VB.net Prompt user using Windows form
Hi
I have a Windows Form that I use to prompt the user. It is loaded with a list that the user
has to make a selection from.
I have an OK button that then runs the rest of the code.
Is there a way to pause the code, show the form and then run the rest of the code
without havening to channel it through the OK button?
In essence, I want the Windows form to gather feedback just like the OpenFileDialog would in the
following code and gather feedback from the user
With Globals.ThisAddIn.oAUTOMAT
.FileName = ""
.InitialDirectory = System.Environment.GetFold
.Filter = Nothing
'.AddExtension
.ShowDialog()
sFileAndPath = .FileName
sPath = System.IO.Path.GetDirector
sFile = System.IO.Path.GetFileName
oSource_File = sFileAndPath
End With

You need to replace .ShowDialog() with .Show() but ...
That will cause another problem: the line that follows check for .FileName which will be empty at best.
That means that you cannot have code after .Show that is dependant on the result of the dialog box.

Actually, I think he's saying he put the code to continue with...literally in the "OK" button handler.
If that is the case, then what you need actually is ShowDialog(). You'd display the form the gets user input with ShowDialog():
And in frmDialog, you set DialogResult to Ok (it is set to Cancel if the user clicks the "X" in the upper right):

' .... some code ....
Dim dlg As New frmDialog
If dlg.ShowDialog() = DialogResult.Ok Then ' code STOPS here until "dlg" is dismissed by the user
' ... some continuation code ...
' Grab something from "dlg":
' xxx = dlg.yyyy
End If
And in frmDialog, you set DialogResult to Ok (it is set to Cancel if the user clicks the "X" in the upper right):
Public Sub btnOK_Click(...) Handles btnOK.Click
If conditionsAreRight Then
Me.DialogResult = DialogResult.Ok
Else
MessageBox.Show("Please select blah, blah first!)
End If
End Sub
