    - Problems with enum Documentation (NDoc Problem?) No "Description" in resulting HTML File using NDOC (Version 1.2.1303.41457). From the Framework side I think I am doing everything correctly, because the resulting XML has the coments. Is this a known NDoc problem? Is there a NDoc newsgroup?

    - Uninstalling a NT Service programmatically Hi NG, I'm writing a management tool for our software, that among other should be able to install and uninstall some of our NT services. The problem is that when I uninstall the services (using ManagedInstallerClass.InstallHelper with the "/u" parameter) the services are uninstalled, but they are still running until I close my management application. This is a problem since I want to remove the service assemblies as a part of the uninstallation. I read the Knowledge Base-article 287516 (http://support.microsoft.com/default.aspx?scid=kb;en-us;287516), which seems to be addressing my problem. It claims that all handles to the services needs to be closed before the service can be uninstalled. Thats fair enough, but eventhough all my ServiceControllers are Close()'d and Dispose()'d the problem persists. Is there a way to release all handles to a service allowing it to be uninstalled at once? Or is there another way to do this? Thanks for your time, Ricky Tag: C# Training Videos Tag: 65037

    - Enumerating windows from an NT service Hi all, The service I have written can not enumerate the current user's desktop windows when running as a service. I read where one solution to this is to install the service with "SystemAccount" rights and "Allow service to interact with desktop" but I know it leaves the system vulnerable to maliciousness. Is there a way to programmatically enumerate through the current desktop windows when running as a service? Also, How I can know the name of the user when he logged?

    - .Net Framework SDK Licence Agreement and OpenSource I am looking to start an Open Source project using C# but the requirements of the project require that the project must be written in a language that has freely available compilers. I am correct in think that the .Net Framework SDK is a free download from Microsoft and could be used for such an Open Source project with these requirements? I have tried finding an End User License agreement for the SDK without success. Can someone provide me with a URL to such an agreement so that I can provide this to the administrators of the Open Source project to satisfy their concerns.

    - activex textbox vs windows forms textbox I'm porting an MS Access application to a .NET windows forms application. For several forms I need to use textboxes which support input masks and whose border color I can change, neither of which seem native to .NET. Is the addition of activex controls my only solution. So far, I've only found Microsoft's masked edit control (V6) which supports the input mask, but doesn't give me any control over the border color. Does anyone know if there are any better activex textboxes out there which fit the bill, or if there is a native dotnet solution that I'm missing and I could implement?

So, my software can prevent process of copying(installing) of somefiles. My question is how can I know that process (where is it copy from?, What is its name? ...) I attempted to use FileSystemWatcher() but I couldnot know where files come from. What I need is prevent copying from somefiles (they come from Floppies, CDROM) so I must know where those files come from. Please help me as soon as possible. It is urgent for me. Thank you.

    - Is there an upward limit to the System.Timers.Timer.Interval value? I am using a timer in my Windows service previously discussed in my previous post to send warning e-mails to users who's account activity idle for a given number of days. Currently I have it set for 30 days, which I multiply by a base value for one day in milliseconds. The value that is currently being used is: 2592000000, which when divided by 24 * (60^2) * 1000 comes out to 30 days as it should. Can the timer not be used in this way? If it can't how does one accomplish this type of timing? Carlo Tag: C# Training Videos Tag: 64996

    - Process.Exited doesn't throw? I am writing a Windows Service that monitors a running instance of another (third-party) application by using the Process component. I set it up to listen for the Process.Exited event, but that event never seems to be raised. I tested further, using a .dll that runs in NUnit (just a handy place to test little hypotheses when I run into questions like this) and it still wouldn't recognize the closure, cancelling, killing or otherwise ending an application. I tried running on a different machine, and no dice. Is this a known issue? I'm responding to this event just as I would any other event. Is there something I missed? I'd rather not do a timer loop that constantly checks the state of the Process. Thanks for your help. -Marc Tag: C# Training Videos Tag: 64990

    - reading machine.config file I have a problem that involves many technologies - if anyone thinks there's a better group to post this to, don't yell and scream, just let me know. OK, our company is developing apps with VB.Net (using Remoting) and Crystal Reports. To solve the problem of creating multi-language reports, I wrote a UFL (User Function List) to do all the translating. I won't get into specifics, but this UFL is just an ActiveX dll written in VB6 (Crystal doesn't support writing them in .NET) that reads the translations from a SQL Server database. In addition, we have many apps and they use about 10 different databases. Since we're using remoting, the data access objects reside on our web server. All the info this data access object needs to connect to the databases is stored in the machine.config file of our web server (I know the machine.config is probably not the best .config file to store this info in - but that's where my boss says it has to be!) Finally, my problem. The Crystal reports are also running on the web server and I would like my ActiveX dll to be able to read the machine.config file for the SQL Server logon info (for it to get its translations) just like my .Net apps do. Obviously, I can't use the framework methods since the dll is written in VB6. What's the best way to find the location of the latest framework verion's machine.config file. I know I could write some hokey folder traversal method to try and find what version folder to look in. I may also be able to look in the registry, but I'm just looking for a cleaner solution. In conclusion, I'm looking for an easy and clean way to find the location of the latest version of the machine.config file without using the framework methods. Thanks in advance!

