  • How do I add IIS Virtual Directories and arbitrary files in TFS Solution

    - by chriscena
    We have a web portal product from which we customize portals from customers. We use the precompiled web app and create a virtual directory (vd) where the customization resides. In addition to this we do some changes web.config in the web app folder. We would obviously like to keep these customizations under TFS source control. When I try to add the precompiled web app (which I don't want to add to source control), a warning tells me that the vds cannot be added. If I only add the folder that is referenced to by the vd, I lose the references to assemblies in the precompiled web app. My questions are: How do I structure a solution for adding IIS (sub application level) virtual directories and still retain the references to assemblies? Is it possible to add other directories/files from the web application level (like App_Theme, web.config etc.) to the solution? Since we already use Visual Source Safe, we have established a tree structure for each customization project: Project Root | |-Custom Sql | |-Custom Portal Files (which is added as a virtual directory) | |-Other Customizations I could probably do a lot of this manually through the source control explorer, but I'd like to have everything done through a solution. I've followed the instructions using this article: http://msdn.microsoft.com/en-us/library/bb668986.aspx, but this doesn't address the exact problem that I have. Oh, and we are currently using Visual Source Safe for portal customizaton, but are eager to make the move to TFS. TIA

  • Only last row in method execute (Objective-C)

    - by Emil
    First I want to apologize for my lack of knowledge in programming in general. I am in the way of learning and have discovered that this site is a huge compliment for me of doing so. I have created a program with three UITextField(thePlace,theVerb,theOutput) and two UITextView where one of the textviews(theOutput) take the text from the other textview(theTemplate) and replaces some strings with the text entered in the textfields. When I click a button it triggers the method createStory that is listed below. This works fine with one exception. The text in the output only changes the string 'number' to the text in the textfield. However if I change the order in the method to replace 'place','number','verb' only the verb is changed, not the number. Im sure this is some sort of easy fix but I can't find it. Can some of you help me with my troubleshooting? - (IBAction)createStory:(id)sender { theOutput.text=[theTemplate.text stringByReplacingOccurrencesOfString:@"<place>" withString:thePlace.text]; theOutput.text=[theTemplate.text stringByReplacingOccurrencesOfString:@"<verb>" withString:theVerb.text]; theOutput.text=[theTemplate.text stringByReplacingOccurrencesOfString:@"<number>" withString:theNumber.text]; } Many thanks // Emil

  • Native ComboBox not displaying choices correctly

    - by anothershrubery
    EDIT: It seems that ListPicker is the way to go but I have had further problems with that detailed Microsoft.Phone.Controls.Toolkit ListPicker throws XamlParseException I have the following ComboBox in code: <ComboBox x:Name="Result" Grid.Column="6" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="Black" Background="White"> <ComboBoxItem Content="Win" /> <ComboBoxItem Content="Place" /> <ComboBoxItem Content="Lose" /> </ComboBox> But it does not display as I would have expected. When you drop down the ComboBox the options don't appear, it's just like empty items. See below: However, when an item is selected, it displays correctly and the correct index/item is returned. See below: I'm sure there is something simple I have missed but can't put my finger on it. EDIT: Ok I am posting the full code for this.

  • Flex AS3: ComboBox set visible to false doesn't hide

    - by jolierouge
    I have a combobox in a view that receives information about application state changes, and then is supposed to show or hide it's children based on the whole application state. It receives state change messages, it traces the correct values, it does what it's supposed to do, however, it just doesn't seem to work. Essentially, all it needs to do is hide a combobox during one state, and show it again during another state. Here is the code: public function updateState(event:* = null):void { trace("Project Panel Updating State"); switch(ApplicationData.getSelf().currentState) { case 'login': this.visible = false; break; case 'grid': this.visible = true; listProjects.includeInLayout = false; listProjects.visible = false; trace("ListProjects: " + listProjects.visible); listLang.visible = true; break; default: break; } } Here is the MXML: <mx:HBox> <mx:Button id="btnLoad" x="422" y="84" label="Load" enabled="true" click="loadProject();"/> <mx:ComboBox id="listProjects" x="652" y="85" editable="true" change="listChange()" color="#050CA8" fontFamily="Arial" /> <mx:Label x="480" y="86" text="Language:" id="label3" fontFamily="Arial" /> <mx:ComboBox id="listLang" x="537" y="84" editable="true" dataProvider="{langList}" color="#050CA8" fontFamily="Arial" width="107" change="listLangChange(event)"/> <mx:CheckBox x="830" y="84" label="Languages in English" id="langCheckbox" click='toggleLang()'/> </mx:HBox>

