    - Image processing application If i had to develop a windows forms based application , that would be used for viewing a running video in one window, freezing an image from the video into another window based on user's choice, and then change the resolution, position, color intensity and zoom of the frozen image, what should i be using ? C# and Win 32 ? Or Just C# ? Or VC++.NET ? (Or MFC / ATL ?). Please advise , since i have only used C# for data driven application so far, and would have to learn the other technologies for this application. Regards, Chak.

    - Is the Threadpool useless ? I have a problem with the threadpool I can't seem to figure out. If I use ThreadPool.QueueUserWorkItem to queue say 25 work items, I would expect the Threadpool to give me the 25 free threads of the thread pool i.e. execute my WaitCallback method 25 times instantly. However, there seems to be about 0.5 sec. delay in pulling each thread of the queue. Running the test code public void WaitCallback( object state ) { System.Diagnostics.Debug.WriteLine("Thread "+((int)state).ToString()+" started"); Thread.Sleep(10000); } for( int i =0; i<50; i++) ThreadPool.QueueUserWorkItem(new WaitCallback(WaitCallback),i); I would expect the threadpool to instantly give me all available threads thus executing the WaitCallback method 25 times. However, it takes at least 25 seconds for the pool to kick off 25 threads. If you do not get the threads immediately, this in my book would make the Threadpool completely useless for server purposes and any other for that matter. Is this as designed or am I doing something wrong ? Regards Per Millard Systems Architect Copenhagen Denmark Tag: .NET controls running in Internet Explorer Tag: 102511

    - Problem with .Net app using 25% cpu Hi! I am developing a .Net app and I have got some problems with the program suddenly using 25% cpu... The strange thing is that my program is not doing anything(as far as I can tell), and the UI is just as responsive as ever, even though it's single threaded (shouldn't it get a little sluggish??), leading me to believe the problem must lie in a thread I don't controll (GC????) . The program will keep using 25% cpu until shutdown, when restarted it can work satisfactory (about 1-2% cpu) for anything between 10 minutes to 10 hours before the problem reappears. Using a process viewer I have found the faulting thread to be spending time in mscorwks.dll!ReleaseFusionInterface, anyone know what this is??? Any help would be greatly appreciated Sincerley Rune Lanton Transportnett AS Tag: .NET controls running in Internet Explorer Tag: 102507

    - Binding a datagrid to a System.Collections member Ok, all I am doing is trying to bind a data grid to an IDictionary. Here goes: Sub Page_Load(sender As Object, e As EventArgs) If Not IsPostBack() Then Call BindData() End Sub Public Sub BindData() Dim Skl As New Hashtable Skl.Add(1, "Visual C#") skl.Add(2, "Visual Basic") skl.Add(3, "Win32 API Programming") dg.DataSource = skl dg.DataBind() End Sub The error I get is: System.Web.HttpException: DataGrid with id 'dg' could not automatically generate any columns from the selected data source. on the line: dg.DataBind() So, is there some special glue when you have to bind a datagrid to a non-relational source such as IList or IDictionary or Hashtable?

