    - Creating a remotable object like DCOM Does anyone know if it is possible to return an object from a remoting interface and have it be usable with .NET? I am trying to accomplish what I used to do in DCOM where I would call a function on an interface and it would return a new remote object. I could then call functions on that new object. When I attempt this with .NET it complains that the object has no channel sink. When I looked into the .NET configuration settings, this scenerio didn't seem to fit the 3, SingleCall, SingleInstance, or Client Initiated. The closest one I could think of was Client Initiated but it is the server that creates the object. Any ideas? Is this just not possible with .NET? Thanks. Jayme Tag: \.Net Framework Tag: 122077

    - Threadpool and Sockets Hi All, I don't know in which group my question needs to be posted so here i go: I know that the socket 'begin...' methods uses the threadpool to call the callback function but does that mean that the sockets can't handle more than 25 concurrent 'begin...' methods that complete since the threadpool only has 25 threads to process the completion? Thanks for any insight in this. Greetz, Richard. Tag: \.Net Framework Tag: 122057

    - UserControls in a different directory I have my UserControls in a subdirectory called usercontrols. In the code for one of my UserControls I have the following: Public Property adimage() As String Get Return lnkAdvertisement.ImageUrl End Get Set(ByVal value As String) Response.Write(Me.Page.ResolveClientUrl(value) & "<br/>" & ControlChars.NewLine) lnkAdvertisement.ImageUrl = Me.Page.ResolveClientUrl(value) System.Diagnostics.Debug.Write(Me.Page.ResolveClientUrl(value)) End Set End Property In the Page that uses this UserControl I pass it the value "images/bannerad.jpg". However, when I open the page, the Response.Write() and Debug.Write() lines both output 'images/bannerad.jpg' but the value that gets assigned to lnkAdvertisement.ImageUrl is 'usercontrols/images/bannerad.jpg'. Why is a different value being returned by Me.Page.ResolveClientUrl(value)? My main goal is to make the paths I pass when using the UserControl to be treated as relative to the path of the Page containing the UserControl, not the path of the UserControl. What should I do?

    - Using ASP.NET 2.0's ImageMap Control I am using ASP.NET 2.0's ImageMap Control to create 2 imagemaps, one directly below the other. When I do this a thin blank space appears between them. After several days of frustration I realized that the difference between what the ImageMap Control outputs and the html on the page I was trying to reproduce with ASP.NET 2.0 was the following: Handwritten HTML imagemaps (no whitestrip between them): <table> <tr> <td> <img/><br/> <map> <area/> </map> <img/><br/> <map> <area/> </map> </td> </tr> </table> ASP.NET 2.0 generated HTML using the ImageMap Control (whitestrip appears between the two ImageMaps): <table> <tr> <td> <img/> <map> <area/> </map> <img/> <map> <area/> </map> </td> </tr> </table> In case you didn't see it, the difference is that the handwritten HTML includes a <br/> between the <img/> and <map> tags. However, this is not achievable (at least not using any technique I can think of) using the ASP.NET 2.0 ImageMap Control. What can I do?

    - Serious Socket Programming Problems hello, I just started working with this class at the low level and am having issues. 1) I am instantiating a StreamReader and feeding my NetworkStream to its constructor. the bytes that the StreamReader reads from the server are perfect. however the StreamReader never stops reading / listening! even after the last byte has been received! it just keeps blocking and freezing my client app. does anyone know why this is and what can be done about it? 2) as a workaround to 1), I am parsing the server response to find the last byte. when I do I manually stop the StreamReader. is this really a "workaround" or is it basically what the System.Web.HttpRequest object does behind the scenes? 3) using the process described in 2) my client runs fine - but only in debug mode. in release mode the server response is empty. this seems to be due to bad code. I get my StreamReader to read the NetworkStream object directly after my StreamWriter wrote a HTTP request to it. is there a command I should call in between the two? you know, to delay the read until a server response has been received? long questions, I know. thx for your time Tag: \.Net Framework Tag: 122037

    - Single Sign On / Authentication System? Hi all, I'm looking to implement a single sign on solution for .NET applications. This single sign on solution will need to work against a variety of back- end databases (i.e. SQL (mainly), Active Directory (some), Custom Data Sources (XML, MDB, Custom Web Service, etc). Is there any sample code on implementing a simple single sign on service? The app would need: -Log in Users from the web, desktop clients, custom applications, etc. -Have granular permissions -Be compatible with other web services, desktop apps, and remoting (basically any sort of client/server) -Have the ability to add trusted sites (i.e. servers, viewer consoles, etc) -Work with .NET 1.1 (most of our apps are still 1.1) I was thinking of doing the following: 1. Build a security web service 2. Users would log into a web service to retrieve a token 3. Once a token is retrieve, it is used for all future communications 4. Applications check security against the security service via the Token i.e.: CheckPermission(ByVal Token as GUID, ByVal Permission as String) as Boolean 5. The Web Service would manage a list of valid tokens (time outs, errors, etc) Ecryption would be done primarily on the transport layer - but the token could be encrypted too. What do you guys think about this solution? It's simple... However, how do you handled "trusted" sources? Even better would be for me to find something that was prebuilt :-) Tag: \.Net Framework Tag: 122018

