    - finding resourse leaks My application appears to have a recourse leak. When the user starts a background process, the handle count in Process Explorer (PE) goes up by about 10, sometime 1 or 2 more, sometimes 1 or 2 less. When the task is completed, there are somewhere between 4 and 7 handles still open. I am using an AutoResetEvent, but calling Close on it seems to have no effect. I know in the unmanaged code I have to close thread handles once I am finished with them, do I need to do something like that with threads in the managed world? I have gone through the code and it looks like I have all the lose ends tied up now, are there any not so obvious objects which need to be disposed? My process is loading images and shrinking them down. I have checked the file objects, image objects, graphics objects and everything is being disposed of once it is no longer needed.

    - Compiling multiple win32 resources into an assembly Hi, I have a build process in which my .NET projects get compiled using a common version resource which is compiled into a .RES file. My project files import a shared MSBuild file which uses the Win32Resource tag. eg: (abbreviated for readability) MyCommon.targets: ---------------- <PropertyGroup> <Win32Resource>version.res</Win32Resource> </PropertyGroup> MyExe.csproj ------------ <PropertyGroup> <ApplicationIcon>app.ico</ApplicationIcon> </PropertyGroup> <Import Project="MyCommon.targets" /> The problem is that when I try to build MyExe.csproj I get the following error: CSC : error CS1565: Conflicting options specified: Win32 resource file; Win32 icon because apparently Win32Resource and ApplicationIcon tags are mutually exclusive. To get around this, I compiled the application icon into a new .RES file and added it to the project using the Win32Resource tag. eg: MyExe.csproj ------------ <PropertyGroup> <Win32Resource>app.res</Win32Resource> </PropertyGroup> <Import Project="MyCommon.targets" /> The build error goes away, the file is versioned correctly, but there's no application icon -- the EXE has the generic icon. It looks like the resource in MyCommon.targets overrides the one defined in my executable project. If I remove the Win32Resource tag in MyCommon.targets, then my EXE has the right icon, but then it doesn't get versioned. So my question is, how can I specify multiple Win32Resource tags? I'd like to do something like <PropertyGroup> <Win32Resource>$(Win32Resource);version.res</Win32Resource> </PropertyGroup> ...in MyCommon.targets to append to a list. BTW, I've tried that syntax and it doesn't work. I get the following error: CSC : fatal error CS2021: File name 'app.res;..\version.res' is too long or invalid Thanks, CM Tag: NET Regular Exp patterns work in VB6? Tag: 138152

    - Resource leak (handles count) in simple .NET application Hi I have a resource leak in the very simple project. Project contains Form with one TextBox control in multiline mode. After start this app I open Task Manager and see "Handles" count incremental on every 1 second. The source code is following: public partial class Form1 : Form { System.Threading.Timer tm; public Form1() { InitializeComponent(); // start timer 1 second interval ... tm = new System.Threading.Timer(OnTimer, null, 0, 1000); } void OnTimer(Object state) { // add text in thread safe mode ... AddTerminalText(" Resource Leak!!! "); } delegate void AddTextCallback(string text); AddTextCallback d; object[] arg = new object[1]; private void AddTerminalText(string text) { if (textBox1.InvokeRequired) { if (d == null) { d = new AddTextCallback(AddTerminalText); } arg[0] = text; textBox1.Invoke(d, arg); } else { textBox1.AppendText(text); // add text into control ... } } } I don't understand what's wrong Please help anybody !!!

    - ClickOnce Deployment (BUG?) Hello guys, There is an application (c# @ vs2005 SP1) that needs to be deployed in a very controlled way. ClickOnce was selected to do this task. This application works over a database and, some times, this database needs to be updated together with the code. The problem is that not all the clients are in the same local network, so, secondary servers were deployed using windows services to transfer the information and to update and sign manifests, and then clients subscribe to the local secondary server for updates. Not all the clients have this advantage, several need to connect directly to the primary server, so the updating process is slow and for this ClickOnce has a great feature of download updates on the background. This is done creating Download Groups and it works well. The problem is that, when I download some files, I want to leave a small group at the server for update at the moment the administrator decide. That works ok, but when the app is closed and opened again, the application asks the user if he/she wants to update the application because a new download is available. I'm sure that I unchecked the "The application should check for updates" checkbox of the application updates dialog of the publish settings on the project properties. Is there any way to stop the window's display? I think it's a bug! Any ideas? Thanks in advance. FM. Tag: NET Regular Exp patterns work in VB6? Tag: 138138

    - Framework Registers/Stack restoration on exceptions What does the framework for stack/registers restoration when an exception is thrown ? Is there any way to act on the stack before/after framework does it's stack restoration ? I currently know that .NET use the default exception handler with an array of callback for catch blocks (at least 1.0 and 1.1), but if we play with stack before an exception is thrown, Framework fails to restore stack gracefully...

