  • How to make Python Extensions for Windows for absolute beginners

    - by JR
    Hello: I've been looking around the internet trying to find a good step by step guide to extend Python in Windows, and I haven't been able to find something for my skill level. let's say you have some c code that looks like this: #include <stdio.h> #include <math.h> double valuex(float value, double rate, double timex) { float value; double rate, timex; return value / double pow ((1 + rate), (timex)); } and you want to turn that into a Python 3 module for use on a windows (64bit if that makes a difference) system. How would you go about doing that? I've looked up SWIG and Pyrex and in both circumstances they seem geared towards the unix user. With Pyrex I am not sure if it works with Python 3. I'm just trying to learn the basics of programing, using some practical examples. Lastly, if there is a good book that someone can recommend for learning to extend, I would greatly appreciate it. Thank you.

  • Switching from ListView to VirtualStringTree

    - by Jeff
    Hey S.O! I am trying to build my projects with a VirtualStringTree rather than a Listview, because of the vast speed difference. The thing is, even after looking thru the demo's, I just can't figure out exactly how I would use it as a ListView. Like, adding, deleting, and basically just working with ListView items is so easy, but when I look at the VT, it gets almost too complicated. All I am looking for, is a VT that looks like a ListView, with subitems etc. Here are some routines using the ListView, that I would like to use with VT (This is just a pseudo example: procedure Add; begin with ListView.Items.Add do Begin Caption := EditCaption.Text; SubItems.Add(EditSubItem.Text): End; end; Procedure ReadItem(I : Integer); begin ShowMessage(ListView.Items[I].Caption); ShowMessage(ListView.Items[I].SubItems[0]); end; Of course, also the Delete function, but since thats like 1 line, I didnt bother :P Could anyone maybe translate the above examples into using a ListView style VT? Thanks!

  • Client WCF DataContract has empty/null values from service

    - by Matt
    I have a simple WCF service that returns the time from the server. I've confirmed that data is being sent by checking with Fiddler. Here's the result object xml that my service sends. <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> <s:Body> <GetTimeResponse xmlns="http://tempuri.org/"> <GetTimeResult xmlns:a="http://schemas.datacontract.org/2004/07/TestService.DataObjects" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> <a:theTime>2010-03-26T09:14:38.066372-06:00</a:theTime> </GetTimeResult> </GetTimeResponse> </s:Body> </s:Envelope> So, as far as I can tell, there's nothing wrong on the server end. It's receiving requests and returning results. But on my silverlight client, all the members of the returned object are either null, blank or a default vaule. As you can see the server returns the current date and time. But in silverlight, theTime property on my object is set to 1/1/0001 12:00 AM (default value). Sooo methinks that the DataContracts do not match up between the server and the silverlight client. Here's the DataContract for the server [DataContract] public class Time { [DataMember] public DateTime theTime { get; set; } } Incredibly simple. And here's the datacontract on my silverlight client. [DataContract] public class Time { [DataMember] public DateTime theTime { get; set; } } Literally the only difference is the namespaces within the application. But still the values being returned are null, empty or a .NET default. Thanks for you help!

  • WCF NetTcpBinding Security - how does it work?

    - by RemotecUk
    Hi, encountered the following problems trying to work through the quagmire of settings in WCF... I created a WCF client server service using a NetTcp binding. I didn't make any changes to the security settings and when running on one machine it works very nicely. However, when I ran my client from another machine it complained that the server didnt like the security credentials that were sent. I understand now that NetTCP is "secured" by default and that my client would have been passing the wrong security details - namely the windows user name and password (or some form of domain authentication) to my server which as they are not running on the same domain it would not have liked. However, what I don't understand is as follows: I haven't specified any security in my binding - does the standard settings expect a windows user name or password to be sent? I don't have any certificate installed on my server - I understand that NetTCP bindings need some form of public private key to protect the credentials - yet this seemed to work when both client and server were on the same machine - how was the data getting encrypted? Or wants it as WCF knew it was on the same machine and encryption isn't needed? I have had to set my security mode on my client and server to "none" now and they connect nicely. However is there any way to encrypt my data without a certificate? Finally... what is the difference between Transport and Message security? To check my understanding (excuse the scenario!) message security is like if I sent a letter from person A to person B and I encode my hand writing to ensure that if anyone intercepts it they cannot read it? Transport Security is if I decide to have my letter sent by armed transport so that no one can get at it along the way? Is it possible to have any form of encryption in WCF without a certificate? My project is a private project and I dont want to purchase a certificate and the data isnt that sensitive anyway so its just for my own knowledge. Thanks in advance.

