Visual Basic 6.0 • VB.NET. Get FTP Directory Listing Information. Visual Basic 6.0 example showing how to get information about files and subdirectories in. ![]() ![]() For Microsoft Office users, Visual Basic (VB) is a mighty power tool. Repetitive and longwinded operations have become a one button task, saving countless hours of our time, not to mention brain cells. With it, we can move and organise data, save files, process emails and more. But the scope of its functions is not just contained within the Office software, VB can interact with many parts of our computers. For this Instructable, I’m going to show how we can use VB to upload files (not limited to office files) to an FTP file server with ease. We’re going to achieve this with a simple.bat file that will execute commands via the command line interpreter. In the next few steps we will learn about the.bat file and the command line interpreter, so if you’re looking to get stuck in with the code, you may skip these steps. Let’s start this the manual way to get a feel for how this part works. Open up your Command Prompt in Windows, command prompt works in a similar way to the Interpreter, so it helps to know what’s going on to hep understand the VB code later. On the first line in Command Prompt type in the following line, replacing myserver.com with your ftp server. Ftp ftp.myserver.com The two parts to this line are ‘ftp’, which tells the command you are connecting via ftp protocol, and the second part ‘ftp.myserver.com’ which you will put in the address of your file server. You will then be prompted for your user name and password on separate lines. Type these in and press enter to see the following on a separate line ftp> This means we are connected and ready to upload or download. To change the local directory type in the following line. Lcd “C:/Users/Me/My Documents/” This will set the location where the files we wish to upload or download are stored on our computer. Also note, the quotes are only needed where this is a space in the directory name. You will receive a message line starting with OK, if the directory change was successful. To change the remote directory type in the following line. Cd your/remote/destination/ Again, you will receive a message line starting with OK if the remote folder change was successful. Now to send a file. Type to following line into command prompt and press enter, replacing myfile.png with your desired file. Put myfile.png This line is telling the command prompt to send file the C:/Users/Me/My Documents/myfile.png to the your/remote/destination/ folder on the server, of course your details will be in there. You will then see a line stating the following 226 File successfully transferred What does ‘put’ mean? It simply means put this file there. What if I want to send all the files in the folder? Then we use ‘mput’ with a wildcard as below mput *.png Will send all.png files in the folder mput * Will send all files in the folder mput a* Will send all files starting with an ‘a’ in the folder Once we have finished our uploads, we can type in ‘bye’ on a new line to close the connection, then 'exit' to close the command prompt. Now we’ve covered those basics we can get stuck into the Visual Basic aspect in the next step. Please note, this won’t be a full guide on how to use VB, I’m assuming you are here because you can use its basic functions already.

The first will store our local directory and the rest will be variables to create our text file and.bat file. Dim MyDirectory As String Dim File1 As Integer Dim File2 As Integer File1 = FreeFile File2 = FreeFile Now we need to set a directory to store the temporary ftp command files, this can be any directory of your choosing. Try to make it an unused directory as the program will erase all.txt.bat and.out files each run. MyDirectory = “C: Temp FTPFiles' If we use this folder often we might want to check for any.out completion files and erase them from this directory, we can do this with the below code If Dir(MyDirectory & '.out') ' Then Kill (MyDirectory & '.out') Next we will create our first text file and enable us to write command lines to it under the name #File1 Open MyDirectory & '.txt' For Output As #File1 Now we begin writing out ftp commands to this file. These are very similar to the command prompt we did earlier, but please pay attention to the syntax used. First off, the connection to the ftp server. Each line we wish to write to file has to start with the word Print, then we list the file name then the text to write in quotes. Print #File1, 'open ftp.myserver.com' Next will be our user name for this ftp directory, substituting ‘my_username’ for your actual user name. Print #File1, “my_username” Next the password, again substitute, ‘your_password’ with your actual password.
