  • Entity Framework DateTime update extremely slow

    - by Phyxion
    I have this situation currently with Entity Framework: using (TestEntities dataContext = DataContext) { UserSession session = dataContext.UserSessions.FirstOrDefault(userSession => userSession.Id == SessionId); if (session != null) { session.LastAvailableDate = DateTime.Now; dataContext.SaveChanges(); } } This is all working perfect, except for the fact that it is terribly slow compared to what I expect (14 calls per second, tested with 100 iterations). When I update this record manually through this command: dataContext.Database.ExecuteSqlCommand(String.Format("update UserSession set LastAvailableDate = '{0}' where Id = '{1}'", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss.fffffff"), SessionId)); I get 55 calls per second, which is more than fast enough. However, when I don't update the session.LastAvailableDate but I update an integer (e.g. session.UserId) or string with Entity Framework, I get 50 calls per second, which is also more than fast enough. Only the datetime field is terrible slow. The difference of a factor 4 is unacceptable and I was wondering how I can improve this as I don't prefer using direct SQL when I can also use the Entity Framework. I'm using Entity Framework 4.3.1 (also tried 4.1).

  • How can I get an NPC to move randomly in XNA?

    - by Fishwaffles
    I basically want a character to walk in one direction for a while, stop, then go in another random direction. Right now my sprites look but don't move, randomly very quickly in all directions then wait and have another seizure. I will post the code I have so far in case that is useful. class NPC: Mover { int movementTimer = 0; public override Vector2 direction { get { Random rand = new Random(); int randDirection = rand.Next(8); Vector2 inputDirection = Vector2.Zero; if (movementTimer >= 50) { if (randDirection == 4) { inputDirection.X -= 1; movingLeft = true; } else movingLeft = false; if (randDirection == 1) { inputDirection.X += 1; movingRight = true; } else movingRight = false; if (randDirection == 2) { inputDirection.Y -= 1; movingUp = true; } else movingUp = false; if (randDirection == 3) { inputDirection.Y += 25; movingDown = true; } else movingDown = false; if (movementTimer >= 100) { movementTimer = 0; } } return inputDirection * speed; } } public NPC(Texture2D textureImage, Vector2 position, Point frameSize, int collisionOffset, Point currentFrame, Point sheetSize, Vector2 speed) : base(textureImage, position, frameSize, collisionOffset, currentFrame, sheetSize, speed) { } public NPC(Texture2D textureImage, Vector2 position, Point frameSize, int collisionOffset, Point currentFrame, Point sheetSize, Vector2 speed, int millisecondsPerframe) : base(textureImage, position, frameSize, collisionOffset, currentFrame, sheetSize, speed, millisecondsPerframe) { } public override void Update(GameTime gameTime, Rectangle clientBounds) { movementTimer++; position += direction; if (position.X < 0) position.X = 0; if (position.Y < 0) position.Y = 0; if (position.X > clientBounds.Width - frameSize.X) position.X = clientBounds.Width - frameSize.X; if (position.Y > clientBounds.Height - frameSize.Y) position.Y = clientBounds.Height - frameSize.Y; base.Update(gameTime, clientBounds); } }

  • Python Loop for mysql statement

    - by user552974
    Hi, I have a project that i need to compile number of cities in each state and make an insert statement for mysql database. I think the easiest way to do it is via python but since i m a complete noob i would like to reach out all the python gurus here. Here is what the input looks like. Example below is for Florida. cities = ['Boca Raton', 'Boynton Beach', 'Bradenton', 'Cape Coral', 'Deltona'] and this what the output should be. INSERT INTO `oc_locations` (`idLocation`, `name`, `idLocationParent`, `friendlyName`) VALUES (1, 'Florida', 0, 'Florida'), (2, 'Boca Raton', 1, 'Boca Raton'), (3, 'Boynton Beach', 1, 'Boynton Beach'), (4, 'Bradenton', 1, 'Bradenton'), (5, 'Cape Coral', 1, 'Cape Coral'), (6, 'Deltona', 1, 'Deltona'), If you look at carefully the "idLocationParent" for "Florida" value is "0" so which means it is a top level value. This will be done for 50 states so ability to plug the state name into the mysql statement would be icing on the cake if there is a easy way to do it. Also alphabetical order and auto increment for the idLocation would be great. Here is an example of what i m trying to achieve concatenation is the part i need to figure out. for city in cities: print (1, 'city', 0, 'city'), city

  • How do I resize an iframe with dynamic content?

