[SOLVED] Knowing if a vault is online

How are you connecting to the vault?  Could you test the vault connection?
M-Files API - VaultConnection Object

I get all configured vaults with

Dim client As MFilesClientApplication = New MFilesClientApplication()

For Each vc As VaultConnection In client.GetVaultConnections()
    If (vc.ServerVaultGUID = guidVault) Then
        
        [...]

        Dim t1 = vc.IsLoggedIn()
        Dim t2 = vc.TestConnectionToVault(IntPtr.Zero)
        Exit For
    End If
Next

For the concerned vault, when is offline:

• vc.IsLoggedIn() = true
• myVault.TestConnectionToVault(IntPtr.Zero) = MFilesAPI.MFVaultConnectionTestResult.MFVaultConnectionTestResultOK

EDIT 10h00 :

I'm not deconnected from the network, and I can ping server.

I just want show a message if a user has this vault offline.

I tested this, and it is awkward if the server is online but the vault offline.

Can you wrap your call to BindToVault in a try/catch, and throw a suitable message to the user if it fails?

.BindToVault() don't throw exception.

Exception is throwed only when I want to get all temporary view

vault.ViewOperations.GetViews(MFViewCategory.MFViewCategoryTemporarySearch)

--> System.Runtime.InteropServices.COMException: 'This operation is not allowed in offline mode*.

CoVaultViewOperations.cpp, 158, This operation is not allowed in offline mode*. (0x800407E0)

Ahh, that's a different thing.  Let me have a look.

In that case I think you can use Vault.ClientOperations.IsOffline().

To be clear: what you have here is that the client is in offline mode.  This is fundamentally different to the vault being offline on the server, although the two things are tied at a practical level.

Thanks !
