.NET Communication Library License: Freeware
|
|
| |
Microsoft’s .NET Framework class library doesn’t support certain common communication protocols, for example, the NNTP and POP3 protocols. Although still in its infancy, Smilla’s .NET Communication Library is attempting to fill the gap. By using Smilla’s class library, developers can add NNTP protocol support to their applications for functionalities such as: • Reading newsgroups • Reading common MIME types • Posting new articles (simple text only) • Supporting attachments Developers can therefore write Windows Forms and ASP.NET (Web Forms) client newsreader apps. The library has been written in C#, but is not marked as CLS compliant. It is distributed under the GNU Lesser General Public License and is open source. Further protocols are supposed to be added in the future, eventually residing in separate assemblies.

cryptlib License: Freeware
|
|
| |
Cryptlib by Peter Gutmann is a security toolkit that allows even less experienced programmers to add strong encryption and authentication services to their programs, security features that are becoming more and more indispensable. The library attempts to hide the low-level details of encryption/decryption and authentication from programmers, allowing them to quickly make their projects more secure. Some of the symmetric encryption (private key) and authentication algorithms that cryptlib supports include the following: · AES (Rijndael) · Blowfish · DES, 3DES · RC2, RC4, RC5 The following hash algorithms are available in the library: · MD2, MD4, MD5 · RIPEMD-160 · SHA It offers services such as: · S/MIME · SSL/TLS · ssh It features various hashed message authentication code algorithms: · HMAC-MD5, HMAC-SHA, HMAC-RIPEMD-160 Finally, asymmetric (public/private key) encryption algorithms such as the following are available: · Diffie-Hellman, DSA, RSA cryptlib can also be used with a variety of crypto devices (for example, Fortezza cards and Smart cards). The library is free if used in personal, freeware, or shareware projects. The library is written in C. ActiveX and C++ wrappers are provided. The project is OSI Certified Open Source Software.

CSpot SMTPClient License: Freeware
|
|
| |
SMTPClient from Bossware lets developers add outgoing email capabilities to their Windows Forms and ASP.NET (Web Forms) email apps using the SMTP protocol. The component does not use the .NET System.Web.Mail namespace, which is simply a .NET Framework wrapper for CDONTS and CDOSYS, two Microsoft COM objects. One problem of using System.Web.Mail is that code using this namespace can behave differently depending on the OS of the computer it’s running on. CDONTS is also said to be resource-intensive and more complex to configure, and to have limitations, and even be unstable. The component is written in 100% managed C# and is CLS compliant; therefore, developers can use the component in any .NET Framework programming language, such as C#, VB.NET, J#, ASP.NET, etc. It is a strong-named assembly so it can be used in cross-application development situations by registering it in the Global Assembly Cache (GAC). With this control, developers can implement the following features: • Sending HTML/text messages. • Sending to multiple recipients. • Connecting to multiple servers. • Including multiple attachments. • Connection retry count. • Sending files using MIME encoding. • Synchronized, thread-safe wrapper. • Using message priority. The component complies with several RFC (Request for Comment) documents concerning the SMTP protocol. However, it lacks logging and mail merge capabilities. • distribution agreement (no limits) (optional) • license agreement (no limits) (optional)

FreeTextBox License: Freeware
|
|
| |
Revjon’s FreeTextBox control provides programmers with a user interface element for a WYSIWYG HTML editing environment similar to what is available in word processors. Developers can add text-editing capabilities to ASP.NET (Web Forms) Web pages. Users can therefore edit text and click on buttons to format their text, just like in a text editor. The control is written in C# and has many options for customization. It can be validated using standard ASP.NET validators. The code is not marked CLS compliant, so developers may encounter problems when using it in languages other than C#. MSHTML is reputed to make certain changes to HTML code, such as changing relative URLs to absolute. Developers can prevent this by using the control’s properties. Some developers have noted that it has problems in Opera 7. It lacks find and replace, as well as a context menu.

FTP Component License: Freeware
|
|
| |
Microsoft’s .NET Framework class library contains no classes that will allow developers to access File Transfer Protocol (FTP) services directly. KCommon’s FTP component was designed to compensate for the fact that .NET lacks FTP support. With this FTP component, programmers can build either Windows Forms or ASP.NET (Web Forms) applications that will allow users to send or receive a single file or multiple files, using the FTP protocol. Operations for synchronous and asynchronous (using a callback or an event) transfers are supported. KCommon supports passive mode, but does not support active mode, which could cause problems with poorly written firewalls. Recall that in passive mode, the data flow is set up and initiated by the FTP client, rather than the server. This means improved security for the client computer, because it won’t have to deal with data flow being set up by the server. The component is written in C#. It is not marked as CLS compliant. It does not support proxy servers. The online description erroneously refers to an FtpSession type (it should be Session).

Garbe.Sound Audio DSP License: Freeware
|
|
| |
With Garbe.Sound Audio DSP, a .NET class library, developers can create their own sound filters or use the ones implemented by the author. The author has provided over a half dozen filters, including Gain, Delay, and Reverberation. The library also has the ability to read and write .WAV files, but only in mono. The filters are designed to act like a signal box, with a signal input and output. The library has been written to be as systematic as possible: most classes inherit from the SoundObj class. It is not a strong-named assembly so it can’t be registered in the Global Assembly Cache. Furthermore, the class is not marked as CLS compliant, so developers may encounter problems when using it in languages other than C#. The class library can be used in .NET Framework Windows Forms and Web Forms applications.

