Windows form architecture

Configuration namespace; these are described in Application Settings Attributes. When you define a setting, you must apply it with either ApplicationScopedSettingAttribute or UserScopedSettingAttribute , which describes whether the setting applies to the entire application or just to the current user. The following code example defines a custom settings class with a single setting, BackgroundColor.

The ApplicationSettingsBase class does not itself persist or load settings; this job falls to the settings provider, a class that derives from SettingsProvider. If a derived class of ApplicationSettingsBase does not specify a settings provider through the SettingsProviderAttribute , then the default provider, LocalFileSettingsProvider , is used. The configuration system that was originally released with the.

NET Framework supports providing static application configuration data through either the local computer's machine. The LocalFileSettingsProvider class expands this native support in the following ways:.

Application-scoped settings can be stored in either the machine. User-scoped settings can be stored in app. Non-default user-scoped settings are stored in a new file, user. You can specify a default for a user-scoped setting with DefaultSettingValueAttribute. Because user-scoped settings often change during application execution, user. All three configuration files store settings in XML format.

An app. For a definition of the elements within the application settings section of a configuration file, see Application Settings Schema. Application settings uses the Windows Forms data binding architecture to provide two-way communication of settings updates between the settings object and components.

If you use Visual Studio to create application settings and assign them to component properties, these bindings are generated automatically. You can only bind an application setting to a component that supports the IBindableComponent interface. Also, the component must implement a change event for a specific bound property, or notify application settings that the property has changed through the INotifyPropertyChanged interface. If the component does not implement IBindableComponent and you are binding through Visual Studio, the bound properties will be set the first time, but will not update.

Here with the stored procedure, there is no problem and and from SQL Server I can insert data into table easily. But from windows form, it does not insert data in table. Plz help me. Your middle tier consists of classes holding the values you require in properties. Instead of writing the data access manually, try using the Entity Framework EF which does that for you. Here at MSDN you can find a quickstart example which shows you how you can use it.

Instead of mapping the fields manually and executing a query, the Entity Framework does that which means you just have to assign the values to the object's properties and call SaveChanges - the SQL code is created and executed automatically by the EF.

Swap them in and out of your main form JFrame. The details are a wee bit tricky, you do have to manually dispose a user control if you swap it out. Check this thread for a code sample. Hans Passant.

Wednesday, September 30, PM. You can display it with various border styles, and you can use it to represent and activate operational states.

You can also define it to have the focus by default. The ToolStripLabel is like a ToolStripButton that does not get focus by default and that does not render as pushed or highlighted.

ToolStripLabel as a hosted item supports access keys. The ToolStripSeparator adds a vertical or horizontal line to a toolbar or menu, depending on the orientation. It provides grouping of or distinction between items, such as those on a menu. You can add a ToolStripSeparator at design time by choosing it from a drop-down list. However, you can also automatically create a ToolStripSeparator by typing a hyphen - in either the designer template node or in the Add method.

ToolStripControlHost can host other controls, including custom controls, in two ways:. To fully access the hosted control and properties, you must cast the Control property back to the actual class it represents. Extend ToolStripControlHost , and in the inherited class's parameterless constructor, call the base class constructor passing a class that derives from Control.

This option lets you wrap common control methods and properties for easy access in a ToolStrip. A subset of the hosted control's properties and events are exposed at the ToolStripComboBox level, but the underlying ComboBox control is fully accessible through the ComboBox property. A subset of the hosted control's properties and events are exposed at the ToolStripTextBox level, but the underlying TextBox control is fully accessible through the TextBox property.

A subset of the hosted control's properties and events are exposed at the ToolStripProgressBar level, but the underlying ProgressBar control is fully accessible through the ProgressBar property.

Access these drop-down items directly through the DropDownItems property. Hide or show the drop-down arrow by setting the ShowDropDownArrow property. ToolStripSplitButton combines button and drop-down button functionality. Use the DefaultItem property to synchronize the Click event of the chosen drop-down item with the item shown on the button.

ToolStripItem provides the following generic features and options to inheriting controls:. ToolStripItem controls receive their own click, mouse, and paint events, and can perform some keyboard preprocessing also. Use images in ToolStrip controls by setting these properties directly or by setting the run-time—only ImageList property. Image scaling is determined by the interaction of properties in both ToolStrip and ToolStripItem , as follows:.

ImageScalingSize is the scale of the final image as determined by the combination of the image's ImageScaling setting and the container's AutoSize setting. The value of the Alignment property determines the end of the ToolStrip at which an item appears. The Alignment property works only when the layout style of the ToolStrip is set to one of the stack overflow values.

Items are placed on the ToolStrip in the order in which the items appear in the Items collection. To programmatically change where an item is laid out, use the Insert method to move the item in the collection. This method moves the item but does not duplicate it. The TextImageRelation property defines the relative placement of the image with respect to the text on a ToolStripItem.

Items that lack an image, text, or both are treated as special cases so that the ToolStripItem does not display a blank spot for the missing element or elements. DisplayStyle allows you to set the values of an item's Text and Image properties while displaying only what you want. This is typically used to change only the display style when showing the same item in a different context.

ToolStripManager supports ToolStrip -related tasks for entire applications, such as merging, settings, and renderer options. ToolStripRenderer allows you to apply a particular style or theme to a ToolStrip easily. ToolStripContainer is similar to SplitContainer. It uses four docked side panels instances of ToolStripPanel and one central panel an instance of ToolStripContentPanel to create a typical arrangement.

You cannot remove the side panels, but you can hide them.
