• Integrate ClickOnce update in a setup

  - by Erick

  As recent decision in my team we decided to deploy a software we develop for some time now in ClickOnce. Previously it was deployed with a merge module in a setup project. We had in mind to actually deploy the ClickOnce setup/updater in the web server setup. The problem here would not exactly to integrate it but to make sure to limit the human work to integrate it. Normally I guess it would be necessary to "add - file" and select the folder containing the setup.exe + publish.htm + application files + .application, but I fear that for each time we publish a new version to the hard drive we have to update the setup project as well. Would someone have some insight to help that ? (especially to not have to add the program_[version] folder inside application files that is created each time a new publish is done).

• Does an HttpHandler require an aspnet_isapi.dll mapping

  - by DEH

  Hi, If I configure (via web.config) an httphandler to handle all .gif requests for a specific folder, is it absolutely essential for me to map .gif requests to aspnet_isapi.dll in IIS? Is there any other way of ensuring that the .gif http request will be handled by aspnet_isapi.dll? I have a server configured where the virtual dir that contained the .gif-aspnet_isapi.dll mapping has been deleted, but the .gif requests are still being passed to the handler. Anyone know how this might be being done, and where the setting might be lurking? Thanks

• SQL Server and iPad app interaction

  - by Phanindar

  I have to write an app for iPad that would take data from SQL Server and post it to the iPad. I looked up on this over the Internet and found that i have to write a web service to expose the data from SQL server using ASP.NET. I did an app previously in android that would take data from my dropbox a/c and display it to the user. I made use of the drop-box api available. I was wondering if anything like that exists for SQL? Also, i have to code in Obj-C for the iPad, so how will i write ASP.NET code? I have more doubts. Thanks in advance.

• Color blindness: Are you aware of it? Do you design for it?

  - by User

  I'm curious whether many of us who do design or take design decisions have ever heard of this problem. I'm aware there are dangerous color combinations, like green + red. This is probably one of the most popular cases of color blindness. If you have green text on a red background and vice versa some people won't see anything. I've also seen in practice that green text on a blue background was not seen by one guy. What other color compositions should be avoided, and how often these cases are to be expected? Let us make some ranging by encounter probability who has the numbers. Addition: I've just remembered one very bad example that causes problems to just about everyone - blue text on a black background. It's unreadable for all intents and purposes. Never could understand what could possibly compel a web master to use this color combination...

• how use ASP.NET_SessionId cookies to check timeout for 2 different web applications

  - by user553858

  Hi All I am developing 2 web applications based on "ASP.NET_SessionId" cookies to check session timeout and also to logout : protected void Session_Start(object sender, EventArgs e) { if (Context.Session != null) { //check the IsNewSession value, this will tell us if the session has been reset if (Session.IsNewSession) { string cookie = Request.Headers["Cookie"]; // Code that runs when a new session is started if ((null != cookie) && (cookie.IndexOf("ASP.NET_SessionId") >= 0)) { if (Request.QueryString["timeout"] == null || !Request.QueryString["timeout"].ToString().Equals("yes")) Session.Abandon(); Session.Clear(); Response.Redirect("Login.aspx?timeout=yes"); } } } } This works fine for my first application. When implementing the same logic for the 2nd application when I press logout in one application, the second application is redirected to the login page. How can I fix this? Best regards

• Can't access my files in ASP.NET web site

  - by jumbojs

  I'm having a very difficult time. I am running windows 2008 server, I have an Able Commerce site using ASP.NET with C#. I'm writing an automated task that will ftp some xml files down into a local directory on our web server and then the program parses the xml file and saves information to our database. The problem, once I save the files to our local directory, my program has no access to the files. The NETWORK SERVICE user permissions isn't being inherited by the xml files so my program can't do anything with them. I can manually change the permissions, but this wouldn't be automated and won't work. How can I get this to work? help please, it's very frustrating.

