Is it possible to filter a forms records by using a boolean True/False field.
I want to show all current records for option 1, Expired records for option 2, and all records for option 3. The form is based on 'tblMembers' which has a field [Expired] which is a boolean yes/no field formatted to true/false.
I'm really not sure how to go about this. I'm creating a course booking system and when creating a booking I need to check for current bookings with the same employee and course id's (i.e. the employee is already booked on the course). The query takes the employee and course id's from a form, and is initialised when the 'book' button is pressed. It correctly selects if the person is already booked on the course but I want the query to return a value to the form i.e. if it returns null/false then the booking can be created but if it returns a record/true then the booking already exists and a message box can be displayed.
I'm not sure if I'm going about this the right way, can anyone suggest how this can be done as described above or suggest a better way of doing the task?
On my form ECOs
When my text box RELNUM is > 0 I want form properties AllowEdits set to FALSE.
When RELNUM is null I want form properties AllowEdits set to TRUE.
This must be possible, but not entirely sure where to start.
Since I can scroll through records in this form I'm thinking I have to put an event in ON LOAD, bbut beyond that I'm at a lost.
I have a query that shows banned users (I work in a school). When a student's ban has ended, a tick box is checked in a form linked to tblBannedUsers to show they are no longer banned.
The query itself simply queries all records in tblBannedUsers with a username field (UserID) taking search criteria from a box on a form.
However, I want to filter out the students that are no longer banned (those with a tick in the checkbox). To do this, I thought it would be a simple case of editing the query, and in the Ban Lifted field criteria, use =False to say I only want those records with a tick.
This doesn't work and I still get all records given the combo box filter (which are just filtering for a username...if I leave it blank it gives all records via Is Null).
What should I be putting in the criteria to filter out those records with a ticked checkbox?
Thanks,
Steve Swallow
EDIT: I've just done a test query and <B>No</B> is the criteria to use, but when I use this criteria in my query which also take data from a form's combo box it ignore the <B>No</No> criteria.
There are around 100,000 records to update. Would a SQL Statement be more efficient?
It is a local table being used to sum up the results of a handful of rules.
The columns can only hold True or False (datatype)
If and only if all columns are True - then true
MyRow T T T T T T T T T T - Sum in next column is T
MyRow T T T T T T F T T T - Sum in next column is F
Speed is very important. The Recordset for a single row is still open on the Currrent Record since the Update just finished.
Code:
RS_RE_1SegStatusProfiled.Fields("Total") = (RS_RE_1SegStatusProfiled.Fields("RE_1") AND CStr(RS_RE_1SegStatusProfiled.Fields("RE_2") AND (RS_RE_1SegStatusProfiled.Fields("RE_3") ' and so on
My guess is that since the recordset is open to the current record on a local table, it will be efficient to just re-read all of the values and And them together.
Since I have code writing to each record, I could also go through all the extra assignment of a local variable.
I'm trying to limit the records on a subform via an option group selection. The group has 2 options: optionTrue (option value = 1) and optionFalse (optio value = 2). I have the following code in my query criteria of the true/false field.
IIf([Forms]![FrmHome]![frameProcessed]=1,-1,0)
The false part works, but the true part doesn't. I've tried many variations using true/false, using checkboxes, etc. and nothing works.
The database is SQL Server if that matters.
Any suggestions?
Also, is their a way to have an option for True or False or ALL?
Thanks,

I have a form that shows the records found in a query if the completed tick box is false. this is fine, but i have also put the tick box on the form, and wish the user to tick it when they are done how ever they, get a beeping error and wont let you change it to true. Can anyone suggest the resolutoin for this.
View 2 Replies View RelatedI want to create an opion group with two rad buttons in it. The values of those button wont be values but as true or false in order to use it in another text box to performa calculations. EX.
=IIf([radNew],"Hello",IIf([radUsed],IIf([txtAgeofCar]<184,[txtExciseinTotal]=Null,IIf([txtAgeofCar] Between 185 And 365,[txtExciseinTotal]*(-0.15),IIf([txtAgeofCar] Between 366 And 1095,[txtExciseinTotal]*(-0.2),IIf([txtAgeofCar] Between 1096 And 1825,[txtExciseinTotal]*(0),IIf([txtAgeofCar]>1825,[txtExciseinTotal]*(0.25))))))))
As you can see radNew and radUsed are the Options Buttons. Its not working in an option group.
Thanks in advance
Hi all,
My client has an Access database where the value of a checkbox is stored in a field called Exclude_PropCount as -1 or 0. I am trying to get this form working online, but have been unable to successfully store this value in the db. I have set up a simple page to test it, and my relevant code is this:
sql_save = "INSERT INTO HVM_Data (VC, Exclude_PropCount) VALUES ('a9', '-1')"
con.Execute sql_save
set duplicateVC1 = db.Execute("SELECT Exclude_PropCount FROM HVM_Data WHERE VC = 'a9'")
response.write duplicateVC1("Exclude_PropCount")
But no matter whether I have '-1' or '0' in the INSERT statement, the response.write line always returns "False". And of course I've tried inserting "true" and "false", but it only accepts an integer.
