Feeling I am doomed

Question

Good morning, I am sending this mail seeking advice for my career. I have been working in web development using asp.net and SQL Server for the past 8 years but I am a single developer in my company and the projects I do are not that big, so, I got the feeling that I am outdated and not up to the standards of web development anymore. I am trying to study online courses and read recent news but due to the fact that I am not within a team i feel separated from the developers environment. I thought of quitting for another company but i found that I can't stand against powerful candidates in my field. Now I am starting to lose interest and just sticking to the routine of doing what I know without trying to update myself as I am feeling its now useless. Thanks in advance for your help.
I want to add that i don't have any Microsoft certificates .

Answer 1

Dear Null and Character String cant Add by this way if you want to add numeric then you should do like this


TextBox3.Text = (Convert.ToDouble(Convert.ToString(textBox1.Text)) + Convert.ToDouble(Convert.ToString(textBox2.Text))).ToString();

in Text Change Event

it will convert zero if null exist



you can also chaeck by TextBox1.TextLenght  = 0  then zero value

Answer 2

Yes, It would raise error as you are trying to add "" (empty text) with your 2/3 texbox's values(integer).

Just initialize (default Text value) all your textboxes with 0 or 0.00

So, no matter how many inputs you give, it will not give you error.
