run a windows exe

[lefedad]

I have an application where I want to use an electronic signature pad. I have to run a Windows program SignatureCapture.exe to communicate with the device. How do I call the exe from my Ext JS program?

The browser security model prohibits launching exe's from within a web page. This is not an Ext JS restriction, it's a security mechanism built into all browsers. With that said, you could use the wscript.shell ActiveX but that only works in Internet Explorer. Have you looked at whether your signature pad device has a development kit available? That should instruct you on how you can integrate the signature pad with your browser apps.
