How to Run CMD in ColdFusion CreateObject
CMD runs the Windows command line from your ColdFusion project. You use the CreateObject class to run the CMD command on a user's computer, but your ColdFusion application must have permissions to run the app from the browser. The user receives a popup for permission, and if the user chooses "Yes," you can run CMD commands on the user's computer from your Web applications.

Run a Windows command line statement on the computer. For instance, the following code retrieves a list of files and directories using the "dir" command and returns the list to the "myfiles" variable:
<cfset myfiles = mycmd.execute("dir",30)>
The "30" parameter sets the timeout for the command, so if the command does not run successfully, a timeout error returns.

Display the results. The following ColdFusion code shows how to display the results of the CMD statement:
<cfoutput>
List of Directories: #result.getStandardOutput()#<br>
</cfoutput>
