c# 3.0 - Trouble installing certificate from .pfx file -

-

i trying install certificate on local machine (win server 2003) x509certificate2 class in c# test console application. when install certificate following code, fine:

var serviceruntimemachinecertificatestore = new x509store(storename.root, storelocation.localmachine); serviceruntimemachinecertificatestore.open(openflags.readwrite); cert = new x509certificate2(certificatepath); serviceruntimemachinecertificatestore.add(cert); serviceruntimemachinecertificatestore.close();

problem is, private key of certificate not persisted, when installed without x509keystorageflags.persistkeyset. tried instanciate certificate (the private key has no password, pass in empty string):

var serviceruntimemachinecertificatestore = new x509store(storename.root, storelocation.localmachine); serviceruntimemachinecertificatestore.open(openflags.readwrite); cert = new x509certificate2(certificatepath, "", x509keystorageflags.persistkeyset); serviceruntimemachinecertificatestore.add(cert); serviceruntimemachinecertificatestore.close();

but trying instanciate certificate throws system.security.cryptography.cryptographicexception "failed load certificate: specified network password not correct.", though private key has no password.

if import certificate in microsoft management console without specifying password works great.

does know how programmatically?

if try create instance of x509certificate2 empty password on windows xp or windows 2003, "failed load certificate: specified network password not correct." exception thrown.

if can, try create certificate password not empty. should fine.

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...
