有没有api函数能知道文件的版本？

有没有api函数能知道文件的版本？
比如*.dwg 我要知道是R14还是R2000
有源代码吗？

[invalid]

用UltraEdit打开两个文件比较一下，应该在文件头部有版本号的。分析得到规律了自己用文件读写函数判断。

[xuv2002]

BOOL GetFileVersionInfo(

LPTSTR lptstrFilename, // pointer to filename string
DWORD dwHandle, // ignored
DWORD dwLen, // size of buffer
LPVOID lpData // pointer to buffer to receive file-version info.
);


The GetFileVersionInfo function returns version information about a specified file.

同意 invalid(空心菜)，自己弄才有乐趣。

代码我给你贴贴
AnsiString file = "d:\\winnt\\hh.exe";
unsigned int m_uiDataSize = GetFileVersionInfoSize(file.c_str(),NULL);
LPVOID m_lpBuffer = malloc(m_uiDataSize); memset(m_lpBuffer,0,m_uiDataSize);
GetFileVersionInfo(file.c_str(),NULL,m_uiDataSize,m_lpBuffer);
LPVOID m_lpData=malloc(80);memset(m_lpData,0,80);
AnsiString productname;
VerQueryValue(m_lpBuffer,
TEXT("\\StringFileInfo\\040904B0\\ProductName"), //产品名称
&m_lpData,
&m_uiDataSize);
productname.sprintf("%s",m_lpData);
AnsiString ProductVersion;
VerQueryValue(m_lpBuffer,