Lumisoft UI Controls License: Freeware
|
|
| |
when using Lumisoft’s UI Controls 0.11, developers can choose from over a dozen basic flat controls and add them to their Windows Forms applications. The library includes the following controls: · Label · Button · ToolBar · EditBox · SpinEdit · ComboBox · CheckBox · PictureBox · TabControl · OutlookBar · DateTimePicker With this library, developers can quickly add controls to their applications that would normally involve much more work. For example, developers can take advantage of ButtonEdit, which is the combination of an EditBox and a Button. Other examples of controls this library offers to developers include SpinEdit and OutlookBar controls. However, the library seems somewhat buggy. For example, the code generated when dragging a control (specifically, the wFrame type) onto a Form will not compile: it inserts obsolete code that contains a typographical error. The controls can be configured using the Property tab in Visual Studio .NET, but lack the more advanced WYSIWYG design-time support offered by other control libraries. The code of the library is written in C#. The controls lack databinding capabilities. Some properties don’t seem to have any effect. Limited to one style, unlike other libraries. The toolbar cannot float in applications; namely, it is not dockable.

MenuXP License: Freeware
|
|
| |
CMenuXP is a small set of MFC classes that allow developers to add various graphical user interface elements with an Office XP look to their MFC apps. What this means is that developers can add the flat, non-3D, “water-color” UI controls that were first introduced in Office XP to their MFC applications. These controls do not have raised edges, do not look “pushed in” when clicked, and are not “shadowed” (except for menus). Instead, when elements are selected, they are outlined and shaded. The following classes are included in the library: · CButtonXP: Creates a flat-edged button. · CComboBoxXP: Creates a flat-edged combobox. · CMenuXP: Allows, among other things, icons along the edge of menus · CStatusBarXP: Creates a flat-edged status bar. · CToolBarXP: Developers can easily insert other controls into this toolbar. · CBufferDC: Encapsulates double-buffering to eliminate flickering while drawing. · CImgDesc: A menu item image management class. However, the library has a couple of drawbacks. First, it cannot be used in a language other than C++. Second, it is written using MFC, the Microsoft Foundation Classes library. Although some programmers adore this framework, many find it unwieldy. Of course, the developer who wants to add the Office XP style to applications written using MFC may find that this class library can be of use. But developers starting a new project who are looking for a simpler, more secure library may wish to consider other options.

OpenSSL License: Freeware
|
|
| |
By using the Open SSL 0.9.7c library, developers can write applications that take advantage of Secure Sockets Layer (SSL v2/v3), Transport Layer Security (TLS v1). The Open SSL library uses the included full-strength general-purpose cryptography library, which can be used by itself. Security features such as the following can be implemented: · Data integrity: An application can detect if data has been modified during transmission. · Authenticity: An application can verify the identity of the sender using certificates. · Privacy: An application can ensure that no intermediary between the sender and the recipient can understand the data. Transport Layer Security is an extension of SSL. It is now overseen by an international standards organization. It provides the same capabilities as SSL (data integrity, authenticity, and privacy between client and server), but takes advantage of newer, more advanced cryptographic technology. It is backwards compatible with SSL. The cryptographic library includes a multitude of encryption algorithms. The symmetric, or private key, encryption algorithms offered include Rijndael (now officially the Advanced Encryption Standard, or AES, algorithm of the U.S. government), IDEA, DES, 3DES, RC2, RC4, and Blowfish. The asymmetric, or private/public key, encryption algorithms include RSA, DSA, and Diffie-Hellman. Also included are message digest algorithms such as MD2, MD5, MDC2, and SHA, whose resulting hashes can be used by digital signature schemes to digitally sign documents. The Open SSL library uses some but not all of these algorithms. To compile for the Win32 platform, Perl or compiling under Cygwin is required. Some of the encryption routines/algorithms are covered by patents.

SourceGrid License: Freeware
|
|
| |
SourceGrid 1.2.11.0 is a light grid control written in C# that will allow programmers to add basic grid capabilities to their .NET Windows Forms applications. Apps using the control can display and edit unbound data. The author feels that the DataGrid class of Microsoft’s .NET Framework relies too much on the DataSet class: the control always has to be bound to a dataset or other source for its data. Others consider that the DataSet class is too slanted towards working with XML documents. The SourceGrid control allows simple data to be displayed, without relying on XML to do it. However, while the SourceGrid control is potentially useful for simple applications, it lacks more advanced features offered by other grid controls. For example, SourceGrid lacks databinding. Databinding is the ability to automatically update data from a source that is “bound” to an object, which can mean virtually real-time data access. Without the ability to display bound data, developers must code the data updating themselves, which is costly in time and money. SourceGrid of course provides for unbound data. Any .NET control can be contained in CellControl. The grid control lacks an IDE designer and other advanced WYSIWYG features. It provides no printer support, and lacks grouping and master/detail capabilities.
