    - .net 2.0 beta DetailsView question I've been going through the basic tutorials in .net 2.0 regarding the creation of master/detail pages and using the DetailsView control to edit records. It's all pretty simple in the tutorials. But what if you want to check for database errors? How do you put all the database interaction into a try/catch block? In an ideal world, all of the database constraints would be duplicated in validation controls, so the form could only submit valid data. But I would like to make sure that, if somehow the database rejected the input, this could trigger a friendly error message to the user and possibly an alert to the administrator.

    - Using assemlby without depending on it I am trying to use a 3rd party assembly that may or may not be available on a given machine. Is there a way I can use the classes within that assembly without it throwing an assembly load exception when the assembly file is not available? I want to safely bypass the feature if the assembly is not there. I was going to try using the Assembly a = Assembly.Load() but there are a lot or properties and method that I need to use. It would take forever if I manually called GetMethd(), GetProperty(), and Invoke for every value I needed. -- Bill Tag: How much do MemoryStreams grow by when they expand? Tag: 96355

    - GC Bug .net 2.0.50215 Async functionality prevents an object from garbage collection. To reproduce: Create a socket establish connection Create NetworkStream with Ownership Of a socket (or just work socket directly) Call BeginReceive on stream or socket dereference network stream The conneciton will stay up until parent process is terminated. What GC should be doing is releasing a handle of an underlying socket which it does not. pseudo code: void init() { init socket socket.connect() init networkstream(owns the socket) networkstream.beginread(async parameters) } void main() { for (int j = 0; j < 100; j++) { init(); } GC.Collecti(); GC.WaitForPendingFinalizers(); break here (console read) } netstat will show 100 established connections that will never go away.

    - Windows service with console I'd like to write a windows service in .net, in itself that's not a big deal, but my problem comes from the fact that I'd quite like to have the ability to have a console attached to the service. The reasoning behind it is that Iâ??d like to have the option of some user input, but if they do something stupid (namely shutdown the service) it will restart itself and continue, plus it would be useful to have some screen logging, just the sort of stuff that is more than I want in the event log (start stop, error) but not the sort of level of detail that will be in the file logs, which is too much for the average service engineer to trawl through. I thought I read somewhere that there was a property along the lines of HasConsole, but I canâ??t find it, it what Iâ??m trying possible of do I need to write a trace listener to listen for information from the service? Thanks for any help. Rob Tag: How much do MemoryStreams grow by when they expand? Tag: 96352

    - GC and active sockets I'm using .net 2.0 beta2 and noticing some strange behaviour around socket garbage collection. Problem: If a socket is a part of a class which has been instantiated, socket connected, and class de-referenced Socket will stay connected forever. Environment: Sockets are doing async read/write Question: How do i get it solved :) also - is putting something on IOCP thread will cause garbage collection to fail because of internal blocking that is going on. How can i clean up connected socket which is a member of a class which suddenly lost refernece. Under normal conditions I do clean up, however, there are scenarios where abnormal termination of a thread can cause socket's parent class loose reference.

    - aspx stops working after the 1.1 framework is installed Access to my aspx pages stopped working on my development machine. I tried everything I know to get it to work such as re-registering iis with aspnet_regiis -i -enable with no luck. So I bit the bullet and uninstalled VS2003 and IIS from my XP SP2 machine. I reinstalled IIS and the aspx's ran, I then installed the 1.1 framework and they stopped working. I even tried installing the service pack with no luck. When I try to run an aspx page I hear a bell with no message on the screen. I see disk activity and the inetinfo.exe process is running at 99% in task manager. Has anyone encountered this problem and know how to fix it? At this point my ASP.Net development is stopped. Tag: How much do MemoryStreams grow by when they expand? Tag: 96339

    - .NET Framework 2.0 Beta 2 install issue Hi, While installing Visual Studio 2005 Beta 2 for C#, the .NET framework 2.0 Beta 2 install doesnt complete and hangs. The problem started when my laptop went into Hibernate mode during the install (the battery ran low). On resumption, the install just hangs. After several restarts and shutdowns, the problem still persists. I cleanedup the registry of any .NET 2.0 entires (such as in the HKLM/Software/Microsoft/.NETFramework, etc.). I also renamed the MSCoree.dll, etc. The only clue I have so far is that when I try to UNINSTALL .NET framework 1.1, I get a message that say something like: Error 1704: .NET 2.0 Beta 2 install has made updates and is suspended. Undo the changes before proceeding. There is a button for undoing the changes, but when clicked it pops up a window that hangs. Appreciate any help.

    - Exception in configuration section handler Hi All, I have an error occurring in my web.config file. It occurs when the application restarts and it only occurs once. A simple browser refresh clears the problem. It only happens in our development staging and testing environments (Win2K) but not in my development environment (WinXP) I would like to do two things: 1. Handle this exception gracefully (perhaps in Application_Error?) 2. Fix the cause of the problem. Can anyone help with either?

