    To be responsive, you shouldn't us a fixed width using px, unless you use media queries to adjust width and html content structure as the device increases or decreases. You are using max-width: on wrapper div, which makes this element responsive up to a specific max-width. Most responsive sites use percentages widths for inner html structure within the fixed width container element, these also will use media queries to change from 3 to 2 to a 1 single column structure for mobile devices. Once this responsive page is working as it should, you can then think about adding all the other features like shopping cart images etc.

    Obviously the left fixed margin length of 1200px will push it out beyond the boundary of browser window when its width starts getting below: 1200px, so you will have to try alternative to using this massive left margin. Again! image is useless in determining to html structure and styling used, its basically gone from a image to a video being supplied to a mechanic to fix a problem. Supply code html/css or a link to this page is a much better option than a image.

    If you have a problem with your car, would you show the mechanics only a picture of the car or bring them the car so they can inspect it and identify the problem.

    Those are diff files. They describe changes to a file. The + and - describe lines that have been added or removed.

    The folder contains a readme file, did you read it? It tells you how to compile it. There's also a FAQ, and there's an index file which describes the other files. If you're talking about files in a directory like contrib, did you read the readme.contrib file? Inside the pascal folder in the contrib folder, did you read the readme.txt file? What if you're writing a program in Pascal and want to use zlib? I can name a file anything I want, it doesn't mean that it's whatever a website says a certain file extension is for, and it doesn't mean that Windows will open the correct program if I just double-click on it. If I rename a picture file with a .adb extension, does that mean that picture is now a database? If you open one of those adb files in a text editor, do you see a database?

    You look for a value that you previously set. If it's not there, set it. The actual value is arbitrary.

    Right. You can only substitute variables in strings, PHP will not recognize an expression inside a string.

    Print $url to see what you're actually setting it to, it does not look like your example output. You should probably also encode those square brackets, they are defined as reserved characters which may be used as delimiters.

    In general, you compile it the same way you compile anything else. You need the source code, any dependencies, and a compiler for whatever language was used to write it.

    You need a script tag for the scrollspy plugin in addition to the jQuery one.

    Every value in a URL or form is a string, so an empty string makes sense if there's no value. If an empty string is a valid value and you need another one, then pick another value that you want to use to represent that or maybe just remove those items from the URL altogether. It's not common to have single quotes in a URL at all though.

    It may be a compatibility issue in using document.getElementById("preview").style = "multiple style properties" to set multiple properties. IT IS advised to use this to set a singular property only, while by using document.getElementById("preview").style.cssText = "multiple style properties" OR document.getElementById("preview").setAttribute('style', 'multiple style properties') is another option.

    Every meaningful sequence of symbols comes from a source that should have documentation that describes how to interpret the symbols in the sequence. If you have a meaningless sequence of symbols, no meaningful information can come from it.

    Leading zeros do not change the value of the number. If you have 789 things, is 0000000000789 a different number? No, it's not, the zeros do not change the number. The hex value would be 0010 0011 0101, those are the three bytes, but if you put those together then you don't need the leading zeros. Also, this only matters if you are treating this as an actual number. Maybe those 2 leading zeros are part of the binary data, which means you would not remove them. If you're going to convert it to a number though, then you don't need leading zeros.

    Well, think about that question. All you have is a sequence of hex digits, right? Is there any other information there? Is there anything other than the actual hex digits? Because if there's not additional information about how to split that up or which digits go with each other, then is there a way to get any other information at all about the hex digits? I mean, take hex out of the equation if you want to. Here, base-10 digits: 513857634343546894648435486743543634 Now, if I tell you that the above is 3 numbers that are concatenated, how do you know what those 3 are? Is there any information in the above series of numbers which is telling you how many numbers there are or where they are separated or anything? What about letters: nauehdncifoendkdusydngkshcufwnwiiaksdhgk Now, that's 3 passwords concatenated. Is there any information there to tell you how to separate those? Why do you think hex is magically different? Why do you think a series of arbitrary hex characters contains some additional information that you're not seeing that would tell you which characters are part of groups?

    I'm not sitting there watching you, but when you are encrypting and decrypting data you are not dealing with "characters", you're dealing with binary data. If you open it in a text editor, the text editor will try to convert it to characters and show those, but it is not character data, it is binary data. You need to understand that, I've been trying to make the point that you are dealing with binary data, not text. If you copy and paste that binary data around you might be losing information depending on how you're copying it, because you're probably copying it from a program that is trying to display it as text. It is not text. It is binary data. Do not treat it like text. When you encrypt data, it does not change each character to a different character, it transforms the entire binary stream. It does not look at the data as a series of characters, it looks at the data as a series of bits. That is how you need to look at it. You keep looking at it like it's text. The encrypted data might not even be the same length as the original data. So, I'm not sure what the purpose of pasting this into a website to count the characters is, and there's no reason to try and paste it here. It's just binary data. The reason you are seeing different characters in different situations is, again, because you are treating it like it's text and it's not. Different programs might display binary data differently, especially if they're treating it like text. The only way to view binary data is in either binary or hex format, which are 2 different representations of the same data. With that text you pasted above, that contains Unicode characters. So, whatever you're using is treating it like Unicode text. Like I said, Unicode is a multi-byte character set. So, some programs might group the bytes into Unicode characters, and others might try to treat it as ASCII and show each byte as a character. That means they will have different lengths. Again, this is because you are treating the data like text when it is not. All of your confusion is due to the fact that you think you are looking at text. You are not. You are looking at a text editor trying to show you binary data, which it was not designed to do. Why would that ever happen? Why would encrypting or decrypting data result in characters that you should ignore? That seems like an awful quality in an encryption algorithm.

    That is how numbers are formatted, leading 0s will always be removed, unless you convert to text string.

    Because it omitted the leading zeros.

    You already said that, but I don't know what you're looking for. What are you searching for? You want a depth-first search, great, what exactly are you searching for? And why do you need recursion? I don't see a recursive structure in your database design, so why do you think you need recursion generally, and depth-first specifically? Is this a homework assignment?

    No. UPDATE is what you use to start an UPDATE query when you are updating the table. It is not a command on its own. You might be thinking of commit, but you only need to commit if you're using transactions, which it doesn't look like you are. When you insert a record outside of a transaction there's nothing else you need to do to actually insert the record, just the insert query will do it. My condolences.

    Gosh, I must be old.Anyone ever here of 'vi' ???Now-a-days I use 'vim' and 'cream'.Vim is a nicer more powerful version of vi. and Cream is the same thing with windoze type menus and a cleaner integration with windows.Jefkin
