• no statement parsed and wrong number or types of arguments - cfstoredproc

  - by Travis

  I have an Oracle procedure - editBacklog which I'm calling from a CFM page via cfstoredproc. After several changes to the procedure I started getting ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'EDITBACKLOG'. I've gotten this before and found that if I changed the name of the procedure it starts working again. I changed the name to editBacklog2 and it worked as I expected it to. I changed the name back to editBacklog and got the same error. I changed the name back to editBacklog2 again and started getting ORA-01003: no statement parsed. NOTHING has changed at this point except for the names. I changed the name yet again to editBacklog3 and it works as expected. As of right now editBacklog = ORA-06550 editBacklog2 = ORA-01003 editBacklog3 = works (kinda) This whole thing started when I was trying to fix an ORA-01821: date format not recognized error. I fear when I start changing things I'll start getting the same lame behavior described above. Either Oracle or CF is messing with me and I'll end up liking one of them less because of it. I assume it's probably cfstoredproc caching metadata or something but neither google, livedocs, or OTN have much to say about my situation. I'm not the SA or DBA. Anyone have any ideas?

• TabHost NullPointerException in layout

  - by Chubbs

  I been following the Tab example provided by Google. I am trying to use the XML layout provided to setup a tab layout. I use this XML layout @ http://developer.android.com/guide/tutorials/views/hello-tabwidget.html <?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/textview1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="this is a tab" /> <TextView android:id="@+id/textview2" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="this is another tab" /> <TextView android:id="@+id/textview3" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="this is a third tab" /> </FrameLayout> </LinearLayout> </TabHost> When ever I switch the Layout tab in the Eclipse layout designer I get a NullPointerException: null error inside my Eclipse. This happens also when I try to drag and drop a TabHost, and then a TabWidget into an empty layout file. What am I doing wrong ? this seems pretty simple.

• Visual Studio Conversion Suite

  - by KingPop

  I have this as my conversion program for the "Length", how can I do it the simpliest way instead of keeping the if, elseif, else too much, i do not have much experience and trying to improve my programming skills on visual studio 2008. Basically, I get annoyed with the formulas because I don't know if it is right, I use google but doesn't help because i don't know how to get it right when the program converts from type to type. Public Class Form2 Dim Metres As Integer Dim Centimetres As Integer Dim Inches As Integer Dim Feet As Integer Dim Total As Integer Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ErrorMsg.Hide() End Sub Private Sub btnConvert_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnConvert.Click Metres = 1 Centimetres = 0.01 Inches = 0.0254 Feet = 0.3048 txtTo.Text = 0 If txtFrom.Text <> "" Then If IsNumeric(txtFrom.Text) And IsNumeric(txtTo.Text) Then If cbFrom.Text = "Metres" And cbTo.Text = "Centimetres" Then Total = txtFrom.Text * Metres txtTo.Text = Total ElseIf cbFrom.Text = "Metres" And cbTo.Text = "Inches" Then Total = txtFrom.Text * 100 txtTo.Text = Total ElseIf cbFrom.Text = "Metres" And cbTo.Text = "Feet" Then ElseIf cbFrom.Text = "Centimetres" And cbTo.Text = "Metres" Then ElseIf cbFrom.Text = "Centimetres" And cbTo.Text = "Inches" Then ElseIf cbFrom.Text = "Centimetres" And cbTo.Text = "Feet" Then ElseIf cbFrom.Text = "Inches" And cbTo.Text = "Metres" Then ElseIf cbFrom.Text = "Inches" And cbTo.Text = "Centimetres" Then ElseIf cbFrom.Text = "Inches" And cbTo.Text = "Feet" Then ElseIf cbFrom.Text = "Feet" And cbTo.Text = "Metres" Then ElseIf cbFrom.Text = "Feet" And cbTo.Text = "Centimetres" Then ElseIf cbFrom.Text = "Feet" And cbTo.Text = "Inches" Then End If End If End If End Sub End Class This is the source for what I have done at the moment.

