Excel – add the own function to the customized status bar in Excel

excelexcel-2010statusbarvba

If I select a number of cells in Excel, I can see some functions on those in the Customized status bar. This information is my own selection out of the following:

Average
Count
Numerical count
Minimum
Maximum
Sum

I want to add to this list a function that calculates the ratio of non-blank cells. The function would be =COUNTA(range) / (COUNTA(range) + COUNTBLANK(range)), but how can I get that into the status bar?
I don't have much experience in VBA, so some explanation would be welcome.

Try something like this (Not the best way to do it though but solves your purpose)

Explanation: What this code does is checks if the user has selected a valid range (of minimum 2 cells) and then uses the Application.Evaluate to calculate your formula and then display it in the status bar. Also note that I have not done any error handling. I am sure you will take care of it :)

Paste this in the relevant sheet code area.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    If TypeName(Target) = "Range" Then
        If Target.Cells.Count > 1 Then
            Application.StatusBar = "My Function: " & _
                                    Application.Evaluate( _
                                                          "=COUNTA(" & _
                                                           Target.Address & _
                                                           ") / (COUNTA(" & _
                                                           Target.Address & _
                                                           ") + COUNTBLANK(" & _
                                                           Target.Address & _
                                                           "))" _
                                                           )
        End If
    End If
End Sub

This is a very basic way of doing it. In case you want it applicable for all sheets then you will have to amend it accordingly.

Also the problem with this method is that it will suppress the application level messages in the status bar.

How it works

I will try my best to explain how it works - please excuse my English.

The VBE will call a system function to create the password dialog box.
If user enters the right password and click OK, this function returns 1. If user enters the wrong password or click Cancel, this function returns 0.
After the dialog box is closed, the VBE checks the returned value of the system function
if this value is 1, the VBE will "think" that the password is right, hence the locked VBA project will be opened.
The code below swaps the memory of the original function used to display the password dialog with a user defined function that will always return 1 when being called.

Using the code

Paste this code under the above code in Module1 and run it

Ios – How to change Status Bar text color in iOS

Set the UIViewControllerBasedStatusBarAppearance to YES in the .plist file.
In the viewDidLoad do a [self setNeedsStatusBarAppearanceUpdate];

Add the following method:

- (UIStatusBarStyle)preferredStatusBarStyle
{ 
    return UIStatusBarStyleLightContent; 
}

Note: This does not work for controllers inside UINavigationController, please see Tyson's comment below :)

Swift 3 - This will work controllers inside UINavigationController. Add this code inside your controller.

// Preferred status bar style lightContent to use on dark background.
// Swift 3
override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
}

Swift 5 and SwiftUI

For SwiftUI create a new swift file called HostingController.swift

import Foundation
import UIKit
import SwiftUI

class HostingController: UIHostingController<ContentView> {
    override var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent
    }
}

Then change the following lines of code in the SceneDelegate.swift

window.rootViewController = UIHostingController(rootView: ContentView())

window.rootViewController = HostingController(rootView: ContentView())
