I am developing an application that stores images as Base64 strings in xml files. I also want to allow the user to crop the image before saving it to the file, preferably all in memory without having to save a temp file, and then delete it afterwards. In order to display the newly uploaded image, I need to create a HTTP handler that I can bind the asp:Image to. The only examples for doing this online require passing the .ashx an ID and then pulling the image from a DB or other data store. Is it possible to somehow pass the raw data to the .ashx in order to get back the image?

View 3 RepliesI'm using the Ajax Toolkit Editor control on my page, and need to save the contents to an rtf file. I found a similar post, but I'm having trouble with the following method:
Protected Sub cmdSave_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Response.Clear()
Response.Buffer = True
Response.AddHeader("content-disposition", "attachment;filename=myfile.rtf")
Response.ContentType = "application/rtf"

This produces a file with the .rtf extension, but it merely contains plain text and html tags. Is it possible to save the contents of the Ajax Editor control as a true rtf?
