Displaying multicoloured text in a label

Question

Basically, I want a label to display the result in a different colour . At the moment the program simply outputs a message along with a variable, what i want to do is have the variable in a different colour to the text. E.g. my variable is called InterestToBePaid of the type float, the current code is: lblInterestToBePaid1Year.Text = "The Total Interest You Have To Pay For One Year Is: " + InterestToBePaid; How would I change InterestToBePaid in to a different colour ?

Ah right, ok then, I'll try it and let you know how it goes

OK, try this: private void btnCalculate_Click(object sender, EventArgs e) { try { Amount = float.Parse(txtAmount.Text); InterestRateInPercent = float.Parse(txtInterestRateInPercent.Text); LoanDuration = float.Parse(txtDurationInYears.Text); // Calculates the Interest for one year InterestToBePaid = InterestRateInPercent / 100; InterestToBePaid = InterestToBePaid * Amount; // Display result in label lblInterestToBePaid1Year.Text = "The Total Interest You Have To Pay For One Year Is: "; lblInterestToBePaid1.Visible = true; lblInterestToBePaid1.Text = "" + InterestToBePaid; // Calculates the Total Interest InterestToBePaid = InterestToBePaid * LoanDuration; // Displays result in label lblTotalInterestToBePaid.Text = "The Total Interest You Have To Pay Is: "; lblTotalInterestToBePaid1.Visible = true; lblTotalInterestToBePaid1.Text = "" + InterestToBePaid; // Calculates Total Amount to be paid TotalAmountToBePaid = Amount + InterestToBePaid; lblTotalAmountToBePaid.Text = "The Total Amount You Have To Pay Is: " + TotalAmountToBePaid; // Caclculates Monthly Repayments MonthlyRepayments = TotalAmountToBePaid/LoanDuration/12.0f; lblTotalMonthlyRepayments.Text = "Your Monthly Repayments Are: " + MonthlyRepayments; // Calculates the Monthly Repayments for one year MonthlyRepayments = MonthlyRepayments * 12.0f; lblMonthlyRepayments1Year.Text = "Your Monthly Repayments For One Year Are: " + MonthlyRepayments; } catch (Exception exc) { MessageBox.Show(exc.Message); } } A couple of points on this: 1. It's meaningless to talk about the 'Total amount for one year' here, so I've removed this code altogether: // Calculates the Total Amount for one year TotalAmountToBePaid = Amount + InterestToBePaid; lblTotalAmountToBePaid1Year.Text = "The Total Amount You Have To Pay For One Year Is: " + TotalAmountToBePaid; 2. We're doing this in a very simplistic way because we're charging the same interest every year even though capital is being repaid throughout the term. The total repayments are therefore higher than they should be. However, if you haven't been taught the formula for working out mortgage repayments properly, you can hardly be expected to figure it out yourself so this will have to do for now.

For some unknown reason, I'm getting an extraction failed error : "A RAR archive could not be decompressed entirely". Could you try again or just post the code.

Hey, I need some more help, I don't think my forumulas are correct, would you mind fixing the code and sending it back please? If you have the time, I would do it myself but my brain is hurting from all the maths and I've been working on this all day, I'd appreciate the help.

Lmao, I'll keep that in mind ;) thanks once again for your help :)

Yeah I've got the "C++ : A Beginners Guide" by Herbert as well, I tried to learn C++ at first but I got to the part about arrays and my mind just fried lol, so I thought it would be best to start with an easier language to learn, and yeah it mentions all the books he's wrote, wish I was like that lol, would be amazing

Vulpes · Answer

Yes, Herb is a world authority on the 'C family' languages as he's written books on C, C++, C# and Java. He has even been involved in the standardization committees for C and C++.

Umar Anjum · Answer

Thank you :) damn, you certainly know a lot about programming, by the way, the Java book that i ordered came today, I've started reading it, still on the first few chapters where it talks about the history of Java and that, Herbert Schildt is just epic lol, I have so much respect for people that know more about something than I do, and yes that includes you as well lol.

Place two labels next to each other. Set the Text property of the first label to: "The Total Interest You Have To Pay For One Year Is: " and the Text property of the second label to the expression: InterestToBePaid.ToString(). You can now set the colors of the two labels to whatever you want.
