The device context of the device you plan to use to print the contents of the control. If text is selected in the RichTextBox control, the SelPrint method sends only the selected text to the target device.
If no text is selected, the entire contents of the RichTextBox are sent to the target device. Rather, it sends a copy of formatted text to a device which can print the text. For example, you can send the text to the Printer object using code as follows:. Notice that the hDC property of the Printer object is used to specify the device context argument of the SelPrint method. Note If you use the Printer object as the destination of the text from the RichTextBox control, you must first initialize the device context of the Printer object by printing something like a zero-length string.
The SelChange Event. Occurs when the current selection of text in the RichTextBox control has changed or the insertion point has moved. You can use the SelChange event to check the various properties that give information about the current selection such as SelBold so you can update buttons in a toolbar, for example. Sample Application. The sample application for this article uses the RichTextBox control to implement a WordPad-like text editor see the screen shot below :.
This article does not contain a "blow by blow" description of the code for the sample application, but much can be learned by downloading the sample application and working with it. The sample application incorporates many of the features of the RichTextBox discussed earlier in this article, and also incorporates the use of menus and controls discussed in the topics preceding this one Toolbar, CommonDialog, StatusBar.
Also, many of the concepts and techniques used for the File and Edit menu commands in the previous topic on building the basic text editor have been incorporated here. Development of this sample application was not as straightforward as I would have hoped. Most of the trouble stemmed from the fact that the RichTextBox has built-in capabilities for basic text editing such as support of keyboard shortcuts like Ctrl-X and Ctrl-V for cutting and pasting , causing conflicts when attempting to implement keyboard events and menu Edit commands such as keyboard shortcuts not working at all, "double pasting", etc.
Related to cutting and pasting is the Clipboard object, which I could not get to always "do the right thing" when a mixture of text and graphics was involved. These issues were resolved by using a custom Clipboard class in lieu of the Clipboard object, and by using the API technique of subclassing to intercept some of the keyboard shortcuts.
The sample application is a robust demo that shows you how to use many of the RichTextBox's features, as well as providing a "workout" with menus, the Toolbar, and the Common Dialog controls. Features that are not present in the sample application are advanced paragraph formatting and tab-setting.
If you were inclined to enhance this application, that would be a good place to start. In addition, you would have to come up with a way to display a ruler possible suggestions for the ruler include using a PictureBox in conjunction with labels or lines, or by finding a freeware custom control.
Download the project files for the sample application here. The RichTextBox Control The RichTextBox control allows the user to display, enter, and edit text while also providing more advanced formatting features than the conventional TextBox control. General Description The RichTextBox control provides a number of properties you can use to apply formatting to any portion of text within the control.
HideSelection Returns a Boolean value that determines whether selected text appears highlighted when the RTB loses focus. MaxLength Returns or sets a value Long indicating whether there is a maximum number of characters a RichTextBox control can hold and, if so, specifies the maximum number of characters.
RightMargin The RightMargin property is a Long value used to set the right most limit for text wrapping, centering, and indentation. ScrollBars Returns or sets a value indicating whether the RTB has horizontal or vertical scroll bars. SelAlignment Returns or sets a value that controls the alignment of the paragraphs in a RichTextBox control. SelAlignment Then ' Code to run when selection is mixed. ElseIf RichTextBox1. SelBold Then ' Code to run when selection is mixed.
End If SelBullet Returns or sets a value that determines if a paragraph in the RichTextBox control containing the current selection or insertion point has the bullet style. SelBullet Then ' Code to run when selection is mixed.
End If SelCharOffset Returns or sets a value that determines whether text in the RichTextBox control appears on the baseline normal , as a superscript above the baseline, or as a subscript below the baseline.
SelCharOffset Then ' Code to run when selection is mixed. SelFontName Returns or sets the font used to display the currently selected text or the character s immediately following the insertion point in the RichTextBox control.
SelFontSize Returns or sets a value that specifies the size of the font used to display text in a RichTextBox control. SelIndent, SelRightIndent, SelHangingIndent Returns or sets the margin settings for the paragraph s in a RichTextBox control that either contain the current selection or are added at the current insertion point. SelProtected Returns or sets a value which determines if the current selection is protected.
SelStart — returns or sets the starting point of text selected; indicates the position of the insertion point if no text is selected. SelText — returns or sets the string containing the currently selected text; consists of a zero-length string "" if no characters are selected.
When working with these properties: Setting SelLength less than 0 causes a run-time error.. Setting SelStart greater than the text length sets the property to the existing text length; changing SelStart changes the selection to an insertion point and sets SelLength to 0.
Setting SelText to a new value sets SelLength to 0 and replaces the selected text with the new string. SelRTF Returns or sets the text in.
Syntax object. Syntax: RichTextBox1. LoadFile pathname, filetype Where pathname is a string defining the path and filename of the file to load into the control and filetype is an integer or constant that specifies the type of file loaded.
SaveFile pathname, filetype Where pathname is a string defining the path and filename of the file to receive the contents of the control and filetype is an integer or constant that specifies the type of file to be saved. Find Searches the text in a RichTextBox control for a given string. Find string, start, end, options The Find method syntax has these parts: Part Description object Required.
The RTB control. Settings The setting for options can include: Constant Value Description rtfWholeWord 2 Determines if a match is based on a whole word or a fragment of a word. Remarks If the text searched for is found, the Find method highlights the specified text and returns the index of the first character highlighted.
This table describes the possible behaviors: Start End Search Behavior Specified Specified Searches from the specified start location to the specified end location. Specified Omitted Searches from the specified start location to the end of the text in the control.
Omitted Specified Searches from the current insertion point to the specified end location. Omitted Omitted Searches the current selection if text is selected or the entire contents of the control if no text is selected. GetLineFromChar charpos Where charpos is a long integer that specifies the index of the character whose line you want to identify. Span Selects text in a RichTextBox control based on a set of specified characters.
Settings The settings for forward are: Setting Description True Default Selects text from the current insertion point or the beginning of the current selection forward, toward the end of the text.
False Selects text from the current insertion point or the beginning of the current selection backward, toward the start of the text.
