  • Send SYN packet in C#?

    - by Petr
    Hi, I am wondering whether it is even possible or I cannot do such a raw socket manipulation? If so, how can I try it? I am not trying to do this old DoS attack, just curious how to send it thru C#. Thanks

  • Using QTDesigner with PyQT and Python 2.6

    - by PyNewbie27
    Hi. I'm fairly new to Python and trying to work with the latest versions of QTDesigner, PyQT 4.7 and QT4.7 (I downloaded the whole package from PyQT4.7 website). I can't figure out how to make QTDesigner integrate closely with Python: ie. If I select "Form" View Code in QTDesigners menu, it errors saying "Unable to launch C:/Python26/Lib/site-packages/PyQT4/bin\uic." If I look in that directory there is a pyuic.py but not "uic". From searching online it seems this doesn't exist because it's expecting a C++ install instead of the python version. Is there anyway to make QTDesigner use/call pyuic.py to generate the code, then open an IDE or text editor of my choice to show me the PYTHON code generated by the QTDesigner-PyUIC chain? I'd like Designer to integrate closely with python, so I can make custom slots/signals in Designer while designing, then tweak the python code directly in my IDE later. If it is not possible to code directly inside QTDesigner using python, does that mean I have to hand code my programs entire UI directly in my PythonIDE? Using Designer directly would seemingly be nearly very very nice for a newbie such as myself, since I can see what properties each widget has and visually edit them while still learning the QT syntax without constantly having to use web resources to see what properties each widget should have and helps with boilerplate code generation, and what their defaults are, etc. I've googled and nobody seems to be using QTDesigner and Python in this manner together. It seems most are either handcoding all the QT code in their Python IDE of choice, or have found an obvious/easy method of doing what I want, therefore not really producing up to date tutorials on making this work together. Please enlighten me if you can. Thanks in advance for your time. Please include any suggestions you might have to a newbie trying to use Python with QT and QTDesigner. Thank you.

  • Getting started with Exchange Web Services 2010

    - by Adam Tuttle
    I've been tasked with writing a SOAP web-service in .Net to be middleware between EWS2010 and an application server that previously used WebDAV to connect to Exchange. (As I understand it, WebDAV is going away with EWS2010, so the application server will no longer be able to connect as it previously did, and it is exponentially harder to connect to EWS without WebDAV. The theory is that doing it in .Net should be easier than anything else... Right?!) My end goal is to be able to get and create/update email, calendar items, contacts, and to-do list items for a specified Exchange account. (Deleting is not currently necessary, but I may build it in for future consideration, if it's easy enough). I was originally given some sample code, which did in fact work, but I quickly realized that it was outdated. The types and classes used appear nowhere in the current documentation. For example, the method used to create a connection to the Exchange server was: ExchangeService svc = new ExchangeService(); svc.Credentials = new WebCredentials(AuthEmailAddress, AuthEmailPassword); svc.AutodiscoverUrl(AutoDiscoverEmailAddress); For what it's worth, this was using an assembly that came with the sample code: Microsoft.Exchange.WebServices.dll ("MEWS"). Before I realized that this wasn't the current standard way to accomplish the connection, and it worked, I tried to build on it and add a method to create calendar items, which I copied from here: static void CreateAppointment(ExchangeServiceBinding esb) { // Create the appointment. CalendarItemType appointment = new CalendarItemType(); ... } Right away, I'm confronted with the difference between ExchangeService and ExchangeServiceBinding ("ESB"); so I started Googling to try and figure out how to get an ESB definition so that the CreateAppointment method will compile. I found this blog post that explains how to generate a proxy class from a WSDL, which I did. Unfortunately, this caused some conflicts where types that were defined in the original Assembly, Microsoft.Exchange.WebServices.dll (that came with the sample code) overlapped with Types in my new EWS.dll assembly (which I compiled from the code generated from the services.wsdl provided by the Exchange server). I excluded the MEWS assembly, which only made things worse. I went from a handful of errors and warnings to 25 errors and 2,510 warnings. All kinds of types and methods were not found. Something is clearly wrong, here. So I went back on the hunt. I found instructions on adding service references and web references (i.e. the extra steps it takes in VS2008), and I think I'm back on the right track. I removed (actually, for now, just excluded) all previous assemblies I had been trying; and I added a service reference for https://my.exchange-server.com/ews/services.wsdl Now I'm down to just 1 error and 1 warning. Warning: The element 'transport' cannot contain child element 'extendedProtectionPolicy' because the parent element's content model is empty. This is in reference to a change that was made to web.config when I added the service reference; and I just found a fix for that here on SO. I've commented that section out as indicated, and it did make the warning go away, so woot for that. The error hasn't been so easy to get around, though: Error: The type or namespace name 'ExchangeService' could not be found (are you missing a using directive or an assembly reference?) This is in reference to the function I was using to create the EWS connection, called by each of the web methods: private ExchangeService getService(String AutoDiscoverEmailAddress, String AuthEmailAddress, String AuthEmailPassword) { ExchangeService svc = new ExchangeService(); svc.Credentials = new WebCredentials(AuthEmailAddress, AuthEmailPassword); svc.AutodiscoverUrl(AutoDiscoverEmailAddress); return svc; } This function worked perfectly with the MEWS assembly from the sample code, but the ExchangeService type is no longer available. (Nor is ExchangeServiceBinding, that was the first thing I checked.) At this point, since I'm not following any directions from the documentation (I couldn't find anywhere in the documentation that said to add a service reference to your Exchange server's services.wsdl -- but that does seem to be the best/farthest I've gotten so far), I feel like I'm flying blind. I know I need to figure out whatever it is that should replace ExchangeService / ExchangeServiceBinding, implement that, and then work through whatever errors crop up as a result of that switch... But I have no idea how to do that, or where to look for how to do it. Googling "ExchangeService" and "ExchangeServiceBinding" only seem to lead back to outdated blog posts and MSDN, neither of which has proven terribly helpful thus far. Help me, Obi-Wan, you're my only hope!

