问题 I have a RichTextBox. lets say I want to draw every word "test" in the text.

问题 I'm displaying RTF document in RichTextBox ("upgraded" to RichEdit50W ). Keywords in the document are linked to a webpage using a syntax: {\field{\*\fldinst{HYPERLINK ""https://www.example.com/"" }}{\fldrslt{\cf1 keyword\cf0 }}} I do not want to underline the keywords.

I have experimented with ProcessCmdKey in the form class and onKeyDown and PreProcessMessage in the control class. Here is sample code meant for the control class that should suppress Ctrl+Shift+0 but does not: public override bool PreProcessMessage(ref Message msg) { bool cancel = false; int vKeyCode = (int)msg.WParam;
