  • Inline HTML Syntax for Helpers in ASP.NET MVC

    - by kouPhax
    I have a class that extends the HtmlHelper in MVC and allows me to use the builder pattern to construct special output e.g. <%= Html.FieldBuilder<MyModel>(builder => { builder.Field(model => model.PropertyOne); builder.Field(model => model.PropertyTwo); builder.Field(model => model.PropertyThree); }) %> Which outputs some application specific HTML, lets just say, <ul> <li>PropertyOne: 12</li> <li>PropertyTwo: Test</li> <li>PropertyThree: true</li> </ul> What I would like to do, however, is add a new builder methid for defining some inline HTML without having to store is as a string. E.g. I'd like to do this. <% Html.FieldBuilder<MyModel>(builder => { builder.Field(model => model.PropertyOne); builder.Field(model => model.PropertyTwo); builder.ActionField(model => %> Generated: <%=DateTime.Now.ToShortDate()%> (<a href="#">Refresh</a>) <%); }).Render(); %> and generate this <ul> <li>PropertyOne: 12</li> <li>PropertyTwo: Test</li> <li>Generated: 29/12/2008 <a href="#">Refresh</a></li> </ul> Essentially an ActionExpression that accepts a block of HTML. However to do this it seems I need to execute the expression but point the execution of the block to my own StringWriter and I am not sure how to do this. Can anyone advise?

  • Deriving from a component and implementing IDisposable properly

    - by PaulH
    I have a Visual Studio 2008 C# .NET 2.0 CF project with an abstract class derived from Component. From that class, I derive several concrete classes (as in my example below). But, when I go to exit my Form, though the Form's Dispose() member is called and components.Dispose() is called, my components are never disposed. Can anybody suggest how I can fix this design? public abstract class SomeDisposableComponentBase : Component { private System.ComponentModel.IContainer components; protected SomeDisposableComponentBase() { Initializecomponent(); } protected SomeDisposableComponentBase(IContainer container) { container.Add(this); Initializecomponent(); } private void InitializeComponent() { components = new System.ComponentModel.Container(); } protected abstract void Foo(); #region IDisposable Members bool disposed_; /// Warning 60 CA1063 : Microsoft.Design : Ensure that 'SomeDisposableComponentBase.Dispose()' is declared as public and sealed.* public void Dispose() { // never called Dispose(true); GC.SuppressFinalize(this); } protected virtual void Dispose(bool disposing) { // never called if (!disposed_) { if (disposing && (components != null)) { components.Dispose(); } disposed_ = true; } base.Dispose(disposing); } #endregion } public SomeDisposableComponent : SomeDisposableComponentBase { public SomeDisposableComponent() : base() { } public SomeDisposableComponent(IContainer container) : base(container) { } protected override void Foo() { // Do something... } protected override void Dispose(bool disposing) { // never called base.Dispose(disposing); } } public partial class my_form : Form { private SomeDisposableComponentBase d_; public my_form() { InitializeComponent(); if (null == components) components = new System.ComponentModel.Container(); d_ = new SomeDisposableComponent(components); } /// exit button clicked private void Exit_Click(object sender, EventArgs e) { this.Close(); } /// from the my_form.designer.cs protected override void Dispose(bool disposing) { if (disposing && (components != null)) { // this function is executed as expected when the form is closed components.Dispose(); } base.Dispose(disposing); } } *I note that FX-Cop is giving me a hint here. But, if I try to declare that function as sealed, I get the error: error CS0238: 'SomeDisposableComponentBase.Dispose()' cannot be sealed because it is not an override Declaring that function an override leads to: 'SomeDisposableComponentBase.Dispose()': cannot override inherited member 'System.ComponentModel.Component.Dispose()' because it is not marked virtual, abstract, or override Thanks, PaulH

  • Can I import contacts from an Exchange 2003 EDB file for a single user?