    - by Middletone
    I'm populating an iframe with some contents that are injected into it but I'm unable to size it correctly. I've tried a variety of methods but here is the most recent code. After populating the iframe with an html based mail message it doesn't seem to register the scroll height. <iframe scrolling="no" width="100%" onload="javascript:(LoadIFrame(this));" > HTML content goes here. Make sure it's long enough to need to scroll before testing. </iframe> <script type="text/javascript"> function LoadIFrame(iframe) { $("iframe").each(function() { $(this).load(function() { var doc = this.document; if (this.contentDocument) { doc = this.contentDocument; } else if (this.contentWindow) { doc = this.contentWindow.document; } else if (this.document) { doc = this.document; } this.height = (doc.body.scrollHeight + 50) + 'px'; this.onload = ''; }); txt = $(this).text(); var doc = this.document; if (this.contentDocument) { doc = this.contentDocument; } else if (this.contentWindow) { doc = this.contentWindow.document; } else if (this.document) { doc = this.document; } doc.open(); doc.writeln(txt); doc.close(); }); } </script>

  • Check for child duplicates

    - by ebb
    My console app will loop through each User to get their Websites, so that it can take new screenshots of them. However, to prevent taking screenshot of the same website twice I have to check whether there already has been taken screenshot of the website, while looping through another users websites. My current solution is: Database: User |--> ID: 1 |--> FirstName: Joe |--> ID: 2 |--> FirstName: Stranger Websites |--> ID: 1 |--> UserID: 1 |--> URL: http://site.com |--> ID: 2 |--> UserID: 2 |--> URL: http://site.com Console app: static void RenewWebsiteThumbNails() { Console.WriteLine("Starting renewal process..."); using (_repository) { var websitesUpdated = new List<string>(); foreach (var user in _repository.GetAll()) { foreach (var website in user.Websites.Where(website => !websitesUpdated.Contains(website.URL))) { _repository.TakeScreenDumpAndSave(website.URL); websitesUpdated.Add(website.URL); Console.WriteLine(new string('-', 50)); Console.WriteLine("{0} has successfully been renewed", website.URL); } } } } However, it seems wrong to declare a List for such a scenario, just to check whether a specific URL already has been added... any suggestions for an alternative way?

  • Why would paperclip not assign an ID to my uploaded photos?

    - by Trip
    I just deployed to a cluster server, and my delayed_jobs recipe was overwritten in the process. I solved that, delayed_jobs is up and running but can't find the ID of images that are uploaded.

Anyone know where I could poke and pry from here? UPDATE: I created a clone application on a single server. And there are no problems. The images on the cluster do show up (occassionally). If I keep clicking on the folders that lead to photos, it will 50% of the time return a 404 with it not being able to find the photo, and the other half it will present the photo. So the problem has got to be with the server interaction between the ActiveRecord through multiple servers.

  • error while updating a database in ASP.NET

    - by Viredae
    I am having trouble updating an SQL database, the problem is not that it doesn't update at all, but that particular parameters are being updated while the others are not. here is the code for updating the parameters: string EditRequest = "UPDATE Requests SET Description = @Desc, BJustif = @Justif, Priority = @Priority, Requested_System = @Requested, Request_Status = @Stat WHERE"; EditRequest += " Req_ID=@ID"; SqlConnection Submit_conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["DBConn"].ConnectionString); SqlCommand Submit_comm = new SqlCommand(EditRequest, Submit_conn); Submit_comm.Parameters.AddWithValue("@ID", Request.QueryString["reqid"]); Submit_comm.Parameters.AddWithValue("@Desc", DescBox.Text); Submit_comm.Parameters.AddWithValue("@Justif", JustifBox.Text); Submit_comm.Parameters.AddWithValue("@Priority", PriorityList.SelectedValue); Submit_comm.Parameters.AddWithValue("@Requested", RelatedBox.Text); Submit_comm.Parameters.AddWithValue("@Stat", 1); Submit_conn.Open(); Submit_comm.ExecuteNonQuery(); Submit_comm.Dispose(); Submit_comm = null; Submit_conn.Close(); get_Description(); Page.ClientScript.RegisterStartupScript(this.GetType(), "Refresh", "ReloadPage();", true); this function is called by a button on a pop-up form which shows the parameters content that is being changed in a text box which is also used to submit the changes back to the database, but when I press submit, the parameters which are displayed on the form don't change, I can't find any problem wit the code, even though I've compared it to similar code which is working fine. In case you need to, here is one of the text boxes I'm using to display and edit the content: <asp:TextBox ID="JustifBox" TextMode="MultiLine" runat="server" Width="250" Height="50"></asp:TextBox> What exactly is wrong with the code?

