The company's system has a new requirement. It is very simple, that is, the colors and fonts of signatures, dates, and texts should be different when the document is presented. This is a simple requirement. However, in practice, it took me a while, isn't it a bit difficult to think about? It is a small deviation. The RichTextBox Control is required for this function, so I wrote a method for adding text to make it simple: Code highlighting produced by

I originally planned to use the word Ole editing function, but I don't know what's going on. The word's RTF editing inserts an image, and the image displayed in RichTextBox is rather vague. I have to change it myself. The exrichtextdemo on codeproject adds the image and text insertion method. Google hasn't found any control that can set the RTF spacing for a long time. The spacing settings and printing are added on the basis of exrichtextbox. Curre

Today, I made a prompt and needed to control the line spacing of text display. I originally wanted to use label for it. Later I found that there are no relevant properties to set. I searched the internet for it, the only method seems to be to control the re-painting by yourself, so I didn't want to use such troublesome processing. So I tried another control RichTextBox and found that there was still no attribute that could be directly set, however, it

Reference: http://blog.iordanov.info /? P = 32 To implement the drag-and-drop function of RichTextBox, you only need to set enableautodragdrop = true to automatically implement it, which is very simple. However, it is a little complicated to implement some personalized control. What I need to implement is: If you drag and drop a file in, you do not want to embed an object connection by default, but upload the file. In other cases, you just want to
