高分求GetFileVersionInfo用法? 分数不够可以再加!

[le123]

GetFileVersionInfo怎么用? 大虾请给出实例!
别忘了,定义变量,结构都写出来,感激不尽!

没用过，顶。

【函数】
GetFileVersionInfo

【操作系统】
Win9x:Y
WinNT:Y

【声明】
Function ulong GetFileVersionInfo(ref string lptstrFilename,ulong dwHandle,ulong dwLen,ref Any lpData) LIBRARY "version.dll" ALIAS FOR "GetFileVersionInfoA"

【说明】

从支持版本标记的一个模块里获取文件版本信息


【返回值】

Long，非零表示成功，零表示失败。会设置GetLastError

【其它】

请看vb的api文本查看器中的声明：Declare Function
GetFileVersionInfo Lib "version.dll" Alias "GetFileVersionInfoA"
(ByVal lptstrFilename As String, ByVal dwHandle As Long, ByVal dwLen As Long, lpData As
Any) As Long

【参数列表】
lptstrFilename - String，欲从中载入版本信息的一个文件的名字

dwHandle ------- Long，win32中未用

dwLen ---------- Long，由lpData参数指定的字节数组或缓冲区的大小。用GetFileVersionInfoSize函数判断要求的缓冲区长度有多大

lpData --------- Byte，指定一个字节缓冲区的第一个字节。该缓冲区用于装载文件的版本信息

您的挺不错,只不过是VB的例子,我要咱PB的例子

[lovelihp]

API的，就是VB例子比较好找。。

[polestarxu]

收藏,PB和VB相差不是太大,呵呵

[le123]

还有没有人会呀?

[青锋-SS]

没用过.

[LearnPro]

这个是刚刚在pb找到的，可以用但是一个不小心编译器会崩溃（是pb官方的例子)
声明:
FUNCTION boolean GetFileVersionInfoA(ref string filename, ulong f_handle, ulong f_length, ref lpdata lpdata2) LIBRARY "version.dll"

结构体:
struct lpdata
ulong dwsignature
ulong dwstrucversion
ulong dwfileversionms
ulong dwfileversionls
ulong dwproductversionms
ulong dwproductversionls
ulong dwfileflagsmask
ulong dwfileflags
ulong dwfileos
ulong dwfiletype
ulong dwfilesubtype
ulong dwfiledatems
ulong dwfiledatels
}
代码例子
boolean lb_rtn
string ls_filename
ulong lu_hand, lu_len
lpdata lpdata2
ls_filename = "c:\windows\calc.exe" // The calculator would be a
good file to test against.
setnull(lu_hand)
lu_len = 256
lb_rtn = GetFileVersionInfoA(ls_filename, lu_hand, lu_len, lpdata2)
// Viewing the output
// -------------------------------------------------------------
sle_1.text = string(lpdata2.dwSignature)
sle_2.text = string(lpdata2.dwStrucVersion)
sle_3.text = string(lpdata2.dwFileVersionMS)
sle_4.text = string(lpdata2.dwFileVersionLS)
sle_5.text = string(lpdata2.dwProductVersionMS)
sle_6.text = string(lpdata2.dwProductVersionLS)
sle_7.text = string(lpdata2.dwFileFlagsMask)
sle_8.text = string(lpdata2.dwFileFlags)
sle_9.text = string(lpdata2.dwFileOS)
sle_10.text = string(lpdata2.dwFileType)
sle_11.text = string(lpdata2.dwFileSubtype)
sle_12.text = string(lpdata2.dwFileDateMS)
sle_13.text = string(lpdata2.dwFileDateLS)
Messagebox("Return Code", string(lb_rtn))
//

这样函数就可以调用了但他容易使pb编译器崩溃。（正在找这个原因）

[LearnPro]

lu_len = 256
可以用函数 GetFileVersionInfoSize代替(256太小)
