Using Syscmd(... Update Meter)

Oct 12, 2005

I use syscmd(acsyscmdInitMeter) and syscmd(acSysCmdUpdateMeter) frequently. I noticed that the acSysCmdUpdateMeter has two arguments. I know the first one updates the counter, but I have not found any documentation for the second. Does anyone know how it can be used?

I would like to modify the Status Bar description that is set in the InitMeter action with the UpdateMeter action. Is there any way to do this? For example:

syscmd(acSysCmdUpateMeter, "Part 1", n)

syscmd(acSysCmdUpateMeter, "Part 2", n)

Thanks for your help

Progress Meter

Mar 30, 2005

I have a form that, when I press a button it loads another form. The second form takes about 20-25 seconds to load due to the fact that the (split)DB is running over a network, and the form itself has many fields on it. I'm thinking that my users will think that their computer is locked up and keep closing out of the DB. I would like to add a progress meter or percent meter so the user will at least see that something is happening. Has anyone ever programmed one of these things, and if so, could you please give me some insight? Thanks.

Review - Table Design - Meter Reading / Adjustments

Aug 3, 2005

I am working on a database to keep track of meter readings from several meters. Am at the table design stage and have come up with two seperate table designs but am wondering what would be best.

Each individual 'Meter' tracks more than one 'Fuel'. All of the regular meter readings should occur on the last day of the the month. The difference between the current month's reading and the reading from the previous month is the usage for the current month.

Though rare, there are occasions when there could be adjustments to the meter. A meter may be reset to 0 or to any other number due to a number of issues (replacement, maintenance).

The usage for a Meter-Fuel combination calculated by the current meter reading & previuos meter reading is assigned to current readings' date, As readings should onlt be taken at the end of the month, all other readings should be adjustments ONLY!

Here is my one version;

tblMeter
MeterID (PK)
strMeterDesc

tblFuel
FuelID(PK)
strFuelDesc

tblMeterReadings
MeterReadingID (PK)
dtMeterReading
MeterID (FK)
FuelID (FK)
dblMeterReading

tblMeterReadings
MeterReadingID (PK)
dtMeterReading
MeterID (FK)
FuelID (FK)
dblMeterReading

tblMeterAdjustments
MeterAdjustmentID (PK)
dtMeterAdjustment
MeterID (FK)
FuelID (FK)
dblMeterReadingOLD
dblMeterReadingNEW

My other idea was to incorporate meter adjustments into tblMeterReadings and not have a sepereate table for meter adjustments

tblMeterReadings
MeterReadingID (PK)
dtMeterReading
MeterID (FK)
FuelID (FK)
dblMeterReading
blnAdjustment

The I would create a multi-field index of dbMeterReading, MeterID, FuelID, blnAdjustment.

So data with an adjustment may look like this

dtMeterReading, MeterID, FuelID, dblMeterReading, blnAdjustment
01/31/2005, 1, 1, 900, False
02/15/2005, 1, 1, 1000, False
02/15/2005, 1, 1, 0, True
02/31/2005, 1, 1, 100 , False

I think that the second version is the way to go, since I would still have to create a query to join data from both the reading and adjustment tables in the first design that would look like the data above.

Here what I consider to be the drawbacks to either table structure

Version 1
The first version requires more complicated queries to calculate the difference between meter readings.

Version 2
The second version will require some coding/querying to make sure that there are always two adjustment records for one date and determining which is the pre-adjustment and post-adjustment meter reading since it may not be true that the meter is reset to zero; it may even be set at number higher than the pre-adjectment reading.


Any thoughts on which design is better? Or any problems I could run into later with designing forms/queries/reports that perhaps I have not thought through?

THANKS!

General :: Meter Reading Table - Calculation Based On Previous Record

Aug 2, 2013

I have a table full of meter readings. I want to have a field called consumption which looks at the reading just entered for that month and then subtracts the previous months reading for that meter which leaves the consumption.

Can I get a formula that can work this out automatically?

