VB.NET TableAdapter 未定义

Question

I'm sure this must be an easy fix, but I haven't been able to see my error. This code worked previously. I'm currently using VS 2019. I'm receiving an error that my tableadapter is not defined.

Dim mbtAdapter As New DataSet1TableAdapters.amongthehiddenTableAdapter
Dim mbtDataTable As DataSet1.amongthehiddenDataTable = Nothing
mbtDataTable = mbtAdapter.GetDataByQuestion(question)

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately. Compiler Error Message: BC30002: Type 'DataSet1TableAdapters.amongthehiddenTableAdapter' is not defined.

Any suggestions greatly appreciated!

Bonjour, je rencontre exactement le même problème depuis VS2017. Je n'ai pas encore trouver comment réparer mon soucis. J'ai constaté qu'il se produisait lorsque l'on utilisait un datagridview et que l'on effectuait une modification sur l'éditeur graphique de ce type d'objet. Le seul contournement que j'ai trouvé à ce jour est de récupérer une version antérieure du programme (ce qui n'est pas satisfaisant, mais faut de mieux...)
