 Posted: Thu Jan 31, 2008 10:36 am Post subject: New to C++ |
 |
|
I'm new to C++, I borrowed this C++ book from a friend but I know now that just going through the whole book isnt gonna teach me alot coz Ill forget alot anyway, it's better to just make program's and you'll learn from that, but the book doesnt explain how to make a graphics interfaced program, instead of just calculations through the console...
I just need a window and add some buttons to it which WriteProcessMemory.
Any tuts on that?
Thanks in advance.

Learn the basics first. For a basic window your using quite alot.
| Code: |
#include <windows.h>
const char g_szClassName[] = "myWindowClass";
// Step 4: the Window Procedure
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch(msg)
{
case WM_CLOSE:
DestroyWindow(hwnd);
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd, msg, wParam, lParam);
}
return 0;
}
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
WNDCLASSEX wc;
HWND hwnd;
MSG Msg;
//Step 1: Registering the Window Class
wc.cbSize = sizeof(WNDCLASSEX);
wc.style = 0;
wc.lpfnWndProc = WndProc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hInstance = hInstance;
wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wc.lpszMenuName = NULL;
wc.lpszClassName = g_szClassName;
wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
if(!RegisterClassEx(&wc))
{
MessageBox(NULL, "Window Registration Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}
// Step 2: Creating the Window
hwnd = CreateWindowEx(
WS_EX_CLIENTEDGE,
g_szClassName,
"The title of my window",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT, 240, 120,
NULL, NULL, hInstance, NULL);
if(hwnd == NULL)
{
MessageBox(NULL, "Window Creation Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}
ShowWindow(hwnd, nCmdShow);
UpdateWindow(hwnd);
// Step 3: The Message Loop
while(GetMessage(&Msg, NULL, 0, 0) > 0)
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
return Msg.wParam;
}

I got this code from this site's tutorial http://www.winprog.org/tutorial/simple_window.html
And remember learn the standard c++ then move to the windows api.

if your gonna do C++ you learn functional programming.
if you want easy drag and drop gui's then you learn C#.NET
For C++ there is .NET but i dont recomend using that since C# is just right there.
theForger's Win32 API Tutorial:
http://www.winprog.org/tutorial/
Edit: haha, i missed like eveyrones post cuz i got distractd and never hit submit until like 5 minutes later loll

nope, you just dont know how to define text as UNICODE 
see unless you change your project settings to "Use Multi-byte charecter set" you MUST add 1 of the 3 below because you are using UNICODE
1. an L before the string
Example: L"Hi My Name is Lurc"
2. defining it using TEXT
Example: TEXT("Hi My Name is Lurc")
3. Including tchar.h and then using _T (same as TEXT but shorter and neater)
Example: _T("Hi My Name is Lurc")

yes dialogs are there for C++ but im talking EASY.
even using dialogs needs a bit of knowledge about what your doing, with C# its drag and drop, double click for event, etc. its simple and you can learn quickly since eveyrthings basically already given to u.
