  • virtual function call from base of base

    - by th3g0dr3d
    hi, let's say i have something like this (very simplified): <pre><code> class base { void invoke() { this-foo(); } virtual void foo() = 0; }; class FirstDerived : public base { void foo() { // do stuff } }; class SecondDerived : public FirstDerived { // other not related stuff } int main() { SecondDerived *a = new SecondDerived(); a-invoke(); } What i see in the debugger is that base::invoke() is called and tries to call this-foo(); (i expect FirstDerived::foo() to be called), the debugger takes me to some unfamiliar assembly code (probably because it jumped to unrelated areas) and after few lines i get segmentation fault. am i doing something wrong here? :/ thanks in advance

  • How to call windows authentication programmatically in sharepoint?

    - by HamdiKavak
    Hi guys, Here is my scenario. When anonymous user visits site collection's default site, custom login form panel is shown. This form is a webUserControl(.ascx file) that is embeded into page as webpart. Then user enters username and password. When submit button has been clicked, authentication will be handled by code behind of custom login form panel. Here is my question. How can I call SharePoint's authentication method with the username and password that is entered by user. Simply, I want users to login through my custom login form panel because default windows authentication window is looking really bad.

  • How to call web service with Android

    - by BobbyShaftoe
    I am having a lot of trouble finding good information on how to call a standard SOAP/WSDL web service with Android. All I've been able to find are either very convoluted documents and references to "kSoap2" and then some bit about parsing it all manually with SAX. ... Ok, that's fine but it's 2008 so I figured there should be some good library for calling standard web services. The Web Service is just basically one created in NetBeans. I would like to have IDE support for generating the plumbing classes. I just need the easiest/most-elegant way to contact a WSDL based web service from an Android based phone. Thanks.

  • Call named routes in CakePHP as the same way in Ruby on Rails

    - by Lucas Renan
    How can I call a route (in the view) in CakePHP as the same way in Rails? Ruby on Rails routes.rb map.my_route '/my-route', :controller => 'my_controller', :action => 'index' view link_to 'My Route Name', my_route_path CakePHP routes.php Router::connect('/my-route', array('controller' => 'my_controller', 'action' => 'index')); view $html->link('My Route Name', '/my-route'); But I think the Rails way is better, because I can make changes in the "url" and I don't need changes the code of the views.

  • Android: How to call call ndk function from AsyncTask?

    - by user1628803
    I have a lot of jni calls in my Android projects which work like a charm but this one I just can't get right: When trying to call a jni function from an AsyncTask in Android I get this error message: 11-30 10:07:20.130: W/dalvikvm(16555): No implementation found for native Lcom/company/MainView$MyAsyncTask;.MyFunction (Ljava/lang/String;)Z When usually the jni function declaration works like this: JNIEXPORT jboolean JNICALL Java_com_company_MainView_myFunction()... how would i declare it when calling from an AscnyTask? I didn't find the answer on Google and I have unsuccessfully tried: JNIEXPORT jboolean JNICALL Java_com_company_MainView$MyAsyncTask_myFunction() and JNIEXPORT jboolean JNICALL Java_com_company_MainView_MyAsyncTask_myFunction() Or is this not possible at all?

  • Need to call COM component using reflections in C#.NET

    - by Usman
    Hello, I need to determin the COM component(unmanaged code) type and invoke the exposed interface's methods using reflection in C#.NET at runtime. 1 -- First What member of "Type" tells that type is COM component and we can take CLSID at runtime? Is Type.COMObject? 2 -- I need to call methods of exposed interfaces as they called in unmanaged code using CoCreateInstance by passing CLSID and REFID ... I am using InvokeMember but it returns null or 0 as out parameter. How to pass out parameter in this case.? Is there any need to pass out parameter? As all my COM unamanged code suppose to take las parameter as an OUT parameter and after executing it puts the result into that out param. But I've converted all my unmanged COM code to .NET managed assemblies using tlbimp.exe. Regards Usman

  • Issue with CGEventTapCreate() call.

    - by Dheeraj
    Hi All, I'm trying to register for global key events using this code : void function() { CFMachPortRef keyUpEventTap = CGEventTapCreate(kCGHIDEventTap,kCGHeadInsertEventTap,kCGEventTapOptionListenOnly,CGEventMaskBit(kCGEventKeyUp),&keyUpCallback,NULL); CFRunLoopSourceRef keyUpRunLoopSourceRef = CFMachPortCreateRunLoopSource(NULL, keyUpEventTap, 0); CFRelease(keyUpEventTap); CFRunLoopAddSource(CFRunLoopGetCurrent(), keyUpRunLoopSourceRef, kCFRunLoopDefaultMode); CFRelease(keyUpRunLoopSourceRef); } The application crashes while executing CFMachPortCreateRunLoopSource() call. I think the crash is because of CGEventMaskBit(kCGEventKeyUp) when I create an event tap. But if I create event tap using CGEventTapCreate(kCGHIDEventTap,kCGHeadInsertEventTap,kCGEventTapOptionListenOnly,CGEventMaskBit(kCGEventFlagsChanged),&keyUpCallback,NULL), the application works fine. It does not crash. I'm getting callbacks when any modifier key is pressed. But I need to get callbacks for delete key pressed. Any ideas? Thanks, Dheeraj.

