Declaring global Boolean variable?

[imso]

Sorry if this might be a amateur question that i'm asking.. May i ask you guys how should i actually declare global Boolean variable and fixing it to false? Or by default Excel VBA already gave it a false value? But to be safe i wanted to know how to declare and fix a value for global Boolean?

I tired this but it kept giving me error?

Public CheckBoolean1 As Boolean
Public CheckBoolean2 As Boolean

CheckBoolean1 = False
CheckBoolean2 = False

Set your values in a Module's Sub.

So i can't preset my global Boolean values initially? Or is the initial Boolean vlue set to false?

Yes, a Boolean is initialized as False. You can check this by stepping through the code, or just making yourself a simple temp sub to learn, like:

In a Standard Module:
Option Explicit

Public CheckBoolean1 As Boolean
Public CheckBoolean2 As Boolean

Sub exa()
MsgBox CheckBoolean1
MsgBox CheckBoolean2
End Sub

Hope that helps,

You could always set the variable on the Workbook_Open event if you want to initialise it as True.

Most likely, you will want to set the defaults on open as xld said. There is no need to do that though if False is what you need.

In a Module paste:
Option Explicit

Public CheckBoolean1 As Boolean
Public CheckBoolean2 As Boolean

Sub SetDefaults()
CheckBoolean1 = False
CheckBoolean2 = False
End Sub
In the VBE, doubleclick ThisWorkbook object in the Project Explorer and paste. If it is not shown, select View > Property Explorer.
Private Sub Workbook_Open()
SetDefaults
End Sub
Of course you can run SetDefaults from any routine.

I would explicitly set, even for False. Relying on system behaviour is dangerous IMO.

Hi Guys,

Thanks for your advice but do you guys happen to know is there a function which will auto initialize upon opening the workbook? So that i can set certain value at the beginning?

Yes, Workbook_OPen. I mentioned that earlier, Kenneth gave you an example.

Oh I've missed that because i do not know what Kenneth gave me was what i am mentioning above. Thanks Guys :)
