• is there a limit on the number of times navigator.geolocation.getCurrentPostion can be called ?

  - by Raja

  Hi all, This is may not be a true programming question but deals with geolocation Api, hence hoping StackOverflow is the right place for this. I'm calling the navigator.geolocation.getCurrentPosition at every 3 seconds interval. After 10-15 tries the responses stop. So i'm wondering is there a limit on the number of calls being made, Or is it because i'm testing it with a desktop and hence instead of giving back the same response each time the API is waiting for a change of location. Anyone has any experiences to share ? Thanks

• Failed to execute stored procedure from the JDBC code using mysql connection

  - by Purushotham

  Hi, I have one database. I executed a stored procedure on it. I wrote some JDBC code to connect to this database. When I am calling this stored procedure from my JDBC code it is throwing SQLException. One interesting thing I found is that I have one user other than root user. This user has all the privileges to this database where the stored procedure is present. When I use the root user I am able to call the stored procedure successfully. But with the other user I am getting SQLexception. I am not able to find why it happens like this. For sure I want this user(other than root) has to call this stored procedure successfully. Thanks in advance.

• How to tell a UITableView to preload all Rows?

  - by Infinite

  Is there a way to tell a UITableView to preload all rows? The tableView is supposed to show several comments (up to 80 comments). So my CommentCell uses a Setter to adapt the cell to a specific comment. -(void)setComment:(Comment *)newComment { if (newComment != comment) { [comment release]; comment = [newComment retain]; /* * set the cells view variables here */ } } This specific setter takes quite a bunch of processing resources and scrolling gets kinda laggy. I am using a comment-specific reuseIdentifier instead of a static cellIdentifier when calling dequeueReusableCellWithIdentifier: in order to assure, that "newComment" equals the old "comment". And in fact this does work great when scrolling over cells which have already been loaded. But when scrolling through the comments for the first time, it still lags like hell. Which leads me to my question: Is there a way to tell the tableview to preload all cells? (which I doubt) or Do I have to implement my own cache instead of relying on "dequeueReusableCellWithIdentifier:"?

• JNI AttachCurrentThread NULLs the jenv

  - by Damg

  Hello all, I'm currently in the process of adding JNI functionality into a legacy delphi app. In a single-threaded environment everything works fine, but as soon as I move into multi-threaded environment, things start to become hairy. My problem is that calling JavaVM^.AttachCurrentThread( JavaVM, @JEnv, nil ); returns 0, but puts the JEnv pointer to nil. I have no idea why jvm.dll should return a NULL pointer. Is there anything I am missing? Thank you in advance -- damg PS: * Environment: WinXP + JDK 1.6 * Using JNI.pas from http://www.pacifier.com/~mmead/jni/delphi/

• EF 4.1 Code First Detaching Entity

  - by Nazaf

  I am trying to add an entity to the DB. Once I have added it, I want to detach it, so I can manipulate the object safely without making any changes to the DB. After calling context.SaveChanges() I do the following to detach the entity: // save context.Stories.Add(story); // attach tags. They already exists in the database foreach(var tag in story.Tags) context.Entry(tag).State = System.Data.EntityState.Unchanged; context.SaveChanges(); context.Entry(story).State = System.Data.EntityState.Detached; However, changing the entity state to DETACHED will remove all related entities associated with the my entity. Is there a way to stop this ? If I don't detach the entity, all my changes are sent to the DB next time I call context.SaveChanges() Thanks!!

• Pattern or recommneded refactoring for method

  - by iKode

  I've written a method that looks like this: public TimeSlotList processTimeSlots (DateTime startDT, DateTime endDT, string bookingType, IList<Booking> normalBookings, GCalBookings GCalBookings, List<DateTime> otherApiBookings) { { ..... common process code ...... while (utcTimeSlotStart < endDT) { if (bookingType == "x") { //process normal bookings using IList<Booking> normalBookings } else if (bookingType == "y") { //process google call bookings using GCalBookings GCalBookings } else if (bookingType == "z" { //process other apibookings using List<DateTime> otherApiBookings } } } So I'm calling this from 3 different places, each time passing a different booking type, and each case passing the bookings I'm interested in processing, as well as 2 empty objects that aren't used for this booking type. I'm not able to get bookings all into the same datatype, which would make this easier and each booking type needs to be processed differently, so I'm not sure how I can improve this. Any ideas?

• How to run a COM .dll on a remote server?

  - by PrgTrdr

  I have a legacy 3rd party COM .dll that is used to provide an Excel-callable interface to a proprietary database product. The .dll runs on the same physical machine as Excel. I have a need to execute the .dll (and the database it is calling) on a remote server while still maintaining simple Excel callability from the client. I'm totally confused by all the different MS technologies that seem to hint there is an easy way to do this. Can someone please point me in the right direction (easier is better)?

• How to execute XSLT 2.0 with ant ?