    - by Drarok
    We have recently had to reinstall a very unhappy Exchange 2003 server for a client, and whilst rebuilding their server we moved them onto a temporary one. During the course of all this, ExMerge was used due to Windows being so broken that none of the backup software could run. As a number of the user mailboxes were way over 2GB, we had to do date ranges of a few months at a time to avoid ExMerge's 2GB limit. We went back as far as 2006, as the files produced by ExMerge seemed empty that far back. Unfortunately, one of the users has reported that around 2 3rds of their contacts are missing, and that pre-2006 sounds about right for the missing items. Is there any way I can mount the old EDB file into Exchange, or otherwise read their contacts into a usable format? The server is running Windows Server 2003 SBS R2 (SP2), and Exchance 2003 (SP2, I think).

  • hyper-v server 2003 instance using internet connection sharing disconnects remote desktop to hyper-v host

    - by Joseph Southwell
    I have a windows server 2003 R2 instance running in a hyper-v instance on windows 8. I have setup an internal switch that uses internet connection sharing to get out to the internet. It works fine except for when I try to do windows update on the server 2003 instance it disconnects my remote desktop session to the windows 8 hyper-v host. When I reconnect it says windows update failed. I know that sounds crazy but I have tested it over and over again. If I change the instance to use my external switch (I have an external switch defined on another network adapter) windows update works fine.

  • Flatten date range memberships retaining only the highest priority membership (TRANSACT-SQL)

    - by shadowranger
    Problem statement: A table contains an item_id, a category_id and a date range (begin_date and end_date). No item may be in more than one category on any given date (in general; during daily rebuilding it can be in an invalid state temporarily). By default, all items are added (and re-added if removed) to a category (derived from outside data) automatically on a daily basis, and their membership in that category matches the lifespan of the item (items have their own begin and end date, and usually spend their entire lives in the same category, which is why this matches). For items in category X, it is occasionally desirable to override the default category by adding them to category Y. Membership in category Y could entirely replace membership in category X (that is, the begin and end dates for membership in category Y would match the begin and end dates of the item itself), or it could override it for an arbitrary period of time (at the beginning, middle or end the item's lifespan, possibly overriding for short periods at multiple times). Membership in category Y is not renewed automatically and additions to that category is done by manual data entry. Every day, when category X is rebuilt, we get an overlap, where any item in category Y will now be in category X as well (which is forbidden, as noted previously). Goal: After each repopulation of category X (which is done in a rather complicated and fragile manner, and ideally would be left alone), I'm trying to find an efficient means of writing a stored procedure that: Identifies the overlaps Changes existing entries, adds new ones where necessary (such as in the case where an item starts in category X, switches to category Y, then eventually switches back to category X before ending), or removes entries (when an item is in category Y for its entire life) such that every item remains in category Y (and only Y) where specified, while category X membership is maintained when not overridden by category Y. Does not affect memberships of categories A, B, C, Z, etc., which do not have override categories and are built separately, by completely different rules. Note: It can be assumed that X membership covers the entire lifespan of the item before this procedure is called, so it is unnecessary to query any data outside this table. Bonus credit: If for some reason there are two adjacent or overlapping memberships in for the same item in category Y, stitching them together into a single entry is appreciated, but not necessary. Example: item_id category_id begin_date end_date 1 X 20080101 20090628 1 Y 20090101 20090131 1 Y 20090601 20090628 2 X 20080201 20080731 2 Y 20080201 20080731 Should become: item_id category_id begin_date end_date 1 X 20080101 20081231 1 Y 20090101 20090131 1 X 20090201 20090531 1 Y 20090601 20090628 2 Y 20080201 20080731 If it matters, this needs to work on SQL Server 2005 and SQL Server 2008

  • Excel trendline accuracy

    - by Rook
    This is a problem I have every once in a while, and it annoys me tremendously, beacuse I have always to recheck every trendline I get. An example: r L (mm) 30,00 97,0 60,00 103,2 90,00 106,0 110,00 101,0 125,00 88,0 140,00 62,0 148,00 36,7 152,50 17,0 Upon drawing a trendline (using 3rd order polynomial regression type) with r on the x axis, and L on the y one, Excel will give the formula y = -0,0002x³ + 0,0341x² - 1,8979x + 128,73 with R² = 0,994. If I interpolate values using that formula for the same values of r as the ones the formula was derived from, I get r y (mm) 30,00 97,083 60,00 94,416 90,00 88,329 110,00 66,371 125,00 33,68 140,00 -17,416 148,00 -53,5912 152,50 -76,97725 which are quite different? Why does this happen? What is the reason for it?