  • Advice on database design / SQL for retrieving data with chronological order

    - by Remnant
    I am creating a database that will help keep track of which employees have been on a certain training course. I would like to get some guidance on the best way to design the database. Specifically, each employee must attend the training course each year and my database needs to keep a history of all the dates on which they have attend the course in the past. The end user will use the software as a planning tool to help them book future course dates for employees. When they select a given employee they will see: (a) Last attendance date (b) Projected future attendance date(i.e. last attendance date + 1 calendar year) In terms of my database, any given employee may have multiple past course attendance dates: EmpName AttandanceDate Joe Bloggs 1st Jan 2007 Joe Bloggs 4th Jan 2008 Joe Bloggs 3rd Jan 2009 Joe Bloggs 8th Jan 2010 My question is what is the best way to set up the database to make it easy to retrieve the most recent course attendance date? In the example above, the most recent would be 8th Jan 2010. Is there a good way to use SQL to sort by date and pick the MAX date? My other idea was to add a column called ‘MostRecent’ and just set this to TRUE. EmpName AttandanceDate MostRecent Joe Bloggs 1st Jan 2007 False Joe Bloggs 4th Jan 2008 False Joe Bloggs 3rd Jan 2009 False Joe Bloggs 8th Jan 2010 True I wondered if this would simplify the SQL i.e. SELECT Joe Bloggs WHERE MostRecent = ‘TRUE’ Also, when the user updates a given employee’s attendance record (i.e. with latest attendance date) I could use SQL to: Search for the employee and set the MostRecent value to FALSE Add a new record with MostRecent set to TRUE? Would anybody recommended either method over the other? Or do you have a completely different way of solving this problem?

  • AutoCompleteExtender - authentication failure (forms authentication)

    - by Paddy
    I'm using the AutoCompleteExtender from the AJAX control toolkit on my aspx page - I have it wired up to a WCF service that is returning a string array and everything works happily. If I change my service definition to include a demand for the caller to be authenticated, like so: <OperationContract(), PrincipalPermission(SecurityAction.Demand, Authenticated:=True)> _ Public Function GetLookupValues(ByVal prefixText As String, ByVal count As Integer, ByVal contextKey As String) As String() Then the autocomplete extender stops working, and I get an authentication error in the service. The service is set up to use ASPNetCompatibility mode, and I was hoping that the extender would pass the authentication credentials for my logged in user - does anyone know how to make this work?

  • Spring rejecting bean name, no URL paths specified

    - by richever
    I am trying to register an interceptor using a annotation-driven controller configuration. As far as I can tell, I've done everything correctly but when I try testing the interceptor nothing happens. After looking in the logs I found the following: 2010-04-04 20:06:18,231 DEBUG [main] support.AbstractAutowireCapableBeanFactory (AbstractAutowireCapableBeanFactory.java:452) - Finished creating instance of bean 'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping#0' 2010-04-04 20:06:18,515 DEBUG [main] handler.AbstractDetectingUrlHandlerMapping (AbstractDetectingUrlHandlerMapping.java:86) - Rejected bean name 'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping#0': no URL paths identified 2010-04-04 20:06:19,109 DEBUG [main] support.AbstractBeanFactory (AbstractBeanFactory.java:241) - Returning cached instance of singleton bean 'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping#0' Look at the second line of this log snippet.

