currently iam using listbox to display content of the INI file..
..is there a way to change the background color of the listbox row to red when the status data is "No Response"?
Too much trouble for that... You would have to subclass Listbox so it will become owner drawn... Instead, I would suggest to use Listview control so you can easily set any color you want for any Item/SubItem.
I've found the flexgrid to be easier to use, and more adaptable than a listview.
You can refer to the textmatrix() for each row and column, without having to separate them, such as you do with a listview.
Take a look at this sample, which lists a few of the features of the flexgrid.
It is easy to bind to a database, or load from a textfile. You can also deal with issues of each cell very easily.
You remove a whole row at a time by moving all the other rows up one, and reducing the total number of rows in the grid. You add rows by moving rows below down by one after you increase the number of rows.
A listbox is better if you have only one field, but if you have multiple fields, and want to use different formats for each field, I think the flexgrid is best.
