问题描述
我需要使用Shell32解压缩应用程序中的某些文件.现在,我使用srcFolder.CopyHere(destFolder.Items())
来实现这一目标.但是,我的下一行代码需要新创建的ZIP文件.但是由于CopyHere
方法是Async,如何检查它何时完成?现在,我使用Thread.Sleep
大约500毫秒,这足以让我的计算机完成创建ZIP文件的操作,但这不是imo好的代码.
I need to unzip en zip some files in my application using Shell32. Right now, I use srcFolder.CopyHere(destFolder.Items())
to achieve this. However, my next line of code requires the newly made ZIP-file. But since the CopyHere
method is Async, how can I check when it in finished? Right now I use a Thread.Sleep
for around 500 ms which is enough for my computer to finish creating the ZIP file, but it's not good code imo.
有什么想法吗?
如有必要,可以提供更多的信息/代码.
More info/code can be provided if necessary.
推荐答案
我找到了它,使用了类似的东西:
I found it, used something like this:
srcFolder.CopyHere(destFolder.Items())
While FileInUse(FILEPATH & "BudgetJaarOverzichtSMB.zip")
Thread.Sleep(100)
End While
Private Function FileInUse(ByVal FilePath As String) As Boolean
Try
FileOpen(1, FilePath, OpenMode.Input)
FileClose(1)
Return False ' File not in use
Catch ex As Exception
Return True ' File in use
End Try
End Function
并不是很完美,但是与我的第一种方法相比,所花费的时间更少.
Not really perfect but will lose less time than with my first approach.
