RDLC To Excel Export, Header and Footer Character Limit -

-
apparently excel hardcoded allow 255 characters in footers (and headers think). naturally wanted put more in footer hence post. header workaround: found putting stuff in rdlc header , setting printsonfirstpage , printsonlastpage true, when exported doesn't put rdlc header items excel header uses split region (with empty excel header) , can put in as like. visually it's ok won't print on every page, presumably use old trick of editing resulting worksheet repeat rows on pages. footer workaround: sadly i've not found similar workaround footer though rdlc footers do put excel footer , mentioned limited 255 characters. this gotcha never imagined when designing reports. anyone got ideas on how around footer character limit? (beyond "create screenshot" is.) note: response this question , , answer footer issue if possible.

Which is the correct text datatype to use in MySQL? -

-
there's varchar, char, text, bigtext, blob... which correct datatype use when storing small text fields (ie. first_name )? "correct" strong word, people use varchar . char option, it's not used in experience. this page explains difference. one of notable differences between char , varchar in latest versions of mysql char incapable of storing trailing spaces (because column automatically padded max length spaces). if store 'abc ' , retrieved 'abc' . might not matter applications, it's keep in mind. similarly, prior 5.03, trailing whitespaces stripped varchar fields before insertion. if need store arbitrary byte values , don't want worry different behaviors between mysql versions, should use 1 of blob types.

according this question can't make service reference address relative. in site, have service reference pointing asmx web service. address is, say: " http://mysite/services/myservice.asmx " unfortunately, if users browse site using: http://www.mysite.com service breaks. i'm assuming silverlight blocking requests because it's seeing www.mysite.com being different domain mysite.com if user browses http://mysite.com , works great. is there way fix this?

when have inner classes private methods or fields compiler has create synthetic package-protected accessor methods allow outer class access private elements (and vice-versa). to avoid that, make fields , methods , constructors package-protected instead of private. but how visibility of class itself? there overhead to private static class { a(){} } versus static class { a(){} } note constructor package-protected in both cases, or making class private change that? have tried compiling , comparing byte code? here results. for: public class example { public static void main(string[] args) { system.out.println("hello world!"); } private static class { a(){} } } the above yields following *.class files: -rw-r--r-- 1 michaelsafyan staff 238 feb 10 00:11 example$a.class -rw-r--r-- 1 michaelsafyan staff 474 feb 10 00:11 example.class now, if move class files, delete private modifier, , recompile, get: -rw
