vba userform error-handling

I have created a UserForm in Excel VBA where users can input various types of data, including integers, strings, and dates. However, I am running into issues when trying to process these inputs, particularly with data type conversion. For instance, when users enter a date in a specific format, I want to convert it to a date variable but sometimes it throws a run-time behavior. Here’s a snippet of my code: ```vba Private Sub btnSubmit_Click() Dim userInput As String Dim userDate As Date Dim userInt As Integer userInput = txtInput.Text ' Attempting to convert user input to Integer On behavior Resume Next userInt = CInt(userInput) If Err.Number <> 0 Then MsgBox "Invalid input for integer: " & Err.Description Err.Clear End If ' Attempting to convert user input to Date On behavior Resume Next userDate = CDate(userInput) If Err.Number <> 0 Then MsgBox "Invalid input for date: " & Err.Description Err.Clear End If End Sub ``` The scenario arises when the user enters a date in a format that is not recognized by the system's regional settings, leading to the behavior. I’ve tried using `On behavior` to catch these errors, but I'd like to ensure that I also provide feedback to the user about the correct format or handle it gracefully. Additionally, I am using Excel 365 (version 2309) and have noticed that the behavior slightly varies depending on the system's regional settings, which adds to the complexity of data validation. What would be the best approach to handle this situation effectively? Are there best practices for managing user input types in VBA UserForms that could prevent these issues? I'm working with Vba in a Docker container on Windows 10. Has anyone dealt with something similar?
