  • COM/DCOM problem when hosting executable is run as a service

    - by Mitch
    I am struggling for days now with the following problem: We have an executable that hosts a COM server, say x.exe. The COM object is instantiated as follows on the calling site: hRes = CoCreateInstance(CLSID_InterceptX, NULL, CLSCTX_SERVER, IID_IInterceptX, (void**)&pInterceptX); It all works fine when x runs as an regular application. We have a tool (I don't know how it works) that encapsulates x.exe so that it runs as a service under Windows (x.exe is a running process). In this case, we never receive a COM call in x.exe (validated by logging). Here is the weird part: From logging the calling site, I can tell that the COM object has been successfully instantiated and also the call to an interface function does not produce an error (SUCEEDED(hres) is true). Any ideas?

  • Python Mindstorms RCX

    - by Kyle Schmidt
    I've got 30 unopened Lego Mindstorms kits that I'd love to use in my intro programming class to do some simple robotics stuff at the end of the year. We're using Python in the class, so I'd prefer there to be a way for the kids to write the programs in Python. Unfortunately, these are old kits with RCX bricks - not the newer NXT ones, so most of the projects like NXT_Python can't help me. Is there any way to make that happen?

  • iPad popover - resignFirstResponder issue

    - by mosdev
    I have two text fields email and password. The following code works fine when the fields are presented on a regular view but when they are on a popover, the resignFirstResponder does not work (becomeFirstResponder works). textFieldsShouldReturn was called for both fields. Any idea if I am missing something? Thanks! - (BOOL)textFieldShouldReturn:(UITextField *)theTextField { if (theTextField == email) { [password becomeFirstResponder]; return NO; } [theTextField resignFirstResponder]; return NO; }

  • Regex Problem in PHP

    - by Chris
    I'm attempting to utilize the following Regex pattern: $regex = '/Name: [a-zA-Z ]*] [0-9]/'; When testing it in Rubular, it works fine, but when using PHP the expression never returns true, even when it should. Incidentally, if I remove the "[0-9]" part, it works fine. Is there some difference in PHP's regex syntax that I'm overlooking? Edit: I'm looking for the characters "Name:" then a name containing any number of letters or spaces, then a "]", then a space, then a single number. So "Name: Chris] 5" would return true and "Name: Chris] [lorem ipsum]" should return false. I also tried escaping the second bracket "\[" but this did not fix the problem.

  • Why is ContextConfiguration location different in idea and eclipse

    - by jakob
    Hello experts. In my team we work both in Eclipse and Idea. That works pretty good, except for one minor issue that I can't figure out how to solve. When setting the ContextConfiguration location in our tests and running them inside Eclipse everything works like a charm: @Test(groups = { "database" }) @ContextConfiguration(locations = {" file:src/main/webapp/WEB-INF/applicationContext.xml" }) But in my Idea env I get "could not find applicationContext" error. I need to set the location like this(project name is services): @Test(groups = { "database" }) @ContextConfiguration(locations = {" file:services/src/main/webapp/WEB-INF/applicationContext.xml" }) The project structure is like this: parent.pom with two child poms: services.pom and other.pom. When running the test in the terminal from the service project like this: mvn -Dtest=com.mytest.service.somepackage.TheTest test there are no issues. I guess that since my project structure is parent-with-two-children the need of /service is necessary(The project is created by pointing out the parent pom). Is there a way to fix this? Could you please help me with a solution. thx

  • Why does mysqldump need to be fully pathed when called from a controller or model?

