Only allow digits in the TextBox (use a mask and / or an event handler) ... This avoids the whole question of whether it is an integer, float, negative, etc.

Hi, I have inherited UserControl to MySubControl to add a common core base for a new set of controls.
However, when events are added in VS2013 designer, MyControl the events attached to MYControl do not fire.
i.e.
this.MyControl = new MySubControl .MyControl ();
this.MyControl .Load += new System.EventHandler(this.MyControl );
Can anyone point me in the right direction..
Thanks
public class MySubControl : UserControl
{
}
public partial class MyControl : MySubControl
{
}

Um...that's some odd code. Does it compile?
Normally, you would add the handler by pointing at a method - not at an instance.

A 'Load EventHandler in an inherting UserControl, created at design-time, or run-time in code ... will work.
A 'Load EventHandler in a UserControl named 'MyControl which inherits from a UserControl, 'MySubControl will fire after you have created an instance of 'MyControl by:
1. design-time: drag-drop from ToolBox to a Form or other Container Control
or
2. run-time: you have created an instance in code
And you then execute your program.
To help you beyond this, I think we need more details from about what you are doing.
Please show code that you are using that demonstrates what you describe.
Are you only creating instances of 'MyControl ?

A user control still needs to be added to a Window's .Controls collection before it will display (in a Window) and fire the .Load event.

That's an excellent point to stress, Gerry !

Thanks for the response guys, I have sorted it now.
I had a sendmessage in an area of code which seemed to block all events from firing back. Moved to somewhere more sensible.

Hi Gautham,
Nice to see your article on Selenium webdriver using C#
I have gone through one of your article-(Automated Testing Of Web Pages Using Selenium-Web Driver).In that i have few doubts
1.How to add the all(chrome,iedriver exe) files folder to enviornment variables in my local machine.Please take a look and help me on this issue.
2.I have written n ran code like below,getting error as source code not found.please see the screen shot also.
public static IWebDriver InitializeDriver()
{
//if (WebDriver == null)
// {
//string DRIVER_PATH = @"C:\Web drivers\IEDriverServer.exe";
string browser = Convert.ToString(ConfigurationManager.AppSettings["BrowserType"]);
switch (browser)
{
case "ie":
WebDriver = new InternetExplorerDriver(@"C:\Web drivers\IEDriverServer.exe");
return WebDriver;
//break;
//case "FF":
// WebDriver = new FirefoxDriver(DRIVER_PATH);
// break;
case "chrome":
WebDriver = new ChromeDriver(@"C:\Drivers\BrowserDrivers\chromedriver");
return WebDriver;
//break;
default:
WebDriver = new FirefoxDriver();
return WebDriver;
//break;
}
// }
}

I haven't written an article on Selenium so your message obviously isn't directed at me. I'm pretty sure none of the regulars here have either.
When you have a question about an article, the correct place to ask your question is on the forum at the end of the article. Don't post in a random place hoping that the author will stumble across it.

Hello,
Apologies for what surely is a very basic question. I'm new to C# and need to write some easy functions for an application we use at work. This application uses a special DateTime as it needs to accommodate unknown date parts, e.g. UNK/May/2015. Ideally I would like to know the difference in months between two dates, but for a start I'm happy with just the year difference (the year will always be known). I've written the following function which throws no errors but it always returns 0. I can see while debugging that StDt.Year and EnSt.Year are integers with the correct year, but it doesn't seem to calculate the PackYears. Any help is greatly appreciated!
[DesignerFunction("Calculates the pack years")]
public static int fnCalculatePackYears(
[DesignerParameter("Start Date (date)")] PFDateTime StDt,
[DesignerParameter("End Date (date)")] PFDateTime EnDt)
{
int PackYears = 0;
int StDtYr = StDt.Year;
int EnDtYr = EnDt.Year;
PackYears = (EnDt.Year - StDt.Year);
return PackYears;
}
Thanks in advance!
Nicole

Without knowing more about your PFDateTime class, we can't really help you. Except to say why are you reading the year values into variables, and then ignoring them?
So start with the debugger.
Put a breakpoint on your return statement, and run your app in the debugger. When it hits the breakpoint, it will stop. Look at the values of PackYears (it'll be zero if you are right), at StDtYr and EnDtYr I'm just guessing that they are the same value...and probably zero.
So look at the inputs, and see what they contain.
We can't do any of that for you - we can't run your code!
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

Then you should also be able to see the result of the calculation (what are the two years' values?). Are you sure this is the exact code you are debugging?

Good afternon
I am saepul from indonesia
i have question
where my question is
how sintax make automatic number where that automatic number

thanks very much

Where are you getting your counter number from? The reason I ask this is because if you rely on a program to maintain a running total then you are probably going to have problems if the application crashes and restarts - you'll get duplicated numbers and it seems likely that this isn't what you want. Is the number meant to be an identity field in a database?

STOP SHOUTING.
Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalization if you want to be taken seriously.

Hello,
I want to return a string color based on these 4 calculations.
X = 25%
5.0% >= X >= -5.0% blue
+15.0% >= X > +5.0% and -5.0% > X >= -15.0% yellow
+25.0% >= X > +15.0% and -15.0% > X >= -25% green
X > +25.0% and X < -25.0% red
I am having trouble forming the logic. Thank you for the help.

Off the top of my head - untested! 
int x = 25;
Color c = GetColor (x);
public Color GetColor
(int x)
{
if ((x <= 5) && (x >= -5))
return Color.Blue;
if ((x <= 15) && (x >= -15))
return Color.Yellow;
if ((x <= 25) && (x >= -25))
return Color.Green;
return Color.Red;
}

Are you planning on writing one, or looking for someone to do so?
If the first, then you should investigate how to keep a list in a database, and how to fetch an item from it. If the second, then you are on the wrong site.

It's an API. As long as there's an internet connection, you can call the API. You do realise we aren't going to pre-roll the code for you don't you?
