• .net user control event handler lost on postback

  - by user154008

  I have a menu usercontrol called LeftMenu that has a bulletedlist of linkitems. It's on the ascx page as such: <asp:BulletedList ID="PublisherList" DisplayMode="LinkButton" OnClick="PublisherList_Click" cssClass="Menu" runat="server"></asp:BulletedList> I databind the list in the page_load under if(!isPostBack) I'm having an issue on a page that loads the control. When the page first loads, the event handler fires. However, when the page posts back it no longer fires and in IE8, when I'm debugging, I get "Microsoft JScript runtime error: Object expected" in Visual Studio pointing at "doPostBack('LeftMenu$PublisherList','0')." In FF I don't get the error, but nothing happens. I'm **not loading the control dynamically, it's loaded on the aspx page using: <%@ Register TagPrefix="Standards" TagName="LeftMenu" Src="LeftMenu.ascx" %> <Standards:LeftMenu ID="LeftMenu" runat="server"/> Any ideas of where I'm losing the event handler? I just realized this is happening on another user control I have as well. A text box and a button and I'm using the default button to make sure pressing the enter key uses that button. .Net converts that in the html to: <div id="SearchBarInclude_SearchBar" onkeypress="javascript:return WebForm_FireDefaultButton(event, 'SearchBarInclude_QuickSearchButton')"> so as soon as i enter a key in the box I get a javascript error at the line saying "object expected." It seems like the two issues are related. Edit Again: I think I need to clarify. It's not that I'm clicking on the menu item and it can't find the selected item on postback. I have this search page with the left navigation on it and then the main content of the page is something that causes a postback. Everything is fine with this postback. Once that page has been posted back, now if I click on the bulleted list in the left navigation I get a javascript error and it fails. The page_init for the LeftMenu control is never called.

• xstream and ibm j9 sdk incompatibilities on linux

  - by Yoni

  I encountered an incompatibility with xstream and IBM J9 jdk (the 32bits version). Everything worked fine when I used sun jdk but fails on IBM jdk (on linux only. on windows it's ok with both jdks). When debugging, the error appears to be that xstream uses a java.util.TreeSet internally but the set's iterator returns elements in the wrong order (I know this sounds very strange, but this is the behavior that I saw). Googling for related bugs didn't give any meaningful results I tried upgrading pretty much any component possible but no luck. I tried the following configurations: ibm jdk 1.6 SR 7 (bundled with WebSphere 7.0.0.9), xstream 1.2.2 ibm jdk 1.6 SR 8, xstream 1.2.2 ibm jdk 1.6 SR 8, xstream 1.3.1 (I tried those both with tomcat and with WebSphere server, so actually there are 6 configurations using IBM jdk). The code in question is in class com.thoughtworks.xstream.core.DefaultConverterLookup, around line 44. It uses an iterator from class com.thoughtworks.xstream.core.util.PrioritizedList, which uses a custom comparator, but all the comparator does is compare integers (the priorities). Has anyone seen this before? Any idea what can I do or change?

• What is likely cause of Android runtime exception "No suitable Log implementation" related to loggin

  - by M.Bearden

  I am creating an Android app that includes a third party jar. That third party jar utilizes internal logging that is failing to initialize when I run the app, with this error: "org.apache.commons.logging.LogConfigurationException: No suitable Log implementation". The 3rd party jar appears to be using org.apache.commons.logging and to depend on log4j, specifically log4j-1.2.14.jar. I have packaged the log4j jar into the Android app. The third party jar was packaged with a log4j.xml configuration file, which I have tried packaging into the app as an XML resource (and also as a raw resource). The "No suitable Log implementation" error message is not very descriptive, and I have no immediate familiarity with Java logging. So I am looking for likely causes of the problem (what class or configuration resources might I be missing?) or for some debugging technique that will result in a different error message that is more explicit about the problem. I do not have access to source code for the 3rd party jar. Here is the exception stack trace. When I run the app, I get the following exception as soon as one of the third party jar classes attempts to initialize its internal logging. DEBUG/AndroidRuntime(15694): Shutting down VM WARN/dalvikvm(15694): threadid=3: thread exiting with uncaught exception (group=0x4001b180) ERROR/AndroidRuntime(15694): Uncaught handler: thread main exiting due to uncaught exception ERROR/AndroidRuntime(15694): java.lang.ExceptionInInitializerError ERROR/AndroidRuntime(15694): Caused by: org.apache.commons.logging.LogConfigurationException: No suitable Log implementation ERROR/AndroidRuntime(15694): at org.apache.commons.logging.impl.LogFactoryImpl.discoverLogImplementation(LogFactoryImpl.java:842) ERROR/AndroidRuntime(15694): at org.apache.commons.logging.impl.LogFactoryImpl.newInstance(LogFactoryImpl.java:601) ERROR/AndroidRuntime(15694): at org.apache.commons.logging.impl.LogFactoryImpl.getInstance(LogFactoryImpl.java:333) ERROR/AndroidRuntime(15694): at org.apache.commons.logging.impl.LogFactoryImpl.getInstance(LogFactoryImpl.java:307) ERROR/AndroidRuntime(15694): at org.apache.commons.logging.LogFactory.getLog(LogFactory.java:645) ERROR/AndroidRuntime(15694): at org.apache.commons.configuration.ConfigurationFactory.<clinit>(ConfigurationFactory.java:77)

