在使用Inno Setup创建的安装过程中,我需要获取驱动器号的卷序列号.我知道DLL函数可以导入Inno,但我对它很新,并且在使它工作时遇到一些问题.我知道kernel32中的GetVolumeInformation函数可以做我需要的.有人可以告诉我如何在Inno脚本中导入和使用该功能来检索卷序列号吗？
谢谢！
解决方法
Inno-Setup代码::
@H_502_8@[Code]
function GetVolumeInformation(
lpRootPathName: PChar;
lpVolumeNameBuffer: PChar;
nVolumeNameSize: DWORD;
var lpVolumeSerialNumber: DWORD;
var lpMaximumComponentLength: DWORD;
var lpFileSystemFlags: DWORD;
lpFileSystemNameBuffer: PChar;
nFileSystemNameSize: DWORD
): BOOL;
external 'GetVolumeInformationA@kernel32.dll stdcall';
function LoWord(dw: DWORD): WORD;
begin
Result := WORD(dw);
end;
function HiWord(dw: DWORD): WORD;
begin
Result := WORD((dw shr 16) and $FFFF);
end;
function WordToHex(w: WORD): string;
begin
Result := Format('%.4x',[w]);
end;
function FindVolumeSerial(const Drive: string): string;
var
FileSystemFlags: DWORD;
VolumeSerialNumber: DWORD;
MaximumComponentLength: DWORD;
begin
Result := '';
// Note on passing PChars using RemObjects Pascal Script:
// '' pass a nil PChar
// #0 pass an empty PChar
if GetVolumeInformation(
PChar(Drive),'',// nil
0,VolumeSerialNumber,MaximumComponentLength,FileSystemFlags,// nil
0)
then
Result := WordToHex(HiWord(VolumeSerialNumber)) + '-' + WordToHex(LoWord(VolumeSerialNumber));
end;
function InitializeSetup(): Boolean;
begin
MsgBox(FindVolumeSerial('c:\'),mbInformation,mb_Ok);
end;
使用Inno-setup版本5.2.3进行测试在Inno-Setup的Unicode版本中,用PAnsiChar替换PChar
