    - managed extensions I'm having a problem compiling a managed extensions project that has one set of functions that is supposed to be unmanaged. I've found out how to set the properties of a single file, in which way I can set the /clr option on a file level, which is good. But when I add the unmanaged code as a .c file, I get Words fatal error C1190: managed targeted code requires '#using <mscorlib.dll>' and '/clr' option only if the /clr option for the file is set to true. But if I add them as a .cpp file, I get that same error if the /clr option is set to false. Could I not add them as a .cpp file with /clr off? Also I get the linker warning nochkclr.obj : warning LNK4099: PDB 'libc.pdb' was not found with 'C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\lib\nochkclr.obj' or at '...\libc.pdb'; linking object as if no debug info What's the resolution for this?

    - InputBox dialog In Borland's VCL there was an InputBox dialog, and also a slight variant called an InputQuery dialog, which asked the user to input information. I do not see an equivalent for this in the .NET framework. Does one exist in the .NET framework ? In the Systems.Windows.Form namespace topic, I read concerning MessageBox: "In addition to the common dialog boxes, the System.Windows.Forms namespace provides the MessageBox class for displaying a message box that can display and retrieve data from the user." I do not see how the MessageBox class retrieves data from the user. Does anybody ? Perhaps MS had originally intended to use the .NET MessageBox to also allow the retrieving of data, ala the VCL InputBox, and then decided against it. Tag: limited access Tag: 85011

    - BUG: memory retention (leak) in GridTableStyleCollection class There's memory retention (leak) in the GridTableStyleCollection class. This leak only becomes apparent if one creates table styles dynamically. Every time the GridTableStyleCollection.Clear() method gets called it simply doesn¢t clean up the necessary objects and delegates. It¢s not a very serious leak because not many people create table styles dynamically. More can be read at http://blog.vandenhof.org/archive/2004/10/12/150.aspx A program that can reproduce this problem is available for download at http://vandenhof.org/downloads/datagridleak.zip Just run a profiler and have a look at the continued growth of EventHandlerList, PropertyStore, DataGridTextBox objects. The only way to get around this leak is to dispose of the datagrid everytime you switch (newly created) table style objects. I stress, if you use a fixed amount of table style objects this leak won¢t pose a problem. Regards, Marcel van den Hof Tag: limited access Tag: 84990

    - Beta Readers Wanted - Whidbey C# - (O'Reilly Author) This is a one time request for beta-readers for a new book I'm working on. ************* I'm writing a new book on Visual C# 2.0 - target audience is C# 1.x programmers looking to move up to 2.0 (code-name Whidbey). The ideal candidates have been programming in Visual C# 1.x for a while, are familiar with and comfortable with all the language fundamentals, delegates, creating windows and web applications and so forth and are ready to learn what is new in Visual Studio and C# 2.0, as well as highlights of what is new in creating Windows and Web Applications. I will post the chapters after I've written them but before they've been edited or tech-reviewed. Your job will be to provide guidance and advice as to how helpful the chapter is, what is missing, what could be clearer, etc. You can expect to read (and respond to) about 40-50 pages per week through Thanksgiving; starting next week. Ideally, you'll have the Visual Studio 2.0 Beta installed on a computer and will be able to try the exercises, though this is not strictly required. There is no financial compensation (though active participants will receive a copy of the book when it is published, and an acknowledgement in the book itself). You will need to sign a Non-disclosure agreement and you'll need to join a forum on Delphi (membership is free). If you are interested, please send me email (jliberty@LibertyAssociates.com) with your name, email, C# experience, etc. Thank you.

    - DataSets Is there a way to use SQL like terminology but instead of accessing a database use DataSets? I ask because in the current project I am doing there is need to create tables dynamically as results of queries. These tables are then used proceed to the next step. In a server environement I can see where if several people were doing the same task and creating the same table there would be conflicts. So I thought, what if I could generate DataSets and then manipulate them in memory without creating temporary tables in the database to do the work. However, outside of setting up simple parent-child relationships(joins) for DataSets I don't see many options in manipulating relations between datasets. For instance, I would need to create joins between DataSet and tables in a database. I also need to create Cross Joins between datasets. Thank you in advance, Eric Tag: limited access Tag: 84976

    - MenuItem popup event Hey, I have a context menu which is being built dynamically. The menu has regular items and group items which contain sub menu items. I didn't want to create the menu all at once, so I decided I will create the sub menus on the popup event of the parent menu item. The trouble is that the event handler that I registered on popup is never called (I did add a dummy menu item, so the popup SHOULD fire). I tried registering the select event and that 1 works. Any1 has a clue?! MenuItem GroupMenuItem = new MenuItem(FolderName); //create group menu for folder GroupMenuItem.MenuItems.Add(""); //add dummy menu item so it will display as a group and raise the Popup event GroupMenuItem.Popup += new EventHandler(GroupMenuItem_Popup); //assign popup event handler DynamicMenu.MenuItems.Add(GroupMenuItem); //add new group menu when i select the groupmenuitem, the function GroupMenuItem_Popup is never called, altough i checked in debug and onPopup has this function...

And if 1.1 is installed over the top of 1.0, then does it replace it, and if so, does an application developed with 1.0 still run against 1.1?

Register this assembly using RegSvcs /reconfig"; } } Message Class public class MyMessage { public string Forename; public string Surname; } Publisher IMySink sink = new MyEventClass(); MyMessage myMessageObj = new MyMessage(); myMessageObj.Forename = "John"; myMessageObj.Surname = "Smith"; // Code for SerializeThis not included string myMessageStr = SerializeThis(myMessageObj); sink.OnSyncEvent(myMessageStr); Subscriber class SynchronisationSubscriberClass :ServicedComponent, IMySink { private MyWindowsFormClass formWindow; public MyWindowsFormClass FormWindow { set {formWindow = value;} } public void OnSyncEvent (string message) { MyMessage myMessageObj = DeserializeThis(message); formWindow.DoSomethingWithMessage(myMessageObj); } } Problem When the OnSyncEvent method is called in the subscriber the instance of formWindow is null. I presume this is because the code is running in a COM+' s memory space and not the memory space that the rest of the application which instantiated the subscriber is running.

