i have received corrupt .sdf file client. used sqlceengine.engine method allow me repair point can connect database file , view schema. has recovered of data. although main table have called tablea empty. it created log file seems printing out rows not recover... interesting point "invalid number of columns". 2 years ago schema update pushed out adding 3 new columns. when checked schema on recovered .sdf file missing these 3 columns. assuming schema has corrupted , recovery method trying reinsert rows doesn't match table schema more. find odd cannot recover these 3 columns. can explain more going on log file? i guessing there no way of adding missing columns first , repairing it, rows match possible recovering more data table? many thanks. the log file contains reference tablea, , there 2 types of entry. snippet of log file: block page not found - pwsztable: tablea, idpage: 1465 block page not found - pwsztable: tablea, idpage: 1465 invalid number of

i have mvc-based application basic url-rewriting rule, makes url this: website/controller/action/id . id optional. if user enters invalid action , should error handled in class errorcontroller . all of classes files required in autoloader file, should not require them every time want create object. use spl_autoload_register() autoloading. the problem occurs when try entering url invalid action . example, url website/main/inde (instead of index ) - instance of errorcontroller should created. instead, 2 php errors: warning : require( !core/errorcontroller.php ): failed open stream: no such file or directory in d:\programs\wamp\www\fanfics\v0.0.2!core\autoloader.php on line 5 and fatal error: require(): failed opening required ' !core/errorcontroller.php ' (include_path=' .;c:\php\pear ') in d:\programs\wamp\www\fanfics\v0.0.2!core\autoloader.php on line 5 here visual of files (the exclamation mark before core folder keeping on

sometimes need use several nested monadtrans . example, put maybet inside of exceptt , mimick continue , break in imperative programming: runexceptt . form [1..] $ \ _ -> runmaybet $ ... mzero -- mimics continue lift $ throwe "..." -- mimics break lift . lift $ putstrln "hello!" ... however, above code shows, every time need io inside of "artificial loop", need put ugly lift . lift before it. imagine if have more complicated nestings, , lot of io operations, becomes anonyance. how make code cleaner , more concise? for particular case of io , can use liftio :: monadio m => io -> m a lift io action through arbitrarily deep monad transformer stack: liftio $ putstrln "hello" this expression has type monadio m => m () . transformer stack contains instance of monadio somewhere inside of should have monadio instance itself, why works stack of depth.

i started education software engineering learning basics of java... have create simple text-based airport game , ran little trouble. i tried google , sof search function , found many "solutions" however; none seem fix problem. forgive me "noob" qeustion :p in game have several airports generates random amount of passengers each round, minimum of 100 , maximum of 999. used following code... works , doesnt give me errors still random results below 100. doing wrong? said tried many different ways seems neglect if / if else conditions... int paxgenerator; public int getpaxgenerator() { return this.paxgenerator = (int) (math.random() * 1000); } public void setpaxgenerator(int paxgenerator) { if (paxgenerator<100) { this.paxgenerator = 100; } else if (paxgenerator > 999) { this.paxgenerator = 999; } } edit: return this.paxgenerator = (int) (math.random() * 900) + 100; indeed fix problem, thx @user43219 however, sak

this question has answer here: how set working directory of parent process? 6 answers program: #include<stdio.h> #include<unistd.h> int main() { char s[100]; printf("%s\n",getcwd(s,100)); chdir(".."); printf("%s\n",getcwd(s,100)); return 0; } output: $ ./a.out /home/guest /home $ the above program changes working directory of process. but, doesn't change working directory of current shell. because when program executed in shell, shell follows fork on exec mechanism. so, doesn't affect current shell. is there way change current working directory of shell via these program built-in (cd, echo) command used shell? is there way change current working directory of shell via these program buildin(cd,echo) command used shell

i'm trying run program/function (whichever possible), python program, start , close. example. python script "parent.py" called input, input data passed function/program "child", take around 30 minutes complete. parent.py should closed after calling "child". is there way that? right i'm able start child, parent closed after completion of child. which, want avoid. as understand it, goal start background process in subprocess not have main program wait finish. here example program that: $ cat script.py import subprocess subprocess.popen("sleep 3; echo 'done!';", shell=true) here example of program in operation: $ python script.py $ $ $ done! as can see, shell script continued run after python exited. subprocess has many options , want customize subprocess call needs. in cases, child process lives after parent exits may leave zombie process. instructions on how avoid that, see here . the alterna

i want know how access method sub-class of class when i'm in sub-class of same class... example: class foo { } class bar extends foo { public function something() { //do here } } class soap extends foo { $this->something(); //this method wanna call... } as can see wanna access subclass's method sub class. how do in php? you can directly, if soap subclass of bar : class soap extends bar { public function somefunction() { $this->something(); // work } } if it's not , still have option: obtain instance of bar , call method on it: class soap extends foo { public function somefunction(bar $bar) { $bar->something(); // work } } barring that, there's not else can do. since bar not in soap 's inheritance chain, there no way reference something using $this within of soap 's methods.

i using .net 4 , trying create customcontrol when add customcontrol onto windows form, want have access selectedindexchanged combobox within user control. basically, want when combo box triggers selected indexchanged, run code within windows form. below have far. public partial class customcontrol : usercontrol ... private void uicombobox_selectedindexchanged(object sender, eventargs e) { } what best way want? any appreciated. if uicombobox placed within user control (named customcontrol), can wire handler in constructor follows: uicombobox.selectedindexchanged += uicombobox_selectedindexchanged; if on other hand, uicombobox placed outside customcontrol, you'd need handle event using above technique , manually invoke method in customcontrol. public class myform:form { myform(){ uicombobox.selectedindexchanged += uicombobox_selectedindexchanged; } private void uicombobox_selectedindexchanged(object sender, eventargs e) {

i have sqlite database read dataframe in julia. when values missing, given type sqlite.null, difficult deal with. prefer nas. there easy way conversion? kludgy way follows: using dataframes, sqlite df = dataframe() df[:x1] = [1, sqlite.nulltype(), 3, 4] df[:x2] = ["a", "b", sqlite.nulltype(), "d"] function repnull(x) if isa(x, sqlite.nulltype) return(na) else return(x) end end df[:1] = map(repnull, df[:x1]) df[:2] = map(repnull, df[:x2]) is there more elegant and/or efficient way? i've looked question i'm new julia may have been using wrong terms. the following seems readable , fast. for col in df.columns col[col.==sqlite.null]=na end a curious thing note 'exceptional' behaviour of na under equality. thus, above solution may throw exception if there na s in dataframe (i.e. operation not idempotent).
