Unclear question; unusable title.

Title is wrong.. question is both unclear and is impossible to answer.

This guy has got two 1 votes, but the question is clear enough to me, and the title is valid - he wants to collect a signature, and compare it to a known example to see if it's the same person.

Trying to take a signature, which is not EXACTLY the same every time, and decide if it's 'the same' is a hugely complex task. There's no way that anyone can tell you how to do that in a forum reply. You should search for articles that cover what you want to do, or perhaps SIGGRAPH papers on the web, which will give you the math, but you'll need to write the code.

Wow - you edited your question so it's TOTALLY different to what you asked in the first place. You create a property on the form which returns the image, and access it from the form class instance. If you don't know how to do that, signature recognition is definitely going to be beyond you, and you should read a basic C# book.

Please don't 'edit' your question to make it mean something totally different to what you asked, it makes the replies make absolutely no sense.

There's nothing wrong with being 'new to C#', but some basic etiquette would help, as would clear questions, and signs that you've read a book, or taken a class, or know how to use google. If you can't return a value from a form without help, there is ZERO chance of you writing a signature recognition system, which, as I said already, is quite an advanced task. Choose something easier while you're just playing and have no teacher or client asking for your work.
