Attatching a filter search to a userform

[poobs_away]

OK, so I know how to make a userform, and I kinda know how to make a filter program in VBA, but what I can't figure out no matter where I look is how to attach the two together. Basically what I need is a userform that acts as a search bar for multiple columns, i.e. a userform with three or four bars each attached to its own column (A-D) to filter out whatever keyword you type into the bar in that column.

I don't think this is very difficult, but I've been trying to find a guide on how to do it for the last couple of days and nobody seems to have made one. I'm new to VBA and don't know much coding, so if you post a code, could you also put comments in it telling what the lines do? Thank you.

Oh, and it's important that when it filters out a cell or cells in a column, it brings with it the entire row that cell is in, so that when I find something in A2, it shows everything in row 2, not just the one cell. Thanks
