  • Is there a way to add extra fields to an association in the ADO.NET Entity Framework?

    - by bigbird1040
    I would like to be able to model a many-to-many relationship that has extra details about the relationship. For example: Person: int id, String name Project: int id, String name ProjectPerson: Person.id, Project.id, String role Whenever I create the ProjectPerson association in the EF, I am unable to add the role attribute to the association. If I create the tables in my DB and then import it into the model, I lose the extra properties.

  • CInternetSession::OpenURL exception if headers are defined. Works fine if not. Why?

    - by Jesse
    Trying to log the application version details in our weblogs using the headers: Should be a one liner..but for some reason whenever I specify anything but NULL for the headers it causes an exception (InternetOpenUrl() call returns NULL) - anyone able to explain why? CInternetSession internet; CHttpFile * pHttpFile; CString headers;// = APPLICATION_SUITE_NAME; DWORD dwHeadersLength = -1; headers.Format("%s %s %s\n",APPLICATION_SUITE_NAME,SHORT_APPLICATION_VERSION,BUILDNO_STR); pHttpFile =(CHttpFile *) internet.OpenURL(lpszURL, 1, INTERNET_FLAG_TRANSFER_ASCII|INTERNET_FLAG_DONT_CACHE, headers, dwHeadersLength); Without the headers, dwHeadersLength parameter (eg. pass in NULL,-1) then it goes through fine and I see the request come through to our website. But why does it fail if I pass in custom headers?

  • How to dispose off custom object from within custom membership provider

    - by IrfanRaza
    I have created my custom MembershipProvider. I have used an instance of the class DBConnect within this provider to handle database functions. Please look at the code below: public class SGIMembershipProvider : MembershipProvider { #region "[ Property Variables ]" private int newPasswordLength = 8; private string connectionString; private string applicationName; private bool enablePasswordReset; private bool enablePasswordRetrieval; private bool requiresQuestionAndAnswer; private bool requiresUniqueEmail; private int maxInvalidPasswordAttempts; private int passwordAttemptWindow; private MembershipPasswordFormat passwordFormat; private int minRequiredNonAlphanumericCharacters; private int minRequiredPasswordLength; private string passwordStrengthRegularExpression; private MachineKeySection machineKey; **private DBConnect dbConn;** #endregion ....... public override bool ChangePassword(string username, string oldPassword, string newPassword) { if (!ValidateUser(username, oldPassword)) return false; ValidatePasswordEventArgs args = new ValidatePasswordEventArgs(username, newPassword, true); OnValidatingPassword(args); if (args.Cancel) { if (args.FailureInformation != null) { throw args.FailureInformation; } else { throw new Exception("Change password canceled due to new password validation failure."); } } SqlParameter[] p = new SqlParameter[3]; p[0] = new SqlParameter("@applicationName", applicationName); p[1] = new SqlParameter("@username", username); p[2] = new SqlParameter("@password", EncodePassword(newPassword)); bool retval = **dbConn.ExecuteSP("User_ChangePassword", p);** return retval; } //ChangePassword public override void Initialize(string name, NameValueCollection config) { if (config == null) { throw new ArgumentNullException("config"); } ...... ConnectionStringSettings ConnectionStringSettings = ConfigurationManager.ConnectionStrings[config["connectionStringName"]]; if ((ConnectionStringSettings == null) || (ConnectionStringSettings.ConnectionString.Trim() == String.Empty)) { throw new ProviderException("Connection string cannot be blank."); } connectionString = ConnectionStringSettings.ConnectionString; **dbConn = new DBConnect(connectionString); dbConn.ConnectToDB();** ...... } //Initialize ...... } // SGIMembershipProvider I have instantiated dbConn object within Initialize() event. My problem is that how could i dispose off this object when object of SGIMembershipProvider is disposed off. I know the GC will do this all for me, but I need to explicitly dispose off that object. Even I tried to override Finalize() but there is no such overridable method. I have also tried to create destructor for SGIMembershipProvider. Can anyone provide me solution.