  • Codeigniter + TankAuth + Swfupload not able to get the logger user id

    - by Manny Calavera
    Hello. I am using Codeigniter with the TankAuth library installed and trying to upload to index.php/reuqests/doUpload from swfupload but can't access the page as authenticated. I have read many posts around the net about similar problem and tried to set $config['sess_match_useragent'] = FALSE; but still no difference. I have ended up skipping the login check in my controller for testing purposes. But now I need to access tankAuth library from my controller to get the current logged in user ID. It is requested in my application and cannot skip it, I really need to pass the logged in user id to that doUpload model. I have setup controller like this: function doUploadFileFn() { if (!$this->tank_auth->is_logged_in()) { return; } else { $user_id = $this->tank_auth->get_user_id(); $this->load->model('requests/doUploadFile'); $this->doUploadFile->uploadData($user_id); } } Now, it does not pass the is_logged_in() check, as I learned from other posts, CI deletes the session but I have setup the config not to match the user agent but still not working. Is there any solution to this out there ? Thank you.

  • CodeIgniter/PHP - Calling a view from within a view

    - by Jack W-H
    Hi Folks Basically for my webapp I'm trying to organise it a bit better. As it at the moment, every time I want to load a page, I have to do it from my controller like so: $this->load->view('subviews/template/headerview'); $this->load->view('subviews/template/menuview'); $this->load->view('The-View-I-Want-To-Load'); $this->load->view('subviews/template/sidebar'); $this->load->view('subviews/template/footerview'); As you can tell it's not really very efficient. So I thought I'd create one 'master' view - It's called template.php. This is the contents of the template view: <?php $view = $data['view']; $this->load->view('subviews/template/headerview'); $this->load->view('subviews/template/menuview'); $this->load->view($view); $this->load->view('subviews/template/sidebar'); $this->load->view('subviews/template/footerview'); ?> And then I thought I'd be able to call it from a controller like this: $data['view'] = 'homecontent'; $this->load->view('template',$data); Unfortunately I simply cannot make this work. Does anyone have any ways around this or fixes I can put into place? I've tried putting ""s and ''s around $view in template.php but that makes no difference. The usual error is "Undefined variable: data" or "Cannot load view: $view.php" etc. Thanks folks! Jack

  • comparison between string literal

    - by wiso
    This very simple code: #include <iostream> using namespace std; void exec(char* option) { cout << "option is " << option << endl; if (option == "foo") cout << "option foo"; else if (option == "bar") cout << "opzion bar"; else cout << "???"; cout << endl; } int main() { char opt[] = "foo"; exec(opt); return 0; } generate two warning: comparison with string literal results in unspecified behaviour. Can you explain why exactly this code doesn't work, but if I change char opt[] to char *opt it works, but generates the warning? Is it related to the \0 termination? What is the difference between the two declaration of opt? What if I use const qualifier? The solution is to use std::string?

  • C++ smart pointers: sharing pointers vs. sharing data

    - by Eli Bendersky
    In this insightful article, one of the Qt programmers tries to explain the different kinds of smart pointers Qt implements. In the beginning, he makes a distinction between sharing data and sharing the pointers themselves: First, let’s get one thing straight: there’s a difference between sharing pointers and sharing data. When you share pointers, the value of the pointer and its lifetime is protected by the smart pointer class. In other words, the pointer is the invariant. However, the object that the pointer is pointing to is completely outside its control. We don’t know if the object is copiable or not, if it’s assignable or not. Now, sharing of data involves the smart pointer class knowing something about the data being shared. In fact, the whole point is that the data is being shared and we don’t care how. The fact that pointers are being used to share the data is irrelevant at this point. For example, you don’t really care how Qt tool classes are implicitly shared, do you? What matters to you is that they are shared (thus reducing memory consumption) and that they work as if they weren’t. Frankly, I just don't undersand this explanation. There was a clarification plea in the article comments, but I didn't find the author's explanation sufficient. If you do understand this, please explain. What is this distinction, and how are other shared pointer classes (i.e. from boost or the new C++ standards) fit into this taxonomy? Thanks in advance