  • Accessing the value of an input element with XPath in an XSLT

    - by asymmetric
    Hi! I'm developing a web app that has a button that triggers an XSLT transformation of the document DOM, with a stylesheet fetched via AJAX. Here's a portion of the HTML: <html> <head> <title>Static Javascript-based XMR Form Creator</title> </head> <body> <h1 id="title">Static Javascript-based XMR Form Creator</h1> <div class="opt_block" id="main_opts"> Form name <input type="text" id="form_name" /> Form cols <input type="text" id="form_cols" size="3" maxlength="3" /> </div> <button id="generate">Generate source</button> <textarea rows="20" cols="50" id="xmr_source" ></textarea> </body> Inside the stylesheet, I want to access the value attribute of the first input field, the one with id form_name. The XSLT looks like this: <xsl:template match="/html/body/div[@id = 'main_opts']" > <form> <xsl:attribute name="fname"> <xsl:value-of select="input[@id = 'form_name']/@value" /> </xsl:attribute> </form> </xsl:template> The problem is that the XPath that should do the work: <xsl:value-of select="input[@id = 'form_name']/@value" /> returns nothing. Can anyone help?

  • pyOpenSSL and the WantReadError

    - by directedition
    I have a socket server that I am trying to move over to SSL on python 2.5, but I've run into a snag with pyOpenSSL. I can't find any good tutorials on using it, so I'm operating largely on guesses. Here is how my server sets up the socket: ctx = SSL.Context(SSL.SSLv23_METHOD) ctx.use_privatekey_file ("mykey.pem") ctx.use_certificate_file("mycert.pem") sock = SSL.Connection(ctx, socket.socket(socket.AF_INET, socket.SOCK_STREAM)) sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) addr = ('', int(8081)) sock.bind(addr) sock.listen(5) Here is how it accepts clients: sock.setblocking(0) while True: if len(select([sock], [], [], 0.25)[0]): client_sock, client_addr = sock.accept() client = ClientGen(client_sock) And here is how it sends/receives from the connected sockets: while True: (r, w, e) = select.select([sock], [sock], [], 0.25) if len(r): bytes = sock.recv(1024) if len(w): n_bytes = sock.send(self.message) It's compacted, but you get the general idea. The problem is, once the send/receive loop starts, it dies right away, before anything has been sent or received (that I can see anyway): Traceback (most recent call last): File "ClientGen.py", line 50, in networkLoop n_bytes = sock.send(self.message WantReadError The manual's description of the 'WantReadError' is very vague, saying it can come from just about anywhere. What am I doing wrong?

  • Findbugs and comparing

    - by Rob Goodwin
    I recently started using the findbugs static analysis tool in a java build I was doing. The first report came back with loads of High Priority warnings. Being the obsessive type of person, I was ready to go knock them all out. However, I must be missing something. I get most of the warnings when comparing things. Such as the following code: public void setSpacesPerLevel(int value) { if( value >= 0) { ... produces a high priority warning at the if statement that reads. File: Indenter.java, Line: 60, Type: BIT_AND_ZZ, Priority: High, Category: CORRECTNESS Check to see if ((...) & 0) == 0 in sample.Indenter.setSpacesPerLevel(int) I am comparing an int to an int, seems like a common thing. I get quite a few of that type of error with similar simple comparisons. I have alot of other high priority warnings on what appears to be simple code blocks. Am I missing something here? I realize that static analysis can produce false positives, but the errors I am seeing seem too trivial of a case to be a false positive. This one has me scratching my head as well. for(int spaces = 0;spaces < spacesPerLevel;spaces++){... Which gives the following findbugs warning: File: Indenter.java, Line: 160, Type: IL_INFINITE_LOOP, Priority: High, Category: CORRECTNESS There is an apparent infinite loop in sample.Indenter.indent() This loop doesn't seem to have a way to terminate (other than by perhaps throwing an exception). Any ideas? So basically I have a handful of files and 50-60 high priority warnings similar to the ones above. I am using findbugs 1.3.9 and calling it from the findbugs ant task

  • Android: Speeding up display of (html-formatted) text

    - by prepbgg
    My app uses a StringBuilder to assemble paragraphs of text which are then displayed in a TextView within a ScrollView. The displaytext.xml layout file is: <?xml version="1.0" encoding="utf-8"?> <LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#FFFFFF" xmlns:android="http://schemas.android.com/apk/res/android"> <ScrollView android:id="@+id/ScrollView01" android:layout_width="fill_parent" android:layout_height="wrap_content" > <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/display_text" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textColor="#000000" > </TextView> </ScrollView> </LinearLayout> and the code that displays the StringBuilder object sbText is setContentView(R.layout.displaytext); TextView tv = (TextView)findViewById(R.id.display_text); tv.setText(Html.fromHtml(sbText.toString())); This works OK, except that it gets very slow as the amount of text grows. For example, to display 50 paragraphs totalling about 50KB of text takes over 5 seconds just to execute those three lines of code. Can anyone suggest how I can speed this up, please?

