This sample uses the new Visual Basic 5 Implements feature to create system callable interfaces. Note: This sample requires the release version of Visual Basic 5.
Using queries and sample data provided by the National Software Testing Laboratories, developers can select a combination of queries, data sources, query methods, and database engine options to explore Visual Basic's data access capabilities.
As tests are completed, DAE displays the time required for each data access option. Those results can be viewed from within the DAE test window or as a text file. You can use the Component Manager to publish components you author to a wider audience.
You can also organize all your components in one place and easily search attributes such as keywords, property values, descriptive text, etc. For example, Active Messaging enables you add script to a Visual Basic application or web site to provide support for creating, sending, and receiving e-mail as well as participating in discussions and other public folder applications. Active Messaging does not represent a new messaging model, but rather is an additional scripting interface to the Messaging Application Programming Interface MAPI model.
The MSChart control has many visible parts, all of which can be programmed. Use the MSChart control's three-dimensional chart features to lend a certain sparkle to a report. In order to see these features, you must either set the ChartType property to a valid 3D type, or set the Chart3D property to True.
The ActiveX Document Debugger provides two drop down combo boxes and two buttons. The comboboxes load a selected ActiveX document into one of three hosts. The buttons start and stop the process. Subclassing is a technique that enables you to intercept Windows messages being sent to a form or control.
By intercepting these messages, you can then write your own code to change or extend the behavior of the object.
VB5 provides the AddressOf keyword, which can be used to reroute Windows messages to your own message processing procedure. Subclassing using the AddressOf is very efficient, but makes debugging a project difficult. If the window you are subclassing receives a message when you are in break mode, VB will crash.
Example of use: Why would a developer want to use this code? Suppose you've created a control which is invisible at run-time, such as a Timer or an ImageList. Such controls often simply display an icon at design time.
If you have a large number of such controls on your form, it can be quite a bit of work to determine which one is which, to make sure that you've set properties on the correct control, etc. With this code, each control will clearly identify itself by name, preventing any such confusion. Take for example, the new-style toolbar buttons: As soon as you move over them, they activate, drawing a border around them. Then, after a pause, they activate at a higher level by showing a ToolTip.
When the mouse moves off, they deactivate, erasing the border and the ToolTip. This sample code helps developers to implement this behavior. IObjectSafety should be implemented by objects that have interfaces which support "untrusted" clients for example, scripts. It allows the owner of the object to specify which interfaces need to be protected from untrusted use.
Examples of interfaces that might be protected in this way are:. OCX sample Visual Basic projects. The application you generate contains a toolbar and a status bar. You can customize the toolbar. The status bar includes information about the status of the application and the date and time.
If you are using a control, you can also create a grid or datasheet type form. Peterson , All Rights Reserved Worldwide.

Do not convert projects using binary compatibility. Binary Compatibility as implemented in Visual Basic 5. This tool only works in an Microsoft Windows NT environment.
The soft button control will paint a specified bitmap, using the user provided mask color. When the button is disabled, it will apply the "embossed" or "disabled" effect to the picture. The soft button only has a 3D edge when the mouse pointer is over it or when it has received focus through keystrokes.
They bridge the gap between the immediate response of an HTML form button, and the smooth, graphical look of a client-side image map. The Dial control has two modes: limited and non-limited. It is used to collect information from a directory tree.
Whenever a file matching the specified criteria is found, it fires an "ItemFound" event. It will continue to walk the tree until either the entire drive is searched, or the fCancel parameter on the ItemFound event is set to True. The seven-segment display can be used to indicate numeric or user-defined values. The application's callback messages are received and processed in a basic module that is registered as a callback function in a Win32 API call by using the new Visual Basic 5.
An "Export To Excel" option is provided for those using Excel. The Component Manager is implemented on the Microsoft Repository. Visual Modeler allows you to fulfill the promise of object-oriented programming by quickly and easily creating applications that are maintainable, have a long lifetime, and are comprised of components that can be reused in other applications. These are the main features of Visual Modeler: Class diagrams where you describe the design of the system you are about to develop in terms of a model, using a high level of abstraction.
Create a form with a sample command link, your own menu, and tab pages with customizable VisualStyle. Create a form with a ribbon-style menu and WinForms data grid.

With GrapeCity WinForms components, along with their effective support, we were able to create and maintain our systems.
Maximum customer satisfaction and extreme usability are our goal, and these tools have been our best partners. Using tools within the Microsoft ecosystem, ComponentOne Studio has extended charting capabilities with advanced features such as trend lines and scaling.
I purchased ComponentOne FlexGrid and it saved my project. These features have turned my project from a test program into a polished professional product with a secure financial future.
We evaluated third-party components from several vendors, and ComponentOne clearly was the best fit for our needs. ComponentOne is the only solution that provided both high quality and performance optimized UI components along with a world-class reporting solution. Robert Collins, President - Brisinger Group.
