VB 6.0 - Help improve OCR, problems with Speed

Alright my recent post I was trying to come up with a function to compare two arrays for my OCR now my OCR is complete it works pretty much perfectly for what I have to do. My friend of mine made an OCR but he used getpixel instead of a picture box and bitblt. Now don't get me wrong my way is fast but his is alot faster. I did a little speed test on mine reading 12 Letters and I get about 40-50 calls per second with no focus and 10-16 calls per second with focus (using it for a game I play). His reads about 250-300 calls per second no focus and about 40-50 with focus. My goal now is to optimize my code so that it gets a sigificant amount of more calls per second.

There's several things I need help with.
1.) I need to fix when it reads the " letter (Look at LineSpace function) Look at the comments in FindLetter Function
2.) Improve how it detects the end of letters (now it's if it's greater than or equal to 9 Line spaces then it's the end)
3.) Make it FASTER! That's my maine goal

Any tips would be greatly appreciated.

Note: I'm a newb so don't laugh at my code lol

I've included a sample project with the code, there are comments on what each sub does but not great detail. Click Get text button to run don't worry about the Store font button.

Thanks,
