Create a simple standard exe and add 2 forms. On each form add 1 command button

On form1

Option Explicit

Private Sub Command1_Click()

Form2.Show vbModal
End Sub


On form2

Option Explicit
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' private variables declaration
Private Type BROWSEINFO
    HwndOwner As Long
    PidlRoot As Long
    PszDisplayName As String
    LpszTitle As String
    UlFlags As Long
    Lpfn             As Long
    lParam           As Long
    IImage           As Long
End Type
Private Declare Function SHBrowseForFolder Lib "shell32.dll" Alias "SHBrowseForFolderA" (lpBrowseInfo As BROWSEINFO) As Long

Private Sub Command1_Click()
Dim Info As BROWSEINFO
   
    On Error Resume Next
    Info.PidlRoot = &H12
    Info.LpszTitle = "Select Computer Name:"
    Info.UlFlags = &H1000
    Info.PszDisplayName = Space$(256)
    SHBrowseForFolder Info
    If (Asc(Mid$(Info.PszDisplayName, 1, 1)) <> 32) Then
        Debug.Print Left(Info.PszDisplayName, InStr(Info.PszDisplayName, Chr$(0)) - 1)
    Else
        Exit Sub
    End If
End Sub



When I click on form2 button, SHBrowseForFolder starts up and wait for user input.

However, I still can click on form2 and even exit the form1 and let the program hanging there if I don't touch the SHBrowseForFolder. How do I prevent this. I would like the user cannot exit the form1 or form2 without selecting the path