  • Redirect from URL with QueryString to the same URL without QueryString

    - by Slauma
    I have a page request with a QueryString, say http://www.xyz.net/Orders.aspx?OrderID=1. The page is displayed in a browser. Now there is an asp:LinkButton on the page which should enable the user to open the page without the QueryString (as if he had entered http://www.xyz.net/Orders.aspx directly in the browser's address bar). I had two ideas: 1) Use the PostBackUrl attribute of the LinkButton: <asp:LinkButton ID="LinkButton1" runat="server" Text="Select" PostBackUrl="~/Orders.aspx" /> 2) Use "RedirectUrl" in an event handler: <asp:LinkButton ID="LinkButton1" runat="server" Text="Select" OnClick="LinkButton1_Click" /> ...and... protected void LinkButton1_Click(object sender, EventArgs e) { Response.Redirect("~/Orders.aspx"); } In both cases the browser's address bar shows http://www.xyz.net/Orders.aspx without the QueryString, as I like to have it. But in the first case the page does not change at all. But it should, because I'm evaluating the QueryString in code-behind and control the appearance of the page depending on whether a QueryString exists or not. The second option works as intended. If I am not wrong the second option requires an additional roundtrip: Browser sends request to server Event handler on server side sends Redirect URL to browser Browser sends again request to the server, but with the new URL Server sends new requested page to browser Is this correct at all? Whereas the first option omits the first two steps in the list above, thus saving the additional roundtrip and resulting in: Browser sends request to the server, but with the new URL (the PostbackURL specified in the LinkButton) Server sends new requested page to browser But, as said, the result isn't the same. I'm sure my try to explain the differences between the two options is wrong somewhere. But I don't know where exactly. Can someone explain what's really the difference? Do I really need this second roundtrip of option (2) to achieve what I want? Thanks in advance!

  • How to add a default value to a custom ASP.NET Profile property

    - by mr.moses
    I know you can add defaultValues using the web.config like this: <profile> <properties> <add name="AreCool" type="System.Boolean" defaultValue="False" /> </properties> </profile> but I have the Profile inherited from a class: <profile inherits="CustomProfile" defaultProvider="CustomProfileProvider" enabled="true"> <providers> <clear /> <add name="CustomProfileProvider" type="CustomProfileProvider" /> </providers> </profile> Heres the class: Public Class CustomProfile Inherits ProfileBase Public Property AreCool() As Boolean Get Return Me.GetPropertyValue("AreCool") End Get Set(ByVal value As Boolean) Me.SetPropertyValue("AreCool", value) End Set End Property End Class I don't know how to set the default value of the property. Its causing errors because without a default value, it uses an empty string, which cannot be converted to a Boolean. I tried adding <DefaultSettingValue("False")> _ but that didn't seem to make a difference. I'm also using a custom ProfileProvider (CustomProfileProvider).

  • DataTable.Select Behaves Strangely Using ISNULL Operator on NULL DateTime Column