    - .NET debugging environment crash I am writing an app using C# for v2.0 of the framework. As I am still in development, debug mode has been very helpful; however, I am experiencing an IndexOutOfRange error that the environment is unable to catch. When it occurs, the "debug" dialog pops up but clicking the button and then selecting "Visual Studio 2005" fails to run VS properly. Instead, both processes (my app and VS) crash with a message like "... failed to attach to crashing process". This is disconcerting as any and all other exceptions are properly caught and, with the help of PDB files, located in the source code. I do not use any outside DLLs. I compile all code in debug mode myself. Any pointers as to what may be preventing the debugging environment from handling this error? Tag: NET Regular Exp patterns work in VB6? Tag: 138122

Now, I add a button in the main form, I want that if the user click the button. It will show the about form . In button's event . the code like this: { about.show(); } but it doesn't work, if in Delphi. It will be work. After that, I search the msdn.

    - WorkflowCompiler Error I am using the WorkflowCompiler to compile xoml workflows at runtime into DLL files. This has been working great, but lately after upgrading to .NET 3.5 (it seems - possibly this is unrelated) sporradically I get the following error: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at System.Workflow.ComponentModel.Compiler.WorkflowCompilerInternal.Compile(WorkflowCompilerParameters parameters, String[] allFiles) at System.Workflow.ComponentModel.Compiler.WorkflowCompiler.Compile(WorkflowCompilerParameters parameters, String[] files) at MaryKay.CRM.BusinessLayer.WorkflowUtil.CompileWorkflowXoml(String xoml) in C:\Projects\FrontOffice\SAM-CRM\Current\Service Interface\MaryKay.CRM.Services\WorkflowUtil.cs:line 127 This is inconsistent and nearly impossible to debug (since it appears to happen inside the .NET Framework). We've rebooted the server, done other things and nothing seems to consistently resolve the issue - it just comes and goes. If I don't hear back from anyone on the newsgroups, I'll open an incident with Microsoft. Thanks in advance for your help. Tag: NET Regular Exp patterns work in VB6? Tag: 138097

    - multithreading with WPF I'm trying to understand how to speed up the ui. I have been experimenting with background processing, but am not getting results that I think I should. To experiment, I've created a window that contains a bunch of randomly sized and placed circles. My goal is to be able to resize the window without it hanging or being sluggish. To reduce the processing in the main thread, I've created a BackgroundWorker thread to handle as much processing as I can. Given the design, I believe that the windows sizing shouldn't be affected by the value of numberOfPoints. I expect the update to be delayed, but the resizing to be independent; however, that is not what I am getting. Does anyone have any suggestions? Also, I found that I was not able to freeze a VisualBrush after setting the visual. Any suggestions on that? Here's my sample code: using System; using System.ComponentModel; using System.Windows; using System.Windows.Controls; using System.Windows.Media; using System.Windows.Shapes; namespace FreezeTesting { class FreezeTesting { } class DrawingPanel : Canvas { class WorkData { public Size Size { get; private set; } public WorkData(Size s) { Size = s; } } static Random r = new Random(); const int numberOfPoints = 1000; bool vis = false; BackgroundWorker bgworker = new BackgroundWorker(); public DrawingPanel() { Background = Brushes.White; bgworker.WorkerSupportsCancellation = true; bgworker.WorkerReportsProgress = true; bgworker.DoWork += new DoWorkEventHandler(bgworker_DoWork); bgworker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bgworker_RunWorkerCompleted); } void bgworker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { if (e.Cancelled == false) { VisualBrush vb = e.Result as VisualBrush; if (vb != null) { Background = vb; } DrawingBrush db = e.Result as DrawingBrush; if (db != null) { Background = db; } } } void bgworker_DoWork(object sender, DoWorkEventArgs e) { e.Result = null; WorkData wd = e.Argument as WorkData; if (wd != null) { if (vis) { DrawingVisual dv = new DrawingVisual(); using (DrawingContext dc = dv.RenderOpen()) { for (int i = 0; i < numberOfPoints; i++) { int rad = r.Next(10) + 10; dc.DrawEllipse(Brushes.Black, null, new Point(r.NextDouble() * wd.Size.Width, r.NextDouble() * wd.Size.Height), rad, rad); if (e.Cancel == true) return; } } VisualBrush vb = new VisualBrush(dv); vb.Freeze(); // throws an error... don't understand why e.Result = vb; } else { GeometryGroup gg = new GeometryGroup(); for (int i = 0; i < numberOfPoints; i++) { int rad = r.Next(10) + 10; gg.Children.Add(new EllipseGeometry(new Point(r.NextDouble() * wd.Size.Width, r.NextDouble() * wd.Size.Height), rad, rad)); if (e.Cancel == true) return; } GeometryDrawing gd = new GeometryDrawing(null, new Pen(Brushes.Black, 1), gg); DrawingBrush db = new DrawingBrush(); db.Drawing = gd; db.Freeze(); e.Result = db; } } } protected override void OnRenderSizeChanged(SizeChangedInfo sizeInfo) { base.OnRenderSizeChanged(sizeInfo); if (bgworker.IsBusy) bgworker.CancelAsync(); bgworker.RunWorkerAsync(new WorkData(sizeInfo.NewSize)); } } class Win : Window { public Win() { Content = new DrawingPanel(); } } class App : Application { [STAThread()] static void Main() { new App(); } App() { Run(new Win()); } } } Tag: NET Regular Exp patterns work in VB6?

