How to simply display a control inside the StatusBar of your program.


It is not possible to directly put a ProgressBar or a button in a StatusBar in VB.NET. Solutions are available for C++ or VB 5 or 6.0. This is a way to do it in VB.NET. The previous version of this article, called StatusProgressBar only allowed using a ProgressBar. This new version extends the technique to any control.

Using the code

First, create a form with a StatusBar and a ProgressBar or any kind of control (tested with a button) you will put anywhere. You have to create at least a Panel in the StatusBar and make the Panels visible (.showpanels = True). The control put into the status bar will be called "child control".

Create an instance of StatusBarChild:

sbcProgressBar = New StatusBarChild(ProgressBar1, StatusBar1, 1)

The parameters are the ProgressBar (ProgressBar1), the StatusBar (StatusBar1) and the number of the statuspanel (0 for the first one on the left). An optional parameter is the margin between the statuspanel's edges and the ProgressBar. The ProgressBar is moved to the StatusBar when you create the StatusBarChild. You may put a button in the StatusBar the same way:

sbcButton= New StatusBarChild(Button1, StatusBar1, 1)

The StatusBarChild object's properties are the child control (.ChildObject), the StatusBar (.StatusBar), the panel number (.Panel) and the margin (.Margin). Its only method is .Resize, you should call it when the parent form is resized. See the demo for details.

How it works

The child control is declared as an object:

Public ChildControl As Control

The child control's parent is first changed:

ChildControl.Parent = StatusBar

Then, it must be displayed in the proper panel. Since there is no property to get the Panel's actual width, an API call is necessary. SendMessage returns a RECT value containing the coordinates of the Panel.

Private Structure RECT
  Friend Left As Int32
  Friend Top As Int32
  Friend Right As Int32
  Friend Bottom As Int32
End Structure
Dim Rectangle As RECT
' Use the API to get the panel's display rectangle
SendMessage(StatusBar.Handle.ToInt32, SB_GETRECT, Panel, Rectangle)
' Resize
With ProgressBar
  .Left = Rectangle.Left + Margin
  .Top = Rectangle.Top + Margin
  .Height = Rectangle.Bottom - Rectangle.Top - 2 * Margin
  .Width = Rectangle.Right - Rectangle.Left - 2 * Margin
End With

You may use this technique to put any kind of control into a StatusBar, provided it has a .parent property.

The demo uses a button in the first panel, and a ProgressBar in the second one. Click the button to make the bar progress.
