database - Maximum length for MySQL type text -

-

i'm creating form sending private messages , want set maxlength value of textarea appropriate max length of text field in mysql database table. how many characters can type text field store?

if lot, able specify length in database text type field varchar?

see maximum numbers: http://dev.mysql.com/doc/refman/5.0/en/storage-requirements.html

tinyblob, tinytext       l + 1 bytes, l < 2^8    (255 bytes) blob, text               l + 2 bytes, l < 2^16   (64 kibibytes) mediumblob, mediumtext   l + 3 bytes, l < 2^24   (16 mebibytes) longblob, longtext       l + 4 bytes, l < 2^32   (4 gibibytes)

l number of bytes in text field. maximmum number of chars text 216-1 (using single-byte characters). means 65 535 chars(using single-byte characters).

utf-8/multibyte encoding: using multibyte encoding each character might consume more 1 byte of space. utf-8 space consumption between 1 4 bytes per char.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
