  • Trying to Add Insert Row to Footer in GridView ASP.net

    - by chillconsulting
    I'm trying to give the user the ability to create a new record from the footer row and my event handler doesn't seem to be working... or maybe I'm going at this all wrong.

  • Two-way databinding of a custom templated asp.net control

    - by Jason
    I hate long code snippets and I'm sorry about this one, but it turns out that this asp.net stuff can't get much shorter and it's so specific that I haven't been able to generalize it without a full code listing. I just want simple two-way, declarative, edit-only databinding to a single instance of an object. Not a list of objects of a type with a bunch of NotImplementedExceptions for Add, Delete, and Select, but just a single view-state persisted object. This is certainly something that can be done but I've struggled with an implementation for years. This newest, closest implementation was inspired by this article from 4-Guys-From-Rolla. Unfortunately, after implementing, I'm getting the following error and I don't know what I'm missing: System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. If I don't use Bind(), and only use Eval() functionality, it works. In that way, the error is especially confusing. Update: Actually, using Eval() does NOT work, but using <%# Container.SampleString %> works. However, Eval("SampleString") gives the same error. That leads me back to this article I found earlier but had discarded. Now I believe it might be related, though I haven't cracked it yet ... Here's the simplified codeset that still produces the error: using System.ComponentModel; namespace System.Web.UI.WebControls.Special { public class SampleFormData { public string SampleString = "Sample String Data"; public int SampleInt = -1; } [ToolboxItem(false)] public class SampleSpecificFormDataContainer : DataBoundControl, INamingContainer { SampleSpecificEntryForm entryForm; internal SampleSpecificEntryForm EntryForm { get { return entryForm; } } [Bindable(true), Category("Data")] public string SampleString { get { return entryForm.FormData.SampleString; } set { entryForm.FormData.SampleString = value; } } [Bindable(true), Category("Data")] public int SampleInt { get { return entryForm.FormData.SampleInt; } set { entryForm.FormData.SampleInt = value; } } internal SampleSpecificFormDataContainer(SampleSpecificEntryForm entryForm) { this.entryForm = entryForm; } } public class SampleSpecificEntryForm : WebControl, INamingContainer { #region Template private IBindableTemplate formTemplate = null; [Browsable(false), DefaultValue(null), TemplateContainer(typeof(SampleSpecificFormDataContainer), ComponentModel.BindingDirection.TwoWay), PersistenceMode(PersistenceMode.InnerProperty)] public virtual IBindableTemplate FormTemplate { get { return formTemplate; } set { formTemplate = value; } } #endregion #region Viewstate SampleFormData FormDataVS { get { return (ViewState["FormData"] as SampleFormData) ?? new SampleFormData(); } set { ViewState["FormData"] = value; SaveViewState(); } } #endregion public override ControlCollection Controls { get { EnsureChildControls(); return base.Controls; } } private SampleSpecificFormDataContainer formDataContainer = null; [Browsable(false), DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] public SampleSpecificFormDataContainer FormDataContainer { get { EnsureChildControls(); return formDataContainer; } } [Bindable(true), Browsable(false)] public SampleFormData FormData { get { return FormDataVS; } set { FormDataVS = value; } } protected override void CreateChildControls() { if (!this.ChildControlsCreated) { Controls.Clear(); formDataContainer = new SampleSpecificFormDataContainer(this); Controls.Add(formDataContainer); FormTemplate.InstantiateIn(formDataContainer); this.ChildControlsCreated = true; } } public override void DataBind() { CreateChildControls(); base.DataBind(); } } } With an ASP.NET page the following: <%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default2.aspx.cs" Inherits="EntryFormTest._Default2" EnableEventValidation="false" %> <%@ Register Assembly="EntryForm" Namespace="System.Web.UI.WebControls.Special" TagPrefix="cc1" %> <asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"> </asp:Content> <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> <h2> Welcome to ASP.NET! </h2> <cc1:SampleSpecificEntryForm ID="EntryForm1" runat="server"> <FormTemplate> <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("SampleString") %>'></asp:TextBox><br /> <h3>(<%# Container.SampleString %>)</h3><br /> <asp:Button ID="Button1" runat="server" Text="Button" /> </FormTemplate> </cc1:SampleSpecificEntryForm> </asp:Content> Default2.aspx.cs using System; namespace EntryFormTest { public partial class _Default2 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { EntryForm1.DataBind(); } } } Thanks for any help!