    - Using a TypeConverter instead of Type.GetType(String) Does anyone know of a way (without looking through decompiled ASP.Net code) to convert a String to a Type using the generic TypeConverter stuff? I am writing a deserializer, but I would prefer not to have a custom codepath just for String->Type, but the following code throws a NotSupportedException: TypeDescriptor.GetConverter(typeof(Type)).ConvertFrom("System.String") The problem with the above code is that GetConverter returns the base TypeDescriptor, which always throws an exception on ConvertFrom, but I'm not aware of any gneeric codepaths to do this that don't involve typedescriptors Tag: \.Net Framework Tag: 122015

    - Change password giving errors Hi This is my third question today. Seems like I have run into some problems with AD. I am using the native IADsUser interface to change the password. IADsUser dsUser = DirectoryEntry.NativeObject as IADsUser dsUser.ChangePassword(old, new); The password gets changed. Alls fine till there. The trouble comes when I login again. If I use the old password, the error I get is "The server is not operational", instead of a "Logon failure " message. Instead If i use a random string like "abc" to login, I get a correct error "Logon failure". Can anyone tell me how to fix the former case.

    - Question abt Password Expiry Hi I have to implement password expiry in my application, in the same way as Windows does it. If a user's password at Active Directory is expired or reset, a window is displayed that allows him to change his password. The problem is that if password has expired, then DirectoryEntry.Invoke("ChangePassword", new object[]{old, new}) throws an exception with the message "Logon Failure: Incorrect user id or password." Another complication is that I cannot pass the passwords in cleartext. Do let me know what can be done about this. This is urgent Thanks and regards Vikas Manghani Tag: \.Net Framework Tag: 121991

    - Error decoding ISO character 147 Hi I have a byte-array, in which one of the bytes has the value 149 (hex95) which represents a dot ( ? ). The same character has the unicode value of 8226 (hex 2022) But when I try to decode the byte-array into a string, that character is not converted into the correct value. If I use the following code: byte[] b = new byte[] { 147 }; char[] c = System.Text.Encoding.GetEncoding("ISO-8859-1").GetChars(b); c now contains the character value 147 - which is an illegal unicode value. What am I doing wrong (actually asp.net is doing it wrong as well, because if I enter that character in a text-field, then the wrong value is stored in the database. So the character is not properly decoded when the form is posted to the server) Regards, Pete Tag: \.Net Framework Tag: 121989

    - Interesting problem with SmtpClient in background thread I'm experimenting with the SmtpClient class in c# and I have run into a knotty problem. I'm using the ThreadPool.QueueUserWorkItem to queue a delegate which creates an SmtpClient and attempts to send an email. Basically, If I try and create a new SmtpClient object in a thead managed by the threadpool the application exits without an exception being thrown/caught. However, if I create an SmtpClient in the main program the pooled thread can create the SmtpClient but it then blows up trying to send an email.... Anyone got any ideas..... I'm using the following code public class MailServer { public void QueueMail( string from, string to, string subject, string body ) { MailMessage m = new MailMessage( from, to, subject, body ); ThreadPool.QueueUserWorkItem( new WaitCallback( MailProc ), m ); } static void MailProc( object state ) { SmtpClient clt = null; try { clt = new SmtpClient( "InternalMailServer" ); // <<---- The application blows up here without being caught !! } catch ( Exception e ) { Console.WriteLine( e.Message ); } try { clt.Send( (MailMessage)state ); } catch ( Exception e ) { Console.WriteLine( e.Message ); } } } class Program { static void Main( string[] args ) { // SmtpClient clt = new SmtpClient( "InternalMailServer" ); // <<--- Is I uncomment this line it blows up at the Send() above....

