There are two RichEdit controls. the received data is displayed in richedit1, and each data is separated by a carriage return. You need to query richedit1 and display the query results in richedit2,

Recently I am working on IM software. I need to insert an expression into RichEdit. The expression is a dynamic GIF image.
Since I have not developed RichEdit before, Baidu has to use OLE technology. That is to say, the inserted images are all OLE objects. RichEdit is an OLE container. The rela
Using animated emoticons in IM is a very interesting way, but it's not easy to choose the right way to do it.In general, in addition to implementing a rich text control yourself, there are currently 3 main solutions:1, use the browser to do the container.2. Use the RichText provided by QT to make containers.3, use RichEdit to do containers.Using the browser to do container benefits is simple to use, the efficiency should also be good (no test, just fe
MSN windowless RichEdit actually uses the COM interface to give an article.
Introduction to the windowless RichEdit
It is a little-known fact that the RichEdit from version 2.0 onwards comes with a COM interface to drive it. to use this interface, you don't need to create a RichEdit window, so it is perfect for applica

I have participated in three im products since my career, and I am mainly responsible for interface library development. As we all know, the im software has a very important control for message display. The implementation method is almost Based on richedit (currently this is the main method, represented by QQ), based on webbrowser (represented: GTalk), there may be WebKit-based, I did not deliberately collect. In many cases, you can e

1. Load richedw.dll
If the RichEdit control is included in the dialog box, you must load the corresponding dynamic link library before creating this dialog box (or before dynamically creating RichEdit). Otherwise, the creation will fail. Different Libraries support different RichEdit versions. The rela
RichEdit is an OLE container that uses RichEdit to display IM chat content, typically using an OLE object to implement an emoticon animation in RichEdit.There are two ways to draw a trigger expression:1. Refresh message from RichEdit.2. Refresh message from the expression animation timer.To refresh the display of an emoticon, you first need to know where the expr
Since the first release, I have received a lot of constructive comments. I would like to thank the netizens weolar and passer-by. They have given me important tips while making me aware of my own arbitrariness. In the previous article, I once said that richedit is a very underlying implementation. In fact, I didn't think so at first, this determination is formed only when almost all desired content can be found in the Win2K leaked code, but the
1. Add the Code related to RichEdit initialization to initinstance ().
Afxinitrichedit ();M_hrichedit = loadlibrary ("richedw.dll ");
(The hmodule m_hrichedit is defined in the corresponding header file)
2. Set the text display style in RichEdit

note the following when using RichEdit: 1. initinstance () of the Program () afxinitrichedit (); 2. To enable RichEdit to automatically wrap text when displaying text, set the following four attributes to horizontal scroll, multiline, and vertical scroll, want return is set to true; the following function is also called to initialize RichEdit: void cstartpa

Recently a lot of friends in Csdn asked how in the RichEdit to achieve superscript subscript, check a lot of data have not found. Today inadvertently wandering in the Delphi area, see a implementation of the superscript, so the article into a CB language posted out.
The following code has been tested for adoption. In the form, place a RichEdit, two button, complete with the following code:

Question 1:Why does RichEditCtrl cause data loss when using DDX for data exchange? Why!When we drag a control to a program, we usually press Ctrl + W to associate a variable with the control using the Class Wizard, and then rely on DDX/DDV for data exchange, if we use the same method to associate RICHEDIT with a CString type variable, there will be a problem, that is, if our data is larger than 64 KB, the data will be lost.According to MSDN, WM_GETTEX
By default, the installed VC ++ 6.0sp6 will have the RichEdit bug modification method.

First of all, these functions support RichEdit2.0 above functions;Secondly, the conventional method is unable to obtain the linespace;
You won't get it using Em_getparaformat, you'll find that the value of dylinespacing is always 0.
You first Em_setparaformat, specify Blinespacingrule = 4, and then use GetParaFormat to fetch dylinespacing is also 0
