    - How to return the pointer of int32 in C# .NET? Hi, I am a bit shocked that C# got nothing to do with C/C++. Here is what I wanted to do; Int32 f_nSomeValue = 200; // Supposed to be 4 bytes long in length, right? MemoryStream f_MemoryStream = new MemoryStream(20); f_MemoryStream.Write(&f_nSomeValue, 0 , 4); The first param of the MemoryStream is expecting byte[ ]. I tried to cast it but the complier would not let me to continue. Does anyone know how do I convert the int32 so that it is can be used on the MemoryStrem.Write( )? Thanks for reading.

    - Save a System.Drawing.Color in the db Hi, I have a DataTable that has a Color type DataColumn. I use OleDbDataAdapter.Update(myTable) to update the db. Is there a place(an event?) where i can do a type conversion from Color to string (or int) so that the value can be saved in the db? What is the preferred way of saving/reading Color DataColumns in the db? The point is the call to OleDbDataAdapter.Update(myTable) appears to be atomic an offers no event to do such a conversion. Therefore, you end up with a string column in the db, and an incompatible Color DataColumn in your DataTable ! I'm caught with this. Thanks for any help! Tag: FrontPage Extensions Tag: 97572

    - Self populating collection Hi Has anyone encountered the following situation (I cant believe I am the first.) As part of a system I am designing I require a collection class that populates itself. So far I have a design along the following lines. public interface IFactory { IItem NewItem(); IItem[] NewItem(int count); } public interface IItem { void Load(OLEDBCommand Command); Implementers load internal values by executing command void Load(OLEDBDataReader DataReader);Implementers load internal values by reading current record. } public interface ISelfLoadingCollection { void Load(OLEDBCommand command , IFactory factory, bool loadAll); } public class SomeItemClass :IItem { ... Implementation of IItem and other class specific stuff. (You get the general idea) } public class SomeItemClassFactory:IFactory { ...Implementation of the IFactory stuff. IItem NewItem() { return new SomeItem(); } } public class SelfPopulatingCollection : DictionaryBase, ISelfLoadingCollection { ... Implements self loading collection stuff and exposes strongly typed dictionary of IItem's void Load(OLEDBCommand command , IFactory factory, bool loadAll); { Code here calls ExecuteReader on command, loops through rows calls newitem on the factory and passes the DataReader to the new IItem. The new IItem is then added to the dictionary. } } In the app I intend to create a new instance of the SelfPopulatingCollection, call the Load passing in the correct factory and command and watch it do its work. Why ? well I only want to write my collection management code the once and have all collections load the same way across my system (there are other reasons.) I am sort of happy with the design but it doesnâ??t feel entirely natural. The factory part seems inelegant (maybe the whole design is.) So I thought maybe someone had a better pattern for this. Who knows? rip it/me to shreds then ladies and gents. Regards Ben. Tag: FrontPage Extensions Tag: 97561

    - DBConcurrency Exception Handling hi, I am creating a dbconcurrencyexception in my program. Update fails with 0 rows affected message. Because I changed the data in DB from SQL server front-end after my grid fills with data. i followed the example in msdn. in the handler, after prompting the user, i read the record from the DB and merge it with the current dataset. And try to update db again. The result is the same exception. Because merge does not override the original version of the record in the grid. So what should i do to handle this exception?

    - Implementing an interface by relying on base class Hi, I'd like to do be able to implement an interface in a derived class by relying on the base class for some of the members. For example like this: Interface ITest Property prpA() As Integer Property prpB() As Integer End Interface Public MustInherit Class BaseClass Public Property prpA() As Integer Get Return 1 End Get Set(ByVal Value As Integer) End Set End Property End Class Public Class DerivedClass Inherits BaseClass Implements ITest Public Property prpB() As Integer Implements ITest.prpB Get Return 0 End Get Set(ByVal Value As Integer) End Set End Property End Class But the compiler doesn't recognise prpA as being present in DerivedClass. Can anyone tell me how I could get round this, and also why it should be that this is not allowed? Thanks, Gareth Tag: FrontPage Extensions Tag: 97554