General :: Saving Data - Update Or Cancel Update Without AddNew Or Edit

Apr 13, 2013

My membership database has worked fine until recently. Now I cannot save inserted data. On attempted saving "Update or CancelUpdate without AddNew or Edit" appears.

The problem. relates to 2 tables Member and Addresses. PK in the parent table Member is ID. In the Addresses Table the FK is ID. There is a One to One relation between the tables and Referential Integrity is set. I know 1 to 1 is not good but it worked fine in this small database.

Browsing the all of the existing records is fine.

Update Queries Update Message

Mar 30, 2006

I am trying to stop access displaying the "You are about Update 1 Record" etc message when i run an update query. I know i can do this in Tools/Options screen but the problem is that the database is going to be used by multiple users, and rather than changing each persons Action query option I was wondering whether there is something i can put in to the code Globally to halt the message.

Any help would be appreciated.

Update Query Won't Update In Access 97

Feb 10, 2008

I am trying to remove random characters from a field. The field [assycode] contains a string similar to say, FGEJBF1 or ABFGYRUKC I want to remove any occurrence of "F1" normally at the end of the string but not always at the end. I used: Like "*f1*" to find the correct records, that worked fine, I then used [Assycode]-" f1" in the update to box, It wants to update 146 records I click ok then it says It couldn't due to a type conversion error. Just messing around I tried adding "F1" to these records using [Assycode]+" f1" and it worked fine. Can anyone point me in the right direction?

Thanks in advance

Using Update Query To Update Values

Oct 3, 2007

I have a database where two tables contain information that I need to update based on the 4 right most digits of a field. There are only 11 values that will need to be updated out of a large list of values. I'm not quite sure how to set up the update query so that I can do this.

General :: Update Record ID To Another Record ID In Same Table And Update Related Records

Aug 22, 2013

I have a table called tblCompanies. When a company acquires another company, I need a method by which the acquired company's CompanyID (PK) can be updated to the new company's CompanyID (PK). I also need to be able to update all related CompanyIDs (FKs) to the new value in related tables.

In cases in which the new company does not have an existing record, there is no problem: the company name simply gets changed to the new company and the existing CompanyID is maintained. I then use an audit table and Track Changes function to keep track of the company name data and a union query to keep the old names in the selection lists.

The problem is when both companies already have existing records in the table.

So, let's say I have records for Company A and Company B. Company A merges with Company B and Company B is now the main record. What is the best, simplest and easiest way to update the CompanyID (PK) from A to B and change the CompanyID (FK) to the new value in all related tables?

I am envisioning a pop-up form that directs the user to select the new company and then an update query happens behind the scenes... but exactly how does the criteria for the update query get selected and how do all the related tables get updated? My vba skills are pretty basic, will I need extensive coding to do something like this?

Update Query Will Not Update!

Aug 16, 2005

I have two tables, each has a "status" for a project. In the left table there is only one instance of each set, but in the right hand table, each set may be used more than once by different Projects.

I need the Status field of the left table to be set to "Assigned" if ANY of the sets assigned to projects in the right hand table are "Assinged"

Here is the update query I have setup but when it runs, it updates "0" rows.

8 is the id for the status "Assigned" in the SetStatus table
2 is the id for the status "Assigned" in the Status table.

Before Update, After Update...????

Feb 2, 2005

I can never get this right and it's frustrating.
I have a field on the form called OverallProjectStatus - it's a combo box and it has values: green, yellow, red.
If a user selects green as a value I would like BackColor of the form to turn green color.
I tried both before update and after update events on this combo box as well as on the form's before and after update events and it's not working.
Could someone please help me put this code in the right place.
If Me.OverallProjectStatus = "Green" Then
BackColor = 13434828
End If
Thanks!

After Update

Feb 10, 2005

Can someone tell me if this is the correct/best way to do this.

I have a calculated field "savings". It is calculated on the AfterUpdate event of the "month" field.

