带有 TCHAR 和字符串连接的 C++ 消息框

Question

有人可以告诉我如何在消息框中输出 szFileName 吗？

我下面的尝试不起作用

//Retrieve the path to the data.dat in the same dir as our app.dll is located

TCHAR szFileName[MAX_PATH+1];
GetModuleFileName(_Module.m_hInst, szFileName, MAX_PATH+1);
StrCpy(PathFindFileName(szFileName), _T("data.dat"));

FILE *file =fopen(szFileName,"rb");
if (file)
{
    fseek( file,iFirstByteToReadPos, SEEK_SET);
    fread(bytes,sizeof(unsigned char), iLenCompressedBytes, file);
    fclose(file);
}
else
{
    MessageBox(NULL, szFileName + " not found", NULL, MB_OK);
    DebugBreak();
}

Answer 1

您不能添加:

szFileName + " not found", 

简单修复:

MessageBox(NULL, szFileName, L"File not found", MB_OK);
