一个读版本信息的API函数的用法（我想好好久都是错的，急死人了，英语文档又看不懂）

[redwood]

在vc控制台下编译：
#include<windows.h>
#include<iostream.h>
void main()
{
char lptstrFilename[MAX_PATH];
DWORD dwHandle;
char dwLen[MAX_PATH];
char *lpData ;
BOOL success;
cout<<"please cin filename"<<endl;
cin>>lptstrFilename;
success=GetFileVersionInfo(lptstrFilename,dwHandle,dwLen,&lpData);
if(success)
cout<<lpData<<endl;
希望各位大哥给改一下

}

char *lpData ;
GetFileVersionInfo(lptstrFilename,dwHandle,dwLen,lpData);


char lpData ;
GetFileVersionInfo(lptstrFilename,dwHandle,dwLen,&lpData);

[windyloft]

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.
);

[windyloft]

lptstrFilename
Pointer to a null-terminated filename string that specifies the file of interest.
Windows 95 and Windows 98: The short path form of the specified file name must be less than 126 characters.

dwHandle
This parameter is ignored.
dwLen
Specifies the size, in bytes, of the buffer pointed to by the lpData member.
Call the GetFileVersionInfoSize function first to determine the size, in bytes, of a file's version information. The dwLen member should be equal to or greater than that value.

If the buffer pointed to by lpData is not large enough, the function truncates the file's version information to the size of the buffer.

lpData
Pointer to a buffer to receive file-version information.
You can use this value in a subsequent call to the VerQueryValue function to retrieve data from the buffer.

The file version information is always in Unicode format.

同意楼上的
char lpData[bufferSize];
GetFileVersionInfo(lptstrFilename,dwHandle,dwLen,&lpData);

大哥些，直接把我的源代码改了吧。我真的看不懂英语啊！！！！谢谢

[bluebohe]

#include "stdafx.h"
#include<windows.h>
#include<iostream.h>
void main()
{
char lptstrFilename[MAX_PATH]="E:\\NOTEPAD.EXE";
DWORD dwLen=0;
char *lpData=NULL ;
unsigned long iHandle;
BOOL success;
dwLen=GetFileVersionInfoSize(lptstrFilename,&iHandle);
lpData=new char[dwLen];
success=GetFileVersionInfo(lptstrFilename,iHandle,dwLen,lpData);
void *buf=NULL;
unsigned int len=0;
success=VerQueryValue(lpData,"\\",&buf,&len);
VS_FIXEDFILEINFO *pp=(VS_FIXEDFILEINFO*)buf;
delete []lpData;
}

在setting中把version.lib 加入input