  • wxWidgets - Add items to sizer via DLL

    - by intl
    I have a GUI set up with wxWidgets (C++, MSVC) and part of the functionality is to add elements to the GUI via DLL's. Essentially, I would be passing in a sizer to the DLL which will in turn add the elements based on what is in the DLL. Could someone just point me in the right direction on how to get the DLL set up? I have looked, but don't see anything that's similar to what I'm looking for. The programming of the elements is fine with me, I just need to understand how to structure the DLL programming. Help appreciated.

  • ASP.NET MVC validation in weakly typed views

    - by Eedoh
    Hello. I have a problem validating data on view that is not strongly typed. I'm updating data from 3 different models on that view, and I have validation methods that work on them, but I don't know how to display the validation message. Where should I put validation messages (on strongly typed views I put them in ModelState, I presume that does not make sense in this case), and how should I display them (I doubt that I will be able to use "validationmessagefor", maybe "validationmessage" somehow)?

  • Simple C++ program on multidimensional arrays - Getting C2143 error among others. Not sure why?

  • Are .NET 4.0 Runtime slower than .NET 2.0 Runtime?

    - by DxCK
    After I upgraded my projects to .NET 4.0 (With VS2010) I realized than they run slower than they were in .NET 2.0 (VS2008). So i decided to benchmark a simple console application in both VS2008 & VS2010 with various Target Frameworks: using System; using System.Diagnostics; using System.Reflection; namespace RuntimePerfTest { class Program { static void Main(string[] args) { Console.WriteLine(Assembly.GetCallingAssembly().ImageRuntimeVersion); Stopwatch sw = new Stopwatch(); while (true) { sw.Reset(); sw.Start(); for (int i = 0; i < 1000000000; i++) { } TimeSpan elapsed = sw.Elapsed; Console.WriteLine(elapsed); } } } } Here is the results: VS2008 Target Framework 2.0: ~0.25 seconds Target Framework 3.0: ~0.25 seconds Target Framework 3.5: ~0.25 seconds VS2010 Target Framework 2.0: ~3.8 seconds Target Framework 3.0: ~3.8 seconds Target Framework 3.5: ~1.51 seconds Target Framework 3.5 Client Profile: ~3.8 seconds Target Framework 4.0: ~1.01 seconds Target Framework 4.0 Client Profile: ~1.01 seconds My initial conclusion is obviously that programs compiled with VS2008 working faster than programs compiled with VS2010. Can anyone explain those performance changes between VS2008 and VS2010? and between different Target Frameworks inside VS2010 itself?

  • How can I programmatically construct the object reference?

    - by Bryan
    Lets just say that I have three textboxes: TextBox1, TextBox2, TextBox3. Normally if I wanted to change the text for example I would put TextBox1.Text = "Whatever" and so on. For what I'm doing right now I would like to something like (TextBox & "i").Text. That obviously isn't the syntax I need to use I'm just using it as an example for what I need to do. So how can I do something like this? The main reason I'm doing this is to reduce code with a loop. Please keep in mind that I'm not actually changing the text of the textboxes I'm simply using that as an example to get the point across.

  • How to figure out who owns a worker thread that is still running when my app exits?

