Thread: I need help on these few errors!!

CODE IS:

case WM_COMMAND:
switch(LOWORD(wParam))
{
case CM_FILE_ENTRY:
HDC hDC = GetDC(hwnd);

char f_name[] = "Matt";
TextOut(hDC, 10, 10, f_name, strlen(f_name));
break;
case CM_ABOUT_ABOUT:
MessageBox(hwnd, "About:\n Program: StarBook(Windows)\n Company: Starfield\n Authors: David & Matt\n E-mail: [email protected]\n Web site: none yet", "About", MB_OK + MB_ICONINFORMATION);
break;
case CM_FILE_EXIT:
PostQuitMessage(0);
break;
}
break;

ERRORS ARE:

86 book_windows.cpp
jump to case label

83 book_windows.cpp
crosses initialization of `char f_name[5]'

81 book_windows.cpp
crosses initialization of `struct HDC__ * hDC'

89 book_windows.cpp
jump to case label

83 book_windows.cpp
crosses initialization of `char f_name[5]'

81 book_windows.cpp
crosses initialization of `struct HDC__ * hDC'

You'll have to take your declarations out of your case labels -

case WM_COMMAND:
switch(LOWORD(wParam))
{ HDC hDC;
char f_name[80];
case CM_FILE_ENTRY:
hDC= GetDC(hwnd);
f_name[] = "Matt";
TextOut(hDC, 10, 10, f_name, strlen(f_name));
break;
case CM_ABOUT_about :

//etc

actually you can use brackets

case WM_COMMAND:
switch(LOWORD(wParam))
{
case CM_FILE_ENTRY:
{
HDC hDC = GetDC(hwnd);

char f_name[] = "Matt";
TextOut(hDC, 10, 10, f_name, strlen(f_name));
}
break;
case CM_ABOUT_about :
MessageBox(hwnd, "about :\n Program: StarBook(Windows)\n Company: Starfield\n Authors: David & Matt\n E-mail: [email protected]\n Web site: none yet", "About", MB_OK + MB_ICONINFORMATION);
break;
case CM_FILE_EXIT:
PostQuitMessage(0);
break;
}
break;

Also you are not releasing the DC you go with GetDC before the break.

I use a | not a + for the messagebox flags. You don't need the MB_OK as this is the default.

To format the text as centred try

GetTextExtentPoint32(hdc, Title1, lstrlen(sTitle1), &Size);
XStart=(int)(((DisplayRect.right)-Size.cx)/2);//center
TextOut(hdc, XStart,YStart,sTitle1,lstrlen(sTitle1));
YStart+=(int)(Size.cy);
