Tab characters are displayed as vertical bar (|) characters. The SetWindowText function does not expand tab characters (ASCII code 0x09).

To set the text of a control in another process, send the WM_SETTEXT message directly instead of calling SetWindowText. This is returned by GetWindowText or by sending WMGETTEXT. If the system handles it it will store the text passed to CreateWindow/CreateWindowEx in a dedicated memory area. Either let system handle it or handle it themself. If the control is a list box control created with the WS_CAPTION style, however, SetWindowText sets the text for the control, not for the list box entries. There is two different ways a window can handle its text. If the target window is owned by the current process, SetWindowText causes a WM_SETTEXT message to be sent to the specified window or control. To get extended error information, call GetLastError. However, GetWindowText cannot retrieve the text of a control in another application, If the target window is owned by the current process, GetWindowText causes a WMGETTEXT message to be sent to the specified window or control. If the specified window is a control, the text of the control is copied. If the function fails, the return value is zero. Copies the text of the specified window's title bar (if it has one) into a buffer. If the function succeeds, the return value is nonzero. Syntax BOOL SetWindowTextW(Ī handle to the window or control whose text is to be changed. However, SetWindowText cannot change the text of a control in another application. If the specified window is a control, the text of the control is changed.

I believe the problem occurs with the code to send a message to the text area window (known as hEdit) to grab the text in it & store it in a char array.Changes the text of the specified window's title bar (if it has one). When my program grabs the text from the text area, the text comes out as jobberish or nothing at all? A pointer to a null-terminated string that is the window text. When I click the button, my program grabs the text from the text area & displays the grabbed text in a MessageBox. I have made a simple win32 program that displays a window that has a button & a text area.
