好的,根据@Visual Vincent 的建议,我在创建新表单时创建了一个构造函数。这在 frmAlert.Designer.vb 中
Partial Class frmAlert
Private mIsProcessFormCode As Boolean = True
Public Sub New()
' This call is required by the designer.
InitializeComponent()
' Add any initialization after the InitializeComponent() call.
Me.mIsProcessFormCode = True
End Sub
Public Sub New(ByVal IsProcessFormCode As Boolean)
' This call is required by the designer.
InitializeComponent()
' Add any initialization after the InitializeComponent() call.
Me.mIsProcessFormCode = IsProcessFormCode
End Sub
End Class
然后在 frmMain 我添加以下代码:
Private Sub frmMain_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Debug.Print("routine={0}", System.Reflection.MethodBase.GetCurrentMethod.Name)
Dim frm As New frmAlert(False) 'create an instance of the form without any of the Form processes
frm.Opacity = 0 'makes the form totally transparent
frm.Visible = False
frm.Show()
Dim frmWidth As Integer = frm.Width
Dim frHeight As Integer = frm.Height
Dim frCsWidth As Integer = frm.ClientSize.Width
Dim frCsHeight As Integer = frm.ClientSize.Height
frm.Close()
frm.Dispose()
Debug.Print("frmWidth={0} frHeight={1} frCsWidth={2} frCsHeight={3}", frmWidth, frHeight, frCsWidth, frCsHeight)
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Debug.Print("routine={0}", System.Reflection.MethodBase.GetCurrentMethod.Name)
'set up the alert form normally
Dim frm As New frmAlert
'show the alert form
frm.StartPosition = FormStartPosition.CenterParent
frm.Show() 'with this option the Alert Forms stay on the screen even if the Main form is minimized.
End Sub
并在 frmAlert 中添加以下代码:
Private Sub frmAlert_FormClosed(sender As Object, e As FormClosedEventArgs) Handles Me.FormClosed
Try
'process the form code ONLY if required
Debug.Print("routine={0} mIsProcessFormCode={1}", System.Reflection.MethodBase.GetCurrentMethod.Name, mIsProcessFormCode)
If mIsProcessFormCode Then
'do Closed stuff
End If
Catch ex As Exception
Debug.Print(ex.ToString)
End Try
End Sub
Private Sub frmAlert_FormClosing(sender As Object, e As FormClosingEventArgs) Handles Me.FormClosing
Try
'process the form code ONLY if required
Debug.Print("routine={0} mIsProcessFormCode={1}", System.Reflection.MethodBase.GetCurrentMethod.Name, mIsProcessFormCode)
If mIsProcessFormCode Then
'do Closing stuff
End If
Catch ex As Exception
Debug.Print(ex.ToString)
End Try
End Sub
Private Sub frmAlert_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Try
'process the form code ONLY if required
Debug.Print("routine={0} mIsProcessFormCode={1}", System.Reflection.MethodBase.GetCurrentMethod.Name, mIsProcessFormCode)
Debug.Print("me.width={0} me.height={1} cs.width={2} cs.height={3}", Me.Width, Me.Height, Me.ClientSize.Width, Me.ClientSize.Height)
If mIsProcessFormCode Then
'process text file
End If
Catch ex As Exception
Debug.Print(ex.ToString)
End Try
End Sub
和调试输出:
routine=frmMain_Load
routine=frmAlert_Load mIsProcessFormCode=False
me.width=390 me.height=200 cs.width=374 cs.height=162
routine=frmAlert_FormClosing mIsProcessFormCode=False
routine=frmAlert_FormClosed mIsProcessFormCode=False
frmWidth=390 frHeight=200 frCsWidth=374 frCsHeight=162
routine=Button1_Click
routine=frmAlert_Load mIsProcessFormCode=True
me.width=390 me.height=200 cs.width=374 cs.height=162
我相信这就是我想要的。所有 frmAlert 大小都与我在 IDE 设计器中的大小相匹配。如果您能想到任何修改,请告诉我。非常感谢。
