问题描述

跪求大神帮忙看下代码，错了不晓得怎么改哦

switch (uMsg)
{
case WM_CHAR:
char szChar[20];
sprintf(_T(szChar),_T( "char code is %d"), wParam);

错误 1 error C2065: “LszChar”: 未声明的标识符

IntelliSense: "const wchar_t *" 类型的实参与 "const char *" 类型的形参不兼容

    MessageBox(hwnd, _T(szChar), _T("XX虐编程"), MB_OKCANCEL);
    break;

case WM_LBUTTONDOWN:
    MessageBox(hwnd, TEXT("点了"), TEXT("编程反被XX虐"), MB_OKCANCEL);
    HDC hdc;
    hdc = GetDC(hwnd);
    TextOut(hdc, 50, 50, TEXT("编程反抗了"), strlen(TEXT("编程反抗了")));
    ReleaseDC(hwnd, hdc);
    break;

case WM_PAINT:
    HDC hDc;
    PAINTSTRUCT ps;
    hDc = BeginPaint(hwnd, &ps);
    TextOut(hDc, 50, 50, TEXT("XX还是把它虐了"), strlen(TEXT("XX还是把它虐了")));

错误 3 error C2664: “size_t strlen(const char *)”: 无法将参数 1 从“const wchar_t [6]”转换为“const char *”

错误 4 error C2660: “TextOutW”: 函数不接受 4 个参数

    EndPaint(hwnd, &ps);
    break;

case WM_CLOSE:
    if (IDYES == MessageBox(hwnd, TEXT("编程over啦？"), TEXT("XX虐编程"), MB_YESNO))
        DestroyWindow(hwnd);
    break;

case WM_DESTROY:
    PostQuitMessage(0);
    break;
default:
    return DefWindowProc(hwnd, uMsg, wParam, lParam);
}
错误提示：
错误  1   error C2065: “LszChar”: 未声明的标识符
