Symbol counter

Post by Identis » Tue Jan 17, 2023 10:50 am

Hello,

is it possible to make in dialog window symbol counter? I want to make field where can type max 160 symbols (sms) and counter how many symbols left.

Thanks in advance.

I would have thought so, simply by comparing the existence of a symbol in user input to a list of variables. It would get quite complicated if you didn't want to allow duplicates though.

What kind of symbols?

These two articles will help you learn the basics of Dialogs :

Article 1.
Article 2.

Once you've digested those, here's something very basic to get you started, but typing one single character as a proof of concept :

Code: Select all


Dialog>Dialog1
object Dialog1: TForm
  Left = 1073
  Top = 214
  HelpContext = 5000
  BorderIcons = [biSystemMenu]
  Caption = 'CustomDialog'
  ClientHeight = 417
  ClientWidth = 1170
  Color = clBtnFace
  Font.Charset = DEFAULT_CHARSET
  Font.Color = clWindowText
  Font.Height = -28
  Font.Name = 'MS Sans Serif'
  Font.Style = []
  OldCreateOrder = True
  ShowHint = True
  OnTaskBar = False
  PixelsPerInch = 240
  TextHeight = 32
  object Label1: TLabel
    Left = 24
    Top = 216
    Width = 114
    Height = 32
    Caption = 'Symbols'
    Font.Charset = DEFAULT_CHARSET
    Font.Color = clWindowText
    Font.Height = -27
    Font.Name = 'MS Sans Serif'
    Font.Style = [fsBold]
    ParentFont = False
  end
  object Label2: TLabel
    Left = 24
    Top = 264
    Width = 120
    Height = 32
    Caption = 'CountLeft'
    Font.Charset = DEFAULT_CHARSET
    Font.Color = clWindowText
    Font.Height = -27
    Font.Name = 'MS Sans Serif'
    Font.Style = [fsBold]
    ParentFont = False
  end
  object Label3: TLabel
    Left = 24
    Top = 88
    Width = 427
    Height = 32
    Caption = 'Type a symbol then click "check"'
    Font.Charset = DEFAULT_CHARSET
    Font.Color = clWindowText
    Font.Height = -27
    Font.Name = 'MS Sans Serif'
    Font.Style = [fsBold]
    ParentFont = False
  end
  object Edit1: TEdit
    Left = 21
    Top = 144
    Width = 242
    Height = 40
    TabOrder = 0
    Text = '@'
  end
  object MSButton1: tMSButton
    Left = 285
    Top = 136
    Width = 150
    Height = 50
    Caption = 'Check'
    TabOrder = 1
    DoBrowse = False
    BrowseStyle = fbOpen
  end
end
EndDialog>Dialog1


AddDialogHandler>Dialog1,MSButton1,OnClick,DoClick
Let>TheString=!"£$%^&*()[email protected]><;:'
Len>TheString,LenString

SetDialogProperty>Dialog1,Label1,Caption,TheString
SetDialogProperty>Dialog1,Label2,Caption,%LenString% left

Show>Dialog1,res

 
SRT>DoClick
  GetDialogProperty>Dialog1,Edit1,Text,TheTxt
  StringReplace>TheString,TheTxt,,TheString
  SetDialogProperty>Dialog1,Label1,Caption,TheString
  Len>TheString,LenString
  SetDialogProperty>Dialog1,Label2,Caption,%LenString% left
End>DoClick

I didn't mentioned something about dublicates. They can type everything they want.
symbols I can get with Length> ,but I don't know how to show counter and update it on every symbol (numbers, letters and etc.) typed.

I've adjusted it to allow duplicates, and to continuously watch the input with no button clicks required. For this example I just used abcde... instead of symbols just so it was clearer to see. You'll see at the beginning where I've edited out the symbols line. You should be able to replace that with your list of symbols.

This uses regex to find the match, and then removes the matched characters from the original string. I'm not a regex expert and acquired that from online sources - so if you need to edit the regex to something more impressive (particularly if any of your symbols need to be escaped) I won't be able to help there.

But with regards to the Dialog and it's functionality, I think this does what you're looking for.

Always happy for others here to improve upon my suggestions :

Code: Select all

//Character Match String
Let>TheString=abcdefghijklmnopqrstuvwxyz1234567890
//Let>TheString=!"£$%^&*()[email protected]><;:'
Len>TheString,LenString

Dialog>Dialog1
object Dialog1: TForm
  Left = 1073
  Top = 214
  HelpContext = 5000
  BorderIcons = [biSystemMenu]
  Caption = 'CustomDialog'
  ClientHeight = 417
  ClientWidth = 1170
  Color = clBtnFace
  Font.Charset = DEFAULT_CHARSET
  Font.Color = clWindowText
  Font.Height = -28
  Font.Name = 'MS Sans Serif'
  Font.Style = []
  OldCreateOrder = True
  ShowHint = True
  OnTaskBar = False
  PixelsPerInch = 240
  TextHeight = 32
  object Label1: TLabel
    Left = 24
    Top = 216
    Width = 162
    Height = 46
    Caption = 'Symbols'
    Font.Charset = DEFAULT_CHARSET
    Font.Color = clWindowText
    Font.Height = -40
    Font.Name = 'MS Sans Serif'
    Font.Style = [fsBold]
    ParentFont = False
  end
  object Label2: TLabel
    Left = 24
    Top = 264
    Width = 120
    Height = 32
    Caption = 'CountLeft'
    Font.Charset = DEFAULT_CHARSET
    Font.Color = clWindowText
    Font.Height = -27
    Font.Name = 'MS Sans Serif'
    Font.Style = [fsBold]
    ParentFont = False
  end
  object Label3: TLabel
    Left = 24
    Top = 88
    Width = 484
    Height = 32
    Caption = 'Type your symbols from the list below'
    Font.Charset = DEFAULT_CHARSET
    Font.Color = clWindowText
    Font.Height = -27
    Font.Name = 'MS Sans Serif'
