The .NET Framework class library is a library of classes, interfaces, and value types that are included in the Microsoft .NET Framework SDK. This library provides access to system functionality and is designed to be the foundation on which .NET Framework applications, components, and controls are built.
Hi, let´s suppose i have a 3 element´s matrix (boxes dimensions) and i want save the values in it from database, excel,... So, I was thinking do a windows where you select the acquisition method, thus i can make a new modules in future.
How can i make this external module? and call that module in my program?
I dont asking for code only the way to do it
Depending on the language you are using you could make it into a shared or static library, a separate compilation unit or even a separate executable that uses some cross application communication to move the data.
One of these days I'm going to think of a really clever signature.
When you declare the function/sub to be "Shared", it becomes a method of the class, not of an instance! And that means that that method cannot by itself access memebers of an instance of that class. Just ask yourself: when there is more than one instance, which instance should that be? Consequently, you have to pass all instance variables required to that function.
This question is impossible to answer in a forum such as this, and no one is likely to provide "help right from designing till coding". Try a Google search for the subjects that you need to understand in your project, and try the Articles section[^] here on CodeProject.
The first thing you need to do is to approach the client to find out what the requirements are. Find out how the application will actually be used (what the use cases are), and then look to break that down into manageable, easily created chunks. That's how you start.

An OMR application will require a collection of image zones which you compare with supplied images to determine if an acceptable amount of pixels have been provided in any zone to create a 'hit'. There is usually a user interface to address values in a questionable range. Values that make no sense, such as two marks in a row requiring only one mark, must also be resolved by a user, or predefined rule.
Your correct. Sorry it was a long day and for some reason LPT1 was in my head and not printing. I was looking for a way to open and write raw data to parallel port.
Now that I have had a good night sleep, it seems like there is a way to write raw data to printer using the System.Drawing.Printing namespace. If I get time I'll dig out one of my old projects, I think I actually have done raw mode to printer, although it may have been over TCP/IP not parallel port???
I want to make a source code collection to use like a reference
and save tutorial source codes with those information into that collection
and I need somethings like 'Source Code Annotation' Like 'Code tools' of 'Post Message' from this website...
Help me... whatever however about that
I Use VB.Net ...
Thanks, for your reply ...
Maybe if you bothered to read the article you would find out how it worked and how it might be able to help you. You really need to make a bit more of an effort for yourself and not expect to be spoon fed for the rest of your life.
Why is common sense not common?
Never argue with an idiot. They will drag you down to their level where they are an expert.

I wanted to know if I can use Aforge library for YUV display in a GUI that I want to create, I just wanted to know if I can use Aforge for this?,
I have used OpenCV for this, But that is not customizable. Thus exploring other options