• CCNet: "Failing Tasks : FilteredSourceControl: CheckForModifications" error

  - by Marc

  I've installed CCNet and now I'm trying to set up a link to our repository. When I visit the CCNet dashboard website the project shows up ok, but when I click the Force button I receive this error in the messages column: Failing Tasks : FilteredSourceControl: CheckForModifications If I log into the server as the account which I've specified CCNet should use to connect to the repository, and do an Update on the project by hand (i.e. using SVN.exe or TortoiseSVN) the update works fine. My sourcecontrol section of the CCNet.config file is below. <sourcecontrol type="filtered"> <sourceControlProvider type="svn" autoGetSource="true"> <executable>E:\SVNServer\bin\svn.exe</executable> <trunkUrl> https://bserver.int:4443/trunk </trunkUrl> <workingDirectory>E:\buildserver</workingDirectory> <username>USER</username> <password>PASSWORD</password> </sourceControlProvider> <inclusionFilters> <pathFilter> <pattern>**/*.*</pattern> </pathFilter> </inclusionFilters> </sourcecontrol> Both the cruisecontrol.net website and google seem utterly devoid of any information on this error, other than that it probably relates to the inclusionfilter section in the block above. Can anyone provide any ideas?

• C# program that generates html pages - limit image dimensions on page

  - by Professor Mustard

  I have a C# program that generates a large number of html pages, based on various bits of data and images that I have stored on the file system. The html itself works just fine, but the images can vary greatly in their dimensions. I need a way to ensure that a given image won't exceed a certain size on the page. The simplest way to accomplish this would be through the html itself... if there was some kind of "maxwidth" or "maxheight" property I could set in the html, or maybe a way to force the image to fit inside a table cell (if I used something like this, I'd have to be sure that the non-offending dimension would automatically scale with the one that's being reduced). The problem is, I don't know much about this "fine tuning" kind of stuff in html, and it seems to be a tough thing to Google around for (most of the solutions involve some sort of html specialization; I'm just using plain html). Alternatively, I could determine the width and height of each image at runtime by examining the image in C#, and then setting width/height values in the html if the image's dimensions exceed a certain value. The problem here is that is seems incredibly inefficient to load an entire image into memory, just to get its dimensions. I would need a way to "peek" at an image and just get its size (it could be bmp, jpg, gif or png). Any recommendations for either approach would be greatly appreciated.

• Producing an view of a text's revision history in Python

  - by hekevintran

  I have two versions of a piece of text and I want to produce an HTML view of its revision similar to what Google Docs or Stack Overflow displays. I need to do this in Python. I don't know what this technique is called but I assume that it has a name and hopefully there is a Python library that can do it. Version 1: William Henry "Bill" Gates III (born October 28, 1955)[2] is an American business magnate, philanthropist, and chairman[3] of Microsoft, the software company he founded with Paul Allen. Version 2: William Henry "Bill" Gates III (born October 28, 1955)[2] is a business magnate, philanthropist, and chairman[3] of Microsoft, the software company he founded with Paul Allen. He is American. The desired output: William Henry "Bill" Gates III (born October 28, 1955)[2] is an American business magnate, philanthropist, and chairman[3] of Microsoft, the software company he founded with Paul Allen. He is American. Using the diff command doesn't work because it tells me which lines are different but not which columns/words are different. $ echo 'William Henry "Bill" Gates III (born October 28, 1955)[2] is an American business magnate, philanthropist, and chairman[3] of Microsoft, the software company he founded with Paul Allen.' > oldfile $ echo 'William Henry "Bill" Gates III (born October 28, 1955)[2] is a business magnate, philanthropist, and chairman[3] of Microsoft, the software company he founded with Paul Allen.

• Hello, TabWidget each tab refer to new xml

  - by Clozecall

  Hey everyone I'm using Google's exmaple of Hello, TabWidget but altered it to look like this: main.xml: <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:text="@+layout/text" android:layout_width="fill_parent" android:layout_height="fill_parent" /> <TextView android:id="@+id/textview2" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="this is another tab" /> <TextView android:id="@+id/textview3" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="this is a third tab" /> </FrameLayout> </LinearLayout> java file: public class HelloTabWidget extends TabActivity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TabHost mTabHost = getTabHost(); mTabHost.addTab(mTabHost.newTabSpec("tab_test1").setIndicator("TAB 1").setContent(R.layout.text)); mTabHost.addTab(mTabHost.newTabSpec("tab_test2").setIndicator("TAB 2").setContent(R.id.textview2)); mTabHost.addTab(mTabHost.newTabSpec("tab_test3").setIndicator("TAB 3").setContent(R.id.textview3)); mTabHost.setCurrentTab(0); } } and here is the text.xml in res/layout: <LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" > <TextView android:layout_height="wrap_content" android:layout_width="fill_parent" android:text="This is Tab 1" /> What I'm basically trying to do is have each tab refer to its own xml file rather than all in main.xml, but the text in the first tab doesn't show up.

