按下“取消”按钮时出现问题在OpenFileDialog中 [英] Problem when pressed "cancel" in OpenFileDialog
问题描述
Vb.net 2005快递我一直在努力，问题是：我用
openfiledialog来浏览文件，我创建了一些代码来执行文件
用OK按钮，没问题。但如果我按取消按钮作为openfiledialog框的
结果，例如我的文件名''被添加到
列表框中，或者我的音频文件从头开始播放。
更好地解释：
openfileplaylist.ShowDialog（）
ListBox1.Items.Add（openfileplaylist.FileName）
1 - 如果单击确定，该代码会将文件路径添加到列表框中，但是如果我单击
" cancel"它添加了OpenFileDialog1文本到列表框中。为什么？
2 - 我还希望我的文件仅作为文件名列出，而不是完整的路径，如
c：\ blabla \ blaba \ kklj \ bla.mp3。
这2个问题对我来说非常重要。
感谢您的回答。
Hi,
Vb.net 2005 express i''ve been working, the problem is: I use
openfiledialog to browse files, i created some code to execute file
with OK button, no problem. But if i press "cancel" button as the
result of openfiledialog box, for example my filename''s are added into
listbox or my audio file is being played from the beginning.
To explain better:
openfileplaylist.ShowDialog()
ListBox1.Items.Add(openfileplaylist.FileName)
1-That code adds file path into list box if click OK, but if i click
"cancel" it adds "OpenFileDialog1" text into listbox. Why?
2-Also i want my files listed only as "filenames", not full path like
c:\blabla\blaba\kklj\bla.mp3.
These 2 questions are very important for me.
Thanks for the answer from now.

您好，
请尝试以下代码：
Dim openfileplaylist As New OpenFileDialog
....
如果openfileplaylist.ShowDialog（）= DialogResult.OK那么
Dim temp_string As String
Dim a As Integer
temp_string = openfileplaylist.FileName
''删除.mp3
temp_string = temp_string.Substring（0，temp_string.Length - 4）
''找到最后的位置" \"
a = temp_string.LastIndexOf（" \"）
'''普通文件名
temp_string = temp_string.Substring（a + 1）
ListBox1.Items.Add（temp_string）
其他
女士gBox（没有加载文件。）
结束如果
问候，
Oliver
Hello,
Please try this code:
Dim openfileplaylist As New OpenFileDialog
....
If openfileplaylist.ShowDialog() = DialogResult.OK Then
Dim temp_string As String
Dim a As Integer
temp_string = openfileplaylist.FileName
''remove the .mp3
temp_string = temp_string.Substring(0, temp_string.Length - 4)
''find position of last "\"
a = temp_string.LastIndexOf("\")
''retrieve the plain file name
temp_string = temp_string.Substring(a + 1)
ListBox1.Items.Add(temp_string)
Else
MsgBox("No file was loaded.")
End If

你肯定向OP展示了一个实现他想要的东西的方式，但是更简单的方法是：
更简单：
如果openfileplaylist.ShowDialog（）= DialogResult.OK那么
ListBox1.Items.Add（Path.GetFileName（openfileplayli st.FileName））
否则
MsgBox（没有加载文件。）
结束如果

新闻：A5 ******************** ************** @ microsof t.com ...
Youv''e certainly shown the OP a ''way'' to achieve what he wants but a much
simpler way would be:
If openfileplaylist.ShowDialog() = DialogResult.OK Then
ListBox1.Items.Add(Path.GetFileName(openfileplayli st.FileName))
Else
MsgBox("No file was loaded.")
End If