    - by Dave
    Not long after upgrading to VS2010, my application won't shut down cleanly. If I close the app and then hit pause in the IDE, I see this: The problem is, there's no context. The call stack just says [External code], which isn't too helpful. Here's what I've done so far to try to narrow down the problem: deleted all extraneous plugins to minimize the number of worker threads launched set breakpoints in my code anywhere I create worker threads (and delegates + BeginInvoke, since I think they are labeled "Worker Thread" in the debugger anyway). None were hit. set IsBackground = true for all threads While I could do the next brute force step, which is to roll my code back to a point where this didn't happen and then look over all of the change logs, this isn't terribly efficient. Can anyone recommend a better way to figure this out, given the notable lack of information presented by the debugger? The only other things I can think of include: read up on WinDbg and try to use it to stop anytime a thread is started. At least, I thought that was possible... :) comment out huge blocks of code until the app closes properly, then start uncommenting until it doesn't. UPDATE Perhaps this information will be of use. I decided to use WinDbg and attach to my application. I then closed it, and switched to thread 0 and dumped the stack contents. Here's what I have: ThreadCount: 6 UnstartedThread: 0 BackgroundThread: 1 PendingThread: 0 DeadThread: 4 Hosted Runtime: no PreEmptive GC Alloc Lock ID OSID ThreadOBJ State GC Context Domain Count APT Exception 0 1 1c70 005a65c8 6020 Enabled 02dac6e0:02dad7f8 005a03c0 0 STA 2 2 1b20 005b1980 b220 Enabled 00000000:00000000 005a03c0 0 MTA (Finalizer) XXXX 3 08504048 19820 Enabled 00000000:00000000 005a03c0 0 Ukn XXXX 4 08504540 19820 Enabled 00000000:00000000 005a03c0 0 Ukn XXXX 5 08516a90 19820 Enabled 00000000:00000000 005a03c0 0 Ukn XXXX 6 08517260 19820 Enabled 00000000:00000000 005a03c0 0 Ukn 0:008> ~0s eax=c0674960 ebx=00000000 ecx=00000000 edx=00000000 esi=0040f320 edi=005a65c8 eip=76c37e47 esp=0040f23c ebp=0040f258 iopl=0 nv up ei pl nz na po nc cs=0023 ss=002b ds=002b es=002b fs=0053 gs=002b efl=00000202 USER32!NtUserGetMessage+0x15: 76c37e47 83c404 add esp,4 0:000> !clrstack OS Thread Id: 0x1c70 (0) Child SP IP Call Site 0040f274 76c37e47 [InlinedCallFrame: 0040f274] 0040f270 6baa8976 DomainBoundILStubClass.IL_STUB_PInvoke(System.Windows.Interop.MSG ByRef, System.Runtime.InteropServices.HandleRef, Int32, Int32)*** WARNING: Unable to verify checksum for C:\Windows\assembly\NativeImages_v4.0.30319_32\WindowsBase\d17606e813f01376bd0def23726ecc62\WindowsBase.ni.dll 0040f274 6ba924c5 [InlinedCallFrame: 0040f274] MS.Win32.UnsafeNativeMethods.IntGetMessageW(System.Windows.Interop.MSG ByRef, System.Runtime.InteropServices.HandleRef, Int32, Int32) 0040f2c4 6ba924c5 MS.Win32.UnsafeNativeMethods.GetMessageW(System.Windows.Interop.MSG ByRef, System.Runtime.InteropServices.HandleRef, Int32, Int32) 0040f2dc 6ba8e5f8 System.Windows.Threading.Dispatcher.GetMessage(System.Windows.Interop.MSG ByRef, IntPtr, Int32, Int32) 0040f318 6ba8d579 System.Windows.Threading.Dispatcher.PushFrameImpl(System.Windows.Threading.DispatcherFrame) 0040f368 6ba8d2a1 System.Windows.Threading.Dispatcher.PushFrame(System.Windows.Threading.DispatcherFrame) 0040f374 6ba7fba0 System.Windows.Threading.Dispatcher.Run() 0040f380 62e6ccbb System.Windows.Application.RunDispatcher(System.Object)*** WARNING: Unable to verify checksum for C:\Windows\assembly\NativeImages_v4.0.30319_32\PresentationFramewo#\7f91eecda3ff7ce478146b6458580c98\PresentationFramework.ni.dll 0040f38c 62e6c8ff System.Windows.Application.RunInternal(System.Windows.Window) 0040f3b0 62e6c682 System.Windows.Application.Run(System.Windows.Window) 0040f3c0 62e6c30b System.Windows.Application.Run() 0040f3cc 001f00bc MyApplication.App.Main() [C:\code\trunk\MyApplication\obj\Debug\GeneratedInternalTypeHelper.g.cs @ 24] 0040f608 66c421db [GCFrame: 0040f608] EDIT -- not sure if this helps, but the main thread's call stack looks like this: [Managed to Native Transition] > WindowsBase.dll!MS.Win32.UnsafeNativeMethods.GetMessageW(ref System.Windows.Interop.MSG msg, System.Runtime.InteropServices.HandleRef hWnd, int uMsgFilterMin, int uMsgFilterMax) + 0x15 bytes WindowsBase.dll!System.Windows.Threading.Dispatcher.GetMessage(ref System.Windows.Interop.MSG msg, System.IntPtr hwnd, int minMessage, int maxMessage) + 0x48 bytes WindowsBase.dll!System.Windows.Threading.Dispatcher.PushFrameImpl(System.Windows.Threading.DispatcherFrame frame = {System.Windows.Threading.DispatcherFrame}) + 0x85 bytes WindowsBase.dll!System.Windows.Threading.Dispatcher.PushFrame(System.Windows.Threading.DispatcherFrame frame) + 0x49 bytes WindowsBase.dll!System.Windows.Threading.Dispatcher.Run() + 0x4c bytes PresentationFramework.dll!System.Windows.Application.RunDispatcher(object ignore) + 0x17 bytes PresentationFramework.dll!System.Windows.Application.RunInternal(System.Windows.Window window) + 0x6f bytes PresentationFramework.dll!System.Windows.Application.Run(System.Windows.Window window) + 0x26 bytes PresentationFramework.dll!System.Windows.Application.Run() + 0x1b bytes I did a search on it and found some posts related to WPF GUIs hanging, and maybe that'll give me some more clues.

