I apologize if this is old hat, but I am looking to validate a serial
number. There are two buttons "Next" and "Check Serial", along with a
maskededit box linked to the "Serial_Number" property. When I click the "Check Serial" button it runs the validation DLL which then reads the "Serial_Number" property and sets the "SerialAccepted" property to "1" if success and unsets the property on failure. This "SerialAccepted" property is the condition for enabling and disabling the "Next" button. When I run this setup, everything works; the "Serial_Number" property is read and the "SerialAccepted" property is set to "1". However, the "Next" button remains disabled. If I click back to go to the previous dialog and then forward again the "Next" button is enabled. It appears to be a refresh issue with the button, not that it isn't getting the event. I've spent quite a lot of time on this and just can't seem to pull it off. What am I doing wrong? Example code: <Binary Id="License_Helper" SourceFile="$(env.SETUP_FILES_DIR)\license_helper.dll"/> <CustomAction Id='Test_Serial' BinaryKey='License_Helper' DllEntry='ValidateSerial' Execute='immediate' Return='asyncWait'/> <UI> <Control Id="Next" Type="PushButton" X="236" Y="243" Width="56" Height="17" Text="!(loc.WixUINext)" > <Condition Action=""><![CDATA[SerialAccepted <> "1"]]></Condition> <Condition Action="">SerialAccepted = "1"</Condition> </Control> <Control Id="Check_Serial" Type="PushButton" X="236" Y="203" Width="56" Height="17" Text="Check Serial" > <Publish Event="DoAction" Value="Test_Serial">1</Publish> </Control> <Control Id="Serial_Number_MaskedEdit" Type="MaskedEdit" X="20" Y="100" Width="205" Height="15" Property="Serial_Number"> <Text><![CDATA[<????-????-??-????-????>]]></Text> <Publish Event="DoAction" Value="Test_Serial">1</Publish> </Control> </UI> Log output: Action 12:36:10: <MyProduct>_InputSerialDlg.
