  • How can I use foreach and fork together to do something in parallel?

    - by kaushalmodi
    This question is not UVM specific but the example that I am working on is UVM related. I have an array of agents in my UVM environment and I would like to launch a sequence on all of them in parallel. If I do the below: foreach (env.agt[i]) begin seq.start(env.agt[i].sqr); end , the sequence seq first executes on env.agt[0].sqr. Once that gets over, it then executes on env.agt[1].sqr and so on. I want to implement a foreach-fork statement so that seq is executed in parallel on all agt[i] sequencers. No matter how I order the fork-join and foreach, I am not able to achieve that. Can you please help me get that parallel sequence launching behavior? Thanks.

  • Is there any way to identify a unique user in Flash/Actionscript 3?

    - by VGambit
    I'm trying to make a vote/poll application in Flash using Actionscript 3. Is there any way to generate a specific ID that is unique to each user? The only other option I can think of is using the IP address, which is less than ideal in many cases (college campuses, shared Internet access, etc.). It needs to be the same number every time it is run on the same PC, but different for each user.

  • How can I shrink my Windows partition further than the disk management is allowing?

    - by Walkerneo
    I just bought a new computer with a 2tb hard drive that has only a single partition. I would like to divide this into at least 4 partitions, but when I try to shrink the current partition, it says the total size is 1888171 MB and that the size of available shrink space is only 939075 MB. The used disk space is at 40gb right now - why can't shrink it to somewhere around that? I read here: http://www.howtogeek.com/howto/windows-vista/working-around-windows-vistas-shrink-volume-inadequacy-problems/ that this is because of unmovable system files. I doubt this is the only problem though. I would like to get this partition down to 500gb. How can I do this?

  • public class ImageHandler : IHttpHandler

    - by Ken
    cmd.Parameters.AddWithValue("@id", new system.Guid (imageid)); What using System reference would this require? Here is the handler: using System; using System.Collections.Specialized; using System.Web; using System.Web.Configuration; using System.Web.Security; using System.Globalization; using System.Configuration; using System.Data.SqlClient; using System.Data; using System.IO; using System.Web.Profile; using System.Drawing; public class ImageHandler : IHttpHandler { public void ProcessRequest(HttpContext context) { string imageid; if (context.Request.QueryString["id"] != null) imageid = (context.Request.QueryString["id"]); else throw new ArgumentException("No parameter specified"); context.Response.ContentType = "image/jpeg"; Stream strm = ShowProfileImage(imageid.ToString()); byte[] buffer = new byte[8192]; int byteSeq = strm.Read(buffer, 0, 8192); while (byteSeq > 0) { context.Response.OutputStream.Write(buffer, 0, byteSeq); byteSeq = strm.Read(buffer, 0, 8192); } //context.Response.BinaryWrite(buffer); } public Stream ShowProfileImage(String imageid) { string conn = ConfigurationManager.ConnectionStrings["MyConnectionString1"].ConnectionString; SqlConnection connection = new SqlConnection(conn); string sql = "SELECT image FROM Profile WHERE UserId = @id"; SqlCommand cmd = new SqlCommand(sql, connection); cmd.CommandType = CommandType.Text; cmd.Parameters.AddWithValue("@id", new system.Guid (imageid));//Failing Here!!!! connection.Open(); object img = cmd.ExecuteScalar(); try { return new MemoryStream((byte[])img); } catch { return null; } finally { connection.Close(); } } public bool IsReusable { get { return false; } } }

  • How to make my Java Swing application a Client-Server application?

    - by Jonas
    I have made a Java Swing application. Now I would like to make it a Client-Server application. All clients should be notified when data on the server is changed, so I'm not looking for a Web Service. The Client-Server application will be run on a single LAN, it's a business application. The Server will contain a database, JavaDB. What technology and library is easiest to start with? Should I implement it from scratch using Sockets, or should I use Java RMI, or maybe JMS? Or are there other alternatives that are easier to start with? And is there any server library that I should use? Is Jetty an alternative?

  • What library can I use to do simple, lightweight message passing?

    - by Mike
    I will be starting a project which requires communication between distributed nodes(the project is in C++). I need a lightweight message passing library to pass very simple messages(basically just strings of text) between nodes. The library must have the following characteristics: No external setup required. I need to be able to get everything up-and-running in my code - I don't want to require the user to install any packages or edit any configuration files(other than a list of IP addresses and ports to connect to). The underlying protocol which the library uses must be TCP(or if it is UDP, the library must guarantee the eventual receipt of the message). The library must be able to send and receive arbitrarily large strings(think up to 3GB+). The library needn't support any security mechanisms, fault tolerance, or encryption - I just need it to be fast, simple, and easy to use. I've considered MPI, but concluded it would require too much setup on the user's machine for my project. What library would you recommend for such a project? I would roll my own, but due to time constraints, I don't think that will be feasible.

