    - Third-party help files not integrating with main .net help files I have a third-party grid control that I am using. I installed it just like I have done with other third-party controls that I have. Usually after I install the control, and access help for the first time from the IDE, I get a message saying that help is updating to reflect recent changes, but I don't get it with this control so I cannot access help for it. It is a .NET control and has all the correct help files (not .CHM files). How can I force the controls help files to intergate with .NET help? Thanks in advance! Tag: How to play an audio file?

    - Console vs Service Application I'm writing an application that needs to run every x minutes, read in some data from a log file and then write it out to a database. Originally I was going to write it as a service but the more I think about it I feel it would work just as well as a console application that is scheduled using the Windows scheduler. I'm just curious as to whether there are any other advantages to using a service that I might not have thought of? Here are some reasons why I thought a console application would be acceptable: 1. It is easier to schedule the console application using the Windows scheduler or 3rd party scheduling applications, using a service I would need to write scheduling code into it 2. It doesn't matter if the application is manually run between scheduled periods 3. It could be handy to write output to the console so if someone manually runs it that can see what is happening Any thoughts would be greatly appreciated. William D.

    - Empty columns when exporting to excel from crystal reports Hi, I tried this demo application in here (watch for any line breaks in the URL): (http://support.crystaldecisions.com/communityCS/FilesAndUpdates/vbnet_win_a dodotnet.exe.asp When exporting to Excel there is an empty column after each actual column in the excel. Why? Is this a normal behaviour? Is it impossible to get rid of the empty columns when using the export funtion of the report? Please clarify me so that I can decide to either use the export functionality of the report or to implement my own excel export. I rather use the export functionality of the report itself if I can get rid of the empty columns. -- Thanks in advance Ali Eghtebas Sweden Tag: How to play an audio file? Tag: 56879

    - Question: How do you retrieve Properties provided by an ExtenderProvider through reflection? Hi, I've written a simple ExtenderProvider that provides a string property (Let's call it CustomStringProperty) to all the buttons on a form. The ExtenderProvider itself is placed on a base form (It is protected, so derived forms will inherit it's functionality) and provides the CustomStringProperty to all forms derived from it. It's canonical and works well. It allows the values to be assigned during design time. Thereby easing the development of new forms and insuring that all the buttons on new forms (that derive from the base form containing the ExtenderProvider) have the CustomStringProperty. Now I'm writing a small external tool that is attempting to extract these CustomStringProperty(s) through reflection and log their value in a database. However, It's my understanding that the values of the CustomStringProperties are assigned during the InitializeComponent() method call of the associated forms (which to my knowledge doesn't get executed during reflection). And I don't think that the properties extended by the ExtenderProvider show up in the fieldinfo of the buttons themselves, rather that you must go throught the ExtenderProvider during runtime. Am I wrong? Any advice would be welcome. Thanks Jason Tag: How to play an audio file? Tag: 56878

    - efficient C# coding I'm looking for a good article on efficient C# coding. All the DotNet efficient coding articles I can find are oriented toward VB.NET, and while some principals still apply, many do not. For instance there is no equivalent of with (some object) . end with in C# (or somebody straighten me out). Somehow in the my early studies of C# I got the (apparently wrong) impression that it had some kind of great compiler that made all the good practices I learned in VB unnecessary. Consider the following: private static void LoadHeadings(UltraWebGrid Grid, XmlNode[] PrevHeadingArray, SortedList FootnoteList, int CurRow) { for (int i = 0; i < PrevHeadingArray.Length; i++) { Grid.Rows[CurRow].Cells[i].Text = PrevHeadingArray[i].Attributes["text"].Value + SuperFootnotes(PrevHeadingArray[i].SelectNodes("child::note"), FootnoteList); Grid.Rows[CurRow].Cells[i].Style.VerticalAlign = VerticalAlign.Top; } } I need to access the same cell twice, and I do it down a fairly long path. Nowhere have I seen it advised to assign the object to a local variable and then access it, yet when I did that the following code generated considerably less code in the debugger disassembly: private static void LoadHeadings(UltraWebGrid Grid, XmlNode[] PrevHeadingArray, SortedList FootnoteList, int CurRow) { for (int i = 0; i < PrevHeadingArray.Length; i++) { UltraGridCell oCell = Grid.Rows[CurRow].Cells[i]; oCell.Text = PrevHeadingArray[i].Attributes["text"].Value + SuperFootnotes(PrevHeadingArray[i].SelectNodes("child::note"), FootnoteList); oCell.Style.VerticalAlign = VerticalAlign.Top; } } I can't really interpret the assembler code, but I figure less code is usually a good proxy for more efficient code. Judging from my VB experience the next step would be to assign "PrevHeadingArray.Length" to a local integer. Am I on the right track? I really don't have the time to pursue these interesting investigations, and I haven't taken the time to instrument the example above and see what the comparative elapsed times are, I would much rather read this all spelled-out somewhere.

