Won't Update: Subform Linked By Combo

Apr 6, 2005

I have a form that I have linked (master/child) to a combo box on my main form. I have a requery command for the subform set to the "After Update" event on the combo box. When the combo box is updated originally, the subform updates. However, if the combo box is updated after having a value, the subform does not update.

First off, is the requery command even the right command to use to update the subform? (it's source object is a table) Second, is there a reason it wouldn't work if that is the correct command?

Any ideas?

Update Subform With Combo Box...arg

Oct 18, 2006

This is so simple but I can't seem to make it work. I've poured through about 30 posts and tried all kinds of AfterUpdate event strings to no avail. Help!

Here is the simple setup. I have one table that lists employees and their corresponding teamleader. A grouped query provides the record source for a combo box. The idea here is that you select a teamleader from the combo box and a subform updates to show all the corresponding employees. This subform is based on a simple query of all fields on the table.

combo box = cboteamleader
mainform = frmTechMaintenance
subform = frmEmployees

I've finally settled on this...


Private Sub cboteamleader_AfterUpdate()

Me!frmEmployees.Requery

End Sub


...as having the greatest chance of success based on other posts. Not sure why it doesn't work. It just doesn't update.

Combo Box Based On Linked Table Needs To Pull Info For Sub-Form From Non Linked Table

Aug 31, 2007

I am trying to build a Form that will show an estimate (then eventually will be moved to a project if customer and employee aggree to price and project) in a Form F_Estimates is a M_Customers(Customer_ID) (Based on a Table) and thier info in a Subform. Also is the "projected costs" from parts out of the Parts(Part_ID) (Based on another Table) in a second Subform as a list that I need to calculate $$$ in
(Dang that still sounds evil and definately NOT understandable even after edit... so)

Here's some basic info

Tables

EstimatesandParts - Table
EstimatesandParts_ID : Autonumber
Estimate_ID : Number
Part_ID : Number

Parts - Table
Part_ID : Autonumber
PartNumber : Text (not a number due to some part#s have letters in them)
PartName : Text
Unit Price : Currency
Description : Text

Estimates - Table
Estimate_ID : Autonumber
InvoiceNumber : Text (again can have letters in it)
EstimateDate : Date/Time
EstimateTime : Date/Time
Employee_ID : Number
Customer_ID : Number
ProblemDescription : Memo

Customers - Table
Customer_ID : Autonumber
FirstName : Text
LastName : Text
CompanyName : Text
Address : Text
City : Text
Province_State : Text
Postal_ZIPCode : Text (CDN Postal codes are letter num letter...)

you can see the link table in the EstimatesandParts Table

Now I want to use that link to populate a subform in the F_Estimates form

Forms

SF_Customers - SubForm

(all boxes atm are text boxes on this form till I figure out the Parts section then will use same base for this so I can pick any customer in the database to be the customer for this estimate. Also will have ctrl button for making new customer with customer form and a refresh on Focus Gain bit of code)

FirstName
LastName
CompanyName
Address
City
Province_State
Postal_ZIPCode

SF_Parts - SubForm
Default View -Continuous Forms

(want it to be a list of parts that I can grab prices and descriptions from then in a bit of code to calculate a cost of parts)

Part_ID : Combo Box
Control Source - Part_ID
Row Source Type - Table/Query
Row Source - SELECT Parts.Part_ID, Parts.PartNumber, Parts.PartName, Parts.UnitPrice, Parts.Description FROM Parts ORDER BY Parts.Description;

(Pulls info from the table Parts for input into a list of parts to be used on that project)

PartName : Text Box
UnitPrice : Text Box

(here's where I run into problems due to the fact that the form is not based on the parts table but rather the link table EstimatesandParts so I can't propogate the info to the 2 other text boxes, ps I dont care if they cant be text boxes and have to be linked or some other type I'm not "set" just need to find out how to make it work )

(have tried a couple things to complete this task)

Me.txtPartName = Me.Part_ID.Column(2)
Me.txtUnitPrice = Me.Part_ID.Column(3)

(works AWSOME ... for ONE ROW then propogates the second selection to the first and second and third selection to first second and third and so on ...)