• Optimized graph drawing for the web

  - by Andreas Petersson

  Having seen some suggestions for graphs, I wonder what's the optimum for my problem. I want to render a directed graph to a servlet/picture that is displayed in the browser. There should be some kind of optimization of position. No dependency to Swing would be preferred. Algorithms are not important, since the structure of the graph is determined by business logic. It would be desired to be able add labels to edges as well. it would be optimal if i can serve this as png/svg. Which library/service would you recommend? clarifications: 1) The question is all about Graphs - like Directed Acyclic Graph - NOT - Charts. 2) flot, Google Charts - cannot plot graphs, only charts, or have i missed something? 3) no i do not need interactivity 4) graphviz would be nice, but the grappa java library is quite outdated and is built upon swing/awt. while it may be theoretically possible to render swing to images, it would not be my favorite way to to so in a server-app. 5) it would be fine to use an online service where the images are not hosted locally. edit: added links to Wikipedia to clarify graph/chart term

• Facebook Connect application inside iframe not working in IE7

  - by Antoine Aubry

  I am building a Facebook Connect application that runs inside a Google gadget. Being a gadget means that the application runs inside an iframe. Inside the application, there is a form that allows registered users to post comments. The submission is made using AJAX, but I get the same results with a normal form. The problem is that I need to get the user's facebook id. In Firefox, it works fine, but on Internet Explorer 7, I get the following error: 'A session key is required for calling this method' I believe that this is due to the way IE handles third-party cookies, because if I go to Internet options / Privacy / Advanced, and check Override automatic cookie handling and accept all cookies, it works fine. I cannot pass the Facebook id from the javascript, because anyone could tamper it. EDIT: If I open the content of the iframe directly, the app works fine. The problem is really due to the IFRAME and IE security model. What am I doing something wrong? How can I work around this problem?

• Sentiment analysis for twitter in python

  - by Ran

  I'm looking for an open source implementation, preferably in python, of Textual Sentiment Analysis (http://en.wikipedia.org/wiki/Sentiment_analysis). Is anyone familiar with such open source implementation I can use? I'm writing an application that searches twitter for some search term, say "youtube", and counts "happy" tweets vs. "sad" tweets. I'm using Google's appengine, so it's in python. I'd like to be able to classify the returned search results from twitter and I'd like to do that in python. I haven't been able to find such sentiment analyzer so far, specifically not in python. Are you familiar with such open source implementation I can use? Preferably this is already in python, but if not, hopefully I can translate it to python. Note, the texts I'm analyzing are VERY short, they are tweets. So ideally, this classifier is optimized for such short texts. BTW, twitter does support the ":)" and ":(" operators in search, which aim to do just this, but unfortunately, the classification provided by them isn't that great, so I figured I might give this a try myself. Thanks! BTW, an early demo is here and the code I have so far is here and I'd love to opensource it with any interested developer.

• Saturated addition of two signed Java 'long' values

  - by finnw

  How can one add two long values (call them x and y) in Java so that if the result overflows then it is clamped to the range Long.MIN_VALUE..Long.MAX_VALUE? For adding ints one can perform the arithmetic in long precision and cast the result back to an int, e.g.: int saturatedAdd(int x, int y) { long sum = (long) x + (long) y; long clampedSum = Math.max((long) Integer.MIN_VALUE, Math.min(sum, (long) Integer.MAX_VALUE)); return (int) clampedSum; } or import com.google.common.primitives.Ints; int saturatedAdd(int x, int y) { long sum = (long) x + (long) y; return Ints.saturatedCast(sum); } but in the case of long there is no larger primitive type that can hold the intermediate (unclamped) sum. Since this is Java, I cannot use inline assembly (in particular SSE's saturated add instructions.) It can be implemented using BigInteger, e.g. static final BigInteger bigMin = BigInteger.valueOf(Long.MIN_VALUE); static final BigInteger bigMax = BigInteger.valueOf(Long.MAX_VALUE); long saturatedAdd(long x, long y) { BigInteger sum = BigInteger.valueOf(x).add(BigInteger.valueOf(y)); return bigMin.max(sum).min(bigMax).longValue(); } however performance is important so this method is not ideal (though useful for testing.) I don't know whether avoiding branching can significantly affect performance in Java. I assume it can, but I would like to benchmark methods both with and without branching.