  • Approaches for generic, compile-time safe lazy-load methods

    - by Aaronaught
    Suppose I have created a wrapper class like the following: public class Foo : IFoo { private readonly IFoo innerFoo; public Foo(IFoo innerFoo) { this.innerFoo = innerFoo; } public int? Bar { get; set; } public int? Baz { get; set; } } The idea here is that the innerFoo might wrap data-access methods or something similarly expensive, and I only want its GetBar and GetBaz methods to be invoked once. So I want to create another wrapper around it, which will save the values obtained on the first run. It's simple enough to do this, of course: int IFoo.GetBar() { if ((Bar == null) && (innerFoo != null)) Bar = innerFoo.GetBar(); return Bar ?? 0; } int IFoo.GetBaz() { if ((Baz == null) && (innerFoo != null)) Baz = innerFoo.GetBaz(); return Baz ?? 0; } But it gets pretty repetitive if I'm doing this with 10 different properties and 30 different wrappers. So I figured, hey, let's make this generic: T LazyLoad<T>(ref T prop, Func<IFoo, T> loader) { if ((prop == null) && (innerFoo != null)) prop = loader(innerFoo); return prop; } Which almost gets me where I want, but not quite, because you can't ref an auto-property (or any property at all). In other words, I can't write this: int IFoo.GetBar() { return LazyLoad(ref Bar, f => f.GetBar()); // <--- Won't compile } Instead, I'd have to change Bar to have an explicit backing field and write explicit getters and setters. Which is fine, except for the fact that I end up writing even more redundant code than I was writing in the first place. Then I considered the possibility of using expression trees: T LazyLoad<T>(Expression<Func<T>> propExpr, Func<IFoo, T> loader) { var memberExpression = propExpr.Body as MemberExpression; if (memberExpression != null) { // Use Reflection to inspect/set the property } } This plays nice with refactoring - it'll work great if I do this: return LazyLoad(f => f.Bar, f => f.GetBar()); But it's not actually safe, because someone less clever (i.e. myself in 3 days from now when I inevitably forget how this is implemented internally) could decide to write this instead: return LazyLoad(f => 3, f => f.GetBar()); Which is either going to crash or result in unexpected/undefined behaviour, depending on how defensively I write the LazyLoad method. So I don't really like this approach either, because it leads to the possibility of runtime errors which would have been prevented in the first attempt. It also relies on Reflection, which feels a little dirty here, even though this code is admittedly not performance-sensitive. Now I could also decide to go all-out and use DynamicProxy to do method interception and not have to write any code, and in fact I already do this in some applications. But this code is residing in a core library which many other assemblies depend on, and it seems horribly wrong to be introducing this kind of complexity at such a low level. Separating the interceptor-based implementation from the IFoo interface by putting it into its own assembly doesn't really help; the fact is that this very class is still going to be used all over the place, must be used, so this isn't one of those problems that could be trivially solved with a little DI magic. The last option I've already thought of would be to have a method like: T LazyLoad<T>(Func<T> getter, Action<T> setter, Func<IFoo, T> loader) { ... } This option is very "meh" as well - it avoids Reflection but is still error-prone, and it doesn't really reduce the repetition that much. It's almost as bad as having to write explicit getters and setters for each property. Maybe I'm just being incredibly nit-picky, but this application is still in its early stages, and it's going to grow substantially over time, and I really want to keep the code squeaky-clean. Bottom line: I'm at an impasse, looking for other ideas. Question: Is there any way to clean up the lazy-loading code at the top, such that the implementation will: Guarantee compile-time safety, like the ref version; Actually reduce the amount of code repetition, like the Expression version; and Not take on any significant additional dependencies? In other words, is there a way to do this just using regular C# language features and possibly a few small helper classes? Or am I just going to have to accept that there's a trade-off here and strike one of the above requirements from the list?

  • Printing an array in a method, from a different class?

