FileReader() support in HTAs

Question

Does anyone know if HTAs support FileReader() when IE10 or IE11 are installed?

Example: var reader = new FileReader();

I'm getting "Object doesn't support this action" but FileReader() is supported on IE10 and IE11, so shouldn't it be available on HTAs too?

Thanks,

Mario

If you don't have this flag, try adding it to your HTA:

 <meta http-equiv="X-UA-Compatible" content="IE=10">

If other things fail, you can drop back to the windows API to read/write files:
