| And the *actual* problem is ...? Your subject is not descriptive at all,
| and you only posted code but not a single word as to explain what is wrong
| with it. If you do not provide details, nobody can help you.
|
| I suspect you are trying to refer to the following line of code:
|
| AnsiString Number = TDBEdit(Compon)->Text;
|
| That is not a correct way to cast a pointer in C++. That looks like you
are
| trying to adapt Delphi code to C++. The correct code should look like
this
| instead:
|
| AnsiString Number = static_cast<TDBEdit*>(Compon)->Text;
|
| That is assuming, of course, that FindComponent() actually found a TDBEdit
| in the first place, otherwise the code will have undefined behavior. If
you
| are not 100% certain that FindComponent() will actually return a TDBEdit,
| then use dynamic_cast instead:
|
| TDBEdit *dbe = dynamic_cast<TDBEdit*>(Compon);
| if( dbe )
| {
| //...
| }
