当应用程序收到通知时,我需要让我的vb.net应用程序能够闪烁/闪烁以吸引用户的注意.

就像这个图像中的DW图标一样:

我已经谷歌搜索了一段时间,并尝试了各种代码示例,都没有成功.

这是我到目前为止所得到的:

    Public Class FlashWindow
        Private Declare Function FlashWindow Lib "user32" (ByVal hwnd As Long, ByVal bInvert As Long) As Long
        Shared Sub main()
        FlashWindow(Me.Handle, 1)
        End Sub
    End Class

此代码立即抛出以下错误:

'我'仅在实例方法中有效

任何人都可以让我知道我哪里出错或如何实现这一目标？

我需要能够加密和解密 php 和 vb.net 中的字符串。PHP 需要能够解密在 vb.net 中加密的字符串，而 vb.net 需要能够解密在 php 中加密的字符串。

我在两个环境中都有可以在该环境中工作的工作代码，但它们不能相互协作。

我对此进行了大量搜索，我相信这与 AES256 的 openssl 实现以及它与 IV 或类似的东西加盐的方式有关。

vb 实现为 IV 生成一个随机 GUID，并在对其进行 base64 编码之前将其添加到加密字符串中。

我的 vb.net 代码是这样的......

Imports System.IO
Imports System.Text
Imports System.Security.Cryptography


Public Class tbSecurity

Public Shared enckey = "00000000000000000000000000000000"
Public Shared Function AESEncryptStringToBase64(strPlainText As String) As String
    Dim Algo As RijndaelManaged = RijndaelManaged.Create()

    With Algo
        .BlockSize = 128
        .FeedbackSize = 128
        .KeySize = 256
        .Mode = CipherMode.CBC
        .IV = Guid.NewGuid().ToByteArray()
        .Key = Encoding.ASCII.GetBytes(enckey)
    End With …

Am having a problem with a BackgroundWorker getting stuck. have thrown in loads of console.writeline's to help try and narrow down where the issue is, but am getting nowhere fast.

I noticed when going back through the output, I have this message... The thread 0x2d68 has exited with code 259 (0x103)

Can anyone tell me what that means?

EDIT - Below is my full code. To give some background, this app is processing requested received from a website to deploy …