• Displaying recntangles in game window with XNA

  - by blerh

  I want to divide my game grid into an array of rectangles. Each rectangle is 40x40 and there are 14 rectangles in every column, with a total of 25 columns. This covers a game area of 560x1000. This is the code I have set up to make the first column of rectangles on the game grid: Rectangle[] gameTiles = new Rectangle[15]; for (int i = 0; i <= 15; i++) { gameTiles[i] = new Rectangle(0, i * 40, 40, 40); } I'm pretty sure this works, but of course I cannot confirm it because rectangles do not render on the screen for me to physically see them. What I would like to do for debugging purposes is to render a border, or fill the rectangle with color so I can see it on the game itself, just to make sure this works. Is there a way to make this happen? Or any relatively simple way I can just make sure that this works? Thank you very much.

• does lucene search function work in large size document?

  - by shaon-fan

  Hi,there I have a problem when do search with lucene. First, in lucene indexing function, it works well to huge size document. such as .pst file, the outlook mail storage. It can build indexing file include all the information of .pst. The only problem is to large sometimes, include very much words. So when i search using lucene, it only can process the front part of this indexing file, if one word come out the back part of the indexing file, it couldn't find this word and no hits in result. But when i separate this indexing file to several parts in stupid way when debugging, and searching every parts, it can work well. So i want to know how to separate indexing file, how much size should be the limit of searching? cheers and wait 4 reply. ++++++++++++++++++++++++++++++++++++++++++++++++++ hi,there, follow Coady siad, i set the length to max 2^31-1. But the search result still can't include what i want. simply, i convert the doc word to string array[] to analyze, one doc word has 79680 words include the space and any symbol. when i search certain word, it just return 300 count, actually it has more than 300 results. The same reason, when i search a word in back part of the doc, it also couldn't find. //////////////set the length idexwriter.SetMaxFieldLength(2147483647); ////////////////////search IndexSearcher searcher = new ndexSearcher(Program.Parameters["INDEX_LOCATION"].ToString()); Hits hits = searcher.Search(query); This is my code, as others same. I found that problem when i need to count every word hits in a doc. So i also found it couldn't search word in back part of doc. pls help me to find, is there any set searcher length somewhere? how u meet this problem.

• Getting a lightweight installation of java eclipse.

  - by liam

  Having dealt with yet another stupid eclipse problem, I want to try to get the lightest, most minimal eclipse installation as possible. To be clear, I use eclipse for two things: - Editing Java - Debugging Java Everything else I do through emacs/zsh (editing jsp/xml/js, file management, svn check-in, etc). I have not found any aspect of working in eclipse to do these tasks to be efficient or even reliable, so I do not want plug-ins that relate to it. From the eclipse.org site, this is the lightest install of eclipse that they have, and I don't want any of those things (bugzilla, mylyn, cvs, xml_ui), and have actually had problems with each of them even though I do not use them. So what is the minimal build I can get that will: 1) Ignore svn metadata 2) Includes the full-featured editor (intellisense and type-finding) 3) Includes the full-featured debugger (standard eclipse/jdk) Does not have any extra plug-ins, platforms, or "integrations" with other platforms, specifically, I don't want to deal with plug-ins relating to: Maven, JSP Validation, Javascript editing or validation, CVS or SVN, Mylyn, Spring or Hibernate "natures", app servers like a bundled tomcat/glassfish/etc, J2EE tools, or anything of the like. I do primarily spring/hibernate/web-mvc apps, and have never dealt with an eclipse plug-in that handles any of it gracefully, I can work effectively with my own toolset, but eclipse extensions do nothing but get in the way. I have worked with plain eclipse up to Ganymede, MyEclipse (up to 7.5), and the latest version of Spring-SourceTools, and find that they are all saddled with buggy useless plug-ins (though the combination is always different). Switching to netbeans/intellij is not an option, and my teammates work with svn-controlled .class/.project files, so it pretty much has to be eclipse. Does anyone have any good advice on how I can save a few grey hairs?