    - keyboard capture I've written a simple application. It consists of main window, menu and a label. I added event handler to the main form (KeyDown), so when I push a key on the keyboard, then it's key code should be displayed using a label (label.Text = e.KeyCode). It works fine with "A", "B" etc. but when I press left arrow, up arrow etc, the main menu popups and KeyDown event is not handled. What should I do ? PS. I use .NetFramework 2.0 Beta2.

    - .NET Application does not release memory until minimized Hello, We have a local .NET application running against a local MSDE database. When the application is checking out data from the local MSDE SQL Server the procesor spikes, and the memory continues to grow. Once the application data is loaded from SQL into memory the application stays peaked at 300+MB. It will never reduce from this size (even over 20 minutes or so) until the application is minimized and then maximized. At this point the application resets to it's initial memory size and the available memory slowly creeps back to a normal level. This is causing all sorts of miscellaneous program errors because memory is tied up and not being freed again. Any ideas on how to get the .NET Applicaition to give back the memory it is not using? We're using .NET Framework 1.1, Visual Studio VB.NET 2003, MSDE 2000 with SP3a, on Windows XP SP1 and Windows 2000 Professional SP3 (same behavior on both Operating Systems).

    - Socket Broadcasting with Multiple Adapters I'm getting some weirdness when sending out broadcasts on a system with two adapters. The adapters are configured with IP addresses on seperate subnets. Packets get sent out on each interface, but the source addresses (as seen from a packet sniffer) on both packets is the IP address for adapter #1. This creates a problem when clients on adapter #2's network try to respond because they can't reach the source address on adapter #1's network. Here's some code that illustrates the problem: public static void Main(string[] args) { byte[] bytes = Encoding.UTF8.GetBytes("Testing broadcast..."); IPEndPoint endpoint = new IPEndPoint(IPAddress.Broadcast, 10485); Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); socket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Broadcast, 1); socket.SendTo(bytes, endpoint); } My question is, am I doing something wrong? Or is this expected (or even desired) behavior? If so, any ideas how I could make it work correctly? Tag: How much do MemoryStreams grow by when they expand? Tag: 96302

    - Terminal Service and Allow service to interact with desktop Hello, I have developed a Windows Service using C# that interacts with an external application. The external application is used as monitor for the Windows service and is launched from the service using "Start" method of the Process class. The external application is a C# window form with a "system tray" icon. On XP, 2000, and even 2003, everything works great and the icon is displayed in the system tray... But when the user is logged into terminal services, the icon is not displayed in the system tray. We really need this icon to display in the system tray in all cases, but do not have a clue on how to get it to display while logged in under "Terminal Services"... Does anyone know what needs to be done in order to get this to work? We really appreciate any help you can give. Thank you Tag: How much do MemoryStreams grow by when they expand? Tag: 96290

    - monthCalendar DateChanged issue - documented behaviour? I've searched for this problem but haven't found any posts on it - hope this isn't a duplicate... I had a strange event occur earlier today and have isolated the 'problem'. In its simplest form I have a monthCalendar control and textBox control on a form, and have added an event handler that clears the text in the textBox when the DateChanged event is fired. The problem is that I find if text is entered in the textBox, after just under 2 minutes (on my system) the DateChanged event is apparently fired (even if no activity is occurring) and the textBox will be cleared. To isolate this I went back to the DateChanged event handler example in the MS docs and stripped the code down (also changing some of the values for sizes and alignments). Here's what I have: using System; using System.Drawing; using System.Windows.Forms; public class Form1 : System.Windows.Forms.Form { private System.Windows.Forms.MonthCalendar monthCalendar1; private System.Windows.Forms.TextBox textBox1; [STAThread] static void Main() { Application.Run(new Form1()); } public Form1() { this.textBox1 = new System.Windows.Forms.TextBox(); this.textBox1.Location = new System.Drawing.Point(248, 16); this.textBox1.Multiline = true; this.textBox1.Size = new System.Drawing.Size(224, 32); // Create the calendar. this.monthCalendar1 = new System.Windows.Forms.MonthCalendar(); // Set the calendar location. this.monthCalendar1.Location = new System.Drawing.Point(47, 16); this.monthCalendar1.DateChanged += new System.Windows.Forms.DateRangeEventHandler(this.monthCalendar1_DateChanged); // Set up how the form should be displayed and add the controls to the form. this.ClientSize = new System.Drawing.Size(500, 266); this.Controls.AddRange(new System.Windows.Forms.Control[] {this.textBox1, this.monthCalendar1}); this.Text = "Month Calendar Example"; } private void monthCalendar1_DateChanged(object sender, System.Windows.Forms.DateRangeEventArgs e) { // If the date changes, clear the text box this.textBox1.Text = ""; } } Is this behaviour documented anywhere? I assume that I'm merely using the wrong "tool" and should be monitoring a different event or clearing the textbox differently, but this still seems very odd to me. I initially set this up with Visual Studio 2005 Beta 2 but tested the above in SharpDevelop. Any insight would be appreciated. -- Jeff Tag: How much do MemoryStreams grow by when they expand?

