GetWindowText() writes to an array of chars through a character, how to solve?

Question

C++ / C#

the code:

char msg[256];
 GetWindowText(obj.hEDIT,(LPWSTR)&msg, sizeof(msg));
 //SendMessage(obj.hEDIT, EM_GETLINE, 0,(LPARAM)(LPSTR)msg);
 servermessage(msg);
 SendMessage(obj.hListBox, LB_ADDSTRING, 0, (LPARAM)(LPCSTR)msg);

servermessage():

int s = sizeof(msg);
send(hconnect, msg, s, NULL);
return 0;

this is how visual studio debugging sees the msg array:

Answer 1

GetWindowText() writes to an array of chars via character

GetWindowText(obj.hEDIT,(LPWSTR)&msg, sizeof(msg));

If it is a char array, then GetWindowTextA must be used and the pointer to the array must not be cast to the LPWSTR type.
The last argument to GetWindowText, by the way, is not the size of the buffer, but the number of characters in it, so you should (should) have passed not sizeof(msg)a sizeof(msg)/sizeof(*LPWSTR).

Answer 2

Read MSDN. Everything is clearly written what and how. First study - then stupid questions. And not vice versa.