• prevent javascript in the WMD editor's preview box

  - by Justin Grant

  There are many SO questions (e.g. here and here) about how to do server-side scrubbing of Markdown produced by the WMD editor to ensure the HTML generated doesn't contain malicious script, like this: <img onload="alert('haha');" src="http://www.google.com/intl/en_ALL/images/srpr/logo1w.png" /> Unfortunately, this still allows script to show up in the WMD client's preview box. I doubt this is a big deal since if you're scrubbing the HTML on the server, an attacker can't save the bad HTML so no one else will be able to see it later and have their cookies stolen or sessions hijacked by the bad script. But it's still kinda odd to allow an attacker to run any script in the context of your site, and it's probably a bad idea to allow the client preview window to allow different HTML than your server will allow. StackOverflow has clearly plugged this hole. How did they do it? [NOTE: I already figured this out but it required some tricky javascript debugging, so I'm answering my own question here to help others who may want to do ths same thing]

• Windows service hangs

  - by Ram

  Hi, I have a webdav client-server application. I'm using Cassini webserver to host the webdav server. One important thing here is that I start and Stop my webserver using a windows service. Now, I start my windows service and I attach my webdav server application's debugger to the windows service. Everything used to go fine, that is I could connect to the server using my webdav client, debug the server code. However, a couple of days back, when I tried to debug my webdav server application, which in turn is attached to a windows service, my computer freezes while I'm in the midst of debugging the server app. The freeze does not occur at the same line every time and is therefore not predictable. Every time this happens, I would not be able to do anything at all with my computer except to reboot the system using the power button. What could be the problem? Could it be the service that is freezing or something else? Any help? Thanks, Ram

• Javascript library: to obfuscate or not to obfuscate - that is the question

  - by morpheous

  I need to write a GUI related javascript library. It will give my website a bit of an edge (in terms of functionality I can offer) - up until my competitors play with it long enough to figure out how to write it by themselves. I can accept the fact that it will be emulated over time - thats par for the course (its part of business). However, what I cannot bear, is the idea of effectively, simply handing over all the hard work that would have gone into the library to my competitors, by using plain javascript that anyone can download and use. It is an established fact that no none in the industry I am "attacking" has this functionality, so the value of such a library is undeniable and is not up for discussion (i.e. thats not what I'm asking here). What I am seeking to find out are the pros and cons of obfuscating a javascript library, so that I can come to a final decision. Two of my biggest concerns are debugging, and subtle errors that may be introduced by the obfuscator. I would like to know: How can I manage those risks (being able to debug faulty code, ensuring/minimizing against obfuscation errors) Are there any good quality industry standard obfuscators you can recommend (preferably something you use yourself). What are your experiences of using obfuscated code in a production environment?

• PDO Database Connections Problem

  - by Metropolis

  Hey Everyone, Over a year ago I created my own database classes which use PDO, and handle all preparing, executing, and closing connections. These classes have been working great up until now. There are two different database severs I am grabbing from, MySQL, and MS SQL Express. I am retrieving an employee id from the MySQL server and using it to get that employees information from the MS SQL server. There are about 11k records coming from the MySQL server and my program is only making it through 1200 before crashing with an error like the following. Connection failed (odbc:Driver=FreeTDS;Servername=MSSQLExpress;Database=SMDINC) Class (PDOException) SQLSTATE[08001] SQLDriverConnect: 0 [unixODBC][FreeTDS][SQL Server]Unable to connect to data source It seems like the program is not able to connect to the data source, but it is running the exact same query about 30 times before this and having no problem. Also, I have thoroughly checked all of the data coming into the query and it all looks fine. I believe the issue may be that there are to many connections being created, but I have tried to close all connections in many different places, and nothing seems to be fixing the problem. Any debugging help, or suggestions would be appreciated! Craig Metrolis

