Reset a text field to NULL with VBA code
Thank you for taking the time to report an issue.
What's wrong... Please write below.
I need to convert that field to a date/time one. Which is being hindered by these values of NULL.
The problem is that when I put the word NULL in the field criteria spot, Access believes that I am referring to a value of 'null' and will not do the update.
I have done "NULL", NULL, =NULL, ="NULL", is NULL. and no success.
Please remember that the actual value is not 'null'. It is a text field that has the word NULL in the field.
I am struggling with referring to my combo boxes on the main form.
Dim strcboBox1 As String
Dim strcboBox2 As String
Dim ReSet As Recordset
strcboBox1 = frmRsales!byComboBox!Text
strcboBox2 = eyComboBox.Text
If strcboBox1 == "1993" And strcboBox2 == "1993" Then _
Set ReSet = CurrentDb.OpenRecordset("1993_All_Quarters")
Do Until ReSet.EOF
How would I pass the combo box content to a string variable
Second problem is that on the same form, I have a subform. The Reset button is in the header section of the main form. By clicking this button, I would also like the subform to be reset. The reset button includes code for the subform to reset, but it also has the same problem error. There are required fields on it. How can I reset a form and provide the primary key fields and the required key fields Null values when they can't have Null values
I set a validation rule in there. such <1000.
However, even I remove all number in text box, but I still got validation message and much enter quality number (<1000) before closed form. I set a reset button with codes as Me.SALECODE = Null and Me.Refresh
Reset button does not work. I still got validation message when I move into other text box even there are no any number in first validation text box.
I recall while developing with the DB2 database, that the DB2 driver / API supported the concept of fields having null indicator variables. That is a second variable that may be checked to find out the null state of the field in question. The correct way to deal with nullable fields on DB2 was to use that second variable, do the null check BEFORE attempting to access the variable which is suppose to contain the value of said field.
Does Access / VBA have anything comparable in ADODB.Recordset objects?
As-is, Access / VBA turns the NULL that was in that field of the record into 0 upon issuing a SQL UPDATE as the Integer variable defaults to 0.
My table in its basic form has two fields.
Field A: Client
Field B: Quantity
The data is pulled from elsewhere in the database, but when it extracts it will have the client, and quantities. but some clients will have a Null quantity. e.g. below:
1) Delete all records in an existing Table.
Now I would like to change the attributes of the IDField, so
The current Field Attributes are dbAutoIncrField. I want to reset it to dbFixedField to clear the AutoNumber Attribute
fldIDX.Attributes = dbFixedField
But it doesn't like this. Error is Invalid Operation.
I ASSUME THIS MEANS I CANNOT CHANGE THE ATTRIBUTE. OH WELL.
If anyone has any insight into how to Reset an Autonumber Field without repairing and compacting the database, I woull really enjoy seeing how you did it.
In the form we have to validate that the text filed is not null.
I have tried using this simple code :
if isNull(text0.text) then
msgbox "null values not allowed"
but then its not working. I am using it in before_update section.
which code should be used to verify that and also where should I pasting the code.
I have been trying to fix this since the last 2 days. but its not helping
Dim AnyText As String
If [Remarks TX] ="AnyText" Then
[IWC WC NM1] = Null
I probably wrote that all wrong and I apoligize, but what I need it to do is If the remarks tx field contains text then the iwc wc nm1 field should be displayed as a blank field otherwise leave it alone. It's probably a simple fix like all things in access but getting to that solution is a pain. Is this correct