• How to add a badge to the system generated "More" UITabBarItem

  - by Mark Hoffman

  My app has 6 menu items, so the OS shows the first 4, then shows a "More" item that links to a screen where the user can select the other two. My problem is that I want to show a badge on the More item so that the user knows that one of the menu items that is hidden needs their attention. (It's clear to our users which hidden item the badge represents since one of the hidden items is Settings and the other is current Uploads) I don't know how to access the "More" item since the "items" array on UITabBar only contains the 6 actual UITabBarItems that I've created; it doesn't include the system generated "More" item. I've tried setting the badge on one of the hidden UITabBarItems, but no badge is ever displayed. I didn't find much on Google, which makes me wonder if I'm going about this completely wrong. The iTunes app does the same thing when you download items. They display a More item and attach a badge to it, so I figured I was in good company, but I'll be damned if I see how they did that. (Unless they manually created a UITabBarSystemItemMore item and manually handled displaying the other menu items. Ugh.)

• [iPhone] Background color during flip view animation/transition?

  - by Rob S.

  I have some pretty standing flipping action going on: [UIView beginAnimations:@"swapScreens" context:nil]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES]; [UIView setAnimationDuration:1.0]; [self.view exchangeSubviewAtIndex:0 withSubviewAtIndex:1]; [UIView commitAnimations]; To Apple's credit, this style of animation is amazingly easy to work with. Very cool, and I've been able to animate transitions, flips, fades etc. throughout the app very easily. Question: During the flip transition, the background visible 'behind' the two views during the flip is white and I'd like it to be black. I've: Set the background of the containing view (self.view above) - no dice. I really thought that would work. Set the background of each view to black - no dice. I didn't think this would work although you give different things a shot to understand better :) Google'd like crazy; keep landing on Safari-related listings. Thanks in advance!

• PDF files created on iPad dont display correctly on Windows

  - by user286028

  My iPhone app creates PDF files (in Arial font). The plain iPhone 3.1.x version works great (other than the known issue that PDFs created on the iPhone cant be viewed correctly in Google Docs or the BlackBerry). As I am updating my project for OS 3.2 and the iPad, it works just the same, and the PDFs still look great on the iPhone, iPad and MacOS (Preview app). But now on Windows (Vista), Acrobat 9.3.1 says "Cannot extract the embedded font 'XYZABC+ArialMT'. Some characters may not display or print correctly". And in fact Acrobat then uses some generic font instead of Arial (or whatever other font I try). Quartz 3.2 seems to generate these "random" embedded font names each time it creates a PDF (the XYZABC changes around each time). I can't tell whether the problem is just the somewhat strange "temporary" embedded font name with the plus sign, or the way Quartz 3.2 is embedding fonts. I have tried my existing code (using CGPDFContext* funtions), and also the newly supported UIGraphics* functions, with the same results. Has anyone else tried creating PDFs on the iPad yet and gotten them to display correctly on Windows?

• How Can I Prevent Memory Leaks in IE Mobile?

