• .NET COM Interop with references to other libraries

  - by user262190

  Hello,I'm up against a problem when loading a class in a managed library from a COM Interop library. basically I have some Unmanaged C++ code and a COM Interop library written in C#. And finally a 3rd library which is referenced by the COM Interop library which contains a class: public class MyClass{ public MyClass(){} } What I'd like to do is from my unmanaged c++ code, call a function in the Interop library The C++ code doesn't need to know of the existence of the third library, it's only used within the Interop. Init(){ MyClass _class = new MyClass(); } for some reason this line in Init fails "MyClass _class = new MyClass();", and I don't get very usefull error messages, all I have to go on is a few of these in my output window: "First-chance exception at 0x7c812afb in DotNet_Com_Call.exe: Microsoft C++ exception: [rethrow] at memory location 0x00000000.." and the HRESULT of the "HRESULT hr = pDotNetCOMPtr-Init();" line in my C++ code is "The system cannot find the specified file" I'm new to COM so if anyone has any ideas or pointer to get me going the right direction, I'd appreciate it, Thanks

• [cocoa] NSSearchField not working as expected

  - by Vegar

  Hi, I'm trying to follow Marcus Zarra in his book 'Core Data'. In the book, he makes a small sample application, but it doesn't give much help when things don't work out... He starts out by visually designing three entities, and then adding array controllers for each entity to the main nib. Second, he adds a tableview and some other visual components to show data from the array controllers. So far, I have managed to follow, but now he adds a search field to the gui, and binds it to the same array controller as one of the tableviews. Expected behavior would be for the tableview to get filtered when typing in the search field, but nothing happens. How do I find out what's wrong? The relevant parts from the nib is as follow: NSArrayController Recipes - Mode = Entity - Enitity Name = Recipe TableView w/TableColumn - Value Bind To Recipes -- Controller Key = arrangedObjects -- Model Key Path = name Search Field - Predicate Bind To Recipes -- Controller Key = filterPredicate -- Model Key Path = name -- Display name = predicate -- Predicate Format = keyPath contains $value There are no relevant messages in the console. regards, -Vegar

• Clear validation on textInput when validation is not enabled

  - by Jon

  Hi, I've created a custom textInput componenet that handles it's own validation using a private validator. The validation is enabled depending on the state of the component i.e. validation is enable when the components state is "edit". However, when the state changes from edit the internal validator is set to not enabled but the validation errors on the textbox do not clear - the textInput still has the red border and on mouseover the validation errors come up. What I want to happen is that when a validator is disabled the error formatting and error messages clear from the text input control. Does anyone have any idea how to do this I tried setting the internal validator instance to enabled = false and dispatching a new focusOutEvent as below but the validation error formatting is still applied to the textInput contrl. _validatorInstance.enabled = false; //clear the validation errors if any dispatchEvent(new FocusEvent(FocusEvent.FOCUS_OUT)); Any ideas? Thanks Jon

• How to programmatically open the application menu in a .NET CF 2.0 application

  - by PabloG

  I'm developing an C# / .NET CF 2.0 application: it's supposed to be used with the touchscreen deactivated, then, I'm looking for a way to programmatically open the application menu (not the Windows menu). Looking here I tried to adapt the code to the .NET CF 2 but it doesn't work (no error messages neither) public const int WM_SYSCOMMAND = 0x0112; public const int SC_KEYMENU = 0xF100; private void cmdMenu_Click(object sender, EventArgs e) { Message msg = Message.Create(this.Handle, WM_SYSCOMMAND, new IntPtr(SC_KEYMENU), IntPtr.Zero); MessageWindow.SendMessage(ref msg); } Any ideas? TIA, Pablo After Hans answer, I edited the code to Message msg = Message.Create(this.Handle, WM_SYSCOMMAND, new IntPtr(SC_KEYMENU), new IntPtr(115)); // 's' key and added a submenu option as &Search, but it doesn't make any difference

• jquery error() calls showing up in firebug profile

  - by Aros

  I am working on an ASP.NET application that make a lot of jquery and javascript calls and trying to optimize the client side code as much as possible. (This web application is only designed to run on special hardware that has very low memory and processing power.) The profiler in firebug is great for figuring out what calls are taking up the most time. I have already optimized a lot of my selectors and it is much faster. However the profile shows a lot of jquery error() calls. In the attached image of the firebug profile window you can see it was called 52 times, accounting for 15.4 of the processing time. Is that normal for jquery to call its error() like that? My code works flawlessy, and there are no error messages in the firefox error console. It seems like that is a significant performance hit. Is there anyway to get more info on what the errors are? Thanks.

• C# WMI, Performance Counters, & SNMP Oh My!

