"0" : "") + currentMinutes; 9: currentSeconds = (currentSeconds < 10 ? "0" : "") + currentSeconds; 10: // Choose either "AM" or "PM" as appropriate 11: var timeOfDay = (currentHours < 12) ? "AM" : "PM"; 12: // Convert the hours component to 12-hour format if needed 13: currentHours = (currentHours &

If you have web services and want to call the web service from your c# code, you can try to use this code example. The code example uses HttpWebRequest to create a request for the web service.  Code Behind HttpWebRequest request = (HttpWebRequest)WebRequest.Create(<web service address>); request.Headers.Add("SOAPAction", "http://tempuri.org/" + <web service method>); request.ContentType = "text/xml;charset=\"utf-8\""; request.KeepAlive = false; request.Timeout = 300000; // - in millisecond. (5 minit) request.Method = "POST"; request.Credentials = CredentialCache.DefaultCredentials; byte[] byteArray = Encoding.ASCII.GetBytes(<data you want to send to webservice>); request.ContentLength = byteArray.Length; Stream s = request.GetRequestStream(); s.Write(byteArray, 0, byteArray.Length); s.Dispose();

Most of the websites and web applications must have an error handler. Some programmers might question what are the error handler should have on one website. Below is the basic error handler that you need to set in the website : Page Not Found - 404 Internal Server Error - 500 Access Denied - 403 The above error page must-have in one website. This is because when the application catch error, the end-users will see asp.net designed page without detailed error information that might not user friendly for the end-users. To handle these errors, all you need to do are two things which are Create the above error page and set in the web.config file in asp.net. Below is an example of a setting in the web.config file. Web.Config <configuration> <system.web> <customErrors defaultRedirect="~/500.html?" mode="RemoteOnly"> <error statusCode="404" redirect="~/404.html" /> <error statusCode="500" redirect=&quo

Most of the web applications nowadays are complex applications that maybe have more than 50MB source code to deploy on the server and it will lead to a long compilation time around 3-10 minutes depends on the server resources. Some will say, it still ok to wait for the compilation since it only happens for the first time. What about require to change the source code with a very minimal code of line.? Like one line only.? Do you still love to wait 3-10 minutes? The answer is no. But how to avoid this situation. It is simple, just one line of configuration on the web.config will help to fasten compilation code (Just in time compilation). The answer is put : optimizeCompilations="true" as an attribute on the compilation element in the web.config file.

This is an example of how to force the current HTTP Context Response to download files. Before that, you need to set a path/folder in your web application to store files that you just created or pre-set the file to download. In ASP.NET this is the way to set a path. Since we can use the tiddler("~") symbol to referring to the root with a virtual path set from IIS. string pathFile = Server.MapPath(Request.ApplicationPath); Force download method : string pathFile = Server.MapPath(Request.ApplicationPath); Response.AddHeader("Content-Type", "application/octet-stream"); Response.AddHeader("Content-Transfer-Encoding", "Binary"); Response.AddHeader("Content-disposition", "attachment; filename=\"" + yourfilename + ".csv\""); Response.WriteFile(pathFile + yourfilename + ".csv"); Response.End();

Recently I have developed some modules to upload the file to the server. In my code, I have an update panel and also the multiview. Somehow the upload not working. So I thought I was not set the full postback for the upload process in the trigger section under the update panel. But actually, the full postback was set correctly. So I wonder, why the upload not working.  So I start to investigate my code, and luckily I found the solution. The solution  I just need to set enctype attribute at the form and value  multipart/form-data. This is the code I use. protected override void OnInit(EventArgs e) { base.OnInit(e); Page.Form.Attributes.Add("enctype", "multipart/form-data"); } Hopefully, this simple solution helps someone.

This is example in asp.net how to detect client browser and version. The method used in this example can work after copy paste in the Visual Studio. Aspx Code <br /> <h5> <asp:Literal ID="Literal1" runat="server"></asp:Literal> </h5> <p> &nbsp;</p> <p> &nbsp;</p> Code Behind  private string SAFARI_CODE = "Safari"; private string CHROME_CODE = "Chrome"; private string IE_CODE = "IE"; private string IE_LONGCODE = "Internet Explorer"; private string GECKO_CODE = "Gecko"; private string OPERA_CODE = "Opera"; protected void Page_Load(object sender, EventArgs e) { Literal1.Text = GetBrowserClass(true); } /// <summary> /// Gets the browser specific CSS class name. /// </summary> /// <param name="includeVersion&q

Sometimes you want to avoid bot from crawling the page with sensitive information like phone number and email address, so you need to have a method to detect either the request is a visitors or bot.  This code snippet shows how you can determine the request is a crawler or not. Code Behind  /// <summary> /// Returns whether browsing device is search engine crawler (spider, bot). /// </summary> public bool IsCrawler() { if (HttpContext.Current != null) { HttpRequest currentRequest = HttpContext.Current.Request; return (currentRequest.Browser != null) && currentRequest.Browser.Crawler; } return false; } You can put this method under a static class and call it from the Global.asax file.
