Hey, you need to use a html download code, this is a code that I have found searching through the internet (for c#): Add a two text boxes, call them 'txtUrl' and 'txtPath'. And add all of that code to a button (called what ever you want). Make sure you include using System.Net; using System.IO; using System.Threading; try { // Create a request to the file we are downloading webRequest = (HttpWebRequest)WebRequest.Create(txtUrl.Text); // Set default authentication for retrieving the file webRequest.Credentials = CredentialCache.DefaultCredentials; // Retrieve the response from the server webResponse = (HttpWebResponse)webRequest.GetResponse(); // Ask the server for the file size and store it Int64 fileSize = webResponse.ContentLength; // Open the URL for download strResponse = wcDownload.OpenRead(txtUrl.Text); // Create a new file stream where we will be saving the data (local drive) strLocal = new FileStream(txtPath.Text, FileMode.Create, FileAccess.Write, FileShare.None); // It will store the current number of bytes we retrieved from the server int bytesSize = 0; // A buffer for storing and writing the data retrieved from the server byte[] downBuffer = new byte[2048]; // Loop through the buffer until the buffer is empty while ((bytesSize = strResponse.Read(downBuffer, 0, downBuffer.Length)) > 0) { // Write the data from the buffer to the local hard drive strLocal.Write(downBuffer, 0, bytesSize); } } finally { // When the above code has ended, close the streams strResponse.Close(); strLocal.Close(); } Make sure you include this in the public // The stream of data retrieved from the web server private Stream strResponse; // The stream of data that we write to the harddrive private Stream strLocal; // The request to the web server for file information private HttpWebRequest webRequest; // The response from the web server containing information about the file private HttpWebResponse webResponse; // The delegate which we will call from the thread to update the form private delegate void UpdateProgessCallback(Int64 BytesRead, Int64 TotalBytes); If you have any problems please ask ;)
