  • Child service not writing to event log

    - by Tommy Fisk
    I am having a very simple (but incredibly frustrating) issue with a parent service and the child service. Let's call the parent service "Service A" and the child "Service B". Both services reside on the same box. Using WCF Storm, when I send Service B a message, I see lots of entries in the event viewer for it. However, if I send a message to Service A, which calls Service B, I only see entries from Service A. So for some reason, the child logs are not written when the parent calls it, but if I call it myself, the logs do indeed show up, so I know it's not a problem with the logging or anything like that. Here is what I am using to write to the event log. // in some random static class private static EventLog el = new EventLog(); el.WriteEntry("In " + location + ", " + message); // params passed in Does anyone know why this is happening? And more importantly what I can do about it?

    - by Pushkar
    On my webpage when i press command link its opening a new page perfectly on IE7/Firefox 3/Chrome/Safari 4.0.4 but after this none of the parent page's command buttons are not working ,this happens only in safari.I am using JSF 1.2 mojara. Following is the my command link code: <h:commandLink onclick="submitPrint('selectedAttributes',criteriaGrid,clauseGrid)" action="#{reportBacking.print}" target="_blank"></h:commandLink> I have seen several fourms regarding this problem but they are suggesting the use of new mojara version which solves the some famous javascript problem document.forms Vs document.getElementByID().but my final javascript is fine (its using document.getElementById thing).

  • Python - network buffer handling question...

    - by Patrick Moriarty
    Hi, I want to design a game server in python. The game will mostly just be passing small packets filled with ints, strings, and bytes stuffed into one message. As I'm using a different language to write the game, a normal packet would be sent like so: Writebyte(buffer, 5); // Delimit type of message Writestring(buffer, "Hello"); Sendmessage(buffer, socket); As you can see, it writes the bytes to the buffer, and sends the buffer. Is there any way to read something like this in python? I am aware of the struct module, and I've used it to pack things, but I've never used it to actually read something with mixed types stuck into one message. Thanks for the help.

  • Repeat over files in a File > Open dialog with Applescript

    - by GotNoSugarBaby
    In the below script I use an Application other than Finder to launch an "Open" browser and perform a search in it. I've got the window into the state I want, but whatever I try can't access the list of files to repeat over. If anyone can help by adding the code to repeat over that file list and log out the file path of each file it'd be a huge help. Thanks a lot. tell application "Preview" -- start the app activate -- let it boot up delay 3 -- ensure it still has focus activate end tell tell application "System Events" tell process "Preview" -- spawn "Open" window keystroke "o" using {command down} delay 0.5 -- spawn "Go to" window keystroke "g" using {command down, shift down} delay 0.5 -- expand scope of search to all of this mac keystroke "/" keystroke return delay 0.5 -- spawn search field keystroke "f" using {command down} delay 0.5 -- perform search keystroke ".jpg OR .jpeg" keystroke return end tell end tell

  • JRI Fatal Error on Ubuntu

    - by Peter Jackson
    I have successfully installed JRI and rJava on Windows 7. I am now trying to get it to work on Ubuntu with 64bit OS. I can make rJava calls from within R but getting JRI to work is more difficult. I am running NetBeans 7.1.2 and I have followed various tricks in setting R_HOME and java.library.path to enable all the classes to be loaded. That is, I am past the error messages such as "jri library not found" and "R_HOME not set". From my java code,I can see that R_HOME = /usr/lib64/R. The error message I get now is Fatal error: you must specify '--save', '--no-save' or '--vanilla' This happens when Rengine is first called: Rengine r = new Rengine(args,false,null); This appears to be an error message from R; it seems to be expecting a command line argument. I haven't seen any posting with this error message. Any ideas? Thanks, Peter

  • SQL Querying for Threaded Messages

    - by Harper
    My site has a messaging feature where one user may message another. The messages support threading - a parent message may have any number of children but only one level deep. The messages table looks like this: Messages - Id (PK, Auto-increment int) - UserId (FK, Users.Id) - FromUserId (FK, Users.Id) - ParentMessageId (FK to Messages.Id) - MessageText (varchar 200) I'd like to show messages on a page with each 'parent' message followed by a collapsed view of the children messages. Can I use the GROUP BY clause or similar construct to retrieve parent messages and children messages all in one query? Right now I am retrieving parent messages only, then looping through them and performing another query for each to get all related children messages. I'd like to get messages like this: Parent1 Child1 Child2 Child3 Parent2 Child1 Parent3 Child1 Child2

  • How to add http headers in suds 0.3.6?

