人家都提供了sdk，直接调用即可
1、吧dll复制导foxtable安装目录，添加引用：http://www.foxtable.com/webhelp/topics/1936.htm
2、把附件的c#代码转换为vb代码即可：https://converter.telerik.com/，注意加上命名空间
dim url as string = "https://sdk.nuonuo.com/open/v1/services"
Dim appKey As String = "your.appKey"
Dim appSecret As String = "your.appSecret"
Dim taxnum As String = "your.taxnum"
Dim token As String = "your.token"
Dim senid As String = Guid.NewGuid().ToString().Replace("-", "").Substring(0, 32)
Dim method As String = "nuonuo.electronInvoice.CheckEInvoice"
Dim content As String = "{" & """invoiceSerialNum"":[""170**********1000004""]" & "}"
Return NuonuoSDK.NNOpenSDK.sendPostSyncRequest(url, senid, appKey, appSecret, token, taxnum, method, content)
