I'm having the same problem. As far as I can tell this is some kind
of bug with how matlab interacts with the activex contol's settings
(but i'm no expert). I got around it by using the "formatstring"
property, which automatically sizes the columns to fit the data in
the format string. My setup looks like this:

handles.flexgrid=actxcontrol('VSFLEX.vsFlexArrayCtrl.1',[60 70
250 520]);
handles.flexgrid.formatstring='Name
|<Value ';
handles.flexgrid.highlight=0;
handles.flexgrid.cols=2;

I believe the syntax is identical for msflexgrids.

The formatstring has the two column header names (name and value)
padded with empty spaces to make the columns as wide as I want them.
The | seperates the two columns and the < left aligns the text.

If you had to, you could set up some kind of check to insert enough
spaces to properly size the columns to match the size of the largest
piece of data you're putting in the table. Not the nicest solution,
but it gets the job done.

Hi Richard,

That worked! Pretty simple too, thank you very much. Thank you
everyone else for your assistance as well.