    - by Esabe
    Hi everyone, I have an application in python 2.5 which sends data through suds 0.3.6. The problem is that the data contains non-ascii characters, so I need the following header to exist in the soap message: Content-Type="text/html; charset="utf-8" and the header that exists in the SOAP message is just: Content-Type="text/html" I know that it is fixed in suds 0.4, but it requires Python2.6 and I NEED Python2.5 because I use CentOS and it needs that version. So the question is: How could I change or add new HTTP headers to a SOAP message?

  • Need to pass the registry path along with launch parameter ...

    - by velusbits
    I have a situation that demands, passing the registry path as a parameter for application launch, say I have IE as default launcher for http types HKEY_CLASSES_ROOT\http\shell\open\command\ Default = iexplore %1 Any shell launch of a URL would invoke iexplore <<"URL String". My requirement is additionally pass the registry path as parameter, so when a launch happens (note no change in the launch) iexplore <<"URL String" should translate into something like iexplore <<"URL String" "HKEY_CLASSES_ROOT\http\shell\open\command\" How should my registry key HKEY_CLASSES_ROOT\http\shell\open\command\ modified so as to get the extra registry path appended for all shell launches ? Any idea is appreciated, Thanks !

  • Unix - "xargs" - output "in the middle" (not at the end!)

    - by Petike
    Hello, example use of "xargs" application in Unix can be something like this: ls | xargs echo which is the same as (let's say I have "someFile" and "someDir/" in the working dir): echo someFile someDir so "xargs" take its "input" and place it "at the end" of the next command (here at the end of echo). But sometimes I want xargs to place its input somewhere "in the middle" of next command. For example: find . -type f -name "*.cpp" -print | xargs g++ -o outputFile so if I had in the current directory files "a.cpp" "b.cpp" "c.cpp" the output would be the same as with the command: g++ -o outputFile a.cpp b.cpp c.cpp but I want to have something like this: g++ a.cpp b.cpp c.cpp -o outputFile Is there a way to do it? P.S.: I need it in some cases, because e.g.: i586-mingw32msvc-g++ -o outputFile `pkg-config --cflags --libs gtkmm-2.4` a.cpp b.cpp c.cpp doesn't work but this one works fine: i586-mingw32msvc-g++ a.cpp b.cpp c.cpp -o outputFile `pkg-config --cflags --libs gtkmm-2.4` Thanks.

  • Calling software modules (Java, Perl, etc.) from R

    - by harshsinghal
    I've recently started using R for Natural Language Processing tasks and find that a lot of applications are available in Java and Perl (for my purposes). For example: A few perl modules are available to find distance measures between words by querying Wordnet. I am aware of the R Wordnet package, but it does not perform the tasks that these CPAN modules do. Many Java packages for NLP are out there, which I'd like to use from within R. I know of rJava, RSPerl, the simple system command amongst others, but I'd like more examples of how I could make calls to Java and Perl applications from R. Recently I tried capturing console output from a perl script. cat( 'print "Hello World\n";',file="hello.pl" ) system(command="c:\Perl64\bin\perl hello.pl") system(command=paste(Sys.getenv("COMSPEC"),"/c","C:\Perl64\bin\perl hello.pl")) None of the above system commands showed 'Hello World' on the R console. I've used "system" before to run perl scripts to perform tasks without wanting to capture console output. Any hints and redirection to other more extensive sources of information would be highly appreciated. Thank you

  • LINQ to SQL for tables across databases. Or View?

    - by BritishDeveloper
    I have a Message table and a User table. Both are in separate databases. There is a userID in the Message table that is used to join to the User table to find things like userName. How can I create this in LINQ to SQL? I can't seem to do a cross database join. Should I create a View in the database and use that instead? Will that work? What will happen to CRUD against it? E.g. if I delete a message - surely it won't delete the user? I'd imagine it would throw an error. What to do? I can't move the tables into the same database!

  • SQLBindParameter is working fine but SQLExecute gives error in Windows 2008 Server 64bit.

