JS中的大括号怎么转化到VB中，脑袋都想破了
我想给Acrobat做个自动签名的软件，在Acrobat_JavaScript帮助文档中看到以下内容：var ppklite = security.getHandler("Adobe.PPKLite");
ppklite.login("abc123", "/C/signatures/DPSmith.apf");
var f = this.getField("mySignature");
this.resetForm(["mySignature"]);
f.signatureSign( ppklite,
{ password: "abc123",
location: "San Jose, CA",
reason: "I am approving this document",
contactInfo: "dpsmith@,
appearance: "Fancy" });
以下为我写的内容，就是以上的的“signatureSign”不知道怎么转换，请大神教教我，已经想了好几天了，我对JS和VB都不怎么熟：
