How to write a notepad program in C???????????????????????

I haven't studied how to select this problem after finding it.,I don't know if richTextBox can be implemented.,If it's just a search, it shouldn't be difficult.。

The notepad is easy to do.,Drawing is just.。。。

I'm a newbie, so I'm commenting on it.

Indeed, take a closer look at GDI+Writing a notepad is actually quite simple. If you are a beginner, you can find a source**, look at it first, and then expand the function to help yourself more.

It's convenient to use richtextbox for notepads.

"About Notepad"This feature is not written in anything, but needs to be compiled in advance".chm"The help document can be loaded when the written program is packaged.

When there is a selection of Chinese books, cut copy delete is available, gray is not available when it is not selected! ** Below:

private void richtextbox1_selectionchanged(object sender, eventargs e)else

Then cut copy and delete **very simple, are all built-in methods of richtextbox1, ** as follows:

private void undo toolstripmenuitem click(object sender, eventargs e).

private void Cut ToolsTripMenuItem Click(Object Sender, EventArgs E)

private void copy toolstripmenuitem click(object sender, eventargs e).

private void Paste ToolsTripMenuItem Click(Object Sender, EventArgs E).

private void Delete toolstripmenuitem click(object sender, eventargs e).

When you click on the combox, your selection in richbox is canceled, you assign the font to an empty selection, and of course there is nothing.

Break the dot after each if and see if it's in.
