    - Events over LAN Hi, I'm developing a client / Server application that mainly comunicates via a shared database and OPC server via DCOM. But I need to fire events when a update is performed on the client or server. If on of the clients is updating it should send an event to the server, then the server would send events to all clients. The events don't need to contain data. What is the best way to do this when IIS and webservices are not an option ? Tanks Totto Tag: how to solve prblem Tag: 89567

    - TreeView Question I am deriving my own TreeView control from the 1.0 Framework TreeView. I have overriden the OnAfterSelect method and want to respond to selection of a node. The issue I am having is that if the user selects a node and then clicks the node again, no OnAfterSelect event is triggered. I figure this is the way it is supposed to work but would like to work around this. Has anybody had this issue and found a way to work around it? I thought I could monitor OnMouseUp events and see if the left mouse button is clicked on the selected node and then call OnAfterSelect from with in OnMouseUp. This creates a new issue of when you actually do select another node, now OnAfterSelect gets called twice (once for the select and once for the mouse up event). Oh and in case your wondering, I'm pretty sure the OnAfterSelect event is fired before the OnMouseUp event. A snipet of my code is shown below: protected override void OnAfterSelect(TreeViewEventArgs tvea) { base.OnAfterSelect(tvea); ... do really cool stuff when node is selected! ... } protected override void OnMouseUp(MouseEventArgs mea) { base.OnMouseUp(mea); if (mea.Button == MouseButtons.Left) { TreeNode node = GetNodeAt(mea.X, mea.Y); if (node == this.SelectedNode) { OnAfterSelect(new TreeViewEventArgs(this.SelectedNode)); } } } Tag: how to solve prblem Tag: 89563

    - Usage of .net class lib in a windows service Hi, I'm developing a windows service with c#. Now I'm trying to use a .net class library (dll) to include. For this I added the dll to my references. But unfortunately if i run the service i got always this error: File or assembly name "myClassLibrary", or one of its dependencies, was not found. Does someone knows where i have to place my dll that it could be found by my windows service. I already tryied to place it in the System32 folder and also in the same folder as the windows service is. But without any success. :( Thank you for your help!

    - Apparent issues while using System.DateTime In my application I store all transaction dates in UTC in the database. At the time of displaying the transactions in the UI I convert the date to local date time and then display the same to the user. I do the following: string LocalDtTimeString = Convert.ToString(DtClass.ConvertToLocalDateTime(System.DateTime.Parse(strDate))); where strDate is the string representation of the date fetched from the database. and the DtClass method implementation is: public class DtClass { : : public static DateTime ConvertToLocalDateTime(DateTime UTCDateTime) { return UTCDateTime.ToLocalTime(); } : : } Scenario is: My UI is in the context of PST. I perform a transaction at 4:30 PM (PST). Database stores the date as next day morning 12:30 AM (UTC). Now I changed the Time Zone of my machine from PST (GMT - 8) to EST (GMT - 5). I run my UI and see that it shows the transaction time as 10:30 PM (EST) instead of showing it as 7:30 PM (EST). This is happening on a test machine. When I wrote this code and tested it on the development machine, it was correctly converting times and giving respective local times. Is there anything that I need to change in the code that will make it work consistently on all machines? I looked around regarding this issue on the internet and read some material, which talks about behavior differences based on the culture notably with DateTime.Parse and DateTime.ToString. I don't understand why it subtracts 2 hours instead of 5... I would really appreciate your help... Thank you... -Avinash Tag: how to solve prblem Tag: 89550

    - .NET Framework v1.1 SP1 locks PC up... I ran the Windows Update in which it offered v1.1 SP1 of the framework. I installed it and rebooted as required. When I came back into my pc, the desktop appears frozen (I can't even bring up Task Manager). The bizarre part of this problem, if I wait 15-20 minutes my PC will come back to life and work as "normal". I've done a google search and found several similar reported problems after installing v1.1 SP1. Anyone hear had or having this same problem?? What is very strange is that v1.1.

    - Connected Status on Sockets I have created a socket application in C++.NET that connects in non-blocking mode. All my previous apps of this kind have used blocking mode at the connection, but in this case I did not want the app to wait if the server was not available. In the course of doing this, I discovered after several hours of frustration that the Connected property of the socket is not set in non-blocking mode even after the connection is completed. Maybe this is documented someplace, but I could not find it. Is this behavior to be expected or have I got an error someplace else? I got around this by using Poll instead to check for the connect status, but I would still like to know why Connected is not working. Thanks, Bill Tag: how to solve prblem Tag: 89536

I can't seem to find anything on google either. Anyone remember this or have a link to a KB article? I think it had something to do with the aspnet_client files directory and where it was stored.