    - by Kris
    When I call mysqldump from a controller or model I need to fully path the binary, when I call it from Rake I don't need to. If I do not fully path I get a zero byte file... I can confirm both processes are run using the same user. # Works in a controller, model and Rake task system "/usr/local/mysql/bin/mysqldump -u root #{w.database_name} > #{target_file}" # Only works in a Rake task system "mysqldump -u root #{w.database_name} > #{target_file}" If I call the Rake task from the action it also fails (zero byte file). OS: Mac Ruby 1.8.6 EDIT: I use Etc.getpwuid(Process.uid).name to get the User of the current process

  • Collection View Item binding issue

    - by Harry
    I have two entities in a Data Model, ENTITY_A, and ENTITY_B, that are related (ENTITY_A with a one-to-many relationship to ENTITY_B named DetailItems). I have set up a NSCollectionView with its appropriate bindings to ENTITY_A, and have placed on a Collection View Item a label. If I bind the label to [Collection View Item] and with a Model Key Path of [representedObject.FIELD_NAME], it works great. If I bind it to a Model Key Path [representedObject.DetailItems.@count], again it works great. If I bind it to a Model Key Path [[email protected]_NAME], I get the following error on the console: addObserver:forKeyPath:options:context:] is not supported. Key path: @sum.FIELD_NAME. Can anyone please help? Thank you, Harry

  • Python enumerate built-in error when using the start parameter

    - by TheJuice
    I'm modifying some code that calls enumerate on a list declared via a list comprehension e.g. self.groups = [Groups(self, idx) for idx in range(n_groups)] then later: for idx, group in enumerate(self.groups): # do some stuff but when I change the enumerate call to start at the 2nd list element via the start parameter e.g. for idx, group in enumerate(self.groups[1]): I get an exception: exceptions.TypeError: 'Group' object is not iterable Could someone explain why this is?

  • Why does Chrome ignore local jQuery cookies?

    - by Nathan Long
    I am using the jQuery Cookie plugin (download and demo and source code with comments) to set and read a cookie. I'm developing the page on my local machine. The following code will successfully set a cookie in FireFox 3, IE 7, and Safari (PC). But if the browser is Google Chrome AND the page is a local file, it does not work. $.cookie("nameofcookie", cookievalue, {path: "/", expires: 30}); What I know: The plugin's demo works with Chrome. If I put my code on a web server (address starting with http://), it works with Chrome. So the cookie fails only for Google Chrome on local files. Possible causes: Google Chrome doesn't accept cookies from web pages on the hard drive (paths like file:///C:/websites/foo.html) Something in the plugin implentation causes Chrome to reject such cookies Can anyone confirm this and identify the root cause?

  • How to insert JSP functionality in Servlets?

    - by chustar
    How can I use Servlets to access the HTML uses of having JSP without having to have all my client-facing pages called *.jsp? I would rather do this than using all the response.write() stuff because I think it is easier to read and maintain when it is all clean "HTML". Is this is fair assesment?

  • OAuth iPhone client, problems with HTTP_AUTHORIZATION

    - by Rich
    Hi, I've been trying to implement OAuth in my iPhone app. However I have hit a problem. I have two servers, a local web server which is on my machine at home, I use this for testing. The machine is IIS 7 running PHP 5.08. Everything works fine on this server. However my live (web server) is running Apache and PHP 5.12. The problem is when I try to request a RequestToken the HTTP_AUTHORIZATION variable isn't posted to the web server, so I get an error returned from the server saying 'Invaild Consumer Key'. There is clearly a problem with the way the server is setup (as the code works on my local server). The code I am using is from this walkthrough http://code.google.com/p/oauthconsumer/wiki/UsingOAuthConsumer I have tried dumping the PHP headers and indeed HTTP_AUTHORIZATION is missing. Can anyone tell me how to fix this? (as it's driving me mad :)) Thanks Rich

  • How can I learn a multitouch screen's communication protocol and write a C# application for it?

    - by puri
    I have got a monitor with multitouch overlay on top of it. It works fine with Windows 7 but I want to write a multitouch application in C# for Windows XP which doesn't support touch feature out of the box. There is no documentation whatsoever and I emailed the manufacturer but never got a reply. However the device works with Google Earth, which doesn't natively support multitouch, on Windows XP. So I think it generates many types of messages together i.e. WM_TOUCH for Windows 7, one for Google Earth COM API, and probably its own messages either in UDP or Windows message form. How can I trap all communications and learn the protocol?