    - Gridview, using Callbacks when Sorting and Paging For some reason when I enable the callback feature of the gridview I still get a page refresh, that is it seems like there is a postback that occurs, not a callback which is just supposed to update not the whole page, but a portion of the page. Strangely enough the URL below http://beta.asp.net/QUICKSTARTV20/aspnet/doc/ctrlref/data/gridview.aspx (VB GridView Paging and Sorting Callbacks example) has a callback example for gridview which explains that there should NOT be a page refresh, but it sure seems like the page refreshes (flickers) when I run the example. Also another example I found on the web on msdn http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvs05/html/GrdDetView.asp (Listing 4. Using Callbacks when Sorting and Paging section) states that... <snipp> Client-Side Sorting and Paging The GridView control provides you with the option of sorting and paging records without requiring a form-post back to the Web server. In other words, you can re-render the contents of a GridView when sorting and paging, without needing to re-render the entire page. You enable client paging and sorting by assigning the value true to the EnableSortingAndPagingCallback property. When this property has the value true, the GridView uses JavaScript to request an updated set of records from the Web server. <snipp> I tried the piece of code that was provided... <html> <head runat="server"> <title>Callback GridView</title> </head> <body> <form runat="server"> <%=DateTime.Now %> <asp:GridView DataSourceID="TitlesSource" EnableSortingAndPagingCallbacks="true" AllowPaging="true" AllowSorting="true" Runat="Server" /> <asp:SqlDataSource ID="TitlesSource" ConnectionString= "Server=localhost;Database=pubs;Trusted_Connection=true" SelectCommand="SELECT * FROM Titles" Runat="Server" /> </form> </body> </html> but even though sorting and paging callbacks are ENABLED, the TIME which is NOT supposed to be updated, still gets updated everytime I do a sort or change the page. Does anyone have any idea why this is happening? Am I misunderstanding the whole concept of callbacks? I made sure I am using the 2.0 framework and using ASP.NET 2.0, just because I installed Visual Studio 2005 on top of my existing Visual Studio 2003. This sucks...I hope someone can shed some light for me into this. Thanks for your time and help in advance. Best Regards, Tim :-) Tag: FrontPage Extensions Tag: 97550

    - FileSystemWatcher not firing events if Path is an empty string Dear All, In my C# application using .NET 1.1 I am trying to watch for file and directory events using FileSystemWatcher. Things are working as expected if I watch a specific directory. However I need to watch all folders on the local computer and I understood MSDN documentation that I can achieve it by setting FileSystemWatcher.Path to an empty string. I also set FileSystemWatcher.IncludeSubdirectories to true. However with this combination of properties FileSystemWatcher does not seem to fire any Created/Deleted/Renamed events on XP SP2. Am I doing something wrong? Thanks, - LR Tag: FrontPage Extensions Tag: 97521

    - Text Files, Encoding and NewLine character hi, I'm creating a component to read text files. I'm using TextReader with Encoding Text component, because there are several different types of text files and the encoding component translates the bytes from this file to the correct characters. To which one of this text file's types almost all the time '\r\n' is the new line character. But sometimes it could not be, that's why I'm using NewLine property to know exactly who the next line characters are in which case. At that point all work's fine with TextWrite, but hell knows why TextReader doesn't have a NewLine property. Is there any way to identify the NewLine character of a determinate Encode system? or just stop using the NewLine and work only with '\r\n'? Another question, TextReader copies all file from the harddisk as soon as it is initiated, or it copies part of the file when I'm using Read();? Thank you, Roby Eisenbraun Martins Tag: FrontPage Extensions Tag: 97495

