If you want to give your users the opportunity to connect to network resources from within your program, all you have to do is call the "WNetConnectionDialog()" Win32 API function:
WNetConnectionDialog(
0,
RESOURCETYPE_DISK );
First parameter is the handle of the parent Window, so if you're calling "WNetConnectionDialog()" from a "form" window, you can pass "Handle" to make the network drives dialog a child window of the form.
WNetConnectionDialog(
Handle,
RESOURCETYPE_DISK );