    - by Paul Williams
    I have a DataTable with a DateTime column, "DateCol", that can be DBNull. The DataTable has one row in it with a NULL value in this column. I am trying to query rows that have either DBNull value in this column or a date that is greater than today's date. Today's date is 5/11/2010. I built a query to select the rows I want, but it did not work as expected. The query was: string query = "ISNULL(DateCol, '" + DateTime.MaxValue + "'") > "' + DateTime.Today "'" This results in the following query: "ISNULL(DateCol, '12/31/9999 11:59:59 PM') > '5/11/2010'" When I run this query, I get no results. It took me a while to figure out why. What follows is my investigation in the Visual Studio immediate window: > dt.Rows.Count 1 > dt.Rows[0]["DateCol"] {} > dt.Rows[0]["DateCol"] == DBNull.Value true > dt.Select("ISNULL(DateCol,'12/31/9999 11:59:59 PM') > '5/11/2010'").Length 0 <-- I expected 1 Trial and error showed a difference in the date checks at the following boundary: > dt.Select("ISNULL(DateCol, '12/31/9999 11:59:59 PM') > '2/1/2000'").Length 0 > dt.Select("ISNULL(DateCol, '12/31/9999 11:59:59 PM') > '1/31/2000'").Length 1 <-- this was the expected answer The query works fine if I wrap the DateTime field in # instead of quotes. > dt.Select("ISNULL(DateCol, #12/31/9999#) > #5/11/2010#").Length 1 My machine's regional settings is currently set to EN-US, and the short date format is M/d/yyyy. Why did the original query return the wrong results? Why would it work fine if the date was compared against 1/31/2000 but not against 2/1/2000?

  • VB.Net plugin using Matlab COM Automation Server...Error: 'Could not load Interop.MLApp'

    - by Ben
    My Problem: I am using Matlab COM Automation Server to call and execute matlab .m files from a VB.Net plugin for a CAD program called Rhino 3D. The code works flawlessly when set up as a simple Windows Application in Visual Studio, but when I insert it (and make the requisite reference) into my .Net plugin and test it in the CAD program I get the following error: "Could not load file or assembly 'Interop.MLApp, Version 1.0.0.0, culture=neutral, PublicKeyToken=null' or one of its dependencies. the system cannot find the file specified." What I've Tried: I am baffled as to why this occurs, but I was able to contact the CAD program's technical support staff and they suggested that it has something to do with their DotNet SDK having trouble with references that are located far outside the CAD program directory. They didn't have any solutions so I tried playing around with copylocal and this made no difference. I tried using other COM libraries and the Open Office automation server works fine, although uses url's instead of requiring a reference. I also tested Excel, which does require a reference, and it returned the error: "retrieving the COM class factory for component with CLSID {...} failed due to the following error: 80040154." This may or may not be related to the issue with the Matlab COM reference, but I thought was worthwhile to share. Perhaps is there another way to reference Interop.MLApp? I would appreciate any suggestions or thoughts on how I might make the Matlab Interop.MLApp reference work. Best regards, Ben

  • Time flies like an arrow demo in WinForms

    - by Benjol
    Looking at the Reactive Extensions for javascript demo on Jeff Van Gogh's blog, I thought I'd give it a try in C#/Winforms, but it doesn't seem to work so well. I just threw this into the constructor of a form (with the Rx framework installed and referenced): Observable.Context = SynchronizationContext.Current; var mousemove = Observable.FromEvent<MouseEventArgs>(this, "MouseMove"); var message = "Time flies like an arrow".ToCharArray(); for(int i = 0; i < message.Length; i++) { var l = new Label() { Text = message[i].ToString(), AutoSize = true, TextAlign = ContentAlignment.MiddleCenter }; int closure = i; mousemove .Delay(closure * 150) .Subscribe(e => { l.Left = e.EventArgs.X + closure * 15 + 10; l.Top = e.EventArgs.Y; //Debug.WriteLine(l.Text); }); Controls.Add(l); } When I move the mouse, the letters seem to get moved in a random order, and if I uncomment the Debug line, I see multiple events for the same letter... Any ideas? I've tried Throttle, but it doesn't seem to make any difference. Am I just asking too much of WinForms to move all those labels around? (Cross posted on Rx Forum)

  • Understanding the Silverlight Dispatcher

    - by Matt
    I had a Invalid Cross Thread access issue, but a little research and I managed to fix it by using the Dispatcher. Now in my app I have objects with lazy loading. I'd make an Async call using WCF and as usual I use the Dispatcher to update my objects DataContext, however it didn't work for this scenario. I did however find a solution here. Here's what I don't understand. In my UserControl I have code to call an Toggle method on my object. The call to this method is within a Dispatcher like so. Dispatcher.BeginInvoke( () => _CurrentPin.ToggleInfoPanel() ); As I mentioned before this was not enough to satisfy Silverlight. I had to make another Dispatcher call within my object. My object is NOT a UIElement, but a simple class that handles all its own loading/saving. So the problem was fixed by calling Deployment.Current.Dispatcher.BeginInvoke( () => dataContext.Detail = detail ); within my class. Why did I have to call the Dispatcher twice to achieve this? Shouldn't a high-level call be enough? Is there a difference between the Deployment.Current.Dispatcher and the Dispatcher in a UIElement?

