Upload Files to a Web Server - Simplest Example

This is the simplest example for uploading some files to a web server. the BlockingUpload call is synchronous and returns when the upload is finished (or failed). The Chilkat Upload software is freeware and may be used in both commercial and non-commercial applications and websites.

The C# code to receive the upload at http://www.chilkatsoft.com/receiveUpload.aspx may be seen here: C# ASP.NET Code to Receive Upload

    HCkUpload upload;
    BOOL success;

    upload = CkUpload_Create();

    //  Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc)
    //  that will process the HTTP Upload.
    CkUpload_putHostname(upload,"www.chilkatsoft.com");
    CkUpload_putPath(upload,"/receiveUpload.aspx");

    //  Add one or more files to be uploaded.
    CkUpload_AddFileReference(upload,"file1","dude.gif");
    CkUpload_AddFileReference(upload,"file2","pigs.xml");
    CkUpload_AddFileReference(upload,"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.

    success = CkUpload_BlockingUpload(upload);
    if (success != TRUE) {
        printf("%s\n",CkUpload_lastErrorText(upload));
    }
    else {
        printf("Files uploaded!\n");
    }


    CkUpload_Dispose(upload);
