Search through database and display results in userform

I have a database of 13 columns and ever increasing rows.
I want the following to be there on my userform.


1 combobox: showing the list of categories from which to search.(The categories are the column headings in columns A1 to A13.The user will have to select one category.

1 textbox:Here the user will enter the search term.

1 Command Button: When the command button is clicked/entered, the code shall be such that it will search in the column corresponding to the category mentioned in the combobox and display the results( The entire 1 row x 13 cloumns containing the search term) in a Listbox. If the search term does not matches then a message box should appear with the message "No entries found"