I have 2 text boxes (std cost & quoted cost) that have manually entered amounts and one combo with "modules" To get the savings calculation my code looks at the month selected then the module selected in my query and sums up the volumes.

It then multiplies the volume X the std cost minus the quoted cost.

Std Cost Quoted cost Dif Volume Savings
3.00 1.5 1.5 200 $300

Anytime any of the four fields change (std cost, quoted cost, module or month) I need the Savings field to recalculate.

My first thought is that I need to put in the same code calculating the savings in the AfterUpdate event of all of these.

Is that the case? What better way is there?

Thanks!

I have tried things like....

[Forms]![Frm1].reload
[Forms]![Frm1].refresh

But cant seem to get it to work. Any ideas?? Thanks

Update SQL

Jan 12, 2005

Hey Guys,

I had a problem a while ago about changing the value in one field and having it update a different field in another table.

I have a table Order Details where I want the user to be able to select a quantity when ordering a particular shoe.

I then want a field named UnitsOnOrder in a table Products to update its value based on the amount ordered by the user in the quantity box in the other table.

The Order Details table is a subform not that it makes any difference.

I started receiving help by a Mr M Walts, but he hasnt been around for ages and I'm so very deperate for a fix as the code isnt working correctly and I've no idea how to fix it.

Private Sub Quantity_AfterUpdate()
'will hold the SQL which will update the Products table
Dim strSQL As String

'will hold the new total quantity after the change
Dim intChange As Integer

'see if the quantity had a previous value, might have to seperate into two
'nested if's if it gives an error on the second part of the condition
'when OldValue is null. It might
If Not IsNull(Quantity.OldValue) And (Not Quantity.OldValue = "") Then
'ok, there is a previous value, let's see which is bigger

'the change will be the new value - the old value
intChange = Quantity.Value - Quantity.OldValue

'ok, now we have the value that needs to be added to the
'quantity, if the old value was bigger then it will be negative
'which is what we want
Else
'if there was no old value, then all the really need to do is get the
'new value as the change
intChange = Quantity.Value
End If

'ok, now we create our SQL statement.
strSQL = "UPDATE Products " & _
"SET Products.UnitsOnOrder = UnitsOnOrder + " & intChange & _
"WHERE Products.ProductID = " & ProductID.Value '<- or whatever your control on the form is
'called that is bound to your productID field in
'the order details sub-form
'now we have created the SQL we need, time to run it
CurrentProject.Connection.Execute strSQL

'uncomment the next line to see the SQL that was generated
'debug.print strSQL

'that should do it for the first one, and it should give you an idea of how to carry on
End Sub


That is the code. I get an error message upon leaving the field sayin 'one of the required parameters is missing'

Any ideas?

Any help greatly appreciated. I'm way behind the rest of my I.C.T class as they have al finished their projects.

Surely somebody knows the answer

THanks in advance

Combo Box Update

Jun 20, 2005

Hi All,

I have a combo box on my form that is retrieving its list of values from a table. After I choose a value I want to write it to another table's field. I can get this to work where it is writing to the other table's field, but when I open the form to see the field of where the information is supposed to be writen to it is not refreshing. What property on the combo box should I used to ensure that the field of the other table is instaneously updated when the combo box's value is chosen.

Best Way To Update Data

Jul 13, 2005

I have 2 tables:

"LookupDates" which has

ContractYear
YearStart
YearEnd

and "Staff" which has

Name
StartDate

The tables are not linked in anyway as the LookupDates table is used for referencing.

What I want to be able to do is add another column to the staff table that shows what contract year they started in.

I have tried DLookUp but I have read that you cant use update queries with DLookup in the way that I want to...

DLookup("[ContractYear]", "LookupDates", "[StartDate] Between [YearStart] And [YearEnd]

If I create a form and cycle through the records I can get the DLookup function to work via VBA but this isn't very practical

Can anyone help with this problem?

P.S. I didn't put this post in the queries forum as I think it falls under the General section.

Thanks for any help
