Convert char[] to LPCWSTR

Question

Can anyone help me to correct this code:

    char szBuff[64];
    sprintf(szBuff, \"%p\", m_hWnd);
    MessageBox(NULL, szBuff, L\"Test print handler\", MB_O

Using MultiByteToWideChar() works for me:

void main(int argc, char* argv[])
{
 ...
 wchar_t filename[4096] = {0};
 MultiByteToWideChar(0, 0, argv[1], strlen(argv[1]), filename, strlen(argv[1]));

 // RenderFile() requires LPCWSTR (or wchar_t*, respectively)
 hr = pGraph->RenderFile(filename, NULL);
 ...
}
