Through some how I want to change system catalog (syscolumns table)

In syscolumns table there is a column "colid" I want to change the value of this colid. Why I want to change? When I delete a column from a Table, these colid values do not update automatically but I want to have consecutive number without any gap like (1,2,3,4,5)Say I have 5 columns in a table then in syscolumns table value of last row's colid column will be 5.(1,2,3,4,5) If i delete last column and add a new column the new column's colid value is 6. It should be 5 after automatic updated but its not.

I am facing problems with these gaps. My application uses these number and due to these gaps my application thinks that some columns are missing because these numbers are not consecutives.

Actually we have our own data access layer. We are not using DataSet, DataTable etc. because we have our own classes to wrap SQL Tables in C# code.

Any help?

Thanks