    - by O.Lodhi
    Hello All, I'm a fairly inexperienced programmer, and i'm currently working on a Console Application project. It's basically a little 'mathematics game'; the application generates two random numbers, that have either been added, subtracted, multiplied or divided against each other randomly. The answer is shown on screen and the user has to pick from the menu which is the right mathematical operator, once the correct answer is picked the application then displays on screen how long it took for the user in milliseconds to input the correct answer. Now I want to save the times of the players in an array that can be called up later with all the scores. I need to include a method in this programme and I figured a method to save the times into an array would be suitable. I seem to have stumbled across a little problem though. I'm not quite sure what's wrong: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Mathgame { class Program { } class arrayclass { public static void saveInArray(int duration) { int[] TopTenScores = {000,1000,2000,3000,4000,5000,6000,7000,8000,9000}; if (duration < 1000) { duration = TopTenScores[000]; } else if ((duration >= 1000) && (duration <= 1999)) { duration = TopTenScores[1000]; } else if ((duration >= 2000) && (duration <= 2999)) { duration = TopTenScores[2000]; } else if ((duration >= 3000) && (duration <= 3999)) { duration = TopTenScores[3000]; } else if ((duration >= 4000) && (duration <= 4999)) { duration = TopTenScores[4000]; } else if ((duration >= 5000) && (duration <= 5999)) { duration = TopTenScores[5000]; } else if ((duration >= 6000) && (duration <= 6999)) { duration = TopTenScores[6000]; } else if ((duration >= 7000) && (duration <= 7999)) { duration = TopTenScores[7000]; } else if ((duration >= 8000) && (duration <= 8999)) { duration = TopTenScores[8000]; } else if ((duration >= 9000) && (duration <= 9999)) { duration = TopTenScores[9000]; } Console.WriteLine(TopTenScores); } static void Main(string[] args) { int intInput, num1, num2, incorrect, array1; float answer; string input; System.Random randNum = new System.Random(); Console.WriteLine("Welcome to the Maths game!"); Console.WriteLine("(Apologies for the glitchiness!)"); Console.WriteLine(); Console.WriteLine("Please choose from the following options:"); Console.WriteLine(); retry: Console.WriteLine("1 - Test your Maths against the clock!"); Console.WriteLine("2 - Exit the application."); Console.WriteLine("3 - Top scores"); Console.WriteLine(); input = Console.ReadLine(); intInput = int.Parse(input); if (intInput == 1) { goto start; } else if (intInput == 2) { goto fin; } else if (intInput == 3) { array1 = array1.saveInArray; goto retry; } Now, in the last 'else if' statement in the code, you can see my variable array1 trying to call the method, but no matter what I do I keep getting errors. This is the only error I have at the moment, but I have a feeling soon as I resolve that error, another will come up. For now i'm just determined to get past this error: 'int' does not contain a definition for 'saveInArray' and no extension method 'saveInArray' accepting a first argument of type 'int' could be found (are you missing a using directive or an assembly reference?). Any help would be kindly appreciated, apologies in advanced for my ugly written code! And thank you to any help that I receive! Regards, Omar.

  • How do you control what your C compiler Optimizes?

    - by Jordan S
    I am writing the firmware for an embedded device in C using the Silicon Labs IDE and the SDCC compiler. The device architecture is based on the 8051 family. The function in question is shown below. The function is used to set the ports on my MCU to drive a stepper motor. It gets called in by an interrupt handler. The big switch statement just sets the ports to the proper value for the next motor step. The bottom part of the function looks at an input from a hall effect sensor and a number of steps moved in order to detect if the motor has stalled. The problem is, for some reason the second IF statement that looks like this if (StallDetector > (GapSize + 20)) { HandleStallEvent(); } always seems to get optimized out. If I try to put a breakpoint at the HandleStallEvent() call the IDE gives me a message saying "No Address Correlation to this line number". I am not really good enough at reading assembly to tell what it is doing but I have pasted a snippet from the asm output below. Any help would be much appreciated. void OperateStepper(void) { //static bit LastHomeMagState = HomeSensor; static bit LastPosMagState = PosSensor; if(PulseMotor) { if(MoveDirection == 1) // Go clockwise { switch(STEPPER_POSITION) { case 'A': STEPPER_POSITION = 'B'; P1 = 0xFD; break; case 'B': STEPPER_POSITION = 'C'; P1 = 0xFF; break; case 'C': STEPPER_POSITION = 'D'; P1 = 0xFE; break; case 'D': STEPPER_POSITION = 'A'; P1 = 0xFC; break; default: STEPPER_POSITION = 'A'; P1 = 0xFC; } //end switch } else // Go CounterClockwise { switch(STEPPER_POSITION) { case 'A': STEPPER_POSITION = 'D'; P1 = 0xFE; break; case 'B': STEPPER_POSITION = 'A'; P1 = 0xFC; break; case 'C': STEPPER_POSITION = 'B'; P1 = 0xFD; break; case 'D': STEPPER_POSITION = 'C'; P1 = 0xFF; break; default: STEPPER_POSITION = 'A'; P1 = 0xFE; } //end switch } //end else MotorSteps++; StallDetector++; if(PosSensor != LastPosMagState) { StallDetector = 0; LastPosMagState = PosSensor; } else { if (PosSensor == ON) { if (StallDetector > (MagnetSize + 20)) { HandleStallEvent(); } } else if (PosSensor == OFF) { if (StallDetector > (GapSize + 20)) { HandleStallEvent(); } } } } //end if PulseMotor } ... and the asm output for the the bottom part of this function... ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:653: if(PosSensor != LastPosMagState) mov c,_P1_4 jb _OperateStepper_LastPosMagState_1_1,00158$ cpl c 00158$: jc 00126$ C$MotionControl.c$655$3$7 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:655: StallDetector = 0; clr a mov _StallDetector,a mov (_StallDetector + 1),a C$MotionControl.c$657$3$7 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:657: LastPosMagState = PosSensor; mov c,_P1_4 mov _OperateStepper_LastPosMagState_1_1,c ret 00126$: C$MotionControl.c$661$2$8 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:661: if (PosSensor == ON) jb _P1_4,00123$ C$MotionControl.c$663$4$9 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:663: if (StallDetector > (MagnetSize + 20)) mov a,_MagnetSize mov r2,a rlc a subb a,acc mov r3,a mov a,#0x14 add a,r2 mov r2,a clr a addc a,r3 mov r3,a clr c mov a,r2 subb a,_StallDetector mov a,r3 subb a,(_StallDetector + 1) jnc 00130$ C$MotionControl.c$665$5$10 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:665: HandleStallEvent(); ljmp _HandleStallEvent 00123$: C$MotionControl.c$668$2$8 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:668: else if (PosSensor == OFF) jnb _P1_4,00130$ C$MotionControl.c$670$4$11 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:670: if (StallDetector > (GapSize + 20)) mov a,#0x14 add a,_GapSize mov r2,a clr a addc a,(_GapSize + 1) mov r3,a clr c mov a,r2 subb a,_StallDetector mov a,r3 subb a,(_StallDetector + 1) jnc 00130$ C$MotionControl.c$672$5$12 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:672: HandleStallEvent(); C$MotionControl.c$678$2$1 ==.

