  • Unexpected cross threading issue

    - by haughtonomous
    I'm trying to do something very simple in principal, but I keep getting a cross-threading exception which has me stumped because I'm not setting out to use multiple threads. I have a Windows Forms application. It launches another Windows Forms application (using the System.Diagnostics.Process class) , and catches the Exited event when that application is closed. My application event handler then tries to copy text from the clipboard to a control on the current displayed form. At this point a Cross-threading exception is thrown. I assume that the problem is that the event from the closing application is in another thread (I'm outside my comfort zone here, so bear with me), so the question boils down to "How do I prevent this exception?" I'm somewhat constrained into having to copy from the clipboard, but I could launch the other application a different way if that would solve the problem.

  • Silverlight horizontal stretch and get position issue

    - by David
    I have a Grid (container) wich in turn has several grids(subContainers) arranged by rows. Each one of those "subContainers" has diferent columns and controls. And each of those "subContainers" has the horizontal alignment set to stretch, and it has to stay that way, since the layout this viewer depends on it. I use the "container" to set each control on it's adequate position. So far so good. Now comes my headache... I want to remove the control from the grid and put it in a canvas, at the same exact position, only, the position it returns is as if the control is set to the beggining of the grid and not it's true position. For testing purposes, I've set the "subContainters" horizontal alignment to center and (despite the layout is totally wrong) every control is in it's right position when sent to a canvas, wich it doesn't happen when HA = stretch. Here's the code I'm using to get position: GeneralTransform gt = nc.TransformToVisual(gridZoom); Point offset = gt.Transform(new Point()); So you can understand, for example, my first control should be somewhere like (80, 1090), but the point that I get is (3,3). Can anyone help me? Thanks

  • VB.NET class inherits a base class and implements an interface issue (works in C#)

    - by 300 baud
    I am trying to create a class in VB.NET which inherits a base abstract class and also implements an interface. The interface declares a string property called Description. The base class contains a string property called Description. The main class inherits the base class and implements the interface. The existence of the Description property in the base class fulfills the interface requirements. This works fine in C# but causes issues in VB.NET. First, here is an example of the C# code which works: public interface IFoo { string Description { get; set; } } public abstract class FooBase { public string Description { get; set; } } public class MyFoo : FooBase, IFoo { } Now here is the VB.NET version which gives a compiler error: Public Interface IFoo Property Description() As String End Interface Public MustInherit Class FooBase Private _Description As String Public Property Description() As String Get Return _Description End Get Set(ByVal value As String) _Description = value End Set End Property End Class Public Class MyFoo Inherits FooBase Implements IFoo End Class If I make the base class (FooBase) implement the interface and add the Implements IFoo.Description to the property all is good, but I do not want the base class to implement the interface. The compiler error is: Class 'MyFoo' must implement 'Property Description() As String' for interface 'IFoo'. Implementing property must have matching 'ReadOnly' or 'WriteOnly' specifiers. Can VB.NET not handle this, or do I need to change my syntax somewhere to get this to work?

  • String Sharing/Reference issue with objects in Delphi

    - by jenakai123
    My application builds many objects in memory based on filenames (among other string based information). I was hoping to optimise memory usage by storing the path and filename separately, and then sharing the path between objects in the same path. I wasn't trying to look at using a string pool or anything, basically my objects are sorted so if I have 10 objects with the same path I want objects 2-10 to have their path "pointed" at object 1's path (eg object[2].Path=object[1].Path); I have a problem though, I don't believe that my objects are in fact sharing a reference to the same string after I think I am telling them to (by the object[2].Path=object[1].Path assignment). When I do an experiment with a string list and set all the values to point to the first value in the list I can see the "memory conservation" in action, but when I use objects I see absolutely no change at all, admittedly I am only using task manager (private working set) to watch for memory use changes. Here's a contrived example, I hope this makes sense. I have an object: TfileObject=class(Tobject) FpathPart: string; FfilePart: string; end; Now I create 1,000,000 instances of the object, using a new string for each one: var x: integer; MyFilePath: string; fo: TfileObject; begin for x := 1 to 1000000 do begin // create a new string for every iteration of the loop MyFilePath:=ExtractFilePath(Application.ExeName); fo:=TfileObject.Create; fo.FpathPart:=MyFilePath; FobjectList.Add(fo); end; end; Run this up and task manager says I am using 68MB of memory or something. (Note that if I allocated MyFilePath outside of the loop then I do save memory because of 1 instance of the string, but this is a contrived example and not actually how it would happen in the app). Now I want to "optimise" my memory usage by making all objects share the same instance of the path string, since it's the same value: var x: integer; begin for x:=1 to FobjectList.Count-1 do begin TfileObject(FobjectList[x]).FpathPart:=TfileObject(FobjectList[0]).FpathPart; end; end; Task Manager shows absouletly no change. However if I do something similar with a TstringList: var x: integer; begin for x := 1 to 1000000 do begin FstringList.Add(ExtractFilePath(Application.ExeName)); end; end; Task Manager says 60MB memory use. Now optimise with: var x: integer; begin for x := 1 to FstringList.Count - 1 do FstringList[x]:=FstringList[0]; end; Task Manager shows the drop in memory usage that I would expect, now 10MB. So I seem to be able to share strings in a string list, but not in objects. I am obviously missing something conceptually, in code or both! I hope this makes sense, I can really see the ability to conserve memory using this technique as I have a lot of objects all with lots of string information, that data is sorted in many different ways and I would like to be able to iterate over this data once it is loaded into memory and free some of that memory back up again by sharing strings in this way. Thanks in advance for any assistance you can offer.