  • Somewhat lost with jquery + php + json

    - by Luis Armando
    I am starting to use the jquery $.ajax() but I can't get back what I want to...I send this: $(function(){ $.ajax({ url: "graph_data.php", type: "POST", data: "casi=56&nada=48&nuevo=98&perfecto=100&vales=50&apenas=70&yeah=60", dataType: "json", error: function (xhr, desc, exceptionobj) { document.writeln("El error de XMLHTTPRequest dice: " + xhr.responseText); }, success: function (json) { if (json.error) { alert(json.error); return; } var output = ""; for (p in json) { output += p + " : " + json[p] + "\n"; } document.writeln("Results: \n\n" + output); } }); }); and my php is: <?php $data = $_POST['data']; function array2json($data){ $json = $data; return json_encode($json); } ?> and when I execute this I come out with: Results: just like that I used to have in the php a echo array2json statement but it just gave back gibberish...I really don't know what am I doing wrong and I've googled for about 3 hours just getting basically the same stuff.

  • Help with SQL query (Calculate a ratio between two entitiess)

    - by Mestika
    Hi, I’m going to calculate a ratio between two entities but are having some trouble with the query. The principal is the same to, say a forum, where you say: A user gets points for every new thread. Then, calculate the ratio of points for the number of threads. Example: User A has 300 points. User A has started 6 thread. The point ratio is: 50:6 My schemas look as following: student(studentid, name, class, major) course(courseid, coursename, department) courseoffering(courseid, semester, year, instructor) faculty(name, office, salary) gradereport(studentid, courseid, semester, year, grade) The relations is a following: Faculity(name) = courseoffering(instructor) Student(studentid) = gradereport (studentid) Courseoffering(courseid) = course(courseid) Gradereport(courseid) = courseoffering(courseid) I have this query to select the faculty names there is teaching one or more students: SELECT COUNT(faculty.name) FROM faculty, courseoffering, gradereport, student WHERE faculty.name = courseoffering.instructor AND courseoffering.courseid = gradereport.courseid AND gradereport.studentid = student.studentid My problem is to find the ratio between the faculty members salary in regarding to the number of students they are teaching. Say, a teacher get 10.000 in salary and teaches 5 students, then his ratio should be 1:5. I hope that someone has an answer to my problem and understand what I'm having trouble with. Thanks Mestika

  • Magento products will not show in category

    - by Aaron
    I've recently been tasked with the build and deployment of a large Ecommerce site. In the past we've had to use the clients legacy X-cart installation for redevelopment (too far integrated with their existing work flow). We'd heard good things about Magento, so I've set up a test install to get to grips with it. After a couple of initial issues, there is a live development site which displays categories on the default theme. The problem we've hit now is that products don't display..! After a lot more in-depth research into this, all I've been able to discover is that quite a number of developers endorse using other solutions entirely, with the other 50% saying after the steep learning curve the platform is as wonderful as we'd initially been led to believe. Now, my test category is showing, so I know this is configured properly. I've set up three test products and associated them with this (all done following the Magento user guide), checked double checked and thrice checked the products are enabled and visible individually, yet still the front end says the category has no products in it. I've cleared the cache repeatedly, reset everything possible many times in index management - no products show up. I have to make a call tomorrow morning on whether we're going ahead with Magento. If I can't even get it to show products I'm going to have to go with something with a more established track record and more community support available. Can anybody advise what could possibly be wrong here?

  • MySQL Can Connect Remotely but not Locally

    - by A Wizard Did It
    This is a weird problem and I'm not sure what's going on. I installed MySQL on a linux box I have running Ubuntu 10.04 LTS. I can access mysql via SSH mysql -p and perform all my commands that way. I added a user, and I can use AddedUser to connect remotely from my machine, but not from the local machine. It makes no sense to me... SELECT host, user FROM mysql.user Yields: +-----------+------------------+ | host | user | +-----------+------------------+ | % | AddedUser | | 127.0.0.1 | root | | li241-255 | root | | localhost | debian-sys-maint | | localhost | root | +-----------+------------------+ Problem is I'm developing on this machine using Node.js, and I can't connect locally from the server using the same username. I've tried FLUSH PRIVILEGES but that seems to have no effect. I know it's not Node.js because I'm using the same code on another database and it's working in that environment. Edit This is the error node is giving me. node.js:50 throw e; // process.nextTick error, or 'error' event on first tick ^ Error: ECONNREFUSED, Connection refused at Stream._onConnect (net.js:687:18) at IOWatcher.onWritable [as callback] (net.js:284:12) Edit 2 I have the right port & server as best I can tell.

