===Attributes===
<big><syntaxhighlight lang="cpp">
void (*_help)(MessageStatus, CDialog&);
bool (*_validate)(const char*, CDialog&);
</syntaxhighlight></big>
*_help, holds the address of the help logic (function) or NULL if there is no help function is assigned
*_validate, holds the address of the validation logic (function) or NULL if there is no validation function is assgned

int Maxdatalen, bool* Insertmode,

These constructors pass all their arguments to corresponding arguments of CLineEdit constructor and then set '''_help''' and '''_validate''' attributes to the corresponding incoming arguments
===Method===
<big><syntaxhighlight lang="cpp">
int edit();
</syntaxhighlight></big>
If the container() is NULL then this function works exactly like LineEdit::edit().<br />
If the container() is not NULL:
#If _help function exist, it calls the function passing MessageStatus::SetMessage and container()'s reference as arguments.
#Calls LineEdit's edit()
#If validation function exists, and the terminating key of LineEdit's edit() is a navigation key(see below)
#:It will call the validation function on the Field's _data, if the data is valid, it goes to next step, otherwise it will repeat calling LineEdit's edit().
#After validation is done, if _help function exists, it will recall the help function using MessageStatus::ClearMessage and contianer()'s reference as arguments.
#It will return the terminating key
''Navigation keys are Up key, Down key, Tab key or Enter key.''<br />
''MessageStatus is enumerated in '''cuigh.h'''''
