Hello djp,
You are correct. Starting in CVI 7, we no longer allowed pasting into indicator cells. From your code, your cells were taking on the state of the column they were in, and the column was set to Indicator mode. The reason you do not see the same behavior in 7.0 is probably because you recreated the .uir in 7.0 and did not set the cells to indicator mode. Therefore, you were able to paste the values in the table.
If you do need the cells to be indicators, you can temporarily change the state before you call ClipboardGetTableVals, then change the state back (as demonstrated below):
SetTableCellRangeAttribute (MainPanel, PANEL_TABLE, VAL_TABLE_ENTIRE_RANGE, ATTR_CELL_MODE, VAL_HOT);
ClipboardGetTableVals (MainPanel, PANEL_TABLE, VAL_TABLE_ENTIRE_RANGE, 0);
SetTableCellRangeAttribute (MainPanel, PANEL_TABLE, VAL_TABLE_ENTIRE_RANGE, ATTR_CELL_MODE, VAL_INDICATOR);
Thanks.
