do you mind explaining how that works please.

this is what i want to ultimatly acheive: char text[10]=textBox2->Text;

however as you know that would send me an error so i was wondering how it could be done

See http://msdn.microsoft.com/en-us/library/ms235631(VS.80).aspx instead. Shows various conversions, including the one you are looking for.

Note that you (and everyone) should be using Unicode chars. This is the era of globalizaiton. :D Use wchar_t instead.

I use another C language for pic's that require the use of char arrays so i need to be brought up to date this is my code:

 				 DCB dcb = {0}; 
				 DWORD byteswritten;
				 char text[10]=textBox2-Text;
				 LPCVOID pointer = &text;
				 HANDLE hPort = CreateFile(   L"COM4",  
											  GENERIC_READ|GENERIC_WRITE, 
											  0, 
											  NULL, 
											  OPEN_EXISTING, 
											  0, 
											  NULL);

				 if(hPort==INVALID_HANDLE_VALUE)
				 {
					 label8->Text="Invalid Handle";
				 }

				 if (!GetCommState(hPort,&dcb))
				 {
					label8->Text="Error";

				 }
				 
				 dcb.BaudRate = CBR_19200;  //19200 Baud 
				 
				 SetCommState(hPort,&dcb);




				 bool retVal = WriteFile(hPort,pointer,10,&byteswritten,NULL); 
				 CloseHandle(hPort);

please advise on how i can convert the system::string into a wchar_t and still be able to retreive a pointer for the writefile function,

before you ask no this isn't a homework project, just me messing around with the com ports and come to a bit of a halt,

i appreciate your help,

Dave
