i following this article (in there link .cs file @ bottom of page) generate self-signed x509certificate2 . code in article works want extend it. trying pass optional argument, _in_opt_ pcrypt_algorithm_identifier psignaturealgorithm , certcreateselfsigncertificate . i have created structure it: struct cryptoapiblob { public int32 cbdata; public intptr pbdata; } struct cryptalgorithmidentifier { public string pszobjid; public cryptoapiblob parameters; } the code trying use create is: cryptalgorithmidentifier algorithm = new cryptalgorithmidentifier { pszobjid = "szoid_nist_aes256_cbc", parameters = new cryptoapiblob { cbdata = 0 } }; algorithmpointer = marshal.allochglobal(marshal.sizeof(algorithm)); marshal.structuretoptr(algorithm, algorithmpointer, false); i pass algorithmpointer method. i error when try pass certcreateselfsigncertificate : an unhandled exception of type 'system.runtime.interopservices.comexception' occurred

thanks kobi resolve problem of checking permutations without repetition given string "abbc". solution (?:(?<a>a)|(?<b>b)|(?<c>c)){4}(?<-a>)(?<-b>){2}(?<-c>) the expression has have 1 "a", 2 "b" , 1 "c" in 4 consecutive characters. now need more complicated, need check expression 2 blocks of permutations: in first 6 positions has find permutations of "abccc" adding each 1 character in 3rd position can of them (a, b or c). in second block has find permutations of "abccc" i don't know if have explained myself well, but: for first 6 positions has have 1 a, 1 b, 3 c , in 3rd position value (a,b or c) no matter order except 3rd position can any for next 5 positions has have 1 a, 1 b , 3 c no matter order. i'm trying explain best way possible. i'm sorry looked copy-paste not. the regex i'm looking "abxccc-abccc" x a, b or c , - separate 2 blocks

this code s2="select notes atotalno =" + combobox1.selecteditem +"" dim cmd oledbcommand=new oledbcommand(s2,myconnection1) cmd.commandtext=s2 textbox1.text=convert.toint32(cmd.executescalar()).tostring() and getting following error:- erorr: data type mismatch in criteria expression apply tostring() on selecteditem , why convert result set integer, if want show in textbox? try this, s2 = "select notes atotalno = "& combobox1.selecteditem.tostring() &"" dim cmd oledbcommand = new oledbcommand(s2, myconnection1) cmd.commandtext = s2 textbox1.text = "" & cmd.executescalar() here resultset concatenated empty string make whole string. if column atotalno of type varchar decorate selecteditem value single quotes. like, s2 = "select notes atotalno = '"& combobox1.selecteditem.tostring() &"'" hope helps thanks.

i have following code fill std::string curl response. struct curl_string { std::string tmpstr; size_t len; }; void init_string(struct curl_string *s) { s->len = 0; } size_t writefunc(void *ptr, size_t size, size_t nmemb, struct curl_string *s) { size_t new_len = s->len + size*nmemb; s->tmpstr.reserve(new_len + 1); memcpy(&s->tmpstr[0] + s->len, ptr, size*nmemb); s->tmpstr[new_len] = '\0'; s->len = new_len; return size*nmemb; } the problem is, though reserve correct length, when try read string, size still 0. i wanted avoid using loop add 1 character @ time. there way still have correct string length in std::string ? your problem std::string::reserve reserves memory characters, doesn't alter length of string. size isn't recalculated when underlying buffer modified, because near-impossible detect in cases. the solution use resize instead of reserve : s->tmpstr.resize(new_len + 1
