    - .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? Snippet of the offending code in web.config to following in the next post. Many thanks, Mark Tag: Using "c:\Program Files" within initialiseData Tag: 96328

    - 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. In .NetFramework 1.1 there wasn't such problem. Emil. Tag: Using "c:\Program Files" within initialiseData Tag: 96311

    - .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). Thanks, Bria Tag: Using "c:\Program Files" within initialiseData Tag: 96304

    - 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: Using "c:\Program Files" within initialiseData Tag: 96302

    - XSD.EXE Array Generation XSD.EXE generates typed arrays, which are good if you know how many elements you will have, but not so good for unbounded arrays. I am looking for the correct code solution. Currently I have this, which seems uninspired: <code> public class ReportPages { /// <remarks/> [System.Xml.Serialization.XmlElementAttribute("page")] private ReportPage[] page; public ArrayList pages; public void doSerialize() { page = (ReportPage[])pages.ToArray(typeof(ReportPage)); } } </code> I also understand that this relies on the consumer of the code to only add objects of the type "ReportPage".

    - 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: Using "c:\Program Files" within initialiseData 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: Using "c:\Program Files" within initialiseData Tag: 96283

    - 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?

    - when is hashcode used? Hello All, I have been facing this bizarre problem within a combobox having a list of UK postcodes. When I assign the SelectedItem propoerty of the combobox, a completely different item was actually selected in the combobox. I broke into the code at the assignment statement and then looked at the values for different items in the watch window. 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.

    - Implications of using typeFilterLevel=Full after strong naming assemblies Hi, Env: Windows 2003, VS 2003, .Net 1.1 We just started strong naming our assemblies and ran into a .Net Security Exception when remoting between ASP.Net and our Windows service. The remoting call that failed with this exception returns an array of DataRows (from a strongly typed DataSet) from the service to ASP.Net. All our assemblies (apart from Microsft.Security.SSPI sink) are private. The exception is: Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. Exception Details: System.Security.SecurityException: Request failed. Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. Stack Trace: [SecurityException: Request failed.] Anyway, we solved this by setting the 'typeFilterLevel' to 'Full' in our server config file: <formatter ref="binary" typeFilterLevel="Full" /> After some research I found that people have mentioned security and possible performance issues with setting this level to 'Full', so I've a few questions on the implications of opening this up: 1) Why does strong naming a private assembly cause this problem, when an unnamed private assembly works fine? 2) I doubt it, but are there any performance issues? 3) The security issues appear to be from spoofing and code injection: http://blogs.msdn.com/manishg/archive/2004/10/27/248841.aspx Can you please confirm that these security issues existed before we strong named our assemblies and had to set the typeFilterLevel to full? This doesn't mean we'll ignore the vulnerabilities (we already authenticate callers), but we're just trying to understand the impact of this change. Thanks very much, Stuart PS. This is reposted from 'microsoft.public.dotnet.security' as I didn't realise that one wasn't a managed group. Tag: Using "c:\Program Files" within initialiseData Tag: 96178

    - unable to get message from exception I am having a peculiar problem. i have a servicedcomponent class1.method1 with a method (more than 18 parameters). i am calling this from another serviced component called class2.method. When an exception is thrown from class1.method1, the Exception.Message is not visible. when class1.method1 has <= 18 parameter the Exception.Message is visible. what could be the problem. any idea. thanks niranjan Tag: Using "c:\Program Files" within initialiseData Tag: 96176

    - C# Timer control Hi, I have a timer control which writes to a file every 5 seconds but the application closes down before it gets to the second firing of the timer. How can i get the application to stay alive until the next timer interval comes around?

    - InvokeRequired and CreateGraphics Hi, Here is what the documentation of InvokeRequired says : "In addition to the InvokeRequired property, there are four methods on a control that are safe to call from any thread: Invoke, BeginInvoke, EndInvoke and CreateGraphics. For all other method calls, you should use one of these invoke methods when calling from a different thread. " Could someone explain me why a call to CreateGraphics is "safe" ? One of my backgroud threads calls CreateGraphics on a control but when this control is destroyed (ie the application is closed), this thread is blocked on the call to CreateGraphics and isn't aborted. I don't understand why a call to Invoke isn't required in this case. Thanks Fabien Tag: Using "c:\Program Files" within initialiseData Tag: 96167

    - Saving the state of UI Hi, User can adjust the size of columns of a table or the position of splitter in UI. We want these adjustments to be remembered when we restart the application. Currently, we are saving these adjustments by the user in an XML and saving that XML. We read the XML upon restart and make calls to set the adjustments. This approach becomes difficult as we add more controls and more settings can be made by the user. What other techniques can be use to save (perhaps automatically) the STATE OF UI? As in Java, can we use Serialization of UI to save its state [Java's Swings control are serializable while in .Net, Form and all the controls are not serializable]? Any pointers to articles on various approaches to SAVING THE STATE OF THE ADJUSTMENTS made by the user will be greatly appreciated. Thanks in Advance, Regards, Mahesh Tag: Using "c:\Program Files" within initialiseData Tag: 96162

    - Socket and multi-threading Hi, Socket class documentation says that it is not thread safe. We understand that if do simultaneous sends on ONE socket then it will be a problem (or simultaneous receive). Can we create TWO threads on OUR OWN such that one will do SEND and one will do RECEIVE using the SAME socket reference? This means that two threads WILL BE in the same SOCKET object - one doing receive and one doing send. We know we can use asynchronous calls on the socket to achieve this but whether we can do this using our own threads. Any pointers to official documentation that shows that this is permissible? Thanks in advance, Regards, Mahesh Tag: Using "c:\Program Files" within initialiseData Tag: 96161

    - Datagrid Load data Problem Can i user dataset partially load the data to datagrid depends on the scoll bar moving? seems like power builder have this function of the data browser/windwows (i forgot), but it can partially load data to grid. So can someone know the method in VB.Net? Tag: Using "c:\Program Files" within initialiseData Tag: 96158

    - Forms, multi-threading, Chats We are building Chat like application using Forms and as a result our programming is becoming complicated to display messages received on different threads in the chat window (due to STA requirements of Forms). Is there a way to build Chat like application WITHOUT using FORM, so that one can use free threading model (The link http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpcondevelopingmultithreadedwindowsformscontrol.asp has statement "Outside Windows Forms, classes in the .NET Framework use the free threading model. For information about threading in the .NET Framework, see Threading."). IS THERE ANY WAY TO BUILD CHAT-like application without having to do complicated programming to satisfy STA requirements)? Thanks in Advance, Regards, Mahesh Tag: Using "c:\Program Files" within initialiseData Tag: 96155

Is there a known issue where a Configuration exception is thrown when
"Program Files" is used as part of the initialiseData value:

<system.diagnostics>
<trace autoflush="false" indentsize="4">
<listeners>
<add name="myListener"
type="System.Diagnostics.TextWriterTraceListener"
initialiseData="C:\Program Files\log.log"/>
</listeners>
</trace>
</system.diagnostics>

Thanks,
Mark