  • The best way to package iPhone/iPad static libraries?

    - by Derek Clarkson
    Hi everyone, I have a couple of static Phone/iPad libraries I an working on. The problem I am looking for advise on is the best way to package the libraries. My objective is to make it easy to use the libraries in other projects and include the correct one in a build with minimal problems. To make it more interesting I currently build 4 versions of each library as follows armv6/armv7 release (devices) i386 release (simulator) armv6/armv7 debug (devices) i386 debug (simulator) The difference between the release and debug versions is that the debug versions contain a lot of NSLog(...) code which enables people to see whats going on internally as an aid to debugging. Currently when I build the whole projects I arrange the libraries into two directories like this: release lib-device.a lib-simulator.a debug lib-device.a lib-simulator.a This works ok except that when include in projects, both paths are added to the library search path and switching a target from one to the other is a pain. Or alternatively I end up with two targets. The alternative I am thinking of is to change the directories like this: release device lib.a simulator lib.a debug device lib.a simulator lib.a In playing with XCode is appears that all xcode uses the lbrary references of a project for is to get the name of the library file, which it then looks up in the library paths. Thus by parameterising the library path with the current built type and target device, I can effectively auto switch. What do you guys think? Is there a better way to do this? ciao Derek

  • VS2008 javascript debugger IE8 "there is no source code available for the current location"

    - by Jeff Keslinke
    I have almost the same problem as this unanswered question. The only difference is I'm using VS2008, but I'm in an MVC project calling this javascript function: function CompanyChange(compCtrl) { alert(compCtrl.value); debugger; var test; for (var i = 0; i < document.all.length; i++) { test = document.all[i]; } } I hit the alert, then I get the message "there is no source code available for the current location." At which point the page becomes unresponsive and I have to manually stop the debugger just to shut it down. I've logged into another machine and ran this exact code and it works fine, I hit the debugger and can step through. I've checked to make sure all settings in VSToolsOptionsDebugging are identical as well as IEOptionsAdvanced and they are. Both machines are Windows 7 Enterprise edition 32-bit, VS2008, IE8. I've also tried attaching a process manually in VS, and using the 'Developer Tools' in IE which didn't work (said there already was a process attached). I was hoping someone may have had this problem and found a work-around because I've already done a lot of searching and tried all the options I've read. Anyone else run into this? Thank you, Jeff

  • running asp.net 3.5 and asp.net 2.0 in same site

    - by cori
    We're running ASP.Net 2.0 on our corporate web site, and I'd like to get it up to ASP.Net 3.5 as smoothly as possible. The project/solution architecture in VS 2005 is an ASP.Net 2.0 web project and an .Net 2.0 data access layer project which is used by the site code. Upon opening the projects in a new VS 2008 solution they seemed to be converted to .Net 3.5 with a minimum of fuss - they built correctly out of the box, deployed successfully, and seem to work just fine, which is exactly as I would expect given that .Net 2.0 and 3.5 share a common runtime. The major difference after the conversion is that the web.config file's referenced dlls are now the 3.5 versions. What I would like to do is to update the site piecemeal; as I make modifications to a given page send the 3.5 verson of that page over to our webserver and not update the whole site at once. In testing on our dev box this approach seems to be working fine - the site code is interacting with the .Net 3.5 data access layer without difficulty, a handful of pages are running 3.5 page-behind code (by this I mean that they're running assemblies built in VS 2008 - the site is using single-page assemblies for code behind), the 3.5 web.config is in place, and the bulk of the site is running code-behind assemblies built in VS2005. Everything looks great. Which makes me worried that I'm missing something. Is this architecture workable, or is there a problem lying is wait for m that I haven't considered?

