Condition Property of CustomAction

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.

Code Snippet

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.

I don' think MSI sets the property to string.empty. It might be a single space or something that needs trimming before it corresponds to string.empty.

In the properties for that editboxes dialog there'll be a property in uppercase associated with the editbox (it might even be EDITA1). You need to pass that in via CustomActionData as something like:

/ed1=[EDITA1]

and then get the value in your code in ......Parameters.Item("ed1") IIRC the StringDictionary properties.

Hi PhilWilson,

Thanks for the reply. As you said,in my codeI tried to check whether the value is empty or notas follows.

if(Context.Parameters["ed1"] == string.Empty)

{

throw new InstallException("Value can't be null!");

}

But eventhough I don't enteranything in that textbox itis not throwing any exception.

Hi PhilWilson,

Thanks. Now the problem is solved, I'm comparing like this

Code Snippet

If Context.Parameters("MyVariable") = Nothing Then

Throw New InstallException("MyVariable is nothing")

End If
