Hi guys.

I've been using the Martins VB - A Program Registration Scheme for a while and it works ok.

The problem is its all numbers e.g. -0074612515 I want to make it alphanumeric.

#178

As that link says there is a good app on PSC Unique Serial Number Protection **UPDATED AGAIN - Version 1.5**

This uses multiple textboxes to show different ways to show the code. I've taken out the parts that I want and the app works and compiles. Now when I've tried it recently its giving an Out of Stack Space Error 28.

I haven't changed the code much. There are only 2 functions Invert and iSplit from the PSC app along with a dozen variables, all declared.

I've looked at Monitoring the Call Stack

That says From the View menu, choose Call Stack, there is no Call Stack in the View menu. I've run Debug mode but that doesn't help.

How can I get rid of this Out of Stack Space Error 28?

The main purpose of this app is for a Keygen for another app that checks the hard drive serial number against the serial number they enter in. If valid they have access to all the database, it not they can only see 2000 items. As I've said the PSC app uses multiple textboxes to show different codes. In the main app I want to use a function that checks the serial number is valid. I would have to make an array of what's in the textboxes.
