Condition Property of CustomAction

[ajeeshco]

Hi,
In a Setup and deployment project i added a dialog called Textboxes (A). In that dialog I have a textbox EDITA1. I would like to know How can I set the Condition Property so that if the user does not enter anything in that textbox the installation should not continue.

To try this from code I created a custom class inherited from Installer but its not working. The code I tried is given below.

Imports System.ComponentModel
Imports System.Configuration.Install

<RunInstaller(True)> Public Class InstallerConfiguration
    Inherits Installer

    Public Overrides Sub Install(ByVal stateSaver As System.Collections.IDictionary)
        MyBase.Install(stateSaver)

        If Context.Parameters("MyTextBox") = String.Empty Then
            Throw New InstallException("Please enter a value!")
        End If

    End Sub

End Class

Thx in advance.

The problem was String.Empty!

The problem was with the comparison . Instead of String.Empty you will have use Nothing.

        If Context.Parameters("MyTextBox") = Nothing Then
            Throw New InstallException("Value is Nothing!")
        End If
