I am using D10.3. After some assistance from you, I compiled one of my programs the last time in Aug 29, 2020, probably using 9.1.0.
That version successfully compiled lines like the following:
TIELayerPropertiesDlg(Form).IELayerProps.Frame.tabText.TabVisible := true;
I recently tried to fix an unrelated bug and recompile using 10.0.0. Every example of TIELayerPropertiesDlg is now unrecognized. I went back to the last version that compiled in Aug and it, too, does not compile. So, as best as I can tell, I haven't changed anything.
I assume there is something simple that I'm missing. I have searched the ie.inc for possible fixes. I've reviewed the help file. I've searched your change history for compatibility issues. My uses clause includes ieview and iexLayerProps which the help file identifies. I haven't found any fix. Help!
