New Post: Decimal values problems
Hi Igor,
Sure. One thing you could do is use a host method to operate on decimal values:
Another possibility might be to use a host method to cast decimal values to a type that VBScript can deal with:
Good luck!
Can you give me example?
Sure. One thing you could do is use a host method to operate on decimal values:
scripter.Script.add = new Func<decimal, decimal, decimal>((a, b) => a + b); Console.WriteLine(scripter.Evaluate("add(num1, num2)"));
scripter.Script.toDouble = new Func<decimal, double>(value => (double)value); Console.WriteLine(scripter.Evaluate("toDouble(num1) + toDouble(num2)"));

It's not solution for our legacy application, we can't fix all customer scripts.
Anyway thanks a lot.

That break compatibility with legacy application. We can't change client scripts.

What VBScript data type do the scripts use for which you're trying to provide decimal values? Is it
currency?↧
New Post: Problem with nullable property of object
Understood. Unfortunately there seems to be no way to marshal
nothing into the script engine. That is, there's no value we can return from the host that VBScript will interpret as nothing. We can marshal in null and empty, but not nothing. And marshalling nothingout of VBScript doesn't work; the result on the host is null.↧

Try use DispatchWrapper.

Yes, it's a currency

You're absolutely right! A value of

Thanks again!
new DispatchWrapper(null) is picked up as nothing on the VBScript side. Thank you!We'll be happy to add
null<-> nothing marshalling to ClearScript, but it'll have to be optional to avoid breaking existing code. A new engine flag seems like a sensible approach.Thanks again!

Thanks. Is there nightly builds of the ClearScript?

Hi Igor,
No, but we just posted a source code update that includes the new marshaling options. If you get a chance, please give them a try and let us know if they work for you.
Thanks again!

Hi,
It's work. Thanks a lot.
If you have some progress with cloning of script engine, please update the source code. I use with source code of script engine and have modified version of the ClearScript.

New Post: Getting JS exception
Hello!
Currently there's no plan beyond adding a script-callable
Thanks for your input!
Is there any plan to have more seamless exception handling between .NET and JS, even for V8 only?
Currently there's no plan beyond adding a script-callable
tryCatch() function on the host side. Generally we favor keeping the engine APIs uniform, but we agree that this may be worth doing anyway, so we've put it on our long-term to-do list.Thanks for your input!