    I have the following JavaScript function on a page: function setFields(){ var menu = document.getElementById('EditLocation'); var itemDataArray = menu[menu.selectedIndex].value.split('|'); form.LocationShortName.value = itemDataArray[0]; form.LocationLongName.value = itemDataArray[1]; form.Phone.value = itemDataArray[2]; form.Address1.value = itemDataArray[3]; form.CityStateZip.value = itemDataArray[4]; form.MapLink.value = itemDataArray[5]; } Down on the Form, I have the following: <select class="input2" name="EditLocation" id="EditLocation" onchange = "setFields();"> <option value="-Add New-"<?php if($editlocation=='-Add New-'){echo(' selected="selected"');} ?>>-Add New-</option> <?php require_once('connection.php'); $connection = mysql_connect($hostname,$username,$password) or die (mysql_errno().": ".mysql_error()."<BR />"); mysql_select_db($database); $sql = "SELECT * FROM directions ORDER BY dirshortname"; $query = mysql_query($sql); while ($row = mysql_fetch_array($query)) { echo('<option value="'.stripslashes($row['dirshortname']).'|'.stripslashes($row['dirlongname']).'|'.stripslashes($row['dirphone']).'|'.stripslashes($row['dirstreet']).'|'.stripslashes($row['dircsz']).'|'.stripslashes($row['dirmaplink']).'"'); if ($editlocation==stripslashes($row['dirshortname'])) { echo(' selected="selected"'); } echo('>'.stripslashes($row['dirshortname']).'</option>'); } ?> In essence, the PHP is supposed to pack the data elements pulled from MySQL into the OPTION VALUE portion of the SELECT box. Once the user selects a record, the JavaScript pulls the packed data apart and populates the other data elements on the FORM. It all works wonderfully in IE, but in FF the fields do not populate with data. The form is somewhat long, but I'll include it anyway for the sake of completeness. <form action="admin-dirs.php" method="post" enctype="multipart/form-data" style="margin:0px; padding:0px " id="form"> <table width="587" border="0" cellspacing="0" cellpadding="0"> <tr> <td width="60">&nbsp;</td> <td width="185">Select Location to Edit: </td> <td width="342"><select class="input2" name="EditLocation" id="EditLocation" onchange = "setFields();"> <option value="-Add New-"<?php if($editlocation=='-Add New-'){echo(' selected="selected"');} ?>>-Add New-</option> <?php require_once('connection.php'); $connection = mysql_connect($hostname,$username,$password) or die (mysql_errno().": ".mysql_error()."<BR />"); mysql_select_db($database); $sql = "SELECT * FROM directions ORDER BY dirshortname"; $query = mysql_query($sql); while ($row = mysql_fetch_array($query)) { echo('<option value="'.stripslashes($row['dirshortname']).'|'.stripslashes($row['dirlongname']).'|'.stripslashes($row['dirphone']).'|'.stripslashes($row['dirstreet']).'|'.stripslashes($row['dircsz']).'|'.stripslashes($row['dirmaplink']).'"'); if ($editlocation==stripslashes($row['dirshortname'])) { echo(' selected="selected"'); } echo('>'.stripslashes($row['dirshortname']).'</option>'); } ?> </select></td> </tr> <tr> <td width="60">&nbsp;</td> <td colspan="2"><span class="main" style=" padding-left:12px; padding-right:12px; padding-top:6px"><br /> (Note: Leaving the Long Name blank will duplicate the Short Name.)</span></td> </tr> <?php if(!$errlocationshortname=='' ){echo(' <tr> <td width="60">&nbsp;</td> <td width="185">&nbsp;</td> <td width="342"><span class="redtxterror">'.$errlocationshortname.'</span></td> </tr>');} ?> <tr> <td>&nbsp;</td> <td>Location Short Name: <span class="red_star">*</span> </td> <td><input name="LocationShortName" id="LocationShortName" type="text" class="input2<?php if(!$errlocationshortname==''){echo('r');} ?>" value="<?php echo($locationshortname); ?>" maxlength="50"></td> </tr> <?php if(!$errlocationlongname=='' ){echo(' <tr> <td width="60">&nbsp;</td> <td width="185">&nbsp;</td> <td width="342"><span class="redtxterror">'.$errlocationlongname.'</span></td> </tr>');} ?> <tr> <td>&nbsp;</td> <td>Location Long Name: <span class="red_star">*</span> </td> <td><input name="LocationLongName" id="LocationLongName" type="text" class="input2<?php if(!$errlocationlongname==''){echo('r');} ?>" value="<?php echo($locationlongname); ?>" maxlength="50"></td> </tr> <?php if(!$erraddress=='' ){echo(' <tr> <td width="60">&nbsp;</td> <td width="185">&nbsp;</td> <td width="342"><span class="redtxterror">'.$erraddress.'</span></td> </tr>');} ?> <tr> <td>&nbsp;</td> <td>Street Address: <span class="red_star">*</span> </td> <td><input name="Address1" id="Address1" type="text" class="input2<?php if(!$erraddress==''){echo('r');} ?>" value="<?php echo($address); ?>"></td> </tr> <?php if(!$errcsz=='' ){echo(' <tr> <td width="60">&nbsp;</td> <td width="185">&nbsp;</td> <td width="342"><span class="redtxterror">'.$errcsz.'</span></td> </tr>');} ?> <tr> <td>&nbsp;</td> <td>City, State, Zip: <span class="red_star">*</span> </td> <td><input name="CityStateZip" id="CityStateZip" type="text" class="input2<?php if(!$errcsz==''){echo('r');} ?>" value="<?php echo($csz); ?>"></td> </tr> <?php if(!$errphone=='' ){echo(' <tr> <td width="60">&nbsp;</td> <td width="185">&nbsp;</td> <td width="342"><span class="redtxterror">'.$errphone.'</span></td> </tr>');} ?> <tr> <td>&nbsp;</td> <td>Location Phone Number: <span class="red_star">*</span> </td> <td><input name="Phone" id="Phone" type="text" class="input2<?php if(!$errphone==''){echo('r');} ?>" value="<?php echo($phone); ?>" maxlength="20"></td> </tr> <?php if(!$errmaplink=='' ){echo(' <tr> <td width="60">&nbsp;</td> <td width="185">&nbsp;</td> <td width="342"><span class="redtxterror">'.$errmaplink.'</span></td> </tr>');} ?> <tr> <td>&nbsp;</td> <td>Paste Link to Map: <span class="red_star">*</span> </td> <td><input name="MapLink" id="MapLink" type="text" class="input2<?php if(!$errmaplink==''){echo('r');} ?>" value="<?php echo($maplink); ?>" maxlength="125"></td> </tr> <tr> <td>&nbsp;</td> <td>&nbsp;</td> <td><div align="right" style="padding-right:25px"> <input type="hidden" id="action" name="action" value="submitform" /> <input type="submit" id="savenew" name="savenew" value="Save & New" /> <input type="submit" id="submit" name="submit" value="Save & Close" /> <?php if(!isset($_POST['action'])) {?> <input type="reset" id="reset" name="reset" value="Reset" /> <?php } ?> </div></td> </tr><tr> <td>&nbsp;</td> <td>&nbsp;</td> <td class="main_d"><div align="right" style="padding-right:25px">Your IP Address is Logged as: <?php echo($ip); ?></div></td> </tr> </table> </form>

