VB Net - ZelloPTT.dll ptt.dll difference in BeginMessage

[AndyW999]

I have a project using ptt.dll working OK, if I try the same code using ZelloPTT.dll it does not work.

    Dim Users(1) As String
    Users(1) = EveryoneUser
    PTT.BeginMessage(Users)

Using ZelloPTT.dll I get

GetExceptionInfo-System.Runtime.InteropServices.SafeArrayTypeMismatchException(0x80131533): Specified array was not of the expected type.
at System.StubHelpers.MngdSafeArrayMarshaler.ConvertSpaceToNative(IntPtr pMarshalState, Object& pManagedHome, IntPtr pNativeHome)
at ZelloPTTLib.IZelloClient.BeginMessage(Array Users)

Why?

Thanks

Andy.

Hi Andy,
though ptt.dll and zelloptt.dll are not binary compatible, they share COM interfaces nearly 100%,
so the client app code should work when you switch from one version to another
Please share your test project, as we have only C++ and C# sample projects

Hi Eugene Well I thought they should be the same too! Complete project enclosed. I am using VS2013 VB Net. There is a config.dat file in the debug directory that sets the Zello parameters. It’s a bit rough as it is just to get it to work. I have the API’s for various analog and digital radios I wish to integrate it with. On Alex’s suggestion I have been trying the websocket interface and have had some problems there too – I have enclosed the email I just sent to him. Thanks Andy.

Hi Eugene Well there was an attachment sent – maybe your mail system stripped it as it was a RAR containing an exe. I have put it in Dropbox – https://www.dropbox.com/sh/cdxz9dt6o47cj3t/AACWoQZk1TQeHBK7whEyIjLpa?dl=0 Thanks Andy.
