I was recently asked how you'd go about firing an EXE from a CRM button, now this isn't the best thing to be doing but here's how to do it.
Note: The exe path must be visible from the client machine.
Assuming that you want the button to appear on the entity form add the following to the isv.config:
<Button Icon="/_imgs/ico_18_debug.gif" JavaScript="fireExe();">
Now you need to add the following to the OnLoad event of the entity that displays the button:
fireExe = function()
{
var oShell = new ActiveXObject("WScript.Shell");
//Note: all back-slashes (\) must be doubled up (Single \ is a control character in JavaScript)
var prog = "c:\\WINDOWS\\System32\\notepad.exe";
oShell.run ('"'+prog+'"',1);
}
The above example will fire NotePad whenever the user clicks the button.
Note: Internet Explorer security settings will probably need to be changed for the Internet Zone that CRM is running under to allow ActiveX code to execute.