  • Renaming TurboGears 2's Repoze Fields with TGAdmin

    - by William Chambers
    I've been working on renaming TurboGears 2's Repoze 'groups' field to 'roles' to free the namespace and db tables for other purposes. Also roles makes much more sense to me then groups because I have a strong Drupal background. Now I have found some of the docs to do this such as these: http://www.turbogears.org/2.1/docs/main/Auth/Customization.html#customizing-the-model-structure-assumed-by-the-quickstart http://code.gustavonarea.net/repoze.what-quickstart/#customizing-the-model-definition However these only go part of the way. I have made (I'm pretty sure at least, I've double checked a few times.) all the changes required as you can see in this diff. This seems to work fine however I've ran into a rather major issue with the TurboGears Admin system. I've tried http://turbogears.org/2.0/docs/main/Extensions/Admin/index.html and it didn't seem to make any difference, however I'm not 100% sure I did it correctly. The problem occurs when I attempt to go to localhost/admin/permissions/. It causes a Internal Server Error and outputs the following error. http://pastebin.com/YWMH3SiU This error does not happen on the Roles/Users pages and the permissions /edit/1 also works. I'm running kubuntu 10.04 with TG 2.1b2. (I'm running the beta mostly for easier mako support which is really important.) Any help would be very appreciated.

  • Checkbox does not change when clicked directly on it

    - by Matt McCormick
    I have a table of data and have one checkbox per row for the user to select the item. I'm using the following jQuery code to allow the user to select the item by clicking anywhere in the row: $("tbody tr").click(function() { var checkbox = $(this).find(':checkbox'); checkbox.attr('checked', !checkbox.attr('checked')); }); The problem is if I click directly on the checkbox, nothing happens. ie. if the checkbox is not checked, it remains unchecked. If I click anywhere else in the row, the checkbox changes status. I'm thinking that the jQuery code is causing the action to be performed twice. If I click on the checkbox, the checkbox will change but then the jQuery code for clicking on the row will be performed and the checkbox will be changed back. Not sure if that is actually happening but that is my guess. How can I get a checkbox to be toggled when a user clicks on a row and the same thing if they click directly on the checkbox?

  • C#.NET DataGridView - update database

    - by Geo Ego
    I know this is a basic function of the DataGridView, but for some reason, I just can't get it to work. I just want the DataGridView on my Windows form to submit any changes made to it to the database when the user clicks the "Save" button. On form load, I populate the DataGridView and that's working fine. In my save function, I basically have the following (I've trimmed out some of the code around it to get to the point): using (SqlDataAdapter ruleTableDA = new SqlDataAdapter("SELECT rule.fldFluteType AS [Flute], rule.fldKnife AS [Knife], rule.fldScore AS [Score], rule.fldLowKnife AS [Low Knife], rule.fldMatrixScore AS [Matrix Score], rule.fldMatrix AS [Matrix] FROM dbo.tblRuleTypes rule WHERE rule.fldMachine_ID = '1003'", con)) { SqlCommandBuilder commandBuilder = new SqlCommandBuilder(ruleTableDA); DataTable dt = new DataTable(); dt = RuleTable.DataSource as DataTable; ruleTableDA.Fill(dt); ruleTableDA.Update(dt); } Okay, so I edited the code to do the following: build the commands, create a DataTable based on the DataGridView (RuleTable), fill the DataAdapter with the DataTable, and update the database. Now ruleTableDA.Update(dt) is throwing the exception "Concurrency violation: the UpdateCommand affected 0 of the expected 1 records." Thanks very much!

  • How do I Extend Blogengine.Net to collect statistics of visitors?