  - by Jake Howlett

  Hi All, I've written an application for use offline (with Google Gears) on devices using IE Mobile. The devices are experiencing memory leaks at such a rate that the device becomes unusable over time. The problem page fetches entries from the local Gears database and renders a table of each entry with a link in the last column of each row to open the entry ( the link is just onclick="open('myID')" ). When they've done with the entry they return to the table, which is RE-rendered. It's the repeated building of this table that appears to be the problem. Mainly the onclick events. The table is generated in essence like this: var tmp=""; for (var i=0; i<100; i++){ tmp+="<tr><td>row "+i+"</td><td><a href=\"#\" id=\"LINK-"+i+"\""+ " onclick=\"afunction();return false;\">link</a></td></tr>"; } document.getElementById('view').innerHTML = "<table>"+tmp+"</table>"; I've read up on common causes of memory leaks and tried setting the onclick event for each link to "null" before re-rendering the table but it still seems to leak. Anybody got any ideas? In case it matters, the function being called from each link looks like this: function afunction(){ document.getElementById('view').style.display="none"; } Would that constitute a circular reference in any way?

• DB2 with mod_perl not working, works fine in CGI

  Hi, I'm having issues with getting DBI's IBM DB2 driver to work with mod_perl. My test script is: #!/usr/bin/perl use CGI; use Data::Dumper; use DBI; $q = CGI->new; print $q->header; print $q->start_html(); $dsn = "DBI:DB2:SAMPLE"; $username = "username"; $password = "password"; $dbc = DBI->connect($dsn, $username, $password); $sth = $dbc->prepare("SELECT * FROM SOME_TABLE WHERE FIELD='SOMETHING'"); $sth->execute(); $row = $sth->fetchrow_hashref(); print "<pre>".$q->escapeHTML(Dumper($row))."</pre>"; print $q->end_html; This script works as CGI but not under mod_perl. I get this error in apache's error log: DBD::DB2::dr connect warning: [unixODBC][Driver Manager]Data source name not found, and no default driver specified at /usr/lib/perl5/site_perl/5.8.8/Apache/DBI.pm line 190.

• Java (Tomcat): how to configure a cookieless subdomain to serve static content

  - by Webinator

  One of the tip given by both Google and Yahoo! to speed up webpages loading is to configure a cookieless subdomain to server static content. How do you configure a "cookieless subdomain" using Tomcat in standalone mode (this question is not about how to use Apache to serve static content in a cookieless-way, but about how to do it in Tomcat-standalone mode)? Note that I don't care about filters supporting If-Modified-Since nor care about filters supporting gzipping: the static content I'm serving is forever cacheable (or its name will change) and it is already compressed data (so gzip would only slow down the transfer). Do I need two different Tomcat webapps? (one "cookiefull" and one "cookieless") Do I need two different servlets? (as of now I've got only one dispatcher/controller servlet). Why would a "regular" link to, say, a static image be called in a cookiefull way when it would be on the same domain as the main webapp and then be called in a "cookie-less" way when it is on a subdomain? I don't understand exactly what is going on: is it the browser that decides to append or not cookies to the query? If so, why would it not append the cookies to a static query on a "cookieless" subdomain. Any example as to what is going on behind the scene is most welcome :)

• Getting Indy Error "Could not bind socket. Address and port are already in use"

  - by M Schenkel

  I have developed a Delphi web server application (TWebModule). It runs as a ISAPI DLL on Apache under Windows. The application in turn makes frequent https calls to other web sites using the Indy TIdHTTP component. Periodically I get this error when using the TIdHTTP.get method: Could not bind socket. Address and port are already in use Here is the code: IdSSLIOHandlerSocket1 := TIdSSLIOHandlerSocketOpenSSL.create(nil); IdHTTP := TIdHTTP.create(nil); idhttp.handleredirects := True; idhttp.OnRedirect := DoRedirect; with IdSSLIOHandlerSocket1 do begin SSLOptions.Method := sslvSSLv3; SSLOptions.Mode := sslmUnassigned; SSLOptions.VerifyMode := []; SSLOptions.VerifyDepth := 2; end; with IdHTTP do begin IOHandler := IdSSLIOHandlerSocket1; ProxyParams.BasicAuthentication := False; Request.UserAgent := 'Test Google Analytics Interface'; Request.ContentType := 'text/html'; request.connection := 'keep-alive'; Request.Accept := 'text/html, */*'; end; try idhttp.get('http://www.mysite.com......'); except ....... end; IdHTTP.free; IdSSLIOHandlerSocket1.free; I have read about the reusesocket method, which can be set on both the TIdHttp and TIdSSLLIOHandlerSocketOpenSSL objects. Will setting this to rsTrue solve my problems? I ask because I have not been able to replicate this error, it just happens periodically. Other considerations: I know multiple instances of TWebModule are being spawned. Would wrapping all calls to TIdHttp.get within a TCriticalSection solve the problem?

