about inside a with..??
I want to call a selfdefined subroutine "update()" in several reports. But whenever I try this, Access gives me an Error 2465. The Report is selected dynamically by the user and should adapt itself to other settings made by the user. Can anybody help me how to do this? Thanks.
Is there anyway to have a subroutine be called when a form is brought up? meaning, as soon as the user opens the form, stuff happens without them doing anything besides opening the form.
Hi all. I have a form that opens up another form when you click on a button. The button does more than just open the form, it does other checks. I want to wait until the opened form is closed to continue with the subroutine. Is this even possible in VBA? I was wondering if there was a frmFormName.IsOpen or some kind of flag that would tell me if a form is open or not. Any help would be greatly appreciated. Thanks in advance.
Sub open Checks things Checks things checks things
Opens form(frmDetails) Wait for form to close (THING I DON'T KNOW HOW TO DO IF POSSIBLE)
I am trying to call a subroutine from a VBA routine to append a record to an existing table. Below is the code for opening my recordsets for reading followed by the code creating my table to append to:
Public Sub UpdateLotsizes() Dim curDatabase As DAO.Database Dim ProdPlanDB As DAO.Database Dim rstQryLot As DAO.Recordset Dim rstInvLoc As DAO.Recordset Set curDatabase = CurrentDb
[Code] ....
To call my subroutine, I simply put in the code:
ExceptionReportAddRecord
And this is the code of the subroutine:
Public Sub ExceptionReportAddRecord() Dim rstExcRpt As Recordset Set rstExcRpt = curDatabase.OpenRecordset("tblExceptionReport") With rstExcRpt .AddNew .Fields("item_no").Value = txtItemNumber
[Code] .....
I am receiving "Run-time error 434: Object required" at the line I marked with ...
I have a module for importing several excel files from a folder in Access. The user is prompted to select the folder which contains the Excel files.The issue:The code works fine if I select a folder from my company network drive (strFile variable returns with correct file name).The code does not work if I copy and paste the same folder to my desktop and select this location (strFile variable returns empty)
Code:
Option Compare Database Private Sub btn_ImportData_Click() Dim blnHasFieldNames As Boolean, blnEXCEL As Boolean, blnReadOnly As Boolean Dim intWorkbookCounter As Integer Dim lngCount As Long Dim objExcel As Object, objWorkbook As Object Dim colWorksheets As Collection
We use Microsoft Access databases to enter test data and eventually generate reports.
On 1 computers i get the following error when opening the report:
"Function is not available in expressions in query expression 'Left(.....)"
I figured this is a reference problem so the next thing i did was to pinpoint what reference was causing this error.
It turns out it is the Microsoft DAO 3.6 Object Library. Simply removing the reference and adding it again fixes it and allows you to open reports just fine.
The problem is though, this message comes back every now and then. Which is getting annoying and the person who is making the reports is about to throw his computer out of the window.
I'm having a problem with argument in custom function..My table is like this:
myValues 123.5 32.7 65.8 11.1
What I want to achieve is to multiply each value with the average of all values, so that at the end I get (avg(myValues) = 233.1):
myValues2 7196.963 1905.593 3834.495 646.8525
For this I would like to have a function (this is simplified example of bigger problem, that is why I need function, otherwise simple SQL would suffice as mentioned below also), so that I could do something like this:
'SELECT TestFn([myValues]) as myValues2 From MyTable' or 'SELECT TestFn("[myValues]") as myValues2 From MyTable'
and I should get the table above.
My code is like this
Code:
Public Function TestFn (FieldName) as String Dim myAvg as Double myAvg = Davg(FieldName, "myTable") TestFn = FieldName * myAvg End Function
I understand the problem is that Davg needs string, but if I change to string then the multiplication does not work. The 'FieldName' parameter does not have a Type specified because that is where the problem is if I give string Avg works ,but calculation does not. If I give Number, avg does not work.
P.S. "as String" at the end of function is not a mistake, I need number as a string
P.P.S I did not inculde NZ either as in my example it can never be Null.