    - by Stefan
    I love BlogEngine. But from what I can se it does not collect the standard information about the visitors I would like to see (referrer, browser-type and so on). When I log in as Admin I have a menu item named "Referrer". I can choose a weekday and then I'll be presented with 1 or 2 rows with "google.com 4 hits, "itmaskinen.se 6 hits" and so on, But that's not what I want to se, I want to se where my visitors come from, country, IP if possible, how many visitors and so on. If someone of you are familiar with Blogengine.Net and can point me in the right direction to where I would put my own log-code or if you know any visitor-statistic-extension that can do it for me, I would be really happy to know. I prefer an extension, because if I make changes myself to BlogEngine it may break later updates I install. Blogengine.Net is a blog software made in .Net found here: http://www.dotnetblogengine.net/ And yes, I prefer to take this question here rather then in the Blogengine.Net forum, you know why. ;) (Anyone, feel free to edit my (bad) english in this post and after that delete this sentence)

  • Storing an object to use in multiple classes

    - by Aaron Sanders
    I am wondering the best way to store an object in memory that is used in a lot of classes throughout an application. Let me set up my problem for you: We have multiple databases, 1 per customer. We also have a master table and each row is detailed information about the databases such as database name, server IP it's located and a few config settings. I have an application that loops through those multiple databases and runs some updates on them. The settings I mentioned above are updated each loop iteration into memory. The application then runs through series of processes that include multiple classes using this data. The data never changes during the processes, only during the loop iteration. The variables are related to a customer, so I have them stored in a customer class. I suppose I could make all of the members shared or should I use a singleton for the customer class? I've never actually used a singleton, only read they are good in this type of situation. Are there better solutions to this type of scenario? Also, I could have plans for this application to be multithreaded later. Sorry if this is confusing. If you have questions, let me know and I will answer them. Thanks for your help.

  • Is there an MVVM-friendly way to swap views without value converters firing unnecessarily?

    - by DanM
    I thought what I was doing was right out of the Josh Smith MVVM handbook, but I seem to be having a lot of problems with value converters firing when no data in the view-model has changed. So, I have a ContentControl defined in XAML like this: <ContentControl Grid.Row="0" Content="{Binding CurrentViewModel}" /> The Window containing this ContentControl references a resource dictionary that looks something like this: <ResourceDictionary ...> <DataTemplate DataType="{x:Type lib_vm:SetupPanelViewModel}"> <lib_v:SetupPanel /> </DataTemplate> <DataTemplate DataType="{x:Type lib_vm:InstructionsPanelViewModel}"> <lib_v:InstructionsPanel /> </DataTemplate> </ResourceDictionary> So, basically, the two data templates specify which view to show with which view-model. This switches the views as expected whenever the CurrentViewModel property on my window's view-model changes, but it also seems to cause value converters on the views to fire even when no data has changed. It's a particular problem with IMultiValueConverter classes, because the values in the value array get set to DependencyProperty.UnsetValue, which causes exceptions unless I specifically check for that. But I'm getting other weird side effects too. This has me wondering if I shouldn't just do everything manually, like this: Instantiate each view. Set the DataContext of each view to the appropriate view-model. Give the ContentControl a name and make it public. Handle the PropertyChanged event for the window. In the event handler, manually set the Content property of the ContentControl to the appropriate view, based the CurrentViewModel (using if statements). This seems to work, but it also seems very inelegant. I'm hoping there's a better way. Could you please advise me the best way to handle view switching so that value converters don't fire unnecessarily?

  • what libraries or platforms should I use to build web apps that provide real-time, asynchronous data

    - by Daniel Sterling
    This is a less a question with a simple, practical answer and more a question to foster discussion on the real-time data exchange topic. I'll begin with an example: Google Wave is, at its core, a real-time asynchronous data synchronization engine. Wave supports (or plans to support) concurrent (real-time) document collaboration, disconnected (offline) document editing, conflict resolution, document history and playback with attribution, and server federation. A core part of Wave is the Operational Transformation engine: http://www.waveprotocol.org/whitepapers/operational-transform The OT engine manages document state. Changes between clients are merged and each client has a sane and consistent view of the document at all times; the final document is eventually consistent between all connected clients. My question is: is this system abstract or general enough to be used as a library or generic framework upon which to build web apps that synchronize real-time, asynchronous state in each client? Is the Wave protocol directly used by any current web applications (besides Google's client)? Would it make sense to directly use it for generic state synchronization in a web app? What other existing libraries or frameworks would you consider using when building such a web app? How much code in such an app might be domain-specific logic vs generic state synchronization logic? Or, put another way, how leaky might the state synchronization abstractions be? Comments and discussion welcomed!

