Microsoft code library

Generally, a download manager enables downloading of large files or multiples files in one session. Many web browsers, such as Internet Explorer 9, include a download manager. Stand-alone download managers also are available, including the Microsoft Download Manager.

The Microsoft Download Manager solves these potential problems. It gives you the ability to download multiple files at one time and download large files quickly and reliably. It also allows you to suspend active downloads and resume downloads that have failed. Microsoft Download Manager is free and available for download now.

Excel macro codes can be used to automate regular Excel tasks and prevent you from performing them manually.

This results in time saved and more reliable work. These codes are perfect for beginners who have not used Excel VBA before , or are just starting out. Let us first describe what a macro code is and how you can start using them.

Then we will get to the exciting part and explore the Excel macro examples in this list. You can create macros in Excel by either recording the steps you want it to perform the VBA is written for you , or by writing the VBA yourself. The VBA code can be simple, and perform a basic formatting step or freeze panes. Or it could do something greater such as export all sheets of a workbook as a separate PDF.

This saves you from having to create them yourself, but is also a great way to begin learning VBA. Using the macro codes require just a simple copy and paste. However, you need to ensure that you paste them to the correct place. The Visual Basic Editor opens. The Project Explorer window is shown on the left. It lists the open workbooks and other projects. In this VBA code library, there is a category named Events. These macros will not be stored in modules, but in the object where the event occurs.

This will be explained when we present the code. The majority of the macros in this list are stored in modules and follow the procedure explained above. Although it is possible to run the macro from the macros window. Assigning the macro to a button that you can click, will make it easier to run your macros. You can insert buttons on the Quick Access Toolbar where the Save and Undo buttons reside , the Ribbon, or onto a worksheet.

For this example, we will show you how to add a button to the Quick Access Toolbar to run your macros. The button will appear on the Quick Access Toolbar and will run your macro when clicked. The macro code examples in this list have been split into categories to make it easier to find those that you are interested in using.

This code will automatically fit the widths of specific columns on a worksheet. In this example, it is columns D and F. Copy and paste is one of the most common actions in Excel. It can be written with just one line of VBA code. You may not have a specific range to paste the content into. Often you are trying to append the copied data to the bottom of another list. This code copies the used range around cell A2 and pastes it to the first empty cell at the bottom of column A on a sheet named Archive.

Finally, you may want to use some of the paste special options available in Excel. To access these in VBA, we will separate the copy and paste operation into two statements. Formatting cells that contain formulas makes them easy to identify on a worksheet. It declares a range variable named rng and uses it to loop through each cell that contains a formula. Another common action with formulas is to convert them into values.

This VBA code will do this for all formulas on the worksheet. Hiding columns is great for reducing worksheet clutter and protecting data.

This macro code will unhide all the hidden columns with the click of a button. You may want to take this further and assign a password or specify actions to be allowed. This macros code assigns the password Excel and allows the inserting of rows only. If you know worksheet protection well, you will know that there are various actions that you can allow or prevent. And we can do this with our VBA code. A common reason to protect a worksheet is to save your formulas from accidental damage.

This code will protect only cells on a worksheet that contains formulas. It begins by unprotecting the sheet and unlocking all cells. It then locks those containing formulas before applying protection. It is simple to set up a loop to perform an action to all the worksheets of a workbook. You can insert any action you require. In this example, we protect the worksheets. Replace the line ws.

Protect with the actions that you require. On macOS you can also use Homebrew. NET library is available as a multiplatform NuGet package. Microsoft SEAL has no required dependencies, but certain optional features can be enabled when compiling with support for specific third-party libraries. When building manually , one can choose to have the Microsoft SEAL build system download and build the dependencies, or alternatively search the system directories for pre-installed dependencies.

On the other extreme, the downloadable NuGet package cannot be configured at all, but it is always possible to build a custom NuGet package. Other package managers offer varying amounts of opportunities for configuring the dependencies and other build options.

The optional dependencies and their tested versions other versions may work as well are as follows:. Intel HEXL is a library providing efficient implementations of cryptographic primitives common in homomorphic encryption. Microsoft GSL Guidelines Support Library is a header-only library that implements gsl::span : a view type that provides safe bounds-checked array access to memory. ZLIB and Zstandard are widely used compression libraries.

Microsoft SEAL can optionally use these libraries to compress data that is serialized. One may ask how compression can help when ciphertext and key data is supposed to be indistinguishable from random.

When using the CKKS scheme in particular, these prime numbers can be quite small e. Therefore, it is not uncommon that almost half of the ciphertext bytes are zeros, and applying a general-purpose compression algorithm is a convenient way of getting rid this wasted space.

Note: The compression rate for a SecretKey can in theory at least reveal information about the key. If this is a concern, one can always save the SecretKey in an uncompressed form. Simply add this package into your. NET project as a dependency and you are ready to go. Using Microsoft SEAL will require the user to invest some time in learning fundamental concepts in homomorphic encryption.

The code comes with heavily commented examples that are designed to gradually teach such concepts as well as demonstrate a large fraction of the API. It is recommended to read the comments and the code snippets along with command line printout from running an example. For easier navigation, command line printout provides the line number in the associated source file where the associated code snippets start.

NET Components C. They are designed to provide the reader with the necessary conceptual background on homomorphic encryption. Reusing code directly from the examples will not work well, as the examples are often demonstrating individual pieces of functionality, and are not optimized for performance.

Writing Microsoft SEAL code without studying the examples in depth will inevitably result in code that is vulnerable, malfunctioning, or extremely slow. When studying the examples above, it will become clear that the CKKS scheme can be unfriendly to beginners. Even relatively simple computations can be challenging to get to work due to the limitations of the rescaling operation and the requirement of aligning scales at different levels.

We have created a new compiler tool called EVA that helps resolve these challenges to a large extent. EVA allows programmers to express desired encrypted computations in Python. It optimizes the computations for Microsoft SEAL, selects appropriate encryption parameters, and provides a convenient Python API for encrypting the input, executing the computation, and decrypting the result.

EVA is available at GitHub. Try it out, and let us know what you think! There are no immediate plans to support the BFV scheme. We recommend using out-of-source build although in-source build works. Below we give instructions for how to configure, build, and install Microsoft SEAL either globally system-wide , or locally for a single user. A global install requires elevated root or administrator privileges.

You can build the Microsoft SEAL library out-of-source for your machine by executing the following commands:. Various configuration options can be specified and passed to the CMake build system. On Windows the same scripts above work in a developer command prompt for Visual Studio using either the Ninja or "Visual Studio 16 " generators. When using the Ninja generator, please use the appropriate command prompt depending on the platform you want to build for.

If you want to build for x64, please use the x64 Native Tools Command Prompt for Visual Studio command prompt to configure and build the library. If you want to build for x86, please use the x86 Native Tools Command Prompt for Visual Studio command prompt to configure and build the library. To build using Ninja, type. When using the "Visual Studio 16 " generator you can use the Developer Command Prompt for VS command prompt to configure and build the library.

By default the generated platform will be x Installing the library in Windows works as well. Instead of using the sudo command, however, you need to run cmake --install build from a command prompt with Administrator permissions. Skip to main content. This browser is no longer supported.
