Text.ConvertStr(Text, Text, Text) Method

  • Άρθρο

Version: Available or changed with runtime version 1.0.

Replaces all chars in source found in FromCharacters with the corresponding char in ToCharacters and returns the converted string. If the length of the FromCharacters parameter and the ToChars parameter are different, an exception is thrown. If the parameter FromCharacters or the parameter ToChars is empty, the source is returned unmodified. Each element in source is only converted ONCE a double-replacement cannot happen.

Syntax

NewString :=   Text.ConvertStr(String: Text, FromCharacters: Text, ToCharacters: Text)

Note

This method can be invoked without specifying the data type name.

Parameters

String
 Type: Text
The string that you want to convert.

FromCharacters
 Type: Text
The characters that you want to replace. This function is case-sensitive.

ToCharacters
 Type: Text
The new characters with which you want to replace the FromCharacters. This function is case-sensitive.

Return Value

NewString
 Type: Text
The input string with the converted characters.

Remarks

The characters in the FromCharacters parameter are replaced by the characters in the ToCharacters parameter.

If the lengths of the FromCharacters and ToCharacters strings are not equal, then a run-time error occurs.

If either the FromCharacters or the ToCharacters strings are empty, then the source is returned unchanged.

Example

var
    OriginalString: Text[30];
    FromChars: Text[30];
    ToChars: Text[30];
    NewString: Text[30];
    Text000: Label 'Do you want to leave without saving?';
    Text001: Label 'lws';
    Text002: Label 'LWS';
    Text003: Label 'The original sentence is\\: %1';
    Text004: Label 'The sentence is converted to:\\ %1';
begin
    OriginalString := Text000;  
    FromChars := Text001;  
    ToChars := Text002;   
    NewString := ConvertStr(OriginalString, FromChars, ToChars);  
    Message(Text003, OriginalString);  
    Message(Text004, NewString);  
end;

The first message window shows:

The original sentence is:

Do you want to leave without saving?

The second message window shows:

The sentence is converted to:

Do you Want to Leave Without Saving?