    - Problem with SHA256Managed when running multi-threaded Hi, I am experiencing problems with the SHA256Managed class when multiple threads are simultaneously using it. I have reduced the problem to a small piece of code (see below). This creates two threads, each of which repeatedly attempts to hash a string and compare the result to a previous attempt. After a number of tries, the result coming back is different. Running a single thread or locking the hashAlgo object stops the problem. However, this shouldn't be necessary as the documentation states that this class is thread safe when using a static instance. --- Code example: using System; using System.Security.Cryptography; using System.Text; namespace HashTester { class Program { static void Main(string[] args) { for (int i = 0; i < 2; i++) { System.Threading.Thread ff = new System.Threading.Thread(new System.Threading.ParameterizedThreadStart(HashTestFn)); ff.Start("pa$$word"); } } private static void HashTestFn(object o) { HashTest test = new HashTest(o.ToString()); for (int i = 0; i < 10000; i++) { test.Test(); } } } class HashTest { private static HashAlgorithm hashAlgo = new System.Security.Cryptography.SHA256Managed(); private string input; private string output; public HashTest(string toHash) { input = toHash; byte[] hashBytes; hashBytes = hashAlgo.ComputeHash(Encoding.ASCII.GetBytes(input)); output = Convert.ToBase64String(hashBytes).ToUpper(); } public void Test() { byte[] hashBytes = hashAlgo.ComputeHash(Encoding.ASCII.GetBytes(input)); string newOut = Convert.ToBase64String(hashBytes).ToUpper(); if (newOut != output) { throw new Exception("Bad Hash!!!!"); } } } } Tag: NET Regular Exp patterns work in VB6?

    - How server app can publish multiple Interface as Remoting on separate How Marshal the each Interface on two separate tcp ports channel? this is very often request, we have application that run as service. and we need to control it from within the office on separate port than client connect to get service (for add security). for example: ============ I have server (run as windows services) app that have two kind of service: interface1: for outside users on 50032 port interface1: second on 50033 port only for internal use (for Control Mng on this service) the two Interface (interface1 & interface2) share same Class instance. So I register two channel of tcp (the second one: props("name") = "tcp2" to avoid error: "already exists"), But how I can Attach each Marshal to each Port? some one wrote that need make it on two DomainApp, but how do that with one Class instance?

    - lambda question Hi, I have a question related to lambda expresions and how to prevent exceptions in a FindAll(). The following code create a list of objects and search for an item the "old" way and the "new" way: Create the list. List<object> list2 = new List<object>() { 1, 2, null, 6 }; Search for item "6" the old way. List<object> temp4 = list2.FindAll(delegate(object obj) { if (null != obj) { return object.Equals(obj.ToString(), "6"); } else { return false; } }); Search for item "6" the new way. List<object> temp3 = list2.FindAll(obj => object.Equals(obj.ToString(), "6")); The first method goes just fine because i'm able to check for null items. The second method fails because of the null item. How do i check for null items in the second method ?? Thank you in advance. BR Peter Tag: NET Regular Exp patterns work in VB6? Tag: 138073

    - Read() on ResponseStream of a HttpWebRequest always returns zero Hi, I have to check if a url like http://my_server/abc.aspx?id=123 sends a valid file. The server always returns OK as status code, but sends emtpy files, if the id is not correct. It's not possible for me to change the server side. Content-Lenght is always zero, because files are in a streaming format (I think). I tried to read the first 10 bytes of the file to check if it contains some valid data, but Read(...) returns zero bytes even for the valid ids. If I try the same url in IE, I'm able to download the file. Any hint what I might be doing wrong? Or another way to check the files? regards, Achim Tag: NET Regular Exp patterns work in VB6?

