Details - Evans FTP ActiveX / COM DLL Programming Solution

EvansFTP.ocx includes 2 controls. One is for creating multi-threaded FTP applications and one, called the EZ version, is for creating the more traditional synchronous or blocking type applications.

Evans FTP also includes a DLL that is identical in functionality to the EvansFTP.ocx, except it is designed to allow you to easily create formless FTP components.

Using EZ version components do not preclude you from spawning simultaneous FTP sessions, use non-blocking operations or implement advanced functionality. However, using the multi-threaded components provides performance and handling improvements at the cost of a slightly steeper learning curve.

Both the EZ and the multi-threaded Evans FTP components provide the same methods, properties and enumerations. However, the multi-threaded version provides most of the FTP functionality through our epWINet object. EpWINet is a member of EvansFTP.ocx that represents one FTP session. The EZ version provides FTP functionality directly from the component.

For the architectural details of the multi-threaded components, please refer to the Component Map

Enumerations

EpWINet.epWINetStatus - A value reported by a Status Event. This value is determined by information from epWINET.DLL as communications occur between a local PC and remote server.
Name		Description

epWINetResolvingName		Value = 10. Looking up the IP address of the server.
epWINetNameResolved		Value = 11. Successfully found the IP address of the remoteAddress specified or implied by the Connect.

Component Map (applicable to multi-threaded only)

The Evans FTP multi-threaded components contain Connect and Disconnect methods which communicate with the Thread Manager (EpFtpThd). The Thread Manager automatically creates and destroys threads. Each Connect creates a thread and each Disconnect removes a thread.

Each new Thread instantiates an EpWINet object that can be referenced through the EvansFTP.Threads collection by specifying the key used during Connect.

Each EpWINet object communicates with the Microsoft WININET.DLL. Events are reported back through the EpFtpThd thread manager to the Evans FTP control.

Examples

Many of our competitors claim that their FTP components will do this or that "with only a single line of code". Well... ...we won't go there. However, we will say this. You will not find easier to maintain code, and you cannot write code with fewer lines, than you can using Evans FTP!

VBA Example - Uploads, downloads, executes remote commands (and displays the results), includes error handling plus a few other features with less than 40 lines of code.

VB Example - An FTP browser that displays and navigates files and folders, listing file and folder last modified date, name, attributes and size, includes minimal error handling and all in under 50 lines of code.
