[@mrcsnbr]

Thank you Sir, so much appreciate. I was almost losing it because everything was working well but the decimal operations. I followed exactly what you did and I was getting an error whenever I tried to do an operation with a decimal number. Turned out that since my system operator is in Spanish I needed to change the dot " . " for a comma " , " lmao, it's working well now. I'm definitely going to check more of your videos.

​ @Paul Oamen Hello! Could you explain what does this code actually mean?
Is this a standart solution for error from "MyForm.h"?
Sorry i couldn't understand
​using namespace System;
using namespace System::Windows::Forms;

[STAThreadAttribute]
void Main(array^ args) {
Application::EnableVisualStyles();
Application::SetCompatibleTextRenderingDefault(false);
CalculatorTut::MyForm form;
Application::Run(% form);
}

[@mohamadmaleki3026]

Dear Paul, thanks a lot for the video. I've done all exactly the way you explained but at time 11:14 it throws Error LNK2001 and LNK1120. How should I handle these errors? thanks

[@PaulOamen]

Try again

[@yorkrogers990]

hola Mohama,,creo que me paso a mi tambien. y fue porque puse "Main" en lugar de "main" y Configuration:Active(Debug) at 2:20 goodluck.

[@marioc3810]

Hi Paul, In parallel to my work i have been learning C++ for like 2 years, but i would like to comment on something, following your videos i can make my calculator to work with several changes that are omitted in the video, like the name of the display is different and the button "." is also different, but as a beginner i can figure it out how to solve it, but i realize that i'm just doing copy and paste, is it possible that you make a video or point me where i can find the secrets of visual studio, i mean where all these precooked code come from, what they mean... i want to understand the logic behind of what you are doing you know..... do you know the saying
"Give a Man a Fish, and You Feed Him for a Day. Teach a Man To Fish, and You Feed Him for a Lifetime"
Your videos really teach real and practical applications.
Thanks so much.
