WebUpload Bean
Properties Methods Events Configuration Settings Errors
The WebUpload Component is used to upload files to RFC1867-compliant web servers.
Syntax
IPWorks.Webupload
Remarks
To use the component as a file upload client, provide the file names (paths) in the FileVars collection and optional form variables in the FormVars collection .
Then, set the URL property to the address of the page or script that accepts the files, and call the Upload method. Alternatively you can call the UploadTo method with URL as a parameter.
The UploadProgress event is fired during upload which shows the progress of the upload. The Transfer event shows the server response (normally an HTML page).
