Searching through files

Hi,
I want to develop a windows based desktop application, which is based on the searching pattern as provided by the windows itself.
the features I want are:

• Providing the containing text.

• it should list down the file as it gets the positive result from a file having that word.

• And I should be able to open the file as soon as it gets listed down.

I don;t know where to start from. and one more thing i m developing it in VB 6
if anyone can help me, i'll be thankful

1: get search text & directory from user
2: get listing of directory
3: for each file:
4a: if it's a directory, repeat step 2
4b: if it's a file, open it, look for the word, add it to your list if found, close file
5: display list to user

Search programs are among the easiest to create, though each language does directory listings differently.

try to use Windows API, instead of building from scratch
