I quite like encrypting and I have decided to encrypt .bmp file with some XOR code. But I am still struggling with loading .bmp to Pascal and I don´t know how to i.e read the header of bmp etc. Does anyone know how to do it?
I would appreciate all kind of tips :-)
Thank you very much
It's been a long time since I did any serious Pascal programming, but I found the following wiki and information regarding graphics for you. Take a look at the link below.

So looking through the similar questions section there seems to be a lot of similar questions but none that are helpful in understanding what I need to understand or I'm just generally not getting what they are putting down. I'm studying python and up to the JSON part of it however as I do understand most of it loading, dumping, etc. I am having issues understanding the proper encoding/decoding part of it "json.encoder", etc.
Reading over the python documents, the information there is a little hard for me to understand therefore I can't write my own notes on it. Every site or video I've seen doesn't explain the terms json.encoder and json.decoder but simply just go over loads and dumps.
I have understood everything else till this point, but can't continue till I fully understand it so any help is greatly appreciated.
So my question is:
What are the differences exactly between encoding/decoding using loads/dumps and encoder/decoder?
I'm pretty new to this so I'm not sure if this is a simple request or not but here goes:
I am working on a school website and under each program page is a list of course codes. What I'm looking for is when I click on said course code (ex. HEL2106), to have a lightbox-type of popup that displays program info about said course code. What I have is a .dat file that has all the course codes and descriptions in it, so I would like to use some sort of HTML/CSS/JS that will pop this up and display the correct info about the clicked course from the .dat file.
I'm not 100% sure on how to go about this so if anyone has any suggestions at all, that would be really helpful.
If you need any other details from me, let me know.
Thanks,
(File Info* The .dat file is pretty much just a notepad document with each course code & description in sequence)
Just to let you know, you need to search and learn about a lot of things first.
For data access on a website, you need access to a database. If you don't know about SQL (or any other query language), Query, Database, Tables, Server ... then you should start there.
To read those databases, you need to write code (ASP.NET, PHP, etc) that runs on a web server (Apache, IIS, etc).
If you want to create a website, I recommend you start working with WordPress, Joomla or other CMS (Content Management System) for you to familiarize with a lot of things before jumping to the advance stuff.
YouTube is a very good friend and teacher! :) Start by looking some tutorials there. Hope this will guide you to what you need.
I have no idea what your level of experience is based off your question so I will assume you have a basic understanding of HTML,CSS and JS. If not, then I would recommend Exel Gamboa's answer.
It sounds like you're looking for something like http://fancybox.net/
Of course, it is typically used for displaying images but it could be easily modified for your purpose.
Now about your .dat file. When storing data for large websites, it's typically best to use SQL for databases. This allows you to access data and store it in an organized manner.
As a final recommendation I'd take a look at using a CMS for your website. (Wordpress, WolfCMS, perch, etc...)
Hope this helps.
I have an old SWF project file which is a series of png sequence to produce a 3D tour of numerous stadiums (If you can get it to load http://tinyurl.com/7h2zpcb). When I initially created it I never intended it to be published on the web (it was a university project) however I now would quite like to show it on the internet. The structure is of a main timeline with 4 stadiums each with a png sequence, then, when clicking on one of the stadiums, 4 more png sequences. The only problem is that it is all in one file and is over 12mb, plus has no pre-loader.
It is written in AS3 and is rather complicated as I used movie names and trimming to have reusable functions. It does however have global variables already set-up if this could help.
I have 2 questions. First, is there an easy method of separating out the project movies to 5 individual swf files. i.e main timeline, and each individual png sequence? Or will I need to copy and paste and copy assets over to each FLA file?
Secondly, would it just be easier to try using a preloaded and hoping that users wait for the project to download?
If you have any thoughts on this please give them. Is there a way to optimise the project in another way I am unaware of? As a side note there are a lot of pngs and total over 300mb when combined so I think XML is out of the question?
Thank you for your time. Any suggestions are welcome
For completeness' sake.
I did some research and tests and realised the time it would take to change the project to use any other technology would be too great for my needs. I simply just added a pre-loader to the site and saved myself a lot of extra time. When linking to the site I affix a message explaining that is for an offline installation and there may be a long load-time.
Hopefully this will help others in the future.
Thank you to Marty Wallace, shaunhusain and grapefrukt for their time and advice on this.
I have a program (I own the rights) written in QuickBASIC 3.0, though I do not have anymore the source code.
Anyone know a decompiler that I can use to see what the program does?
Basically it gets some numbers in input and it performs some calculation, showing some results. Nothing too complicated.
Thanks
I haven't seen any publicly available tools but there's a page from a guy who claims to have made one. You could try contacting him.
I wouldn't recommend trying it on your own if you don't have any experience in reversing DOS programs. It seems QuickBASIC 3.0 was compiled into some kind of p-code. I've never seen any research on the DOS-era p-code, but it might bear some relation to the one eventually used in Visual Basic 6.0, and that one has been investigated quite a lot.
If you vaguely remember the idea but don't remember the details (e.g. actual values of coefficients in the formula), one thing you could try is to enter some numbers, read the results, and save them in an Excel sheet. Repeat that a couple of times and try to plot the data. Not much, but might help.
Use the debugger of Borland C++ 3.1, but you are going to need knowledge of assembler...
Any ideas ?
I think the original source was a goldmine database, looking around it appears that the file was likely built using an application called ACT which I gather is a huge product I don't really want to be deploying for a one off file total size less than 5 meg.
So ...
Anyone know of a simple tool that I can run this file through to convert it to a standard CSV or something?
It does appear to be (when looking at it in notepad and excel) in some sort of csv type format but it's like the data is encrypted somehow.
Ok this is weird,
I got a little confused because the data looked a complete mess, in actual fact the mess was the data, that's what it was meant to look like.
Simply put, i opened the file in notepad, seemed to have a sort of pattern so i droppped it on excel.
Apparently excel has no issues reading these files ... strange huh !!!
I am unaware of any third party tooling for opening these files specifically, although there is an SDK available for C# which could resolve your problem with a little elbow grease.
The SDK can be aquired for free Here
Also there is a developer forum which could provide some valuable resources including training material with sample code Here
Resources will be provided with the SDK
Also, out of interest since ACT is a Sage product have you any Sage software floating about which you could attempt to access the data with? Most offices have!
Failing all of the above there is a trial available for ACT! Here!
Good luck with your problem!