  • "Access violation reading location" while accessing a global vector..

    - by djzmo
    Hello there, -- First of all, I don't know whether the vector can be called as a "global vector" if I declared it under a namespace, but not in a class or function. -- I'm now writing a simple Irrlicht (http://irrlicht.sourceforge.net) wrapper for my game to make things simpler and easier, but recently I got an "Access violation reading location" error when trying to push_back a vector declared in the global scope. Here is my code so far: irrwrap.cpp: namespace irrw { //......... IrrlichtDevice *device; IVideoDriver *driver; irr::core::array<irr::video::ITexture*> TextureCollector; vector<int> TextureConnector; //......... } //.............. void irrInit(int iGraphicsDriver, int iWindowWidth, int iWindowHeight, int iScreenDepth, bool bFullScreen) { E_DRIVER_TYPE drvT; if(iGraphicsDriver == GD_SOFTWARE) drvT = EDT_SOFTWARE; else if(iGraphicsDriver == GD_D3D8) drvT = EDT_DIRECT3D8; else if(iGraphicsDriver == GD_D3D9) drvT = EDT_DIRECT3D9; else if(iGraphicsDriver == GD_OPENGL) drvT = EDT_OPENGL; //.............. irrw::device = createDevice(drvT, dimension2d<u32>(iWindowWidth, iWindowHeight), iScreenDepth, bFullScreen); irrw::driver = irrw::device->getVideoDriver(); //.................. } void irrLoadImage(irr::core::stringc szFileName, int iID, int iTextureFlag) { //........ irrw::TextureCollector.push_back(irrw::driver->getTexture(szFileName)); // the call stack pointed to this line irrw::TextureConnector.push_back(iID); } main.cpp: //......... INT WINAPI WinMain(HINSTANCE hInst, HINSTANCE, LPSTR strCmdLine, INT) { //......... irrInit(GD_OPENGL, 800, 600, 16, false); irrLoadImage("picture.jpg", 100, 1); //......... } and the error: Unhandled exception at 0x692804d6 in Game.exe: 0xC0000005: Access violation reading location 0x00000558. Now I really got no idea on how to fix the problem. Any kind of help would be appreciated :) Here are some prototypes: virtual ITexture* getTexture(const io::path& filename) = 0; typedef core::string<fschar_t> path; // under 'io' namespace typedef char fschar_t; typedef string<c8> stringc; typedef char c8; Just FYI, I am using MSVC++ 2008 EE.

  • How do I set "MaxPermSize" for Atlassian Fisheye/Crucible running as service on Win2k3?

    - by Jeremy
    I have been trying to setup Atlassian Fisheye/Crucible as a service on Win 2K3 R2 for two weeks. I keep getting various "java.lang.OutOfMemoryError: PermGen space" errors, which crash Fisheye and force me to restart the service. I've followed the example on the Atlassian support site to configure MaxPermSize within the service wrapper. However, when I check SysInfo inside the Fisheye Admin pages and the debug log, I don't see any confirmation. The Java Heap info is in both places, so I'd expect the MaxPermSize setting to show up in both places. The error is persisting and Atlassian support has been little help. I appreciate any help.

  • What are the Options for Storing Hierarchical Data in a Relational Database?