  • JPQL IN clause: Java-Arrays (or Lists, Sets...)?

    - by Bernd Haug
    I would like to load all objects that have a textual tag set to any of a small but arbitrary number of values from our database. The logical way to go about this in SQL would be to build an "IN" clause. JPQL allows for IN, but it seems to require me to specify every single parameter to IN directly (as in, "in (:in1, :in2, :in3)"). Is there some way to specify an array, or a list (or some other container) that should be unrolled to the values of an IN clause?

  • About unit testing a function in the zend framework and unit testing in general

    - by sanders
    Hello people, I am diving into the world of unit testing. And i am sort of lost. I learned today that unit testing is testing if a function works. I wanted to test the following function: public function getEventById($id) { return $this->getResource('Event')->getEventById($id); } So i wanted to test this function as follows: public function test_Event_Get_Event_By_Id_Returns_Event_Item() { $p = $this->_model->getEventById(42); $this->assertEquals(42, EventManager_Resource_Event_Item_Interface); $this->assertType('EventManager_Resource_Event_Item_Interface', $p); } But then I got the error: 1) EventTest::test_Event_Get_Event_By_Id_Returns_Event_Item Zend_Db_Table_Exception: No adapter found for EventManager_Resource_Event /home/user/Public/ZendFramework-1.10.1/library/SF/Model/Abstract.php:101 /var/www/nrka2/application/modules/eventManager/models/Event.php:25 But then someone told me that i am currently unit testing and not doing an integration test. So i figured that i have to test the function getEventById on a different way. But I don't understand how. What this function does it just cals a resource and returns the event by id.

  • OpenCV Video capture and fps problem

    - by Andrea Girardi
    Hi to all, I'm capturing video from my webcam using OpenCV on MacOSX. It works fine but when I try to play on QuickTime my captured video it plays too fast. i.e. I capture from camera for 10 seconds but when I play on QuickTime the video is 2 seconds. I've tried to change fps from 25 to 10 and It's works quite fine, but I'm sure it's not the correct process: CvVideoWriter *writer = 0; int isColor = 1; int fps = 25; int frameW = 640; // 744 for firewire cameras int frameH = 480; // 480 for firewire cameras The problem is that for now I've to capture with WebCam but the real pourpose of program is to capture image from any external source connected to my Mac. I'm using this code to capture: for (;;) { cvGrabFrame(capture) image = cvRetrieveFrame(capture); cvWriteFrame( writer, image ); } Any hint? I'm also showing webcam output on cvNamedWindow, how can I improve quality in this windows? thanks a lot to all! Andrea!

    I converted a Winforms project by hand-editing the proj file. Changed project type guids and added an application definition section, and now I can add WPF Windows, Pages, etc. to the project. One thing that doesn't work is, the files I added do not have autogenerated cs files, and every new window component are missing their InitializeComponent method. Any ideas?

  • XP Deploying issues due to msvcr90.dll trying to load FlsAlloc

    - by Sorin Sbarnea
    I have an application build with VS2008 SP1a (9.0.30729.4148) on Windows 7 x64 that does not want to start under XP. The message is The application failed to initialize properly (0x80000003). Click on OK to terminate the application.. I checked with depends.exe and found that msvcr90.dll does try to load FlsAlloc from KERNEL32.dll - and FlsAlloc is available only starting with Vista.

  • WiX/Windows Installer: Re-install to a new folder

    - by vitalyval
    1. I am using WiX for creating installer and would like to implement the following behaviour: If a user launches msi installer for the product and the product already installed, then wizard works similar to pure (first time) installation with exception of some things (e.g. license aggrement screen is omitted). The wizard should allow for example to change installation folder, select whether to place desktop shortcut,... I tried to do: <Publish Event="ReinstallMode" Value="amus"><![CDATA[INSTALL_MODE = "Change"]]></Publish> <Publish Event="Reinstall" Value="ALL"><![CDATA[INSTALL_MODE = "Change"]]></Publish> But after installation completes: the product is in the same folder, where it was installed first time; desktop icon in the same state as it was after first time install. MSDN says: "Do not attempt to change the target directory path if some components that use the path are already installed for the current user or for a different user". Is there a way to re-install in another forlder and add/remove desktop icon in re-install? 2. Is this normal to use the same KeyPath for some components? For example the same registry values for DeskTop and Programs menu shortcuts? MSDN says: "Two components cannot share the same key path value". But compiling and verifying goes OK. And I did not discover problems using the same keypaths.