  • Objective-C ref count and autorelease

    - by turbovince
    Hey guys, suppose the following code: int main (int argc, const char * argv[]) { //[...] Rectangle* myRect = [[Rectangle alloc] init]; Vector2* newOrigin = [[[Vector2 alloc] init] autorelease]; // ref count 1 [newOrigin setX: 50.0f]; [myRect setOrigin: newOrigin]; // ref count 2 [myRect.origin setXY: 25.0f :100.0f]; // ref count goes to 3... why ? [myRect release]; [pool drain]; return 0; } Rectangle's origin is declared as a (retain) synthesized property. Just wondering 2 things: Why does ref count goes to 3 when using the getter accessor of Rectangle's origin? Am I doing something wrong ? With a ref count of 3, I don't understand how this snippet of code cannot leak. Calling release on myRect will make it go down to 2 since I call release on the origin in dealloc(). But then, when does autorelease take effect? Thanks!

  • problem finding a header with a c++ makefile

    - by Max
    Hi. I've started working with my first makefile. I'm writing a roguelike in C++ using the libtcod library, and have the following hello world program to test if my environment's up and running: #include "libtcod.hpp" int main() { TCODConsole::initRoot(80, 50, "PartyHack"); TCODConsole::root->printCenter(40, 25, TCOD_BKGND_NONE, "Hello World"); TCODConsole::flush(); TCODConsole::waitForKeypress(true); } My project directory structure looks like this: /CppPartyHack ----/libtcod-1.5.1 # this is the libtcod root folder --------/include ------------libtcod.hpp ----/PartyHack --------makefile --------partyhack.cpp # the above code (while we're here, how do I do proper indentation? Using those dashes is silly.) and here's my makefile: SRCDIR = . INCDIR = ../libtcod-1.5.1/include CFLAGS = $(FLAGS) -I$(INCDIR) -I$(SRCDIR) -Wall CC = gcc CPP = g++ .SUFFIXES: .o .h .c .hpp .cpp $(TEMP)/%.o : $(SRCDIR)/%.cpp $(CPP) $(CFLAGS) -o $@ -c $< $(TEMP)/%.o : $(SRCDIR)/%.c $(CC) $(CFLAGS) -o $@ -c $< CPP_OBJS = $(TEMP)partyhack.o all : partyhack partyhack : $(CPP_OBJS) $(CPP) $(CPP_OBJS) -o $@ -L../libtcod-1.5.1 -ltcod -ltcod++ -Wl,-rpath,. clean : \rm -f $(CPP_OBJS) partyhack I'm using Ubuntu, and my terminal gives me the following errors: max@max-desktop:~/Desktop/Development/CppPartyhack/PartyHack$ make g++ -c -o partyhack.o partyhack.cpp partyhack.cpp:1:23: error: libtcod.hpp: No such file or directory partyhack.cpp: In function ‘int main()’: partyhack.cpp:5: error: ‘TCODConsole’ has not been declared partyhack.cpp:6: error: ‘TCODConsole’ has not been declared partyhack.cpp:6: error: ‘TCOD_BKGND_NONE’ was not declared in this scope partyhack.cpp:7: error: ‘TCODConsole’ has not been declared partyhack.cpp:8: error: ‘TCODConsole’ has not been declared make: * [partyhack.o] Error 1 So obviously, the makefile can't find libtcod.hpp. I've double checked and I'm sure the relative path to libtcod.hpp in INCDIR is correct, but as I'm just starting out with makefiles, I'm uncertain what else could be wrong. My makefile is based off a template that the libtcod designers provided along with the library itself, and while I've looked at a few online makefile tutorials, the code in this makefile is a good bit more complicated than any of the examples the tutorials showed, so I'm assuming I screwed up something basic in the conversion. Thanks for any help.