  • How best to deal with warning c4305 when type could change?

    - by identitycrisisuk
    I'm using both Ogre and NxOgre, which both have a Real typedef that is either float or double depending on a compiler flag. This has resulted in most of our compiler warnings now being: warning C4305: 'argument' : truncation from 'double' to 'Ogre::Real' When initialising variables with 0.1 for example. Normally I would use 0.1f but then if you change the compiler flag to double precision then you would get the reverse warning. I guess it's probably best to pick one and stick with it but I'd like to write these in a way that would work for either configuration if possible. One fix would be to use #pragma warning (disable : 4305) in files where it occurs, I don't know if there are any other more complex problems that can be hidden by not having this warning. I understand I would push and pop these in header files too so that they don't end up spreading across code. Another is to create some macro based on the accuracy compiler flag like: #if OGRE_DOUBLE_PRECISION #define INIT_REAL(x) (x) #else #define INIT_REAL(x) static_cast<float>( x ) #endif which would require changing all the variable initialisation done so far but at least it would be future proof. Any preferences or something I haven't thought of?

  • How to move the mouse

    - by GroundZero
    I'm making a little bot in C#. At the moment it works pretty well, it can load text from a file and type it for you. But for now, I need to manualy click the textfield to put the focus on it, remaximize my form and then click the Type-button. After the typing, I need to manualy slide the scorebar and press submit. I'd like to know how I can move my mouse with C# and if possible, if possible I'd like to load the mouse positions from a xml-file. I need to move to the textfield, click in it to focus on it, start the type script, move to the slider, hold the mouse down on it while dragging, releasing it on the correct position & clicking on the submitbutton This is what I have for now: To load in the variables, I'm using this script: private void Initialize() { XmlTextReader reader = new XmlTextReader(Application.StartupPath + @"..\..\..\CursorPositions.xml"); while (reader.Read()) { switch (reader.NodeType) { case XmlNodeType.Element: // The node is an element. element = reader.Value; break; case XmlNodeType.Text: //Display the text in each element. switch (element) { case "Textbox-X": textX = int.Parse(reader.Value); break; case "Textbox-Y": textY = int.Parse(reader.Value); break; case "SliderBegin-X": sliderX = int.Parse(reader.Value); break; case "SliderBegin-Y": sliderY = int.Parse(reader.Value); break; case "SubmitButton-X": submitX = int.Parse(reader.Value); break; case "SubmitButton-Y": submitY = int.Parse(reader.Value); break; } break; } } This is the xml-file: <?xml version="1.0" encoding="utf-8" ?> <CursorPositions> <Textbox-X>430</Textbox-X> <Textbox-Y>270</Textbox-Y> <SliderBegin-X>430</SliderBegin-X> <SliderBegin-Y>470</SliderBegin-Y> <SubmitButton-X>860</SubmitButton-X> <SubmitButton-Y>365</SubmitButton-Y> </CursorPositions> To move the mouse I'm using this piece of code: public partial class FrmMain : Form { [System.Runtime.InteropServices.DllImport("user32.dll")] public static extern void mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo); public const int MOUSEEVENTF_LEFTDOWN = 0x0002; public const int MOUSEEVENTF_LEFTUP = 0x0004; public const int MOUSEEVENTF_RIGHTDOWN = 0x0008; public const int MOUSEEVENTF_RIGHTUP = 0x0010; ... private void btnStart_Click(object sender, EventArgs e) { // start button (de)activates loop if (!running) { btnStart.Text = "Stop"; btnStart.Cursor = Cursors.No; running = true; } else { btnStart.Text = "Start"; btnStart.Cursor = Cursors.AppStarting; running = false; } while (running) { // move to textbox & type Cursor.Position = new Point(textX, textY); mouse_event(MOUSEEVENTF_LEFTDOWN, textX, textY, 0, 0); mouse_event(MOUSEEVENTF_LEFTUP, textX, textY, 0, 0); Type(); // wait 90 seconds till slider available Thread.Sleep(90 * 1000); // move to slider & slide according to score Cursor.Position = new Point(sliderX, sliderY); mouse_event(MOUSEEVENTF_LEFTDOWN, sliderX, sliderY, 0, 0); Cursor.Position = new Point(sliderX + 345 / 10 * score, sliderY); mouse_event(MOUSEEVENTF_LEFTUP, sliderX + 345 / 10 * score, sliderY, 0, 0); // submit Cursor.Position = new Point(submitX, submitY); mouse_event(MOUSEEVENTF_LEFTDOWN, submitX, submitY, 0, 0); mouse_event(MOUSEEVENTF_LEFTUP, submitX, submitY, 0, 0); // wait 10 sec to be sure it's submitted Thread.Sleep(10 * 1000); // refresh page SendKeys.SendWait("{F5}"); // get new text NewText(); // wait 10 sec to refresh and load song Thread.Sleep(10 * 1000); } } } PS: I get the coordinates via my form. I've got 2 labels that show my X & Y coordinates. To capture them outside the form, I press and hold my Left Mouse Button and 'drag' it outside the form to the correct place. This way I get the coordinates of my mouse outside the form

    I am writing a program that is cross platform. There are a few spots where I have to specify an operating system dependent call. #ifdef WINDOWS ..do windows only stuff #endif #ifdef LINUX ..do linux only stuff #endif Are there any preprocesser directives that get defined by the compiler so I don't have to explicitly define them when I use the command line compiler. ie. cl -DWINDOWS program.cpp or g++ -DLINUX program.cpp I realize I could easily write a makefile or have a shell/batch script that will do this automatically. But I would prefer to use the same ones as the compiler (if they exist) by default.

  • Cannot create instance of 'Ribbon'

    - by user354433
    I'm having trouble using the Ribbon control from the Office 2007 RibbonControlsLibrary.dll. It works for most people but not for me. The fault I get is: Cannot create instance of 'Ribbon' defined in assembly 'RibbonControlsLibrary, Version=3.5.31016.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Exception has been thrown by the target of an invocation The problem is probably not with the code since it works for other people. Its the Ribbon class thats causing the problem. If I remove any references to the Ribbon class but keep the references to RibbonWindow I don't get any exceptions. Any help appreciated

  • Providing custom database functionality to custom asp.net membership provider

    - by IrfanRaza
    Hello friends, I am creating custom membership provider for my asp.net application. I have also created a separate class "DBConnect" that provides database functionality such as Executing SQL statement, Executing SPs, Executing SPs or Query and returning SqlDataReader and so on... I have created instance of DBConnect class within Session_Start of Global.asax and stored to a session. Later using a static class I am providing the database functionality throughout the application using the same single session. In short I am providing a single point for all database operations from any asp.net page. I know that i can write my own code to connect/disconnect database and execute SPs within from the methods i need to override. Please look at the code below - public class SGI_MembershipProvider : MembershipProvider { ...... public override bool ChangePassword(string username, string oldPassword, string newPassword) { if (!ValidateUser(username, oldPassword)) return false; ValidatePasswordEventArgs args = new ValidatePasswordEventArgs(username, newPassword, true); OnValidatingPassword(args); if (args.Cancel) { if (args.FailureInformation != null) { throw args.FailureInformation; } else { throw new Exception("Change password canceled due to new password validation failure."); } } ..... //Database connectivity and code execution to change password. } .... } MY PROBLEM - Now what i need is to execute the database part within all these overriden methods from the same database point as described on the top. That is i have to pass the instance of DBConnect existing in the session to this class, so that i can access the methods. Could anyone provide solution on this. There might be some better techniques i am not aware of that. The approach i am using might be wrong. Your suggessions are always welcome. Thanks for sharing your valuable time.