  • Extjs combobox - doQuery callback?

    - by Ben
    Hi there, I'm using the following combobox: var cb = new Ext.form.ComboBox({ store: someDs, fieldLabel: 'test', valueField:'name', displayField:'name_id', typeAhead: true, minChars: 3, triggerAction: 'query' }); So when the user typed in 3 chars, a query to the server is made showing the proper results. Now I try to make the user input programmatically usint the doQuery() function of the combobox. After calling the doQuery() method, I want to seledct an Item via setValue(). cb.doQuery('myval'); cb.setValue('myval'); The problem is that setValue() can't select the propper value, because at the time it is called, the request started through doQuery() hasn't finished. So I need something like a callback in which I could use setValue() - but doQuery() doesn't seem to have a callback function. any ideas? thanks!

  • Building Dynamic Classes in Objective C

    - by kjell_
    I'm a somewhat competent ruby programmer. Yesterday I decided to finally try my hand with Apple's Cocoa frameworks. Help me see things the ObjC way? I'm trying to get my head around objc_allocateClassPair and objc_registerClassPair. My goal is to dynamically generate a few classes and then be able to use them as I would any other class. Does this work in Obj C? Having allocated and registered class A, I get a compile error when calling [[A alloc] init]; (it says 'A' Undeclared). I can only instantiate A using runtime's objc_getClass method. Is there any way to tell the compiler about A and pass it messages like I would NSString? A compiler flag or something? I have 10 or so other classes (B, C, …), all with the same superclass. I want to message them directly in code ([A classMethod], [B classMethod], …) without needing objc_getClass. Am I trying to be too dynamic here or just botching my implementation? It looks something like this… NSString *name = @"test"; Class newClass = objc_allocateClassPair([NSString class], [name UTF8String], 0); objc_registerClassPair(newClass); id a = [[objc_getClass("A") alloc] init]; NSLog(@"new class: %@ superclass: %@", a, [a superclass]); //[[A alloc] init]; blows up.