    - by orangepips
    Good Overviews One more Nested Intervals vs. Adjacency List comparison: the best comparison of Adjacency List, Materialized Path, Nested Set and Nested Interval I've found. Models for hierarchical data: slides with good explanations of tradeoffs and example usage Representing hierarchies in MySQL: very good overview of Nested Set in particular Hierarchical data in RDBMSs: most comprehensive and well organized set of links I've seen, but not much in the way on explanation Options Ones I am aware of and general features: Adjacency List: Columns: ID, ParentID Easy to implement. Cheap node moves, inserts, and deletes. Expensive to find level (can store as a computed column), ancestry & descendants (Bridge Hierarchy combined with level column can solve), path (Lineage Column can solve). Use Common Table Expressions in those databases that support them to traverse. Nested Set (a.k.a Modified Preorder Tree Traversal) First described by Joe Celko - covered in depth in his book Trees and Hierarchies in SQL for Smarties Columns: Left, Right Cheap level, ancestry, descendants Compared to Adjacency List, moves, inserts, deletes more expensive. Requires a specific sort order (e.g. created). So sorting all descendants in a different order requires additional work. Nested Intervals Combination of Nested Sets and Materialized Path where left/right columns are floating point decimals instead of integers and encode the path information. Bridge Table (a.k.a. Closure Table: some good ideas about how to use triggers for maintaining this approach) Columns: ancestor, descendant Stands apart from table it describes. Can include some nodes in more than one hierarchy. Cheap ancestry and descendants (albeit not in what order) For complete knowledge of a hierarchy needs to be combined with another option. Flat Table A modification of the Adjacency List that adds a Level and Rank (e.g. ordering) column to each record. Expensive move and delete Cheap ancestry and descendants Good Use: threaded discussion - forums / blog comments Lineage Column (a.k.a. Materialized Path, Path Enumeration) Column: lineage (e.g. /parent/child/grandchild/etc...) Limit to how deep the hierarchy can be. Descendants cheap (e.g. LEFT(lineage, #) = '/enumerated/path') Ancestry tricky (database specific queries) Database Specific Notes MySQL Use session variables for Adjacency List Oracle Use CONNECT BY to traverse Adjacency Lists PostgreSQL ltree datatype for Materialized Path SQL Server General summary 2008 offers HierarchyId data type appears to help with Lineage Column approach and expand the depth that can be represented.

  • Map the 'Domain Admins' group into the local Ubuntu 'admin' group

    - by Miquella
    I have configured an Ubuntu 10.04 box to connect to our domain (Windows 2003 R2) using Likewise-Open. All the users can authenticate as expected. However, the domain administrators do not have administrative privileges to the machine. After working at this for a few hours, I've determined what I think may be a solution: if I map the 'Domain Admins' group from the Active Directory into the local 'admin' group, the users should get the appropriate permissions. But I have no idea how to do that. Does this even sound like the correct approach? A similar question was asked on StackOverflow and then migrated here. But it was never answered as it was recommended to be asked here instead. Thanks in advance!

  • Permit Communicator to display an web site with an ActiveX control in Vista or Windows 7

    - by dmo
    I have a UCMA service that sends a URL to load in a communicator extensibility tab as mentioned here: http://blogs.claritycon.com/blogs/michael_greenlee/archive/2009/02/19/context-windows-in-communicator-using-ucma-v2-0.aspx http://social.msdn.microsoft.com/Forums/en-US/ucclientsdk/thread/4406e412-01f1-466f-a593-3b83652dcdb1 This works fine with Office Communicator 2007 R2 for most trusted links, and on Windows XP and 2003 it works fine with a page with an ActiveX control. However, the ActiveX content is not displayed in Vista or Window 7. I've tried relaxing the security settings to no avail. Any suggestions or guidance would be much appreciated.

  • Access violation when running native C++ application that uses a /clr built DLL

    - by doobop
    I'm reorganzing a legacy mixed (managed and unmanaged DLLs) application so that the main application segment is unmanaged MFC and that will call a C++ DLL compiled with /clr flag that will bridge the communication between the managed (C# DLLs) and unmanaged code. Unfortuantely, my changed have resulted in an Access violation that occurs before the application InitInstance() is called. This makes it very difficult to debug. The only information I get is the following stack trace. > 64006108() ntdll.dll!_ZwCreateMutant@16() + 0xc bytes kernel32.dll!_CreateMutexW@12() + 0x7a bytes So, here are some sceanrios I've tried. - Turned on Exceptions-Win32 Exceptions-c0000005 Access Violation to break when Thrown. Still the most detail I get is from the above stack trace. I've tried the application with F10, but it fails before any breakpoints are hit and fails with the above stack trace. - I've stubbed out the bridge DLL so that it only has one method that returns a bool and that method is coded to just return false (no C# code called). bool DllPassthrough::IsFailed() { return false; } If the stubbed out DLL is compiled with the /clr flag, the application fails. If it is compiled without the /clr flag, the application runs. - I've created a stub MFC application using the Visual Studio wizard for multidocument applications and call DllPassthrough::IsFailed(). This succeeds even with the /clr flag used to compile the DLL. - I've tried doing a manual LoadLibrary on winmm.lib as outlined in the following note Access violation when using c++/cli. The application still fails. So, my questions are how to solve the problem? Any hints, strategies, or previous incidents. And, failing that, how can I get more information on what code segment or library is causing the access exception? If I try more involved workarounds like doing LoadLibrary calls, I'd like to narrow it to the failing libraries. Thanks. BTW, we are using Visual Studio 2008 and the project is being built against the .NET 2.0 framework for the managed sections.

