✅ Help with creating shapes on a windows form app

I have created a windows form app to display shapes on a bitmap, my circle function works fine but my rectangle will work regardless of the text I put in, for example..

circle 40

circle 40

will draw a circle with a radius of 40 as it should

bingbong 30,20

bingbong 30,20

will still draw a rectangle even though the string is incorrect

else if (CommandSplit[0].Equals("rectangle") == true) ; /// RECTANGLE FUNCTION

{
    try
    {
        ParameterSplit = CommandSplit[1].Split(",".ToCharArray());

        int width = int.Parse(ParameterSplit[0]);
        int height = int.Parse(ParameterSplit[1]);
        ErrorHandlingWindow.Clear();

        MyCanvass.DrawRectangle(width, height);
        Refresh();
        return;
    }

    catch (FormatException)
    {
        ErrorHandlingWindow.Text = FormatExceptionErrorMessage;
        return;
    }
    catch (IndexOutOfRangeException)
    {
        ErrorHandlingWindow.Text = IndexOutOfRangeExceptionMessage;
        return;

    }

else if (CommandSplit[0].Equals("rectangle") == true) ; /// RECTANGLE FUNCTION

{
    try
    {
        ParameterSplit = CommandSplit[1].Split(",".ToCharArray());

        int width = int.Parse(ParameterSplit[0]);
        int height = int.Parse(ParameterSplit[1]);
        ErrorHandlingWindow.Clear();

        MyCanvass.DrawRectangle(width, height);
        Refresh();
        return;
    }

    catch (FormatException)
    {
        ErrorHandlingWindow.Text = FormatExceptionErrorMessage;
        return;
    }
    catch (IndexOutOfRangeException)
    {
        ErrorHandlingWindow.Text = IndexOutOfRangeExceptionMessage;
        return;

    }

if (e.KeyCode == Keys.Enter)
{
    String Command = SingleCommandLine.Text.Trim().ToLower();
    CommandSplit = Command.Split(' ');
    {

        if (CommandSplit[0].Equals("circle") == true)

        {
            try
            {
                ParameterSplit = CommandSplit[1].Split(",".ToCharArray());

                int radius = int.Parse(ParameterSplit[0]);
                ErrorHandlingWindow.Clear();



                MyCanvass.DrawCircle(radius);
                Refresh();
                System.Diagnostics.Debug.WriteLine(CommandSplit[0]);
                System.Diagnostics.Debug.WriteLine(CommandSplit[1]);

                return;


            }
            catch (FormatException)
            {
                ErrorHandlingWindow.Text = FormatExceptionErrorMessage;
                return;
            }
            catch (IndexOutOfRangeException)
            {
                ErrorHandlingWindow.Text = IndexOutOfRangeExceptionMessage;
                return;

            }

        }

if (e.KeyCode == Keys.Enter)
{
    String Command = SingleCommandLine.Text.Trim().ToLower();
    CommandSplit = Command.Split(' ');
    {

        if (CommandSplit[0].Equals("circle") == true)

        {
            try
            {
                ParameterSplit = CommandSplit[1].Split(",".ToCharArray());

                int radius = int.Parse(ParameterSplit[0]);
                ErrorHandlingWindow.Clear();



                MyCanvass.DrawCircle(radius);
                Refresh();
                System.Diagnostics.Debug.WriteLine(CommandSplit[0]);
                System.Diagnostics.Debug.WriteLine(CommandSplit[1]);

                return;


            }
            catch (FormatException)
            {
                ErrorHandlingWindow.Text = FormatExceptionErrorMessage;
                return;
            }
            catch (IndexOutOfRangeException)
            {
                ErrorHandlingWindow.Text = IndexOutOfRangeExceptionMessage;
                return;

            }

        }

this is my circle function which works correctly

Have you tried debugging to see what's going on / being passed through when your code's running? Might also help to see the full class

hugheselite•7mo ago

I have and I honestly still can't figure it out :/ i'm going to paste the full class also, it had a character limit on disc one moment

SinFluxx•7mo ago

$paste

else if (CommandSplit[0].Equals("rectangle") == true) ; should've spotted it from your initial message, you've got a semi colon at the end of your if statement

hugheselite•7mo ago
