    - INSERTing long TEXTs into MSSQL 8.00.2039 Hi, I have a table with columns of types datetime, varchar, text, text, text, text. The text columns will contain XML documents, there is no primary key in the table but they varchar column contains foreign keys. If I insert trivial text values like "hello" everything works fine but when I use real XML documents weird things start to happen. The row gets inserted with no error message but when I view it in enterprise manager the particular column that was supposed to contain the XML document is empty (the datetime and all text columns with trivial values like "hello" or "world" is correctly displayed). After some experimentation I noticed that it appears to be the length of the text field that determines whether that column will get a value or not. For text values of length 900 chars and shorter it's no problem, but for text values with a length of 901 chars that column will not be set but instead empty. The actual content of the long text value does not matter, I tried to insert a 900 char string of the letter "c" only and that worked, while 901 consecutive "c" chars causes the row to be inserted with a empty value where the string of "c"s should have been. My question is, how can I insert TEXT values longer than 900 chars? I know this datatype should handle alot longer values... FWIW; I'm using MSSQL 8.00.2039 and I'm doing the INSERTs using standard .NET component (ver 1.1) such as SqlConnection and SqlCommand. regards, martin Tag: Using ManualResetEvent within a ContextBoundObject Tag: 113850

    - callback supplied to Socket.BeginSend never gets called Iâ??m having troubles with socket async operations using .NET 2.0. Sometimes a callback supplied to Socket.BeginSend never gets called. I suspect this can be caused by AVG Antivirus or MS AntiSpyware running on the PC, because if I suppress them, everything goes fine. Unfortunately, I was unable to reproduce the issue in isolated environment as the problem has been reported by one of our customers who experiences it in irregular way. Iâ??ve only managed to track it down to Socket.BeginSend and the callback using our logging system. Is it a known issue with Socket in .NET 2.0? Is there a fix to solve this problem? Thanks in advance! Any help would be highly appreciated. Tag: Using ManualResetEvent within a ContextBoundObject Tag: 113846

    - Generic Lists Desing Issue Generic Lists are great! But I think you missed a opportunity. Here is my problem. I made a Collection "Family: List<Person> " which will contain 'Family'. I wanted to override the Add method so you can only add persons whose Parents or Childeren are already in the list, but the Add method is not virtual! The Add method of Arraylist is virtual and I see no reason for the generic counterpart not to be. My work around is to create my own GenericList that has a private List<T> and duplicate all IList<T> members and make them virtual, but still it should have been there all along. I see no reason why List<> or all other generic collections have no virtual methods, is there? Maybe speed, but that wasn't an issue with ArrayList so it shouldn't be with generic collections either.

    - Threading problem in local COM server We have defined a COM object in C# on the .Net platform (v2.0.50727) in an out-of-process server (.exe). This COM object, in one of its methods, creates a WebBrowser control (AxSHDocVw.AxWebBrowser). The main application can successfully create an instance of this object, but when trying to call the method creating the WebBrowser control, an exception is thrown stating that System.Windows.Forms: ActiveX control '8856f961-340a-11d0-a96b-00c04fd705a2' cannot be instantiated because the current thread is not in a single-threaded apartment. The Main() function in the COM server has the [STAThread] attribute set, and we checked that this thread actually runs in a single thread appartment. The constructor of the COM object is also called on this thread, in STA. The method creating the web browser control, however, is called on another thread, which indeed runs in MTA. We did not create this thread, nor did (willingly) specify somewhere that a thread should be created, and so we do not have control over the apartment of that thread. I don't know whether it is relevant, but the class factory of the COM object is registered with the flags CLSCTX_LOCAL_SERVER, REGCLS_MULTIPLEUSE, after which the Main() function goes on to accept COM requests by calling System.Windows.Forms.Application.Run (); I'd be very grateful for any clues or hints.

