Boolean ObjectName. HTTPUploadAllThroughPostAsMultiPageTIFF(String HTTPServer, String ActionPage, String FileName)
String HTTPServer: the name of the HTTP server.
String ActionPage: the specified page for posting image files. This is the relative path of the page, not the absolute path. For example: "upload.asp", not "http://www.webserver.com/upload.asp". This is the page corresponds to the action in <form> html tag: <form id = "frmSample" action = "upload.asp" method = post>...</form>
String FileName: the name of the image to be uploaded.
Boolean.
TRUE indicates success. FALSE indicates failure.
When an error occurs and IfThrowException property is TRUE, an exception will be thrown.
When FALSE is returned or an exception is thrown, check ErrorCode property and ErrorString property for error information.
The field name of the uploaded image is RemoteFile.
IMPORTANT: Dynamic Web TWAIN uses a special way to see if an image is uploaded and processed successfully by server. If the server returns 0 bytes, indicates success. Otherwise, indicates failure. In other words, when the uploaded image is processed successfully, the action page on the server should not return anything, even the "<HTML>".