  • Call stored procedure using Spring SimpleJdbcCall with callback

    - by MFIhsan
    I have an Oracle Stored procedure that takes CLOB input and REFCURSOR output. I invoke the SP via Spring SimpleJdbcCall passing in a RowMapper to map the results. However, since the result set is large, I need to provide callback feature to the client. I can't quite figure out how to add callback for an SP call using Spring - both with and without SimpleJdbcCall. One thought I have is to pass-in a RowCallbackHandler. Will this work or is there a better way to solve this problem? Any help here is appreciated. private Map<String, Object> arguments = ...; SimpleJdbcCall jdbcCall = new SimpleJdbcCall(this.jdbcTemplate) .withCatalogName(this.packageName) .withProcedureName(this.storedProcName) .withoutProcedureColumnMetaDataAccess() .declareParameters(this.outputParameters.toArray(new SqlOutParameter[]{})); if(!isEmpty(inputParameters)) { jdbcCall.declareParameters(inputParameters.toArray(new SqlParameter[]{})); } this.outputParameters.add(new SqlOutParameter(outputParamName, VARCHAR, rowMapper)); jdbcCall.execute(arguments);

  • windows batch file to call remote executable with username and password

    - by Jake rue
    Hi I am trying to get a batch file to call an executable from the server and login. I have a monitoring program that allows me send and execute the script. OK here goes.... //x3400/NTE_test/test.exe /USER:student password Now this doesn't work. The path is right because when I type it in at the run menu in xp it works. Then I manually login and the script runs. How can I get this to login and run that exe I need it to? Part 2: Some of the machines have already logged in with the password saved (done manually). Should I have a command to first clear that password then login? Thanks for any replies, I appreciate the help Jake

  • UDF call in entity framework is cached

    - by Fred Yang
    I am doing a test after reading an article http://blogs.msdn.com/alexj/archive/2009/08/07/tip-30-how-to-use-a-custom-store-function.aspx about udf function called. When I use a function with objectContext.Entities.Where( t= udf(para1, para2) == 1), here the Entities is not ObjectQuery, but an ObjectSet, the first time I call the method, it runs correctly, if I reuse the objectContext,and run it again but with different para1, para2, then the previous parameter values still cached, and the result is same as previous one, which is wrong. The sql profiler shows that both query hit the database, but the t-sql is the same. Am I missing something? And the ObjectSet does not support .where(esql_string). How to get udf working with ObjectSet? Thanks Fred

  • Call a protected method from outside a class in PHP

    - by Chad Johnson
    I have a very special case in which I need to call a protected method from outside a class. I am very conscious about what I do programmingwise, but I would not be entirely opposed to doing so in this one special case I have. In all other cases, I need to continue disallowing access to the internal method, and so I would like to keep the method protected. What are some elegant ways to access a protected method outside of a class? So far, I've found this. I suppose it may be possible create some kind of double-agent instance of the target class that would sneakily provide access to the internals...

  • Got a minus one from a read call.

    - by sunyata
    I connect to a database with read only access using SQL developer. It's a TNS connection. I use a tnsnames.ora, forwarding port script and SQL Developer. In the past, occasionally, when connecting, I get a error message Got a minus one from a read call. Vendor Code 0 If I do a reboot, it goes away. Another friend suggested changed the forwarding port which worked for him. I recently upgraded to a new computer and now it seems that I am getting the error message consistently. Reboot or changing forwarding port does not help at all. The port forwarding script contains something like this putty -L ::1521 Does anybody have any idea? Thanks.

  • Modifying an old Windows program not to call exit after a keypress without source access

    - by rustyn2
    I have an older C++ Windows program that I've been asked to get run in a kiosk style environment for a student project. From the main menu, hitting ESC will exit the program, which is undesirable. In ye olden days I would have trapped the keyboard interrupt or whatever and dug around to NOOP whatever JMP or CALL was getting referenced in the case statement that likely decides all that, but on Windows everything goes through various registered event handlers, and I haven't done any windows internals work in about 10 years. Is there a good tool to breakpoint a program on certain WM_EVENT (WM_KEYDOWN being a prime target) messages or similar, so that I can narrow down where in the executable the check is made? I'm currently stepping back from various potential system calls made before the various thread cleanups and final exit calls but it seems like there has to be a better way to do this that I'm forgetting.