    - QueryString and Web Forms Hello, I have a few web forms: 1) Shows a list of items with item ids 2) Shows details specific to an item and the sub-items of this item. What is the best way to pass the item id of the selected item from the 1st page to the 2nd? If I pass the value in the query string from the first 1st form to the 2nd, the 2nd form's URL will always contain that it in it since ASP.NET uses POST method and not a get method. So if on the 2nd form there is a way to pick a different item from a drop-down list, the URL will still contain the id of the orginally selected item, while the details will be shown for the item that was subsequently selected from the drop-down. This does not look right. Should I use the Session() to pass the item id of the selected item from the 1st to 2nd page instead of the QueryString method?

    - problem with shared assembly reference in VS solution I'm having a problem with shared assemblies > 2^16 bytes in size. My assembly is in a solution along with a console app that references the assembly. The app is set up to reference the assembly (the reference path is pointed to the assemblies output directory). When I do a build, the assembly is failing to build because the .dll is loaded. I'm getting the following output from the build: The file 'Test_Library.dll' cannot be copied to the run directory. The process cannot access the file because it is being used by another process. Could not copy temporary files to the output directory. I've created a few other shared assemblies with no problems. This is the first time I've seen this exact problem and in trying to run it down I've discovered that if the .dll's size is < 65536 bytes (as all my other ones are), this doesn't happen. It looks like VS is loading the .dll when I add the reference for the console app. If I delete the console app's reference to the assembly, I am able to build the library. I hope one of you has run across this before. thanks for any help, Tim Tag: C# Training Videos Tag: 64956

    - OleDbCommand parameter datatype marshalling issue with MS Access Hi, When I create a table in MS access 2000 with SR3 using a standard SQL Create command The BOOL (YesNo) columns are NOT checkboxes, they are ints. When I create a table using the designer the BOOL YESNO fields are checkboxes. Smells like a BUG. When I call OleDbCommand with a BOOL in the parameters to update, I get "Syntax in UPDATE command" beecause this datatype is not matching because of this bug. The command runs fine when copy and pasted to the query window in MS Access directly. Smells like an Access and OleDb class bug Tag: C# Training Videos Tag: 64944

    - Getting Cokkies values using FORMS authentication Hello, Iâ??m developing in ASP.NET using â??Formsâ?? authentification: Iâ??m asking â??LOGINâ??, â??PASSWORDâ?? and â??KEYâ?? Web.config: <authentication mode="Forms"><forms name=".SOMETHING" loginUrl="login.aspx" protection="All" timeout="5" path="/"></forms></authentication> As you like read, I am using the attribute protection="All" (encrypting the cookie). Everything is running very well, â??BUT...â??, I have the following doubt: Is possible that I can apply something like: vAux = HttpContext.Current.Server.UrlEncode(â??LOGINâ??) LOGIN = HttpContext.Current.Request.Cookies.Get(vAux) vAux = HttpContext.Current.Server.UrlEncode(â??PASSWORDâ??) PASSWORD = HttpContext.Current.Request.Cookies.Get(vAux) vAux = HttpContext.Current.Server.UrlEncode(â??PASSWORDâ??) KEY = HttpContext.Current.Request.Cookies.Get(vAux) for getting DESENCRYPTED values?? (I know that the code above is not correct) I need that values for using its with others functions. Could someone help me? Thanks in advance!, l-touched Tag: C# Training Videos Tag: 64940

