c# - How to capture file upload data from web page external to an ASP.NET site using .NET -


I know how to get the file from the client using standard ASP.NET techniques, however, I Data needs to be retrieved from a third party web page written in basic HTML and ASP.Net can process file data in web application.

So if the original HTML looks like this ...

& Lt; Input type = "submit" value = "click" /> & Lt; / Form & gt;

How do I obtain file data in the page referring to the action attribute of the form? So far, I have tried the following code, which allows me to use the filename - but there is no byte stream of the file. 

  Secure Zero Page_load (Object Sender, EventArgs E) {string fileName = Request.form ["fileUpload1"]; // no files appear in the request. The collection of files in the code below. Forward (string file files in request) {HttpPostedFile HPF = Request. Files [File] as HTML posted file; If (hpf.ContentLength == 0) continues; String savedFileName = Path.Combine (AppDomain.CurrentDomain.Base directory, path.getFileName (hpf.FileName)); Hpf.SaveAs (savedFileName);   
 
 
 Your form is incorrect  enctype  should be on the parameter  form  tag: 
 
  & lt; Form id = "form1" action = "WebForm.aspx" method = "post" encrypt = "multipart / form-data" & gt; & Lt; Input name = "fileUpload1" type = "file" /> & Lt; Input type = "submit" value = "click" / & gt; & Lt; / Form & gt;

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
