I'm a beginner at MS Access. and I have created a local database to work on;
what I want to do is the following:
If the textBox named "Number" starts with specific digits, the ComboBox value to be automatically determined to x value.
if we can replace the Combobox with just a label that automatically updates the value based on number textbox, It'd be better, aesthetically.
I want this field to be automatically counted from another list that is being input by the user himself. Instead of individually counting each approved case, it'll pull off the approved cases BASED on a specific response code "0".
I tried this solution and it just does NOT work.
=DCount("[Response code]","Information Subform","[Response code] = '0'")
So for example, if the user inputs data as the following, this field should return with "2" automatically instead of the user counting them manually based on Response Code = 0
I want to my list to perform the following function: if selected a specific value, change the context of a textbox. It should act as a timesaver to write a specific dialog or script for the user.

New to MS Access and had a question. I am trying to add the value from txtKits and txtFG. I want them to show up in a seperate textbox called txtTotal that returns the value (the textbox also needs to non editable). Here is what the form looks like:
If the user enters just one of the two calculation fields, then I get the attached output. I want it to not give that output. It can stay blank until both are entered. Any help or suggestions?
You can check if both fields are numeric first in your calculated field:
=IIF(IsNumeric([Field1].Value) AND IsNumeric([Field2].Value); [Field1].Value + [Field2].Value; Null)
I have an Access form with a textbox bound to a currency field in a table. As expected, anything other than a numerical entry generates an error. Occasionally, users need to enter several amounts and have those added together and the result entered into the currency field.
To accomplish this, I would like users to enter an equal sign followed by a valid arithmetical string which would evaluate to a number exactly as they would in an Excel cell. For example, if a user enters "=5.31+2" I want the field to evaluate to "7.31" and use that as the value passed to the table when the record is updated or saved. The current workaround is to use the Calculator application but that isn't the ideal solution.
I tried the following code and applied it to both the BeforeUpdate and OnLostFocus events of the textbox (named "tbxTotal_Paid") but neither worked. I simply got "The value you entered is not valid for this field" error.
Dim charCt As Integer
Dim evalStr As String
If Left(tbxTotal_Paid, 1) = "=" Then
charCt = Len(tbxTotal_Paid)
evalStr = Right(tbxTotal_Paid, charCt - 1)
Me.tbxTotal_Paid = CCur(evalStr)
End If
Is this simply applying the code to the incorrect event or is this a coding issue? Any assistance is appreciated.
For me your code looks fine but you might put it in the wrong place.
Like you said Acess is giving you this error because the textbox is bound to the currency-field. So it will never accept non-numerical values because the value-checking code fires even before the before_update-event.
I think the best solution would be to hide your bound text box using Me.tbxTotal_Paid.Visible = False and creating a surrogate textbox which is not bound. You put your code in the beforeUpdate-Event or Change-Event of your surrogate. At the end you should check your final result with IsNumeric(). That way your surrogate textbox writes only correct values to your bound hidden textbox and only numbers arrive at your table.
An alternative would be to change the currency column to a string-field but this would not be wise because of potential wrong data in your database.
I am trying to set the value of a number field on a table using the value of a bound checkbox on a form. The value needs to be 40 if checked and 0 if unchecked. I'm new to this and have no idea where to start.
No, the checkbox was added to a form and is bound to a number field in the table. The data is imported from an antiquated system that uses codes that most users would not understand, so if it says 40 in the table I just want the form to show checked, all other values should show unchecked, and I want the user checking/unchecking the checkbox to update the table accordingly.
The checkbox is to indicate whether or not a customer has provided direct debit information. 40 would mean they have, anything other than 40 would mean they haven't.
One way do this is using VBA in Access. The way you access VBA console in Access, is when in your form's design view, right-click the checkbox box control and choose "Build Event" from the menu. Make sure your control's Triple State is set to "Yes" in the property for the checkbox in the form's design view. Also, be certain that the checkbox's Control Source is pointed to the field in the table where you're putting the data.
Please note that prior to doing this, it is helpful to prefix your control's name... something like chkDebitInfo... "chk" stands for check box. You can change the name in the property sheet for the control, by clicking on the Other tab, and simply change the default name, which might say something like Check625. Also, you want to set the table field's data type to an "Integer" so it holds the value.