  • Define a swig interface file for generation of wrapper to every type from some header file

    - by Dmitriy Matveev
    Hi! We're using some C library in our Java project. Several years ago some other developer which has retired few years ago (as always) has created all the wrappers for us. The wrappers were generated by the swig, but the interface file is lost now. The basic idea of library and the wrappers for it is following: There only one function which returns pointer to some complex object. And there are wrapper for that function. The complex object is a tree-like structure with dozens of node kinds and types (C structures) used to represent them. There are hundreds of wrappers for every field of every type and we're trying to use them all. The library was updated some time ago and now there are some new data we unaware of which yet, but would like to use. This data is contained in some of the objects indirectly contained or referenced from the object created by the function we call (Some new fields and types were added). I know that I shouldn't make any changes to the wrappers by hand and should rather modify the interface, but as I already wrote it's missing. For now I only want to generate wrappers some few types which are added/changed and them to our old wrappers, but later I want to start creation of interface file which will define "what and how should be wrapped". All the definitions necessary for us are defined in single header file. Is it possible to tell swig to generate wrappers for every type in this header? If so, how can I write such interface file?

  • Modelling problem - Networked devices with commands

    - by Schneider
    I encountered a head scratching modelling problem today: We are modelling a physical control system composed of Devices and NetworkDevices. Any example of a Device is a TV. An example of a NetworkDevice is an IR transceiver with Ethernet connection. As you can see, to be able to control the TV over the internet we must connect the Device to the NetworkDevice. There is a one to many relationship between Device and NetworkDevice i.e. TV only has one NetworkDevice (the IR transceiver), but the IR transceiver may control many Devices (e.g. many TVs). So far no problem. The complicated bit is that every Device has a collection of Commands. The type of the Command (e.g IrCommand, SerialCommand - N.B. not currently modelled) depends on the type of NetworkDevice that the Device is connected to. In the current legacy system the Device has a collection of generic Commands (no typing) where fields are "interpreted" depending on the NetworkDevice type. How do I go about modelling this in OOP such that: You can only ever add a Command of the appropriate type, given the NetworkDevice the Device is attached to? If I change the NetworkDevice the Commands collection changes to the appropriate type Make it so the API is simple/elegant/intuitive to use

  • Eclipse won't believe I have Maven 2.2.1

    - by Andrew Clegg
    I have a project (built from an AppFuse template) that requires Maven 2.2.1. So I upgraded to this (from 2.1.0) and set my path and my M2_HOME and MAVEN_HOME env variables. Then I ran mvn eclipse:eclipse and imported the project into Eclipse (Galileo). However, in the problems list for the project (and at the top of the pom.xml GUI editor) it says: Unable to build project '/export/people/clegg/data/GanymedeWorkspace/funcserve/pom.xml; it requires Maven version 2.2.1 (Please ignore 'GanymedeWorkspace', I really am using Galileo!) This persists whether I set Eclipse to use its Embedded Maven implementation, or the external 2.2.1 installation, in the Preferences - Maven - Installations dialog. I've tried closing and reopening the project, reindexing the repository, cleaning the project, restarting the IDE, logging out and back in again, everything I can think of! But Eclipse still won't believe I have Maven 2.2.1. I just did a plugin update so I have the latest version of Maven Integration for Eclipse -- 0.9.8.200905041414. Does anyone know how to convince Eclipse I really do have the right version of Maven? It's like it's recorded the previous version somewhere else and won't pay any attention to my changes :-( Many thanks! Andrew.

  • Windows Form user control hosted in WPF - How to capture the leave event?

