Why will this C# code Not work?

[DarkBlade2117]

 

All the .Text are underlined

  	decimal mySalesAmount;
            decimal myTaxAmount;
            decimal myTotalAmount;
            mySalesAmount = decimal.Parse(mySalesAmount.Text);
            myTaxAmount = decimal.Parse(myTaxAmount.Text);
            myTotalAmount = mySalesAmount * myTaxAmount;
            myTotalAmount.Text = myTotalAmount.ToString("c");

These are all lined up btw in Visual Studio. Basically, mySalesAmount is what a user paid for say a fast food bill, then the myTaxAmount is what the Tax of said user is. I then I need to multiply these to get the Tax in which the user paid, which is going to be displayed in myTotalAmount. I understand that it says myTotalAmount, I then need to add the myTotalAmount and the mySalesAmount to get the REAL myTotalAmount, I changed the GUI up a bit inbetween code to make it more user friendly. Keep in my this is one of my first C# codes, talk to me like a 6 year old.

Hey man, I would love to help you but am really confused on what you are trying to accomplish on lines: 

 mySalesAmount = decimal.Parse(mySalesAmount.Text);
 myTaxAmount = decimal.Parse(myTaxAmount.Text);

I can tell you the reason its red is the decimal data type does not contain a "Text" property or field, but not sure how to help you since it appears you are just attempting to set a variable to itself here. 

 

Even if this did execute it would be equivalent of a = 1 then a = a.

I think he's trying to parse in the values entered into the textbox

To get the sales amount and tax amount.

 

Though I may be doing it all wrong. Basically, my goal is to put in a number and a tax amount then calculate what the tax will be and what the total amount would be.

 

I have all my buttons in there, so far I only have the GUI created and the Clear button which basically just clears all the text boxes.

Ah, do you know what he is using for UI, windows forms, WPF, some other libs?

Visual Studio 2012 Express? Or am I thinking something else?

Sadly no, but from the codes and the use case description. It seemed like he was using a textbox

Ohh yeah I am using Text Boxes.

So visual studio is your IDE, or editing environment for future reference.

Ok so textbox class is part of the Windows Forms libraries. Can you post your Entire .CS file contents here. I have some ideas on what may be your issues but I need to see more to know.

This correct?

I think I get what's your problem

 

The variable names you've chosen for the variables that you've created looks to be conflicting with the textbox name. 

You're using mySalesAmount.Text to parse in to mySalesAmount . The names of your textbox and viarable are conflicting. 

 

Use a different name for your textbox or variable.

That would be a problem

Wait.. Like I said, very new to C# and apparently we were supposed to start out with console commands ( though never happened ) so this whole GUI thing is confusing.

What variable? I know the textbox name though..

Basically, what I am trying to do is take say I type like 63 into the mySalesAmount textbox, I want to be able to multiple that by whatever is entered into the myTaxAmount , say it be 6.25 for example, I then want that to be entered into the myTotalAmount Textbox. Total Amount will be changed to Tax Charged and then I want to be able to take the mySalesAmount ( 63 ) + the myTaxAmount for 6.25% * 63 = ( Whatever ) is displayed in the new myTotalAmount

Rename one of your variables. They are too similar and VS in confused as to what you are referring to.

 

so for the textbox name. Maybe mySalesAmountText.

I'll tell you what, if you can tell me whether you want a console application or a GUI application I can do a quick screen capture and you can watch me do it, that way you can see exactly what the process should be.

You cannot use the same name for your variable and textbox, it will conflict. Rename either your textboxes or your variables. 

 

Variables are this: 

 

decimal mySalesAmount;
            decimal myTaxAmount;
            decimal myTotalAmount;

OK, I screen capped myself doing it, I added it to my YouTube Channel. To say thanks you can subscribe

 

Link... It is currently processing but should be ready in a minute.

Ohhh so I got it

 decimal mySalesAmount;
            decimal myTaxAmount;
            decimal myTaxPaid;
            mySalesAmount = decimal.Parse(mySalesAmountText.Text);
            myTaxAmount = decimal.Parse(myTaxPercentText.Text);
            myTaxPaid = mySalesAmount * myTaxAmount;
            myTaxPaidText.Text = myTaxPaid.ToString("c");  

So now my problem is the bottom right is underlined, myTaxPaid.ToString ect, that is meant to display the end calculation in the myTaxPaid text box. I then need to take that number in the myTaxPaidText textbox + the mySalesAmountText textbox and to display in the myTotalAmountText textbox

Did my video clear up your questions?

Yes it did, So many people try and tell me to go out and figure it out on my own, and yeah maybe at one point I should though for learning showing me how to do it from start will show me how I can figure out or attempt to do it by myself in the future. Thanks so much

I agree, being a self taught professional I went through the same thing. This may have inspired me to broaden my YouTube channel to include beginner programming tutorials, do you think you/others would like to see more videos like what I made for you?

I would love it, Going to have some hard times in this class. This program which I've been trying to figure out for 5 hours is only 33% of the assignment itself. I also need to create a Car Cost Comparison program in which I obviously compare two cars.

Purchase Price

Annual Repair Cost

Annual Insurance Cost

First calculation being 1 year total fuel cost and

then the second one being 5 years for total of all cost including Purchase Price, 5 year annual fuel cost, 5 years of repairs and 5 years of insurance all in one calculation... http://imgur.com/a/I68NF basically..

Maybe it wouldn't be so hard if I weren't taking 5 other classes and already get a few hours of homework from them also and being on a time frame can be troublesome.

I'll come on tomorrow if I need any help with this at all, hopefully I can get through it.