Once you're in the VBA console, after having chosen Build Event... you're presented with the control's sub procedure. I've done a sample for you:
Private Sub chkDebitInfo_Click()
If chkDebitInfo.Value = True Then
chkDebitInfo.Value = 40 // Sets the checkbox to 40 if checked
ElseIf chkDebitInfo.Value = False Then
chkDebitInfo.Value = 0 // Sets the checkbox to 0 if un-checked
End If
End Sub
I've commented the statements that set the checkbox values if checked or un-checked, so you don't have to add those. Just substitute the control name for your's, or use the default name if you haven't changed it, and you're good. Then when the check box is checked or not checked, you'll see the values populated in the database table.
Alternatively, you can set the checkbox to default value for when the form loads, but you haven't stated it, so I won't go into it. Hope this helps. Let me know if I need to expound further.
I have an Access database that uses linked tables residing on a SQL Server. For one of these tables I created a simple form showing several fields of the underlying table.
I want to switch records using a combo box, so I added one using the Combo Box Wizard, where I selected the option "Find a record on my form based on the value I selected in my combo box".
The combo box works, but I noticed that whenever a new value is selected, Access will briefly return to the first record before displaying the selected record. I can verify this by both noticing a screen flicker (e.g., bound fields briefly display data from the first record), as well as profiling the calls to SQL Server, where I can see one query for the first record, and another query for the selected record.
This problem does not occur if I use the next/previous Navigation Buttons at the bottom of the form.
How can I avoid this unnecessary query?
What using the Wizard did was create a Macro behind the Event of your combobox click. It probably looks something like .. , , First, ="[SomeField] = " & Str(Nz(Screen.ActiveControl,0)) .. What you can actually do, instead of using the Macro, is follow something like this
If we look at what that Macro does (or what arguments it accepts), it is a little more clear on why you may be experiencing that behavior.
The first argument is Object Type then Object Name, then Record, then Offset.
Object Type - The type of object that contains the record you want
to make current. Click Table, Query, Form, Server View, Stored
Procedure, or Function in the Object Type box in the Action
Arguments section of the Macro Builder pane. Leave this argument
blank to select the active object. <- Yours would be left blank because you're referring to the combobox on the form
Object Name - The name of the object that contains the record you
want to make the current record. The Object Name box shows all
objects in the current database of the type selected by the Object
Type argument. If you leave the Object Type argument blank, leave
this argument blank also. <- Because the first was left blank
Record - The record to make the current
record. Click Previous, Next, First, Last, Go To, or New in the
Record box. The default is Next. <- This defaulted to First for me and possibly for you too, probably why you were seeing this 'odd' behavior
Offset - An integer or expression that evaluates to an integer. An
expression must be preceded by an equal sign (=). This argument
specifies the record to make the current record. You can use the
Offset argument in two ways: When the Record argument is Next or
Previous, Microsoft Office Access 2007 moves the number of records
forward or backward specified in the Offset argument. When the
Record argument is Go To, Access moves to the record with the number
equal to the Offset argument. The record number is shown in the
record number box at the bottom of the window. Note If you use
the First, Last, or New setting for the Record argument, Access
ignores the Offset argument. If you enter an Offset argument that is
too large, Access displays an error message. You can't enter
negative numbers for the Offset argument.
I wish I could give you more details, but I have not used Access in conjunction with SQL Server, so if that plays into account I would not have any insight.
I have searched everywhere for this and tried different criteria but for whatever reason the form which has a control box set to open a report which is based upon a query will not pull the data within the date range. Instead keep getting enter parameter value dialogue box.
The criteria in the query is stated as Between [Forms]![Form1].[StartDt] And [Forms]![Form1].[EndDt]
The form has two date inputs StartDt and EndDt and is pointed to open the report. Without the above criteria in the query the form opens the report and produces all the dates. So at least it allows me to enter dates and is connected to the query and report but without the criteria fails to isolate data within the required range.
When I place into the query containing the criteria (as above) under the appointment date field all im getting are two parameter value dialogue boxes one after the other displaying Forms!Form1.StartDt and the second, Forms!Form1.EndDt.
Apologies for being long winded but am desperate to solve this issue am new to access.
Thanks to everyone for any input.

It seems you have an error in your names. One of the easiest ways to check form names is to use the immediate window. Type ctrl+G and you will end up in the code window with the cursor in the Immediate window. With the form open and a date filled in, type or paste
?forms!form1!StartDt
Into the immediate window and hit return. If you get an error, it means that you have a name wrong somewhere along the line, either your form is not called Form1, and form names can be a little complicated, or your control is not called StartDt. So this is where the version of Access comes in. In Access 2010, if you type Forms! on the criteria line of a query and wait a second, it will give you a list of forms. Pick your form from the list and type ! after the name, Access will come back with a list of controls. Pick your control. You should now have the right form and control name.
