我正在爲我自己的目的製作一個數字生成器。 我已經做它與使用這些功能: - 保存生成的數字如何從保存的文件中獲取保存的文本
我想要什麼功能: - 當我關閉它加載從記事本的最後生成的數字。
這裏是代碼:
Private Const FilePath As String = "C:\Users\sto0007404\Documents\Numbers.txt"
Private CurrentNumber As Long
Private Sub Command1_Click()
CurrentNumber = CurrentNumber + 1
txtRefNo.Text = "EM" & Format(CurrentNumber, String(4, "0"))
End Sub
Private Sub Form_Load()
Dim TextFileData As String, MyArray() As String, i As Long
' Open file as binary
Open "FilePath" For Binary As #1
' Read entire file's data in one go
TextFileData = Space$(LOF(1))
Get #1, , TextFileData
' Close File
Close #1
' Split the data in separate lines
MyArray() = Split(TextFileData, vbCrLf)
For i = 0 To UBound(MyArray())
' Set CurrentNumber equal to the current max
CurrentNumber = Val(Mid$(MyArray(i), 2))
Next
End Sub
Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
Dim i As Long
' delete the old file
If Not LenB(Dir(FilePath)) = 0 Then Kill FilePath
'open the file for writing
Open FilePath For Output As #1
For i = 1 To CurrentNumber
Write #1, "EM" & Format(i, String(4, "0"))
Next
'close the file (if you dont do this, you wont be able to open it again!)
Close #1
End Sub
