- Q: How can I get the Windows or DOS version numbers?
-
- A: The API call GetVersion will do it, but the information is
- encrypted into a longint. Here is how to get and decrypt the information:
- }
-
- Type
- TGetVer = record
- WinVer,
- WinRev,
- DosRev,
- DosVer: Byte;
- end;
-
- const
- VerStr = '%d.%d';
-
- procedure TForm1.Button1Click(Sender: TObject);
- var
- AllVersions: TGetVer;
- begin
- AllVersions := TGetVer(GetVersion);
- Edit1.Text := Format(VerStr, [AllVersions.WinVer, AllVersions.WinRev]);
- Edit2.Text := Format(VerStr, [AllVersions.DOSVer, AllVersions.DOSRev]);
- end;
-
- Note1: The values that windows displays for the versions and the values
- that it returns through its API call are not always the same. e.g. The
- workgroup version displays as 3.10 rather than 3.11.
-
- Note2: Win32 applications should call GetVersionEx rather than GetVersion.