  • SetWindowLong in CustomDraw causes unhandled exception

    - by neeul
    Hello, I am making some changes to a CSliderCtrl using the Custom Draw, the control is to be used in a dialog. Here is the structure: In my MessageMap I have : ON_NOTIFY_REFLECT_EX(NM_CUSTOMDRAW, OnNMCustomdraw) The OnNMCustomdraw method looks like the following: BOOL CCustomSliderCtrl::OnNMCustomdraw(NMHDR *pNMHDR, LRESULT *pResult) { *pResult = CDRF_DODEFAULT; LPNMCUSTOMDRAW pNMCD = reinterpret_cast<LPNMCUSTOMDRAW>(pNMHDR); switch(pNMCD->dwDrawStage) { case CDDS_PREPAINT: { //Dialogs don't receive CDRF_NOTIFYITEMDRAW notifcations by returning it as part of pResult, we must //use the following so we ensure we receive the msg SetWindowLong(pNMHDR->hwndFrom, DWL_MSGRESULT, CDRF_NOTIFYITEMDRAW); return TRUE; } case CDDS_ITEMPREPAINT: if(pNMCD->dwItemSpec == TBCD_CHANNEL) { ...SNIP... SetWindowLong(pNMHDR->hwndFrom, DWL_MSGRESULT, CDRF_SKIPDEFAULT); return TRUE; } } return FALSE; } Reading around I learnt that you had to use SetWindowLong to set the return value for the custom draw, otherwise your method will not always receive the CDDS_ITEMPREPAINT message. However, when using SetWindowLong my application will never receive the CDDS_ITEMPREPAINT and so my slider just looks like a standard slider. The application crashes when any sort of interaction takes place upon the slider, such as hovering over it or minimizing and maximizing the dialog. I snipped the TBCD_CHANNEL code as it is never reached. When running in debug mode, it crashes at the end of the AfxUnlockGlobals method, in afxcrit.cpp. Here is a stack trace: Update: Since adding debug symbols, the crash seems to be picked up at CWnd::DefWindowProc mwthod. comctl32.dll!_TrackBarWndProc@16() + 0x551 bytes user32.dll!_InternalCallWinProc@20() + 0x28 bytes user32.dll!_UserCallWinProcCheckWow@32() + 0xb7 bytes user32.dll!_CallWindowProcAorW@24() + 0x51 bytes user32.dll!_CallWindowProcW@20() + 0x1b bytes mfc90ud.dll!CWnd::DefWindowProcW(unsigned int nMsg=15, unsigned int wParam=0, long lParam=0) Line 1043 + 0x20 bytes C++ mfc90ud.dll!CWnd::WindowProc(unsigned int message=15, unsigned int wParam=0, long lParam=0) Line 1756 + 0x1c bytes C++ mfc90ud.dll!AfxCallWndProc(CWnd * pWnd=0x0012fdbc, HWND__ * hWnd=0x000308fe, unsigned int nMsg=15, unsigned int wParam=0, long lParam=0) Line 240 + 0x1c bytes C++ mfc90ud.dll!AfxWndProc(HWND__ * hWnd=0x000308fe, unsigned int nMsg=15, unsigned int wParam=0, long lParam=0) Line 403 C++ mfc90ud.dll!AfxWndProcBase(HWND__ * hWnd=0x000308fe, unsigned int nMsg=15, unsigned int wParam=0, long lParam=0) Line 441 + 0x15 bytes C++ user32.dll!_InternalCallWinProc@20() + 0x28 bytes user32.dll!_UserCallWinProcCheckWow@32() + 0xb7 bytes user32.dll!_DispatchClientMessage@20() + 0x4d bytes user32.dll!___fnDWORD@4() + 0x24 bytes ntdll.dll!_KiUserCallbackDispatcher@12() + 0x13 bytes user32.dll!_NtUserDispatchMessage@4() + 0xc bytes user32.dll!_DispatchMessageW@4() + 0xf bytes mfc90ud.dll!AfxInternalPumpMessage() Line 183 C++ mfc90ud.dll!CWinThread::PumpMessage() Line 900 C++ mfc90ud.dll!AfxPumpMessage() Line 190 + 0xd bytes C++ mfc90ud.dll!CWnd::RunModalLoop(unsigned long dwFlags=4) Line 4386 + 0x5 bytes C++ mfc90ud.dll!CDialog::DoModal() Line 584 + 0xc bytes C++ SetSelection.exe!CSetSelectionApp::InitInstance() Line 64 + 0xb bytes C++ mfc90ud.dll!AfxWinMain(HINSTANCE__ * hInstance=0x00400000, HINSTANCE__ * hPrevInstance=0x00000000, wchar_t * lpCmdLine=0x00020a84, int nCmdShow=1) Line 37 + 0xd bytes C++ SetSelection.exe!wWinMain(HINSTANCE__ * hInstance=0x00400000, HINSTANCE__ * hPrevInstance=0x00000000, wchar_t * lpCmdLine=0x00020a84, int nCmdShow=1) Line 34 C++ SetSelection.exe!__tmainCRTStartup() Line 578 + 0x35 bytes C SetSelection.exe!wWinMainCRTStartup() Line 403 C kernel32.dll!_BaseProcessStart@4() + 0x23 bytes So, does anyone have any insight into this matter?

  • Change/check minimum iPhone OS for Universal apps?

    - by Moshe
    The dropdown in XCode shows a base SDK of 3.2, but my iPod Touch (2nd generation), running OS 3.1.3, will run the app just fine in debug mode. (Command + Return/Enter) What is the actual base SDK of my iPhone/iPod touch version of the app and how can I change this? Changing it by right clicking on the project name in the "Groups and Files" pane and changing "Base SDK" under the "Build", doesn't do much. Edit: While writing this question, I found that scrolling down in "Build" and changing "iPhone OS Deployment Target" seems to be what I'm looking for, I'm posting this anyway. Perhaps someone has more insight into this...

  • ASP.NET MVC - ValidationMessageFor

    - by Murat
    Hi, I have asked this question on asp.net forums (http://forums.asp.net/t/1545006.aspx) but i had no valid answer therefore i'll try this here as well. I was working on migrating MVC1 app to MVC2 today and i have come across a problem while changing the ValidationMessage to ValidationMessageFor implementation. The below is the selectlist in my View <%=Html.DropDownListFor(model => model.SecurityQuestions[0].Question, "Some Security question", new { @class = "form_element_select" })%> The below code works fine and i can see the validation message came from modelstate. <%= Html.ValidationMessage("SecurityQuestions_0__Question")%> but this one does not work: <%= Html.ValidationMessageFor(model => model.SecurityQuestions[0].Question)%> SecurityQuestions is a generic list in my model public List<SecurityQuestion> SecurityQuestions { get; set; } Is this somewhat a bug in "ValidationMessageFor" or am i missing something here?
