Hello World

[hgm]

Does anyone happen to know an example of a "Hello World" program in plain C that speaks the sentence using the Windows SAPI?

[JuLieN]

Here it is (Windows in all its concision...) :

Code: Select all

/*

  WINHELLO.C
  ==========
  (c) Paul Griffiths 1999
  Email: mail@paulgriffiths.net

  "Hello, world!", Win32 style.

*/

#include <windows.h>

LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);


/*  WinMain(), our entry point  */

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
		   LPSTR szCmdLine, int iCmdShow) {
    static char szAppName[] = "winhello";
    HWND        hwnd;
    MSG         msg;
    WNDCLASSEX  wndclass;


    /*  Fill in WNDCLASSEX struct members  */

    wndclass.cbSize         = sizeof(wndclass);
    wndclass.style          = CS_HREDRAW | CS_VREDRAW;
    wndclass.lpfnWndProc    = WndProc;
    wndclass.cbClsExtra     = 0;
    wndclass.cbWndExtra     = 0;
    wndclass.hInstance      = hInstance;
    wndclass.hIcon          = LoadIcon(NULL, IDI_APPLICATION);
    wndclass.hIconSm        = LoadIcon(NULL, IDI_APPLICATION);
    wndclass.hCursor        = LoadCursor(NULL, IDC_ARROW);
    wndclass.hbrBackground  = (HBRUSH) GetStockObject(WHITE_BRUSH);
    wndclass.lpszClassName  = szAppName;
    wndclass.lpszMenuName   = NULL;

    
    /*  Register a new window class with Windows  */

    RegisterClassEx(&wndclass);


    /*  Create a window based on our new class  */

    hwnd = CreateWindow(szAppName, "Hello, world!",
			WS_OVERLAPPEDWINDOW,
			CW_USEDEFAULT, CW_USEDEFAULT,
			CW_USEDEFAULT, CW_USEDEFAULT,
			NULL, NULL, hInstance, NULL);


    /*  Show and update our window  */

    ShowWindow(hwnd, iCmdShow);
    UpdateWindow(hwnd);


    /*  Retrieve and process messages until we get WM_QUIT  */

    while ( GetMessage(&msg, NULL, 0, 0) ) {
	TranslateMessage(&msg);    /*  for certain keyboard messages  */
	DispatchMessage(&msg);     /*  send message to WndProc        */
    } 


    /*  Exit with status specified in WM_QUIT message  */

    return msg.wParam;
}


/*  Window procedure  */

LRESULT CALLBACK WndProc(HWND hwnd, UINT iMsg, WPARAM wParam, LPARAM lParam) {
    PAINTSTRUCT ps;
    HDC         hdc;

    
    /*  Switch according to what type of message we have received  */

    switch ( iMsg ) {
    case WM_PAINT:

	/*  We receive WM_PAINT every time window is updated  */

	hdc = BeginPaint(hwnd, &ps);
	TextOut(hdc, 100, 100, "Hello, world!", 13);
	EndPaint(hwnd, &ps);
	return 0;

    case WM_DESTROY:

	/*  Window has been destroyed, so exit cleanly  */

	PostQuitMessage(0);
	return 0;
    }


    /*  Send any messages we don't handle to default window procedure  */
    
    return DefWindowProc(hwnd, iMsg, wParam, lParam);
}

This does not speak, does it? It only prints.

Oh, sorry, I thought that was a figure of speech, when you wrote "speaks"...

But I guess you probably yet saw Microsoft's SAPI tutorial ?
http://msdn.microsoft.com/en-us/library ... s.85).aspx

It's all C++ though...

[hgm]

Indeed, that is the problem. I would need an example how to make it work from a C program. (In particular, WinBoard for the visually impaired...)

That explains where the Winboard users come from! ^^

(Sorry, H.G., I had to make the joke! )

Try the bottom of this article. I have not installed the SAPI SDK so I could not compile it. But it looks plausible. You need to remove the "::" qualifiers, define COBJMACROS, change the calls "pVoice->..." into "ISpVoice_...", and hope for the best

Be sure to fix the syntax error near the end of the line containing "CoCreateInstance". Also watch out for necessary #include-s.

Link fixed.

I am not sure if this is what you mean but Petzold Programming for windows 95 has an example of a speaking program in chapter 1.

Let me know please if you are interested then i go look it up for you.

You can execute C++ code from a c program:
http://dsc.sun.com/solaris/articles/mix ... cpp_from_c

Here there is a SAPI hello world program in C++:
http://msdn.microsoft.com/en-us/library ... 85%29.aspx

Or if as want to do things directly, this thread is about using SAPI 5.3 in c:
http://cboard.cprogramming.com/c-progra ... api-c.html

or you could use a TTS written for c:
http://www.speech.cs.cmu.edu/flite/index.html

Good luck!
