richtextbox

问题 I'm using a RichTextBox class to make some automatic text formatting. And mz question is, how do I get the RichTextBox to put some string immediately after the caret. When I use RichTextBox.CaretPosition.InsertTextInRun("some string") the text is inserted after the current logical block, but I need to be insterted immediately after the caret, in the middle of a Run block. I hope it's clear, thx very much. 回答1: Well, to insert text after the caret i would do this: richTextBox1.Select

问题 I found the following code http://www.dotnetcurry.com/showarticle.aspx?ID=146 and implemented it into my app, however it only finds the string once and to continue looking for other instances of the string you have to keep pressing the search button (bit tedious with 100's of matches). I'd like to find all instances of the search string and if possible highlight each line, failing that highlight the string item like this code already does but all instances not just one.

问题 This question already has an answer here : C# RichTextBox Highlight Line (1 answer) Closed 3 years ago . I want to highlight the entire line, from start to end doesn't matter whether characters are present or not and line may be blank but it should highlight the complete line. Like 回答1: This will highlight a full line in a RichTextBox if WordWrap is off: void highLightALine(RichTextBox rtb, int line, Color hiLight) { int i1 = rtb.GetFirstCharIndexFromLine(line); int i2 = rtb

问题 Recently, i'm very confused about the RTF format. I check the RTF 1.6 spec from MSDN, which is native supported in .Net. RTF 1.6 will support Unicode by \uN, and for ANSI, RTF will support multiple byte language via codepage. If we use RichTextBox.RTF to retrieve the RTF format, which format will be returned? Unicode? or ANSI multiple byte? System language configuration depended? or anything else? 回答1: String is always Unicode in .NET. 回答2: solved.. That's because we disable RichTextBox

问题 I have (painfully) written a stable console control, but am having a tiny issue regarding when starting the object the Caret is not being set to my custom one until I click inside the control on the form or push a key on the keyboard. I can see that I have focus successfully as the default (very faint line) Caret shows up blinking with no problems, even in spite of me constantly trying to destroy the little bugger. (sorry for condensing some of the code. SO limits to 30,000 characters) Here
