Passing a flag between forms

My application has a data entry form with a “RETURN” command button that unloads the form and returns the user to the main “dashboard”.

Before those actions are allowed to execute, the data is sanity checked. I do this by showing a form frmSanityCheck that performs five sanity checks and displays the results on-screen. I have a public boolean variable bSanity that is set to “True” if the data passes the sanity checks, “False” otherwise.

Data Entry Form;

Sub cmdReturn_Click()
frmSanityCheck.Show
If bSanity = True Then
Unload Me
End If
End Sub

Open in new window


Sanity Check Form:

Sub Form_Load()
	bSanity = True
‘---
‘--- do the checks
‘--- possibly setting bSanity = False
‘---
End Sub

Sub cmdReturn_Click
‘ Returns to Data Entry Form
Unload Me
End Sub

Open in new window


Question: How does the cmdReturn sub in the Entry Form know to wait for frmSanityCheck to unload before checking the value of bSanity?

Is there a better way to do this?

If you when you load frmSanityCheck you load it modally with frmSanityCheck.Show vbModal, nothing can be done until that form is unloaded.