• ASP.NET MVC Posted date field comes in as 1/1/0001

  - by engil

  Just started working with .NET and MVC(1). I'm having a problem wherein in my add action the entered date for some reason ends up as 1/1/0001 instead of what is entered thus causing a date overflow. In my model, this field ("Added") is is of type datetime and does not allow nulls. In my controller I have: public ActionResult Add() { Instance instance = new Instance() { Added = DateTime.Now, Active = true }; return View(instance); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Add(Instance instance) { if (ModelState.IsValid) { try { System.Diagnostics.Trace.Write("test"); instanceRepository.Add(instance); instanceRepository.Save(); return RedirectToAction("Details", new { id = instance.InstanceID }); } catch { ModelState.AddRuleViolations(instance.GetRuleViolations()); } } return View(instance); } And in my view I have: <div class="editor-label"> <%= Html.LabelFor(model => model.Added) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Added,String.Format("{0:g}",Model.Added))%> <%= Html.ValidationMessageFor(model => model.Added) %> When I first go to Instances/Add the default value is set correctly, however as soon as I submit the date turns into 1/1/0001 (from my understanding this indicates that it was either null or in an unrecognizable format) When I debug and palce a watch on Request.Form I see the date coming in encoded ie Request.Form {Added=4%2f9%2f2010+8%3a24%3a39+AM} - is this an issue? I know its probably not enough information to make a conlusive determination on why this is failing, but if someone could provide some good debugging tips on how to determine where the submitted date is getting munged I'd really appreciate it.

• Pros and cons of each JEE server for developing within Eclipse

  - by Thorbjørn Ravn Andersen

  Eclipse JEE has a lot of server adapters allowing development against many different application servers like JBoss, Glassfish and WebSphere. Frequently you can benefit from using another server for developing new features than for production, simply because it may be able to deploy changes much faster and when the functionality is in place, you can iron out bugs for the production platform. Unfortunately finding that server is a time consuming process, where others experience is invaluable. If you have experience with any server with an Eclipse Server Adapter, please add your findings and your recommendation. I believe that the following is of interest: Does saving a file trigger an update in the server, giving save edit+reload browser functionality? How fast is a deployment? (Saved a JSP? Java class? Static file?) Can the actual server be downloaded by the Server Adapter Wizard allowing for easy installation? Are there known bugs and issues with suitable work-arounds? Is debugging fully supported? Is profiling? Would you recommend this server? Note: Eclipse can also work with Tomcat but that is a web container, which cannot deploy EAR files.

• UpdateModel not working consistently for me if a ddl gets hidden by jQuery

  - by awrigley

  Hi My jQuery code hides a ddl under certain circumstances. When this is the case, after submitting the form, using the UpdateModel doesn't seem to work consistently. My code in the controller: // POST: /IllnessDetail/Edit [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(IllnessDetail ill) { IllnessDetailFormViewModel mfv = new IllnessDetailFormViewModel(ill); if (ModelState.IsValid) { try { IllnessDetail sick = idr.GetLatestIllnessDetailByUsername(User.Identity.Name); UpdateModel(sick); idr.Save(); return RedirectToAction("Current", "IllnessDetail"); } catch { ModelState.AddRuleViolations(mfv.IllnessDetail.GetRuleViolations()); } } return View(new IllnessDetailFormViewModel(ill)); } I have only just started with MVC, and working under a deadline, so am still hazy as to how UpdateModel works. Debugging seems to reveal that the correct value is passed in to the action method: public ActionResult Edit(IllnessDetail ill) And the correct value is put into sick in the following line: IllnessDetailFormViewModel mfv = new IllnessDetailFormViewModel(ill); However, when all is said, done and returned to the client, what displays is the value of: sick.IdInfectiousAgent instead of the value of: ill.IdInfectiousAgent The only reason I can think of is that the ddlInfectiousAgent has been hidden by jQuery. Or am I barking up the wrong lamp post? Andrew