    - by OKB
    Hi, In my WPF application I'm hosting a custom Windows Form User Control together with other wpf controls. My custom user control is hosted in wpf using a WindowsFormsHost control. This custom user control contains (the parent so to speak) other custom win form controls (children controls). The children controls can be single or composite controls. How can I capture the leave event on a child control when the user navigates from the last child user control in the parent custom user control to a wpf user control? According to MSDN (http://msdn.microsoft.com/en-us/library/ms751797.aspx) the leave event is not supported in following scenarios: Enter and Leave events are not raised when the following focus changes occur: 1. From inside to outside a WindowsFormsHost control. 2. From outside to inside a WindowsFormsHost control. 3. Outside a WindowsFormsHost control. 4. From a Windows Forms control hosted in a WindowsFormsHost control to an ElementHost control hosted inside the same WindowsFormsHost. Scenario 1 and 2 is exactly what I struggle with. Do you have any solution to this problem? Some workaround or anything is appreciated:) Best Regards, OKB

  • Password Confirmation Overlay

    - by Alasdair
    Hello, I'm creating a J2EE web application that uses jQuery and Ajax to help with some of the presentation for a user-friendly interface. I've done a lot of work ensuring security around persistant login cookies, and I've decided to request the password from any user that logged in using a persistant login cookie before being allowed to make any changes that could be malicious. This request would only happen once to confirm the user is who they say they are and will last throughout the session. At present, any requests that meet this criteria has their request information stored in session and then the user is forwarded to a page to confirm their password. Once confirmed, the user's original request is then performed and the requestion information removed from session. What I would like to do is avoid all this redirection and minimize what's held in session (even if it's just for a small time), thus improving usability and convenience for the user. I believe that a jQuery overlay could allow me to prompt the user for their password (if required) and then continue to submit the request if successful. I would of originally used ThickBox, but since that's now deprecated I don't see the benefit in implementing it in an application at this development stage. However, I have tried to create an overlay using jQuery but I've scrapped every attempt as I can't seem to make it all come together. My main problem is preventing the submission when the user incorrectly types a password or cancels the overlay. Desired Flow Persistant Login Sensitive Page Submit Password Confirmation Overlay [Continue Submit | (Cancel | Incorrect] I have already created JavaScript code to encrypt the password to be sent in a parameter, but all I need now is a method of controlling the overlay and how best to use Ajax for this purpose. Please ignore the fact that this is a J2EE web application when answering as it is irrelevant really. Thanks in advance, Alasdair

  • web design question (php/ajax)

    - by tom smith
    Hi guys... Hope this isn't a waste of your time. I'm working on a project, and it occured to me that there's a chunk of code out there, that should allow me to see how others have implemented this. I've got a project where I'm going to have a page, with a sel box. the user will select an item from the selList, and based on the item selected, a separate section of the page (areaB) will change in terms of the content/tbls being displayed. i then want to allow the user to go through a series of subpages in areaB, where the user goes through a submit/cancel/confirm process, where the stuff in areaB changes, with the rest of the page remaining the same... i'm trying to figure out the best approach to implement the on both client/server side. i could just have an ugly "if block" where i have abunch of logic, and i completely regen the page each time the user selects an action.. i could have an approach that might involve divs/frames, where i then just regen the targeted frame/div area.. is this even possible?? i could have some form of ajaxy process, which would only alter the targeted section(s) of the page... so.. i'm trying to talk to anyone who has ideas on how to do this, or more ideally, if you know of a good code (client/server) side example of this... that i can examine. i'd really appreciate it!! i've got a more detailed overview but didn't know if it would be cool to post it here... thanks.. tom

  • how to push a string address to stack with assembly, machine code

    - by Yigit
    Hi all, I am changing minesweeper.exe in order to have an understanding of how code injection works. Simply, I want the minesweeper to show a message box before starting. So, I find a "cave" in the executable and then define the string to show in messagebox and call the messagebox. Additionally of course, I have to change the value at module entry point of the executable and first direct it to my additional code, then continue its own code. So at the cave what I do; "hello starbuck",0 push 0 //arg4 of MessageBoxW function push the address of my string //arg3, must be title push the address of my string //arg2, must be the message push 0 //arg1 call MessageBoxW ... Now since the memory addresses of codes in the executable change everytime it is loaded in the memory, for calling the MessageBoxW function, I give the offset of the address where MessageBoxW is defined in Import Address Table. For instance, if MessageBoxW is defined at address1 in the IAT and the instruction just after call MessageBoxW is at address2 instead of writing call MessageBoxW, I write call address2 - address1. So my question is, how do I do it for pushing the string's address to the stack? For example, if I do these changes via ollydbg, I give the immediate address of "hello starbuck" for pushing and it works. But after reloading the executable or starting it outside of ollydbg, it naturally fails, since the immediate addresses change. Thanks in advance, Yigit.