  - by paulgreg

  I'm trying to run an XSLT transformation from an ant file. I'm using a XSLT 2.0 stylesheet with a saxon 9 parser (supporting XSLT 2.0). The problem is that it seems that ant is always calling an XSLT 1.0 parser. Here's my ant file : <xslt style="stylesheet.xslt" basedir="core/" extension=".xml" destdir="core/" classpath="D:\\DevTools\\saxon\\bin\\saxon9.jar"> </xslt> If I call it directly (without ant), it's working. Any idea ?

• a nicer way to create structs in a loop

  - by sandra

  Hi guys, I haven't coded in C++ in ages. And recently, I'm trying to work on something involving structs. Like this typedef struct{ int x; int y; } Point; Then in a loop, I'm trying to create new structs and put pointers to them them in a list. Point* p; int i, j; while (condition){ // compute values for i and j with some function... p = new Point; p* = {i, j}; //initialize my struct. list.append(p); //append this pointer to my list. } Now, my question is it possible to simplify this? I mean, the pointer variable *p outside of the loop and calling p = new Point inside the loop. Isn't there a better/nicer syntax for this?

• Finding out event that called a CGI script

  - by Acorn

  What I want is to be able to make my CGI script do different things depending on what action initiated the calling of the script. For example, if one button is pressed, a database is cleared. If another button is pressed, a form is submitted and that data is added to the database. Should I be doing something like adding the name of the form/button to the end of the POST data submitted in jQuery and then .poping it off in the script? Or is there some other data that's already sent in the POST that I could get from FieldStorage that would give me the information I need to decide what the script should do when it's called? And what if I wasn't using javascript? Would I have to have a hidden field that gets submitted with the name of the form/button? Or is it best to use a different target script for each button on a page?

• delete data using entity framework

  - by user3474542

  The objective of the method below is to delete the data from the database using entity framework. I am populating the subscriptions entity by passing two parameters and then calling the atttach and remove method of the context class. Bureau entities is the context class. using (BUREAUEntities bureauEntities = new BUREAUEntities()) { var subscription = new SubcriptionRepository().GetSusbcriptionBySubscriptionTypeId(subscriptionTypeId, companyId); bureauEntities.Subscriptions.Attach((DataAccessLayer.DatabaseModel.Subscription)subscription); bureauEntities.Subscriptions.Remove(subscription); bureauEntities.SaveChanges(); } I am getting the following error message at An entity object cannot be referenced by multiple instances of IEntityChangeTracker at line bureauEntities.Subscriptions.Attach((DataAccessLayer.DatabaseModel.Subscription)subscription); Could somebody tell me where am I going wrong ?

• Function calls in virtual machine killing performance

  - by GenTiradentes

  I wrote a virtual machine in C, which has a call table populated by pointers to functions that provide the functionality of the VM's opcodes. When the virtual machine is run, it first interprets a program, creating an array of indexes corresponding to the appropriate function in the call table for the opcode provided. It then loops through the array, calling each function until it reaches the end. Each instruction is extremely small, typically one line. Perfect for inlining. The problem is that the compiler doesn't know when any of the virtual machine's instructions are going to be called, as it's decided at runtime, so it can't inline them. The overhead of function calls and argument passing is killing the performance of my VM. Any ideas on how to get around this?

• How to inline string.h function on linux?

  - by tz1

  I want to optimize some code such that all the functions in string.h will be inlined. I'm on x86_64. I've tried -O3, -minline-all-stringops and when I do "nm a.out" it shows it is calling the glibc version. Checking with gcc -S, I see the calls. What am I missing? There are dozens of #ifdef _SOME_SETTING_ in string.h, and bits/string3.h shows the inline version, but I don't know how to get there. for example: $ cat test.c include main() { char *a, b; strcpy(b,a); } / When compiled with: gcc -minline-all-stringops -O6 -I. -S -o test.S test.c .file "test.c" .text .p2align 4,,15 .globl main .type main, @function main: .LFB12: .cfi_startproc subq $8, %rsp .cfi_def_cfa_offset 16 xorl %esi, %esi xorl %edi, %edi call strcpy addq $8, %rsp .cfi_def_cfa_offset 8 ret .cfi_endproc .LFE12: .size main, .-main .ident "GCC: (GNU) 4.5.1 20100924 (Red Hat 4.5.1-4)" .section .note.GNU-stack,"",@progbits */

• In WPF, how do I update the object that my custom property is bound to?

  - by Timothy Khouri

  I have a custom property that works perfectly, except when it's bound to an object. The reason is that once the following code is executed: base.SetValue(ValueProperty, value); ... then my control is no longer bound. I know this because calling: base.GetBindingExpression(ValueProperty); ... returns the binding object perfectly - UNTIL I call base.SetValue. So my question is, how do I pass the new "value" on to the object that I'm bound to?

• Suggestions for performance improvement surrounding sending email notifications?

