The following example will ' add a connection to a network share and ' will disconnect from the same share. ' By: Amitya (from psc cd) ' ' ' Inputs:Computer Name UserName Password ' ' Returns:Connection Successfull Connection Unsuccessfull ' 'Assumes:U can connect programmatically ' to another computer on LAN ' 'Side Effects:1. Create a new Standard E ' XE project. 2. Add a module to the project. 3. Copy and paste the following Declares and Type into the module: (NOTE: If you add this to a Form module, make all entries Private.) 4. Add two CommandButtons to Form1. These will be Command1 and Command2 by default. 5. Add the following code to Form1, substituting a valid share name for "\\ServerName\ShareName": Run the project and click on Command1. You will get a Message dialog indicating success or failure. If successful, you should be able to look in Windows Explorer and see the new connection (unless you left lpLocalName undefined, in which case the connection does not show in Explorer). Click Command2 and go to Explorer, where you should see that the connection has been removed.
