Web Forms :: How To Get Proxy Settings From Client's Browser
Jan 11, 2011
Is that possible to get the proxy settigns right across several browsers, such as IE, firefox or safari from Asp.net? According to someone it is impossible because ASP.NET runs on the server, and therefore has very limited access to the client's settings.
But having said that, HttpBrowserCapabilities is able to retrieve plenty of information from a client machine, so i thought there is must a way to also retrieve the proxy settings on client's browser/s.
Is there a way to get the precise client's operating system, coz the HttpBrowserCapabilities.Platform property doesn't give me the precise client's operating system.
I tried the below code for getting clinent ip address. Request.UserHostAddress; or
Request.ServerVariables["REMOTE_ADDR"]; or
Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
If the request coming from IE it will work file, but in the case of Mozilla Firefox it shows the proxy ip address. I am getting the sam ip addres from different machine if the request from mozilla firefox.
In an article I have read "A web browser can be named as proxy server. As safari, chrome, mozilla".But proxy server is like a an intermediatary btween the clent and server know?
Is there a way to change the browser settings for IE8, directly using the .net code.
I had developed an application, which has a functionality to upload a file from My Networks. I browse the file and try to upload it. It works fine in IE6. But in IE8, instead of displaying me the path of the file, it gives C:/Fakepath. When I enable the security setting of browser "include full path while uploading the file from the server", it works fine and gives me the whole path.
I created a very simple webService using the VS2008 template. i am planning to use Ajax call for the webService.when i try to open my webservice in IE browser using following link to see the Javascript proxy, it return blank page.[URL]
I was wondering if there was a way to detect a browsers or client displays settings so that I could format a page accordingly? What I would like to do is create two separate styles that could be loaded dynamically depending on a persons settings.
Say one person with an older computer has their display settings set to 800x600, that persons page would be formatted to best accommodate that screen resolution and another person viewing the same page at a much higher resolution would have it formatted differently to best accommodate them.
Im calling the new popup window from gridview like
[Code]....
In the AddTargetPopUP.aspx ,I have button Call "ADD".When i click the add button it'll insert datas into database.I want to reload the parent gridview after insert into the database and want to close the popup.
I have this in the system.web section of web.config:
[Code]....
Elsewhere, I have this code:
[Code]....
There's nothing clever going on in the dataset - it's a simple SELECT. Everything works fine when my browser has the default settings. But, as soon as I change the browser language to cy-GB, the line of code above fails with:
[Code]....
I'm probably missing something obvious, but can't see why changing the language in the browser causes a [seemingly] unrelated data retrieval operation to fail.
I have created a user control that has a gridview. During binding I set some common properties like height and width. To do so, I have created public properties. I have created the public property so that user can also set the height and width themselves. But if user didn't specify then I use my defaults.
My problem is that user settings are always overridden by my default settings. I want to set the default values as the control is rendered on the page and then if user apply his settings then it shold override. Which event/method is best on user control to jandle such scenario? Where should I write the code to call my default settings so that it is first thing that happens? What is the user control life cycle?
I have a simple web page as below named eventviewer.aspx. I host it in a server under the default website and when i browse it from the INETMGR it opens and displays teh events.
But when i try to open it from another machine, by reqyestiung the page, it just shows the heading and not the grid. Can you provide some inputs??
I 'm implementing my version of "ShareThis" in my webpage.How can i get the client's browser displayed address with Asp.NET?I am little confused with this one since the url to share...1) is created with URL rewriting2) contains Greek characters.
I need to get client stats for browser (not full long description but short names, generally firefox,ie6,ie7,ie8,safari,chrome,opera and mozilla). Client resolution and OS ie. Windows Vista, Ubuntu .
I want local/Client machine ip address, for that i have written below code. but this code gives me Application server address where my web site is hosted. where as i wanted client machine IP from where my web site is getting accessed. so if my website accessed from 10 different machine in that case i want 10 different IP address of those machines.
What should i do if the javascript was disabled on the client browser ?
Should I call the server side ? and how could i do such a thing if it is possible ?
