Forms :: IF Statement To Test Null Values In 2 Different Forms
Jun 12, 2015
I have a main form with many subforms. Each subform has couple of ComboBoxes or/and TextBoxes. I want to make sure that end users dont miss completing any of required values. For example, in the subform (Clients), an end user is supposed to put either "Male" or "Female" in the (Gender) ComboBox. In another subform (Job Info), the end user will put info of the job like Wage, Employer, Date of Job Start... ete.
What I want is to get VB IF statement which tests if the textboxes "Wage", "Employer", and "Date of Job Start" in the subform (Job Info) are not null, then the CobmoBox "Gender" in the subform (Clients) should not be null too, with a warning message to complete the missing value.
A form with a text box expecting a date has the validation property as, >#1/1/2010# And Is Not Null. If a date is entered older that this the error is caught however if the field is left null it is not caught as an error. I have tried several modifications of this statement with the same results.
I have a form in my Access database that has 3 input boxes by which a user can locate a record by. The problem I am running into is that I can not get a nested IF statement to work properly to first check which of the search boxes are filled in and second search by whichever is filled in. I have come up with the following code that seems to be only searching by the first input box. If the first input box is blank it does not move to the second or third numbers so I imagine there may be something wrong with the order of my IF statement or the syntax is off.
Im trying to sort a form on a date. it only has dates put in once a confirmed date is known so when i sort all the blanks come to the top is there a way of sorting excluding null values
I have a search form that has 8 criteria fields, of which the user can fill (from combo boxes and txt boxes) any number of them to narrow or widen the search.This by the way works perfectly. What I want to have is a message box pop up if the user does not enter any criteria and click search.
I tried stringing multiple if isnull statements together but realised that because I have an onload function that sets all fields to "" the isnull function won't work, so have changed this to the Len function.But when I run it, it just skips straight past the len line and opens the search detail form regardless. I suspect I have the order of things wrong, as it does not throw up any errors when run.
I have a form that has a combobox with table names in it. I want to execute a very complicated SQL statement but I want to put the table name (from the combobox) into the SQL statement. I'm planning on making a button to do this, but I don't know how to put the SQL statement in VBS which would use the combobox value as the table name in the SQL statement.
I have a multi-select listbox (called PotentialItems) which behaves perfectly unless one of the fields has a null value in it, in which case I get an error 13, "Type mismatch" in the following code. It is valid business-wise for column 9 to be null.
Code: Dim varItem As Variant Dim dblTargetPrice As Double With Me.PotentialItems For Each varItem In .ItemsSelected If Not IsNull(varItem) Then dblTargetPrice = Nz(.Column(9, varItem), 0) '<----- Error here End If Next End With
I am having an issue with the sort order on a subform.
Basically I have a main form with Client Details and a subform hich displays the associated test results for this client. Each client can have multiple test results which should be displayed in date order.
Initially the form was based on the table 'TestResults' and I set up the form with the Orderby property set to the field 'TestDate' and OrderByOnLoad set to True. This didn't work and the records were displayed in random order.
Next I tried setting up the form based on an SQL query with the field 'TestDate' sorted in Ascending order - same result. Tried this with OrderBy and OrderByOnLoad both set/unset as a pair and individually - always the same result.
How can I get the subform to display the test results in date order?
I am trying to allow a calendar to search through a text box with a large amount of data in which will have headings using the date so i wanted to use a calendar search. Hopefully this will be be like the find function in word where you type (or in this case select a date) then click search or next which will take you to that specific date.
my issue is i have multilble text box in my form & based on change in one of this text box i need the code to compare between data in the form & table & returm Msg if it is not matching. attached screen FYI.
i look in the internet but i could not figuer out the VBA code since i do not know VBA. what comes to my mind to to use select case.
It might be an easy one but I just wasted the past hour deciphering through my code in order to solve the run-time error '94' that I'm getting when trying to execute the following code:
Code: Private Sub cmdUpdateDates_Click() '################################### 'This sub aims at combining the timesheet date and the start and end time into the fields [Start Time] and [End Time]. '################################### Dim intCounter As Integer intCounter = 0 Dim rs As ADODB.Recordset
I need to pull the calculated values from approximately 10 forms into another form. This is a summary form that should have all the totals pulled from the other forms.e.g. Form A has a textbox that reflects the sum of the amount. This is the total balance of form A.Form B, Form C, etc. all have a total Balance.Now, i need to pull all these totals into a summary form
-Form A Total Balance: x -Form B Total balance: y, and so forth.
