Error in parsing Convert.ToDouble or double.Parse for decimal values in C#

I found that one of my client's application showing "0,00" for pricing column of his application, and found that it works find on my pc. Once I traced the error, I found that it fails when parsing price like "1500.00" with Convert.ToDouble or double.Parse. The reason for that is, the particular client using Finnish currency format, which is like "1500,00". As you see the difference is they use "," instead of "." for decimal separation. If you want to convert decimal (money) values in string format, which will universally work in every where, you have to use following code snippet.

            string pricetext = "5535.25";
            string[] parts = pricetext.Split('.');
            double price = Convert.ToDouble(parts[0]);
            if (parts.Length == 2)
            {
                dec = Convert.ToInt32(parts[1]);
                price += (dec * 0.01);
            }

CSS text-overflow ellipsis in the beginning of the the text - Left Ellipsis using CSS in a Flex box

Image
Problem: If you want to have css text overflow ellipsis in the left (beginning of the text), there is no straight forward solution to get it working in all browsers (especially in Safari). There are several CSS tricks that you will end up only working few browsers. It will be further difficult, if you are trying to achieve this in flex container. Solution: Combining few ideas found in the stack-overflow, manged to get it working in most of the browsers including safari. ".cont" is flex box and either you can set a width to it, or can inherit the width from parent container element. .ellipsis:after { content: ""; background-color: white; color: transparent; position: relative; z-index: 2; min-width: 100%; display: inline-block; min-height: 1rem; } .ellipsis { direction: rtl; display: inline-block; width: calc(100% - .1em); white-space: nowrap; overflow: h

Selenium With .Net

Recently I had a chance to work with Selenium framwork. It is pretty easy to intrgrate automated testing into .net with Selenium. Also for project like web site scrapping and automated posting, can be easily developped with few lines of code. Following code lines will automate a web site login with use of selenium framework. ISelenium selenium = new DefaultSelenium(seleniumServer, port, browser, website); selenium.Start(); selenium.Open(ConfigLoader.Configurations.LoginPageUrl); selenium.WaitForPageToLoad((ConfigLoader.Configurations.WaitingTime * 1000).ToString()); selenium.Type("ctl00_PageContent_UserName", ConfigLoader.Configurations.UserName); selenium.Type("ctl00_PageContent_Password", ConfigLoader.Configurations.Password); selenium.Click("ctl00_PageContent_OKButton__Button"); selenium.WaitForPageToLoad((ConfigLoader.Configurations.WaitingTime * 1000).ToString());

Handling Exit Event of Console Application in C#

Do you wan to do something on the exit event of Console Application. .Net framework does not provide such direct event to do that. You can use following workaround to have that kind of event in your application.         [STAThread]         static void Main(string[] args)         {             HandlerRoutine hr = new HandlerRoutine(Handler);             SetConsoleCtrlHandler(hr, true);             GC.KeepAlive(hr);          }         public static void DoOnAppExit()         {                   //Do something......         }         #region Handle App Exit         static Boolean Handler(CtrlTypes CtrlType)         {             // A switch to handle the event type.             switch (CtrlType)             {                 case CtrlTypes.CTRL_C_EVENT:                 case CtrlTypes.CTRL_BREAK_EVENT:                 case CtrlTypes.CTRL_CLOSE_EVENT:                 case CtrlTypes.CTRL_LOGOFF_EVENT:                 case CtrlTypes.CTRL_SHUTDOWN_EVENT:
