How to determine Delphi Application Version - delphi

Question

Want to obtain Delphi Application build number and post into title bar

Answer 1

Here is how I do it. I put this in almost all of my small utilities:
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;

Answer 2

I most strongly recommend not to use GetFileVersion when you want to know the version of the executable that is currently running! I have two pretty good reasons to do this:
The executable may be unaccessible (disconnected drive/share), or changed (.exe renamed to .bak and replaced by a new .exe without the running process being stopped).
The version data you're trying to read has actually already been loaded into memory, and is available to you by loading this resource, which is always better than to perform extra (relatively slow) disk operations.
To load the version resource in Delphi I use code like this:
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;

Thanks to the posts above, I made my own library for this purpose.
I believe that it is a little bit more correct than all other solutions here, so I share it - feel free to reuse it...
unit KkVersion;
interface
function FileDescription: String;
function LegalCopyright: String;
function DateOfRelease: String; // Proprietary
function ProductVersion: String;
function FileVersion: String;
implementation
uses
Winapi.Windows, System.SysUtils, System.Classes, Math;
(*
function GetHeader(out AHdr: TVSFixedFileInfo): Boolean;
var
BFixedFileInfo: PVSFixedFileInfo;
RM: TMemoryStream;
RS: TResourceStream;
BL: Cardinal;
begin
Result := False;
RM := TMemoryStream.Create;
try
RS := TResourceStream.CreateFromID(HInstance, 1, RT_VERSION);
try
RM.CopyFrom(RS, RS.Size);
finally
FreeAndNil(RS);
end;
// Extract header
if not VerQueryValue(RM.Memory, '\\', Pointer(BFixedFileInfo), BL) then
Exit;
// Prepare result
CopyMemory(#AHdr, BFixedFileInfo, Math.Min(sizeof(AHdr), BL));
Result := True;
finally
FreeAndNil(RM);
end;
end;
*)
function GetVersionInfo(AIdent: String): String;
type
TLang = packed record
Lng, Page: WORD;
end;
TLangs = array [0 .. 10000] of TLang;
PLangs = ^TLangs;
var
BLngs: PLangs;
BLngsCnt: Cardinal;
BLangId: String;
RM: TMemoryStream;
RS: TResourceStream;
BP: PChar;
BL: Cardinal;
BId: String;
begin
// Assume error
Result := '';
RM := TMemoryStream.Create;
try
// Load the version resource into memory
RS := TResourceStream.CreateFromID(HInstance, 1, RT_VERSION);
try
RM.CopyFrom(RS, RS.Size);
finally
FreeAndNil(RS);
end;
// Extract the translations list
if not VerQueryValue(RM.Memory, '\\VarFileInfo\\Translation', Pointer(BLngs), BL) then
Exit; // Failed to parse the translations table
BLngsCnt := BL div sizeof(TLang);
if BLngsCnt <= 0 then
Exit; // No translations available
// Use the first translation from the table (in most cases will be OK)
with BLngs[0] do
BLangId := IntToHex(Lng, 4) + IntToHex(Page, 4);
// Extract field by parameter
BId := '\\StringFileInfo\\' + BLangId + '\\' + AIdent;
if not VerQueryValue(RM.Memory, PChar(BId), Pointer(BP), BL) then
Exit; // No such field
// Prepare result
Result := BP;
finally
FreeAndNil(RM);
end;
end;
function FileDescription: String;
begin
Result := GetVersionInfo('FileDescription');
end;
function LegalCopyright: String;
begin
Result := GetVersionInfo('LegalCopyright');
end;
function DateOfRelease: String;
begin
Result := GetVersionInfo('DateOfRelease');
end;
function ProductVersion: String;
begin
Result := GetVersionInfo('ProductVersion');
end;
function FileVersion: String;
begin
Result := GetVersionInfo('FileVersion');
end;
end.

Pass the full file name of your EXE to this function, and it will return a string like:
2.1.5.9, or whatever your version # is.
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;
After defining that, you can use it to set your form's caption like so:
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;

Answer 5

We do this for all our apps but we use a Raize component RzVersioninfo.
works quite well just need to use the following code
on form create
Caption := RzVersioninfo1.filedescripion + ': ' + RzVersionInfo1.FileVersion;
obviously if you don't want any of the other components from raize use one of the options above as there is a cost to the raize components.

Answer 6

From http://www.martinstoeckli.ch/delphi/delphi.html#AppVersion
With this function you can get the version of a file, which contains a
version resource. This way you can display the version number of your
application in an information dialog. To include a version resource to
your Delphi application, set the "Versioninfo" in the project options.

Answer 7

My code:
uses unit Winapi.Windows;
function GetModuleVersion(Instance: THandle; out iMajor, iMinor, iRelease, iBuild: Integer): Boolean;
var
fileInformation: PVSFIXEDFILEINFO;
verlen: Cardinal;
rs: TResourceStream;
m: TMemoryStream;
begin
result := false;
m := TMemoryStream.Create;
try
try
rs := TResourceStream.CreateFromID(Instance, 1, RT_VERSION);
try
m.CopyFrom(rs, rs.Size);
finally
rs.Free;
end;
except
exit;
end;
m.Position:=0;
if not VerQueryValue(m.Memory, '\', Pointer(fileInformation), verlen) then
begin
iMajor := 0;
iMinor := 0;
iRelease := 0;
iBuild := 0;
Exit;
end;
iMajor := fileInformation.dwFileVersionMS shr 16;
iMinor := fileInformation.dwFileVersionMS and $FFFF;
iRelease := fileInformation.dwFileVersionLS shr 16;
iBuild := fileInformation.dwFileVersionLS and $FFFF;
finally
m.Free;
end;
Result := True;
end;
Usage:
if GetModuleVersion(HInstance, iMajor, iMinor, iRelease, iBuild) then
ProgramVersion := inttostr(iMajor)+'.'+inttostr(iMinor)+'.'+inttostr(iRelease)+'.'+inttostr(iBuild);