• Rapid calls to fread crashes the application

  - by Slynk

  I'm writing a function to load a wave file and, in the process, split the data into 2 separate buffers if it's stereo. The program gets to i = 18 and crashes during the left channel fread pass. (You can ignore the couts, they are just there for debugging.) Maybe I should load the file in one pass and use memmove to fill the buffers? if(params.channels == 2){ params.leftChannelData = new unsigned char[params.dataSize/2]; params.rightChannelData = new unsigned char[params.dataSize/2]; bool isLeft = true; int offset = 0; const int stride = sizeof(BYTE) * (params.bitsPerSample/8); for(int i = 0; i < params.dataSize; i += stride) { std::cout << "i = " << i << " "; if(isLeft){ std::cout << "Before Left Channel, "; fread(params.leftChannelData+offset, sizeof(BYTE), stride, file + i); std::cout << "After Left Channel, "; } else{ std::cout << "Before Right Channel, "; fread(params.rightChannelData+offset, sizeof(BYTE), stride, file + i); std::cout << "After Right Channel, "; offset += stride; std::cout << "After offset incr.\n"; } isLeft != isLeft; } } else { params.leftChannelData = new unsigned char[params.dataSize]; fread(params.leftChannelData, sizeof(BYTE), params.dataSize, file); }

• How to safely transfer reference to object across window?

  - by Morgan Cheng

  I'm debugging a web application. Javasript in one window create one object and use it as argument to invoke global method in another window. Pseudo code is like below. var obj = new Foo(); anotherWin.bar(obj); In anotherWin, the argument is stored in global variable. var g_obj; function bar(obj) { g_obj = obj; ... } When other function tries to reference g_obj.Id, it throws exception "Cannot evaluate expression". This happens in IE8.0.7600.16385 on Windows 7. In Visual Studio debugger, when this exception happens, the g_obj shows as {...} It looks all its properties are lost. Perhaps the root reason is the object is created in one window but only referenced in another window. The object might be garbage-collected at any time. Is there any way to work around this?

• Objective-C: Getting the True Class of Classes in Class Clusters

  - by TechZen

  Recently while trying to answer a questions here, I ran some test code to see how Xcode/gdb reported the class of instances in class clusters. (see below) In the past, I've expected to see something like: PrivateClusterClass:PublicSuperClass:NSObject Such as this (which still returns as expected): NSPathStore2:NSString:NSObject ... for a string created with +[NSString pathWithComponents:]. However, with NSSet and subclass the following code: - (void)applicationDidFinishLaunching:(UIApplication *)application { NSSet *s=[NSSet setWithObject:@"setWithObject"]; NSMutableSet *m=[NSMutableSet setWithCapacity:1]; [m addObject:@"Added String"]; NSMutableSet *n = [[NSMutableSet alloc] initWithCapacity:1]; [self showSuperClasses:s]; [self showSuperClasses:m]; [self showSuperClasses:n]; [self showSuperClasses:@"Steve"]; } - (void) showSuperClasses:(id) anObject{ Class cl = [anObject class]; NSString *classDescription = [cl description]; while ([cl superclass]) { cl = [cl superclass]; classDescription = [classDescription stringByAppendingFormat:@":%@", [cl description]]; } NSLog(@"%@ classes=%@",[anObject class], classDescription); } ... outputs: // NSSet *s NSCFSet classes=NSCFSet:NSMutableSet:NSSet:NSObject //NSMutableSet *m NSCFSet classes=NSCFSet:NSMutableSet:NSSet:NSObject //NSMutableSet *n NSCFSet classes=NSCFSet:NSMutableSet:NSSet:NSObject // NSString @"Steve" NSCFString classes=NSCFString:NSMutableString:NSString:NSObject The debugger shows the same class for all Set instances. I know that in the past the Set class cluster did not return like this. What has changed? (I suspect it is a change in the bridge from Core Foundation.) What class cluster report just a generic class e.g. NSCFSet and which report an actual subclass e.g. NSPathStore2? Most importantly, when debugging how do you determine the actual class of a NSSet cluster instance?

