Hi there,
I need some help, again.
How to save the result to the log file in desired conditions by checking the data entered in the textbox?

For example, how can I ensure that the data is saved in the log file only when a value between 0 and 100 is entered in the text box, and that the user is warned when any data is entered or a character is written outside of mentioned values?

In the example below, I was able to save the data entered in textbox, but I could not check the data type.
I'll be happy if you can help me.
Yours truly,

Here is the example: https://we.tl/t-uS1ItW0oRb

Hey,

So basically you only need to save input from user in range of 0...99 into the file, and everything different from that shouldn't be saved + user should be warned that entered data is incorrect?

That's true,
If I can check the data entered in the textbox, it can already save sample code, but I was not able to integrate the data control in to the sample code.

Best regards,

Well, you needed to use stuff I've made in this thread.

Try this code:
Code
BMAP *pointer_tga = "pointer.png";

STRING *name_str = "Click to Enter Value Here!";
STRING *enter_value_str = "Click to Enter Value Here!";
STRING *error_msg_str = "You need to enter a number from 0 to 99!";
STRING *data_saved_msg_str = "Data was successfully saved into the log file.";

function input_name(); 

PANEL *input_pan = 
{
	layer = 10;
	bmap = "textbox.png";
	on_click = input_name;
	flags = SHOW;
}

TEXT *name_txt = 
{
	layer = 11; // just above the textbox panel
	font = "Calibri#30";   
	string(name_str);
	flags = SHOW | CENTER_X | CENTER_Y;
}

// receives a STRING and position (num) of a character in that STRING
// returns a single character as a STRING
STRING *get_next_char(STRING *src_str, int num)
{
	if(!src_str)
	{
		return NULL;
	}
	
	if(num > str_len(src_str))
	{
		return NULL;
	}
	
	STRING *temp_str = "";
	str_cpy(temp_str, src_str);
	str_trunc(temp_str, str_len(src_str) - num);
	str_clip(temp_str, num - 1);
	
	return temp_str;
}

// returns TRUE (1) if string is numeric
// otherwise returs FALSE (0)
var is_numeric_str(STRING *src_str)
{
	if(!src_str)
	{
		return false;
	}
	
	int i = 0, j = 0, res = true;

			}
			
			res = true;
			break;
		}
		
		if(res == false)
		{
			break;
		}
	}
	
	return res;
}

// returns TRUE (1) is string's length is zero

var is_empty_str(STRING *str)
{
	if(!str)
	{

	}

	{

	}
}

function input_name()
{
	str_cpy(name_str, "   ");

					file_close(filehandle);

				}
			}
			else // not numeric ? then show error message
			{
				error(error_msg_str);
				str_cpy(name_str, enter_value_str);
			}
		}
	}
}

function mouse_startup()
{
	warn_level = 6; // make sure to show all errors
	fps_max = 60; // limit fps to 60
	
	mouse_mode = 4; // this will take care of mouse_cursor/mouse_pos stuff

Thank you @3run laugh That was great solution! This is exactly what I want to do.

Thank you again, @3run. I just want to ask because I'm curious about. If the user provided a condition between 0 and 150 (instead of 0 to 100 value), how could we do that?

I would change 2 to 3 in this part
Code
// we can also check for the range here
// if it's more than 2 characters, then we are out of the range
if(str_len(name_str) > 2)

So we will allow to enter value which is made out of 3 characters.
Then I would convert string into the variable using str_to_num.
And at the end I would check if this variable is higher than 150 or not. If it is, then give error, if it is not then save data.

Best regards!

Hi,
I think that when you work with numbers is better to use numerical variables instead of strings.

Here goes a simple implementation with the use of 'key_any' and 'key_lastpressed'

Code
function num_edit (var *_ptr_num, var _max) {
	var _old_value = *_ptr_num;
	var _last_pressed = key_lastpressed;
	while(1) {
		if(key_any) {
			if(key_lastpressed != _last_pressed) {
				_last_pressed = key_lastpressed;
				switch(_last_pressed) {
					case 1: // esc
						*_ptr_num = _old_value;
						return;
					
					case 14: // back space
						*_ptr_num = floor(*_ptr_num / 10);
						break;
					
					case 28: // enter
						return;
					
					default: // any other key
						if(_last_pressed > 11) // from 1 to 0 keys -> from 2 to 11 scancodes
							break;
						var _res = *_ptr_num * 10 + (_last_pressed - 1) % 10; // 11 = scancode of 0 character
						if(_res > _max)
							break;
						*_ptr_num = _res;
				}
			}
		} else {
			_last_pressed = 0;
		}
		wait(1);
	}
}

// --------------------------------------------------

function main () {
	static var my_num = 20;
	num_edit(my_num, 150);
	
	while(1) {
		DEBUG_VAR(my_num, 100);
		wait(1);
	}
}


Salud!