    - sql connection in windows service doesn't work! Hi all, Ive made a Windows Service that basically makes connections to a Sql database, when it connects it runs a stored procedure. Below is the static procedure. This procedure is in the Windows Service and the procedure runs and an Eventlog is successfully written with no exceptions. If I take this simple code and put it in a test console app with the same connection, stored procedure and email address it runs no problem. The problem I have is that I get no errors so im thinking its some kind of Threading issue? I just dont understand why this code with the same parameters can work fine in a stand alone console app rather than incorporated into a windows service. And still the windows service doesn't give me any error, and the stored procedure doesn't run! I have verified that the stored procedure is there and works! static void runme(string connection, string remove, string emailaddresss) { try { SqlConnection con = new SqlConnection(connection); SqlCommand com = new SqlCommand(remove); com.CommandType= CommandType.StoredProcedure; SqlParameter myParm = new SqlParameter("@email",SqlDbType.NVarChar,25); myParm.Value = emailaddress; com.Parameters.Add(myParm); con.Open(); com.Connection = con; com.ExecuteNonQuery(); con.Close(); com = null; con = null; EventLog.WriteEntry("MMS", " " + connection + " " + remove + " " +emailaddress); } catch(System.Exception e) { EventLog.WriteEntry("Service", "Exception is as follows: " ex.Message); } } Thanks very much for your help. phil Tag: C# Training Videos Tag: 64938

    - Directory.GetFiles throw an exception Hi, The following statement throws an exception when the search pattern returns no files: string[] files = Directory.GetFiles(directory,"*pl*.txt"); Is there any way to find out whether there isn't a match so that I don't have to wrap the above code up in a try- catch block?

    - SSL Server Certificates - TrustFailure Hi I am trying to connect to a remote server using the System.Net.HttpWebRequest class and an https: address, but I am getting a WebException with a 'TrustFailure' status. I think the problem occurs because the server name doesn't match that on the server certificate (it is a test server, but it has the company's main certificate installed). If I try to connect using IE, it warns me about this, but still allows me to connect. Does anyone know if I can 'turn off' the server certificate validation on the HttpWebRequest so that I can still connect to this machine? Any ideas or suggestions will be much appreciated.

    - Custom Control with custom Control_Collection I am creating a new custom Control which derived from Control. I also wish, in my derived control for it to use a derived/custom Control_Collection property. I need this because I want to intercept calls to Controls.Add(someothercontrol) and Controls.Remove(someothercontrol). Overriding the OnControlAdded and OnControlRemoved methods isn't an option because they occur too late for what I need to do, specifically those methods are called -after- a Control has already been added or removed from the collection. I can certainly derive my own Control.ControlCollection class but how do I get an instance of -my- derived Control.ControlCollection "attached" to my derived Control class? The Controls property in Control only has a -get- accessor and none of Control's constructors allow one to construct a derived class with a Control.ControlCollection parameter. I -think- I should override the protected virtual ControlCollection CreateControlsInstance() method and inside of that overriden method create/return an instance of my derived Control_Collection class. Is this right? Oz Tag: C# Training Videos Tag: 64925

    - Performance of StringBuilder string strContent = String.Empty; foreach (string strLine in Content) // Content is a ArrayList which contains a large amount of strings strContent += strLine; StringBuilder aStrBuilder = new StringBuilder(); foreach (string strLine in aStrBuilder) aStrBuilder.Append(strLine); strContent = aStrBuilder.ToString(); Which method is faster? Is there any article which talks about the performance of StringBuilder in deep? Thanks. Tag: C# Training Videos Tag: 64921

    - COM interfaces and making different overrides for methods Assume there is a COM server on the system which exposes an object with the interface below. GetBuffer() will fill a buffer of several different types... and its a pain to have to allocate an unmanaged buffer and marshal each one manually. Isn't there a way to indicate overrides for methods? I tried just adding the method definitions and setting a DispId, but the DispId has no effect with ComImport, and the order of methods confuses COM/.NET (.NET sees that as three different distinct methods). The only solution I've found was to redefine the entire interface and make custom method definitions for each interface... but the interface is actually *MUCH* larger than the one below... plus its a pain to have two different names for each interface override. Any input would be appreciated. [ComImport, Guid("9473974-some-guid-124359")] [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)] public interface ITestInterface { [DispId(1)] void GetBuffer( [Out] out Guid guid); [DispId(1)] void GetBuffer( [Out] out CustomStructure data); [DispId(1)] void GetBuffer( [In, Out] IntPtr buffer); } Tag: C# Training Videos Tag: 64917

    - Non-remoting proxies Is there a proper way to use the proxy classes to set up a proxy for a local object? The code below is what I have tried. This seems at first to work, as the object I create is a transparent proxy, however, my overridden Invoke() is never called after the initial construction I tried removing the attribute, and creating an instance of the proxy directly. This worked, however, at certain points in code execution the object returned would no longer be a transparent proxy, and instead the actual object itself. This at first seemed to only happen when passing the object to a method via the "this" keyword inside of the object. However, more testing showed that this was happening at other times as well Is there a way to intercept all calls to a class? This is neccassary in my project to insure that an object written by any author cannot be used after it is no longer valid, since we are unable to delete objects explicitly.
