You can remove pictures from cells using three techniques:
1. Assign an empty picture to a cell or range:
VSFlexGrid1.setCellPicture(new Bitmap(0,0));
VSFlexGrid1.setCell(3, new Variant(3), new Variant(3),
new Variant(4), new Variant(4),
new Variant(com.ms.wfc.ui.AxHost.getIPictureDispFromPicture(new Bitmap(0,0))));
2. Use the Clear method to remove all cell formatting:
VSFlexGrid1.Clear(new Variant(1), new Variant(2)); // scrollable area/format
3. Use the setCell property and set flexcpCustomFormat (21) to False. This removes all formatting from a range:
VSFlexGrid1.setCell(21, new Variant(1), new Variant(1),
new Variant(10), new Variant(10), new Variant(0));