• DDMS won't load (or doesn't parse?) KML file

  - by nderraugh

  I can't get DDMS to load any KML files. I have a KML file for example with the following in it: <?xml version="1.0" encoding="UTF-8"?> <kml xmlns="http://www.opengis.net/kml/2.2"> <Placemark> <name>Simple placemark</name> <description>Attached to the ground.

That doesn't work. I even tried the Google Earth solution suggested at the same link. I'm using SDK 1.5_r2. I am doing something wrong or missing something?

  I've just upgraded my Mac to Snow Leopard and got my Rails environment up and running. The only difference -- OSX aside -- with my previous install is that I'm now running ruby 1.8.7 (2008-08-11 patchlevel 72) [universal-darwin10.0] (Snow Leopard default) rather than 1.8.6. I'm now seeing deprecation warnings relating to OpenSSL when I run my code: warning: argumtents for OpenSSL::Cipher::Cipher#encrypt and OpenSSL::Cipher::Cipher#decrypt were deprecated; use OpenSSL::Cipher::Cipher#pkcs5_keyivgen to derive key and IV Example of my code which is causing these warnings (it decodes an encrypted string) on line 4: 1. def decrypt(data) 2. encryptor = OpenSSL::Cipher::Cipher.new('DES-EDE3-CBC') 3. key = "my key" 4. encryptor.decrypt(key) 5. text = encryptor.update(data) 6. text << encryptor.final 7. end I'm struggling to understand how I can resolve this, and Google isn't really helping. Should I try and downgrade to Ruby 1.8.6 (and if so, what's the best way of doing this?), should I try and just hide the warnings (bury my head in the sand?!) or is there an easy fix I can apply in the code?

• Auto load a specific link at various time intervals

  - by user228837

  Here's what I need to do. I'm using Google Chrome. I have page that auto-reloads every 5 seconds using a script: javascript: timeout=prompt("Set timeout [s]"); current=location.href; if(timeout>0) setTimeout('reload()',1000*timeout); else location.replace(current); function reload() { setTimeout('reload()',1000*timeout); fr4me='<frameset cols=\'*\'>\n<frame src=\''+current+'\'/>'; fr4me+='</frameset>'; with(document){write(fr4me);void(close())}; } I found that script by Googling. The reason why the page auto-reloads every 5 seconds is I'm waiting for a specific link or url to appear in the page. It appears at random times. Once I see the link I'm waiting for, I immediately click the link. That's fine. But I want more. What I want is the page will auto-reload and I want it to auto-detect the the link I'm waiting for. Once the script finds the link I'm waiting for, it automatically loads that link on a new tab or page. For example, I'm auto-reloading www.example.com. I'm waiting for a specific url "BUY NOW". When the page auto-reloads, it checks if there's a url "BUY NOW". If it sees one, it should automatically open that link. Thanks.

• "Executing SQL directly; no cursor" error when using SCOPE_IDENTITY

  - by Chris

  There wasn't much on google about this error, so I'm askin here. I'm switching a PHP web application from using MySQL to SQL Server 2008 (using ODBC, not php_mssql). Running queries or anything else isn't a problem, but when I try to do scope_identity (or any similar functions), I get the error "Executing SQL directly; no cursor". I'm doing this immediately after an insert, so it should still be in scope. Running the same insert statement then query for the insert ID works fine in SQL Server Management Studio. Here's my code right now (everything else in the database wrapper class works fine for other queries, so I'll assume it isn't relevant right now): function insert_id(){ $x = $this->query_first("SELECT SCOPE_IDENTITY('session_log') as insert_id"); echo "($x)"; return $x; } query_first being a function that returns the first result from the first field of a query (basically the equivalent of execute_scalar() on .net). The full error message: Warning: odbc_exec() [function.odbc-exec]: SQL error: [Microsoft][SQL Server Native Client 10.0][SQL Server]Executing SQL directly; no cursor., SQL state 01000 in SQLExecDirect in C:[...]\Database_MSSQL.php on line 110