  • PostgreSQL storing paths for reference in scripts

    - by Brian D.
    I'm trying to find the appropriate place to store a system path in PostgreSQL. What I'm trying to do is load values into a table using the COPY command. However, since I will be referring to the same file path regularly I want to store that path in one place. I've tried creating a function to return the appropriate path, but I get a syntax error when I call the function in the COPY command. I'm not sure if this is the right way to go about it, but I'll post my code anyway. COPY command: COPY employee_scheduler.countries (code, name) FROM get_csv_path('countries.csv') WITH CSV; Function Definition: CREATE OR REPLACE FUNCTION employee_scheduler.get_csv_path(IN file_name VARCHAR(50)) RETURNS VARCHAR(250) AS $$ DECLARE path VARCHAR(200) := E'C:\\Brian\\Work\\employee_scheduler\\database\\csv\\'; file_path VARCHAR(250) := ''; BEGIN file_path := path || file_name; RETURN file_path; END; $$ LANGUAGE plpgsql; If anyone has a different idea on how to accomplish this I'm open to suggestions. Thanks for any help!

  • Creating and appending a big DOM with javascript - most optimized way?

    - by fenderplayer
    I use the following code to append a big dom on a mobile browser (webkit): 1. while(someIndex--) // someIndex ranges from 10 to possibly 1000 2. { 3. var html01 = ['<div class="test">', someVal,'</div>', 4. '<div><p>', someTxt.txt1, someTxt.txt2, '</p></div>', 5. // lots of html snippets interspersed with variables 6. // on average ~40 to 50 elements in this array 7. ].join(''); 8. var fragment = document.createDocumentFragment(), 9. div = fragment.appendChild(document.createElement('div')); 10. div.appendChild(jQuery(html01)[0]); 11. jQuery('#screen1').append(fragment); 12. } //end while loop 13. // similarly i create 'html02' till 'html15' to append in other screen divs Is there a better or faster way to do the above? Do you see any problems with the code? I am a little worried about line 10 where i wrap in jquery and then take it out.

  • Load Testing Java Web Application - find TPS / Avg transaction response time

    - by Steve
    I would like to build my own load testing tool in Java with the goal of being able to load test a web application I am building throughout the development cycle. The web application will be receiving server to server HTTP Post requests and I would like to find its starting transaction per second (TPS) capacity along with the avgerage response time. The Post request and response messages will be in XML (I dont' think that's really applicable though :) ). I have written a very simple Java app to send transactions and count how many transactions it was able to send in one second (1000 ms) however I don't think this is the best way to load test. Really what I want is to send any number of transactions at exactly the same time - i.e. 10, 50, 100 etc. Any help would be appreciated! Oh and here is my current test app code: Thread[] t = new Thread[1]; for (int a = 0; a < t.length; a++) { t[a] = new Thread(new MessageLoop()); } startTime = System.currentTimeMillis(); System.out.println(startTime); for (int a = 0; a < t.length; a++) { t[a].start(); } while ((System.currentTimeMillis() - startTime) < 1000 ) { } if ((System.currentTimeMillis() - startTime) > 1000 ) { for (int a = 0; a < t.length; a++) { t[a].interrupt(); } } long endTime = System.currentTimeMillis(); System.out.println(endTime); System.out.println("Total time: " + (endTime - startTime)); System.out.println("Total transactions: " + count); private static class MessageLoop implements Runnable { public void run() { try { //Test Number of transactions while ((System.currentTimeMillis() - startTime) < 1000 ) { // SEND TRANSACTION HERE count++; } } catch (Exception e) { } } }