(tried to make control source for the txtPartName to)

=Forms!Parts!Partname

(Doesnt exist .. akkk, cant use ActiveForm either as it doesn't focus on the SubForm but the MainForm ... cry)

F_Estimates - Form

Estimate_ID
InvioceNumber
EstimateDate
EstimateTime
ProblemDescription

(all basic Text Boxes)

Employee_ID
Customer_ID

(Combo Boxes Select Customer and Employee from list of present ones of each)

SF_Customers
SF_Parts

(Both SubForms on the main form)

Now this is an Exerp from my entire Database I like to work on one small problem at a time and I have made this its own little database till I figure out the problem then I will bring the info I learn back into the rest of the database and go from there ...

Hope you can help I have a feeling I will need to make a recordset and go from there but I'm just not able to wrap my head around that for some reason

Thanks in advance for ANY and ALL help that I get from here

Subform Refresh After Combo Update For "<ALL>"

Jun 2, 2005

Hi All,

This is driving me nuts!!

I have a form with a combo box that populates a subform with data equal to the combo box value. I have added "<ALL>" to the combo box to display all records if selected. The after update code changes the queryDefs. The problem I have is that when "<ALL>" is selected, no records show. But the query has updated. If I close the main form and reopen it all the records show, but if I select a new value nothing happpens. But the actual query has updated. I have tried many combinations of refresh, repaint...etc.
Anyway, here is the code, any help appreciated.


Private Sub cboFeedMtrl_AfterUpdate()

Dim qryAllMat As QueryDef
Dim sql As String
Set dbsCurrent = CurrentDb
Set qryAllMat = dbsCurrent.QueryDefs("qryViewData")

If Me![cboFeedMtrl].Value = "<ALL>" Then
qryAllMat.sql = "SELECT * FROM tblMachineSelection"
Me![frmViewData].Requery


Else
qryAllMat.sql = "SELECT * FROM tblMachineSelection where [feed Material] = [Forms]![frmView]![cboFeedMtrl]"
Me![frmViewData].Requery


End If


End Sub

Update Linked Tables

Jan 25, 2007

I've been creating a new Access application and I've run into an issue. The form I created has 2 subforms on it. The data is stored on 3 different tables related by the RMAID. The data gathered from this form needs to go into our MRP application. I have linked the necessary MRP tables to my access application. How do I get the date from the form to the tables in our MRP application? The data needs to go to 3 tables from the MRP application. Do I create an append query that's run after the user completes entering the data on the form? Thanks for any help

Last Update To Linked Spreadsheet

Nov 30, 2011

I export data from a system to an excel spreadsheet, which is linked to my database. When I run reports in Access, is there any way to identify when the linked table was last updated? This would be useful to users if I could add a text box that shows "Data current as of" some date.

Update Linked Table Definitions

Apr 27, 2005

If a front-end database has links to many tables in a back-end database and the back-end is moved, is there an easy way to update all the table links in the front-end in one go, or do you have to set up all the links again one at a time?

Hoping there's a quick way...

Dave

edit: just realised the previous post asks exactly the same thing ( :o ), but that hasn't elicited a solution yet ( :( ).

Update Linked Tables When Used In Queries

Jan 23, 2008

I have set up a table (A) that is linked to another table(B) in my database. This linked table (A) is then used in a number of queries. When the data in the original table (A) is updated it does update the data in the linked table (B) as it should. However, when I run the queries they do not bring up any records. It seems that they are not looking at an updated version of the linked table (A) because if I rebuild the query it finds the records as it should. Any advice on this would be very gratefully received.

Can't Update Records In Linked Table

Apr 2, 2006

I have done everything I can think of to remedy this, but I can't figure out why this is happening. I have a linked table from excel that contains 5 fields for each record. I have a table in access with matching records and 20-30 fields. The linked spreadsheet is used when adding records. I have a query that queries both tables to get all data from both and a form based on that query where others can pertinent data for the records resulting from the query. My problem is that when I open the form the new records that were added in the linked file are there but all the fields from the access table cannot be updated. I have looked every place I know to look for record locks, read only options, everything I can think of why i cannot update these records and I am coming up empty. I checked my join properties and selected the only one that actually displays the linked records when the query is run (not sure the name of the join but it's #2 of 3 join properties options (in Access 2002). maybe I am just overlooking something simple? Do you have any ideas what I can do here?

