Zip stream implementation with C in embedded devices -


i have embed large text file in limited space of internal memory of mcu. mcu use content of text file purposes later.
memory limitation dos not allow me embed file content directly in code (suppose use character array store file content), if compress content of file (using light-weight algorithm zip or gzip) ok.
suppose mcu uses getbytes(i, len) function read content of array (where i index of begining of required byte & len length of data readed), here problem when compress content & store on device(in character array) can't use getbytes function anymore getting target data, if can write wrapper on top of getbytes function map compressed content requested content, problem solve.
i've no processing limitation on mcu, anymore memory amount limited, & know access content of zip compressed file sequential, don't know possible in acceptable manner using c or c++ in such environment?

it possible in simple , efficient manner.

however, it's better use piecewise compression (at expense of compression ratio) instead of compressing/decompressing entire file @ once, otherwise need store entire decompressed file in ram.

with small piece, compression ratio of strong algorithm not different relatively weak one. recommend using simple compression algorithm.

disk compression algorithms best suited such purposes designed compress/decompress blocks.

c# - DetailsView in ASP.Net - How to add another column on the side/add a control in each row? -

i have detailsview control on page used edit various fields of record, works in respect. i looking way add 1 column (and if works, why not more) right, absolutely read-only, show same fields of record comparison purposes. i aware there no obvious way such thing out of box detailsview . have looked other controls (transposed gridview , recommended formview , listview ), nothing satisfies. have special data binding setup using detailsview , can't out of without losing features. anyone on how "hack in" additional columns (for display only) on detailsview ? the solution have now, use second detailsview , visible set false in aspx. in code, make sure databind hidden detailsview hosts data third column first, initial detailsview named itemdetails . and in item created event, pass third column html rendering of hidden controls (in last code block) : protected void itemdetails_itemcreated(object sender, eventargs e) { if (dataite

i have following script (i use raphaeljs also) draws circle, waits 1 second, draws circle again, etc (you can copy paste - functional, need include raphael raphaeljs.com): <div id="holder"> </div> <script src="raphael.js" type="text/javascript"></script> <script> var paper = raphael(10, 50, 320, 200); var rad = math.pi / 180; var finangle = 0; function sector(cx, cy, r, startangle, endangle, params) { var x1 = cx + r * math.cos(-startangle * rad), x2 = cx + r * math.cos(-endangle * rad), y1 = cy + r * math.sin(-startangle * rad), y2 = cy + r * math.sin(-endangle * rad); return ["m", cx, cy, "l", x1, y1, "a", r, r, 0, +(endangle - startangle > 180), 0, x2, y2]; } var path = sector(100,100,50,0,180); var arc = paper.path(path); function draw() { path = sector(100,100,50,0,finangle);