  • C# 'is' type check on struct - odd .NET 4.0 x86 optimization behavior

    - by Jacob Stanley
    Since upgrading to VS2010 I'm getting some very strange behavior with the 'is' keyword. The program below (test.cs) outputs True when compiled in debug mode (for x86) and False when compiled with optimizations on (for x86). Compiling all combinations in x64 or AnyCPU gives the expected result, True. All combinations of compiling under .NET 3.5 give the expected result, True.

  • Trying to reduce the speed overhead of an almost-but-not-quite-int number class

    - by Fumiyo Eda
    I have implemented a C++ class which behaves very similarly to the standard int type. The difference is that it has an additional concept of "epsilon" which represents some tiny value that is much less than 1, but greater than 0. One way to think of it is as a very wide fixed point number with 32 MSBs (the integer parts), 32 LSBs (the epsilon parts) and a huge sea of zeros in between. The following class works, but introduces a ~2x speed penalty in the overall program. (The program includes code that has nothing to do with this class, so the actual speed penalty of this class is probably much greater than 2x.) I can't paste the code that is using this class, but I can say the following: +, -, +=, <, > and >= are the only heavily used operators. Use of setEpsilon() and getInt() is extremely rare. * is also rare, and does not even need to consider the epsilon values at all. Here is the class: #include <limits> struct int32Uepsilon { typedef int32Uepsilon Self; int32Uepsilon () { _value = 0; _eps = 0; } int32Uepsilon (const int &i) { _value = i; _eps = 0; } void setEpsilon() { _eps = 1; } Self operator+(const Self &rhs) const { Self result = *this; result._value += rhs._value; result._eps += rhs._eps; return result; } Self operator-(const Self &rhs) const { Self result = *this; result._value -= rhs._value; result._eps -= rhs._eps; return result; } Self operator-( ) const { Self result = *this; result._value = -result._value; result._eps = -result._eps; return result; } Self operator*(const Self &rhs) const { return this->getInt() * rhs.getInt(); } // XXX: discards epsilon bool operator<(const Self &rhs) const { return (_value < rhs._value) || (_value == rhs._value && _eps < rhs._eps); } bool operator>(const Self &rhs) const { return (_value > rhs._value) || (_value == rhs._value && _eps > rhs._eps); } bool operator>=(const Self &rhs) const { return (_value >= rhs._value) || (_value == rhs._value && _eps >= rhs._eps); } Self &operator+=(const Self &rhs) { this->_value += rhs._value; this->_eps += rhs._eps; return *this; } Self &operator-=(const Self &rhs) { this->_value -= rhs._value; this->_eps -= rhs._eps; return *this; } int getInt() const { return(_value); } private: int _value; int _eps; }; namespace std { template<> struct numeric_limits<int32Uepsilon> { static const bool is_signed = true; static int max() { return 2147483647; } } }; The code above works, but it is quite slow. Does anyone have any ideas on how to improve performance? There are a few hints/details I can give that might be helpful: 32 bits are definitely insufficient to hold both _value and _eps. In practice, up to 24 ~ 28 bits of _value are used and up to 20 bits of _eps are used. I could not measure a significant performance difference between using int32_t and int64_t, so memory overhead itself is probably not the problem here. Saturating addition/subtraction on _eps would be cool, but isn't really necessary. Note that the signs of _value and _eps are not necessarily the same! This broke my first attempt at speeding this class up. Inline assembly is no problem, so long as it works with GCC on a Core i7 system running Linux!

