从资源启动可执行应用程序而不将其保存在某处 [英] start an executable application from resources without saving it somewhere

问题描述

如果我的 VB 2008 应用程序 (myVbApp.exe) 的资源中有一个文件 (appres.exe)，我该如何从那里开始?我不想在开始之前将它 (appres.exe) 保存在其他地方，我只想要 myVbApp.exe，没有更多文件.

If i have a file ( appres.exe ) in the resources of my VB 2008 Application (myVbApp.exe), how can I start from there? I don't want to save it (appres.exe) somewhere else before start, i want only myVbApp.exe, no more files.

推荐答案

从资源中检索 EXE:

Retrieve the EXE from the resources:

   Dim l as System.IO.Stream = Reflection.Assembly.GetEntryAssembly.GetManifestResourceStream(String.Format("{0}.{1}", "ApplicationProjectName", "YourExeName"))

然后将其保存到临时文件夹 - 示例方法:

Then save it to temp folder - example method:

Private Sub SaveStreamToFile(ByVal p_stream As Stream, ByVal p_fileName As String)
    Dim l_streamWriter As System.IO.FileStream = System.IO.File.Create(p_fileName)

    Try
        Dim l_bytes(65536) As Byte
        Dim l_offset As Integer = 0
        Dim l_readBytes As Integer

        Do
            l_readBytes = p_stream.Read(l_bytes, 0, 65536)
            l_streamWriter.Write(l_bytes, 0, l_readBytes)

            l_offset += l_readBytes

        Loop While (l_readBytes > 0)
        Debug.WriteLine("Num Of bytes Read: " + l_offset.ToString)

    Catch ex As Exception
       'log error
    Finally
        p_stream.Close()
        l_streamWriter.Close()
    End Try
End Sub

现在您在临时文件夹中获得了 EXE，您可以定期使用:

Now that you got the EXE in a temp folder, you can regulary lunch it using:

Process.Start("EXE_PATH")

并在该过程完成后将其删除.

And delete it once the process is done.
