[SOLVED] If statement whether or not a sub has run

If statement whether or not a sub has run

I am trying to run a if statement to send an email if the sub has run and is successful.

The current code I am trying is

Private Sub SendButton_Click()

Call Populate

If Populate = True Then
    Application.ScreenUpdating = False
    Set OL = CreateObject("Outlook.Application")
    Set EmailItem = OL.CreateItem(olMailItem)
    Set Doc = ActiveDocument
    Doc.Save

    With EmailItem
        .Subject = "New ePRF Available"
        .Body = "I have completed a new e-PRF"
        .To = ""
        .Importance = olImportanceNormal
        .attachments.Add Doc.FullName
        .Send
    End With

    Application.ScreenUpdating = True

    Set Doc = Nothing
    Set OL = Nothing
    Set EmailItem = Nothing
Else
    Call Populate
End If
End Sub

This is something I have never really done before so am very confused! Any help would be grateful!

Thanks

Solution

Make Populate a function and have it return a boolean value, then check that value in SendButton_Click

I made a nonsense populate to show the general idea.

Option Explicit

Private Sub SendButton_Click()

If populate() Then 'Test the return
    Application.ScreenUpdating = False
    Set OL = CreateObject("Outlook.Application")
    Set EmailItem = OL.CreateItem(olMailItem)
    Set Doc = ActiveDocument
    Doc.Save

    With EmailItem
        .Subject = "New ePRF Available"
        .Body = "I have completed a new e-PRF"
        .To = ""
        .Importance = olImportanceNormal
        .attachments.Add Doc.FullName
        .Send
    End With

    Application.ScreenUpdating = True

    Set Doc = Nothing
    Set OL = Nothing
    Set EmailItem = Nothing
Else
    Call populate 'This is probably not what you actually want, but hard to tell without seeing populate
End If
End Sub

Function populate() As Boolean 'specify the return type
    Dim returnval As Boolean
    Dim x As Boolean
    Dim y As Boolean
    
    returnval = True 'Start with true, if anything is false below flip the value
    
    x = True
    y = False
    'just showing the flow, you would be checking your userform values here
    If Not x Then
        returnval = False
    ElseIf Not y Then
        returnval = False
    End If
    
    populate = returnval 'return the value
End Function