• GWT Animation final value is not respected

  - by brad

  I have a FlowPanel that I'm trying to animate back and forth like an iphone nav. (See this post for my original question on how to do this) So I have it "working" with the code shown below. I say working in quotes because I'm finding that my final position of my scroller is not precise and always changes when scrolling. The GWT.log always says the actual values I'm looking for, so for instance with the call below to scrollTo, my GWT.log says: ScrollStart: 0 scrollStop: -246 But when I actually analyze the element in fireBug, its css, left position is never exactly -246px. Sometimes it's off by as much as 10px so my panel has just stopped scrolling before being finished. The worst part is that this nav animates back and forth, so subsequent clicks can really throw it off, and I need pixel perfect positioning otherwise the whole things looks off. I don't even know where to start with debugging this other than what I've already done. Any tips are appreciated. Code to call animation scroller = new Scroller(); scroller.scrollTo(-246,400); Animation Code public class Scroller extends Animation { private FlowPanel scroller; private final Element e; public Scroller(){ scroller = new FlowPanel(); e = scroller.getElement(); } public void scrollTo(int position, int milliseconds) { scrollStart = e.getOffsetLeft(); scrollStop = position; GWT.log("ScrollStart: " + scrollStart + " scrollStop: " + scrollStop); run(milliseconds); } @Override protected void onUpdate(double progress) { double position = scrollStart + (progress * (scrollStop - scrollStart)); e.getStyle().setLeft(position, Style.Unit.PX); } }

• Php index page utitlizing an idea for a superswitch...

  I dont know if this is a great idea...or a crap one. But I was thinking I may use one page to display all my pages using includes. Here is what my index.php would look like...on the functions include there is a function called "superSwitch" which will determine what requested page will be included....for instance if I do a get ?a=a it will goto the function superSwitch(a) superSwitch will take it and associate it with (login.php) then respond with such... here is the code for the index.php...please let me know if this makes sense and might work, or should I just stick to long blocks of code (which is why I am trying this because I hate long pages full of code...) of course as you can tell it is not actually including anything yet...the print is for debugging purposes. :) Thanks, Matt <?php //includes Functions include_once('inc/func.inc.php'); //set superget variable $superget = @$_GET['a']; //check if superget is set or null if (!$superget) { echo "Nothing Requested :)"; } else { //sanitizes the superget request $supergetr = supergetSanitize($superget) //uses the result "good" or "nogood" to determine what happens if ( $supergetr == "good" ) { //pulls superSwitch value of the request $ssresult = superSwitch($superget); print_r ($ssresult); } //if the sanitize is nogood else { //the superSwitch is instructed to respond with a 404 page $superget = "404" $ssresult = superSwitch($superget); print_r ($ssresult); } } ?>

  We're going through a round of sql-server stored procedure optimizations. The one recommendation we've found that clearly applies for us is 'SET NOCOUNT ON' at the top of each procedure. (Yes, I've seen the posts that point out issues with this depending on what client objects you run the stored procedures from but these are not issues for us.) So now I'm just trying to add in a bit of common sense. If the benefit of SET NOCOUNT ON is simply to reduce network traffic by some small amount every time, wouldn't it also make sense to turn off all the PRINT statements we have in the stored procedures that we only use for debugging? I can't see how it can hurt performance. OTOH, it's a bit of a hassle to implement due to the fact that some of the print statements are the only thing within else clauses, so you can't just always comment out the one line and be done. The change carries some amount of risk so I don't want to do it if it isn't going to actually help. But I don't see eliminating print statements mentioned anywhere in articles on optimization. Is that because it is so obvious no one bothers to mention it?

• c++ function scope

  - by Myx

  I have a main function in A.cpp which has the following relevant two lines of code: B definition(input_file); definition.Print(); In B.h I have the following relevant lines of code: class B { public: // Constructors B(void); B(const char *filename); ~B(void); // File input int ParseLSFile(const char *filename); // Debugging void Print(void); // Data int var1; double var2; vector<char* > var3; map<char*, vector<char* > > var4; } In B.cpp, I have the following function signatures (sorry for being redundant): B::B(void) : var1(-1), var2(numeric_limits<double>::infinity()) { } B::B(const char *filename) { B *def = new B(); def->ParseLSFile(filename); } B::~B(void) { // Free memory for var3 and var 4 } int B::ParseLSFile(const char *filename) { // assign var1, var2, var3, and var4 values } void B::Print(void) { // print contents of var1, var2, var3, and var4 to stdout } So when I call Print() from within B::ParseLSFile(...), then the contents of my structures print correctly to stdout. However, when I call definition.Print() from A.cpp, my structures are empty or contain garbage. Can anyone recommend the correct way to initialize/pass my structures so that I can access them outside of the scope of my function definition? Thanks.