    - by rajugkgp
    Dear All, I am migrating my application from 32bit(Windows 2003 Server) to 64bit (Windows 2008 Server R2).I am getting the following while trying to execute a SQL command Encountered ODBC error -1: S1010, 0, [Microsoft][ODBC Driver Manager] Function sequence error . Basically internal function call is SQLExecute() function call. This works perfectly for Windows 2003 Server 32bit. I tried the command execute at the background from the command prompt and it is working. Any help or suggestion would be very much appreciated. I checked the squence of call.We have two consecutive SQLBindParameter function call and then we call SQLExecute. Is this sequence incorrect in case of 64bit? I also checked the return code given by SQLExecute which is 99. Any pointers or suggestions would be very helpful. The above sequence is working fine with 32bit Windows. Thanks in advance. -R

  • SQL Server db_owner

    - by andrew007
    Hi, in my SQL2008 I have a user which is in the "db_datareader", "db_datawriter" and "db_ddladmin" DB roles, however when he tries to modify a table with SSMS he receives a message saying: You are not logged in as the database owner or system administrator. You might not be able to save changes to tables that you do not own. Of course, I would like to avoid such message, but until now I did find the way... Therefore, I try to modify the user by adding him to the "db_owner" role, and of course I do not have the message above. My question is: Is it possible to keep the user in the "db_owner" role, but deny some actions like alter user or ? I try "alter any user" securable on DB level, but it does not work... THANKS!

  • How to read piped input in Perl?

    - by Jenni
    I am trying to create something in Perl that is basically like the Unix "tee" command. I'm trying to read each line of STDIN, run a substitution on it, and print it. (And eventually, also print it to a file.) This works if I'm using console input, but if I try to pipe input to the command it doesn't do anything. Here's a simple example: print "about to loop\n"; while(<STDIN>) { s/2010/2009/; print; } print "done!\n"; I try to pipe the dir command to it like this: C:\perltestdir | mytee.pl about to loop done! Why is it not seeing the piped input?

  • C errors - Cannot combine with previous 'struct' declaration specifier && Redefinition of 'MyMIDINotifyProc' as different kind of symbol

    - by user1905634
    I'm still new to C but trying to understand it better by working my way through a small MIDI audio unit (in Xcode 4.3.3). I've been searching for an answer to this all day and still don't even understand exactly what the problem is. Here's the code in question: //MyMIDINotifyProc.h #ifndef MIDIInstrumentUnit_CallbackProcs_h #define MIDIInstrumentUnit_CallbackProcs_h void MyMIDINotifyProc (const MIDINotification *message, void *refCon); #endif //MyMIDINotifyProc.c #include <CoreMIDI/CoreMIDI.h> #include "MyMIDINotifyProc.h" void MyMIDINotifyProc (const MIDINotification *message, void *refCon) { //manage notification } In the header definition I get this: ! Cannot combine with previous 'struct' declaration specifier I've made sure the definitions match and tried renaming them and I still get this in my .c file: ! Redefinition of 'MyMIDINotifyProc' as different kind of symbol Which points to the .h definition as the 'Previous definition'. I know that MIDIServices.h in the CoreMIDI framework defines: typedef void (*MIDINotifyProc)(const MIDINotification *message, void *refCon); But I don't understand if/why that would cause an error. I would be grateful if anyone could offer some help.

  • Clojure warn-on-reflection and type hints

    - by Ralph
    In the following code, I am getting a warning on reflection: (ns com.example (:import [org.apache.commons.cli CommandLine Option Options PosixParser])) (def *help-option* "help") (def *host-option* "db-host") (def *options* (doto (Options.) (.addOption "?" *help-option* false "Show this usage information") (.addOption "h" *host-option* true "Name of the database host"))) (let [^CommandLine command-line (.. (PosixParser.) (parse *options* (into-array String args))) db-host (.getOptionValue command-line "h")] ; WARNING HERE ON .getOptionValue ; Do stuff with db-host ) I have a type hint on command-line. Why the warning? I am using Clojure 1.2 on OS X 10.6.6 (Apple VM). I assume that I do not get a warning on (.addOption ...) because the compiler knows that (Options.) is a org.apache.commons.cli.Options).

  • How do I convert a single char in string to an int

    - by Guest
    Keep in mind, if you choose to answer the question, I am a beginner in the field of programming and may need a bit more explanation than others as to how the solutions work. Thank you for your help. My problem is that I am trying to do computations with parts of a string (consisting only of numbers), but I do not know how to convert an individual char to an int. The string is named "message". for (int place = 0; place < message.size(); place++) { if (secondPlace == 0) { cout << (message[place]) * 100 << endl; } } Thank you.
