Re: Warning?

Hello,

I am trying one of my very first windows program and I am getting the
following warning:

c:\DATASOURCE_EXTRA\Programming\VC++CodeTesting_WINDOWS\TESTING_CPZ\HangTheMan_ProgTest1\HTM.C(51)
: warning C4244: 'return' : conversion from 'WPARAM' to 'int', possible
loss
of data

Here is my code:

#include <windows.h>
#include "HTM.h"

LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM);
const int NUMLINES = (sizeof Words) / (sizeof Words[0]);

//My functions
void DrawOptions(HDC,HWND,BOOL,BOOL,int);

int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInnstance,
PSTR szCmdLine, int iCmdShow)
{
static TCHAR szAppName[] = TEXT ("HTM");
HWND hwnd;
MSG msg;
WNDCLASS 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.hCursor = LoadCursor (NULL, IDC_ARROW);
wndclass.hbrBackground = (HBRUSH) GetStockObject(WHITE_BRUSH);
wndclass.lpszMenuName = NULL;
wndclass.lpszClassName = szAppName;

if (!RegisterClass (&wndclass))
{
MessageBox (NULL, TEXT ("xxx"),szAppName, MB_ICONERROR);
return 0;
}

hwnd = CreateWindow (szAppName, TEXT ("HTM ! "),

WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT,
CW_USEDEFAULT, CW_USEDEFAULT,
NULL, NULL, hInstance, NULL);

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

while (GetMessage (&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return msg.wParam;
}

LRESULT CALLBACK WndProc (HWND hwnd, UINT message,
                                              WPARAM wParam, LPARAM
lParam)

static int ColorTYPE = 1;

switch (message)
{
case WM_CREATE:
 hdc = GetDC (hwnd);

GetTextMetrics (hdc, &tm);
cxChar = tm.tmAveCharWidth;
cxCaps = (tm.tmPitchAndFamily & 1 ? 3 : 2) * cxChar / 2;
cyChar = tm.tmHeight + tm.tmExternalLeading;

ReleaseDC (hwnd, hdc);

return 0;

 case WM_SIZE:

cyClient = HIWORD(lParam);
        return 0;

case WM_PAINT:
               hdc = BeginPaint (hwnd, &ps);

              //MESSAGE BOARD COLORS

for (i = 0; i < NUMLINES; i++)
{
TextOut (hdc,0,cyChar * i,Words[i].szWord,
     lstrlen(Words[i].szWord));

TextOut (hdc,20 * cxChar,cyChar * i,szBuffer,
wsprintf(szBuffer,TEXT("%2d"),Words[i].iWLenght));

}
EndPaint (hwnd, &ps);
return 0;

case WM_DESTROY:

return 0;
}

return DefWindowProc (hwnd, message, wParam, lParam);
}

void DrawOptions(HDC hdc,HWND hwnd,BOOL b_OPAQUE,
                        BOOL b_GRAYBRUSH,int i_ColorTYPE)
{
//Windows objects
HBRUSH hBrush;

//CHOICE OF OPAQUE OR TRANSPARENT
if (b_OPAQUE == TRUE)
{SetBkMode(hdc,OPAQUE);
 SetBkColor(hdc,0);}
else
  {SetBkMode(hdc,TRANSPARENT);
  SetBkColor(hdc,22000);}

  //CHOICE OF COLOR TYPE
  if (i_ColorTYPE == 1)
    {SetTextColor(hdc,65535);}
  else if (i_ColorTYPE == 2)

//SELECT BRUSH COLOR
if (b_GRAYBRUSH == TRUE)
{hBrush = (HBRUSH) GetStockObject(GRAY_BRUSH);}
else
{hBrush = (HBRUSH) GetStockObject(WHITE_BRUSH);}

//SELECT THE BRUSH INTO THE DEVICE CONTEXT
SelectObject(hdc,hBrush);

//DISPLAY RECTANGLE
Rectangle(hdc,0,0,300,300);
}

I have seen this warning before, but now I don't know how to get rid of
it !

Please help, anyone,
