Hi,
Sorry for my English, i'm French and i don't speak very well this language.
I have a problem, i want to print something into a LineEdit into a thread.
This is what I wrote:
void Processus( bool *boucle, LineEdit *l )
{
while( boucle )
{
l->Insert(-1, "test\n" );
boucle = false;
}
}
...
void Test::ConnexionClient()
{
...
Thread::Start( callback2( Processus, &boucle, &client.lignesClient ) );
boucle = true;
...
}
In lay file i have:
ITEM(LineEdit, lignesClient, LeftPosZ(7, 601).TopPosZ(85, 253))
I have this error when i execute my program:
Can you help me ? How to use GuiLock ?
I'm using TheEDI Windows edition.
Thank you !

Hi !
OK it's work.
I have just a little problem, i want into my thread write into the LineEdit the data received in a socket connexion.
If i have in .h file:
static TcpSocket connexion;
and
void Processus( bool *boucle, LineEdit *l )
{
while( boucle )
{
char ServerResponse[10];
ConnexionTCP::connexion.Get(ServerResponse, 10);
GuiLock __;
...
}
}
I have undefined error in linking in other method of my class:
void ConnexionTCP::fermerConnexion( void )
{
if( connexion.IsOpen() )
connexion.Close();
}
If i remove "static", i have no error but i can't acces to connexion into my thread.
I thing it's probably a C++ syntax error but can you help me ?
Thank you !!!

Hi,
Sorry i'm stupid, i forgot to declare:
TcpSocket ConnexionTCP::connexion;
into cpp file.
Now it's OK.
Thank you for your help, Ultimate C++ is very good !
