在for(）循环中创建复选框

creating checkboxes in for() loop

本文关键字：创建 复选框 循环 for      更新时间：2023-10-16

我想在for（）循环中创建31个复选框。我的代码：

for (int i = 1; i<32; i++)
{
    wchar_t buffer[256];
    std::swprintf(buffer, sizeof(buffer) / sizeof(*buffer), L"1", i);
    g_hPrzycisk = CreateWindowEx(0, "BUTTON", buffer, WS_CHILD | WS_VISIBLE | BS_CHECKBOX, 
        polozenie, 100, 30, 30, hwnd, NULL, hInstance, NULL);
    polozenie = polozenie + 30;
}

错误

C:UsersKomputerDesktopgrafikGrafikOnClickmain.cpp In function 'int WinMain(HINSTANCE, HINSTANCE, LPSTR, int)':
66  120 C:UsersKomputerDesktopgrafikGrafikOnClickmain.cpp [Error] invalid conversion from 'int' to 'LPCSTR {aka const char*}' [-fpermissive]

我做错了什么？？

我看不到错误，但这些是纠正的其他错误

for (int i = 1; i<32; i++)
{
    wchar_t buffer[256];
    std::swprintf(buffer, sizeof(buffer) / sizeof(*buffer), L"%d", i);
    //                                                         ^___ corect this
    CreateWindowEx(0, TEXT("BUTTON"), buffer, WS_CHILD | WS_VISIBLE | BS_CHECKBOX, 
    //                ^^^___ and this (TEXT) macro
    // ^___ you can also drop this 'g_hPrzycisk' (is not an error)
        polozenie, 100, 30, 30, hwnd, NULL, hInstance, NULL);
    polozenie = polozenie + 30;
}
