    <p>After spending hours online and coding I found a solution using JNA to get the Version Information for a file.</p> <pre><code>import com.sun.jna.Library; import com.sun.jna.Memory; import com.sun.jna.Native; import com.sun.jna.Pointer; import com.sun.jna.ptr.IntByReference; import com.sun.jna.ptr.PointerByReference; import com.sun.jna.win32.W32APIOptions; import java.io.IOException; public class FileVersionInfo { interface Version extends Library { Version INSTANCE = (Version) Native.loadLibrary("Version", Version.class, W32APIOptions.UNICODE_OPTIONS); public int GetFileVersionInfoSizeW(String lptstrFilename, int dwDummy); public boolean GetFileVersionInfoW(String lptstrFilename, int dwHandle, int dwLen, Pointer lpData); public int VerQueryValueW(Pointer pBlock, String lpSubBlock, PointerByReference lplpBuffer, IntByReference puLen); } static class VS_FIXEDFILEINFO extends com.sun.jna.Structure { public int dwSignature; public int dwStrucVersion; public int dwFileVersionMS; public int dwFileVersionLS; public int dwProductVersionMS; public int dwProductVersionLS; public int dwFileFlagsMask; public int dwFileFlags; public int dwFileOS; public int dwFileType; public int dwFileSubtype; public int dwFileDateMS; public int dwFileDateLS; public VS_FIXEDFILEINFO(com.sun.jna.Pointer p){ super(p); } } public static void main(String[] args) throws IOException { int dwDummy = 0; int versionlength = Version.INSTANCE.GetFileVersionInfoSizeW( "C:\\Test\\chromeinstall.exe", dwDummy); byte[] bufferarray = new byte[versionlength]; Pointer lpData = new Memory(bufferarray.length); PointerByReference lplpBuffer = new PointerByReference(); IntByReference puLen = new IntByReference(); boolean FileInfoResult = Version.INSTANCE.GetFileVersionInfoW( "C:\\Test\\chromeinstall.exe", 0, versionlength, lpData); System.out.println(FileInfoResult); int verQueryVal = Version.INSTANCE.VerQueryValueW(lpData, "\\", lplpBuffer, puLen); VS_FIXEDFILEINFO lplpBufStructure = new VS_FIXEDFILEINFO( lplpBuffer.getValue()); lplpBufStructure.read(); short[] rtnData = new short[4]; rtnData[0] = (short) (lplpBufStructure.dwFileVersionMS &gt;&gt; 16); rtnData[1] = (short) (lplpBufStructure.dwFileVersionMS &amp; 0xffff); rtnData[2] = (short) (lplpBufStructure.dwFileVersionLS &gt;&gt; 16); rtnData[3] = (short) (lplpBufStructure.dwFileVersionLS &amp; 0xffff); for (int i = 0; i &lt; rtnData.length; i++) { System.out.println(rtnData[i]); } } </code></pre>

    1. COThanks for this useful code! Just another side note for people using it: If you use this code inside a class with VS_FIXEDFILEINFO being an inner class, you may get the error "Class com.sun.jna.Structure can not access a member getfield". If so, simply add the keyword `public` to the inner class VS_FIXEDFILEINFO to fix it.

Querying!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
