c语言编辑框

为了在C语言中创建编辑框，你可以使用Windows API中的CreateWindow函数和Edit类。以下是一个简单示例：

#include <windows.h>

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam);

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
                   LPSTR lpCmdLine, int nCmdShow)
{
    // Register the window class.
    const char CLASS_NAME[]  = "MyClass";
    
    WNDCLASS wc = { };

    wc.lpfnWndProc   = WndProc;
    wc.hInstance     = hInstance;
    wc.lpszClassName = CLASS_NAME;

    RegisterClass(&wc);

    // Create the window.
    HWND hwnd = CreateWindowEx(
        0,                              // Optional window styles.
        CLASS_NAME,                     // Window class
        "C语言编辑框",                  // Window text
        WS_OVERLAPPEDWINDOW,            // Window style

        // Size and position
        CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,

        NULL,       // Parent window    
        NULL,       // Menu
        hInstance,  // Instance handle
        NULL        // Additional application data
        );

    if (hwnd == NULL)
    {
        return 0;
    }

    ShowWindow(hwnd, nCmdShow);

    // Run the message loop.
    MSG msg = { };
    while (GetMessage(&msg, NULL, 0, 0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    return 0;
}

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
    switch (msg)
    {
        case WM_DESTROY:
            PostQuitMessage(0);
            break;

        default:
            // Handle other messages.
            return DefWindowProc(hwnd, msg, wParam, lParam);
    }

    return 0;
}

这将创建一个空白窗口。要在该窗口中添加编辑框，请在WndProc函数中添加以下代码：

case WM_CREATE:
{
    HWND hwndEdit = CreateWindowEx(
        WS_EX_CLIENTEDGE,               // Optional styles
        "EDIT",                         // Edit class
        "",                             // Text
        WS_CHILD | WS_VISIBLE | ES_MULTILINE | ES_AUTOVSCROLL | ES_AUTOHSCROLL,
        0, 0, 100, 100,                 // Position and size
        hwnd,                           // Parent window
        NULL,                           // No menu
        GetModuleHandle(NULL),          // Instance handle
        NULL                            // Pointer to extra data
    );

    if (hwndEdit == NULL)
    {
        MessageBox(hwnd, "Could not create edit box.", "Error", MB_OK | MB_ICONERROR);
    }
}
break;

这将在窗口中创建一个具有多行文本编辑功能的编辑框。你可以在CreateWindowEx函数中通过修改样式和位置来调整编辑框的大小和外观。