  - by jcmoney

  It takes around a couple of seconds for my app to execute the code to send an email right now on a test server with nothing much else running. Not sure if this is typical/expected. I'm also using the php framework Kohana's email helper and not php's mail directly out of convenience if that matters. Is it always just better to schedule a cron job to send emails every 5 min or so? Or should I be able to send emails immediately and I'm just not doing something right? What the script does is insert a row into the db and notifies the relevant group that the row was created. The groups are usually < 20 people so I just do a loop calling Kohana's email helper each time for each member of the group.

• how do I return to the same exact page after posting a form?

  - by William Calleja

  I'm posting data to a page called process.aspx that handles some business logic with the following code: <%@ Page Language="C#" %> <% MyData.process(Request); Response.Redirect("") %> this page I will be calling from a variety of pages. Is there some way of knowing from which page my form was submitted? I was thinking something along the lines of writing: <form id="frmSystem" method="post" action="process.aspx?page=<%= %>"> However I don't know what to write in between the <%= %> to get the current page name. Can anyone help please?

• Ensuring all waiting threads complete

  - by Daniel

  I'm building a system where the progress of calling threads is dependent on the state of two variables. One variable is updated sporadically by an external source (separate from the client threads) and multiple client threads block on a condition of both variables. The system is something like this TypeB waitForB() { // Can be called by many threads. synchronized (B) { while (A <= B) { B.wait(); } A = B; return B; { } void updateB(TypeB newB) { // Called by one thread. synchronized (B) { B.update(newB); B.notifyAll(); // All blocked threads must receive new B. } } I need all the blocked threads to receive the new value of B once it has been updated. But the problem is once a single thread finishes and updates A, the waiting condition becomes true again so some of the other threads become blocked and don't receive the new value of B. Is there a way of ensuring that only the last thread that was blocked on B updates A, or another way of getting this behaviour?

• Placeholder containing dynamic table is empty unless I create table twice

  - by Mike O.

  I am dynamically creating a table that contains a textbox in each cell. The table is put in a placeholder control. Everything displays perfectly. The problem is when I go to retrieve the values entered in the cells. I have the code to generate the table in a separate method called CreateTable(). In order for my program to find a table in the placeholder when I go to save, I have to run CreateTable() in a postback event AND in the PageLoad event. If I call CreateTable() in only one of those places and I try to save, it says the placeholder is empty and, therefore, I cannot save the textbox contents. I've tried calling CreateTable() from InitLoad but that doesn't work because it needs to reference values from three static controls: 1 dropdown, 1 listbox, and 1 calendar control, which I don't believe have had their viewstate rendered yet. Anyone have any ideas? It would sure be nice not to have to double the number of database calls just to make this work.

• How to create and restore a backup from SqlAlchemy?

  - by swilliams

  I'm writing a Pylons app, and am trying to create a simple backup system where every table is serialized and tarred up into a single file for an administrator to download, and use to restore the app should something bad happen. I can serialize my table data just fine using the SqlAlchemy serializer, and I can deserialize it fine as well, but I can't figure out how to commit those changes back to the database. In order to serialize my data I am doing this: from myproject.model.meta import Session from sqlalchemy.ext.serializer import loads, dumps q = Session.query(MyTable) serialized_data = dumps(q.all()) In order to test things out, I go ahead and truncation MyTable, and then attempt to restore using serialized_data: from myproject.model import meta restore_q = loads(serialized_data, meta.metadata, Session) This doesn't seem to do anything... I've tried calling a Session.commit after the fact, individually walking through all the objects in restore_q and adding them, but nothing seems to work. What am I missing? Or is there a better way to do what I'm aiming for? I don't want to shell out and directly touch the database, since SqlAlchemy supports different database engines.

• Inserting asyncronously into Oracle, any benefits?

  - by Karl Trumstedt

  I am using ODP.NET for loading data into Oracle. I am bulking inserts into groups of a 1000 rows each call. Is there any performance benefits in calling my load method asynchronously? So say I want to insert 10000 rows, instead of making 10 calls synchronously I make 10 calls asynchronously. My database is using ASSM right now but otherwise plenty of freelists are used of course. The database server has several cores as well. My initial tests seem to point to a performance increase, but maybe there is something I cannot see? Potential deadlock or contention issues? Of course, there is added complexity in handling transactions and such doing my load this way.

• A $_GET input paramter that's an Array

  I'm trying to pass 3 parameter to a script, where the 3rd parameter $_GET['value3'] is supposed to be an array $_GET['value1'] $_GET['value2'] $_GET['value3'] //an array of items I'm calling the script like this: (notice my syntax for value3, I'm not sure it's correct) http://localhost/test.php?value1=test1&value2=test2&value3=[the, array, values] I then use a foreach to hopefully loop through the third parameter value3 which is the array //process the first input $_GET['value1'] //process the second input $_GET['value2'] //process the third input $_GET['value3'] which is the array foreach($_GET['value3'] as $arrayitem){ echo $arrayitem; } but I get the error Invalid argument supplied for foreach() I'm not sure if my methodology is correct. Can some clarify how you'd go about doing the sort of thing
