I have to read the first couple of lines of a csv file client side to present the user with a preview before uploading a large file.
I'm using c# with ASP.Net (VS2010)
Does anyone know how this can be done? Also that it works in all browsers!?!
(It's not possible to use activeX or so, we do not want our clients to install something!)
I have to read a client side ini file in Aspx page and use that data in server side processing. refer to a link or any sample if possible.
View 6 RepliesI've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?
View 1 RepliesI have a treeview which showcheckbox=true, when the checkbox is ticked I need to run a js function on client side and read the value of the checkbox
I set the treeNode1.value=i
In IE, I can get the value of each check box (which is i...)
but in chrome, firefox and safari, the value is always "On"
To my understanding the clinet side can only send data to the server either by get or post. so basically either through query string (get) or through body of the page (post).
So when we upload a file from client machine and send it to server, what exactly is happening behind the scenes? are we doing a post?
I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");
[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
I have a project of ASP.NET which is a Customer satisfaction Survey, i need to to incorporate the option selected by customer with the a client side text file which i located at the client machine, read a text file on client or should i develop the survey application as window application.

I need to save a text file on the client side possibly without permission. The case is that I need to save this text file in a shared folder in this or in another machine in the lan. This text file is going to be read automatically by the fiscal printer which will print the fiscal invoice. I have a asp .net web application and the server is not on the same lan with the fiscal printer, so I have to write it on the client-side. how to do this without asking to the user every time for the security issue.
I can accept a solution like, the client is asked only one time a the first printing, but not every time he wants to print a bill. Some kind of asking permission to the client for allowing this website, in order to not repeat the permission asking.

In ASP.Net, I want to give a user an ability to save the text entered in the textbox to the client machine. So that, user can copy paste it for later use.
Is there a way to show, save as dialog so that user can save the text in a text file on client machine? or, if there is any other alternative?
My requirement is to get the file size in client side. there is no problem in FF but in IE you can't do that unless u r using an activeX object. So we thought of putting it in browser cache and reading the file size from there and when we post it to the server we will be taking it from the cache and send it to the server.

View 4 RepliesI have a page setup that displays a datagrid connected to a access database file. I setup a timer to compare the last write time of the access db file and current time (with in 4 seconds). Once the times are with in 4 seconds of each other it requests a refresh of the data. The webpage is displayed on 4 thin client PC's with 0 user involvement so the WebPages need to update themselves. Due to the fact I'm limited to Access I'm trying to limit the # of times a day they are accessed by the auto-update.
The problem I'm having is when the timer ticks it POSTs to the web server. I have 3 WebPages setup watching 3 DB's for different location where I work but they all run of an IIS server in my office. So this creates a lot of unneeded traffic and log files. (Currently 5-6megs per day)
I was wondering there is a better way to compare the files on the clients machine and only post back for an update when they are with in 4 seconds of each other.
The site is built with MS visual web dev 2010 express written in Aspx and code lang is VB. I'm using system.io.file.getlastwritetime to get the file information for comparing.