  • Using svn remove - preserve file on disk instead of having it deleted?

    - by user246114
    Hi, I am creating an eclipse project, which generates a lot of files I don't want to keep under version control. For example, it creates a project folder like: project/ bin/ horse.class cow.class src/ horse.java cow.java so what I do is add the project folder to svn, like: svn add project this puts everything under control, even the bin and .class files. All of those files will have the little 'a' next to them. How can I simply remove the 'add' status from those files? If I try: svn remove bin/horse.class I have to use the --force option and it deletes the file from disk. Is there a way to simply remove it from source but not delete the file from disk? Thanks

  • TFS: Choose which workspace to add a solution too.

    - by Patricker
    I have a solution which I developed in VS2008 and which I am trying to add to Source Control (TFS 2010, though the issue happened in TFS 2008 as well). I have several TFS workspaces on my computer and I have access to several Team Projects. When I right click the solution in my Solution Explorer and choose the "Add Solution to Source Control" option I am never given an option of choosing which Workspace or which Team Project to add the existing solution too. VS2008 then proceeds to add it to the same team project every time. I have tried selecting an alternate workspace/team project in every window where I can see an option for it but it always adds it back to the same one. I even tried changing the name of my new workspace so that alphabetically it was the first thinking that it might be somehow related to that... no luck. I then tried goign to the Change Source Control window where you can add/remove bindings on a solution/project but that window also defaults to the same Team Project as trying to add the solution directly does... Any help would be greatly appreciated with this, maybe I'm just missing something?

  • Difference between ISupportInitialize (BeginInit/EndInit) and SuspendLayout/ResumeLayout

    - by Pato
    Hello All! Could someone please explain what the difference is between using the ISupportInitialize interface methods (BeginInit/EndInit) and using SuspendLayout/ResumeLayout? Is ISupportInitialize ONLY used during construction/"initial" initialization... or can it be used later when you want to add new child controls to an existing parent control? Any particular differences? I greatly appreciate your help! Thank you, Pato

  • What is the fastest way to write hundreds of files to disk using C#?

    - by Ehsan
    My program should write hundreds of files to disk, received by external resources (network) each file is a simple document that I'm currently store it with the name of GUID in a specific folder but creating hundred files, writing, closing is a lengthy process. Is there any better way to store these amount of files to disk? I've come to a solution, but I don't know if it is the best. First, I create 2 files, one of them is like allocation table and the second one is a huge file storing all the content of my documents. But reading from this file would be a nightmare; maybe a memory-mapped file technique could help. Could working with 30GB or more create a problem?

  • How to delay shutdown of an application when user logs off or shuts down Windows?

    - by badpanda
    I am writing an application that runs in the background from startup to shutdown, and in some circumstances I need the application to display a dialogue for the user to choose whether or not to continue shutting down. This application will only be running on Windows, but may be running on any version from 2000 onward. While I have certainly done some research on the topic, the information regarding the way that windows handles application shut down (http://msdn.microsoft.com/en-us/library/ms700677(VS.85).aspx) seems to be a bit scattered. If anyone has an example of the best way to handle this, or additional knowledge regarding the topic, I would very much appreciate it (I have very little experience with C#). Thanks!! badPanda

  • .net Drawing.Graphics.FromImage() returns blank black image

    - by joox
    I'm trying to rescale uploaded jpeg in asp.net So I go: Image original = Image.FromStream(myPostedFile.InputStream); int w=original.Width, h=original.Height; using(Graphics g = Graphics.FromImage(original)) { g.ScaleTransform(0.5f, 0.5f); ... // e.g. using (Bitmap done = new Bitmap(w, h, g)) { done.Save( Server.MapPath(saveas), ImageFormat.Jpeg ); //saves blank black, though with correct width and height } } this saves a virgin black jpeg whatever file i give it. Though if i take input image stream immediately into done bitmap, it does recompress and save it fine, like: Image original = Image.FromStream(myPostedFile.InputStream); using (Bitmap done = new Bitmap(original)) { done.Save( Server.MapPath(saveas), ImageFormat.Jpeg ); } Do i have to make some magic with g? upd: i tried: Image original = Image.FromStream(fstream); int w=original.Width, h=original.Height; using(Bitmap b = new Bitmap(original)) //also tried new Bitmap(w,h) using (Graphics g = Graphics.FromImage(b)) { g.DrawImage(original, 0, 0, w, h); //also tried g.DrawImage(b, 0, 0, w, h) using (Bitmap done = new Bitmap(w, h, g)) { done.Save( Server.MapPath(saveas), ImageFormat.Jpeg ); } } same story - pure black of correct dimensions