  • Office Communicator starts up automatically even though I disabled it

    - by chiccodoro
    The title says it all: I am trying desperately to keep OCS from starting automatically when I log in to Windows. The first and only thing I did was unchecking the "Automatically start Communicator when I log on to Windows" option. I can verify that it is still disabled, but OCS ignores that and starts up as soon as I log on to Windows. There is no OCS in the "Startup" folder, and the registry setting "AutoRunWhenLogonToWindows" at HKEY_CURRENT_USER\Software\Microsoft\Communicator is set to 0x00000000. I am using Office Communicator 2007 R2 on a Windows 7 with Microsoft Office 2010.

  • Java Deployment with automatic updates (without user confirmation)

    - by Svanste
    Here in our company our users use 1 Java application which is updated every monday and always needs the latest java update. We install Java on Clients through SCCM 2012 R2. I already know how to this, the only thing i can't figure out is how to automatically update Java on computers. This has to be silent, so we don't want users to get a pop up asking if they want to install the latest the Java update. We want Java to autoupdate when users logon on monday morning, with no possibility to cancel it. (At least no obvious way to cancel it, so no cancel button or anything basic) Been searching on google for a while now but most scenario's involve NOT wanting autoupdate.

  • ReadFile doesn't work asynchronously on Win7 and Win2k8

    - by f0b0s
    According to MSDN ReadFile can read data 2 different ways: synchronously and asynchronously. I need the second one. The folowing code demonstrates usage with OVERLAPPED struct: #include <windows.h> #include <stdio.h> #include <time.h> void Read() { HANDLE hFile = CreateFileA("c:\\1.avi", GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_FLAG_OVERLAPPED, NULL); if ( hFile == INVALID_HANDLE_VALUE ) { printf("Failed to open the file\n"); return; } int dataSize = 256 * 1024 * 1024; char* data = (char*)malloc(dataSize); memset(data, 0xFF, dataSize); OVERLAPPED overlapped; memset(&overlapped, 0, sizeof(overlapped)); printf("reading: %d\n", time(NULL)); BOOL result = ReadFile(hFile, data, dataSize, NULL, &overlapped); printf("sent: %d\n", time(NULL)); DWORD bytesRead; result = GetOverlappedResult(hFile, &overlapped, &bytesRead, TRUE); // wait until completion - returns immediately printf("done: %d\n", time(NULL)); CloseHandle(hFile); } int main() { Read(); } On Windows XP output is: reading: 1296651896 sent: 1296651896 done: 1296651899 It means that ReadFile didn't block and returned imediatly at the same second, whereas reading process continued for 3 seconds. It is normal async reading. But on windows 7 and windows 2008 I get following results: reading: 1296661205 sent: 1296661209 done: 1296661209. It is a behavior of sync reading. MSDN says that async ReadFile sometimes can behave as sync (when the file is compressed or encrypted for example). But the return value in this situation should be TRUE and GetLastError() == NO_ERROR. On Windows 7 I get FALSE and GetLastError() == ERROR_IO_PENDING. So WinApi tells me that it is an async call, but when I look at the test I see that it is not! I'm not the only one who found this "bug": read the comment on ReadFile MSDN page. So what's the solution? Does anybody know? It is been 14 months after Denis found this strange behavior.

