我在我的項目中有一個保存按鈕,它應該將我的2個列表框的內容保存到文本文件中,但它不保存所有內容。相反,它會刪除其中一個列表框的最後5行。我的代碼有什麼問題?保存按鈕不保存所有內容
Dim loops As Integer 'Declare variable
Dim savefile As New SaveFileDialog
savefile.FileName = ""
savefile.Filter = "textfiles(*.txt)|*.txt|file(*)|*|All files('.')|'.')"
savefile.Title = "save"
savefile.ShowDialog()
Try
Dim write As New System.IO.StreamWriter(savefile.FileName) 'Write and save a new file
For loops = 1 To itemcount - 1 'loop until no lines are left in listbox
write.WriteLine(firstname(loops)) 'Write out firstname
write.WriteLine(lastname(loops)) 'Write out lastname
write.WriteLine(gender(loops)) 'Write out gender
write.WriteLine(applicationdate(loops)) 'Write out date of regestration
write.WriteLine(address(loops)) 'Write out address
Next
write.Close() 'Close file
MsgBox("File Saved") 'Display message box
Catch ex As Exception
End Try
你從哪裏得到itemcount的價值? – Steve 2012-08-12 14:40:07
是被拋出的異常嗎?你的代碼默默地忽略任何異常。 – 2012-08-12 14:42:01
是的,正如@orzechowskid所說,刪除那個空的catch,看看Index超出範圍的異常是否出現 – Steve 2012-08-12 14:48:39