  • Kruskal-Wallis test with details on pairwise comparisons

    - by dalloliogm
    The standard stats::kruskal.test module allows to calculate the kruskal-wallis test on a dataset: >>> data(diamonds) >>> kruskal.test.test(price~carat, data=diamonds) Kruskal-Wallis rank sum test data: price by carat by color Kruskal-Wallis chi-squared = 50570.15, df = 272, p-value < 2.2e-16 this is correct, it is giving me a probability that all the groups in the data have the same mean. However, I would like to have the details for each pair comparison, like if diamonds of colors D and E have the same mean price, as some other softwares do (SPSS) when you ask for a Kruskal test. I have found kruskalmc from the package pgirmess which allows me to do what I want to do: > kruskalmc(diamonds$price, diamonds$color) Multiple comparison test after Kruskal-Wallis p.value: 0.05 Comparisons obs.dif critical.dif difference D-E 571.7459 747.4962 FALSE D-F 2237.4309 751.5684 TRUE D-G 2643.1778 726.9854 TRUE D-H 4539.4392 774.4809 TRUE D-I 6002.6286 862.0150 TRUE D-J 8077.2871 1061.7451 TRUE E-F 2809.1767 680.4144 TRUE E-G 3214.9237 653.1587 TRUE E-H 5111.1851 705.6410 TRUE E-I 6574.3744 800.7362 TRUE E-J 8649.0330 1012.6260 TRUE F-G 405.7470 657.8152 FALSE F-H 2302.0083 709.9533 TRUE F-I 3765.1977 804.5390 TRUE F-J 5839.8562 1015.6357 TRUE G-H 1896.2614 683.8760 TRUE G-I 3359.4507 781.6237 TRUE G-J 5434.1093 997.5813 TRUE H-I 1463.1894 825.9834 TRUE H-J 3537.8479 1032.7058 TRUE I-J 2074.6585 1099.8776 TRUE However, this package only allows for one categoric variable (e.g. I can't study the prices clustered by color and by carat, as I can do with kruskal.test), and I don't know anything about the pgirmess package, whether it is maintained or not, or if it is tested. Can you recommend me a package to execute the Kruskal-Wallis test which returns details for every comparison? How would you handle the problem?

  • Regarding: PKCS7, X509 and DER

    - by Sid
    Hi, I am novice to the "World of cryptography". I started working with OPENSSL. I need some information and basically I do have some doubts. I have a DER format file. I read the file using following command, "openssl x509 -inform DER -in filename.der -text" I got what I supposed to be. Following things I wanted to know: 1. What is the difference between PKCS7, DER and X509 ? (My understanding is, DER is format, X509 is certificate, and PKCS7 is the standard) I wrote a test file which accepts the DER file and outputs the version, serial number, Subject, Validity date before and Validity date after, But I am unable to get certificate verified. Following is the API Used. int i = X509_verify(X509 *x509 , X509_get_pubkey(X509 *x509)); But 'i' value is 'i' < 0(zero) This is why I am getting "Signature verification problems". How to overcome this? In My test file I am unable to read the "Signature Algorithm", "Subject Public Key Info", "X509v3 extensions" and "-----BEGIN CERTIFICATE-----" to "-----END CERTIFICATE-----" Please give some inputs. Thanks in Advance. openSid

  • HttpUtility does not exist in the current context

    - by Shaihi
    I get this error when compiling a C# application. Looks like a trivial error, but I can't get around it. My setup is Windows 7 64 bit. Visual-Studio 2010 C# express B2Rel. I added a reference to System.Web.dll located at C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0, but it has a yellow exclamation symbol and I still get the above error. I also have the using System.Web declaration. What am I doing wrong? Update: After getting the prompt answer pointing me at the root cause, I searched a bit in Google to where it states that System.Web.dll is for the full framework. I did not find such a reference. For newbies like me, this blog summarizes the difference between the frameworks (client and full) nicely. I could not find a spot that says whether a certain Dll is supported in the client framework or not. I guess the exclamation mark in Visual Studio should be the first signal...

  • ILOG CPLEX: how to populate IloLPMatrix while using addGe to set up the model?

