I would appreciate it if anyone could give me the solution to show different language text in the whiteboard.

I did research and had tried GetwindowTextW with UTF8 unicode, but it still showing "?". SetWindowPos(NULL, 0, 0, size.cx, size.cy, SWP_NOMOVE) void CHBEdit::OnChange()ĬFont *Oldfont = (CFont *)pDC->SelectObject(&m_Font) ĬSize size = pDC->GetOutputTextExtent(str) //+ "a") The following is the code spinet for onchange. However, when I type Japanese text (Non system default language) it shows "?" instead. When the user type in the whiteboard, the onchange function will called and will show the text in the whiteboard. Recall that SendMessage delivers the message directly to the window procedure the message pump never sees it.How to get different language text by GetWindowText? Dweeb I have never worked outside the console with c++ so I am having a hard time bridging my working code and a text box with a button- It shouldn't matter where the string you're trying to process comes from, whether it is a file, from the keyboard, a text box, a socket, hard-coded into the program, etc.

If you use any of the above send-type functions to send a message to a window that belongs to the sending thread, the call is made synchronously. The behavior of sending messages has previously been highlighted on Raymond Chen's excellent blog, The Old New Thing, which all Win32 developers ought to subscribe to: The function dispatches incoming sent messages until a posted message is available for retrieval.ĭispatches incoming sent messages, checks the thread message queue for a posted message, and retrieves the message (if any exist). Retrieves a message from the calling thread's message queue. The SendMessage function calls the window procedure for the specified window and does not return until the window procedure has processed the message. If the message is sent from the same thread, SendMessage will call the window procedure. If you create a new MFC project it will be setup in Unicode and MFC functions will default to Unicode.

You may need UTF16/UTF8 conversion only when exporting/importing data to other systems. UTF8 standard is commonly used with Linux and internet. Sent messages do not go through DispatchMessage, rather GetMessage (or PeekMessage or MsgWaitForMultipleObjects) will call the window procedure directly. Windows uses UTF16 Unicode standard, with wchart wide string. Messages sent to a window are always processed in the thread which created the window (windows have 'thread affinity'). Sent messages do not go through DispatchMessage, rather GetMessage (or PeekMessage or MsgWaitForMultipleObjects) will call the window procedure directly, for messages sent from another thread. GetWindowText is just a thin wrapper for SendMessage (WMGETTEXT). Messages sent to a window are always processed in the thread which created the window (windows have "thread affinity"). GetWindowText is just a thin wrapper for SendMessage(WM_GETTEXT).
