Hello,

I have an icon that I want to display in the taskbar; however, I don't want this icon to display in the title bar. I tried setting ShowIcon to false, but that hides my icon in both the title bar and the task bar. Is there any way to only hide it in the title bar?
i am using vb.net 2015 desktop

your existing setting should be correct >> ShowIcon to false

then try go to project properties and change the icon there accordingly?

Try making different sized (32x32 and 16x16) icons for the app.  The smaller one (title bar?) being blank.

I get both sizes created automatically when I add an icon to the project:

Odd.  I don't have VS 2015 to test but there ought to be a way to customise the icon for the app.

In the form load event
        Me.Icon = My.Resources.Icon1
where Icon1 is the name of your custom icon.

You didn't read my suggestion properly (or your PC behaves differently than mine).

Try making different sized (32x32 and 16x16) icons for the app.  The smaller one (title bar?) being blank.

So to brief it ; Andy need to have two icons with same name.My question is how does the vb.net app know which icon to use for titlebar and taskbar.Cannot see any settings for doing that.

The system chooses the icon automatically based on how big the icon is and how big is the icon to be displayed.  The title bar being much smaller than the task bar means (in general) the 16x16 icon will be used for the title bar and the 32x32 will be used for the task bar.

ShowIcon and ShowInTaskbar are properties of the form, not the project.Capture.JPGSetting ShowIcon to false instructs the form not to display the icon on the caption (or title) bar.  Setting ShowInTaskbar instructs the form not to display on the Windows taskbar.

Well one way is by setting the FormBorderStyle to either FixedToolWindow or SizableToolWindow; e.g. -Capture.JPGThe problem with this is that it results in a more or less border-less form with no control box (Minimize, Maximize and Help are removed).

The next course of action is to use the API without changing the FormBorderStyle; e.g. -
Imports System.Runtime.InteropServices

Public Class Form1
	Const WM_SETICON = &H80
	Const ICON_SMALL = 0

	Private Sub OnLoad(sender As Object, e As EventArgs) Handles MyBase.Load
		Using emptyImage As Bitmap = New Bitmap(1, 1)
			SendMessage(Handle, WM_SETICON, ICON_SMALL, emptyImage.GetHicon())
		End Using
	End Sub

	<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Auto)> _
	Private Shared Function SendMessage(ByVal hWnd As IntPtr, ByVal Msg As UInteger, ByVal wParam As IntPtr, ByVal lParam As IntPtr) As IntPtr
	End Function
End Class

Open in new window

Capture.JPGThis way you still get your control box, but you end up with blank space in front of the title where the icon would normally reside (because the icon is still there it's just a 16x16 blank space).

If you look very carefully the code from it_saige  (for setting an icon) is just doing what I suggested in a more indirect way.  (It can be useful for you if you needed to make other windows API calls)

Is there a problem with what I suggested?  Here it will work in the fashion you described with one line of code.
