sql - vb error: Value of type 'String' cannot be converted to 'System.Data.SqlClient.SqlCommand' -

-

i'm novice vb programmer , i'm sure solution trivial, however, getting above error when try display results of 1 of stored procs in sql server doesn't need parameters. how can fix this?

my code excerpt:

dim sqlcmd sqlcommand = new sqlcommand() sqlcmd.commandtext = "exec alltablecount"  sqlcmd.commandtype = commandtype.storedprocedure  sqlcmd.connection = globalfunctions.globalf.getdevsqlserverstoredprocedure(sqlcmd.commandtype)              sqlcmd.executenonquery() msgbox(sqlcmd.executenonquery)

where getdevsqlserverstoredprocedure defined in different file as:

public shared function getdevsqlserverstoredprocedure(byval sql string)    dim dbconn sqlconnection    dim dbcommand sqldataadapter    dim dspagedata new system.data.dataset    dbconn = new sqlconnection(configurationsettings.appsettings("amdmetricsdevconnectionstring"))    dbcommand = new sqldataadapter(sql) 'this line errors on'    dbcommand.fill(dspagedata, "exceptions")    return dspagedata end function

i can see sp vs 2008 in server explorer. problem seems don't know how connect data adapter sp. string query.

command text should name of stored procedure tim mentioned.

it looks problem having passinging commandtype method getdevsqlserverstoredprocedure instead of string.

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

fortran - Function return type mismatch -

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...