    - Read from COM port? I need to read messages from a device connected to a COM port with the following format: When the controller is configured to report events, it will transmit a new message every time the event occurs. The message follows the following format: XX <Message> {CR} {LF} {Terminator} . "XX" is the Message ID Number. Each type of report message from the controller has a unique ID number in a 2-digit hexadecimal format. Each digit will be a hexadecimal value (numbers 0-9 or letters A-F). When converted to decimal format, they represent the numbers 0 through 255. By reading these two bytes, a user program can quickly identify the type of message from the controller. . "<Message>" will contain a text description of the event. . {CR} signifies that a carriage return is sent. . {LF} signifies that a line feed is sent. . {Terminator} signifies that a single-byte terminator code is sent. The byte has a value 1d, which is the ASCII code SOH (this is NOT the number 1, which is ASCII value 49d). The terminator is provided to make it easier for a computer program to read and interpret the messages from the controller. What framework clases are best suited for reading this kind of messages from the device? Can you specify the terminator character which is at the end of each message? -- Olav Tollefsen Tag: How to play an audio file? Tag: 56862

Perusing various search engines has turned up nothing except for a single webboard thread which talked about msn.jp and someone's theory that it is a personal .NET extenstion system for MSN.com because you can easilly create your own extensions.

    - ADO.net Hey, i am bit concerned about the architecture provided in the .net frame work for ado.net. The disconnected architecture does nor serves you best on the desktop application. As you are not connected to database and if any other changes the table in the database you are not notified or your side data is still older one. As it was not in ADO we use to set the recordset properties to our need and we were quite happy. but not now. Example: Dim rs as ADODB.Recordset TextBox1.databindings.add("Text",rs,"id") (X) which is not allowed by the .net frame work, as i am using the Recordset that is in ADO not in ADO.Net and its required interface is not present. But i want to do that ... as it is quite easy to use this structure. I think there is problem with Microsoft they dont even support there ADO properties in their .net TextBox or any other control. They should provide the Implementation of connected recordset or simply implement the IList interface or any other interface that is required for the data binding in .net fram work. thanx, Rizwan Ahmed Tag: How to play an audio file?

    - TcpClient lost data timing anomaly Hi The platform: XP/pro on a dual Xeon 3GH processors I am using TcpClient class to communicate with a POP3 server. Short problem synopsis: a 'read' hangs even though there is data in the buffer (as evidenced by a network sniffer trace). Elaboration: I/O is done by getting the NetworkStream and doing a read for a whole buffer's worth (typically 1024) of bytes. The code looks for the NL (new-line char, '\n'), as a delimiter. If found, the text up to and including the NL is returned to the caller. Otherwise another read is performed and concatenated to the previous read's output, and the check for the delimiter repeats. On subsequent reads, if there was data left over from the previous read, it is processed for NL before any other reads are issued. I have used a network sniffer to determine that all the data is coming in. I have put a trace in my program to output to a file (serialized with a 'lock') all the output form all the read requests. I consistently find that one of the reads is able to get all but the last 3 bytes of a response from a server. The code dutifully returns all the text received and tries to do another read since the caller is looking for a '.\r\n' sequence (end-of-message). This read hangs (I use the debugger). When I change the buffer size the problem happens in a different message. If I make the buffer large enough, the problem goes away. The buffering code described above is working for thousands of messages that have split across multiple buffers or for short messages where multiple fit in the same buffer, so I'm pretty confident that it is splitting messages correctly and gluing together segments across network messages. My only conclusion is that something in the TcpClient (or deeper) is checking the socket and waiting for more data in a non-atomic manner. The problem shows up on my system because it is a fast dual processor system that can obviously do concurrent processing by multiple threads/processes. Has any one seen this kind of problem before? Any work-around? -TIA David Tag: How to play an audio file? Tag: 56822