  - by Keith

  I have a C# windows service which listens to a MSMQ and sends each message out as an email. Since there's no UI, I'd like to offer an ability to monitor this service to see things such as # messages in queue, # emails sent (by message type perhaps), # of errors, etc. What is the best/recommended way to accomplish this? Is it WMI or performance counters? Is this data viewed using PerfMon or WMI CIM Studio? Does any approach allow one to monitor the service real-time as well as providing historical analysis? I can dig into the details myself but would appreciate some broad guidance to help demystify this subject.

• MySql order by problem

  - by Sergio

  Hello. I want to list messages that received specific user from other users group by ID's and ordered by last message received. If I use this query: SELECT MAX(id), fromid, toid, message FROM pro_messages WHERE toid=00003 GROUP BY fromid I do not get last message sent from user "fromid" to user "toid" but the first message sent. Can I do that in some other way or I need to do it with two queries or join tables? id - message id fromid - id of user who sent message toid - id of user who receive message (in this case user 00003)

• jQuery trigger uploadify click event not working in firefox FF

  - by drew

  I want to select an option on a drop down box and for this to trigger the uploadify available to jQuery which lets you upload a file. My solution works in IE7 but not FF. When you change the drop down it should show a window to browse for a file to upload. In FF nothing appears. In IE everything works. JS is enabled in FF, if I insert alert messages it gets to the point of triggering the click on the input button. 0 1 $(document).ready(function() { $('.fileupload1').uploadify({ 'uploader' : '../../../admin/uploadFileResources/uploadify.swf', 'script' : '../../../admin/uploadFileResources/upload.cfm', 'cancelImg' : '../../../admin/uploadFileResources/cancel.png', 'folder' : '../../../upload_BE/offers/htmlfiles/5953/images/', 'multi' : true }); $('.selectLogoTop').change(function(){ $('.fileupload1').trigger("click"); }); });

• Python (Twisted) - reading from fifo and sending read data to multiple protocols

  - by SpankMe

  Hi, Im trying to write some kind of multi protocol bot (jabber/irc) that would read messages from fifo file (one liners mostly) and then send them to irc channel and jabber contacts. So far, I managed to create two factories to connect to jabber and irc, and they seem to be working. However, I've problem with reading the fifo file - I have no idea how to read it in a loop (open file, read line, close file, jump to open file and so on) outside of reactor loop to get the data I need to send, and then get that data to reactor loop for sending in both protocols. I've been looking for information on how to do it in best way, but Im totally lost in the dark. Any suggestion/help would be highly appreciated. Thanks in advance!

• Why is -[UISwitch superlayer] being called?

  - by Jonathan Sterling

  I've got sort of a crazy thing going on where I have an NSProxy subclass standing in for a UISwitch. Messages sent to the proxy are forwarded to the switch. Please don't comment on whether or not this is a good design, because in context, it makes sense as an incredibly cool thing. The dealio is that when I try to add this object as an accessory view to a UITableViewCell, I get the following crash: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UISwitch superlayer]: unrecognized selector sent to instance 0x5889740' Yes, I could just set the proxy's target as the accessory view, but then I would have to keep track of the proxy so that I could release it at the right time. So, what I really want is to be able to have the proxy retained by the table cell, and released when it is removed from the view just like a normal accessory view. So, why is -[UISwitch superlayer] (a method which does not exist) being called, and how do I save the world?

• How to digitally sign a message with M2Crypto using the keys within a DER format certificate

  - by Pablo Santos

  Hi everyone. I am working on a project to implement digital signatures of outgoing messages and decided to use M2Crypto for that. I have a certificate (in DER format) from which I extract the keys to sign the message. For some reason I keep getting an ugly segmentation fault error when I call the "sign_update" method. Given the previous examples I have read here, I am clearly missing something. Here is the example I am working on: from M2Crypto.X509 import * cert = load_cert( 'certificate.cer', format=0 ) Pub_key = cert.get_pubkey() Pub_key.reset_context(md='sha1') Pub_key.sign_init() Pub_key.sign_update( "This should be good." ) print Pub_key.sign_final() Thanks in advance for the help, Pablo

• StringLengthValidator - localization not working

  - by danysdragons

  I am validating input to my ASP.NET application using StringLengthValidators, and using the ValidationSummary control to display the error messages. To localize the application, the StringLengthValidators have the MessageTemplateResourceName and MessageTemplateResourceType attributes set. The first time the validator runs, it picks up the correct error message based on the current culture setting. If I change the language setting while running the app, the next time the validator runs, the ValidationSummary it still displays the error message for the old culture. The text for all other controls is being updated correctly. Any ideas, folks?

• What is all this stuff in the CKEditor folder?