  • File.Exists() returns false, but not in debug

    - by Tor Haugen
    I'm being completely confused here folks, My code throws an exception because File.Exists() returns false public override sealed TCargo ReadFile(string fileName) { if (!File.Exists(fileName)) { throw new ArgumentException("Provided file name does not exist", "fileName"); } Visual studio breaks at the throw statement, and I immediately check the value of File.Exists(fileName) in the immediate window. It returns true. When I drag the breakpoint back up to the if statement and execute it again, it throws again. fileName is an absolute path to a file. I'm not creating the file, nor writing to it (it's there all along). If I paste the path into the open dialog in Notepad, it reads the file without problems. The code is executing in a background worker. It's the only complicating factor I can think of. I am positive the file has not been opened already, either in the worker thread or elsewhere. What's going on here?

  • Team Build Errors when there aren't any

    - by Jonesie
    I have a nightly team build that is reporting errors from the test step but zero errors in the summary. This results in a partial success. I cant see any errors in the full build log but maybe it's just the quantity of warnings?? Anyone got any ideas? Thanks

  • Is there an easier way to reconcile a list of files and a directory with subfolders/files to find ch

    - by rwmnau
    I have a SQL Server table with a list of files (path + filename), and a folder with multiple layers and files in each layer. I'm looking for a way to reconcile the two without having to process the list twice. Currently, I'm doing this: For Each f as FileInfo In FileListFromDatabase If f.Exists is False, mark it as deleted in the database Next For Each f as FileInfo In RecursiveListOFFilesOnDisk If Not FileExistsInDatabase, then add it Next Is there a better way to do this? I'd like to avoid converting all the matching files (of which most will be) to FileInfo objects twice. Since I'm a T-SQL developer first, I'm picturing something like an OUTER JOIN of the two lists where they don't match. Something LINQ-ish?

  • Moving Windows 7 OEM from one hard disk to another but retaining the rest of the hardware

    - by Dane
    I think this should be very easy but it doesn't seem like there's a whole lot of info out there. I've personally never done this exact maneuver because I've never needed to retain the OEM licence before. I have a laptop and I wish to simply swap out the hard disk with a bigger one but keep the Windows installation and files intact. Do I use Windows Backup and Restore and burn DVDs or do I just Acronis or something similar. Or is there an even easier way of doing this involving a third party desktop? Any help much appreciated.

  • What is good practice for writing web applications that control daemons (and their config files)

    - by Jones R
    Can someone suggest some basic advice on dealing with web applications that interact with configuration files like httpd.conf, bind zone files, etc. I understand that it's bad practice, in fact very dangerous to allow arbitrary execution of code without fully validating it and so on. But say you are tasked to write a small app that allows one to add vhosts to an apache configuration. Do you have your code execute with full privileges, do you write future variables into a database and have a cron job (with full privileges) execute a script that pulls the vars from the database and throws them into a template config file, etc. Some thoughts & contributions on this issue would be appreciated. tl;dr - how can you securely write a web app to update/create entries in a config file like apache's httpd.conf, etc.

  • Using Visual Studio 2010 Express to create a surface I can draw to

    - by Joel
    I'm coming from a Java background and trying to port a simple version of Conway's Game of Life that I wrote to C# in order to learn the language. In Java, I drew my output by inheriting from JComponent and overriding paint(). My new canvas class then had an instance of the simulation's backend which it could read/manipulate. I was then able to get the WYSIWYG GUI editor (Matisse, from NetBeans) to allow me to visually place the canvas. In C#, I've gathered that I need to override OnPaint() to draw things, which (as far as I know) requires me to inherit from something (I chose Panel). I can't figure out how to get the Windows forms editor to let me place my custom class. I'm also uncertain about where in the generated code I need to place my class. How can I do this, and is putting all my drawing code into a subclass really how I should be going about this? The lack of easy answers on Google suggests I'm missing something important here. If anyone wants to suggest a method for doing this in WPF as well, I'm curious to hear it. Thanks
