被玩坏的C程序控制台窗口

嗯？听说你在Windows系统上C语言程序？那你对控制台窗口了解多少?

Linux、Mac 的Shell以后有时间再玩….

听说你会写Helloworld程序，我猜一定是这个样子的：

#include<stdio.h>
int main() {return 0&printf("Hello, world!\n");
}

那么问题来了，你会不会写下面这种风格的？

#include<Windows.h>
int main() {HWND hWnd = GetConsoleWindow();HDC hdc = GetDC(hWnd);HFONT font = CreateFont(64, // nHeight0, // nWidth-50, // nEscapement20, // nOrientationFW_BOLD, // nWeightTRUE, // bItalicTRUE, // bUnderline0, // cStrikeOutANSI_CHARSET, // nCharSetOUT_DEFAULT_PRECIS, // nOutPrecisionCLIP_DEFAULT_PRECIS, // nClipPrecisionDEFAULT_QUALITY, // nQualityDEFAULT_PITCH | FF_SWISS,L"Arial" // nPitchAndFamily Arial);SelectObject(hdc, font);SetBkColor(hdc, 0x000000);SetTextColor(hdc, RGB(100,149,237));TextOut(hdc, 30, 30, L"Hello, world!", 13);ValidateRect(hWnd, 0);return 0;
}

绘制文字算什么，还能在控制台窗口上添加按钮 ↓ ↓ ↓，没错就是每天都会点的那种按钮，点了还会有反应！

#include<Windows.h>
#include<iostream>
int main() {HWND hWnd = GetConsoleWindow();HFONT font = CreateFont(20, // nHeight0, // nWidth0, // nEscapement0, // nOrientationFW_NORMAL, // nWeightFALSE, // bItalicFALSE, // bUnderline0, // cStrikeOutANSI_CHARSET, // nCharSetOUT_DEFAULT_PRECIS, // nOutPrecisionCLIP_DEFAULT_PRECIS, // nClipPrecisionDEFAULT_QUALITY, // nQualityDEFAULT_PITCH | FF_SWISS,L"新宋体" // nPitchAndFamily Arial);HWND b1 = CreateWindow(L"BUTTON",   // predefined classL"确定",       // button textWS_VISIBLE | WS_CHILD,  //values for buttons.100,         // starting x position100,         // starting y position100,        // button width40,        // button heighthWnd,       // parent window0,       // No menu(HINSTANCE)GetWindowLong(hWnd, GWL_HINSTANCE),NULL);HWND b2 = CreateWindow(L"BUTTON",   // predefined classL"取消",       // button textWS_VISIBLE | WS_CHILD,  //values for buttons.240,         // starting x position100,         // starting y position100,        // button width40,        // button heighthWnd,       // parent window0,       // No menu(HINSTANCE)GetWindowLong(hWnd, GWL_HINSTANCE),NULL);SendMessage(b1, WM_SETFONT, (WPARAM)font, 1);SendMessage(b2, WM_SETFONT, (WPARAM)font, 1);MSG msg;while (GetMessage(&msg, 0, 0, 0)) {TranslateMessage(&msg);DispatchMessage(&msg);if (msg.hwnd==b1 && msg.message== WM_LBUTTONDOWN) {MessageBox(hWnd, L"点击了确定按钮", L"Hello", MB_ICONINFORMATION);}if (msg.hwnd == b2 && msg.message == WM_LBUTTONDOWN) {MessageBox(hWnd, L"点击了取消按钮", L"Hello", MB_ICONINFORMATION);}}
}

还有更多玩法，既然可以绘制不同字体的文字，当然也可以绘制图片

了解音频视频编码的同学把控制台窗口改造成视频播放器也是可以的！

#include<Windows.h>
#include<stdio.h>
#include<gdiplus.h>
#pragma comment(lib,"gdiplus.lib")
using namespace Gdiplus;int main() {Gdiplus::GdiplusStartupInput m_gdiplusStartupInput;ULONG_PTR m_gdiplusToken;GdiplusStartup(&m_gdiplusToken, &m_gdiplusStartupInput, NULL);HWND hWnd = GetConsoleWindow();HDC hdc = GetDC(hWnd);Image* pImage = Image::FromFile(L"Flandre.jpg");if (!pImage) {printf("无法打开图片 Flandre.jpg");return -1;}Graphics graphics(hdc);graphics.DrawImage(pImage, 0, 0, pImage->GetWidth()/2.5, pImage->GetHeight()/2.5);return 0;
}

接下来是一个圆周运动停不下来的控制台窗口（Enter键终止）

#include<Windows.h>
#include<math.h>
#include<stdio.h>#define PI 3.14159265
#define POSCOUNT 10int position[POSCOUNT][2];DWORD WINAPI task(VOID* hWnd) {RECT rc;GetWindowRect((HWND)hWnd, &rc);int i = 0;while (true){MoveWindow((HWND)hWnd, position[i][0],position[i][1],rc.right - rc.left,rc.bottom - rc.top,TRUE);ShowWindow((HWND)hWnd, SW_SHOW);printf("当前窗口位置： %d,   %d\n", position[i][0], position[i][0]);i++;if (i >= POSCOUNT)i = 0;Sleep(20);}
}int main() {HWND hWnd = GetConsoleWindow();int i = 0;for (;i < POSCOUNT;i++) {position[i][0] = 100 * sin(PI * 2 * i / POSCOUNT) + 300;position[i][1] = 100 * cos(PI * 2 * i / POSCOUNT) + 300;}CreateThread(0, 0, task, hWnd, 0, 0);getc(stdin);
}

最后呢，在控制台窗口上来一发3D渲染好了