    - by downer
    I have a queatoin about IloLPMatrix and addGe. I was trying to follow the example of AdMIPex5.java to generate user defined cutting planes based on the solution to the LP relaxation. The difference is that eh initial MIP model is not read in from a mps file, but set up in the code using methods like addGe, addLe etc. I think this is why I ran into problems while copying the exampe to do the following. IloLPMatrix lp = (IloLPMatrix)cplex.LPMatrixIterator().next(); lp from the above line turns to be NULL. I am wondering 1. What is the relationship between IloLPMatrix and the addLe, addGe commands? I tried to addLPMatrix() to the model, and then used model.addGe methods. but the LPMatrix seems to be empty still. How do I populate the IloLPMatrix of the moel according to the value that I had set up using addGe and addLe. Is the a method to this easily, or do I have to set them up row by row myself? I was doing this to get the number of variables and their values by doing lp.getNumVars(). Is there other methods that I can use to get the number of variables and their values wihout doing these, since my system is set up by addLe, addGe etc? Thanks a lot for your help on this.

  • jquery validate: focusCleanup: true and focusInvalid: false don't work as expected

    - by laramichaels
    I am using Joern's jquery validation plugin 1.6. My goal is to have the following behavior: remove the error message for an element once the user focuses it. From what I understand setting 'focusCleanup: true' should take care of this. However (at least on my browser (Firefox 3.5.7 on Linux)), I only get the desired behavior (ie, error message for a field disappearing once you focus it) if I click into the field; it doesn't handle tabbing into the field correctly. Sample code: HTML: <form id='abc' name='abc'> <input type="text" id="t1" name="t1"/> <input type="text" id="t2" name="t2"/> <input type="submit" id="submit" value='submit'/> </form> JS: $("#abc").validate({ focusCleanup: true, focusInvalid: false, rules: {t1: {required: true, email:true}, t2: {required: true,email:true}} }); I am setting 'focusInvalid: false' because the docs say one should avoid combining focusCleanup and focusInvalid; in my experience commenting out that line makes no difference. Am I doing something wrong?

  • "Unrecognized configuration section connectionStrings" in app.exe.config

    - by Richard Bysouth
    Hi On a Terminal Server install of my WinForms app, one of my clients gets the following exception on startup: "Unrecognized configuration section connectionStrings" This is occurring in myapp.exe.config but I can't figure out why. Runs perfectly everywhere else, only difference between this install and any other is the connection string. I've searched around, but can only find this issue relating to ASP.NET apps and issues in web.config. Any ideas what could be broken in the config of this WinForms app though? Is it indicating a problem further up in machine.config? FYI the top part of myapp.exe.config is: <?xml version="1.0" encoding="utf-8"?> <configuration> <configSections> <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=jjjjjjjjjj"> <section name="MyApp.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=jjjjjjjj" requirePermission="false" /> </sectionGroup> <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=jjjjjjjjj"> <section name="MyApp.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=jjjjjjjjjj" allowExeDefinition="MachineToLocalUser" requirePermission="false" /> </sectionGroup> </configSections> <connectionStrings> <add name="MyApp.DataAccessLayer.Settings.MyConnectionString" connectionString="$$$$$$" providerName="System.Data.SqlClient" /> </connectionStrings> ... thanks Richard

  • Hyphen vs Dash : Replace Dash with Hyphen

    - by soldieraman
    Alright so we had a problem recently In reporting services some of the String Columns were appearing as gibberish Chinese characters. On further investigation we found it is the hyphen. Well that's what we though first. On further investigation we found it a dash (or en dash) . Basically the reason this has happened is people copy pasting values into this column from word which converts hyphens into dashes automatically. But if you look at the database they both look the same. Though on the application side you can see the difference. How do I replace the dash with a normal hyphen. If you copy the value in put it in SQL server. A hyphen is gray while a dash is black but they both look exactly the same (i.e not bigger or smaller). Problem is I can't write a REPLACE script then (they are the freakin same) REPLACE ('-' with '-') is there a way special characters like the dash can be identified in SQL server? SQL Server v 2005
