    - Cannot connect to Remote Debugger After running IIS_REG for .NET 2005 Framework version 2, I enabled the Remote Debugging Monitor (RDM) I added our development group to the local policies to allow the RDM to run as a service instead of a local application like the MSDN site says. When the person next to me click the start button for their 2005 ASP application, everything is fine. If I click start, then I get the message that the RDM is unable to connect to my machine. After visiting: http://msdn2.microsoft.com/en-us/library/ms164725.aspx Im still not clear as to why it cannot connect to my PC. I am an administrator on both my local PC and the server that house our .NET projects. The person that has no problem connecting is also an administrator. There appears to be no difference in our local PCs users or groups, yet it still cannot connect to my PC. Please help what am I missing here???????????????????????

    - DirectorySearcher.Filter doesnt seem to work Im creating a app that will go through all the OU's and look for a certain user by username. In doing some testing I noticed that its not filtering everything out exept for user ObjectClass. It seems to be pulling computers as well. Not sure why this is happening but need to limit it to just user objects. Here is the code I have. Imports System Imports System.DirectoryServices Namespace ActiveDirectorySearch Public Class ADSearch Shared Sub main(ByVal strUserName As String) Dim DSESearcher As New DirectorySearcher() DSESearcher.SearchScope = SearchScope.Subtree DSESearcher.Filter = "(objectClass=user)" Dim objResults As SearchResult For Each objResults In DSESearcher.FindAll() Console.WriteLine(objResults.GetDirectoryEntry.Properties("samaccountname").Value & "...." & objResults.GetDirectoryEntry.Path) Next End Sub End Class End Namespace Tag: About DataGridView control's issue Tag: 122127

    - Using ConfigurationManager/ConfigurationSettings to retrieve settings returns null values Hello, Using VS2005, I have a Windows Forms app that uses the default Settings.settings file. When the app is built, the properly-named app.settings file is built into the output directory, and it contains the correct application-level settings. Controls in the app that are bound to settings in the app.config display the correct values. When values are changed by hand in the app.settings file these new values are correctly displayed when the app is run. In code, the following calls correctly retrieve settings values: global::<namespace>.Properties.Settings[<settingname>] Properties.Settings[<settingname>] Properties.Settings.<settingname> However, the following functions always return null values: ConfigurationManager.AppSettings[<settingname>] ConfigurationSettings.AppSettings[<settingname>] ConfigurationManager.OpenExeConfiguration(Assembly.GetEntryAssembly().Location).AppSettings.Settings[<settingname>] ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None).AppSettings.Settings[<settingname>] ExeConfigurationFileMap efm = new ExeConfigurationFileMap(); efm.ConfigFileName = Assembly.GetEntryAssembly().Location + ".config"; ConfigurationManager.OpenMappedExeConfiguration(efm, ConfigurationUserLevel.None).AppSettings.Settings[<settingname>] All returned Configuration objects have the correct filepath and HasFile==true. I can use the Properties.Settings syntax when I'm in the right class, but I need to access these settings from a satellite assembly and don't want to pass around references if I don't have to. Can anyone tell me what I'm doing wrong, or why these function calls can't manage to find my settings? Keith Tag: About DataGridView control's issue Tag: 122122

    - too many using (imports in vb)... does it hit on performance or memory usage? Hi, I want to know if having to many using (imports in VB) statements at the top of a class or page can hit on the performance of the application or on the memory usage of the application.

    - unwanted network printer switching We have a small network in our office running Windows 2000 Server. All machines are running XP-Pro with all the updates. One person has her default printer set to the printer on her desk. Occasionally, when she prints a document it goes to another printer on the network. There is no obvious pattern as to when this happens. When she looks at her printer setup page her default printer is now the one where the document went to, i.e. not the one on her desk. How can we stop this? Dan Tag: About DataGridView control's issue Tag: 122096

    - 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.

    - 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: About DataGridView control's issue 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: About DataGridView control's issue Tag: 122018

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: About DataGridView control's issue Tag: 122015

    - 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.

    - 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: About DataGridView control's issue 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.... MailServer m = new MailServer(); m.QueueMail( "from@fromcom", "to@to.com", "This is a queued test message", "hello world again" ); } } Tag: About DataGridView control's issue Tag: 121984

    - 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? Thanks Ou P.S It's a little bit ironic to see that MS' product doesn't work well on its own product. Tag: About DataGridView control's issue Tag: 121968

    - Reflection and Generics I am writing a function that replaces tokens in a string with property values of a given object. from each token I get a property name and using reflection, I get the value of the property. Some properties are generic lists, I can tell what is the type of the generic in the list (PropertyValue.GetType.GetGenericArguments) How can I cast the value returned by the InvokeMember call to the right generic type? in this sample "ClaimManagerItem" is a base class, GenericType will always be of class inheriting from the base class PropertyValue = SourceType.InvokeMember(PropertyName, Flags, Nothing, Source, Nothing) If PropertyValue.GetType.GetGenericArguments.Length <> 0 Then 'Generic Dim GenericType As Type = PropertyValue.GetType.GetGenericArguments(0) For Each CMItem As ClaimManagerItem In DirectCast(PropertyValue, GenericType(of ??? ) ... ...

    - RSA 1024 Bit Decryption with *.Pem Key Hi guys, We have created a key pair (privKey.pem, pubKey.pem) with OpenSSL as our partner requested (they use this format). They encrypted a string with our public key and then base64 encoded the string. We want to use Visual Studio.net 2003 to base64 decode the string, and then decrypt the string with the private key (*.pem format). It seems that VS.Net uses xml keys for this natively. Is there a way to work with the OpenSSL *.Pem key files with the RSACryptoProvider? Any advice/help/guidance would be appreciated. Thanks, Ron Tag: About DataGridView control's issue Tag: 121960

    - 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: About DataGridView control's issue Tag: 121952
