#include <CkUpload.h>

void ChilkatSample(void)
    {
    CkString strOut;

    CkUpload upload;

    // Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc)
    // that will receive and process the HTTP Upload.
    upload.put_Hostname("www.mywebserver.com");
    upload.put_Path("/receiveUpload.aspx");

    // Add one or more files to be uploaded.
    upload.AddFileReference("file1","dude.gif");
    upload.AddFileReference("file2","swordfish.xml");
    upload.AddFileReference("file3","sample.doc");

    // Do the upload.  The method returns when the upload
    // is completed.
    // This component also includes asynchronous upload capability,
    // which is demonstrated in another example.
    bool success = upload.BlockingUpload();
    if (success != true) {
        strOut.append(upload.lastErrorText());
        strOut.append("\r\n");
    }
    else {
        strOut.append("Files uploaded!");
        strOut.append("\r\n");
    }



    SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