  • Weird behaviour of C++ destructors

    - by Vilx-
    #include <iostream> #include <vector> using namespace std; int main() { vector< vector<int> > dp(50000, vector<int>(4, -1)); cout << dp.size(); } This tiny program takes a split second to execute when simply run from the command line. But when run in a debugger, it takes over 8 seconds. Pausing the debugger reveals that it is in the middle of destroying all those vectors. WTF? Note - Visual Studio 2008 SP1, Core 2 Duo 6700 CPU with 2GB of RAM. Added: To clarify, no, I'm not confusing Debug and Release builds. These results are on one and the same .exe, without even any recompiling inbetween. In fact, switching between Debug and Release builds changes nothing.

  • PostgreSQL - Error: SQL state: XX000.

    - by rob
    I have a table in Postgres that looks like this: CREATE TABLE "Population" ( "Id" bigint NOT NULL DEFAULT nextval('"population_Id_seq"'::regclass), "Name" character varying(255) NOT NULL, "Description" character varying(1024), "IsVisible" boolean NOT NULL CONSTRAINT "pk_Population" PRIMARY KEY ("Id") ) WITH ( OIDS=FALSE ); And a select function that looks like this: CREATE OR REPLACE FUNCTION "Population_SelectAll"() RETURNS SETOF "Population" AS $BODY$select "Id", "Name", "Description", "IsVisible" from "Population"; $BODY$ LANGUAGE 'sql' STABLE COST 100 Calling the select function returns all the rows in the table as expected. I have a need to add a couple of columns to the table (both of which are foreign keys to other tables in the database). This gives me a new table def as follows: CREATE TABLE "Population" ( "Id" bigint NOT NULL DEFAULT nextval('"population_Id_seq"'::regclass), "Name" character varying(255) NOT NULL, "Description" character varying(1024), "IsVisible" boolean NOT NULL, "DefaultSpeciesId" bigint NOT NULL, "DefaultEcotypeId" bigint NOT NULL, CONSTRAINT "pk_Population" PRIMARY KEY ("Id"), CONSTRAINT "fk_Population_DefaultEcotypeId" FOREIGN KEY ("DefaultEcotypeId") REFERENCES "Ecotype" ("Id") MATCH SIMPLE ON UPDATE NO ACTION ON DELETE NO ACTION, CONSTRAINT "fk_Population_DefaultSpeciesId" FOREIGN KEY ("DefaultSpeciesId") REFERENCES "Species" ("Id") MATCH SIMPLE ON UPDATE NO ACTION ON DELETE NO ACTION ) WITH ( OIDS=FALSE ); and function: CREATE OR REPLACE FUNCTION "Population_SelectAll"() RETURNS SETOF "Population" AS $BODY$select "Id", "Name", "Description", "IsVisible", "DefaultSpeciesId", "DefaultEcotypeId" from "Population"; $BODY$ LANGUAGE 'sql' STABLE COST 100 ROWS 1000; Calling the function after these changes results in the following error message: ERROR: could not find attribute 11 in subquery targetlist SQL state: XX000 What is causing this error and how do I fix it? I have tried to drop and recreate the columns and function - but the same error occurs. Platform is PostgreSQL 8.4 running on Windows Server. Thanks.

  • Reasonable expectation to support new Operating Systems?

    - by Neil N
    My company has a desktop app originally developed for Windows XP. The original programmer has since been fired (fired with extreme prejudice I might add). I have fixed the app various times but overall try to avoid it, it is a mess and the only real way to fix it is to completely rewrite it, which could take a year. We have been trying to "forget" about this app, and instead steer clients towards our web version, which is more up to date, easier to maintain, easier to extend, and WAY easier to support. Most clients agree, the web version is just better all around. However we have one client that insists on using the desktop app. The app required a little duct tape to get working on Vista, but now completely breaks on Windows 7. I'm not even sure WHAT all the fixes are to get it working on Win7 (the current time estimate stands at "miracle") but after both installing the RELEASE build, and running the DEBUG build from Visual Studio, the app has errors on nearly every user action, and from what I can see from a high level test run, none of them are related. Since Windows 7 did not exist when this app was developed, is my company really expected to make all the required changes to make it function as "smoothly" as it did on XP?