    - Errors from Socket Functions I am using C++.NET to build an application using sockets. I am connecting to multiple servers, some of which may not always be available. I am setting blocking off before connecting and using the poll command to detect when the connection is complete. This works fine, but if there is an error, like connection refused, I can't get the speicfic error. In the docs it says to use GetLastWin32Error, but that always returns zero. In my past experience with the function, I found that I had to use the DLLImport function to activate the specifc API call. I feel that I must have to do something similar in this case, but I don't know how to compose the DLLImprt to provide this functionaltiy to the socket functions. Please let me know if I am going down the right road, and what I need to do to make this work. Thanks, Bill Tag: how to solve prblem Tag: 89527

    - SP2 & "The Publisher could not be verified. Are you sure you want to run this software?" Hello. Our company has created a .Net application which the user starts by executing via a URL (i.e., http://someserver/application.exe). On some machines running Windows XP SP2, the user will see a dialog containing the message "The Publisher could not be verified. Are you sure you want to run this software." This does not happen on most machines running SP2, but it does occur on a couple. And yet, the Security settings on the machines where it does occur seems to be the same as on the machines where it doesn't happen. Can anyone tell me how to turn this off? Thanks.

    - hOW TO DO THAT IN .NET... FRAMEWORK? I have wave files being recorded for interactive voice enabled application. Currently I have more than 1000 wave files implemented in the application. Since I have recorded using regular desktop PC the quality of the sound is not good. Also the volume levels in each of the wave files are different. So what is happening is when I play more than one file at time, end user will hear some of the wave file in one pitch, some of them with different volume level making it an unpleasant experience for the end user. Is there any way using .Net application I can redit these wave file to bring atleast volume level of these files to the same. Do I have understood the file system where exactly the volume level is stored in the wave file? Your reply is highly appreciated. Douz Tag: how to solve prblem Tag: 89520

    - MarshalAsAttribute() Good Day and Happy New Year to all of you!

    - Bug in reflection? Is there a bug in reflection as follows?: If I have a method in a class [method:Obsolete] public ReturnType RandomMethod() { // ... } and using reflection I get the MethodInfo for this method then call MethodInfo.ReturnTypeCustomAttributes.GetCustomAttributes(false) to get the custom attribute object list for the *return* type, the returned array contains the *method* custom attribute object ObsoleteAttribute, whereas it should actually be an empty array. If I modify the method as follows (random example for demonstration) [method:Obsolete] [return:XmlIgnore] public ReturnType RandomMethod() { // ... } then I correctly get the return type custom attribute array consisting of one object, namely the XmlIgnoreAttribute.

Is there a "better" way of doing this? Secondly, I know that the code below for Validate() , requiredProperties etc. will never work - you can't put a reference to nothing into a collection. How could I effect this - or similar functionality? What I really want to be able to do is to put a bunch of pointers into an array and check in Validate() whether they point to an instantiated object... (The idea here being that I can abstract the logic for validating common objects like these into a base class.)

    - strange form behaviour... I am busy with a program for my pocket pc. but since it is still compact famework, I'll post this here too, because I'm very much in need for some help with this: I have one form which is my main form and has 4 option buttons and two regular buttons, one for saving and the other for canceling the program. When the user select an option button, a new form is opened and he can fill in some fields by using a context menu (standard answers). When he is finished, tapping on the save button, the form is hidden and the user is returned to the main form, where an image is drawn that the form is filled in and done. After that the form is disposed After the second button he chooses the third option, but the form of option 2 is show, by either tapping on save or cancel, the form is hidden/closed, and the form that should have been displayed is opened. When clicking on the save or cancel button, an exception error occurs, a disposed exception. The same thing happens when the second option is skipped and he goes first to the third option and then the fourth. Instead of showing the fourth, the third is shown and after closing it, a disposed exception appears. Basicly this is what is done: a.. create instance of new form b.. set the textboxes with text from dataset table c.. show the form with showdialog d.. dispose of the form when it returns Nothing fancy, but with that strange error.

    - general question regarding when to abstract vs. interface This is just a thought I wanted to put out there to get some opinions... I've been programming for a number of years, but until a couple of years ago, always with VB6, so everything I did to "fake" inheritance was done with encapsulation. About two years ago, I began working with .NET and C#. This question has bothered me for a while, but never enough to cause any great concern in my work. I just started designing a new project, and the question has popped up again.... Can you think of a time where you would intentionally choose to use an interface instead of an abstract, other than as a workaround for the lack multiple inheritance support? Iss there any general rule or rule of thumb or best practice that has been formulated that dictates when to use interfaces vs. when to use abstract classes. Thanks for any comments.

    - Proper place for custom CONFIG file Hello, We have a set of applications and assemblies that belong to one project. Some of the configuration settings are supposed to be shared between various assemblies on the same machine. After long discussions we finally decided that the best alternative for us is to create a custom configuration file <OutProject>.config and place it in a common directory. Then we can write our own configuration parser that will return NameValueCollection settings. There seems to be two good places to install such file: <Windows>\Microsoft.NET\Framework\<CurrentVersion> and <Windows>\Microsoft.NET\Framework\<CurrentVersion>\CONFIG. Both of them contain several configuration files. My first impression was that the latter one is the best (since it's called CONFIG), however it contains only system specific configurations files like machine.config. All application-based config files are located one level up, inside <Windows>\Microsoft.NET\Framework\<CurrentVersion>. Do you know what is the best practice?