    - Problem in deriving class from XmlNode Hi All, I want to make a custom class in c#, which extends System.Xml.XmlNode class of BCL. Now in custom class, I have implement abstract methods of XmlNode class also. Now when I am trying to run the class it gives an error that "System.Xml.XmlNode.XmlNode() is inaccessible due to its protection level". This error comes because XmlNode has not any public constructor. I found XmlNode has two constructor but both are private or friend (i dont know exactly). I also found one MSDN article where it says that "Never derive any class directly from XmlNode" but its just recommendation. (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/ht ml/cpconextendingdom.asp) Though, Microsoft has derived some of BCL classes from base XmlNode, so why we can not derive? System.Object System.Xml.XmlNode System.Xml.XmlAttribute System.Xml.XmlDocument System.Xml.XmlDocumentFragment System.Xml.XmlEntity System.Xml.XmlLinkedNode System.Xml.XmlNotation So i think there must be some way out of this.... So what to do to create a derived class from XmlNode? I heard that many experts are giving their service in news groups. So please help me out of this. I have already derived few of my classes from XmlDocument, XmlElement, XmlAttribute etc. So i dont want to derive from them but i want to derive the class from XmlNode it self.

It can be done in one way by creating the DirectoryEntry (ActiveDirectory) and DirectorySearcher. But i doesn't want to create ActiveDirectory and after that i should check whether that exists or not. I would like to just check whether user with that pwd exists in the given domain or not. Please help me. Regards, Ramnadh Tag: limited access Tag: 84829

    - System.OutOfMemory exception: error creating window handle Hi, Software: .NET 1.1 (both non-SP and SP1) Visual Studio .NET 2003 MS SQL Server 2000 SP3 Windows XP SP 2 Hardware: Intel Celeron 1700, Pentium 4 2.4GHz, AMD Athlon 1100 RAM 256-512 DDR I've run into a strange problem. There is an application which allows to: 1) connect to a certain device using a modem 2) manage different aspects (mostly, working with MS SQL Server) Serial communication is done on a separate thread, one per each connection. The maximum number of simultaneous connections is 20. Note: what is written below applies only when running the application not under the debugger. The app starts and works correctly: accepts incoming calls, performs different scenarios, dials out when necessary. When the comms thread needs to modify the UI, it is correctly done using Control.BeginInvoke. However, sometimes (on different computers) the following exception is thrown: System.OutOfMemory exception: error creating window handle ---> System.NullReferenceException: Object reference not set to an instance of object. at System.Windows.Forms.ThreadContext.OnThreadException at System.Windows.Forms.Control.WndProcException at System.Windows.Forms.ControlNativeWindow.OnThreadException at System.Windows.Forms.NativeWindow.Callback(IntPtr, Int32, IntPtr, IntPtr) at System.Windows.Forms.UnsafeNativeMethods.IntCreateWindowEx(int32, string, string, int32, int32, int32, int32, int32, HandleRef, HandleRef, HandleRef, object) at System.Windows.Forms.UnsafeNativeMethods.CreateWindowEx(int32, string, string, int32, int32, int32, int32, int32, HandleRef, HandleRef, HandleRef, object) at System.Windows.Forms.NativeWindow.CreateHandle(CreateParams) -- End of inner exception stack trace -- at System.Windows.Forms.ThreadContext.OnThreadException at System.Windows.Forms.Control.WndProcException at System.Windows.Forms.ControlNativeWindow.OnThreadException at System.Windows.Forms.SafeNativeMethods.ShowWindow(HandleRef, int32) at System.Windows.Forms.Control.SetVisibleCore at System.Windows.Forms.Form.SetVisibleCore at System.Windows.Forms.Control.set_Visible at System.Windows.Forms.Form.ShowDialog(IWin32Window owner) at System.Windows.Forms.Form.ShowDialog at <my form-my code to ShowDialog> What could be the problem? Let me stress that this does not happen under debuggers. When debugging, the exception is not thrown. It was noted that this happens more often when having an active connection. -- Regards, Serge (Logic Software) Tag: limited access Tag: 84822

    - Passing parameters to a thread Hi, I'm running into a thread problem. The context is a distributed application constituted of a controller and several satellites performing a given job. In the controller application, I have to send command requests over the network to a list of satellites. In order to parallelize request sending, I'd like to have each request (one per satellite) sent by a single Thread. The problem is how would a given thread know which satellite he should be taking care of since it seems like I can't pass parameters to a thread. My threads can have access to the list (a Hashtable actually) of satellites, but how would a given thread know exactly which one it should be taking care of ? I would need, at least, to pass an index to each thread... Any idea or comment is welcome. Thanks in advance. Arno Tag: limited access Tag: 84816

I will write a service which would be externally controlled by remoting.
But!...
I don't want anyone to be able to control the service, I want only, let say,
sys admin.
How could check the that the remote user credential is sys admin?

Remoting doesn't have a built in solution for this under 1.1 (it will under 2.0). However, you can use the unsupported samples on (IIRC) gotdotnet - there is an SSPI implementation that you can plug into the remoting stack that will allow the user's crededntials to be passed to the remoting endpoint.

When (role based) security is your *main* concern, then a
ServicedComponent (COM+) may be more suitable for you.
Such components can be exposed using IIS+SOAP, so you can
access them from the clients using .NET remoting w/out
messing with COM+ on the client.
