[wix-users] Message Box in Wix Control & Custom Action

[Ronny Eriksson]

I never got that session.Message to work in my C# CA so I just added the 
using System.Windows.Forms
and then used e.g. 
MessageBox.Show("some text", MessageBoxButtons.OK, MessageBoxIcon.Exclamation) 
to show a message box with some texts and that works for my installer at least .

The following code works for me in C++
You can try porting it to C#

    hRecord = ::MsiCreateRecord(1);
    ExitOnNullWithLastError(hRecord, hr, "Failed to create a warning record.");

    hr = WcaSetRecordString(hRecord, 0, szMsg);
    ExitOnFailure(hr, "Failed to set warning record message");

    WcaProcessMessage( INSTALLMESSAGE::INSTALLMESSAGE_WARNING, hRecord);