    - Problems with GCHandle and AppDomains Greetings everyone. I am currently working on a multimedia application written in unmanaged code. As part on my next set of improvements, I would like to host the CLR in the application and allow third parties to extend the application and manipulate internal objects in the application through a "script" interop layer I provide written (on my end) in managed C++. The way my system is set up, from the default domain in my host, I instantiate the script harness using AppDomain::CreateInstanceAndUnwrap method and downcast the resulting object to a common interface that my application and the harness know about. I call a "run" method on the interface. In a test script I created, I register a callback object into the multimedia app. The unmanaged callback object contains a GCHandle to a delegate which it fires periodically on behalf of the unmanaged application based on certain timing parameters. Now, when the harness and my test script used to run in the default domain, everything worked like a champ. Now that the test script is in a different domain, when the unmanaged callback object dereferences the gchandle to invoke the delegate on the script, I get an ArgumentException with a description that reads: "Cannot pass a GCHandle across app domains". I've hit my head against the wall trying to get this to work for a while now with no success. Does anyone have any idea what I could be doing wrong? Thanks in advance for any help you can give.

    - Localization and multiple string resources Hello! I am looking at .Net localization. I happen to be using J# with VS 2003 but it could be any supported language. The LocalizedHelloWorld example from MSDN and VS shows how to localize a single .resources file. Here is a link to the J# version: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_vjsample/html/vjsamlocalizedhelloworldsamplesatelliteassembliesforconsoleapplications.asp The problem I have is I am working with an application that has several string resources per DLL. I have not been able to find a way to get it to work. The example loads a resource called "HelloWorld.Resources.MyResources". Each localized version is embedded in a DLL called "HelloWorld.resources.DLL". The trick seems to be that there can be only one such DLL. I have modified this sample and tried embedding two resources, MyResources.resources and MyResources2.resources, and also creating, for example, two French resources, MyResources.fr.resources and MyResources2.fr.resources, into the satellite assembly "HelloWorld.resources.DLL". But, when I request "HelloWorld.Resources.MyResources2" with the culture set to "fr", it fails to find the second French resource and falls back to the embedded MyResources2.resources. Does anyone know a way to make this work? Thanks in advance. Tag: How to play an audio file? Tag: 56803

    - Base Class Prop not hidden to Reflection Hello, I'm encountering an unexpected behavior when using the "new" modifier in a derived class to hide an inherited base class property. I use "new" intentionally so I can change the Type of the property in the derived class, and I can use the derived class as expected through standard instantiation. The unexpected behavior occurs when I try to set gather the PropertyInfo for the derived class property via Reflection. I get an AmbiguousMatchException as both the base class and derived class property implementations are found. Perhaps I don't fully understand the "new" modifier - I expected the base class member to be hidden completely when working with the derived class. I have included a code sample that illustrates the behavior. If anyone could explain this, I would be very interested in understanding. Thanks. using System; using System.Reflection; namespace TestHide { class foo { [STAThread] static void Main(string[] args) { Derived d = new Derived( "test" ); Console.WriteLine( "PropType:\t" + d.Problem.GetType().ToString() ); try { PropertyInfo p = d.GetType().GetProperty ( "Problem" ); } catch(AmbiguousMatchException e) { Console.WriteLine( "Error:\t\t" + e.Message ); PropertyInfo[] p = d.GetType().GetProperties(); for( int n = 0; n < p.Length; n++ ) { Console.WriteLine( "Name: " + p[n].Name + "\tType: " + p[n].PropertyType + "\tDecl: " + p[n].DeclaringType ); } } catch(Exception e) { Console.WriteLine( e.Message ); } } } public class Base { protected int _works = 0; protected object _problem = null; public Base(){} public virtual int Works { get { return _works; } set { _works = value; } } public virtual object Problem { get { return _problem; } set { _problem = value; } } } public class Derived : Base { public Derived(){} public Derived(string problem) { this.Problem = problem; } public override int Works { get { return base.Works - 1; } set { base.Works = value + 2; } } public new string Problem { get { return (string)base.Problem; } set { base.Problem = (string)value; } } } } Tag: How to play an audio file?