    - LINQ question This is a multi-part message in MIME format. ------=_NextPart_000_00EE_01C884E8.00DD6E90 Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=original Content-Transfer-Encoding: 7bit I have a desktop aplication which use an embeded database engine (embeded in the application that is) to store its data. And I used LINQ 2 SQL as an ORMapper to synchronize the database with my object representation in memory. What I want to do is load most object at the start, do in memory work, and occasionaly load additional big data or save the changes. I have a problem with the DataContext.GetTable<T>() mehod. It seems everytime I do a foreach on its retur it will query the database, is that true? So in my particular case I'm better off working with an List<T> which I will initialize from the GetTable<T> result? Just in case I wrote such a list (Code attached) and I wonder if I did it the proper way, if anyone can take a look? Also I have a table like that Data -------- ID int summary nvarchar(256) content image which I loaded in [Table("Data")] class Data { [Column(...)] public int ID {get; set; } [Column(...)] public sring Sumary { get; set; } [Column(...)] public byte[] Content { get; set; } } Now Content is potentially big and I want to use lazy loading, i.e. I DON'T want to load the 'byte[] Content' with the rest of the data (I guess it's easy, just remove the ColumnAttribute), but I DO want to save the Content, if it's not null (i.e. if it has been explicitely loaded/set/modified) when SubmitChanges() is called on the Context. Any tip on how to do that? Moreover, if I only change the content (which will have no ColumnAttribute) how do I mark my entity as dirty in the context? (i.e. I would need an 'UpdateOnSubmit()' method in the table, but it doesn't exists..) ------=_NextPart_000_00EE_01C884E8.00DD6E90 Content-Type: text/plain; format=flowed; name="LinqList.cs"; reply-type=original Content-Transfer-Encoding: quoted-printable Content-Disposition: attachment; filename="LinqList.cs" =EF=BB=BFusing System; using System.Collections.Generic; using System.Data.Linq; using System.Linq; using System.Linq.Expressions; using System.Text; namespace Galador.Utils.SQL { /// <summary> /// This will hol an in memory representation of some LINQ data. /// All data will be loaded at creation time and furter work would /// be done in memory. /// </summary> /// <typeparam name=3D"T"></typeparam> public class LinqList<T> : IList<T> where T : class { List<T> data; public LinqList(DataContext ctxt) { if (ctxt =3D=3D null) throw new ArgumentNullException("ctxt"); data =3D new List<T>(ctxt.GetTable<T>()); } public LinqList(DataContext ctxt, Expression<Func<T, bool>> predicate) { if (ctxt =3D=3D null) throw new ArgumentNullException("ctxt"); data =3D new List<T>(ctxt.GetTable<T>().Where<T>(predicate)); } public LinqList(DataContext ctxt, Expression<Func<T, int, bool>> = predicate) { if (ctxt =3D=3D null) throw new ArgumentNullException("ctxt"); data =3D new List<T>(ctxt.GetTable<T>().Where<T>(predicate)); } public LinqList(DataContext ctxt, Func<T, bool> predicate) { if (ctxt =3D=3D null) throw new ArgumentNullException("ctxt"); data =3D new List<T>(ctxt.GetTable<T>().Where<T>(predicate)); } public LinqList(DataContext ctxt, Func<T, int, bool> predicate) { if (ctxt =3D=3D null) throw new ArgumentNullException("ctxt"); data =3D new List<T>(ctxt.GetTable<T>().Where<T>(predicate)); } public DataContext Context { get; private set; } #region IList<T> Members public int IndexOf(T item) { return data.IndexOf(item); } public void Insert(int index, T item) { if (item !=3D null) Context.GetTable<T>().InsertOnSubmit(item); data.Insert(index, item); } public void RemoveAt(int index) { T item =3D data[index]; if (item !=3D null) Context.GetTable<T>().DeleteOnSubmit(item); data.RemoveAt(index); ; } public T this[int index] { get { return data[index]; } set { RemoveAt(index); Insert(index, value); } } #endregion #region ICollection<T> Members public void Add(T item) { Insert(Count, item); } public void Clear() { Context.GetTable<T>().DeleteAllOnSubmit<T>(data); data.Clear(); } public bool Contains(T item) { return data.Contains(item); } public void CopyTo(T[] array, int arrayIndex) { data.CopyTo(array, arrayIndex); } public int Count { get { return data.Count; } } public bool IsReadOnly { get { return false; } } public bool Remove(T item) { int index =3D IndexOf(item); if (index < 0) return false; RemoveAt(index); return true; } #endregion #region IEnumerable<T> Members public IEnumerator<T> GetEnumerator() { return data.GetEnumerator(); } #endregion #region IEnumerable Members System.Collections.IEnumerator = System.Collections.IEnumerable.GetEnumerator() { return GetEnumerator(); = } #endregion } } ------=_NextPart_000_00EE_01C884E8.00DD6E90-- Tag: NET Regular Exp patterns work in VB6?

