想获得Delphi Application内部版本号并发布到标题栏
答案 0 :(得分:26)
我是这样做的。我把它放在几乎所有的小工具中:
procedure GetBuildInfo(var V1, V2, V3, V4: word);
var
VerInfoSize, VerValueSize, Dummy: DWORD;
VerInfo: Pointer;
VerValue: PVSFixedFileInfo;
begin
VerInfoSize := GetFileVersionInfoSize(PChar(ParamStr(0)), Dummy);
if VerInfoSize > 0 then
begin
GetMem(VerInfo, VerInfoSize);
try
if GetFileVersionInfo(PChar(ParamStr(0)), 0, VerInfoSize, VerInfo) then
begin
VerQueryValue(VerInfo, '\', Pointer(VerValue), VerValueSize);
with VerValue^ do
begin
V1 := dwFileVersionMS shr 16;
V2 := dwFileVersionMS and $FFFF;
V3 := dwFileVersionLS shr 16;
V4 := dwFileVersionLS and $FFFF;
end;
end;
finally
FreeMem(VerInfo, VerInfoSize);
end;
end;
end;
function GetBuildInfoAsString: string;
var
V1, V2, V3, V4: word;
begin
GetBuildInfo(V1, V2, V3, V4);
Result := IntToStr(V1) + '.' + IntToStr(V2) + '.' +
IntToStr(V3) + '.' + IntToStr(V4);
end;
procedure TForm1.FormCreate(Sender: TObject);
begin
Form1.Caption := Form1.Caption + ' - v' + GetBuildInfoAsString;
end;

当您想知道当前正在运行的可执行文件的版本时,我强烈建议您不要使用GetFileVersion!我有两个很好的理由这样做:
要在Delphi中加载版本资源,我使用如下代码:
uses Windows,Classes,SysUtils;
var
verblock:PVSFIXEDFILEINFO;
versionMS,versionLS:cardinal;
verlen:cardinal;
rs:TResourceStream;
m:TMemoryStream;
p:pointer;
s:cardinal;
begin
m:=TMemoryStream.Create;
try
rs:=TResourceStream.CreateFromID(HInstance,1,RT_VERSION);
try
m.CopyFrom(rs,rs.Size);
finally
rs.Free;
end;
m.Position:=0;
if VerQueryValue(m.Memory,'\',pointer(verblock),verlen) then
begin
VersionMS:=verblock.dwFileVersionMS;
VersionLS:=verblock.dwFileVersionLS;
AppVersionString:=Application.Title+' '+
IntToStr(versionMS shr 16)+'.'+
IntToStr(versionMS and $FFFF)+'.'+
IntToStr(VersionLS shr 16)+'.'+
IntToStr(VersionLS and $FFFF);
end;
if VerQueryValue(m.Memory,PChar('\\StringFileInfo\\'+
IntToHex(GetThreadLocale,4)+IntToHex(GetACP,4)+'\\FileDescription'),p,s) or
VerQueryValue(m.Memory,'\\StringFileInfo\\040904E4\\FileDescription',p,s) then //en-us
AppVersionString:=PChar(p)+' '+AppVersionString;
finally
m.Free;
end;
end;

将EXE的完整文件名传递给此函数,它将返回如下字符串: 2.1.5.9,或者你的版本是什么。
function GetFileVersion(exeName : string): string;
const
c_StringInfo = 'StringFileInfo\040904E4\FileVersion';
var
n, Len : cardinal;
Buf, Value : PChar;
begin
Result := '';
n := GetFileVersionInfoSize(PChar(exeName),n);
if n > 0 then begin
Buf := AllocMem(n);
try
GetFileVersionInfo(PChar(exeName),0,n,Buf);
if VerQueryValue(Buf,PChar(c_StringInfo),Pointer(Value),Len) then begin
Result := Trim(Value);
end;
finally
FreeMem(Buf,n);
end;
end;
end;
在定义之后,您可以使用它来设置表单的标题,如下所示:
procedure TForm1.FormShow(Sender: TObject);
begin
//ParamStr(0) is the full path and file name of the current application
Form1.Caption := Form1.Caption + ' version ' + GetFileVersion(ParamStr(0));
end;

来自http://www.martinstoeckli.ch/delphi/delphi.html#AppVersion
使用此功能,您可以获取包含a的文件版本 版本资源。这样您就可以显示您的版本号 应用于信息对话框中。要包含版本资源 您的Delphi应用程序,在项目选项中设置“Versioninfo”。
答案 5 :(得分:0)
我们为所有应用程序执行此操作,但我们使用Raize组件RzVersioninfo。 工作得很好只需要使用以下代码
表单上的
标题:= RzVersioninfo1.filedescripion +':'+ RzVersionInfo1.FileVersion;
显然,如果您不希望raize中的任何其他组件使用上述选项之一,因为raize组件会产生成本。