    - Decimal/Single/...: which Numeric-type to use? Hi, I'm having some troubles with my numeric-types in my VB.NET 2005 application, together with a SQL Server 2000. - I first used Single in my application, and Decimal in my database. But a Single with value 4.475 was converted to a Decimal with value 4.4749999999999996D. So after inserting and selecting it from the database I got another value than the original! - So I used also the Decimal in my application, but now all my numbers are formatted with all the decimals: when my value is "1", it shows "1.0000". A single value roudns it nicely to 1, but the decimal value shows the whole decimal part, even when it isn't needed. What I need is: the users should only see the decimal part when needed, AND my values have to be the same (no 4.475 to 4.474999999999 changements). This seems such a simple and basic need, but I just keep having troubles with it :-( What should I do/use? Another numeric datatype in my application? Another datatype in my Database?? Any help/hints/links/information would be really appreciated! Thansk a lot in advance, Pieter Tag: Using ManualResetEvent within a ContextBoundObject Tag: 113832

    - WebRequest & proxy problem In my auto-update code I donwload some files from the net with a WebRequest. Some people having a proxy server reported problems. IN a previous application I set the WebRequest wr = ....; wr.Proxy = WebProxy.GetDefaultProxy(); Which read proxy info from internet explorer. Great, exactly what I want. But this method is now, in 2.0, apparemtly obsolete. What could I use? I read somewhere that someone suggested WebRequest.DefaultWebProxy, but that's crazy, why set it if it's the default already? I saw also the NetSectionGroup.DefaultProxy propery. So now, what should I do? Problem is I cannot test, we are not using proxy here .... :S and I don't really know they work....

    - Page state on postback Hi, This is a pretty straightforward question about postback, etc. in C# ASP.NET. I have 3 DropDownLists, each is bound to a SQL DataTable, created from 3 SQL queries. If the user makes a selection from a DropDownList, an auto-postback event is triggered. But, the DataTables, which are members of my Page class, become null on the postback. I don't want to lose that DataTable information. There's more info in the DataTables than the DropDownLists, which is why I want to keep them around. So, does this mean I need to recreate the DataTables somehow and rebind , such as repeating the SQL queries and rebinding, or serializing the data somehow? I'm just trying to figure out the limits of what .net does for me. Is it limited to setting the state of controls on postback? I'm aware of how Session["var"] and ViewState["var"] work, I just wanted to see if I'm overlooking something, like some trick to keep variables in the Page class around between postbacks. At this point it seems like caching the SQL queries to recreate to DataTables is my best bet. Lemme know if I'm missing something.

    - Can't cancel the validation when the control lost focus to a userc I have problem with a control when its causesValidation property is set to true. It is actually happens in .NET Framework 1.1. When I lost focus from this control to another control within a user control by clicking the target control, I can't really cancel the validating event. It won't happen if I move the focus to other control within the form, or within the same container of the source control. another different behavior when the application is ran in Terminal Server. + Steps to Reproduce: Let say the source control is a textbox and the target control within a usercontrol is a checkbox. When I click the checkbox, the checked value is changed and so does the validating event of the source control. So, the focus remains in the source control, but the target control is excecuted too. Sample application is in: http://www.geocities.com/dikhi/downloads/WindowsApplication2.zip + Actual Results: In Windows XP: The focus remains in the textbox, but the checked value of the checkbox is changed. In Terminal Server: The focus is moved to the target control. + Expected Results: In WIndows XP: The focus is still in the source control (already correct), but The target control (checkbox) shouldn't change its checked value. In Terminal Server: The same as the Windows XP Many thanks in advance. Tag: Using ManualResetEvent within a ContextBoundObject Tag: 113814

    - NetworkStream with CryptoStream help Hi all, I've some problems using NetworkStream with CryptoStream. I create a simple server/client projects and I think the problem is in cryptoStream. If the server sends data using networkStream, the data is sended. But if the server sends data with cryptoStream the send process stops because it needs to feel all the client read buffer. In this way, only closing the socket the message is sent. If the client buffer is small the server sends the message. The same problem happens in client. If client read using networkStream, no matter what stream server is using to send or the client buffer size, the client receives the message. But if client uses cryptoStream, it blocks.