As exceptionally bad timing would have it, my server is slightly fubar and I can't download the database to my PC to see what's actually being stored there, but looking at the above code, do you see anything I'm doing inherently *wrong*? This is my first time with checkboxes so I won't be surprised if that's the case. Hints?
Thanks!
Using DoCmd.TransferSpreadsheet I'm exporting a table which has a couple of Yes/No fields formatted as Yes/No. However when I export, they appear as TRUE/FALSE? Am I doing something wrong?
View 3 Replies View RelatedI've built an IFF expression that is determined by a number of variables.
If any of the Data fields are filled I want the statement to return true.
If NONE of the four are filled in I want it to return false.
As it is, it returns true no matter what.
Here is the expression I'm using:
Title: IIF (IsNull([Data1] and [Data2] and [Data3] and [Data4]), True , False)
I am trying to create a query pulling from several tables. I will use the example below to illustrate what I'd like to do.
I have a field called 'Acc_Num', one called 'Stat_Code', and a third called 'Cat_Code'.
Each 'Acc_Num' can have multiple records because there are multiple Stat_Code and Cat_Code values.
What I want to do is isolate just the Acc_Num records where Stat_Code = 1 and Cat_Code equals A1.
I also want to isolate the Acc_num records where the Stat_code = 1 and where Cat_code does not exist.
Can make a column show true or false in a table when two other columns in the table match each other? I think the statement would be like this:
If([Column1] = [Column2], True, False)
The only problem I am having is that I don't know if it can work in a table or does it just have to be in a query?
In a form, the value of any field may determine if the other field will be true or false. For example in my form, inventory, if value in code is equal to 2 then the Field Table will be automatically false.
View 12 Replies View RelatedI have a report where my customer wants to be able to input a value and then be able to select whether the report shows values above or below that value. I have a combo box that has 2 values (1=Less than or equal to, 2=greater than or equal to). There is a text box where he inputs the rate to compare against (e.g. $75). When he hits submit, the application stores the values of the combo box and text box into global variable and then I have a public function that can be used to retrieve the values. GetHRate() gets the value to compare against and GetHRateCompare() gets the value to indicate <=(1) or >=(2).
In my query for criteria for rate I have this expression:
IIf(GetHRateCompare()=1,"'<=",">=") & GetHrate()
I've tried every combination of double quotes, single quotes, no quotes moving the GetHRate inside the IIf statement and nothing seems to work.
If I just hardcode <=GetHrate() into the criteria it works perfect but that does not achieve my goal of letting him select over/under at run time. Here's the full query:
SELECT qryCustomers_AverageTimeByScheduleID.ServiceName, qryCustomers_AverageTimeByScheduleID.ScheduleID, qryCustomers_AverageTimeByScheduleID.SumOfTotalTim e, qryCustomers_AverageTimeByScheduleID.PropertyID, qryCustomers_AverageTimeByScheduleID.PropertyName, qryCustomers_AverageTimeByScheduleID.MonthCount, qryCustomers_AverageTimeByScheduleID.AverageTime,
[Code] ....
My first question is how do I append 00001 so I can have a value for the false side of 9123400001 instead of 912341...My second question is why does it prompt me to enter parameters? It also produces all false values from the if statement...What I am trying to do is use a column that has either a Y or a N and using the if statement to correspond with different formulas depending on the Y or N.This what I have so far.
SELECT
IIF (ISRAILROAD=Y,9 & UCN & TXRTAREA, 9 & UCN & 00001 )
FROM CombinedUtility;
In access report, I'm trying to change color of text in specific records based on the true/false value in another record. Works in forms using conditional formatting, but won't seem to work in a report.
Here's what works in forms : IIf([2009 Symposium]=true, forecolor=255 ....this changes the records to red.
But using the same expression in a report doesn't change the text color.
I have a simple split form with datasheet on the bottom and a couple of comboboxes (unbound) on the form header which the user can use for filtering the data. When some users open the form the allowedit property of the form is set to false, because those users can only view the records. But the result is that also the comboboxes cannot be set, hence no filtering!
View 6 Replies View RelatedI have created my tables and form and am now trying to run reports to organize the data. I have figured out how to group the individuals by group and treatment, but can't figure out how exclude individuals from the final list if they are already in another. As background, some of the individuals are eventually excluded from the experiment, though I keep the initial data. When the exclude individual checkbox is checked ("True" on the report) I do not want the individual to be listed in the "False" list, even though there are entries for that individual when that checkbox wasn't checked (when it was "True"). This is so I can get an idea of the current totals in each group.
Implant Period
>Treatment
>>Exclude individual?