    - A challenge to all MVP's.......GET A J.O.B. for once in your life You guys who hang around here are some of the sorriest and most incompetent programmers( if you can even be called that) ever!!! The only thing you know are reference books and theory that's been proven wrong in the real world You sit in front of your computer answering the SAME nickel and dime questions day after day, week after week, year after year so you can't possibly have any real experience in making an actual program and all you do is give BAD advice to those seeking it here. As far as I am concerned, Microsoft should end the MVP program as all that it fosters is wanna be programmers who only give bad advice and never DO as they ADVISE. You have essentially ZERO experience in coding .NET to begin with. DEAR MICROSOFT: Kill off the MVP program. It only fosters people who strive for publicity in trying to get a programming job as opposed to being actually able to do the job. The MVP's only make programmers and the software industry look bad as a whole as these people are supposed to be MOST VALUEABLE....when in they in fact are the MOST WORTHLESS programmers ever, especially when they actually do get a job they only sit around with theory, and all that nonsense of architecture and best practices only to not even deliver the project to begin with. Why not put all that theory and knowledge to the test and actually see if it really works? Ha ha ha..like you can even do that? All these people do is get silly certification and they STILL CANNOT GET A JOB!!! Much less actually do the job.....Imagine that!!! It's no wonder companies go off shore, as the quality of software sucks anyway, so why pay extra in the US when it's going to be late, buggy and not what the customer wanted anyway. MESSAGE TO MVP's: WAKE UP!!! START DOING SOME REAL WORK or someone will make sure the world knows how incompetent you MVP's are and if you think you will have a hard time now flashing your MVP and Certification letters around, wait till they know the real truth about you and will think twice about even mentioning you have a certification or MVP status......and no talking in front of user groups don't count as most those groups are also like you, unemployed, can't get the job done right.

    - Parameter Methods Performance (val,ref,out) Hi, I would like to know which one of the following parameter types is faster. I think is ref because sending a pointer to a class seems to be much more faster then copy all the class at once in the method call. But when I was having classes about C# programming in Microsoft Official Course, my teacher told me that in .NET val is faster, that's why it is the default parameter type. But he couldn't explain why. Any ideas? Thank you. Roby Eisenbraun Martins Tag: FrontPage Extensions Tag: 97441

    - Checking for implementation of an interface I have an application that accepts plugins. It allows the user to choose which plugins they want to run from a list of available plugins. My problem is that I need to build that list of plugins by checking the assemblies in the plugins folder to see if they implement the plugin interface. If I load each assembly and check it, then I have all those assemblies in memory until the application gets shutdown, even though the user may only want to use a few of them. My idea was to load them all into a separate appdomain to check them and build my list, and then unload that domain. Then I could just load the plugins that the user chooses. My problem is that I don't know how to check the assembly to see if it implements the plugin interface once its loaded into the separate appdomain. Can anyone point me to an article on this, or some sample code? Thanks! Tag: FrontPage Extensions Tag: 97414

I have tried: Dim env As EnvDTE80.DTE2 = CType(Microsoft.VisualBasic.Interaction.CreateObject("VisualStudio.DTE.8.0", ""), EnvDTE80.DTE2) but that tells me it cannot create the ActiveX object. I then tried: Dim env As EnvDTE.DTE = CType(Microsoft.VisualBasic.Interaction.CreateObject("VisualStudio.DTE.7.1", ""), EnvDTE.DTE) and that creates the object, so when I do this: ENV.Solution.ADDFromTemplate("C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\VBExpress\ProjectTemplatesCache\1033\WinFXApplication.zip\WinFXApplication.vbproj", "e:\mytests", "myproject.vbproj") I get the message "The file blah blah is not a valid project file.

That is, the class is registered for COM interop, and may be instantiated by VBS code, etc. We are using the inherent .NET Framework licensing classes. We've used the LicenseProviderAttribute to specify a LicenseProvider descendent. The LicenseProvider descendent's GetLicense() method checks the LicenseContext for LicenseUsageMode.Runtime or LicenseUsageMode.DesignTime. This works great when the class is being instantiated by a .NET application. We run into a problem when the class is instantiated via COM interop from, say, a VBS script. When started this way, the GetLicense() method LicenseContext argument is _always_ LicenseUsageMode.DesignTime. This upsets the licensing model we want to use. Is this working as designed? I had hoped a class instantiated via COM interop would be seen to be working in LicenseUsageMode.Runtime mode, not LicenseUsageMode.DesignTime. Thanks in advance, Grant Tag: FrontPage Extensions Tag: 97411

    - Call was rejected by callee Hi, I am having a problem with a vb.net mappoint application. Currently in my application I have pushpins that move according to GPS locations that are constantly being updated. Everything seems to work fine but when I start using the toolbar functions in the mappoint object while tracking/updating points I always get this following error: An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in TrackBerryMapPoint.exe Additional information: Call was rejected by callee. For example, if i use the location search bar while I'm tracking, the find dialog box pops up and then everything crashes. I'm using a timer for the updates of the tracking points and I think that might cause the exception. If anyone has an suggestions I'd appreciate it very much.

