问题 Navigation systems like the Garmin and TomTom have always fascinated me. I've wanted to implement small map/navigation applications to try out various pathing algorithms and expand on my knowledge of them. This is a two part question: 1.) How is Map data stored? - When you have a network of roads, how is this data generally stored? What parts of the data are retained inorder to reproduce a map later? Is each road stored as a series of points where it changes direction? What kind of file

Closed 3 years ago . Improve this question I want to be able to parse the printer settings binary files that Excel saves inside xl\printerSettings\printerSettingsNN.bin inside the XLSX zip archive. Much searching for documentation avails little. Is this a common format that I just don't recognize, or is it

问题 I'm trying to write a collection of yara signatures that will tag zip files based on artifacts of their creation. I understand the EOCD has a magic number of 0x06054b50, and that it is located at the end of the archive structure. It has a variable length comment field, with a max length of 0xFFFF, so the EOCD could be up to 0xFFFF+ ~20 bytes. However, there could be data after the zip structure that could throw off the any offset dependent scanning. Is there any way to locate the record

问题 The commonly accepted file format for a .url file (internet shortcut) is as follows: [InternetShortcut] URL=http://example.com WorkingDirectory=C:\WINDOWS\ ShowCommand=7 IconIndex=1 IconFile=C:\WINDOWS\SYSTEM\url.dll Modified=20F06BA06D07BD014D HotKey=1601 Is there a way, most likely a hack, to make a single internet shortcut file open up multiple tabs? I tried this: ... URL=http://example.com URL=http://example.com ... and this: ... URL=http://example.com; http://example.com ... and the same

问题 This is my first attempt at reverse engineering, and really, I don't know how to go about it. I have a procedural kind of mind and no foundation of knowledge on popular encryption methods. But, it seems to me, if I have the very minimum data in the correct format, and know that there is an occurrence in the data of a certain word, or words, and where that word begins and ends in the data - that I could somehow discover the method of decrypting the entire file. ----- ENCRYPTED ----------------

问题 Introduction I want to combine my separate Minecraft worlds into a single world and it seemed like a relatively easy feat, but as I did research it evolved into the need to make a custom program. The Struggle I started by shifting the region files and combining them in one region folder, which seemed like the obvious solution and it almost worked. Note: I've opened the files and it seems entire sectors have their coordinates stored, not entities, hence the terrain itself is spatially

问题 This question is somewhat of a long shot, but I've spent hours on it to no avail. I have some code that generates an email file on a webserver, and allows the user to download that email and open it in Outlook. From here, they can make various manual changes to the email before they send it to a bunch of people. Right now, I generate a .OFT file, which is basically an email template. What I want to do is generate a .MSG file, which is an actual email. From a binary point of view, it seems