I'm trying to delete a file in a network location. Sometimes the file is there, sometimes it's not, so I'm using the following code:
Code: strPath = "etwork driveMy Folder" strFilename = "MyFile.doc" If Not Dir(strPath & strFilename) = "" Then Kill strPath & strFilename
Occasionally, I get a runtime 52 error when the file doesn't exist. I don't understand why I'm getting this when, if the file doesn't exist, the Dir function should return "".I searched the forums for Runtime 52, and didn't find anything pertaining to this.
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 the below function that works correctly. However, I would like the "Last_Nbr_Assigned" value to start at 0000 and increment by 1. So the very first number assigned would be 0001, then 0002, then 0003, and so on.
This number is automatically assigned so I haven't had luck with the validation properties. And if manually enter 0001 for the "Last_Nbr_Assigned", it will automatically cut off the 3 zeros, leaving me with 2 instead of the desired 0002.
Code: Function NewRF() As String Dim startRange_Var As Long, lastNum_Var As Long On Error GoTo Err_Execute 'Retrieve last number assigned for RF groupname_Var = Nz(DLookup("Group_Name", "Codes"), 0)
I started using Access recently and I have an inquiry about VBA codes and sql queries. I have function which has the following signature: RAG(Stability as Integer, DS_SYNC_RATE as Integer, Profile as String) as String.
I would like to call this function in Insert sql query in order to calculate and add a new column to my table. I tried this basic query:
Insert INTO my_table VALUES (RAG(my_table.stability,my_table.ds_sync_rate, my_table.profile))
I have just added a function to a database to strip out any commas or quotation marks from a passed string.
However, it is returning a black string even though when I step through the function it creates the out string correctly and the variable "OutString" is populated when the Exit Function command is executed.
My problem now is about evaluating the result of that query in order to calculate quarterly and annual performances. The query returns correctly:
1) NULL - when I don't have values in the given month 2) 0 - when one of the components of the performance formula is 0 3) value (positive or negative) which can include any positive or negative value
In order to calculate the quarterly values I need the performance of the last month in the quarter and the first month in the quarter. My monthly values are stored in columns so say for Quarter 1, I would need something like this:
Code: [mar]/[jan]-1
As you might have thought, the problems come when I have NULL or 0 values. Let me give you a couple of examples.
[jan] is NULL [feb] is a value [mar] is a value
Than my formula would have been
Code: [mar]/[feb]-1
Second case:
[jan] is 0 [feb] is 0 [mar] is 0
In this case I would like the formula return '-' because I want to be able to spot the case in which the quarterly performance is 0 because the initial values were 0 from the case in which the performance was actually 0 (i.e., say [jan] = 101 and [mar] = 101 then performance is 0 which is different from having [jan] and [mar] = 0 thus performance '-').You can combine the three states (NULL, 0, value) with the three months and find many combinations (I have found 27 relevant ones).
I initially thought to use SWITCH in SQL to evaluate the 27 combinations but I found out that SWITCH would evaluate non more than 15 conditions. So I guess the solution should be use a function in VBA which does what I was about to do with SWITCH in SQL.
I have built a test function which evaluates the numerator of my formula using only two cases (CASE 1: all variables have a value <>0, and CASE 2: the first month is null, the second is 0 and the third a value). Here the code:
Code: Function evaluate_s(Var1, Var2, Var3) As Double Select Case Var1 Case Is <> 0
[code]....
My main question here is what is wrong in the syntax of my function. Why is not correctly evaluating at least the two cases in my function? I always get 0 for all records.
i'm trying to connect to a table valued function on sql (2005) but keep getting the following error: argument are of the wrong type, are out of acceptable range, or in conflict with one another.here's the code
Code: Dim cnn As ADODB.Connection Dim rst As ADODB.Recordset Set cnn = New ADODB.Connection cnn.ConnectionString = "DSN=mydsn;UID=myuser;PWD=mypw;" cnn.Open
In my database when an item is currently being loaned the item's loaned field will have a 1 to indicate this. When the item is returned the value is 0. Only so many items are available and when I use the DCount function it is counting the 0s as 1s.