    - Converting Tif to Jpeg problem (Sorry for the double post I just saw the naming required for themanged newsgroup and I need an answer!! Thanks) Hi, I'm writing an application that extract attachment from Exchange, save it in an SQL DB and then display it over the web. Everything works fine for JPG, GIF, etc. However for TIFF file I need to convert them. However my code does not seem to work... I can convert from JPEG to GIF but not from TIFF to GIF or JPEG. For some reason the converted TIFF image appears to become corrupted during the conversion... The resulting JPEG image shows an empty large image holder. If I "re-convert" (or if you prefer "re-save as a JPEG") a second time the image again before displaying it, then it shows a portion of the image but then seems to repeat a "pixel row" indefinetely till the bottom... Any idea has to what I'm doing wrong? Thanks a lot for your help. Here is the code I use: //Converts the bytes extracted from the exchange attachment //Note: I tried using a file instead of memory stream with the same results public byte[] ConvertTiffToJpeg(byte[] tiffImage) { //Creating memory stream with the raw image data System.IO.MemoryStream memStrm = new System.IO.MemoryStream(tiffImage, true); memStrm.Write(tiffImage, 0, tiffImage.Length); //Create an image from the memory stream System.Drawing.Image img = System.Drawing.Image.FromStream(memStrm, true, false); //Get the list of available encoders System.Drawing.Imaging.ImageCodecInfo[] codecs = System.Drawing.Imaging.ImageCodecInfo.GetImageEncoders(); //find the encoder with the image/jpeg mime-type System.Drawing.Imaging.ImageCodecInfo ici = null; foreach (System.Drawing.Imaging.ImageCodecInfo codec in codecs) { if (codec.MimeType == "image/jpeg") ici = codec; } //Create a collection of encoder parameters (we only need one in the collection) System.Drawing.Imaging.EncoderParameters ep = new System.Drawing.Imaging.EncoderParameters(); //Create an encoder parameter for quality with an appropriate level setting ep.Param[0] = new System.Drawing.Imaging.EncoderParameter(System.Drawing.Imaging.Encoder.Quality, (long)100); //Convert the tiff image to jpeg and save the result to a new memory strem System.IO.MemoryStream convertedMs = new System.IO.MemoryStream(); img.Save(convertedMs, ici, ep); //Convert the jpeg image back to byte return convertedMs.ToArray(); } -- Martin Rajotte Incycle Software Tag: .NET controls running in Internet Explorer Tag: 102428

    - Enterprise Library - Asynchronous Logging... I have managed to get asycnhronous logging work for an asp.net application and I wanted some clarification on the method. Normally if the application is logging synchronously it has all the settings for the logging application block in the app.config for the application. But if you want to use asynchronous logging you have to specify asynchronous logging for all logging types in the app.config of the application and then define the extact logging sinks in the app.config of the msmqdistributor.exe (windows service). Is this correct? Seems rather confusing and rather messy - application specific logging information have to be put into a generic widows service that could be used by more than one application on the system. cheers Ollie Riches Tag: .NET controls running in Internet Explorer Tag: 102382

    - Difference in XML serialization between Win 2000 and Win XP ? Hi, I'm getting some very odd (to me atleast) results when writing a serialized object to disk as an xml file. It works correctly in WinXP but not in Win 2000. This is the code: XmlSerializer x = new XmlSerializer( typeof(OptionsHolder) ); TextWriter writer = new StreamWriter( "serversettings.xml" ); x.Serialize( writer, opt ); writer.Close(); and the object has the following class: public class OptionsHolder { public int timeout; public string lastrapportdate = ""; public string lastprintdate = ""; public bool deleteNonConfirmed = true; public string defaultProject = "obevakad"; public string [] watchprinters; // = new string[256]; // Max 256 skrivare på en server public string [] dontwatchprinters; // = new string[256]; // Max 256 skrivare på en server public string [] ignoreips; // = new string[256]; // Max 256 klienter kan ignoreras public OptionsHolder() { } } On Win 2000 it just refuses to write whatever string is currently present in lastrapportdate. I have verified that there is content in the variable before serializing. All other items get dumped to disk.

    - Hashtable thread safety? It doesn't seem completely clear to me which operations I can perform while continuing to be thread-safe on a Hashtable. Consider this scenario: Hashtable 'table' contains the following: table[1] = 1 table[2] = 2 table[...] = ... table[Int32.MaxValue] = Int32.MaxValue The following threads are now running against that same table Thread 1: for( int i = -1; i > Int32.MinValue; i-- ) { table.Add( i, i ); } Thread 2: for( int i = 1; i < Int32.MaxValue; i++ ) { table.Remove( i ); } Thread 3: while( true ) { IList list = new ArrayList( table.Keys ); foreach( int number in list ) { Console.WriteLine( number ); } } Obviously this is unusual, but it's something like what I actually have, and I want to know whether or not this is thread-safe or if I need to provide some synchronization.

