Implementation of the string comparison feature for the C typing exercise program 10

It's really hard to say casually if you haven't done this. You can try using the comparevalidator control, but this control compares the values of two text boxes, one character at a time. You need to write your own ** transformation.

Paste ** directly to you.

procedure : tobject);

varv_strtmpold,v_strtmpnew:string;

v_index,v_errcnt:integer;

beginv_strtmpold := trim(;Gets read-only text box characters.

v_strtmpnew := trim(;Get input text box characters.

v_errcnt := 0;Count of error characters.

Iterate through the read-only textbox characters and compare strings one by one.

for v_index := 1 to length(v_strtmpold) do

beginif length(v_strtmpnew) >= v_index then

beginif v_strtmpnew[v_index] begininc(v_errcnt);

end;end else

begininc(v_errcnt);

end;end;

if v_errcnt > 0 then

clred;

showmessage('The character entered is incorrect, and the number of characters is incorrect' + inttostr(v_errcnt));

end else

beginshowmessage('The submission was successful');

end;end;

Very well implemented... Text box key events can be handled.

Is the list not instantiated and an empty object?

c Generally used vs development (full name: Microsoft Visual Studio) is generally the 2010 version.

Practical things to do by yourself.

It feels like string processing. OpenFile component. The last one is displayed.

It's the property of the form. These are the most straightforward properties to modify. Modify the string.

There is basically nothing to say. It is not recommended that you go directly to someone to ask for **. You look at the corresponding widget properties.

It's all basic stuff.

You can help you with the outline, complete the full text of the text, and handle the format by yourself.
