wodFTPServer is a high-performance ActiveX and COM component developed by WeOnlyDo! Software. It allows software developers to easily embed robust server-side file transfer functionalities into their custom Windows applications. Instead of acting as a standalone, ready-to-run application, it provides the backend infrastructure for developers using languages like VB6, C#, Delphi, Visual C++, and VB.NET. Key Features of wodFTPServer
Multi-Protocol Support: Implements standard FTP, secure FTPS (FTP over SSL/TLS in explicit and implicit modes), and SFTP (secure FTP over SSH2).
Unified Programming Interface: Developers can switch the server’s operational protocol entirely by altering a single Protocol property without rewriting code.
Granular Event Control: Offers an extensive set of events that trigger during client actions, such as connecting, authenticating, listing directories, downloading, and uploading files.
Robust Security & Authentication: Supports traditional passwords alongside corporate-grade security like digital X.509 certificates and SSH private key authentications.
Virtual Folders: Allows developers to expose customized, non-existent, or abstract directory pathways to connected clients without modifying the physical server disk structure.
Large File Infrastructure: Fully supports handling and transferring massive files larger than 4.2 GB. Component Varieties
The installer includes two structural variants depending on your project architecture:
ActiveX Control (wodFTPD.ocx): Designed for visual drag-and-drop implementation inside application forms.
COM Object (wodFTPD.dll): A windowless variation optimized for background initialization, runtime scripting, or Windows Services. Step-by-Step Setup Guide
Because wodFTPServer is a development component, setting it up involves referencing it in your integrated development environment (IDE) and initializing it via code. Step 1: Download and Installation
Obtain the installation package directly from the WeOnlyDo! Software product page.
Run the installer executable to unpack the necessary files to your machine.
The installation automatically registers the 32-bit and 64-bit DLL and OCX components within the Windows registry. Step 2: Reference the Component in Your Project
For Visual Basic 6 / Delphi: Open your form designer, right-click your toolbox, select components, and check wodFTPServer ActiveX Control. Drag and drop it onto your form.
For .NET (C# / VB.NET): Open your project in Visual Studio. Right-click References, click Add Reference, browse to the COM tab, and select WeOnlyDo wodFTPServer. Step 3: Initialize and Start the Server
To spin up a basic secure SFTP or standard FTP listener, declare and initialize the component in your source code:
// Example using C# and the COM Object wodFTPDCom FTP_Server = new wodFTPDCom(); // 1. Choose protocol: FTP, FTPS, or SFTP FTP_Server.Protocol = wodFTPDCOMLib.ProtocolsEnum.SubsystemSFTP; // 2. Set the port (21 for FTP, 22 for SFTP, 990 for Implicit FTPS) FTP_Server.Port = 22; // 3. Allocate a valid cryptographic key if using SFTP/FTPS wodKeysLib.Keys privateKey = new wodKeysLib.Keys(); privateKey.Load(“/path/to/server_key.rsa”, “optional_password”); FTP_Server.PrivateKey = privateKey; // 4. Start the listener service FTP_Server.Start(); Use code with caution. Step 4: Handle User Authentication
The server will not allow connections unless you instruct it how to handle credentials. You must implement the component’s LoginUser event:
private void FTP_Server_LoginUser(wodFTPDCOMLib.User User, string Username, string Password, ref wodFTPDCOMLib.AccessAllowedEnum Allow) { // Validate credentials against your internal database or active directory if (Username == “admin” && Password == “secret123”) { Allow = wodFTPDCOMLib.AccessAllowedEnum.AllowReadWrite; User.HomeDir = “C:\SharedFolder”; // Dynamically bind a root folder for this session } else { Allow = wodFTPDCOMLib.AccessAllowedEnum.DenyAccess; // Reject unauthorized users } } Use code with caution. Step 5: Test the Integration