  • Ado.Net Entity produces "namespace cannot be found"

    - by Dave
    I've seen several possible solutions to this, but none have worked for me. After adding a ADO.NET Entity Data Model to my .Net Forms C# web project, I am unable to use it. Perhaps I made a mistake adding it? The name of the file added is QcFormData.edmx. In my code, perhaps I'm instantiating it incorrectly? I tried adding the line: QcFormDataContainer db = new QcFormDataContainer(); It appears in Intellisense, but when compiling I get the error : Error 13 The type or namespace name 'QcFormDataContainer' could not be found (are you missing a using directive or an assembly reference?) I've followed the suggestions that I found online that did not help: 1) made sure there is "using System.Data.Entity" 2) made sure the dll exists. 3) made sure the reference exists. 4) one post said use using System.Web.Data.Entity; but I do not see that available.

  • MEF + Plug-In not updating

    - by mybrokengnome
    I asked this on the MEF Codeplex forum already, but I haven't gotten a response yet, so I figured I'd try StackOverflow. Here's the original post if anyone's interested (this is just a copy from it): MEF Codeplex "Let me first say that I'm completely new to MEF (just discovered it today) and am very happy with it so far. However, I've ran in to a problem that is very frustrating. I'm creating an app that will have a plugin architecture and the plugins will only be stored in a single DLL file (or coded into the main app). The DLL file needs to be able to be recompiled during run-time and the app should recognize this and re-load the plugins (I know this is difficult, but it's a requirement). To accomplish this I took the approach covered http://blog.maartenballiauw.be/category/MEF.aspx there (look for WebServerDirectoryCatalog). Basically the idea is to "monitor the plugins folder, copy the new/modified assemblies to the web application’s /bin folder and instruct MEF to load its exports from there." This is my code, which is probably not the correct way to do it but it's what I found in some samples around the net: main()... string myExecName = Assembly.GetExecutingAssembly().Location; string myPath = System.IO.Path.GetDirectoryName(myExecName); catalog = new AggregateCatalog(); pluginCatalog = new MyDirectoryCatalog(myPath + @"/Plugins"); catalog.Catalogs.Add(pluginCatalog); exportContainer = new CompositionContainer(catalog); CompositionBatch compBatch = new CompositionBatch(); compBatch.AddPart(this); compBatch.AddPart(catalog); exportContainer.Compose(compBatch); and private FileSystemWatcher fileSystemWatcher; public DirectoryCatalog directoryCatalog; private string path; private string extension; public MyDirectoryCatalog(string path) { Initialize(path, "*.dll", "*.dll"); } private void Initialize(string path, string extension, string modulePattern) { this.path = path; this.extension = extension; fileSystemWatcher = new FileSystemWatcher(path, modulePattern); fileSystemWatcher.Changed += new FileSystemEventHandler(fileSystemWatcher_Changed); fileSystemWatcher.Created += new FileSystemEventHandler(fileSystemWatcher_Created); fileSystemWatcher.Deleted += new FileSystemEventHandler(fileSystemWatcher_Deleted); fileSystemWatcher.Renamed += new RenamedEventHandler(fileSystemWatcher_Renamed); fileSystemWatcher.IncludeSubdirectories = false; fileSystemWatcher.EnableRaisingEvents = true; Refresh(); } void fileSystemWatcher_Renamed(object sender, RenamedEventArgs e) { RemoveFromBin(e.OldName); Refresh(); } void fileSystemWatcher_Deleted(object sender, FileSystemEventArgs e) { RemoveFromBin(e.Name); Refresh(); } void fileSystemWatcher_Created(object sender, FileSystemEventArgs e) { Refresh(); } void fileSystemWatcher_Changed(object sender, FileSystemEventArgs e) { Refresh(); } private void Refresh() { // Determine /bin path string binPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Plugins"); string newPath = ""; // Copy files to /bin foreach (string file in Directory.GetFiles(path, extension, SearchOption.TopDirectoryOnly)) { try { DirectoryInfo dInfo = new DirectoryInfo(binPath); DirectoryInfo[] dirs = dInfo.GetDirectories(); int count = dirs.Count() + 1; newPath = binPath + "/" + count; DirectoryInfo dInfo2 = new DirectoryInfo(newPath); if (!dInfo2.Exists) dInfo2.Create(); File.Copy(file, System.IO.Path.Combine(newPath, System.IO.Path.GetFileName(file)), true); } catch { // Not that big deal... Blog readers will probably kill me for this bit of code :-) } } // Create new directory catalog directoryCatalog = new DirectoryCatalog(newPath, extension); directoryCatalog.Refresh(); } public override IQueryable<ComposablePartDefinition> Parts { get { return directoryCatalog.Parts; } } private void RemoveFromBin(string name) { string binPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, ""); File.Delete(Path.Combine(binPath, name)); } So all this actually works, and after the end of the code in main my IEnumerable variable is actually filled with all the plugins in the DLL (which if you follow the code is located in Plugins/1 so that I can modify the dll in the plugins folder). So now at this point I should be able to re-compile the plugins DLL, drop it in to the Plugins folder, my FileWatcher detect that it's changed, and then copy it into folder "2" and directoryCatalog should point to the new folder. All this actually works! The problem is, even though it seems like every thing is pointed to the right place, my IEnumerable variable is never updated with the new plugins. So close, but yet so far! Any suggestions? I know the downsides of doing it this way, that no dll is actually getting unloaded and causing a memory leak, but it's a Windows App and will probably be started at least once a day, and the plugins are un-likely to change that often, but it's still a requirement from the client that it does this without re-loading the app. Thanks! Thanks for any help you all can provide, it's driving me crazy not being able to figure this out."