    - SocketException ??? Hi. I have some quite unusual situation at which SocketException is thown while connecting a socket. Generally the aim of application is processes data and send results to a specified IPEndPoint. Since theres small amount of time for processing and sending large amount of data it is logical to split whole process in to few threads. One thread processes data and other sends it. The problem occures when user sets too little time for doing that. At first the thread works fine for about a minute or two, results are being received on another machine event when the speed of whole process is considered to be critical. And then just like that, exception SocketException is thrown while connecting to an IpEndPoint with message that might be translated as "It is usually allowed a single use of socket address". As seen below socket is being shutdown and closed in the end. And it seems like theres absolutely no reason for that exception to catch. Any propositions? Thank you. Error code of exception is 10048 private void Operate() { while (/*There is data to send*/) { Socket socket = null; try { socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); socket.Connect(ipEndPoint); <--------------------------------------------------------------------------Exception: SocketException thrown here !!!!!!!!!!!!!

    - SqlException: Unknown Error I have some code doing a very simple select "select bonusid from game where gameid=@gameid" that works about 98% of the time, but somewhere around two percent of the time it throws an exception. If I go through the sqlerror's in the exception all it has is the following: Index #0 Message: Unknown error. LineNumber: 0 Source: .Net SqlClient Data Provider Procedure: Not very interesting is it. I've checked that the input is valid and I have no problems running the same query manually. I also have yet to find a consistent way to recreate this error but my clients are having no problems doing it fairly frequently with no rhyme or reason that I can tell. Although there are many clients simultaneously using the server they share one database connection but I am very careful to only use the connection through a wrapper class that Lock()'s the database connection. I'm really lost on this one, has anyone else seen this? I could find next to nothing on google/google groups. Lloyd Christopher SLOW30 Tag: .NET controls running in Internet Explorer Tag: 102325

I will told you all my sad history, I had installed in my computer the enterprise library of june with the ilussion than that will keep me away from the database connections problems, scalability problems, and all that things!, and I had tested that in my developer machine, and I dont had these problems, but when I had started to setup the server, wow, what a fu"#$%#$#$!"cking problem, the assemplies of the Enterprise Library doesn't work. I had runned without results the installutil for each assembly, I had compiled in command line the source code of these blocks in the server and i dont had results, i had do everything possible (but not install the Visual Studio 2003), and i dont have positive results. Hey Microsoft guys, what is the problem with yours??, Keep it simple, why the DAAB had worked so good, so easy, and with that enterprise library everithing had changed, and you had send us a stupid problem. For all you gouys, the problem than I got is that message error: The type initializer for "Microsoft.Practices.EnterpriseLibrary.Data.Instrumentation.DataConnectionFailedEvent" threw an exception.

    - SQL Server Mobile on Tablet PC I'm trying to load data on a SQL Server CE database. Doing it on the Pocket PC takes very long. I though I'd load it on the desktop using the tablet PC API, using Visual Studio 2005 Beta 2 and Sql Server 2005 (Mobile). I'm following instructions provided in the help file for Sql Server 2005 - "Building a SQL Server Mobile Application for Tablet PCs". I'm having 2 problems. 1. I can't find "Microsoft Tablet PC API" under .NET assemblies, to add a reference. 2. I did the rest - added "System.Data.SqlServerCe.dll" as a reference. The application builds fine, but when it runs, it immediately stops with this error: System.IO.FileLoadException was unhandled Message="Could not load file or assembly 'System.Data.SqlServerCe, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies.