    - Problems when writing a SMTP client and talk with the hotmail Hi, First, I am not trying to talk to hotmail through the SMTP straightly. I am trying to write some codes to send emails through a SMTP server. I wrote a C++ version using pure socket programming and SMTP protocol, a VB version using CDO and a C# version using System.Net.Mail. Now all of them works great with any email account but hotmail. So here is the C# code: MailAddress from = new MailAddress("Z...@CCC.com", "XXX"); MailAddress to = new MailAddress("S...@hotmail.com", "YYY"); MailMessage mail = new MailMessage(from, to); mail.Subject = "Test only, please don't block me"; mail.Body = "Test only, please don't block me"; SmtpClient client = new SmtpClient("xxx.xxx.xxx.xxx"); client.Send(mail); here is the VB Code: Set objMessage = CreateObject("CDO.Message") objMessage.Subject = "Test only, please don't block me" objMessage.Configuration.Fields.Item _ ("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "xxx.xxx.xxx.xxx" objMessage.From = "Z...@CCC.com" objMessage.To = "S...@hotmail.com" objMessage.TextBody = "Test only, please don't block me" objMessage.Send I wouldn't put C++ code here because it's too long. 1. I can use Outlook to send out email (on the same machine where my code runs) and hotmail will receive it with no problem. So I know my SMTP server was not blocked by Hotmail. 2. My SMTP server doesn't require authentication, I know it's bad. But I can't change that. 3. Somebody told me that I would need some strange header to make the hotmail like my email. Therefore I set up a sniffer and get all headers which are used by Outlook. I used all of them in my C++ code but it still doesn't work. Now this hotmail problem drives me crazy and I have wasted 4 hours on it with no clue. Can anybody help me out of here?

    - searching byte arrays and RTFreaders Hi Does anyone know of a .net technique that can quickly find a particular byte value within a byte array and return its position, much as instr does for strings in VB.NET? I'm writing my own custom RTFreader by having my class inherit the .NET System.IO.BinaryReader. My goal is to have a stream reader available in .NET that returns the text portion of an RTF file stream - less any formatting. Being a binary reader, my custom reader loads n-bytes into a byte array. It then loops through this array and only returns qualifying bytes to the calling routine. Some RTF files contain embedded graphics and objects, and these can be made up of hundreds of kilobytes of data. When my custom reader encounters one of these blocks, it spends alot of time looping through the object's bytes just to bypass them. This can cause a significant delay for my reader to return from a call. To speed things up, I thought I could calculate the offset to the end of a block. Each object and graphic in an RTF file is described by a \pict or \object group. These also have tags that describe the object's dimensions. I thought I could take the dimensions, multiply them together and divide that by 255 (because the object data is byte-64 encoded) and multiply by two (because each encoded byte is represented by two hex digits - A5, EF, FF etc) to give me the length of the RTF file's encoded block. This would have worked, except that the width and height dimensions in the RTF file are in twips and not pixels. So, I'm back to looping through the byte array to find the delimiter that marks the end of a block. Is there a facility in .NET that can perform this search at machine language speed and return the location of the found byte? I heard that .NET's regex class might be able to do this, but doesn't that also only work with strings? Andy Tag: \.Net Framework Tag: 121952

    - Is there a way we can send a feature request for Visual Studio? Hi, Is there a way we can send a feature request for Visual Studio? When using 'Refactor-->Encapsulate Field', I'd like to have an option for the references not to be updated anywhere in the project. It would be very useful for me (and probably others too) because I use this feature to generate my properties from my member variables. So I type all my member variables and then take them one by one and encapsulate them... When the project is small it's quick and efficient, but when the project becomes bigger it can take many seconds and sometimes minutes because it searches in all the assemblies of the solution to update the reference to a private variable that is not used anywhere because I just created it. Moreover, it would be nice to take a block of member variables and tell Visual studio to encapsulate them all. It would save a lot of time (and money too). So to reiterate my question : Is there a way (or place) we can send a feature request for Visual Studio? thanks ThunderMusic Tag: \.Net Framework Tag: 121941

The values for Username, Password and Path (and myFilter) are correct and access works fine within other acess software like Jxplorer. But here, unfortunately the call "searcher.FindAll()" throws a System.Runtime.InteropServices.COMException: "0x8007203A: The server is not operational". (Translated English version, we use VS2005 German) I have no idea what to do! Thx for your appreciated help! - Harald Tag: \.Net Framework Tag: 121939

    - Problem with timeout in TransactionScope Hello, I'm porting my application from ServicedComponents to TransactionScope objects. One of the most fun features of new tech is that it allows transaction timeouts more then 10 minutes. My application has many layers and using SqlTransactions is not convinient. As I undestand if TransactionScope is created with TimeSpan.Zero timeout then transaction manager doesn't control transaction time. But actually the transaction is aborted after 10 minutes timeout set in Machine.config. It is true for both SQL 2000 & SQL 2005. If transactions were created explicitly via CommitableTransaction class, this limitation didin't appear ( but only for SQL 2005, SQL 2000 transaction still were aborted ). After explanation of System.Transaction code via Reflector utility I found that TransactionScope always checks timeout via TransactionManager.ValidateTimeout method while CommittableTransaction doesn't. I guess the the problem can be resolved by changing maximalTimeout in machine.config but it is not applicable in the concrete case. I'm wondering is such behavior of TransactionScope designed? Can I rely that CommittableTransaction preserves this behaviour in the next versions or .NET? Thank you for your attention. Vladimir. Tag: \.Net Framework Tag: 121937

