Hi!
Im a beginner at C# programming. Im studying a class in this language and unfortunatly im stuck:(

The assignment is about a Cinema system.
Userimputs a value-----> if valid it appears on the listbox with person name, ticket price and total revenue for the day.

the above i have no problem with!
The assignment needs me to have two classes. And in this second class
I need to convert the textbox price value into a double value.
so far no problem!

In this second class im requierd to implement a code that checks if the users
code fullfills the minlimit value which is 0 and that it is under the maxLimit
which i have put to a thousand. code looks like this:

C#

public static bool GetDouble(string StringToConvert, out double dblOutValue, double minlimit, double maxlimit= 100) {
 
    bool ConvertedDoubleNumber = Double.TryParse(StringToConvert, out dblOutValue);

    if (dblOutValue == maxlimit)
    {
        MessageBox.Show("Please enter a valid number ", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
    }

I assumed that the users imput would get saved in dblOutValue but apperantly it does not get saved.

Kepp in mind that this is only a small code. I have a mainform since this is a forms application which has a bunch of code.

The only relevant thing to note here is that a code gets sent to the second class(utillityclass) and gets converted to a double value by suing tryparse.

I need that double value to issue a max/minlimit and for that i need help.
This requiers overloading and I tried that but the variable dblOutValue
does not exist in the other method since i cant use the same inparametes.
if i only use maxlimit and minlimit i cant get it to work.

Please help!
Regards
Peter!

Hi Peter,

your goal should be easy to achieve, but I think you mixed a few things.
Hope my code sample below is doing what you what you want to achieve.
It simply returns a Boolean "false" if "input"-value is < 1000.

C#

//Set Variables to save values after invoking GetDouble() In your MainForm
bool IsMaxLimit = false;
double out_value;
yes = GetDouble("646", out out_value, 100);
MessageBox.Show(IsMaxLimit.ToString() + " " + out_value);

C#

public static bool GetDouble(string StringToConvert, out double dblOutValue, double minlimit, double maxlimit = 1000)
        {
            //I didn't recognized where you want to check the conversation in your code
            //bool ConvertedDoubleNumber = Double.TryParse(StringToConvert, out dblOutValue);

            if (dblOutValue < maxlimit)
            {
                return false;
            }
            else
            {
                return true;
            }
        }

Hope it works for you.

Best Regards