  • How to retrieve ID of button clicked within usercontrol on Asp.net page?

    - by Shawn Gilligan
    I have a page that I am working on that I'm linking multiple user controls to. The user control contains 3 buttons, an attach, clear and view button. When a user clicks on any control on the page, the resulting information is "dumped" into the last visible control on the page. <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default" MasterPageFile="DefaultPage.master" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %> <%@ Register tagName="FileHandler" src="FileHandling.ascx" tagPrefix="ucFile" %> <asp:Content ID="Content1" ContentPlaceHolderID="Main" Runat="Server"> <asp:UpdatePanel ID="upPanel" UpdateMode="Conditional" runat="server"> <ContentTemplate> <table> <tr> <td> <ucFile:FileHandler ID="fFile1" runat="server" /> </td> <td> <ucFile:FileHandler ID="fFile2" runat="server" /> </td> </tr> </table> </ContentTemplate> </asp:UpdatePanel> </asp:Content> All file handling and processing is handled within the control, with an event when the upload to the file server is complete via a file name that was generated. When either button is clicked, the file name is always stored internal to the control in the last control's text box.

  • Mass targeted malware installed - g00glestatic.com [closed]

    - by Silver89
    Possible Duplicate: My server’s been hacked EMERGENCY I run a webserver which over the last few days seems to have become infected with malware that tries to include content from "http://g00glestatic.com/s.js" It appears the attacker gained access to one of the user accounts (not root), made a few changes, added a few files and ran a few bash commands. These changes stuck out clearly to me because it is not a shared server and I am the only person with access through very secure passwords.

What else do I need to look for to check the malware infection has not spread? Second Conclusion This malware sinks too deep to 'clean', if you get infected I recommend a server nuke and rebuild from backups with increased security. Possibility It's possible that Filezilla ftp passwords were stolen through a trojan as they're unfortunately stored unencrypted. However Trend Micro Titanium has not found any. The settings box to disable passwords being saved has now been ticked, I also recommend that you take this action.

  • Subscript out of range error in VBScript script

    - by SteveW
    I'm trying to move my entire User folder in Windows Vista to a non-system partition. To do so with a minimum hassle I'm following the directions provided at Ben's Blog, specifically the VBScript he provides. However executing the script throws up an error which I can't resolve myself. Here's the VBScript code followed by the text file it works from, and finally my error message. How do I correct the problem? VBScript Code: '# Perform dir /a c:\users > c:\dir.txt '# place this script file in c:\ too '# double click to run it '# run resulting script.bat from recovery mode repprefix = " Directory of..."

  • How does one get rid of fishy behavior in Windows?

