Call A Subroutine From Javascript - ASP.NET - Java - VB And AJAX?
May 31, 2011I have an ASP.NET application with a button that executes VB.NET on the server when clicked. Specs have changed, I've added a menu of sorts which is to replace the VB button. With some from S.O., I've managed to manipulate some javascript which does a postback and executes the button's code. I figured I could just make the button invisible and still be able to call it's on_click event from js. How wrong I was!
So now, somehow I'm supposed to call a VB sub from either javascript or (boss says) ajax. I have no idea how to do this. Could anyone give me a good direction as to how I can call a VB.NET subroutine from ajax on the client? Or javascript?

.net - ByRef Underlined With "Expression Expected" Error When Trying To Pass In A Object Of Type List(Of ClsFooDetail)?
Mar 3, 2010I work with C# 99% of the time. However, I'm having to update some legacy VB.Net code and encountering an issue with VB.Net code syntax. The error that I get is "ByRef" is underlined and "Expected Expression" tag shows up when you hover over "ByRef". The "FooDetail.Load" function is written in C# and expects a List object passed as reference. Don't have any trouble using the same function in other C# classes.