How and what is the best method to approach?I have tried using Forms![Formname]![Total] to get the data. This necessitates the need to hide all these forms and I ended up with blank forms, etc.Even so, the total sometimes appear and sometimes it does not. so it is very unstable.
In Access 2010 I have a Data Entry Form on which I have an unbound textbox in the header that the user can put a default date in. In the body of the form is a bound textbox that records the date and the default value is set as =defaultdatestat (obviously the name of the box in the header).
Problem: The default date shows up perfectly until a value is put in any of the other text boxes.
For further info : If you put values in text boxes default value disappears; if you then push escape the default value reappears when the values in the text boxes disappear.
I have several result fields which are all drop down lists. I want each result field's drop down list values to be different depending on the selected value of the Test1 drop down list.I came up with using the .rowsource keyword. My syntax seems to be fine but I'm not getting any values under the result fields when I run the form.Here is my code so far:
Private Sub Test1_AfterUpdate() If Me.Test1 = "Stress Echo" Or Me.Test1 = "Stress SPECT" Or Me.Test1 = "Stress PET" Or Me.Test1 = "Stress MRI" Then Me.Test1Result2.RowSourceType = "Value List" Me.Test1Result3.RowSourceType = "Value List"
I have a query where data is first sorted by user input; first field's criteria: [fieldname], then by another field's criteria: Is Null.
I know there are records containing null values in the second field, as I have run a select query with the criteria: Like "*", to make sure they are null, and not zero-length-strings.
I am trying to using an iif statement to pick up null values, but I don't know what to type in the function. I tried using "is null", but got an invalid message.
What value I should type in to get null value in the function below?
After hours of playing around i finally have my IIF statement working the proplem is now is that when the Value is null it gives a blank value on my Report. How do i get it to show the value of 0 when it is Null. can i use an isNull withen my IIf statement maybe nested what is best practice?
In Access 2010, Under what conditions can we read values from forms?
I'm trying to write query in which i want to find and update records based on saved record, but seems like Access is not reading values. I've opened the form and add a button to run a query, so the form is for sure in focus.
On the other hand, when I try to read values from form based on new record, a record which is not yet saved, Access is reading values without any problem.
Can't figure out the syntax for specifying a null value for a text or combo box when filtering a table via a form. "Is Null" seems to work for query criteria but doesn't work for form controls. If one right-clicks on a form control displaying a null value, one of the choices is "Equals Blank" which if selected works fine but what does one use for the text filter if the record for the control in question does is not displaying a null value?
i make the database for the fast food place , i have problem with the listbox , in the main form when opening you see all the tables of the restaurant for right know i active table 1 and table 2 , when click on the table it should be display all the item but the problem when i click on the table say "invalid use of null" i don't no what is problem.
I've built a form on my Access database that invites a user to enter a start date and an end date into two textboxes. When i press a command button, a parameter query runs which uses the two textboxes as the parameter's criteria. However, to ensure that both textboxes have a data entry, i have tried entering in some VBA that prompts the user to enter in a date if its left null...then set focus to that textbox: Here it is...
If IsNull(Me.txtWeight1) Then MsgBox "You must enter a minimum weight!" Me.txtWeight1.SetFocus Else If IsNull(Me.txtWeight2) Then MsgBox "You must enter a maximum weight!" Me.txtWeight2.SetFocus Else If IsNull(Me.txtWeight1) And IsNull(Me.txtWeight2) Then MsgBox "You must enter a min and max weight!" End If
This will not compile for me! I've tried with and End If and without an End If and other stuff. Why won't it work?
User pick a record from a list and are able to doubleclick that record which will open another form with that record's ID. If the field is Null, then another form opens allowing the user to create a new record. The part that doesn't work, is if that record that was in the combo, gets deleted from somewhere else. Then the ID is still being shown in the combo (that's OK but it's no longer null), so double clicking the field does not bring up the correct Create New record form.
What I would like to have is something similar to the NotInList message that states something like, "That record has been deleted". This is what I have so far,If not in list
Code:
Private Sub APID_NotInList(NewData As String, Response As Integer) MsgBox "Please select an ... or double-click this field to add a new entry to the list." Response = acDataErrContinue APID = Null End Sub
On double clicking the combo
Code: Private Sub APID_DblClick(Cancel As Integer) Dim stDocName As String Dim stLinkCriteria As String
