Title: How to show your application version in a label.
Question: How i can show the version number of my application in a form?
Answer:
First of all, sorry for my bad english, but i don't speak it usually.
There are two methods to show your application version number. One of them is to write it manually in a label. But is a few laborious, because you must rewrite it everytime you release a new version or rebuild your project.
The other one is to write a function than make it for you. To do this, you can use the following functions. Just put there in your code.
// -------------------------------------------------------------------------//
procedure GetBuildInfo(var V1, V2, V3, V4: Word);
var
VerInfoSize, VerValueSize, Dummy : DWORD;
VerInfo : Pointer;
VerValue : PVSFixedFileInfo;
begin
VerInfoSize := GetFileVersionInfoSize(PChar(ParamStr(0)), Dummy);
GetMem(VerInfo, VerInfoSize);
GetFileVersionInfo(PChar(ParamStr(0)), 0, VerInfoSize, VerInfo);
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;
FreeMem(VerInfo, VerInfoSize);
end;
// -------------------------------------------------------------------------//
function kfVersionInfo: String;
var
V1, // Major Version
V2, // Minor Version
V3, // Release
V4: Word; // Build Number
begin
GetBuildInfo(V1, V2, V3, V4);
Result := IntToStr(V1) + '.'
+ IntToStr(V2) + '.'
+ IntToStr(V3) + '.'
+ IntToStr(V4);
end;
// -------------------------------------------------------------------------//
Finally, put a TLabel on your MainForm and write this:
Label1.Caption := 'My Application - Version ' + kfVersionInfo;
That's All!!
You can also show the version number in the MainForm Caption:
MainForm.Caption := 'My Application - Version ' + kfVersionInfo;
I Hope this be usefull for someone.
