Modify a Binary file(an after effect project file) in c# or c++
<p>I need to change some text values inside an after effect project file that I assume it's a binary file. You cannot edit this file with a text editor, if you do next time you open it you will encounter the error message about corrupted project file.</p>

<p>So i need to for example change "TextArea1" to "Some new text" so as you see the length of the new text is not the same as the original one. should i use BinaryReader or something? how can i find the original String in Byte[] Array i get from this command...</p>

<p>As I'm a newbie in this field please tell me what should I do in this matter.</p>
