Hi Guys, This should be simple but I seem to be hitting a brick wall:

I use:

table = uitable('Data',data,'RowNames',rowNames,'ColumnNames',colNames);

I then try:

set(table,'Data',data2)

But I am getting the error "Invalid handle object"

Any thoughts?

Thanks in advance

Tim.

Where is the second piece of code in relation to the first piece?

Strange, because it works just fine here:

RN = {'a','b','c'};
CN = {'col'};
dat = zeros(length(RN),length(CN));
table = uitable('Data',dat,'RowName',RN,'ColumnName',CN);
dat2 = ones(length(RN),length(CN));
set(table,'Data',dat2)

Before you execute the set(table,...) command, set a breakpoint on that line. Then over the mouse over table. Does it give a valid handle number, like 185.2347, or does it say empty or null or something bad like that? Or just type table into the command window and tell us what it says there. It will give the value of table or else say that something's wrong. If it's not a floating point number like I said then you blew it away somehow, perhaps with a call to clear or delete.

Hi Guys, I'm really sorry, It was me being a total fool. I was closing the table before I updated the data. I'm really sorry if I have wasted your time. Thanks for all your help and patience.