    - Crystal Report external formatting Hi, I'm working on a project of creating reports using MS Visual Studio 2003 and Crystal 10. An XML with all the data will be passed to the program for generating the report. Since we're applying this to quite a few clients, I'm wondering if there's a way to have an external formatting file (like CSS) that we can load to the report at runtime to customize the fonts and colors of the fields? I know that you can setup the CSS Class for viewing the report through the web. But is there any other method that doesn't go thru the web?

    - Memory Management I have an .NET application that calls a DLL compiled with a fortran compiler. Users are having a problem that the fortran DLL complains that is unable to allocate memory when the arrays it is using are too big. After reading around I decided that increasing the MaxWorkingSet for my process may help. However, the Fortran DLL fails (when it tries to allocate memory for an array containing abotu 900Mb of data) before it gets to this MaxWorkingSet value (about 1400Mb). So, to try and get an understanding of this I tried to set the MaxWorkignSet to about 500Mb. However, the fortran DLL is quite happily able to allocate memory for an array that contains several 100Mb over this value. During this, looking in the task manager I aslo see the peak memory usage has also gone well over the MaxWorkingSet value. Can someone explain to me what MaxWorkignSet really means? And is there anyway I can get windows to let the fortran DLL allocate more memory? Since someone is sure to ask, the fortran DLL contains a subroutine that implements a mathematical model and I have now control over its desgn or how much memory it tries to allocate.

    - C#2.0 Form to COM object? I have a standalone app created in C# that is used to browse a database of archived documents called DocDB. We have some older legacy code written in Delphi that we wish to enhance with the DocDB's functionality. My idea was to give DocDB methods for controlling it from a seperate process via COM (much like Word for example, but with only a few public methods) I have defined public methods in my forms based class, I have used an SNK file, I successfully installed it into the GAC and run regasm. I have also created a public interface for the few methods I need. But no matter what I have done, the TLB that I create never exposes the public methods when imported into my legacy app. The code looks something like this (using C# 2.0): namespace DocsDB { [Guid("3100EBCE-1E40-500b-A247=AD-C777D72BB2ED")] public interface IDocsDBUI { void ViewDocsForLoan(int loan); void IsVisible(bool visible); void Quit(); } [Guid("AA218A41-ED34-5f4e-95C1=AD-0F1DB0402AD9")] [ProgId("DocsDB.App")] [ClassInterface(ClassInterface=ADType.AutoDual)] public partial class frmMain : Form, IDocsDBUI { public frmMain() { InitializeComponent(); } public void IsVisible(bool visible) { this.Visible =3D visible; } public void Quit() { this.Close(); } public void ViewDocsForLoan(int loan) { // do something here } } } Can someone tell me what I might be doing wrong?

It looked something like this : postcodeObj : EH11 1LQ comboBox1.SelectedIndex = -1 (nothing currently selected) comboBox1.Items.IndexOf(postcodeObj) : 1614 comboBox1.Items[1614].ToString() : EH11 1LA (something different to what i am intending to set as selected item) I also found out that my item was at the location 1621 in the combobox items. The combobox is no sorted, and I couldn't figure out what was going wrong here, till I added 2 more things in the watch window comboBox1.Items[1614].GetHashCode( ) comboBox1.Items[1621].GetHashCode( ) These 2 values appeared to be same, Now I remember that I have overriden the GetHashCode() method in my postcode object to return a hashcode, it creates a hashcode based on the postcode string and one more attribute. (XOR the number and the hashcode of the string) My question is, Is hashcode used internally by the 'SelectedItem' set method? Is there any way for me to get round this problem? I have the postcode strings and a unique number, Can I generate a unique hashcode from this combination? I don't want the number to be my hashcode.

    - RST packet, TCP session does anyone know of a way to set TCP control flags (specifically RST) on existing socket with active IPv4/TCP connection SetSocketOption allows for urgent flag but not RST? For that matter, set TCP_WAIT to 0 (please don't post about TCP_WAIT being there for a reason, I know all about it and it is not applicable in my case).

    - Reflection: accessing member of given object Hi, I have trouble finding info on the following: I have an object myDataAccessObject that contains heaps of SQLDataAdapters and derivatives thereof. These are auto-generated for me by VS. I want to be able to call the update-method on all of these (in effect doing a database-dump) with myDataSet as input (since that's where my data is). now I *could* put all the adapters into a list and loop through them, calling the update method, but that's not pretty and I will have to manage that list as the DB expands so I don't want to do that. basicly I want to: -get all sqladapters from myObject -call "Update" with parameter myDataSet on all of them that shouldn't be so hard, yet I am stuck and am finding no docs on it. yours Andreas Knudsen Tag: How much do MemoryStreams grow by when they expand?

I believe it always doubles, and that's not configurable.

there is a simple way to configure that: write your own stream!
it's not that much difficult, but if you are daunted, just grab the mono or
rotor source and start hacking from them....
