combobo for "Existing file Action" is not working

[belmasnaoui]

The combo box in the winform „WinFormsSelfExtractorStub“ does not get updated.
To solve this issue we do need to update the variable „Overwrite“ after changing the selected index.
// c’tor
comboExistingFileAction.SelectedIndexChanged +=(s,e)=> Overwrite = comboExistingFileAction.SelectedIndex;