    - by Tom Wijsman
    After I had boot my computer this morning there suddenly flooded water from the top of the screen, after which some fishes dropped into it. Now I can barely see what I am doing because the water distorts the view. Sometimes the fish follow the cursor so I need to move it away or wait for the fish to mind their own business. This makes it very annoying to use my system. What have I tried? Reboot the system. This caused the water to deplete from the desktop. Upon reboot, the screen was refilled with water and fishes. Attach another monitor. Same problem, fills that monitor as well and gives me extra fish. Clicking the fish. Makes them turn direction. Right clicking the fish. Changes color of the fish, not really useful. I'm locked out of changing the background or screen saver settings. Hence, I had to post the lady below... Safe mode doesn't save me from the fishes. It does give me another background there, but I can't screenshot easily. Other user accounts experience this as well. The Guest account seems to experience more fish than the other accounts. Using HijackThis, OTL Timekeeper List, Syninternal Autoruns, RootKitRevealer, ShellExView and similar tools I can't seem to find any entries that could be it, the Sysinternals tools show everything as verified. I'm suspecting this to be a driver problem. Randomly removing drivers doesn't seem to alleviate the problem. When removing the Graphics Drivers, it makes my screen black. While that could be considered the solution, it's not what I want. Changing the time / date settings does also not seem to affect the fishes. Changing the time a few years in the future, I would have expected the fishes to be dead. But, the same fishes are still there... They simply won't die! Tried to get used to them. They are really bothering me, looks like they require food. I don't know how to give them food, but apparently they get it elsewhere during reboot... Tried to disable my mouse pointer and use the keyboard. This works, they now swim around more randomly. They do put their attention to huge changes on the screen, so I need to type slow. Or otherwise I can't see what I'm tying exactly. Hold my laptop upside down. This seems to affect the water and fishes, but the water stays in the screen. They seem super resistant against water sickness and confusion though... What does the problem look like? What do I need? A way to get rid of these fishes on my screen forever, they are really annoying me a lot and I'm about to crack the screen to see if that makes them escape. Do you have any idea why this problem is occurring? What are my considerations? Buying an USB fish tank could make the fish leave the screen, I am uncertain though whether the fish could leave the screen through the USB cable. Using the FISh (programming language) which seems to provide EXPRESSIVE POWER and EFFICIENT EXECUTION, I can however not find any examples on how to remove fish. What are my Specifications? I'm using a Sony Vaio Fishy laptop. Sony VAIO VGN-Fishy, VAIO. Processor: 1337 MHz, Intel Core 2 Duo, T5432, 1 MB, Intel PM965 Express, 667 MHz.

  • MySQL 5.1.49 freezing every two days

    - by maximus
    Hi all, our mysql system is "freezing" every two days. By "freezing" i mean the following: it doesn't respond to ping we can't login with SSH we don't get any answer from MySQL there is no entry in the error logs! neither from linux neither from MySQL. we have already changed to a completely new hardware, we have the same problem, so it's definitely not a hardware problem. we do not have any other software installed except a firewall (iptables rule) we can restart the server from another server using rsyslog (www.rsyslog.com)(software reset) Could someone help me, by giving me some pointers what could i do to figure out the problem? I have included every detail about our settings. Thank you in advance for your help. Max.

  • Allowing connections initiated from outside

    - by Mark S. Rasmussen
    I've got an old Juniper SSG5 running ScreenOS 5.4.0r6.0. Once a day, more or less, it'll start randomly dropping packets at a rate of ~5-10%. We currently solve this issue by simply rebooting the unit, after which it resumes working in perfect condition. As this error has started appearing randomly, without any configuration or hardware changes, I'm assuming I've got an aging unit about to fail. As such, I've got a replacement SSG5 running ScreenOS 6.0. I've dumped the config on the 5.4 and imported it into a clean 6.0, and it seems to gladly accept it, and all my configuration seems to be A-OK. However, upon connecting the new unit, all outside-initiated connections seem to be blocked. If I browse our external IP from the inside, everything works perfectly, and it's not just port 80, SSH, Crashplan - all of our policies route correctly. All normal networking, initiated from the inside, work perfectly as well. If on the other hand I browse our external IP from the outside, everything is blocked. Barring differences between ScreenOS 5.4 and 6.0, the config is identical. Is there a setting somewhere that defines whether outside/inside initiated connections are allowed? unset key protection enable set clock timezone 1 set vrouter trust-vr sharable set vrouter