    - Overriding generic methods - compiler hides wrong method I think there is a problem with the compiler when overriding a generic method in an inherited class. I have a base class with a non-generic method "Foo(string arg)" and a generic method "Foo<T>(T arg)" (identical names). Now I create a new class that inherits from that base class. In this class I override the generic Foo<T> method (using "new"). If I make a call from the inherited class to this.Foo("abc") (which should invoke the non generic method in the base class, as that method is not overridden), something strange happens: Not the non-generic method in the base class, but the generic method in the derived class is invoked. The problem only occurs if I hide a method using new. If I override a virtual method, everything is fine. To clarify, consider the following 3 classes and the comments behind the code with the strange behavior: public class Base { public Base() {} public int Foo(string arg) { return 1; } public bool Foo<T>(T arg) { return false; } public bool Boo(string arg) { return true; } public bool Boo<T>(T arg) { return false; } } public class Derived : Base { public Derived() :base() {} public new bool Foo<T>(T arg) { string s = ""; int i1 = this.Foo(s); // Does not compile (expects bool) ! int i2 = base.Foo(s); // OK (calls Base.Foo(string arg)) int i3 = ((Base)this).Foo(s); // OK (calls Base.Foo(string arg)) return base.Foo<T>(arg); // OK (calls Base.Foo(T arg)) } public new bool Boo<T>(T arg) { string s = ""; bool b1 = this.Boo(s); // StackOverflowException (calls Derived.Boo<T>(T arg)) ! bool b2 = base.Boo(s); // OK (calls Base.Boo(string arg)) bool b3 = ((Base)this).Boo(s); // OK (calls Base.Boo(string arg)) return base.Boo<T>(arg); // OK (calls Base.Boo<T>(T arg)) } } public class Derived2 : Derived { public Derived2() : base() {} public new bool Foo<T>(T arg) { string s = ""; int i1 = this.Foo(s); // Does not compile (expects bool) ! int i2 = base.Foo(s); // Does not compile (expects bool) ! int i3 = ((Base)this).Foo(s); // OK (calls Base.Foo(string arg)) return base.Foo<T>(arg); // OK (calls Derived.Foo(string arg)) } public new bool Boo<T>(T arg) { string s = ""; bool b1 = this.Boo(s); // StackOverflowException (calls Derived2.Boo<T>(T arg)) ! bool b2 = base.Boo(s); // StackOverflowException (calls Derived.Boo<T>(T arg)) ! bool b3 = ((Base)this).Boo(s); // OK (calls Base.Boo(string arg)) return base.Boo<T>(arg); // StackOverflowException (calls Derived.Boo<T>(T arg)) ! } } Is this a bug or a wanted feature?

    - DataGrid on Update does not pass back values via e.Item.Cells[] I am creating a generic DataSet update interface in VS 2003/ASP .NET. I have an DataGrid that has AutoGenerateColumns = true and set whatever DataSet i was to modify as the DataGrid.DataSource. Viewing, Editing and Cancelling work, Updating values after an Edit does not. When I click the Update button on the DataGrid, the UpdateDataGrid event fires. In the Update DataGrid function i loop through the e.Item.Cells[] and attempt read out all the values from the Controls. (eg. ((TextBox)e.Item.Cells[i].Controls[0]).Text) For some reason all the Controls values are the empty string ("") even though i updated the information on the web front end. What could be causing all my Control values to be empty? Also, e.Item.Cells[i].Controls[0] is of type System.Web.UI.WebControls.TextBox.

    - GSSAPI bindings for C#/.NET All, I was able to find an IETF document proposing some specifications for GSSAPI C# bindings (http://www.ietf.org/internet-drafts/draft-ietf-kitten-gssapi-csharp-bindings-00.txt), but I was unable to find any suitable implementation. The goal is to use MIT Kerberos to authenticate to remote services. Anyone have any pointers on this? I'm beginning to feel like the best bet will be to P/Invoke the MIT Kerberos libs to do this, but it seems like a pure .NET implementation would obviously be preferable. There are some Novell-namespaced classes in the most recent mono class sources that seemed to bear some resemblance to these IETF bindings, but these just seemed to reference Java classes to provide the actual implementation. Further to this, is it possible to use some facilities of the System.DirectoryServices namespace to communicate with remote kerberized services without your KDC being AD?

