Functions (Visual Basic for Applications).MyObject.Color = RGB(255, 0, 0) ' Set the Color property of MyObject to Red. Red = RGB(255, 0, 0) ' Return the value for Red. If MyObject does not exist, or if it does not have a Color property, an error occurs. The object MyObject and its property are used for illustration purposes only. It's used for those application methods and properties that accept a color specification. This example shows how the RGB function is used to return a whole number representing an RGB color value. They may be used within the context of Microsoft applications for the Macintosh, but should not be used when communicating color changes directly to the Macintosh operating system. The RGB color values returned by this function are incompatible with those used by the Macintosh operating system. The following table lists some standard colors and the red, green, and blue values they include: Color The value for any argument to RGB that exceeds 255 is assumed to be 255. To set the desired color go to Tools menu and select Options. We can also customize these colors from the Visual Studio Options for Viasfor extension. We can see at line number 30 and 35 the opening curly braces colors have been changed. An RGB color value specifies the relative intensity of red, green, and blue to cause a specific color to be displayed. Now open Visual Studio and see the Text Editor colors. Number in the range 0–255, inclusive, that represents the blue component of the color.Īpplication methods and properties that accept a color specification expect that specification to be a number representing an RGB color value. Number in the range 0–255, inclusive, that represents the green component of the color. Number in the range 0–255, inclusive, that represents the red component of the color. The RGB function syntax has these named arguments: Part Use the colorization information returned by ColorizeLine to repaint and display its text.Returns a Long whole number representing an RGB color value. It also identifies the text span as a particular type of colorable item, such as a comment, keyword, or data type. The ColorizeLine method returns an array of values, one for each letter in the text span being colorized. The VSPackage does this by calling the GetColorizer method on the language service's interface.Ĭall the ColorizeLine method to request that a particular span of text be colorized. Obtain a language service's colorizer object (which implements IVsColorizer and IVsColorizer2). Non-core editor instances can also use a language service's syntax colorization service, but they must explicitly retrieve and apply the service's colorizer, and repaint their document views themselves. Non-core Editor Usage of a Language Service's Colorizer When a language service with a colorizer is obtained by an instance of the core editor, the parsing and rendering of text by a language service's colorizer occurs automatically without requiring any further intervention on your part.Ĭalls the colorizer as needed to parse and analyze text as it is added or modified in the implementation of IVsTextBuffer.Įnsures that the display supplied by the document view provided by the IVsTextView implementation is updated and repainted using the information returned by the colorizer. This method associates the language service with the IVsTextBuffer implementation that the VSPackage uses to manage the text that is to be colorized.Ĭore Editor Usage of a Language Service's Colorizer Obtain an interface to a particular language service by querying the VSPackage's service provider using the languages service's identifying GUID.Ĭall the SetLanguageServiceID method of the object implementing IVsTextBuffer. Use an object implementing IVsTextBuffer to manage the text to be colorized and an object implementing IVsTextView to provide a document view of the text. Colorization RequirementsĪll editors implementing a language service's colorizer must: Visual Studio Environment SDK editors, including the core editor, use language services to identify specific syntactical items and display them with specified colors for a given document view.