    - How to capture "printfs" from unmanaged C++ I posted this to the interop group. I'm reposting to troll for a few more ideas. In my managed C# app we capture trace statements and direct them to a log file using trace listeners. Part of the app uses unmanaged C++ dlls, and unfortunately, the C++ printfs don't get picked up and are simply printed to the console window. Is there any way I can capture the output of the printfs and then redirect them to the same file that the trace listener is writing to? I do have access to the unmanaged C++ code if the solution involves not using printfs. The important thing is that the C++ printfs and the C# trace messages end up in the same file. One solution from the interop group was to compile the C++ with /clr and then replace the printfs with Trace.WriteLine(). Any less invasive techniques. Maybe somehow redirecting the printfs to someplace that can be picked up by .Net. Thanks Mitch Tag: NET Regular Exp patterns work in VB6? Tag: 138023

    - () in attribute declaration I have seen attributes, specifically Serializable declared in 2 ways and was wondering if anyone had any insight on the differance if there is any. These 2 ways are [Serializable] and [Serializable()]. Does the addition of the parenthesis do anything? Is this calling a constructor? Both seem to have the same effect in the end, but it seems like they should do something differnt? Tag: NET Regular Exp patterns work in VB6? Tag: 138007

    - System.Timers.Timer and Close/Dispose The short form of this post is as follows. For an instance of System.Timers.Timer, after setting Enabled to False, is there a foolproof way to tell if an Elapsed event will or will not fire? The long form follows. I have a class, MyClass, that declares Private WithEvents MyTimer As System.Timers.Timer Sub New for MyClass initializes MyTimer to fire Elapsed events every second. I have an Elapsed event handler and some public methods. With SyncLock, I've made MyClass instances thread safe. Everything works fine. System.Timers.Timer has Close and Dispose methods, so I when I want to destroy an instance of MyClass, I should Close or Dispose MyTimer. I've coded MyClass.Close to look like this: MyTimer.Enabled = False ' some cleanup I need to do Sleep(100) ' let fire an enroute MyTimer.Elapsed MyTimer.Dispose() ' per IDisposable ' some more cleanup I need to do The reason for the Sleep is because of how Windows/.NET executes MyTimer.Elapsed events. The Timer.Stop documentation says: "The Elapsed event is raised on a ThreadPool thread, so the event-handling method might run on one thread at the same time that a call to the Stop method runs on another thread. This might result in the Elapsed event being raised after the Stop method is called." Stop and Enabled=False do the same thing. The Timer.Stop documentation goes on to give a somewhat elaborate mechanism to overcome contention and race conditions that might arise. My solution is Sleep(100). I don't like my use of Sleep. I don't like the elaborate mechanism in the documentation because it looks like it could fail if someone is messing with thread priorities (note that the mechanism uses Sleep(0)). So, the question is: For an instance of System.Timers.Timer, after setting Enabled to False, is there a foolproof way to tell if an Elapsed event will or will not fire?