I have a web page, and I am using JQuery ajax, and I'm calling the server side using the webMethod attribute, so what should i do if the client browser disable Javascript ....
I'm looking for possible ways for sending files from browser to server. One obvious way is using form with enctype='multipart/form-data'. I wonder if there are other ways than this.
The reason I ask you this question is this file uploader: http://aspnetajax.componentart.com/control-specific/upload/features/core_features/WebForm1.aspx
It's not flash based, but it sends the file in a way that it gives you a progress bar, but when you send a file with form with enctype='multipart/form-data' the whole file will be send to the server so you can't actually show a progress bar of uploading process.
This thing has just came to my head and I wanna share it.Note : I could easily test it but I am being lazy here to see if anybody has ever experienced something like that before.Let's assume that I have a web site which built-in membership structure of asp.net has been implemented on. What will happen to asp.net membership if the client browser blocks cookies? Does framework throw an exception when a user tries to log in or do something else?
Have some problems with client side validation (using RequiredFieldValidator, RegularExpressionValidator, CustomValidator with client side validation logic). It seems that WebForm_DoPostBackWithOptions is not fired or causes unhandled exception that makes the form to do the postback regardless it's valid or not.
I tried using a ValidationSummary, hiding it if javascript is supported:
Every thing works fine on Chrome with disabled javascript on my laptop, but not on my Android phone. The problem is that on the phone Javascript is not disabled, it's enabled, and correctly hides the ValidationSummary, but does not perform client side validation for some reason that i can't understand (no developers tools on Android browser :(( ).This is very frustrating! :(
Assume a simple aspx data entry page in which admin user can upload an image as well as some other data. They are stored in database and the next time admin visits that page to edit record, image data fetched and a preview generated and saved to disk (using GDI+) and the preview is shown in an image control.
This procedure works fine for the first time however if the image changes (a new one uploaded) the next time the page is surfed it shows previously uploaded image. I debugged the application and everything works correct. The new image data is in database and new preview is stored in Temp location however the page shows previous one. If I refresh the page it shows the new image preview. I should mention that preview is always saved to disk with one name (id of each record as the name).
I think that is because of IE and other browsers use client cache instead of loading images each time a page is surfed. I wonder if there is a way to force the client browser to refresh itself so the newly uploaded image is shown without user intervention.
In asp.net website, i am using crystal report. My question is very generic i.e. How it is possible to display client side (browser) date and time?
Actually in my case our website is going to hosted at India, while that site is used by user's at SWEDEN.
Now the problem is that when user request for report then it is displaying server side date time because i have used PRINTTIME control of crystal report. But user should have date and time of their PC. because that time is basically a report generates date time.
We have many different clients, and each client can have multiple user accounts.Right now, we have user settings set up on the ASP project, and a WinForms application can see these settings, depending on which user logs into the winforms application. They are specific to the user. I want to make them specific to the client, so users can be in "groups" by their client, and all users in the group would see/update the same settings.
We have an ASP.NET web application and it's hosted using IIS 6.0, in the app we have these several javascript and css files located in a folder, and for performance sake (according to YSlow) we set the folder content expiration header to 1 year. Everything worked just fine until recently when we deployed the latest build to the server, in which we had made some changes to those javascript and css files. For some reason after the deployment some of our end users don't see the latest changes when they connected to the app, even after they cleared the cache in IE. We have also restarted the IIS on the server and the problem still remained. When I went into the IE Temporary Internet Files folder on one of these machines I saw the files were still the older version and not the latest one, I had to manually delete the files from the Temporary Internet Files folder then they were able to see the latest changes. I'm baffled by this, how come only some users who couldn't see the changes but some others do (without having to do anything by the way), and how do I make sure that for future releases we won't have to do anything like what did (manually deleting the cached files)? For now I disabled the Content Expiration option in IIS for these files but I would like to know if there is a way that I can enable the content expiration (to help performance) but at the same time making sure when the files are updated, the latest version will be used for the end user (instead of the cached version)?