  • Cannot connect via HTTPS in Java app on MacOSX (Certificate validation issue)

    - by johnnyx
    I have a java application that connects to a webservice over https. The domain where i host the webservice has a valid Goddaddy issued SSL certificate. The application works fine on Windows but on MacOSx i receive the following exception when attempting to connect to the webservice via https. sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target I've tested it on two machines running Mac OS X 10.7.2 with the latest java runtime updates. I understand this is usually a problem with self signed certificates that need to be added manually, but i have a valid Godaddy issued certificate. In webbrowsers (safari & firefox) on mac os the certificate is recognized and seems ok. I even tried adding the certificate to the key chain manually like in the gase of a self signed one but to no result.

Any idea why? Where is it going after the event is handled?

  • C# TCP Client/Server communication issue

    - by Jamie
    What i'm currently trying to do is make a very basic webchat for irc using silverlight. Basically how i'm trying to do it is have a tcp server listening for connections from silverlight. When a client connects it creates a new connection to irc and data is passed to/from the client/irc via the server application. I've gotten it to work fine for one client connection, but as soon as two (or more) clients connect multiple connections are made to irc but all data passed from the clients just goes through the latest irc connection (if that makes sense). For example Client1, Client2 and Client3 are all connected to irc, but no matter who sends data it all comes through Client3. Between the client and server app it recongises the data coming in from different clients so i believe the problems lies within the way i've connected to the irc. When the TCP server accepts a new client a new thread is made to listen to incoming data, and from there a new thread is made to connect to irc. I'm sure thats where the problem exists, but i've confused myself a lot now and am wondering if anyone can help me figure out a solution.

  • Source control issue with deploying versions

    - by Bonefisher
    Hi all, we have this discussion about how to deploy to production revisions that are UAT closed without revisions with UAT not-closed status. We are using SVN and we figured out that we are not able to just take revisions without prior-revisions on the same file made. Let me explain it on this example: we have 3 revisions made on same file: r1: UAT closed (ready to deploy) r2: UAT not-closed (not ready) r3: UAT closed (ready to deploy) now I want to deploy only my changes for which the UAT is closed (e.g. r1 and r3). In SVN this is not possible because r3 contains also r2 changes.. How do you made this to work? Maybe branching? Or just take r1 and wait until r2 is UAT closed? thanks

When I comment out the 2nd if statement, the problem works fine. So I suspect the way I am performing bitwise operations for 64bit data is incorrect. Can anyone see anything in this code that needs to be corrected?

  • issue running a batch script to kill a process

    - by user657064
    I am using the following script on a command line to kill a hypothetical notepad process (using a Korn shell in Windows XP, if that matters): kill $(tasklist | grep -i notepad.exe | awk '{print 2}') Now I take this line, and put it into a batch file c:\temp\testkill.bat, thinking that I should just as well be able to kill the process by running the batch file. However, when I run the batch file, I get the following awk error about unbalanced parentheses: C:/Temp ./testkill.bat C:\Tempkill $(tasklist | grep -i notepad.exe | awk '{print $2}') awk: unbalanced () Context is: {print $2}) <<< C:/Temp So I'm baffled as to why I am getting this error about unbalanced parentheses when I run this script via a batch file, but have no issues when I run the command directly from the command line? (Btw, I'm not necessarily tied to this way of killing a process - as a total noob to shell scripting, I am additionally wondering why if I write the following on the command line: tasklist | grep -i notepad.exe | awk '{print $2}' | kill the process ID that comes out of the tasklist/grep/awk calls doesn't seem to properly get piped to kill...)