    - server side http for a non-web server I'm evaluating using http to carry data between a client and a non-web (C#) server application. This sounds great as the browser already has an http implementation and http is an open protocol. I was expecting to find a server piece that implemented the server side without requiring a full web server. I've looked around and found http.sys which sounded ideal but which doesn't seem have a C# API until Framework 2.0. Is anyone aware of either some kind of a C++ wrapper for http.sys or an alternate http implementation? If not, I can fairly readily build a wrapper on top of existing TCP functionality but I believe in reusing software when possible. I could also introduce IIS and create an ASP.NET "proxy" that could take http POSTS and relay them in the existing TCP format. Thanks Mike Tag: .NET controls running in Internet Explorer Tag: 102317

    - asynchronous logging with enterprise library logging application block. I am trying to use asynchronous logging using MSMQ and I have configured the properties as defined in the help (see below) I don't understand where the property 'MsmqPath' is in the app.config for MSMQDistrbutor.exe is it meant to be an aplication settings or an enterprise library setting in the app.config? I have tried creating an application setting value for it but it still fails to write to the logging destination? Also is this meant to be registered as a service? To choose asynchronous logging. 1.. In the Enterprise Library Configuration Console, expand Client Settings, right-click Distribution Strategies, point to New and then click MSMQ. 2.. Select the strategy and then specify the QueuePath for the strategy. 3.. Select Client Settings, and then modify the DistributionStrategy property to select the MSMQ distribution strategy you created. 4.. Open the MSMQDistributor.exe.config file with the Configuration Console, located in the directory containing the file MSMQDistributor.exe. Modify the MsmqPath property of the MSMQ Distributor Service to match the QueuePath property of the MSMQ distribution strategy you selected in step 2. This distribution strategy will be used for all messages that are not filtered out. Note Do not use the In Process distributor strategy and the MSMQ distributor strategy to log to the same flat file sink. Using both the In Process and MSMQ distributor strategies with the same flat file sink may result in simultaneous attempts to write to the same file. This will result in failure due to the file resource being in use by another process. Has anyone got any ideas? I followed the instructions below to allow for an MSMQ not registered with AD. http://mvwood.com/blogs/blog/archive/2005/03/04/321.aspx Cheers Ollie Riches Tag: .NET controls running in Internet Explorer Tag: 102316

    - Monitoring the existence of multiple files What's the best way to monitor an arbitrary set of files? In a program like a CD burning app, you've got a an explorer-like file system listview that you pick your files from and a listview for the CD compilation. If you populate the CD listview with 100 different files from 100 different folders, is there a good way to monitor any changes to the files in that listview (deletions, renames, moves, etc.)? This is mostly a GUI thing. I can easily check the existence of the files just prior to performing any operations on them, but I'd like to provide realtime feedback to the user so that they know when one of the files they've chosen is unavailable. I know there's the FileSystemWatcher class, but I suspect it's unwise to create 100 FSWs, each monitoring one file per directory. Tag: .NET controls running in Internet Explorer Tag: 102314

Hi,
our system is running .NET controls hosted in Internet Explorer. Everything
was fine up to the moment when we started to get messages: "the publisher
could not be verified", browsing the pages having these ".NET applets"
inside. The message keeps repeating each time I enter the page, user needs
to press 'Run' on the messagebox prompting.

I went to lower the security setting for the browser and dotnet:
- adding the site to trusted sites
- enabling all dotnet/activex/java downloading/executing
- making checks in registry (e.g.
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Download)
- i tried to sign controls giving them a strong name - no change

I'm running Windows XP professional version 2002 Service Pack 2. This is the
only version facing this problem (maybe this 'version 2002' causes this). On
other machines I'm using SP2 for XP pro for a year without any problems.

Our .NET controls of course do not have any certificate (they're not
approved by any VeriSign like agency)
- system i working in LAN only!
- we would like to avoid unneeded costs
- would this surely help anyway?
- could thi sthing be solved using test certificate (using cert2spc.exe?)

Any clue? Anybody facing this problem?

Igor Kramaric, dev.engineer

P.S. I found many articles addressing the security issues ragrding SP2 on
XP, none of them is focusing on .net controls in IE
