System.IO.File.WriteAllText Opens After Writing?
Jul 27, 2011Basically I am saving text to 2 seperate ini files, also saving the checkbox.checked value so my form can skip the login and auto start. My only problem is when a user saves the information to the INI files after writing them they automatically open up the INI files for display. When the form loads it automatically fills in the fields and if the checkbox is active it checks all the correct details then starts, only problem is it loads the checkbox1.checked ini file then starts the main menu. How can I skip this? and make it not show the ini files everytime they are called upon?

C# - File Upload Link Clears When Page Reloads?
Apr 11, 2009I am using ASP.net(2.0) with VB.NET.
I have a User registration form. On that form the user supply all his contact details and he can upload a image with the normal file upload control in ASP.net.
This is my problem. If anything goes wrong on the page then i give the User a error message saying what he left out or what went wrong. But the page refresh when that does happen. NOW the link to the image the user selected is gone. NOW when the user fix his error he thinks that he is uploading a picture but he never did because when the page re loaded it removed the link to his image inside the file upload control.
Note, the user don't have to upload a image, so there will be no error when the field is blank.

I have the jQuery timer working already, but the file isn't displaying. My plan was to get the jQuery to load a Controller Action every 5 seconds and have this action return a FilePathResult.
The script:
$(function () {

LiveStreamPath contains the path to the text file. I was thinking of creating a StreamReader in the Action instead. What sorts of implementations can I use to get this file to stream?