• Execute Stored Procedure from Classic ASP

  - by Jaco Pretorius

  For some fantastic reason I find myself debugging a problem in a Classic ASP page (at least 10 years of my life lost in the last 2 days). I'm trying to execute a stored procedure which contains some OUT parameters. The problem is that one of the OUT parameters is not being populated when the stored procedure returns. I can execute the stored proc from SQL management studio (this is 2008) and all the values are being set and returned exactly as expected. declare @inVar1 varchar(255) declare @inVar2 varchar(255) declare @outVar1 varchar(255) declare @outVar2 varchar(255) SET @inVar2 = 'someValue' exec theStoredProc @inVar1 , @inVar2 , @outVar1 OUT, @outVar2 OUT print '@outVar1=' + @outVar1 print '@outVar2=' + @outVar2 Works great. Fantastic. Perfect. The exact values that I'm expecting are being returned and printed out. Right, since I'm trying to debug a Classic ASP page I copied the code into a VBScript file to try and narrow down the problem. Here is what I came up with: Set Conn = CreateObject("ADODB.Connection") Conn.Open "xxx" Set objCommandSec = CreateObject("ADODB.Command") objCommandSec.ActiveConnection = Conn objCommandSec.CommandType = 4 objCommandSec.CommandText = "theStoredProc " objCommandSec.Parameters.Refresh objCommandSec.Parameters(2) = "someValue" objCommandSec.Execute MsgBox(objCommandSec.Parameters(3)) Doesn't work. Not even a little bit. (Another ten years of my life down the drain) The third parameter is simply NULL - which is what I'm experiencing in the Classic ASP page as well. Could someone shed some light on this? Am I completely daft for thinking that the classic ASP code would be the same as the VBScript code? I think it's using the same scripting engine and syntax so I should be ok, but I'm not 100% sure. The result I'm seeing from my VBScript is the same as I'm seeing in ASP.

• SIGABRT on iPhone when changing xib

  - by Boz

  I've just finished off an app for the iPhone which, until today, ran fine on the iPhone simulator and actual devices. I tried changing the xib which is loaded in the applicationDidFinishLaunching method in my application delegate class - all I did was change the string in initWithNibName. When I launch the app on the simulator, the Default.png image is shown, then the app crashes with an uncaught exception. When running on a device, the Default.png image is shown for about 10 seconds, the UI is never loaded and I get 'GDB: Program received signal: "SIGABRT".' on the Xcode status bar. Debugging shows that applicationDidFinishLaunching is never actually reached before the app crashes. Setting the starting xib back to the original solves the issue, but now I've made a change and saved it in the Interface Builder and the app shows the same issues as above - I've made no code changes at all. Is this a memory issue, or a known issue of a common mistake? NOTE: I've made no code changes whatsoever, and the only changes I've made to the xib are cosmetic, the IBOutlets are all intact.

• Some clarification needed about synchronous versus asynchronous asio operations

  - by Old newbie

  As far as I know, the main difference between synchronous and asynchronous operations. I.e. write() or read() vs async_write() and async_read() is that the former, don't return until the operation finish -or error-, and the last ones, returns inmediately. Due the fact that the asynchronous operations are controlled by an io_service.run() that does not finish until the controlled operations has finalized. It seems to me that in sequencial operations as those involved in TCP/IP connections with protocols such as POP3, in which the operaton is a sequence such as: C: <connect> S: Ok. C: User... S: Ok. C: Password S: Ok. C: Command S: answer C: Command S: answer ... C: bye S: <close> The difference between synchronous/asynchronous opperatons does not make much sense. Of course, in both operations there is allways the risk that the program flow stops indefinitely by some circunstance -there the use of timers-, but I would like know some more authorized opinions in this matter. I must admit that the question is rather ill-defined, but I like hear some advices about when use one or other, because I've problems in debugging with MS Visual Studio, asynchronous SSL operations in a POP3 client in wich I'm working now -about some of who surely I would write here soon-, and sometimes think that perhaps is a bad idea use asynchronous in this. Not to say that I'm an absolute newbie with this librarys, that additionally to the difficult with the idioma, and some obscure concepts in the STL, must suffer the brevity of the asio documentation.