• Issues in Ajax based applications

  - by Sinuhe

  I'm very interested in developing Ajax based applications. This is, loading almost all of the content of the application via XMLHttpRequest, instead of only some combos and widgets. But if I try to do this form scratch, soon I find some problems without an easy solution. I wonder if there is some framework (both client and server side) to deal with this issues. As far as I know, there isn't (but I've searched mainly in Java world). So I am seriously thinking of doing my own framework, at least for my projects. Therefore, in this question I ask for several things. First, the possible problems of an ajax based development. Then, I'm looking for some framework or utility in order to deal with them. Finally, if there is no framework available, what features must it have. Here are the issues I thought: 1 - JavaScript must be enabled. Security paranoia isn't the only problem: a lot of mobile devices couldn't use the application, too. 2 - Sometimes you need to update more than one DIV (e.g. main content, menu and breadcrumbs). 3 - Unknown response type: when you make an Ajax call, you set the callback function too, usually specifying if expected response is a javascript object or in which DIV put the result. But this fails when you get another type of response: for example when the session has expired and the user must log in again. 4 - Browser's refresh, back and forward buttons can be a real pain. User will expect different behaviors depending on the situation. 5 - When search engines indexes a site, only follow links. Thus, content load by Ajax won't "exist" for who doesn't know about it yet. 6 - Users can ask for open a link in a different window/tab. 7 - Address bar doesn't show the "real" page you are in. So, you can't copy the location and send it to a friend or bookmark the page. 8 - If you want to monetize the site, you can put some advertisings. As you don't refresh entire page and you want to change the ad after some time, you have to refresh only the DIV where the ad is. But this can violate the Terms and Conditions of your ad service. In fact, it can go against AdSense TOS. 9 - When you refresh an entire page, all JavaScript gets "cleaned". But in Ajax calls, all JavaScript objects will remain. 10 - You can't easily change your CSS properties.

• What alternatives are there for asp.net forms authentication?

  - by Eytan Levit

  Hi, We are developing a web app that will have a pretty complex user and permission system. The general idea is that we have 3 levels of security: a simple user - that can only access basic data that is in a data repository a manager - that can open up data repositories a superuser - that can open up repository factories. each repository contains various data types(text, images, etc etc). We are looking for authentication methods that will allow us: 1. Scalability. 2. Customization. 3. To create permissions that will effect the GUI + deny access to certain pages. 4. To create predefined roles - that will allow for easy setup of new users. 5. To create custom roles for specific users - allowing them permission sets that are different from the predefined roles. Thanks in advance

• Web page with embedded .NET control in IBM WebSphere 6.1

  - by Borat

  Hello, I have very simple web page with embedded .NET control in it via the <object> tag. The problem is that when I deploy it to an IIS server it works fine (the .NET control is shown). The same is for the Apache server. But when I deploy it to the WebSphere server I get the html but the .NET control does not appear. Probably it is some kind of a server configuration issue, but I cannot figure it out. I would appreciate any suggestions. Best regards!

• GWT Strength compared to other framework??

  - by Noor

  One of the main strength of GWT is to code in java and everything gets compiled and is loaded by several browsers through gwt deferred binding?? Apart from this, i.e. working only on a single code base, do GWT has any other advantage compared to other existing framework?? Edit: I'm trying to say why should we use gwt and not another framework?? What is there in GWT that makes it special for web application development?? What GWT makes for us and another framework or toolkit don't do?? As i said above GWT makes deferred binding which is a plus, so I wanted what other things it do that makes it special and unique??

• Connecting a PHP front-end to a back-end java service

  - by christopher-mccann

  I am currently using various back-end services and I want to use PHP to simply query these services and perform the final page construction. These services could be coded in any number of programming langauges such as Erlang, Java, Python etc. However I am unsure of the best way to actually interface the back-end services with the web app. Requests to these services would be both synchronous and asynchronous. Would I use something like SOAP or JSON-RPC?? Any help greatly appreciated.

• Understanding character encoding in typical Java web app

  - by Marcus

  Some pseudocode from a typical web app: String a = "A bunch of text"; //UTF-16 saveTextInDb(a); //Write to Oracle VARCHAR(15) column String b = readTextFromDb(); //UTF-16 out.write(b); //Write to http response In the first line we create a Java String which uses UTF-16. When you save to Oracle VARCHAR(15) does Oracle also store this as UTF-16? Does the length of an Oracle VARCHAR refer to number of Unicode characters (and not number of bytes)? And then when we write b to the ServletResponse is this being written as UTF-16 or are we by default converting to another encoding like UTF-8?

