FCKeditor asp.net upload Attachment Research _ Web Editor

1, installation
Installation is not much said, in addition to the general compression package, ASP. NET version of FCKeditor has another fckeditor.net download package, which has a Visual Studio solution,bin/ There is a FredCK.FCKeditorV2.dll file in release that you can copy directly into the bin folder of your ASP.net project.

2, attachment upload process
FCKeditor opens a modal dialog box by clicking the link or Picture button in the edit interface, and then uploading the local file in it.
This dialog box is fckeditor/editor/dialog/fck_image.html or fck_link.html.

The JS code for the dialog box is in the Fck_image and Fck_link directories, and they also call Common/fck_dialog_common.js

These are the client's business.

Under the fckeditor/editor/filemanager/upload/aspx there is a lonely upload.aspx, inside in addition to the annotation only a word, its code behind The code is in the front of the asp.net download package Uploader.cs, has been compiled into the FredCK.FCKeditorV2.dll.

3. Modify Uploader.cs
3.1 Modify the only line of code on the upload.aspx.

Original:<%@ page autoeventwireup= "false" inherits= "FredCK.FCKeditorV2.Uploader" language= "C #"% >
Modify to:<% @ Page autoeventwireup= "false" codefile= "Upload.aspx.cs" inherits= "Fckupload" language= "C #"% >

In this way, upload.aspx no longer go to FredCK.FCKeditorV2.dll to find their own behind code, but to find their side.

3.2 Extract the Uploader.cs from the Fckeditor.net compression package and place it in the FCKeditor directory of your ASP.net project and upload.aspx. In this way, Uploader.cs is a part of your project, completely under your control.

First, you should add your own authentication.
Then, httppostedfile ofile = request.files["NewFile"];, to get uploaded files, the FCKeditor customer should be uploading only one at a time, without having to consider multiple simultaneous uploads.

Get file size, ofile.contentlength.
Get filename, httpcontext.current.request.files[0]. FileName,
To check the suffix, System.IO.Path.GetExtension (FileName);

Save it, Ofile.saveas (sfilepath); The filename and path are completely in your control.

Finally, the error code sent back through the Sendresults, if uploaded successfully, you can send 0, then the filename and file URL.

3.3 Client
