Adding colour & bmps to a Win 32 Window??
Hi. I am a real newbie with C, and am making a game with my friends as part of a school project. We though it would be a good idea if we made a character guide that gives a description of all of the characters, and a brief run-down of the game. I found a demo window program on DEV C++ (works with C as well) and here is the code:
Code:
/*
* A basic example of Win32 programmiwng in C.
*
* This source code is in the PUBLIC DOMAIN and has NO WARRANTY.

* Colin Peters <[email protected]>
*/
#include <windows.h>
#include <string.h>
#include <iostream>
/*
* This is the window function for the main window. Whenever a message is
* dispatched using DispatchMessage (or sent with SendMessage) this function
* gets called with the contents of the message.
*/
LRESULT CALLBACK
MainWndProc (HWND hwnd, UINT nMsg, WPARAM wParam, LPARAM lParam)
{
/* The window handle for the "Click Me" button. */
static HWND hwndButton = 0;
static int cx, cy;/* Height and width of our button. */
HDC hdc;/* A device context used for drawing */
PAINTSTRUCT ps;/* Also used during window drawing */
RECT rc;/* A rectangle used during drawing */
/*
* Perform processing based on what kind of message we got.
*/
switch (nMsg)
{
case WM_CREATE:
{
/* The window is being created. Create our button
* window now. */
TEXTMETRIC tm;
/* First we use the system fixed font size to choose
* a nice button size. */
hdc = GetDC (hwnd);
SelectObject (hdc, GetStockObject (SYSTEM_FIXED_FONT));
GetTextMetrics (hdc, &tm);
cx = tm.tmAveCharWidth * 30;
cy = (tm.tmHeight + tm.tmExternalLeading) * 2;
ReleaseDC (hwnd, hdc);
/* Now create the button */
hwndButton = CreateWindow (
"button",/* Builtin button class */
"Close",
WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON,
0, 0, cx, cy,
hwnd,/* Parent is this window. */
(HMENU) 1,/* Control ID: 1 */
((LPCREATESTRUCT) lParam)->hInstance,
NULL
);
return 0;
break;
}
case WM_DESTROY:
/* The window is being destroyed, close the application
* (the child button gets destroyed automatically). */
PostQuitMessage (0);
return 0;
break;
case WM_PAINT:
/* The window needs to be painted (redrawn). */
hdc = BeginPaint (hwnd, &ps);
GetClientRect (hwnd, &rc);
/* Draw "Hello, World" in the middle of the upper
* half of the window. */
rc.bottom = rc.bottom / 2;
DrawText (hdc, "Little Fighter Elite Character Guide- By Carey Sizer", -1, &rc,
DT_SINGLELINE | DT_CENTER | DT_VCENTER);
EndPaint (hwnd, &ps);
return 0;
break;
case WM_SIZE:
/* The window size is changing. If the button exists
* then place it in the center of the bottom half of
* the window. */
if (hwndButton &&
(wParam == SIZEFULLSCREEN ||
wParam == SIZENORMAL)
)
{
rc.left = (LOWORD(lParam) - cx) / 2;
rc.top = HIWORD(lParam) * 3 / 4 - cy / 2;
MoveWindow (
hwndButton,
rc.left, rc.top, cx, cy, TRUE);
}
break;
case WM_COMMAND:
/* Check the control ID, notification code and
* control handle to see if this is a button click
* message from our child button. */
if (LOWORD(wParam) == 1 &&
HIWORD(wParam) == BN_CLICKED &&
(HWND) lParam == hwndButton)
{
/* Our button was clicked. Close the window. */
DestroyWindow (hwnd);
}
return 0;
break;
}
/* If we don't handle a message completely we hand it to the system

* are required for idle processing or handling modeless dialog
* boxes. When one of the windows calls PostQuitMessage GetMessage
* will return zero and the wParam of the message will be filled
* with the argument to PostQuitMessage. The loop will end and
* the application will close.

What I want to do is: Add about 15 buttons in the main window that have the characters names on them, and when you click them it opens a mini window- like 150px by 250. These also need a little bmp of the character in them, and a bold title with a blurb about them. It would be handy if they had a scroll bar as well.
We want the colour scheme to a dark blue, and all of the text white. (the buttons as well). I also need to insert a bitmap as a title in the main window.
If you can help me out with doing this, we will put your name + website (or whatever u want- email?) in the credits for the game, and you can add your name in the bottom of the character guide.
Any help is much appreciated!
