Is it hexadecimal or binary? Your screenshot is confusing.

Jibesh 29-Jan-13 18:21pm

you need to explain more about the hex value. what's the logic behind this value and how to operate on this. without much information its just a junk.

Sergey Alexandrovich Kryukov 29-Jan-13 18:34pm

It is junk, yes, but as it looks like a string of the length 64, it should be a conversion to 64-bit integer value. Andi and I answered, please see.

but the screenshot op shared reads the letter 'A' on the screen so I doubt its not a simple conversion i guess

Sergey Alexandrovich Kryukov 29-Jan-13 18:46pm

I see. Well, just one more step, big deal... I don't know why 64-bit then, apparently, it can be interpreted as 8x8 bits, so, 8 byte. But of course, OP needs bitmaps (whatever it is), not stupid strings of '0' and '1', which is just a totally pointless intermediate representation, absolutely redundant.
Pretty bad question, for sure.

"Pretty bad question, for sure"
Yes. I agree that.

Sergey Alexandrovich Kryukov 29-Jan-13 19:09pm

I guess, we tried too hard. OP "answer" is
"I see there are many stupid people who do not realize the purpose, cocky and idiotic gringos"
Do we need such members?

Jibesh 29-Jan-13 19:18pm

his past questions and response also not so good. so its worth thinking about this OP and give a warning though?

It takes a village.

Sergey Alexandrovich Kryukov 29-Jan-13 19:27pm

As I know some Spanish words better then Google Translate, I fixed the translation a bit, to a more adequate translation of the second last work. :-)
And such people usually do not understand warnings.

I tried to warn people many times now, with some limiting success. Usually people who checked themselves after warning were rather overly self-confident, who used to be the most clever boys in their villages, so to speak, but not so ignorant about science and technology. Naturally, they had enough brain to listen to my arguments and check themselves and correct their behavior.

This is absolutely not wonderful: the most rude people are usually among the most ignorant.

Did you delete my solution? solution 7. I believe its spot on.

Sergey Alexandrovich Kryukov 30-Jan-13 3:08am

No, I didn't. And how could it possibly be #7?
—SA

Per Söderlund 30-Jan-13 3:10am

Solution 7
status: deleted.
Is what it says for me.

I wrote that the string 0s and 1s is representing the blue and red squares in the image.
I also think it is a trick question.

Solution 1

If you are sure that the string has exactly 64 "0" and "1" characters, and if you want to store these 64 bits as int64 (i.e. long) you may use Convert.ToInt64 Method (String, Int32)[^].
E.g.

C#

string s = "000000000111000100010010001001111100100010010001001000100000000";
long v = Convert.ToIn64(s, 2);

Of course, it will work, a 5, but it does not teach OP bit operations, which should be the real purpose of this exercise (what else, right?)
So, my answer suggests to do exactly that. Please see.

Thanks for your 5!

Convert, blech, filth.

Use Int64.TryParse (String, NumberStyles, IFormatProvider, Int64)

Andreas Gieriet 29-Jan-13 19:37pm

This does not allow for binary string to long.
I do not like the Convert class, but under the given preconditions of my solution (to be checked upfront), I would use it.

If this a string of bits, it's already a number, there is nothing to convert. I think you are talking about System.String composed of characters '0' and '1' each representing a bit. But this is very simple.

Here is the hint: use the bitwise '<<' operator. Write the code and see if you can achieve it. If you still have a problem, ask a question and tell us where are you stuck.

Another idea is: break your 64-bit value into 8 bytes; that is, define array of 8 bytes, fill bits in each byte from your string in a loop using the input character index and '<<'; and, finally use the class System.BitConverter to convert array of bytes to an unsigned 64-bit value:
http://msdn.microsoft.com/en-us/library/system.bitconverter.toint64.aspx[^].

You can also use signed System.Int64. Apparently, in some cases, the result will be different :-)

This is really simple. Try it.

Good luck,

[After looking at this image:]

You don't need to have this string at all. This is a pointless intermediate representation. You really need to represent a bitmap, say, 7x9. As it does not fit in a array of bytes, it's impractical to keep in in a 64-bit (unsigned) integer value, but you still can, because 63 < 64 :-) I don't think you should bother, because the glyph size can vary, if not now, then in future.

You can use, for example, System.Drawing.Bitmap, with any of the available editors or with one of your own, and store it in a file/stream in a usual way. You can access bit using these methods:
http://msdn.microsoft.com/en-us/library/system.drawing.bitmap.lockbits.aspx[^].

You can extract bits from this bitmap, without any redundant strings. Again, same bitwise operations, which you need to know anyway.
