i have winform application with method to generate excel report, now i want to transfer this to asp .net.
User click button and on the server side start method (generate excel report to temp file), then ready temp file transfer to client side. That's how i imagine this process in asp .net. There's no problem to transfer file from server side to client. Problem in process of generation excel report. Excisting code doesn't work, because excel application must be started and visible and how can i do this on server side?
Maybe this is absolutely wrong way and such things doing different way?
I have a requirement in which I have to call a JavaScript function in between my server side event and in that JavaScript function code I have to set hidden field value and in next line of that same event i have to use that hidden field value.
View 4 RepliesIf I have something like the following:
<asp:TextBox id="test" runat="sever"></asp:TextBox>
<asp:RequiredFieldValidator runat="server" ControlToValidate="test"
ErrorMessage="Required"></asp:RequiredFieldValidator>
<asp:Label runat="server" id="lblStatus"></asp:Label>
if in the code behind, I set the label to "You must enter a value if the textbox is empty" to validate it on the server side and this is fine, but if javascript is enabled, I don't want to show the client side validation and the server side label together. Is this something where I would just have to disable the client-side validators if javascript was enabled?
I am working with a chatServer application. I want to transfer(share) one file from client machine to another client machine, like gtalk file send without saving that file in server (I meen directly transfer from client to client). How can i do this in asp.net
View 7 RepliesWe've got a client app which connects using TCP to a server. Additionally, the client app makes use of .NET remoting to talk to another piece of locally running code.
I'm tasked with creating a "Client Simulator" to do some testing, where we'd need to have 100's of clients connected simultaneously to the server. Ideally, this would work out great if I were to run each client in it's own space, such as a VM, but this is not logistically feasible.
how to handle this? Is there a tool that could do something like this? Or some sort-of .NET concept I could use?
I have situation where I need to authenticate a client across multiple web services. Basically each service needs to identify the client and know a few other small pieces of information about the client.
The way I have it working now is that the needed identifying information is stored in a session table in a database by the authenticating web server. The web server hands the client an string, which IDs the database entry and gets passed to the other web services. The web services then use this string to pull the needed information about the client from the database entry.
It has occurred to me that it might be possible to give the client an encrypted blob that contains the user ID and other needed information, which is rather small, and avoid using the database for this completely. The client would just pass around the blob (like the string in the previous paragraph) without needing to know what it contains, and only the web services would know how to decrypt it.
This should eliminate the need for the database to store the session information and would make the whole process a good bit simpler. With the database you have to worry about cleaning up old sessions and timeouts and so on.
So my question: is passing around sensitive data from service to service via client considered safe and acceptable? Is it possible to do this in a way that would eliminate worry about the client tampering with the data? What encryption algorithms would be good to use?
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'm going to create my own project, and i have some difficulties with technology selection. I will have client application(windows forms) and web service. Data exchange between clients will be only by using this web service. Data will be like image stream,so I don't know which technology to use. I started to look at WCF, but i don't know a lot about it.

View 4 Repliesi have a website in our office which is a School. the website is an enrollment website which is available view internet, where the users (students) access the website to enroll almost simultaneously, select their subjects and schedules, etc.
this website is developed by someone who is no longger employed here. regular problem of the website is in times of enrollment, the students is experiencing slow processing when ever thay try to view/edit their information, subjects, etc. which are all in the database. a proposal was made and we have agreed to develop a new system that should run faster than the old system. access sql database to do Select/Update/Insert in the fastest way possible.
When calling Response.Cookie.Add(new HttpCookie("MyCookie", "objValue")); where does the cookie saved? on Client Machine or Server Machine?
EDIT:if saved in Client Machine, how can I read it from javascript then? I tried this kind of script.
function getCookie(c_name) {
var i, x, y, ARRcookies = document.cookie.split(";");
for (i = 0; i < ARRcookies.length; i++) {
[code].....
I cannot get the cookie that I saved from code behind. When I look into the document.cookie object, it is just an empty string.
Scenario:On Page_Init() on code behind. I create a cookie using Response.Cookie.Add(new HttpCookie("MyCookie", "cookieValue"));.
On Client side, I'm trying to read the cookie saved from code behind on page load using the snippet above, but it returns undefined
I'm working with ASP.Net web services and am having a problem with a long-running process that takes about 5 minutes to complete, and it's timing out. To fix this, I was able to set the executionTimeout on the server's web.config to 10 minutes, and then set the .Timeout property on the Web Service object to approximately 9 minutes. Now, I'm worried that this may possibly cause some other web service calls to sit there for 10 minutes before they time out rather than the previous 90-100 seconds. I know the default on the client side is 100 seconds, but wasn't sure if updating the server's timeout setting would affect this.
Bottom line is - Is it safe to update the server's timeout setting to a long amount like 10 minutes, and rely on the default timeout on the client, or could this end up causing some problems?
I'm trying to develop a new application for multiple users. the main idea is that one user talks and the entire users (who logged in ) could hear him (1 way).
How this can be made? how can i transfer voice from one client to multiple clients in live?
Note that my clients are mobile users (Android, IOS and Windows phone) and the server is .NET.

MSDN "ASP.NET Delegation" article tells:
1) "When you configure to use a particular account as the process identity, ASP.NET attempts to delegate that account. If it is a local account that is identical (including password) to a local account on a remote machine, delegation is possible. If such an account does not exist on the remote machine, to the network it appears as the Windows anonymous account (NT AUTHORITYANONYMOUS LOGON). In addition, delegation is also possible if the account is a domain account that has access to the remote machine, in which case it uses the domain network identity of that account."
The same frequently repeated story as in case of manually/interactively accessing remote computer (server resource) in workgroup - it is necessary to create local account with the same username, the same password. But why?
If a workgroup Windows client process cannot access resources on server machine without having duplicate of such (local) account on target machine already pre-created,does it mean that client (process, machine, or user) can access server resources only by/after having logged (opening logon session) into server machine? Or, how to understand that such access is impossible without having corresponding duplicate local account on server machine?
The same MSDN "ASP.NET Delegation" article tells:
"NetworkService account. It behaves the same as the System account. This account possesses the network credentials associated with the machine account (domainnamemachinename) in the domain of which it is a member"
Does not any Windows have accounts ((NT AUTHORITYNETWORK SERVICE)? as well as many other common pre-built accounts? Why are they installed (before any joining to domain) but cannot be used for remote network access and client identification ? And what is identity used when the process from workgroup Windows under identity ((NT AUTHORITYNETWORK SERVICE) accesses a remote server?

We have an UpdatePanel that is showing a gridview with loads of data in it. We have loads of well written sprocs that don't take very long, BUT we have a few horrible ones that take ages.
We do intend to rewrite them but in the interim we have put the ADO.NET commandtimeout up to 180s. The scriptManager.AsyncPostBackTimeout is set to 240s. We want to handle this on the serverside. One of the reports still fails (it's got a couple of nested cursors in it - someone who hasn't had SQL lesson 101 from me!).
Half the time, the nice error timeout message is shown using server side handling of the command timeout. The problem is that the other half of the time the commandtimeout doesn't seem to fire.

I want to send a file by converting it into binary file to the client end and then it should be read by javascript which again I am passing to the OCX method.(like my OCX method accept only the binary data so i have to transmit binary data from server side to client).
