Another problem with casting into char*

Another problem with casting into char*

Another problem with casting into char*

(OP)
Hello!
I'd like to cast
TString into char *

When I try to use the "c_str()", I do like this:
(Form1->Memo1->Lines).c_str()

But it answears :
'c_str()' is not a member of 'Classes::TStrings'

Is there a specific function for TStrings??
Please help me!

RE: Another problem with casting into char*

c.str() should be the correct method. I use this alot to go from standard C/C++ strings to AnsiStrings and back again. The following snippets work:

string ImpLine;                // import line
.
.
.
// ImpLine is filled from a text file
.
.
.
Memo->Lines->Add(AnsiString(ImpLine.c_str()));
// Memo is expecting it strings to be AnsiString so I change ImpLine to
// a standard C\C++ string with c_str() then cast to AnsiString
.
.
.
// We can do the opposite, too
ImpLine = Edit->Text.c_str();


I think the problem may really be with how you are getting the lines out of Memo1 not really with c_str(). Repost a small piece of code here. You might want to put the code in code blocks to prevent TGML from interpreting the lines. So the Process TGML link below for more help.
