hi,
i am new to c++ (used to program in java and c#)
for several days i have been trying to change gui from a thread,
i searched all the internet but couldnt find anything related,
i am using Borland c++ builder 6,

here is my code
hope
you ll find a solution

Code:
DWORD WINAPI TForm1::m_check(LPVOID param)
{
        DWORD status;
        HANDLE m_con[2];
        m_con[0] = report;
        m_con[1] = hExitEvent;
        while(true)
        {
                status = WaitForMultipleObjects(2,m_con,FALSE,INFINITE);
                Sleep(10); //do not use processor 100%
                switch(status)
                {
                        case WAIT_OBJECT_0:
                        Form1->write(message);
                        break;
                        case WAIT_OBJECT_0 +1:
                        return NULL;//exit

                        case WAIT_FAILED:
                        Form1->write("wait failed");
                        break;
                        default:
                        Form1->write("fail");
                        break;
                }



        }
}
this part is called by a thread when a button is clicked and runs
until exitevent is set
;

Code:
void TForm1::write(AnsiString inp)
{
      Edit1->Text += inp+"\n";
}
and code to modify gui
this all code doesnt gives an error but it doesnt changes anything on gui

when i put a break point on
Edit->Text
as i see text is changed but it doesnt appears at gui
