x++ - filter look up in dialog -

-

i have created dialog in class, dialog method below

static void dialog(args _args) { dialog              dialog; dialogfield         dialogfieldcurrentstate; dialogfield         dialogfieldnewstate; custinvoicetable    custinvoicetable;   ;  custinvoicetable = _args.record();    dialog                  = new dialog("change state"); dialogfieldcurrentstate = dialog.addfield(typeid(state_lt),"current state: "); dialogfieldcurrentstate.value(custinvoicetable.state); dialogfieldcurrentstate.enabled(false); dialogfieldnewstate     = dialog.addfield(typeid(state_lt),"new state: ");  if (dialog.run()) {     custinvoicetable.state =  dialogfieldnewstate.value();  }  }

in dialog there 2 fileds current state , new state .now when select new state list of states displayed(irrespective of country) dont want. states respective of country has shown in lookup . need make use of filter e.g. while select while select addressstate addressstate.countryregionid == custinvoicetable.countryregionid; states related country shown.

state_lt here string edt (where put in relation of state_lt) state_lt == addressstate.stateid

in adressstate there method lookupstateid(), how call dialog(code above) ?

i answering last question: "in adressstate there method lookupstateid(), how call dialog(code above) ?" - way writing in capital letters doesn't people understand point better.

it not clear why dialog static method, anyway you'd need following.

let's classdeclaration looks this:

class testclass1 extends runbase {     dialog      dialog;     dialogfield dialogfieldcurrentstate;     dialogfield dialogfieldnewstate;     // etcetera }

your dialog this:

public object dialog() {     ;      dialog = super();      dialogfieldcurrentstate = dialog.addfield(typeid(addressstateid),"current state: ");     dialogfieldcurrentstate.enabled(false);     dialogfieldnewstate     = dialog.addfield(typeid(addressstateid),"new state: ");     dialogfieldnewstate.lookupbutton(formlookupbutton::always);     // if needed      return dialog; }

to implement lookup way want need 2 things. first, open dialog, right click on new state, click setup, , check control's system name. if example fld2_1 need create following method:

void fld2_1_lookup() {     object control = dialog.formrun().controlcallingmethod();     ;      addressstate::lookupstateid(control, dialogfieldnewstate.value()); }

second, necessary override following method:

public void dialogpostrun(dialogrunbase _dialog) {     super(_dialog);      _dialog.dialogform().formrun().controlmethodoverload(true);     _dialog.dialogform().formrun().controlmethodoverloadobject(this); }

that should trick. haven't done while don't think forgot something.

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...