• .NET Web Service Proxy is adding special characters in XML

  - by xkingpin

  My web service proxy seems to be adding special characters like "*" and "#" etc. within the xml nodes. My proxy created lists using arrays of objects. I am trying to create a generic list and then doing list.ToArray() to set the proxy MyProxyObject[] object. Is this the cause of the problem I am having? I plan on running fiddler on the request later but it is over SSL and I do not have access to the URL at the moment. Here is an example of the XML that is generated: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> * <soap:Body> o I'm a little concerned because the special characters are even occuring before the array nodes

• Sending out 20,000+ emails with asp.net

  - by Kyle

  I am writing an application that will need to send a massive amount of emails to our students who will be selected from our database (each email will be personalized to the extent that will include their name, course of study etc...so needs to be sent one at a time). I could do this looping over an SmtpClient, but I'm afraid that with the numbers I'm trying to send, I'll ultimately run into timeout issues or my thread being killed because of lack of machine resources. At this point I'm just looking for suggestions of a better way to handle this, or if looping over SmtpClient is an ok solution, how I should go about handling it to prevent what I posted above. Would a web service be a better alternative? Please advise, TIA

• How do I send an email from my webpage?

  - by Jordan S

  I am not a web developer but I do have a lot of programming experience in C# and Windows forms programming. On our company webpage my boss wants me to put in a textbox where visitors can submit a comment and press a submit button and that comment will be sent to an email address. Right now, our website uses just plain old html, no php or javascript or anything like that. I am wondering what is the simplest way to accomplish what I need? Can someone point me in the right direction? The website is hosted on an Apache server so I won't be able to use aspx.

• I need an efficient protocol between webservices that are more or less supported by all major langua

  - by corgrath

  Hey all. I am looking for a fast and efficient protocol that can be used between different web services to send text-data (not binary data). Doesn't matter if the protocol is binary or text base. Some conditions: I has to be more "efficient" than normal XML which adds a lot of extra data and the tools to read/write is too heavy It has to be "supported" by most major languages, meaning it cannot only be available for one specific language. At the moment, both Java and PHP have to be able to talk to each other using this protocol. I have already looked at: XML - which I am currently using. Hessian 2 -which works perfectly in Java, but the PHP-support is out of date JSON -the different between JSON and XML is only minor Any suggestions are welcome!

• Setting ownership/permissions for symfony2 and other web projects

  - by Handonam

  I've been very confused as to how to set permissions and user/groups for my sites. It is particularly one of my weakest suits My curent problem is that I often find myself running into a situation where if i view a particular page, it won't have permissions to write to cache or logs. At this point I'll set the ownership towards apache. Then, in other cases, if i try to run internal scripts, for example, I can't write to these cache/log files because i set them for apache. Currently, my symfony2 files are all registered to me as a part of staff (Handonam:Staff). I've seen various people creating groups such as www-data, apache, etc, and using users such as theirselves (e.g. Handonam) or www as a part of those groups. So my question is: For symfony2 and other web projects, what's generally the best setup for user/group setup so that both apache and myself can interact with these files, while maintaining decent security?

• The risk of granting to IUSR* NTFS permissions on a folder on the server

  - by vtortola

  I have two web applications that must share a file in the server file system. Both apps are inside of "Inetpub\wwwroot". The file cannot be accessed freely from outside, so it is in a folder out of "Inetpub". I have granted full NTFS permissions to the user "IUSR_whatever" (is the user that runs IIS in anonymous requests) in that folder. The folder has only that file, and has no other use. It works so far :) But, what is the risk? what should I be afraid of? As I see it, as long the folder is out of the "InetPub" cannot be accessed, and as long the apps don't have any security flaw like "path traversal" or server side code injection, it should be safe enough.... But I'm always keen to be wrong :) What do you think? May the file or even the server itself get compromised because of this? Thanks.

• Rewriting URL in AJAX application

  - by Artem Moskalev

  I am making a simple online application. I have a navigation bar with a few buttons and one "div" into which all the new contents will be loaded dynamically i.e. when I click "About", it will load the page parts into the "div" without reloading the whole page with .load() function. The problem is: what if I need to give a link to the Documents section of my web site, or the user wants to store this kind of link, the url is not rewritten when browsing my site. when the user stores the default link it will always link him to the default "Home" part. How can I rewrite the URL and what is the most correct way to do this?

• What is the most efficient way to list all of the files in a directory (including sub-directories)?

  - by prometheus

  I am writing a servlet which will examine a directory on the server (external to the web container), and recursively search for certain files (by certain files, I mean files that are of a certain extension as well as a certain naming convention). Once these files are found, the servlet responds with a long list of all of the found files (including the full path to the files). My problem is that there are so many files and directories that my servlet goes extremely slow. I was wondering if there was a best practice or existing servlet for this type of problem? Would it be more efficient to simply compile the entire list of files and do the filtering via js/jquery on the client side?