  • Data historian queries

    - by Scott Dennis
    Hi, I have a table that contains data for electric motors the format is: DATE(DateTime) | TagName(VarChar(50) | Val(Float) | 2009-11-03 17:44:13.000 | Motor_1 | 123.45 2009-11-04 17:44:13.000 | Motor_1 | 124.45 2009-11-05 17:44:13.000 | Motor_1 | 125.45 2009-11-03 17:44:13.000 | Motor_2 | 223.45 2009-11-04 17:44:13.000 | Motor_2 | 224.45 Data for each motor is inserted daily, so there would be 31 Motor_1s and 31 Motor_2s etc. We do this so we can trend it on our control system displays. I am using views to extract last months max val and last months min val. Same for this months data. Then I join the two and calculate the difference to get the actual run hours for that month. The "Val" is a nonresetable Accumulation from a PLC(Controller). This is my query for Last months Max Value: SELECT TagName, Val AS Hours FROM dbo.All_Data_From_Last_Mon AS cur WHERE (NOT EXISTS (SELECT TagName, Val FROM dbo.All_Data_From_Last_Mon AS high WHERE (TagName = cur.TagName) AND (Val > cur.Val))) This is my query for Last months Max Value: SELECT TagName, Val AS Hours FROM dbo.All_Data_From_Last_Mon AS cur WHERE (NOT EXISTS (SELECT TagName, Val FROM dbo.All_Data_From_Last_Mon AS high WHERE (TagName = cur.TagName) AND (Val < cur.Val))) This is the query that calculates the difference and runs a bit slow: SELECT dbo.Motors_Last_Mon_Max.TagName, STR(dbo.Motors_Last_Mon_Max.Hours - dbo.Motors_Last_Mon_Min.Hours, 12, 2) AS Hours FROM dbo.Motors_Last_Mon_Min RIGHT OUTER JOIN dbo.Motors_Last_Mon_Max ON dbo.Motors_Last_Mon_Min.TagName = dbo.Motors_Last_Mon_Max.TagName I know there is a better way. Ultimately I just need last months total and this months total. Any help would be appreciated. Thanks in advance

  • Best way to migrate export/import from SQL Server to oracle

    - by matao
    Hi guys! I'm faced with needing access for reporting to some data that lives in Oracle and other data that lives in a SQL Server 2000 database. For various reasons these live on different sides of a firewall. Now we're looking at doing an export/import from sql server to oracle and I'd like some advice on the best way to go about it... The procedure will need to be fully automated and run nightly, so that excludes using the SQL developer tools. I also can't make a live link between databases from our (oracle) side as the firewall is in the way. The data needs to be transformed in the process from a star schema to a de-normalised table ready for reporting. What I'm thinking about is writing a monster query for SQL Server (which I mostly have already) that will denormalise and read out the data from SQL Server into a flat file using the sql server equivalent of sqlplus as a scheduled task, dump into a Well Known Location, then on the oracle side have a cron job that copies down the file and loads it with sql loader and rebuilds indexes etc. This is all doable, but very manual. Is there one or a combination of FOSS or standard oracle/SQL Server tools that could automate this for me? the Irreducible complexity is the query on one side and building indexes on the other, but I would love to not have to write the CSV dumping detail or the SQL loader script, just say dump this view out to CSV on one side, and on the other truncate and insert into this table from CSV and not worry about mapping column names and all other arcane sqlldr voodoo... best practices? thoughts? comments? edit: I have about 50+ columns all of varying types and lengths in my dataset, which is why I'd prefer to not have to write out how to generate and map each single column...

  • ASP.NET Web Application: use 1 or multiple virtual directories

    - by tster
    I am working on a (largish) internal web application which has multiple modules (security, execution, features, reports, etc.). All the pages in the app share navigation, CSS, JS, controls, etc. I want to make a single "Web Application" project, which includes all the pages for the app, then references various projects which will have the database and business logic in them. However, some of the people on the project want to have separate projects for the pages of each module. To make this more clear, this is what I'm advocating to be the projects. /WebInterface* /SecurityLib /ExecutionLib etc... And here is what they are advocating: /SecurityInterface* /SecutiryLib /ExecutionInterface* /ExecutionLib etc... *project will be published to a virtual directory of IIS Basically What I'm looking for is the advantages of both approaches. Here is what I can think of so far: Single Virtual Directory Pros Modules can share a single MasterPage Modules can share UserControls (this will be common) Links to other modules are within the same Virtual directory, and thus don't need to be fully qualified. Less chance of having incompatible module versions together. Multiple Virtual Directories Pros Can publish a new version of a single module without disrupting other modules Module is more compartmentalized. Less likely that changes will break other modules. I don't buy those arguments though. First, using load balanced servers (which we will have) we should be able to publish new versions of the project with zero downtime assuming there are no breaking database changes. Second, If something "breaks" another module, then there is either an improper dependency or the break will show up eventually in the other module, when the developers copy over the latest version of the UserControl, MasterPage or dll. As a point of reference, there are about 10 developers on the project for about 50% of their time. The initial development will be about 9 months.