  • Print driver installs failing

    - by Kasius
    All of the Windows 7 64-bit Enterprise machines in my organization are failing to install a good number of printer drivers that previously installed without issue. This only happens with printer drivers. And not with all printer drivers. Just some. Network drivers, video drivers, etc. have had no problems. Here is part of setupapi.dev.log for a Dymo LabelWriter printer driver that is failing to install: dvi: {Plug and Play Service: Device Install for USBPRINT\DYMOLABELWRITER_450_TURBO\6&538F51D&0&USB001} ump: Creating Install Process: DrvInst.exe 09:36:58.071 ndv: Infpath=C:\Windows\INF\oem0.inf ndv: DriverNodeName=dymo.inf:DYMO.NTamd64.6.0:LW_450_TURBO_VISTA:8.1.0.363:usbprint\dymolabelwriter_450_aa08 ndv: DriverStorepath=C:\Windows\System32\DriverStore\FileRepository\dymo.inf_amd64_neutral_3a631b118b7a5828\dymo.inf ndv: Building driver list from driver node strong name... dvi: Searching for hardware ID(s): dvi: usbprint\dymolabelwriter_450_aa08 dvi: dymolabelwriter_450_aa08 inf: Opened PNF: 'C:\Windows\System32\DriverStore\FileRepository\dymo.inf_amd64_neutral_3a631b118b7a5828\dymo.inf' ([strings]) dvi: Selected driver installs from section [LW_450_TURBO_VISTA] in 'c:\windows\system32\driverstore\filerepository\dymo.inf_amd64_neutral_3a631b118b7a5828\dymo.inf'. dvi: Class GUID of device changed to: {4d36e979-e325-11ce-bfc1-08002be10318}. dvi: Set selected driver complete. ndv: {Core Device Install} 09:36:58.133 inf: Opened INF: 'C:\Windows\INF\oem0.inf' ([strings]) inf: Saved PNF: 'C:\Windows\INF\oem0.PNF' (Language = 0409) dvi: {DIF_ALLOW_INSTALL} 09:36:58.164 dvi: Using exported function 'ClassInstall32' in module 'C:\Windows\system32\ntprint.dll'. dvi: Class installer == ntprint.dll,ClassInstall32 dvi: No CoInstallers found dvi: Class installer: Enter 09:36:58.164 dvi: Class installer: Exit dvi: Default installer: Enter 09:36:58.180 dvi: Default installer: Exit dvi: {DIF_ALLOW_INSTALL - exit(0xe000020e)} 09:36:58.180 ndv: Installing files... dvi: {DIF_INSTALLDEVICEFILES} 09:36:58.180 dvi: Class installer: Enter 09:36:58.180 inf: Opened INF: 'C:\Windows\System32\DriverStore\FileRepository\dymo.inf_amd64_neutral_3a631b118b7a5828\dymo.inf' ([strings]) inf: Opened INF: 'C:\Windows\System32\DriverStore\FileRepository\dymo.inf_amd64_neutral_3a631b118b7a5828\dymo.inf' ([strings]) !!! dvi: Class installer: failed(0x00000490)! !!! dvi: Error 1168: Element not found. dvi: {DIF_INSTALLDEVICEFILES - exit(0x00000490)} 09:37:22.063 ndv: Device install status=0x00000490 ndv: Performing device install final cleanup... ! ndv: Queueing up error report since device installation failed... ndv: {Core Device Install - exit(0x00000490)} 09:37:22.063 dvi: {DIF_DESTROYPRIVATEDATA} 09:37:22.063 dvi: Class installer: Enter 09:37:22.063 dvi: Class installer: Exit dvi: Default installer: Enter 09:37:22.063 dvi: Default installer: Exit dvi: {DIF_DESTROYPRIVATEDATA - exit(0xe000020e)} 09:37:22.063 ump: Server install process exited with code 0x00000490 09:37:22.063 ump: {Plug and Play Service: Device Install exit(00000490)} Notice these lines in particular: !!! dvi: Class installer: failed(0x00000490)! !!! dvi: Error 1168: Element not found. dvi: {DIF_INSTALLDEVICEFILES - exit(0x00000490)} 09:37:22.063 ndv: Device install status=0x00000490 From what I have read, the "Element not found" error should be accompanied by an event describing what element was not found. The error that appears in Device Manager is "The driver cannot be installed because it is either not digitally signed or not signed in the appropriate manner." It appears to be signed fine though. It has an accompanying .CAT file and worked previously. And when installing, the following messages are logged in setupapi.dev.log: sto: {DRIVERSTORE_IMPORT_NOTIFY_VALIDATE} 09:36:56.277 inf: Opened INF: 'C:\Windows\System32\DriverStore\Temp\{272e2305-961c-7942-9ede-966f01047043}\dymo.inf' ([strings]) sig: {_VERIFY_FILE_SIGNATURE} 09:36:56.292 sig: Key = dymo.inf sig: FilePath = C:\Windows\System32\DriverStore\Temp\{272e2305-961c-7942-9ede-966f01047043}\dymo.inf sig: Catalog = C:\Windows\System32\DriverStore\Temp\{272e2305-961c-7942-9ede-966f01047043}\DYMO.CAT sig: Success: File is signed in catalog. sig: {_VERIFY_FILE_SIGNATURE exit(0x00000000)} 09:36:56.355 sto: Validating driver package files against catalog 'DYMO.CAT'. sto: Driver package is valid. sto: {DRIVERSTORE_IMPORT_NOTIFY_VALIDATE exit(0x00000000)} 09:36:56.402 sto: Verified driver package signature: sto: Digital Signer Score = 0x0D000005 sto: Digital Signer Name = Microsoft Windows Hardware Compatibility Publisher Now here's where it gets strange. If I take it off the domain, it installs fine. But it doesn't seem to have anything to do with Group Policy. I moved the machine to an OU that blocks inheritance, ran a gpupdate, ran rsop.msc to verify, and tried again. And it still didn't work. Likewise, I removed a machine from the domain, manually set all of the domain Group Policy settings in gpedit.msc, and tried that way, and it worked fine. So it seems like the Group Policy settings are irrelevant. What other domain-related issue could be causing this though? Any ideas on what to try next would be greatly appreciated. I'm not sure where to go from here. Thanks!
