1. Make transparent forms easily

VB.NET can easily make any transparent form: all we have to do is set the Opacity property to a value between 0.0 (completely transparent) and 1.0 (completely opaque) in the form's Properties window:

Dim frm As FrmTrans = New FrmTrans () frm.Opacity = 0.5 frm.ShowDialog ()

2. Easily make the form that is always at the top.

In VB6, to make a form that is always at the top, we can only resort to the troublesome API function. However, in .NET, we simply set the TopMost property of the form to achieve the same effect! For example:

Dim frm As frmTopMost = New frmTopMost () frm.TopMost = True frm.Show ()

3. VB.NET design and make forms: invisible forms

If you want to write a hidden program that will not be discovered by others, making invisible forms is a necessary step. The visibility of a form is usually controlled by the Visible property. However, if you want the main form of a Windows application not to be visible when the application starts, you will find that the method of setting its Visible property to False is invalid, and the form will always display itself (this is because the lifetime of the startup form determines the lifetime of the application). Even so, we can easily implement invisible forms by simply setting the startup of the application as a module to separate the lifetime of the application from the lifetime of the form. In the following example, the form is automatically hidden for a specific period of time:

(1) in Visual Basic, right-click the project and select add Module to add the module to the Windows application.

(2) in the added module (or class), create a Main function that can be used as the project startup object:

Dim F1 As New Form1 () f1.Visible = False While Hour (Date.Now) < 15'if the current time is earlier than 15:00, the form automatically hides Application.DoEvents () End While f1.ShowDialog () End Sub above is all the content of the article "how VB.NET makes forms".