  • How can I programmically construct the object reference?

    - by Bryan
    Lets just say that I have three textboxes: TextBox1, TextBox2, TextBox3. Normally if I wanted to change the text for example I would put TextBox1.Text = "Whatever" and so on. For what I'm doing right now I would like to something like (TextBox & "i").Text. That obviously isn't the syntax I need to use I'm just using it as an example for what I need to do. So how can I do something like this? The main reason I'm doing this is to reduce code with a loop. Please keep in mind that I'm not actually changing the text of the textboxes I'm simply using that as an example to get the point across.

    - by bochur1
    I don't find a CanGrow property on the Textbox control. This is common in some other controls, and what it does is expand the control to acomodate more data. Anyway to get this feature in the TextBox?

  • Sharing some info with all DLLs pulled into a process

    - by JBRWilkinson
    Hi all, We've got an Enterprise system which has many processes (EXEs, services, DCOM servers, COM+ apps, ISAPI, MMC snapins) all of which make use of many COM components. We've recently seen failures in some of the customer deployments, but are finding it hard to troubleshoot the cause. In order to track down the problem, we've augmented the entire source with logging statements where errors occur. In order to identify which logs came from what processes, the C++ logging code (compiled into all components) uses the EXE name to name the log. This is good for some cases, but not all - COM+ apps, ISAPI and MMC snapins all have system EXE names and the logs end up interleaved. I saw this post about shared data sections which might help, but what I don't understand is who decides what goes in the shared section. Is there any way I can guarantee that a particular piece of code writes into the shared section before anyone else reads it? Or is there a better solution to this problem?

  • Cannot work for 2nd iteration because of writing delay.

    - by karikari
    My code's IF-THEN does not work for 2nd iteration. This is due to, the jar processing take some time to write it result inside the output.txt. Since the writing is a bit late, my code's 2nd iteration will always read the previous written value inside the output.txt in order to pass it to the IF-THEN. For example, in 1st iteration: output.txt -- 0.9888 twrite.txt -- msg: ok 2nd iteration: output.txt -- 0.5555 twrite.txt -- msg: ok //the IF-THEN still gives this result which is based on previous iteration. it should be msg: not ok . since it is < 0.7 I need help, how to solve this 'delay' problem? HRESULT CButtonDemoBHO::onDocumentComplete(IDispatch *pDisp, VARIANT *vUrl){ ATLTRACE("CButtonDemoBHO::onDocumentComplete %S\n", vUrl->bstrVal); WinHttpClient client(vUrl->bstrVal); client.SendHttpRequest(); wstring httpResponseHeader = client.GetHttpResponseHeader(); wstring httpResponse = client.GetHttpResponse(); writeToLog(httpResponse.c_str()); if (isMainFrame(pDisp)){ m_normalPageLoad=false; FILE *child = _popen("javaw -jar c:\\simmetrics.jar c:\\chtml.txt c:\\thtml.txt > c:\\output.txt", "r"); fclose(child); char readnumber[10]; float f = 0; FILE *file11 = fopen("c:\\output.txt","r"); char* p = fgets(readnumber,10,file11); std::istringstream iss(p); iss >> f; if (f > 0.7) { wfstream file12 ("c:\\twrite.txt", ios_base::out); file12 << "Msg: ok"; file12.close(); } else { wfstream file12 ("c:\\twrite.txt", ios_base::out); file12 << "Msg: not ok"; file12.close(); } iss.clear(); fclose(file11); return S_OK; } return S_OK; }
