Title: Webserver - Upload and Process a CSV File
Post by: gavinwebb on February 13, 2012, 10:49:30 AM

From my web app I want the user to be able to upload a CSV file and then  for my program to process this file (will result in records being inserted into the database).

I have created a memory form with a file upload field.  When I run it I can see how it then opens a file select box - but then what?

What doe I need to do next - somehow it needs to be told to upload to some location on the server I guess.  Then when that's done I guess the process (which I can easily write) needs to be triggered.  How do I trigger this?  How do I know when it's done?

I'm happy to look at examples or documentation but can't seem to find anything (that makes sense to em anyway).

Thanks

Look at the file upload example. It shows how to rename the incoming file and place it in a different folder. It is after this point you can then process the file in the web handler.

I've also tweaked the File upload example in 6.19 to show how to create thumbnails of images when the file arrives, using Clarion FreeImage. This is an often-asked question. In your case you can do the work in the WebHandler, or in the Form itself - the example shows where to embed in both cases (in 6.19).