    - Does clickonce work well? Any disadvantages? We have an ASP.NET web application that gets installed on a server in a hospital and then any computer throughout the hospital's network can access the application. I prefer Winforms applications to ASP.NET, so I am thinking that we should replace our current one with a Winforms application distributed through clickonce. What are the disadvantages of doing this? I am having difficulty convincing my coworkers that clickonce will distribute just as easily as a web application. It seems to me that the major disadvantage is that the client PC has to have the .NET framework on it, which won't be the case in general. Does clickonce work really easily in general?

    - Different execution behavior between .Net1.1 and .Net2.0 I have a library that reads PDF file and manipilates its content. And I use SharpZip library to decompress the streams included in PDF file. All well and good. I have 3 lines of my test code that takes a PDF file and spits out the required content from the file. It all works fine in .Net.1. environment. Now I wrote the same 3 lines of code in .Net2.0 console test application and use the assemblies for PDF library and SharpZip compiled with .Net.1.1. The application will throw exceptions in the deflate algorithm "Index out of bound". Then I tried to replace the SharpZip decompression code with DelateStream class in .Net2.0 framework, recompiled pdf library and sharpzip assemblies with .Net2.0. But still no luck. Is there something I am missing in this whole equation of using my 1.1 libraries with .Net2.0 application? Thanks Tag: Using ManualResetEvent within a ContextBoundObject Tag: 113801

    - How do I add existing visual Item to a project Hello!! Normally I use C# but we have a project that is creating a window control library DLL that is done in C++.NET and that is here I have some problems that I want to solve. To be able to understand my question fully, I do the following. 1. Create a project that is a WindowControlLibrary called Test in C++.NET in this project we have several files but the following are intresting for me. Under Source Files we have a file called TestControl.cpp Under Header Files we have a file called TestControl.h and if you expand this file you can see TestControl.resX. 2.Open View Designer for TestControl.h and add for example a button. 3. Everything works as it should so far. 4. Now delete file TestControl.cpp and TestControl.h from the project Test. When file TestControl.h was deleted, file TestControl.resX was also deleted because it was connected to TestControl.h 5. The files still exist in folder Test but does not exist in project Test. 6 Now assume that you want to add these files(TestControl.cpp, TestControl.h and TestControl.resX) back into project Test again. 7 I have tried different variation for Add Existing Item for my three files to project Test but all my attempts failed in the way that I can never open View Designor. 8 So how do I do if I want to add an existing visual control like the TestControl. 9 It works perfectly to add new Item which I do in this way click on Source File and select add New Item and choose for example User Control. //Tony Tag: Using ManualResetEvent within a ContextBoundObject Tag: 113790

    - Problem with custom collections. Hi, I have used the collectionbase to create two different collections. One various button clicks, I add values into these collections. I'm having a problem, though, for as soon as I add more than one item to the collection, I am only able to retrieve the most recent item I've added. For example, when I debug, and look at the collectionbase list, I only see the "raw value" for all my items, except for the most recently added item. Any thoughts? Note: I am running this on the Compact Framework 2.0 -- from what I've seen, though, there shouldn't be anything different from the regular Framework 2.0. Here is the code I'm using: public class PolygonPoints : CollectionBase { public PolygonPoints() { } public PolygonPoints(PolygonPoints coll) { this.InnerList.AddRange(coll); } public Point this[int index] { get { return ((Point)List[index]); } set { List[index] = value; } } public virtual void Add(Point item) { List.Add(item); } public virtual void Insert(int index, Point item) { List.Add(item); } public virtual void Remove(Point item) { List.Remove(item); } public bool Contains(Point item) { return List.Contains(item); } public int IndexOf(Point item) { return List.IndexOf(item); } public void CopyTo(Point[] array, int index) { List.CopyTo(array, index); } protected override void OnValidate(object value) { base.OnValidate(value); if (!(value is Point)) { throw new ArgumentException("PolygonPoints only supports Point objects."); } } } public class Polygons : CollectionBase { public Polygons() { } public Polygons(Polygons coll) { this.InnerList.AddRange(coll); } public PolygonPoints this[int index] { get { return ((PolygonPoints)List[index]); } set { List[index] = value; } } public virtual void Add(PolygonPoints item) { List.Add(item); } public virtual void Insert(int index, PolygonPoints item) { List.Add(item); } public virtual void Remove(PolygonPoints item) { List.Remove(item); } public bool Contains(PolygonPoints item) { return List.Contains(item); } public int IndexOf(PolygonPoints item) { return List.IndexOf(item); } public void CopyTo(PolygonPoints[] array, int index) { List.CopyTo(array, index); } protected override void OnValidate(object value) { base.OnValidate(value); if (!(value is PolygonPoints)) { throw new ArgumentException("Polygons only supports PolygonPoints objects."); } } } Here is how I am adding data into my collections: PolygonPoints alCurrentPolygonPoints = new PolygonPoints(); Point arrayPt = new Point(1,1); alCurrentPolygonPoints.Add(arrayPt); And: Polygons htPolygons = new Polygons(); htPolygons.Add(alCurrentPolygonPoints); Tag: Using ManualResetEvent within a ContextBoundObject Tag: 113779

