Screencast: Control Microsoft Excel with Visual APL and VSTO

2007-03-22T11:31:00Z

Original broadcast date: March 14th, 2007

Controlling Excel using VSTO

With the Visual Studio Tools for Office Visual Studio Add-in, you can control all aspects of any and all applications in the Microsoft Office Suite of products.

This Screencast highlights the use of VSTO to control and design an Excel workbook.

Using VSTO, your development experience in Visual Studio will be just as though you are developing your application in Excel.

Using the VSTO Excel templates, you have full access to all features of Excel as you develop, just as though you were actually in Excel as you were creating your applicaton!

Visual APL is a 100% managed code .Net language, with full integration with Visual Studio. A large part of this integration is the ability to seamlessly cross language bounderies when programming your Solution in Visual Studio. This webcast will show how to use the VSTO templates for C# as the front end of your VSTO application, with Visual APL powering the back end calculations of the workbook operations!

Using the VSTO templates, you can visually design your workbook with Visual Studio designer interfaces, just as you would design a Form for a Windows project using the Visual Studio Forms Designer.

Screencast: Session Integration, script editing features, and edit variables as XML

2007-03-21T23:44:00Z

Original broadcast date: Feb 28th, 2007

Technologies presented in this screencast:

The session in Visual APL is tightly integrated with Visual Studio, making the process of prototyping and testing code only a keystroke away with the Cielo Explorer.

The creation and organizing of script files used with the Cielo Explorer is also tightly integrated with the Solution Explorer via the CieloSession project type, allowing the developer to take advantage of all features they are accustomed to for arranging and partitioning files in their Visual Studio Solutions. By using multiple CieloSession projects, you can choose which project will be the active project back-end of your Cielo Explorer.

Visual APL allows developers to modify complex array and data structures via the built-in ")xmlout" session command, and modifications made by the developer to the variable in XML form can be saved back to the session for further testing and experimentation. Variables edited using the ")xmlout" command automatically appear in the active CieloSession project as XML data files. You can also load XML data files created during previous editing sessions, allowing data to be persisted across opening and closing Visual Studio.

Screencast: The using directive, and []Reference and []Using

2007-03-04T04:24:00Z

Examples presented in this screencast:

Most .Net languages only allow the importing of .Net assemblies at build time. This means that you can only use the classes, methods, properties, events, etc, of assemblies which exist, on your computer, at the time you build your assembly with Visual Studio. Here is a common example of referencing an assembly:

refbyname System.Windows.Forms
using System.Windows.Forms

In Visual APL, you can also import assemblies at runtime using the []reference and []using expressions. By using these system functions, the importing of the specified assemblies is only performed at the moment the []reference or []using function is executed, making it possible for your code to import assemblies that do not or cannot exist at the time you build your assembly. Here is the runtime equivalent of the System.Windows.Forms directive import above:

⎕reference "System.Windows.Forms"
⎕using "System.Windows.Forms"

Screencast: The Using Statement

2007-03-04T04:09:00Z

Examples presented in this screencast:

The using statment has an entirely seperate functionallity from the using directive, but has a somewhat similar syntax. Here is an example showing the difference between the using directive and using statement:

// The using directive
using System.IO

// The using statement
using (stream = File.Open("c:\testfile.txt", FileMode.Create)) {
// some code
}

The purpose of the using statement is to ensure that each argument variable to the statement is disposed of after the statement has completed execution. In the above example, this would mean that the "stream" variable would be disposed of, or have its system resources released, once execution reached the closing brace of the statement.

Examples presented in this screencast:

refbyname System.Windows.Forms
using System.Windows.Forms

⎕reference "System.Windows.Forms"
⎕using "System.Windows.Forms"

Next in the screencast is the Using statement. The using statment has an entirely seperate functionallity from the using directive, but has a somwhat similar syntax. Here is an example showing the difference between the using directive and using statement:

// The using directive
using System.IO

// The using statement
using (stream = File.Open("c:\testfile.txt", FileMode.Create)) {
// some code
}