    - Subform ia unexpectedly closing parent form problem Hi, I'm using the .NET environment, writing in C#. I have a windows form application which is causing me a headache. I have a main form and also a subform, when I close the subform, the main form also closes, which obviously terminates the application. I've checked my dialog result from the subform and it's all looking fine. The form was imported from another project with no apparent issues, I'm not sure if this has any thing to do with it? Many thanks for your input. Stuart Tag: FrontPage Extensions Tag: 97397

    - Some services stop automatically if they have no work to do, for e I got a Server Class in an executable and I would like to change this in a windows service. The code from the main function of the executable is the following: LoadReportingServer server = new LoadReportingServer (); server->Start (); Console::WriteLine (S"Press ENTER to stop the server..."); Console::ReadLine (); server->Stop (); server = 0; I tried to turn this into a service following two tutorials, and it compiles fine. Whenever I start the Service in the Service Manager, I get the Message that my service started and stopped again. Attempt 1: using System; using System.Collections; using System.ComponentModel; using System.Data; using System.Diagnostics; using System.ServiceProcess; namespace SoftwareLoadBalancing { public class LoadReportingService : System.ServiceProcess.ServiceBase { /// <summary> /// Required designer variable. /// </summary> private System.ComponentModel.Container components = null; private LoadReportingServer server; public LoadReportingService() { // This call is required by the Windows.Forms Component Designer. InitializeComponent(); // TODO: Add any initialization after the InitComponent call } // The main entry point for the process static void Main() { System.ServiceProcess.ServiceBase[] ServicesToRun; // More than one user Service may run within the same process. To add // another service to this process, change the following line to // create a second service object. For example, // // ServicesToRun = new System.ServiceProcess.ServiceBase[] {new Service1(), new MySecondUserService()}; // ServicesToRun = new System.ServiceProcess.ServiceBase[] { new LoadReportingService() }; System.ServiceProcess.ServiceBase.Run(ServicesToRun); } /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> private void InitializeComponent() { components = new System.ComponentModel.Container(); this.ServiceName = "LoadReportingService"; } /// <summary> /// Clean up any resources being used. /// </summary> protected override void Dispose( bool disposing ) { if( disposing ) { if (components != null) { components.Dispose(); } } base.Dispose( disposing ); } /// <summary> /// Set things in motion so your service can do its work. /// </summary> protected override void OnStart(string[] args) { // TODO: Add code here to start your service. server = new LoadReportingServer(); server.start(); } /// <summary> /// Stop this service. /// </summary> protected override void OnStop() { // TODO: Add code here to perform any tear-down necessary to stop your service. server.Stop (); server = null; } } } This does not do anything but displaying the message that it started and stopped again. Attempt 2: using System; using System.Collections; using System.ComponentModel; using System.Data; using System.Diagnostics; using System.ServiceProcess; using System.Threading; namespace SoftwareLoadBalancing { public class LoadReportingService : System.ServiceProcess.ServiceBase { /// <summary> /// Required designer variable. /// </summary> private System.ComponentModel.Container components = null; private ThreadStart threadDelegate; private LoadReportingServer server; public LoadReportingService() { // This call is required by the Windows.Forms Component Designer.

    - "scrolling buttons" I would like to make some kind of buttons that can be used to scroll other things. Actually it would like it to be exactly as in Lightwave's Envelope Editor - when you push the button, the mouse pointer should disappear and you should be able to scroll something with moving your mouse up/down and left/right. Perphaps hiding mouse wouldn't be that hard [or would it?], but I wonder about "scrolling" itself - I generally use MouseMove event, and in this case the pointer would quickly leave the button's area and i would get no event to handle... What's the best way to deal with that?

What OS are you running? Win 2000 Pro comes with IIS 5.0, Win XP is IIS 5.1,
and all 2003 OS's are 6.0. In order to create ASP.NET applications you have
to have access to IIS. In VS .NET 2005 you won't need it anymore because it
has built in hosting capabilities for development.
