我在任何地方都找不到答案。我定义了一个表单控件集合的新实例,但在运行时,该集合为空。它适用于表单上的一个加载按钮,但不适用于另一个。代码完全相同,但一个有效,另一个无效。以下是相关代码:
Private Sub miFLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles miFLoad.Click
Dim FilePath As String = "C:\FList\FList.flt"
Dim LoadFile As New SaveandLoad.SaveAndLoad
Dim FileRead As New Simple3Des("MyPassword")
Dim FileString As String = FileRead.ReadFile(FilePath)
With LoadFile
.WhichList = dgFList
.FilePath = FilePath
.DecryptedString = FileRead.DecryptData(FileString)
End With
Call LoadFile.LoadFile()
End Sub
此加载按钮未加载
Private Sub miCLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles miCLoad.Click
Dim FilePath As String = "C:\FList\CList.clt"
Dim LoadFile As New SaveandLoad.SaveAndLoad
Dim FileRead As New Simple3Des("MyPassword")
Dim FileString As String = FileRead.ReadFile(FilePath)
With LoadFile
.WhichList = dgCourses
.FilePath = FilePath
.DecryptedString = FileRead.DecryptData(FileString)
End With
Call LoadFile.LoadFile()
End Sub
这个是。
Public Sub LoadFile()
Dim dgRow As DataGridViewRow
Dim dgCell As DataGridViewTextBoxCell
Dim Lines() As String = DecryptedString.Split(vbLf)
Dim LinesList As List(Of String) = Lines.ToList
LinesList.RemoveAt(Lines.Length - 1)
For Each Line As String In LinesList
Dim Fields() As String = Line.Split(",")
dgRow = New DataGridViewRow
For x = 0 To (WhichList.Columns.Count - 1) Step 1
dgCell = New DataGridViewTextBoxCell
dgCell.Value = Fields(x).ToString
dgRow.Cells.Add(dgCell)
Next
WhichList.Rows.Add(dgRow)
Next
Dim FormControls As New frmFacultyList.ControlCollection(frmFacultyList)
For Each DGV As DataGridView In FormControls
If WhichList.Name = DGV.Name Then
DGV = WhichList
DGV.Refresh()
End If
Next
End Sub
这是他们将信息传递到的地方。同样,对于 FLoad 按钮单击,FormControls 变量为空,但对于 CLoad 按钮单击则不是。任何帮助,将不胜感激。
编辑:对不起,这里是相关的公共属性
Public Property WhichList As New DataGridView
Public Property FilePath As String
Public Property DecryptedString As String
Public Property EncryptedString As String
