Check for null in form control

[CRDF]

Hi.
I’m doing a routine where dates are extracted from Date Controls to compose a filter.
How to check for null in the controls avoiding (of course) the Exception?

Thanks in advance!

Haven’t tested, but isn’t there property text for data controls? So
IF oDFS.Text <> "" THEN ds = oDFS.Date
would help.

[CRDF]

	If oDFS.Text = "" Or oDFE.Text = "" Then
		MsgBox "Dates for the Period missing!"
		Exit Sub
	EndIf

Thank you!

Also we can use IsEmpty method.

Ok, thanks.
As they’re controls with date picker it would make no sense to insert no valid dates.
Learned about the Date property to compose a filter for a subform and didn’t think about possible Text one.

Forgotten about Basic after several years!

This is a method from the interface XDateField, the “namesake” of the Basic function.
