Version Number of my application

[Chubbly Geezer]

Hi

I want to check that users have the latest version of an app by checking
it's version number against that held on the server. Would anyone know how
to access this via code.

Thanks

FileVersionInfo.GetVersionInfo(applicationPath)

FileVersionInfo.GetVersionInfo(applicationPath)

.... this will only work locally, IIRC.

Application.ProductVersion is what you are looking for?

OK thanks. that's almost what I need.

However, if I check the values returned from 2 different files (both exactly
the same but in 2 locations) they are always different because the file
location is also returned. What I really need is to just pull back the
version number and not all the other info.

Thanks

Yes it is thanks. Can I direct that to a file held on a server to compare
versions?

You can call GetFileVersionInfo() Win32 API to get the version of the server
exe (using share path such as \\server\share\myexe.exe) and compare it with
the local one.

A sample of GetFileVersionInfo() can be found here (in C# though):

Take a look at the members of 'FileVersionInfo' ('FileBuildPart',
'FileMinorPart', 'FileMajorPart', 'FileVersion', 'ProductBuildPart',
'ProductMinorPart', 'ProductMajorPart').

Look for the FileVersionInfo class in Help

Try

Dim myFileVersionInfo As FileVersionInfo =
FileVersionInfo.GetVersionInfo("E:\Subscriptions\NEW - Subs Reporting
Install\SubsReporting.exe")

If myFileVersionInfo.ProductVersion <> Application.ProductVersion Then

If MessageBox.Show("This product has been updated and you are running an
older version." & vbCrLf & vbCrLf & "Do you wish to get the latest
updates.?", "SUBS REPORTING : WARNING !", MessageBoxButtons.YesNo,
MessageBoxIcon.Question) = DialogResult.Yes Then

Call Shell("C:\Program Files\WARC\Subs Reporting\SubsReportingUpdater.exe",
AppWinStyle.NormalNoFocus)

Application.Exit()

Else

Application.Exit()

End If

End If

myFileVersionInfo = Nothing

Catch objE As Exception

MessageBox.Show(obje.Message, "Error encountered ==> frmMenu_Load")

End Try
