i built a small app in vb.net and i would like my icon to appear next to the computer clock in the taskbar. how can i do this?
You should add a NotifyIcon component to your form. Assign an icon to its Icon property, and set its Visible property to true, and it should appear next to the clock. You can use the various mouse events of the component to let the user interact with it, or you can assign a context menu to it.

How can I force a tooltip to stay open or at least increase the duration in winui3?
Most examples I found are either for wpf or uwp and none of seems to work.
I am afraid there is no property that lets you keep the ToolTip visible for more than a short period of time in UWP or WinUI 3.
What you can do is to replace the ToolTip with a Popup and control its visibility programmatically by setting the IsOpen property.
I am trying to create an application that will start up over the Windows' taskbar on the bottom left corner. I want the form to overlap the taskbar. All my methods ends on making the form load above the taskbar.
You can set the form's property TopMost to true to achieve that
Is there any property of pop up , wherein we can dim the window app.
As in metro app there is no Child Window control available , so using
popup in place of it but the problem in popup is when it is open the
user can still interact with other control on window app.
So is there an workaround to make the window app dim when pop is open.
I'm not sure to understand what your trying to do. You can put a Border as first child of the popup which exposes the Background property. So if you specify a not null Background (Transparent for instance) the popup will catch every interactions.
It sounds like you want the MessageDialog class. The popup is meant to be non-modal, letting the user close it by just clicking away from it. The MessageDialog is a regular modal popup that does not let the user interact with the rest of the app when it is displayed.
If you really insist on using the popup control, here is a simple workaround:
Make the popup use all the screen (using a grid or border), then set that background to Black with opacity 0.1 (or any other color you see fit, this is to give a "dim" effect), then inside this popup, place another container with the size and margins that you want to act as your "real" popup.
Because the popup takes the whole screen it will prevent the user from clicking anywhere in the screen.
Image shows the buttons on my UI in vb.net
All these buttons are having background images. Now what i want is these buttons be shown as inactive when actions corresponding to them are not available so I am making them cmd.enable = false but still on UI there is no visual effect of this disabling them on these buttons. They keep looking same as in enabled mode. So how to give effect of disabled state to these buttons.
In the same way i want effect to be visible when mouse is hovered over these buttons and buttons are clicked
They don't look like buttons at all, it looks like a row of images. Use a real Button or a ToolStrip with ToolStripButtons, set their Image property. When you set their Enabled property to false then they automatically remove all color from the image, making it look disabled.
I have a button and inside my button I have an image control. When the users click on the image I'd like to animate the button so it appears the button was pressed. I don't really care whether the actual button press event fires or not--it's the illusion of a button press I want to see.
Note: the only options I see on the web involve writing directly to the Windows API--a level of complexity and non-upgradability I really don't want to get into.
Why not just use two different images, one for a normal state, and another for when your button is being pressed.
If you want to go for more complicated route try using GDI+. Here is a quick sample tutorial on how to do this.
Why are you using an image control inside your button control instead of using the button control's Image property?
Using the Image property of the button will give you a button with an image that the user can press and that will raise the OnClick event without doing any extra work or re-implementing features that are already available.
I ended up making my picturbox look like a button by giving it a raised border style. Then on the mouseclick event I simulate the look of a button press by changing the border style for a few hundred miliseconds.
Private Sub simulateButtonPress(ByRef pictureBox As Infragistics.Win.UltraWinEditors.UltraPictureBox)
pictureBox.BorderStyle = Infragistics.Win.UIElementBorderStyle.Inset
Application.DoEvents()
System.Threading.Thread.Sleep(400)
pictureBox.BorderStyle = Infragistics.Win.UIElementBorderStyle.Raised
Application.DoEvents()
End Sub