  • php cURL POST how to follow location

    - by webfac
    Hi Guys, I am in a bit of a rut with a cURL issue. The post works greate, the data is POSTED just fine and received ok, but the url of the posted page never appears in the browser after the cURL session is executed, for example look at the following code: $ch = curl_init("http://localhost/eterniti/cart-step-1.php"); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, "error=1&em=$em&fname=$fname&lname=$lname&email1=$email1&email2=$email2&code=$code&area=$area&number=$num&mobile=$mobile&address1=$address1&address2=$address2&address3=$address3&suburb=$suburb&postcode=$postcode&country=$country"); curl_exec($ch); curl_close($ch); The post works fine and I am taken to the cart-step-1.php where I can process the posted data, HOWEVER the location in the URL address bar of the browser remains that of the script page, in this case proc_xxxxxx.php Any ideas how to get the URL address to reflect the page I am actually POSTED to? Thanks a mill

  • How to implement a left outer join in the Entity Framework.

    - by user206736
    I have the following SQL query:- select distinct * from dbo.Profiles profiles left join ProfileSettings pSet on pSet.ProfileKey = profiles.ProfileKey left join PlatformIdentities pId on pId.ProfileKey = profiles.Profilekey I need to convert it to a LinqToEntities expression. I have tried the following:- from profiles in _dbContext.ProfileSet let leftOuter = (from pSet in _dbContext.ProfileSettingSet select new { pSet.isInternal }).FirstOrDefault() select new { profiles.ProfileKey, Internal = leftOuter.isInternal, profiles.FirstName, profiles.LastName, profiles.EmailAddress, profiles.DateCreated, profiles.LastLoggedIn, }; The above query works fine because I haven't considered the third table "PlatformIdentities". Single left outer join works with what I have done above. How do I include PlatformIdentities (the 3rd table) ? I basically want to translate the SQL query I specified at the beginning of this post (which gives me exactly what I need) in to LinqToEntities. Thanks

  • How can I use Spring Security without sessions?

    - by Jarrod
    I am building a web application with Spring Security that will live on Amazon EC2 and use Amazon's Elastic Load Balancers. Unfortunately, ELB does not support sticky sessions, so I need to ensure my application works properly without sessions. So far, I have setup RememberMeServices to assign a token via a cookie, and this works fine, but I want the cookie to expire with the browser session (e.g. when the browser closes). I have to imagine I'm not the first one to want to use Spring Security without sessions... any suggestions?

    The title is pretty much the extent of my question. I am trying to insert a large table into a document using the xtabular environment. If I wrap the xtabular environment in a landscape environment, then the bottom of my table gets chopped off. Does anyone have any better suggestions? Thanks \begin{landscape} \singlespace \begin{xtabular}{|c|c|c|c|c|} \hline some & stuff & ... & \\ \end{xtabular} \end{landscape} Tim

  • Ruby Oauth File upload/Multipart POST request

    - by Jonas Söderström
    Hi I've been looking at this for a couple of hours now and haven't found a solution. Is there a way to upload a file using OAuth-Ruby? When I send a normal request, everything works but adding a file as a parameter makes the signature invalid. Example: @access_token.post("http://.../imageresource", {:name=>"awesome cat"}) works great but gives me: <error> <message>images/POST: Request has neither file data nor a fileUrl from which to download data</message> </error> Any thoughts on this? Thanks,

  • Why is Perl commonly used for writing CGI scripts?

    - by Michael Vasquez
    I plan to add a better search feature to my site, so I thought that I would write it in C and use the CGI as a means to access it. But it seems that Perl is the most popular language when it comes to CGI-based stuff. Why is that? Wouldn't it be faster programmed in C or machine code? What advantages, if any, are there to writing it in a scripting language? Thanks.