    - VbScript Function to encode into base64 compatible with .NET function System.Convert.FromBase64String I am using the following code to convert a byte array in vbscript which is passed to a web service: Function ByteArray2Text(varByteArray) 'Convert byte array into a string with VBScript '60kb = 2 seconds, 100kb = 5 seconds, 200kb = 25 seconds Dim strBuffer, lngCounter strData = "" strBuffer = "" For lngCounter = 0 to UBound(varByteArray) strBuffer = strBuffer & Chr(255 And Ascb(Midb(varByteArray,lngCounter + 1, 1))) 'Keep strBuffer at 1k bytes maximum If lngCounter Mod 1000 = 0 Then strData = strData & strBuffer strBuffer = "" End If Next ByteArray2Text = strData & strBuffer End Function I need to decode it with .NET.

    - Reflection getting MissingMethodException I am trying to use reflection to dynamically call a method. I have an "interface" object that is inherited by the object that I am trying to invoke. The interface object contains virtual methods that throw a custom NotImplemented exception. The actual class overrides these methods, the end goal is to loop through each method to see which ones throw the NotImplemented exception. Here is the code that I am using to dynamically invoke to method: Type InterfaceType = typeof(Interfaces.MainInterface); System.Runtime.Remoting.ObjectHandle hobj = null; object[] arguments = new object[0]; hobj = Activator.CreateInstance("Interfaces.MainClass1","Interfaces.MainClass1"); object result = InterfaceType .InvokeMember("myMethod",BindingFlags.Instance|BindingFlags.Public|BindingFlags.InvokeMethod,null,hobj,arguments); When I run the code I get a MissingMethodException exception saying it can find method Interfaces.MainClass1.myMethod Everything looks clean, any thoughts?

Database: Sql server 2000 I have an MS DATALIST which has Item Templates, show the image and the price right next to the "PRICE" text. the image name and the Price is being populated from the datbase. All i do it get a datatable frm the database and set it to the datasource of the grid it autoppulates it. The code in the HTML section of the page for the grid which tells what fields are to be writen and where to write them is : <HeaderTemplate> </HeaderTemplate> <ItemTemplate> <TABLE height=126 width=194 border=0> <TR> <TD><IMG height=136 src='<%# DataBinder.Eval(Container.DataItem, "ProductImage") %>'></TD> <TD class="plaintext">PRICE : '<%# DataBinder.Eval(Container.DataItem, "price") %>'> </TR> </TABLE> </ItemTemplate> Now i want to add another field in their from the datatable which will haev the sale price, and if their is a sale price for an item only then the Class prperty of the PRICE Value should be "StiredNormalText" so that the price is striked out and the the Sale price should appear benath it, once again if their is no saleprice for an item then the CLASS of the Lable only for that item should be "plaintext" and if their is then it should be "StiredNormalText". their coudl be multuple records in the datatable. how can i do this, can it be done?