    - Intellisense in ASP.NET textbox Hi, Do you know how to implement intellisense behaviour in ASP.NET textbox. Like in destination textbox at http://www.booking.com/ site? It shows cities from all over the world and it works extremely fast. I think it's some sort of partial callback? When I save page i have list only of cities that match first letters. So there is no big XML file. Looking in cache i saw that each string i've entered it shows links example http://www.booking.com/lookup.html?str=new (for new york) Do you know if somebody sells component like this or have any other idea how to do it? Thanks a lot! Tag: \.Net Framework Tag: 121929

    - How to determine if I am in a web or a windows application Hello to all, I use a lib class to handle all my exeption errors ocured in my objects. Since my objects are used in windows applications as well as in web applications, I would like to determine in my lib class if she is serving a web or a windows application.

    - GC problem with large object - .net 1.1 Hello, I have an applications witch works with bitmaps. Such bitmaps are in windows (forms) sizeable. Each time it is neccary to allocate new bitmap with any size-step, because the bitmap is generated. So there is the following situation under .net 1.1 If the window (bitmap) is sized for exampel 10 bitmaps are generated and disposed in 2 seconds. Because the GC does not make garbage collection directly, this costs 10 MB ram instead of 1. If it is exreme, an application which needs realy 10 MB - you see in the taskmanager 50 MB. But this is the first layer of the problem. Now some time later, maybe the GC makes a garbace collection. Now GC-Memory has 10 MB used and 40 MB free. BUT the GC does not give the memory back to the system. (sometimes GC gives a little back to the system, but not all). Means: for a long time you see 50 MB RAM resources used in the tasks manger, what is not the reality, it's only 10 MB. This problem is very hard, because customers see this in the task manager und do not buy the product. So question: Is there any way under dot net 1.1 (.net net 2.0 is absolute impossible in the moment because of many reasons), to reduce the shown used Memory, which is wrong in the taskmanager for this app. Means is it possible to solve the problem when the bitmap is sized that memory is not accumulated, because with each new bitmap the old is disposed. I think there will be no solution under .Net / C#, but would be fine. But also a solution using C++ / unmanged code would be nice. (for the allocation of memory of the bitmaps only). Thank you for any help. Rolf Welskes Tag: \.Net Framework Tag: 121917

    - Install font from ClickOnce application How can I distribute a TrueType font with my Windows Forms application using ClickOnce? Is there a direct/supported way to install via ClickOnce? I tried including the ttf files as resources and copying to the fonts folder on startup. This worked fine, but I can't manage to get them 'registered' properly (in spite of making registry entries and api calls for AddFontResource, CreateScalableFontResource, and SendMessage). These calls appear to work, but I still can't use the font. So, if there is no direct way to install with ClickOnce, any advice on doing the work from C# would be appreciated.

    - Dynamically instance a class I have a setting in my database where the user specifies a tax configuration (e.g. "UK/EU") and I have several tax classes that handle these different configurations. So what is the best way to instance the proper class based on what is in this configuration parameter. I could use a simple switch statement but it seems like there should be a better way.

    - bug with SelectedIndices collection in virtual ListView There seems to be a bug when using a ListView control in virtual mode. If you check the SelectedIndices property of your list view within the SelectedIndexChanged event, and the user Shift-Selects a range of items in the listView, the number of selected indices is always zero. The returned list of selected indices is correct if the user uses the ctrl-select, or just simple selects from the list. This happens when the view property is set to "Details". Of course, you must have the MultiSelect property set to true and the VirtualMode set to true as well. Is there a work-around/fix available for this? Tag: \.Net Framework Tag: 121906

    - reflection for plug in Hi all, I am trying to create a plug-in handler that discovers and enumerates my plug-ins at runtime. I've got it working, but I had to defensively trap and swallow a lot of exceptions. Is there a better way to discover if an executable is a valid assembly? Is there a better way to discover is an assembly has a particular type? Please see the code below that I am using to discover types in a directory and add the valid assemblies to a list.

    - Event handling (C# vs VB6.0) I have the following code in C# to "sink" an event with an event handler. Obj.OnCallEvent +=new CallEventHandler(obj_OnCallEvent); obj_OnCallEvent being the actual method and "obj.OnCallEvent" is the actual event. This events are provided by a 3rd party Dll. I have converted that dll into a type library and used it in VB6.0 However, I'm not sure how to "sink" events in VB6.0! Please advise what would be a compatible statement in VB6.0 for above C# code?

If you have no programs that require it at the moment then no.

However, more programs will require it in the future so you may need it at
some stage. It will install as standard in Vista.