    - Good C# profilers? Hi... I was just wondering what recommendations people had for C# code profilers? I'm trying to figure out where a lot of our app's time is going. I downloaded and am trying ProfileSharp Enterprise Edition, but I'm finding the interface awkward and the results suspect (profiling for cpu cycles, it says Thread.Sleep is the most expensive function). Has anyone had particularly good experience with a C# code profiler? Thanks Mark Tag: NET Regular Exp patterns work in VB6? Tag: 138003

    - EnterpriseLibrary.Logging Hi all, I have installed EnterpriseLibrary v3.1 (latest version) on my pc. When I create the app.config file using the "EnterpriseLibrary Configuration" utility, I get an error saying it can't detect the EL.Logging.dll file. I fixed the problem by setting the PublicKeyToken= "null" instead of its default PublicKeyToken="b03f5f7f11d50a3a". eg. configSections> <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" /> <section name="exceptionHandling" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Configuration.ExceptionHandlingSettings, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" /> </configSections> The thing is that I can't understnad why this error is occuring in the first place. This pc is newly set-up and it has never had any prior versions of EL installed on it. The "EnterpriseLibrary Configuration" utility comes with this v3.1 setup. Thanks for your reply. regards, Andrew Tag: NET Regular Exp patterns work in VB6? Tag: 137998

    - GDI and Rotating Text Hi, I want to use GDI to rotate some text at an angle and output the resultant image to the asp.net response stream. I can do that all fine, however what I'm struggling with is trimming the whitespace from the resultant image. What im doing is creating a blank canvas image (of arbitrarily large size) and doing a translate transform to the centre, then applying a rotate transform, then writing my text. What i want to do is trim all the whitespace from around the edges. Is there some way i can determine the width and height of the text ive written to the image (after the transform) ? I know i can manually get the text dimensions before the rotate, then use some trig to work out how high and wide it would be after rotating it but thats a bit of a pain if theres some function that will do it for me Thanks for any advice Andrew Tag: NET Regular Exp patterns work in VB6?

    - Windows service startUp error Hi all, My question consists of 2 parts: 1) I have installed my windows service [by right-click on Setup.exe in SolutionExplorer, then Install ... ] onto a folder on my desktop. When I click on the MyNewService.exe file, I got the following error message: " Cannot start service from the command line or a debugger. A Windows Service must first be installed (using installutil.exe) and then started with the ServerExplorer, Windows Services Administrative tool or the NET START command. " 2) Is the problem because I need to install using "installutil /i C:\MyNewService3.exe" ? I tried that and i got the error message: " Exception occurred while initializing the installation: System.IO.FileNotFoundException: File or assembly name Documents, or one of its dependencies, was not found. " Any advice on understanding what this message says ? Thanks. regards, Andrew Tag: NET Regular Exp patterns work in VB6? Tag: 137978

    - Caching of DateTime.Now? Hi... We have some elapsed time stopwatches using the QueryPerformanceCounter() win32 api, but since I was getting tired of doing the arithmatic all the time I added some DateTime.Now.ToString("HH:mm:ss.fff")'s to the log and I noticed an interesting quirk. There's often about a 5ms difference between the calculations of QueryPerformanceCounter() values and DateTime.Now and DateTime.Now is always the one behind. Is DateTime.Now cached for some period of time to avoid the expense of recalculation? Thanks Mark Tag: NET Regular Exp patterns work in VB6? Tag: 137977

    - File Copy exception Hi all, I have created a windows service (my first service). I am normally an ASP.NET developer... The service is simple. All it does is to watch a directory and copy any files that land in it to another folder (in this case, the parent folder). This works fine most of the time, but my first sample file crashed it. It seems to be down to a file type problem. My sample file was a .bat file. I have now put a try/catch around the file copy and come up with _COMPlusExceptionCode -532459699 At the moment, it only seems to crash with .bat files. I have done a successful copy of app.config, *.txt. Any ideas? My code... public MyService() { InitializeComponent(); } protected override void OnStart(string[] args) { // TODO: Add code here to start your service. FSWatcher.Path = ConfigurationManager.AppSettings["WatchPath"]; } protected override void OnStop() { // TODO: Add code here to perform any tear-down necessary to stop your service. } private void FSWatcher_Created(object sender, System.IO.FileSystemEventArgs e) { try { System.IO.File.Copy(e.FullPath, "C:\\temp\\" + e.Name); } catch (Exception ex) { } } -- Best regards, Dave Colliver. http://www.AshfieldFOCUS.com ~~ http://www.FOCUSPortals.com - Local franchises available Tag: NET Regular Exp patterns work in VB6?

Not without work.

You could use JScript regular expressions:
http://www.regular-expressions.info/vb.html

Otherwise, you would to wrap the Regex class from .NET in a COM object that
could be used from VB6.