  • How to check if a server runs in pressing mode

    - by Ice
    Hi there, Layout: i have at customer side a server (win2003 R2 SP2 standard edition 32-bit) with a sql-server 2005 and some databases. This system starts with the /3GB-Switch. The system reports 3.25 GB RAM and taskmanager reports the process of sqlserver.exe with 2758255 K as the process with the highest consumption. The OS separates RAM for applications and for itself, normaly 50:50. But here we have the /3GB-Switch aktivated and i think the part for the applications is more than 50% of RAM. Knowledge (or better not knowledge): Somebody told me that if the OS runs out of memory within his part of RAM, the server runs into pressing mode. Questions: What is this pressing mode? Is pressing mode possible at all in this szenario? What should be done to get more performance out of this sql-server, beside optimizing the database and all this stuff.

  • Third-party Information Screen Opening Blank

    - by Jacob
    I'm working with a client who is trying to use our software, which accesses information (sends & receives) from a third-party website. When this client tries to access these pages, a window opens, as expected, but is completely blank and no error message is received. This is the first time I've seen this with many other clients successfully using this product, which leads me to believe that it has something to do with the settings on the computer somewhere, but cannot figure out what might be happening. Windows Server 2003 R2, Standard Edition, Service Pack 2. Firewall is already off. Tried AVG on & temporarily disabled.

  • Dynamically loading modules in Python (+ multi processing question)

    - by morpheous
    I am writing a Python package which reads the list of modules (along with ancillary data) from a configuration file. I then want to iterate through each of the dynamically loaded modules and invoke a do_work() function in it which will spawn a new process, so that the code runs ASYNCHRONOUSLY in a separate process. At the moment, I am importing the list of all known modules at the beginning of my main script - this is a nasty hack I feel, and is not very flexible, as well as being a maintenance pain. This is the function that spawns the processes. I will like to modify it to dynamically load the module when it is encountered. The key in the dictionary is the name of the module containing the code: def do_work(work_info): for (worker, dataset) in work_info.items(): #import the module defined by variable worker here... # [Edit] NOT using threads anymore, want to spawn processes asynchronously here... #t = threading.Thread(target=worker.do_work, args=[dataset]) # I'll NOT dameonize since spawned children need to clean up on shutdown # Since the threads will be holding resources #t.daemon = True #t.start() Question 1 When I call the function in my script (as written above), I get the following error: AttributeError: 'str' object has no attribute 'do_work' Which makes sense, since the dictionary key is a string (name of the module to be imported). When I add the statement: import worker before spawning the thread, I get the error: ImportError: No module named worker This is strange, since the variable name rather than the value it holds are being used - when I print the variable, I get the value (as I expect) whats going on? Question 2 As I mentioned in the comments section, I realize that the do_work() function written in the spawned children needs to cleanup after itself. My understanding is to write a clean_up function that is called when do_work() has completed successfully, or an unhandled exception is caught - is there anything more I need to do to ensure resources don't leak or leave the OS in an unstable state? Question 3 If I comment out the t.daemon flag statement, will the code stil run ASYNCHRONOUSLY?. The work carried out by the spawned children are pretty intensive, and I don't want to have to be waiting for one child to finish before spawning another child. BTW, I am aware that threading in Python is in reality, a kind of time sharing/slicing - thats ok Lastly is there a better (more Pythonic) way of doing what I'm trying to do? [Edit] After reading a little more about Pythons GIL and the threading (ahem - hack) in Python, I think its best to use separate processes instead (at least IIUC, the script can take advantage of multiple processes if they are available), so I will be spawning new processes instead of threads. I have some sample code for spawning processes, but it is a bit trivial (using lambad functions). I would like to know how to expand it, so that it can deal with running functions in a loaded module (like I am doing above). This is a snippet of what I have: def do_mp_bench(): q = mp.Queue() # Not only thread safe, but "process safe" p1 = mp.Process(target=lambda: q.put(sum(range(10000000)))) p2 = mp.Process(target=lambda: q.put(sum(range(10000000)))) p1.start() p2.start() r1 = q.get() r2 = q.get() return r1 + r2 How may I modify this to process a dictionary of modules and run a do_work() function in each loaded module in a new process?
