Is it possible to declare a public variable in vba and assign a default value?
.NET has spoiled us :)Your declaration is not valid for VBA.
Only constants can be given a value upon application load. You declare them like so:
Public Const APOSTROPHE_KEYCODE = 222
Here's a sample declaration from one of my vba projects:
If you're looking for something where you declare a public variable and then want to initialize its value, you need to create a Workbook_Open sub and do your initialization there. Example:
Private Sub Workbook_Open() Dim iAnswer As Integer InitializeListSheetDataColumns_S HideAllMonths_S If sheetSetupInfo.Range("D6").Value = "Enter Facility Name" Then iAnswer = MsgBox("It appears you have not yet set up this workbook. Would you like to do so now?", vbYesNo) If iAnswer = vbYes Then sheetSetupInfo.Activate sheetSetupInfo.Range("D6").Select Exit Sub End If End If Application.Calculation = xlCalculationAutomatic sheetGeneralInfo.Activate Load frmInfoSheet frmInfoSheet.ShowEnd Sub
Make sure you declare the sub in the Workbook Object itself:
Just to offer you a different angle -
I find it's not a good idea to maintain public variables between function calls. Any variables you need to use should be stored in Subs and Functions and passed as parameters. Once the code is done running, you shouldn't expect the VBA Project to maintain the values of any variables.
The reason for this is that there is just a huge slew of things that can inadvertently reset the VBA Project while using the workbook. When this happens, any public variables get reset to 0.
If you need a value to be stored outside of your subs and functions, I highly recommend using a hidden worksheet with named ranges for any information that needs to persist.
Sure you know, but if its a constant then
const MyVariable as Integer = 123 otherwise your out of luck; the variable must be assigned an initial value elsewhere.
public property get myIntegerThing() as integer myIntegerThing= 123end property
In a Class module then globally create it;
public cMyStuff as new MyStuffClass
cMyStuff.myIntegerThing is available immediately.
