c++ - char类型的参数* lpcwstr类型的参数

Question

我在c++上收到错误“类型为char的参数*类型为lpcwstr的参数”，该如何修复？

char text[MAX_PATH]= {};
sprintf(text, "Number of Words: %S", computerName);
sprintf(text, "Number of Sentences: %S", userName);
sprintf(text, "Number of Digits: %d", objSystemInfo.dwNumberOfProcessors);
sprintf(text, "Number of Upper Case: %d", bit);
MessageBox(NULL, text , L"Sistem Bilgisi", MB_OK);

Answer 1

MessageBox接收LPCWSTR，您可以将其表示为wchar_t而不是char，并使用wsprintf在wchar_t中进行写入，如下所示:

wchar_t text[MAX_PATH]= {};
wsprintf(text, L"Number of Words: %s", computerName);
wsprintf(text, L"Number of Sentences: %s", userName);
wsprintf(text, L"Number of Digits: %d", objSystemInfo.dwNumberOfProcessors);
wsprintf(text, L"Number of Upper Case: %d", bit);
MessageBox(NULL, text , L"Sistem Bilgisi", MB_OK);