>>>Individual ID
I feel like this should be a fairly simple task, but I cannot figure it out... Maybe there is coding to exclude individuals from the "False" list if they are already listed in the "True" list?
Hi
I have a subform with several records entered. When a particular entry is made in the subform
eg. chocolatebiscuit
I want the subform to not allow any more entries - records in that particular subform
Is there a easy way to do this?
I have tried to do this by saying
Me.Form.allowadditions = false
Unfortunately this works on the whole form
and stops the next subform - belonging to the next main record
from adding a new record.
How do I restrict the new records in A particular subform?
I tried
Me.Form.allowadditions = true
on entering the subform
but it doesnt work every time.
Also i put on enter
if not chocolatebiscuit then
allow entries
but for new records it takes the last entry in the subform
which could be two records back in the main form
says yes there is a chocolatebiscuit
and will not allow a new record.
This seems really straight forward to me. I have 3 forms - FormA, FormB and FormC. When I open FormA the user inputs some information, when they tab to the last field, FormB opens (which I want to be invisible) and Form C opens.
I've tried putting this coding on the Open event of FormB:
Me.Visible = False
I've also tried putting this code on the Open event of FormC
Forms!FormB.Visible= False
Neither work. My form (FormB) still displays when eithr event occurs.
Any suggestions?

Hi,
I have Add button. When i click on the button, it will open frmstaff for me to enter new staff record. Now, i have to set DataEntry=True. It means i have 2 forms, one for data entry and another form to view previous staff records. Is it possible for me to do like this?
Private Sub cmdAdd_Click()
Set Forms("frmstaff").DataEntry = True
End Sub
but it will give me error,
Invalid use of property.
any idea? thanx in advance..;)
How can I create a "Filter Button" on a form and filter my records? I create a textbox on a form and a filter button on the right. Then I click the filter futton, the filter function will search/match the content in the box through the datasheet. And then the results of the filtering will be pop up on the split form datasheet.
View 3 Replies View RelatedI have placed a filter button on a form as a filter and written the following on-click event procedure:
DoCmd.SetWarnings False
DoCmd.RunCommand acCmdApplyFilterSort
Me.Filter = "ACCOUNT_DO_NOT_EMAIL = 'HS'"
Me.FilterOn = True
When I click the filter button I get a blank message box titled 'Microsoft Access" and an OK button, when closed the filter works perfectly.I have checked this procedure in other forms and it works without showing the blank message box.The only difference with this form is that its control source is a union query.
I'm calling this code on my Form's BeforeUpdate Event which I understand should only run if the form is dirty. In this example, the code should check to see if 4 fields ("txtField1", "txtField2", txtField3", "txtField4") have data present, if not highlight them yellow.
Function Msg()
Dim ctl As Control
Dim strFields As String
Dim strControl As String
Dim intCounter As Integer
Dim blnEmpty As Boolean
For Each ctl In Me.Controls
blnEmpty = False
If ctl.ControlType = acComboBox Or acTextBox Then
If ctl.Visible And Len(ctl.Tag) > 0 Then
Select Case ctl.Tag
Case "txtField1", "txtField2", txtField3", "txtField4"
If IsNull(ctl.Value) Then
blnEmpty = True
ctl.BackColor = vbYellow
Else
ctl.BackColor = vbWhite
End If
Case Else
If ctl.Value = 0 Then
blnEmpty = True
ctl.BackColor = vbYellow
Else
ctl.BackColor = vbWhite
End If
End Select
If blnEmpty Then _
strFields = strFields & ctl.Tag & vbCrLf
If blnEmpty Then _
If Len(strControl) = 0 Then _
strControl = ctl.Name
End If
End If
Next
If Len(strFields) > 0 Then
Cancel = True
MsgBox "You have not completed all data fields, " & _
"please enter data in the following fields:" & vbCrLf & strFields, _
vbExclamation, Me.Caption
Me(strControl).SetFocus
Me(strControl).BackColor = vbWhite
Exit Function
End If
End Function
However, it keeps falling over at:
Cancel = True saying "Compile Error: Variable Not Defined"
I want to be able to run this code from a "Close Form button" to ensure that either the record is not created unless the fields listed are filled in or the form closure is cancelled so that the user can complete the missing data.
I've seen varients of this code on a couple of Access forums but can't find a solution for the "Cancel = True" issue.
Am I doing something wrong?
i have a little problem, at least, i think it is little.
Within my access db form i have made a combobox for searching a number. When selected the applicable information will be shown in the detail part of the form.
I made a button in the detail section, to allow people to change the information.
However, after i placed the button with the allowedits = false and true part to autorise if people may or may not change the information, the combobox for searching a number only works when i first press the button [change] (so that the property is set on allowedits = true), then search the number by the combobox. Directly after that the combobox is not allowed to be used(!?)
What do i want?
- combobox is allowed to be used always
- information in detail section only is allowed to be changed when pressing the [change] button.
I am not sure how to do this, please help me if you want? :confused:
