使用VB6在RichTextBox中加载RTF文件时出现问题

我有一个RTF显示在RichTextBox中，该程序可以加载文件，但不能全部加载.
并非全部，因为当我在写字板中打开文件时，缺少的文本在那里.我尝试在Internet上进行搜索，但是找不到解决办法.

任何人都可以发表这种情况的原因.

最初，RTF文件是在图像中解析的.该图像具有背景和数据.
当我尝试在Microsoft Word中打开RTF时，该图像与原始图像几乎相同.

I have a RTF that displayed in RichTextBox, The program can load the file but not all.
Not all because when I opening the file in WordPad the missing text is there. I try searching it in the Internet but I have no luck finding the solution.

Can anyone post why this happens.

Originally the RTF file is parsed in image. The image has a background and data.
When I try opening the RTF in Microsoft Word, the image is almost same as the original image.
