C语言实现窗体程序，DevC++ 窗体应用

DevC++ 窗体应用，C语言窗体程序

对于很多学习C语言的同学来说，平时自己写的都是控制台程序，一个黑板版，很难受。
今天教大家用C，写出一个九九乘法表的窗体exe。

效果

创建一个文件，扩展名.c，然后把源码复制上去。
修改时，把自己要绘制的内容放入第三行draw函数里面就可以啦。
好吧，直接上源码：

#include <string.h>
#include <windows.h>
void draw(HWND hwnd) {
    HDC hdc;PAINTSTRUCT ps;RECT rect;hdc = BeginPaint(hwnd, &ps);GetClientRect(hwnd, &rect);//字符串1//SetTextColor(hdc,RGB(255,0,0));DrawText(hdc,TEXT ("卧槽，我在哪儿？"), -1,&rect,DT_TOP|DT_CENTER);//字符串2rect.left=0;rect.top=30;//SetTextColor(hdc,RGB(69,116,224));DrawText(hdc,TEXT ("乘法口诀表："), -1,&rect,DT_TOP);//字符串3char str[2000]="";int i;int j;for (i= 1; i <= 9; ++i) {
    for (j = 1; j <= i; ++j) {
    char a1[10],a2[10],a3[10];itoa(i,a1,10);itoa(j,a2,10);itoa(i*j,a3,10);strcat(str, a1);strcat(str, "x");strcat(str, a2);strcat(str, "=");strcat(str, a3);strcat(str, " ");}strcat(str,  "\n");}rect.left=0;rect.top=60;//SetTextColor(hdc,RGB(87,30,210));DrawText(hdc,TEXT (str), -1,&rect,DT_TOP);EndPaint(hwnd, &ps);
}LRESULT CALLBACK WndProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam) {
    switch (Message) {
    case WM_PAINT:draw(hwnd);break;case WM_DESTROY:PostQuitMessage(0);break;default:return DefWindowProc(hwnd, Message, wParam, lParam);}return 0;
}int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {
    WNDCLASSEX wc;HWND hwnd;MSG msg;memset(&wc, 0, sizeof(wc));wc.cbSize = sizeof(WNDCLASSEX);wc.lpfnWndProc = WndProc;wc.hInstance = hInstance;wc.hCursor = LoadCursor(NULL, IDC_ARROW);wc.hbrBackground = (HBRUSH) (COLOR_WINDOW + 1);wc.lpszClassName = "WindowClass";wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION);if (!RegisterClassEx(&wc)) {
    MessageBox(NULL, "Window Registration Failed!", "Error!", MB_ICONEXCLAMATION | MB_OK);return 0;}hwnd = CreateWindowEx(WS_EX_CLIENTEDGE,"WindowClass","C语言实现窗体",WS_VISIBLE | WS_OVERLAPPEDWINDOW,CW_USEDEFAULT,CW_USEDEFAULT,600,300,NULL, NULL, hInstance, NULL);if (hwnd == NULL) {
    MessageBox(NULL, "Window Creation Failed!", "Error!", MB_ICONEXCLAMATION | MB_OK);return 0;}while (GetMessage(&msg, NULL, 0, 0) > 0) {
    TranslateMessage(&msg);DispatchMessage(&msg);}return msg.wParam;
}

代码你也看完了，求关注不过分吧。
