How to Make a Calculator in C# Windows Form Application Part-2

[@enihgilead1427]

'Tis the best tutorial I found... after a long, long search on the net! Congratulations, bro, for sharing; helped a lot!

[@madjayhawk]

I haven't finished it yet but will. It is working perfectly so far. Thank you for taking the time to produce this for us newbies. It really helps me to see how a practical problem is put together.

[@ledizzy2634]

Have you finished it now?

[@李春鹏-g2l]

Very helpful to me. Thank you so much for making this video. Just one comment: If we press the equate button and want to continue to press an operator button. It will "performClick" the equate button again. So, I suppose to add one line at 18:16: if (labelCurrentOperator.Text != "") // The label shows something, which means the last action is not pressing the equate button. button15.performClick();

[@csstudent355]

Your video helped me a lot about my homework. Thank you.

[@aakashakku5]

Thank you SIR. Hope I become good in programming.

[@papiabiswas5633]

Very effective video. It helped me a lot to finish my assignment. Thank you so much for the nice video.

[@adrianv.1636]

Great videos!! Thank you sir for your awesome explanation, I followed every step and I have my calculator working 100%! Thanks

[@reinie6279]

Nice tutorial, thank you. I converted this Form app into a WPF app (with XAMLcode) successfully (its slightly different). Next step is to implement the keypad using this app (works much faster).

[@khingkhing7085]

so did you do successfully implement it ?

[@spitfire3280]

Great tutorial! Very clear, logical and easy to follow.

Well done, ProgrammingKnowledge. Well explained and this lesson is a very good basic to go forward in programming in C#

[@thewatcher1776]

Klaudia Mueller please learn the basics first (operarors, datatypes, variables definition, scopes, oop, design patterns) then you'll see the right way...

[@rahadulhaq6387]

Thank you so so very much That was really very easy to understand as a beginner❤❤

[@myself8709]

Thncs for this label statement it is really working..i was fixing it since yesterday

[@Moffe1A4]

Hey! Very good and helpful tutorial. I just want to add something i had a problem with. I always get this exception error when i try to use decimal numbers! "An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll" how i fixed this was very simple. Change the text "." that represent a comma in your design form to a ",". and make sure to change the "." in your comma handler to "," too i.e the if statement. Thanks again :)

[@Arghandevol]

Mohammed Al-Jumaili I have same problem. That not solved my problem. Weird

[@EmrikWan]

Thanks my dude, I was getting really confused for a second there.

[@SPOG17]

[@helucz4772]

Thanks So much for this 2 Awesome helpful videos it seriously helped me alot do my own calculator and from now ill use my own calc instead of the normal one! also my friends were surprised Thanks!

[@sudheerb4919]

very informative n useful for beginners thank you so much

[@UsmanKhan-ny6bu]

very smooth knowledge but i want to ask one thing.. when we perform the operation the result value goes into the label box.. but when we do more calculations.. the label box just showing the first result and current operation.

[@tanjibontu6656]

Thank you so much. You really teach so well.

[@elunatsciencetime]

it really helps me tnx bro

[@kanchanamedapati6416]

Thank you. These two video's were very helpful .

[@ninamohamed490]

Hey I'm at 10:43 and I've followed every little detail and I checked twice still my label idk why is showing the word label 1 after I ran it and it shows nothing else and when I click + or any other Operation it doesn't work , plz help

Great job. Thank you very much for making these two videos

[@anileybekele]

good job, appreciate it can do substring, to cancel each number

[@hasanaslan2688]

Thank you for your work. But there is a problem. You didn't add anything about multiple operations. For example; 12+12=24 but when we get this result, we can click at another number button to continue addition. But at this work, we can't get the exact numbers for the multi operation

[@ravipala8087]

Yes bro .same prblem

[@GusioonYt]

Thank you brother!

[@RaiseOfMaster]

Hi, Thank you so much for this tutorial, But I have got a problem: when I do 1+5 then click equal (=) and then do any operation instead of doing the 6 with any other number it makes the 12. Please Help!

[@rena1826]

Great tutorial, helped me with some of my problems ! But when i click 3+3 = *display* 6 but when i click + again, it straight away adds the 6 which display 12 (*3 + 3 + 6*). It does not allow me to input a 2nd number .

[@abdullahajeebi]

Same

[@isak1496]

@@abdullahajeebi same, u found a solution yet?

[@lukechopper22]

Try this solution, making sure to ignore the ‘InitializeComponent’ method as it is almost definitely going to be incompatible with the components on your calculator’s own GUI in addition to taking the time to rename the relevant methods - i.e., ‘button5_Click’, ‘button6_Click’, ‘button16_Click’, etc. - so that they match up with the corresponding names of the click event listeners that you have previously endowed your own button components with: pastebin.com/raw/1B9AFkkT

[@ilikecod4584]

i just added "resultValue = 0;" at the end of the code under "labelCurrentOperation.Text = "";" and it worked fine.

thank yo uso much. i have completed the tutorial and it goes very fine.. its kind of nosebleeding hahaha

[@siferuk]

Nice one but shouldn't you use decimal instead of double since double is not precise. For example try 0.09 * 100 then 0.09 * 99.999999

[@Dotto19]

Thank you brother

[@dcrdcrnkl1]

Thanks so much it really helped me

[@klsar1]

this is incomplete. After you have pressed = to get the final number, you can still attach new figure to it by pressing any numerical button. Example - after you have done with 20 + 30 = 50, you can attach any number to the figure 50 to make it 504 or 50434 or any string that begins with 50. This is wrong.

[@thewatcher1776]

klsar1 yea. try to use another if statement and you're good. :D

[@aeternae1646]

what kind of if statement

[@benhurex32]

hi sir can you give a tutorial on how to calculate loan with interest? :)

[@harald921]

+Perfect .Copy Multiply with percentage. For example if you have a loan of 1000$ and there's an 10% interest. int loanAmount = 1000; float interestAmount = 0.10; // loanAmount = loanAmount + (loanAmount * interestAmount); // Simplified, but you get what I mean

[@christiandanielmagallanes9287]

+Harald Kanin Good answer. I would suggest to change loanAmount to a double variable to ease future decimals as result.

[@narminsky]

thank you very very very much

[@ax-crazy]

Thanks

[@nakaharaaki6486]

When i tried to follow this tutorial then i found a little issue. When i created the bool then i could not use number-buttons cuz they were not working and nothing appeared in textbox. To mąkę it appear i had to add to instruction for number-buttons "if" phrase "isoperationperformed = true". Then i could not use numbers like 10 or something like that cuz only one number appeared like: when i wanted to write 12 then IT appeared like 1 and then changed on 2.

[@bahy66]

please do this 0 - 6 - 5 or 0 * 5 * 3 it will be error how to treat.

[@setonmautin7630]

Please can you explain why my decimal is not responding to the oerator.. eg. 2.5 + or any other operator keep crashing,,i get a message with input string was not in a correct format

[@carmeloparan5141]

Thanks Bro. :) Very Helpful.

[@Squidiyyy]

not sure why, but it will not let me use the code "button.text" just wont work no explanation, everything is exactly identical to his code. Anyone know?

[@erdelysimon]

Because it's button.Text

[@maryamafzal6948]

sir my . and any operator are not working along with each other means if i like to add 3.3+2 then complier shows error before writing '2' or 2.3+ error 5.6* error 1.1- error ... so how to recover it?

Please help me. when I press a character other than + it always points to +. is there any solution?