  • segfault during __cxa_allocate_exception in SWIG wrapped library

    - by lefticus
    While developing a SWIG wrapped C++ library for Ruby, we came across an unexplained crash during exception handling inside the C++ code. I'm not sure of the specific circumstances to recreate the issue, but it happened first during a call to std::uncaught_exception, then after a some code changes, moved to __cxa_allocate_exception during exception construction. Neither GDB nor valgrind provided any insight into the cause of the crash. I've found several references to similar problems, including: http://wiki.fifengine.de/Segfault_in_cxa_allocate_exception http://forums.fifengine.de/index.php?topic=30.0 http://code.google.com/p/osgswig/issues/detail?id=17 https://bugs.launchpad.net/ubuntu/+source/libavg/+bug/241808 The overriding theme seems to be a combination of circumstances: A C application is linked to more than one C++ library More than one version of libstdc++ was used during compilation Generally the second version of C++ used comes from a binary-only implementation of libGL The problem does not occur when linking your library with a C++ application, only with a C application The "solution" is to explicitly link your library with libstdc++ and possibly also with libGL, forcing the order of linking. After trying many combinations with my code, the only solution that I found that works is the LD_PRELOAD="libGL.so libstdc++.so.6" ruby scriptname option. That is, none of the compile-time linking solutions made any difference. My understanding of the issue is that the C++ runtime is not being properly initialized. By forcing the order of linking you bootstrap the initialization process and it works. The problem occurs only with C applications calling C++ libraries because the C application is not itself linking to libstdc++ and is not initializing the C++ runtime. Because using SWIG (or boost::python) is a common way of calling a C++ library from a C application, that is why SWIG often comes up when researching the problem. Is anyone out there able to give more insight into this problem? Is there an actual solution or do only workarounds exist? Thanks.

  • How to get TinyMCE and Jquery validate to work together?

    - by chobo2
    Hi I am using jquery validate and the jquery version of tinymce. I found this piece of code that makes tinymce to validate itself every time something changes in it. Hi I am using the jquery validate with my jquery tinymce so I have this in my code // update validation status on change onchange_callback: function (editor) { tinyMCE.triggerSave(); $("#" + editor.id).valid(); }, This works however there is one problem. If a user copies something from word it brings all that junk styling with it what is usually over 50,000 characters. This is way over my amount of characters a user is allowed to type in. So my jquery validation method goes off telling me that they went over the limit. In the mean time though tinymce has cleaned up that mess and it could be possible now the user has not gone over the limit. Yet the message is still there. So is there a better function call I can put this in? Maybe tell tinymce to delay the valid when a paste is happening, or maybe a different callback? Anyone got any ideas?

  • C#+BDE+DBF problem

    - by Drabuna
    I have huge problem: I have lots of .dbf files(~50000) and I need to import them into Oracle database. I open conncection like this: OleDbConnection oConn = new OleDbConnection(); OleDbCommand oCmd = new OleDbCommand(); oConn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + directory + ";Extended Properties=dBASE IV;User ID=Admin;Password="; oCmd.Connection = oConn; oCmd.CommandText = @"SELECT * FROM " + tablename; try { oConn.Open(); resultTable.Load(oCmd.ExecuteReader()); } catch (Exception ex) { MessageBox.Show(ex.Message); } oConn.Close(); oCmd.Dispose(); oConn.Dispose(); I read them in loop, and then insert into oracle. Everything's fine. BUT: There is about 1000 files, that I can't open. They raise exception "not a table". So I google, and install Borland Database Engine. Now everything wokrs fine....but no. Now, when I'm reading files, on 1024 file exception raises: "System resource exceeded". But I have lots of free resources. When I remove BDE, everything's fine again, no "system resource exceeded" error, but I cant read all files. Help please. PS: Tried using ODBC but nothing changes.
