Changing bar colors in bar graph - VBA Excel 2007 -

-

i've created vba excel 2007 program automatically creates bar graphs roi based on 52 different tabs in active workbook. i'm close done, , only thing cannot figure out how change colors of bargraphs.

the graphs created in own subfunction, called call so. every variable changes around whenever it's called.

call addchartobject(1, 1, "example", extraweeks, weekdifference)

my sub calls looks this.

sub addchartobject(j integer, k integer, passedcharttitle string, xtrawks integer, ttlwks integer)      dim topofchart integer      topofchart = 25 + (350 * j)      'adds bar chart total sales      activesheet.chartobjects.add(left:=375, width:=475, top:=topofchart, height:=325)         .chart.setsourcedata source:=sheets("consolidation").range("$a$" & 3 + ((17 + xtrawks) _             * j) & ":$c$" & (4 + ttlwks) + ((17 + xtrawks) * k))         .chart.charttype = xl3dcolumnclustered         .chart.setelement (msoelementdatalabelshow)         .chart.hastitle = true         .chart.charttitle.text = passedcharttitle & " sales"         .chart.setelement (msoelementlegendbottom)         .chart.setelement (msoelementdatalabelnone)         .chart.rightangleaxes = true     end  end sub

the rgb color want use on second series in bar chart (155, 187, 89), per marketing's wishes. i'm pretty sure there .chart.????.???? = rgb (155, 187,89) command can use in set this, have spent far time trying figure out, come nothing.

thanks help!

@scottystyles:

have tried 

.chart.seriescollection([index]).interior.color = rgb(155, 187, 89)

(where [index] placeholder series want change color for)?

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