  - by Ashley Ward

  A while ago I downloaded the latest version (3.1) of the CKEditor text editor. The directory name was ckeditor and I deleted the ckeditor/_source and ckeditor/_samples sub-directories, then I referenced the ckeditor.js file in my html pages, like so : <script type="text/javascript" src="ckeditor/ckeditor.js"></script> this works well. To make config changes, I have been modifying the ckeditor/config.js file. However, as of late, I have been reading various web resources that say 'do not delete the _source' folder and other such ominous messages. What is this _source folder? What is all the stuff at the root of the ckeditor folder? and, What is safe to remove from the folder?

• Team Build MSBuild Task Does Not Update Main Build Log File

  - by NotMyself

  I have an after build event in my main TFSBuild.proj file that uses the MSBuild task to call a deployment task after a successful build. It looks like this: <ItemGroup> <DeploymentTargets Include="..\Sources\Build\SkunkWorks.Build.Deployment.targets"> <Properties></Properties> </DeploymentTargets> </ItemGroup> <Target Name="AfterBuild"> <Message Text="Executing Deployment"/> <MSBuild Projects="@(DeploymentTargets)" Properties="PickUpLocation='@(DropLocation)'" ContinueOnError="false"/> </Target> This works fine and the deployment script is called as you would expect. The problem is that any errors or messages produced by executing the MSBuild are not written to the BuildLog.txt or ErrorsAndWarnings.txt files that are placed in the drop location after a successful build. Is there an easy way to capture this information?

  At work, we have a client-server system where clients submit requests to a web server through HTTP. The server-side processing can sometimes take more than 60 seconds, which is the proxy timeout value set by our company's IT staff and cannot be changed. Is there a way to keep the HTTP connection alive for longer than 60 seconds (preferably for an arbitrarily long period of time), either by heartbeat messages from the server or the client? I know there are HTTP 1.1 persistent connections, but that is not what I want. Does HTTP have a keep-alive capability, or would this have to be done at the TCP level through some sort of socket option?

• What response Adobe Acrobat/Reader gets back after submitting form to a PHP script

  - by Laszlo

  Hi, PDF experts help needed, I am posting a form from PDF to a PHP script with Adobe Acrobat. I would like to set my PDF to display appropiate messages based upon some returned values. So I am looking for returned values... if there is any returned values after posting the form, how can I access them? Maybe, there is an option to set this in Adobe? Another thing: When the PDF form gets submitted and let's say I echo back a 'thank you' message from my form-handler PHP script, a new PDF gets created and opened displaying my message... is there a way to open that new message in the same window and close the form instead? Thanks, Laz

• Performing both client side and server side validation using jQuery and CodeIgniter

  - by Vasu

  What is the right way of doing both client side and server side validation using jQuery and CodeIgniter? I am using the jQuery form plugin for form submit. I would like to use jQuery validation plugin (http://docs.jquery.com/Plugins/Validation) for client side validation and CodeIgniter form validation on the server side. However the two don't seem to gel together (or I am unable to get my head around it). Can someone help please? Whether its a client side validation or server side validation, the user should see consistent UI displaying error messages next to the input fields.

• WebDAV auto-versioning in Git or Hg or any modern VCS

  - by Marcus P S

  I just recently learned of SVN's auto-versioning feature for WebDAV. Although I understand this is not replacement for proper versioning, with messages documenting change sets, it strikes me as a solid and safe replacement to Dropbox (minus nice GUIs and web pages). However, since commits in auto-versioning are frequent, I'd imagine that Git or Hg would be better suited for this, just because of their more compact databases (although I wonder if the distributed nature of things could make the automation ugly for resolving conflicts). Is this a feature that has been implemented using Git or Hg, as far as anyone knows?

• Java HTML parser/validator

  - by at

  We allow people to enter HTML code on our wiki-like site. But only a limited subset of HTML to not affect our styling and not allow malicious javascript code. Is there a good Java library on the server side to ensure that the code entered is valid? We tried creating an XML Schema document to validate against. The only issue there is the libraries we used to validate gave back cryptic error messages. What I want is for the validation library to actually fix the issue (if there was a style="" attribute added to an element, remove it). If fixing it is not easy, at least allow me to report a message to the user with the location of the error (an error code that I can present a nice message from is fine, probably even preferable).

• xCode "Property access results unused - getters should not be used for side effects"

  - by David DelMonte

  Hi all, I'm getting this warning when I'm calling a local routine. My code is this: -(void)nextLetter { // NSLog(@"%s", __FUNCTION__); currentLetter ++; if(currentLetter > (letters.count - 1)) { currentLetter = 0; } self.fetchLetter; } I'm getting the warning on the self.fetchLetter statement. That routine looks like this: - (void)fetchLetter { // NSLog(@"%s", __FUNCTION__); NSString *wantedLetter = [[letters objectAtIndex: currentLetter] objectForKey: @"langLetter"]; NSString *wantedUpperCase = [[letters objectAtIndex: currentLetter] objectForKey: @"upperCase"]; ..... } I prefer to fix warning messages, is there a better way to write this? Thanks!