Thanks!

Forms :: How To Update Linked Excel Graph

May 14, 2014

I have a linked Excel graph in my form. The process I go though to update them is:

User clicks on button
Excel opens up
Procedure in Excel runs that updates the data and the graphs
Excel Closes

The user does not see any of that. This process works fine. But the linked graph does not actually update in the Access Form. To do that I run the following code:

Code:
Set ctl = Me!OLEUnbound_pream
With ctl
' Enable control.
.Enabled = True
' Set Locked property to False.
.Locked = False
' Set Verb property to activate for editing, but not visible
.Verb = acOLEVerbShow
.Action = acOLEActivate
End With

The problem I get is that once .Action = acOLEActivate is ran, Excel opens. I don't understand why it does that and how do I close it.

Tables :: Update Cell In Linked Excel Spreadsheet?

Jan 22, 2015

I have an access database with a linked table to an Excel spreadsheet. I have a form based on the linked table so the presentation of the Excel date is better. The spreadsheet is used by other staff in my office to record sales which I need to register with an external organisation.

Problems With Linked Tables In A Subform

Jan 26, 2006

Hi all,

I am experiencing difficulties with a subform in a database I am designing for a dance group.

First, a little background about the database. There are 2 main parts:
a) a library of CD information and dance information as well as which dances can be done to which songs
b) a tool to plan monthly dance events

Now for my problem:
I have a main form that's built on the PlanProgram table (see attached relationship diagram) and then a subform that runs from the PlanProgramDetail table. Everything works OK up to that point. However, when I go into the subform's record source and add the table Lessons - this is where it "breaks". What happens is when I go back out to the main form and go to enter data in the subform the child field does not behave normally. It doesn't automatically enter the main form's recno_plnprgm number into the subform's field of the same name. Prior to adding the table called Lessons to the subform it did automatically insert the recno_plnprgm number from the main form to the subform.

The reason I want to add Lessons to the subform is so I can update that table's information as well.

Any "fix-it" ideas would be greatly appreciated.

Thanks, Heather

Access - New Record In Non-linked Subform

Nov 12, 2012

I have an access form that has a marco button to open another form using a filter that returns records in the new form that have a matching recordID field from the main form. This works fine.

I want to be able to add records to the table which works as well only the recordID field is not populated with the id field used in the filter from the main form. How can I populate the recordID field with that of the master filed from the main form? It is just blank on the new records created now.

Combo Box Performs Query, Update Combo Box With Only Result?

Aug 4, 2006

Here's the deal:

I'm an extreme newbie, I do not know access very well, nor do I know VBA, I do know PHP.

I have a for in access that has 2 user input fields, one for prodid one for shipid. I have a combo box that upon entering data into the previous 2 fields, it does a query against an MsSQL database looking for a record that has both. In any case there will only be 2 outcomes, either 1 record, or null. I would like to have that same combo box automatically use the result as it's value so that users don't have to check the box, because they won't, and so that the rest of my VBA will be able to function properly.

Can anyone assist?

Thanks.

Option Button Linked With Combo Box

Jun 28, 2006

Morning folks,

Todays problem is as follows!...

Is there away to set the values in a combo box depending on what option button you have selected.

What I would like is to select an option button in an option group then that would trigger certain vaules in a combo box. And if I selected another option button it would change the values in the same combo box?

So if I selected optWhite, the values in cboEthnic = British AND Irish AND Other

If I select optMixed, the values in cboEthnic = White and Black Asian AND White and Black Caribbean etc...

Hope this makes sense.

Split Database. Update Linked Tables If Back End Moved.

Dec 7, 2007

Hi.

I'm about to move to a back end / front end system, from a single database file. Before I do so, I want to make sure I have all bases covered so to speak.

My back end file will reside on a server. I am aware that path names are sometimes changed by network administrators without warning.

From tests, I notice that, if the path to the back end can't be found, one cannot open the front end database file at all (Access 2003).

My question is: if my back end file gets moved, or the path changed, how can I get into my front end file to update the linked tables.

Many thanks in advance.

Mat.
