i have to filter the user input in the comboxbox under my "search tab"
eg. if the user were to type "y", "YAHOO" or any words related to "y" will appear on the filter list and allow the user to select. anyway my combobox values are taken from text file that are stored in local drive.

example of text file :

basically, what are in the text file are the stocks name and its symbol. so just add as and when you like.

ps : please don't recommend using autocomplete. cause it's not what i needed. thanks in advance

Can you describe what it is you want your program to do?

as u can compile and run my code it will form this


what i want is that when i type in A or a in the combo box

it will filter the stock that start with a or A and the list will appear like if i type that it will only show APPLE and not the rest of the stock.