    - Exporting registry key to a reg file? I've had a look around and AFAICT, the Microsoft.Win32.RegistryKey class doesn't have any members that write the registry to a reg file. So, as I see it, the options are: 1. Use Microsoft.Win32.RegistryKey to parse each value and write each to a reg file manually. This is a bit of a pain as I have to write all the code to keep the syntax of the resultant reg file correct. 2. Shell out and use regedit /e to export the file. Not ideal because when I do this, I believe that a separate thread is used, so my app carries on working whilst the registry is still being exported (noticeable for large exports). OK, I could monitor all this, but again, this seems like really hard work for such a simple job! 3. Use "advapi32.dll". This is my preferred option (assuming I'm right about point 1). However, I'm getting errors when running the code: [DllImport("advapi32.dll", EntryPoint="RegSaveKey")] public static extern int RegSaveKey(IntPtr hKey, string lpFile, int lpSecurityAttributes); IntPtr hKey; IntPtr hHkcu = new IntPtr((int)RegistryHive.CurrentUser); int ret = Win32.RegOpenKey(hHkcu, registrykey, out hKey); if(ret == Win32.SUCCESS) { Console.WriteLine("Return code: " + RegSaveKey(hHkcu, @"C:\regbackup.reg", 0).ToString()); } This compiles fine, and it appears to be trying to do what it's supposed to do. E.g. if I ensure that the file already exists, I get return code (from RegOpenKey) 183, which is what the documentation to RegSaveKey says I should get (file already exists, roughly). So, if I then make sure that the file doesn't exist, instead of getting return code 0, I get 1314, which seems to be a permission problem? However, I am an administrator. If I do the same from the command prompt using regedit, it exports fine. Any idea? Cheers Mark Tag: how to solve prblem Tag: 89429

    - SSL Hello, I use SSL in my mail application that is POP3/SSL. I download POP3 protocol library using standard socket. The library use Socket as an communication channel. For SSL, I use Mentalis implementation. However, Mentalis's SecureSocket is not inherited from Socket. So, I cannot use with POP3 library. How can I solve this problem? Must I modify POP3 library to use with Mentalis's? Thanks, Theewara Tag: how to solve prblem Tag: 89421

    - Unable to reuse remoting port I am registering an object for remote access in the constructor of a Windows Service using the following code: BinaryServerFormatterSinkProvider provider = new BinaryServerFormatterSinkProvider(); provider.TypeFilterLevel = System.Runtime.Serialization.Formatters.TypeFilterLevel.Full; IDictionary props = new Hashtable(); props["port"] = Convert.ToInt32(System.Configuration.ConfigurationSettings.AppSettings["Listen On Port"]); TcpChannel chan = new TcpChannel(props, null, provider); ChannelServices.RegisterChannel(chan); RemotingConfiguration.RegisterWellKnownServiceType(typeof(MyObject), "MyObject", WellKnownObjectMode.SingleCall); This seems to work just fine until I attempt to restart the service. If client applications have accessed the remote object and I attempt to restart the service, the service stops successfully, but I receive the following error when it's trying to start up again: "Only one usage of each socket address (protocol/network address/port) is normally permitted." I have to wait a good 5 minutes or so before it will let me use that port again. Is there some way in dotnet to force the port to be released so I can immediatly reuse it?

    - Providing IServiceProvider.QueryService to third party AX controls... I need to use a third party database Activex control that uses the IServiceProvider (aka IOleServiceProvider) interface to get an instance of the application API object. It uses this API object to get an OleDb connection string so that it can interact with a database. What is the best way to hook into the IServiceProvider.QueryService OLE mechanism in .net? As far as I understand, when the third party control receives an IOleClientSite instance via the IOleObject.SetClientSite method, it casts it to IServiceProvider and if not null, asks for the API object via the QueryService method. I have successfully cast the control to an IOleObject and passed my own instance of IOleClientSite (which also implements IServiceProvider), but none of the methods are being called. ((IOleObject) thirdPartyControl1.GetOcx()).SetClientSite(new MyTestClientSite()); For all I know, a different IOleClientSite is being given shortly after mine, or perhaps it's just a problem with the sequence of events. I really have no idea why it's not working. I also tried to use reflection to manually call Control.ActiveXInstance.SetClientSite(), but it kept complaining that my custom IOleClientSite implementation couldn't be cast correctly. This probably makes sense since it is expecting a UnsafeNativeMethods.IOleClientSite but actaully getting a WindowsApplication1.IOleClientSite (even though mine has ComImport and the same Guid).

As it says in the KB: "To work around this behavior, use the Timer component
that the System.Timers namespace provides." Do not use the
Windows.Forms.Timer class.
