How to get scroll position for RichTextBox?

一曲冷凌霜 提交于 2019-12-02 07:23:30
I'm working in C#, Windows Forms application, and have a problem getting scroll position for RichTextBox with large amount of text. I'm using this code: public class POINT { public int x; public int y; public POINT() { } public POINT(int x, int y) { this.x = x; this.y = y; } } SendMessage(this.Handle, EM_GETSCROLLPOS, 0, res) But, when control contains large amount of text, resulting y offset is incorect because upper 16 bits of Y are always 0. Is there any way to get scroll position larger than 16 bits? I thought it was about time to case this into an answer GetPositionFromCharIndex(0)

Displaying Raw Data From Image File Using TextBox or RichTextBox?

强颜欢笑 提交于 2019-12-02 06:17:55
问题 My program reads a DDS image file and stores it as a byte array.

Here is a screenshot of how it looks: As you can see only the first few characters are displayed. I am assuming

How to save RichTextBox content in Access2010

只谈情不闲聊 提交于 2019-12-02 06:11:52
I'm creating a dictionary system, where words meaning is editable in RichTextBox (for user define FontSize, Color, etc...) So how to can I save meaning RichTextBox content in the Access database in RTF format? And how to can I read this? Renaud Bompuis Native Rich text in Access 2007/2010/2013 uses a subset of HTML, not RTF, so unless you want to convert to/from RTF<>HTML when you load/save your data, you will have to find another way to store your formatted text. Since the WPF RichText control uses RTF, the best way to save data in an Access database would probably be to use a binary blob. In

How can I prevent system clipboard image data being pasted into a WPF RichTextBox

廉价感情. 提交于 2019-12-02 05:33:29
问题 I have some code in place currently to intercept all Cut, Copy and Paste events into a RichTextBox in WPF. These are designed to strip all content out except plain text, and allow no pasting except plain text (by using a check the Clipboard.ContainsText() method.) This seems to be successful at preventing all such operations from inside the forms. A user can only copy, cut and paste text around, with images / audio data / random junk not being allowed. However, if I use the PrintScreen