    - Wrong size when restoring form that has no WS_DLGFRAME style flag set Hello, I have a form that I don't want to display the title bar for. The way I've implemented this is to to remove the WS_DLGFRAME style flag. However, when this form is minimized and then restored, it is restored to the wrong size. The height of the form increases 19 pixels (height of a title bar on my computer) with every minimize/restore. Can someone shead any light on this? I've attached an example program. To reproduce, just create a standard windows forms project, paste the code, and add a button to the form whose click handler you connect to the button1_Click method. public partial class Form1 : Form { public Form1() { InitializeComponent(); } // Attach this to a button click event for a button on the form private void button1_Click(object sender, EventArgs e) { if (IsStyleFlagSet(this.Handle, WS_DLGFRAME)) { // Remove caption bar SetStyleFlag(this.Handle, WS_DLGFRAME , false); // Repaint NC area SetWindowPos(this.Handle, IntPtr.Zero, 0, 0, 0, 0, SWP_FRAMECHANGED | SWP_NOSIZE | SWP_NOMOVE | SWP_NOZORDER); } // Get my current client size Size prevSize = this.ClientSize; // Minimize and restore me this.WindowState = FormWindowState.Minimized; this.WindowState = FormWindowState.Normal; // Get my client size now Size currSize = this.ClientSize; if (currSize == prevSize) MessageBox.Show("Size was equal! :-) "); else MessageBox.Show(string.Format("Size was not equal! :-(. Before: {0}, After: {1}", prevSize, currSize)); } // Style constants internal const int GWL_STYLE = (-16); internal const int WS_DLGFRAME = 0x00400000; internal const int WS_BORDER = 0x00800000; internal const int WS_CAPTION = WS_BORDER | WS_DLGFRAME; // SetWindowPos Flags internal const int SWP_NOSIZE = 0x0001; internal const int SWP_NOMOVE = 0x0002; internal const int SWP_NOZORDER = 0x0004; internal const int SWP_NOACTIVATE = 0x0010; internal const int SWP_FRAMECHANGED = 0x0020; internal const int SWP_NOOWNERZORDER = 0x0200; [DllImport("user32.dll")] static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong); [DllImport("user32.dll", SetLastError = true)] static extern int GetWindowLong(IntPtr hWnd, int nIndex); [DllImport("user32")] internal static extern int SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags); internal static bool IsStyleFlagSet(IntPtr handle, int styleFlag) { return (GetWindowLong(handle, GWL_STYLE) & styleFlag) == styleFlag; } internal static void SetStyleFlag(IntPtr handle, int dwNewLong, bool set) { int style = GetWindowLong(handle, GWL_STYLE); if (set) style |= dwNewLong; else style &= ~dwNewLong; SetWindowLong(handle, GWL_STYLE, style); } } Tag: Using ManualResetEvent within a ContextBoundObject Tag: 113738

    - ConfigurationManager headache Hi there, I am trying to share connection strings amongst multiple console applications in the new 2.0 environment. I see that there is the new ConfigurationManager.ConnectionStrings to handle this, which requires <connectionStrings> .. </connectionStrings> element. However, I don't see any way for console applications to "share" a configuration file. For instance, in the app.config for each app I would like to do the following: <connectionStrings file="path\tosharedconfig.config"> .. </connectionStrings> and then declare the shared stuff in toshareconfig.config. What would be the best solution for this? This works with "appSettings" section, but for some reason not with other sections. I get a warning "the file attribute is not declared" when I try this for the connectionString stuff. Tag: Using ManualResetEvent within a ContextBoundObject Tag: 113724

    - No joy implementing IInternetSecurityManager -- any sample code? Having (laboriously) implemented IInternetSecurityManager in response to WebBrowser.WebBrowserSite.IServiceProvider.QueryService, I now find that (a) only GetSecurityID() and MapUrlToZone() get called, and (b) nothing they return does anything useful. Return bad stuff and the WebBrowser control can no longer navigate anywhere. Return anything valid and what you actually return seems to be totally ignored. In particular, ProcessUrlAction() is not called. It's like the real security is happening somewhere else entirely. So I'm doing something wrong. Any suggestions or sample code appreciated.

For some reason, I tried to create an instance of the ManualResetEvent class
from the constructor of a class that derives from ContextBoundObject (for
automatic synchronization purposes), and after the call to "new
ManualResetEvent(false)" the watch window shows "undefied value" / null for
that instance, altough a call to Debug.Assert(event != null) doesn't assert!
Moreover, when I try to call Set on the event, an exception is thrown (can't
access a disposed object or something like that), even though I didn't
dispose of the event.
Is there a special problem regarding the use of ManualResetEvent in
ContextBoundObjects?
What is the reason for this?
Thanks.
