    - COM+ stream Hello How can I call implement my COM+ service to receive a stream as an argument to one of my methodes. As It is today I can receive strings,bytes and integers but when I try it with a stream I get this error message: "This remoting proxy has no channel sink which means either the server has no registered server channels that are listening, or this application has no suitable client channel to talk to the server. " Which I think is because it can't find a method with this type of structure My COM+ code looks something like this Imports System.IO Public Class WriteFile Inherits System.EnterpriseServices.ServicedComponent -This works fine Public Sub WriteString(ByVal str As String) .... End Sub Public Sub WriteStream(ByVal strm As StreamWriter) -This doesn't work at all ... End Sub End Class I call my COM+ with wf = CreateObject("WriteFile") wf.WriteString("hello world") wf.WStream(myStreamWriter) Any help possible is appreciated Best Regards Magnus Tag: Question: SqlDataReader.GetSqlXXXX vs. SqlDataReader.GetXXXX Tag: 90718

    - How to write plain ascii to a textfile I think I overlook something, but when a write to a text file using a StreamWriter, the file is written as unicode. I'm writing information that is retrieve from nvarchar fields on SQL server. I have a problem with characters like Ã?, Ã?, etc. When looking at the file they seems to be correct, but in some applications the characters are shown as Ã?Å? or Ã?â??. How can I write single byte characters to the file? Just specifying new StreamWriter(FileName, false, Encoding.ASCII) doesn't solve the problem, because the characters are completely wrong. Please advise. Thanks in advance. Tag: Question: SqlDataReader.GetSqlXXXX vs. SqlDataReader.GetXXXX Tag: 90716

    - HTTP req 500 error on SSL When I call the GetRequestStream() method for the site I'm trying to access, I get a long pause followed by an HTTP 500 error (contained in a WebException object) I've tried to mimick the behavior of Explorer exactly to no avail. I believe all my cookie handling and HTTP headers are correct. The site's certificate is from Verisign. The site did just increase the size of the key to 128 bits. Does .NET 1.1's WebRequest class handle that? Or if anyone has any other ideas or suggestions, I'd appreciate a pointer.

    - Problems with public key decryption with RSA I have created an encryption class whose main encryption method encrypts small amounts of bytes (in this case the Key & IV for Rijndael encryption of main data) using .NET's RSA methods. This had all been working fine until I tried using the class within a "Windows Service" application. The application fails on a Decrypt with a "bad key" error in the "Windows Service" but runs fine (with same key & encrypted data) in a normal windows application. The main sections of code from within my class are the following:- I generate my Public / Private keys in a function like this:- // Create RSA Crypto object RSACryptoServiceProvider rsaCSP = new RSACryptoServiceProvider(); // get public & private key xml sPublicKeyXml = rsaCSP.ToXmlString(false); sPrivateKeyXml = rsaCSP.ToXmlString(true); I encrypt like this:- // encrypt symmetric key // Create CSPParameters required object CspParameters cspParam = new CspParameters(); cspParam.Flags = CspProviderFlags.UseDefaultKeyContainer; // encrypt byte[] using asymmetric method RSA RSACryptoServiceProvider rsaCSP = new RSACryptoServiceProvider(cspParam); // load the private key rsaCSP.FromXmlString(sPrivateKeyXml); // encrypt using private key byte[] byteEncrypted = rsaCSP.Encrypt(byteToEncrypt, false); And I decrypt later like this:- // Create CSPParameters required object CspParameters cspParam = new CspParameters(); cspParam.Flags = CspProviderFlags.UseDefaultKeyContainer; // decrypt byte[] using method RSA RSACryptoServiceProvider rsaCSP = new RSACryptoServiceProvider(cspParam); // load the public key rsaCSP.FromXmlString(sPublicKeyXml); // decrypt using public key byte[] byteDecrypt = rsaCSP.Decrypt(byteEncrypted, false); I have tried running the Windows Service as Administrator but got the same "bad key" error. The stack trace here is "System.Security.Cryptography.RSACryptoServiceProvider._DecryptPKWin2KEnh(IntPtr hPubKey, Byte[] rgbKey, Boolean fOAEP)" I also tried :- * changing the CspProviderFlags property to to "UseMachineKeyStore" and the code doesn't work at all, even in the normal windows application running as my user. * Importing key using RSAParameters object - will not work encrypting with private key / decrypting with public key - works other way round. * Various combinations of setting up CspParameters - with KeyContainerName set, Flags = UseMachineKeyStore, to no avail My suspicion is that Key stores are somehow involved but with a deadline looming I now require someone with more knowledge on the subject to help me! Also, can you encrypt using the private key and decrypt using the public key? The above code works like this, but the UseMachineStore solution would only work encrypting with Public Key & decrypting with the Private Key. Really, I need to be able to Encrypt with the Private Key. The customer requirement is to be able to receive encrypted (& signed) data packages where I can also verify they have come from a specific sender. My solution is to encrypt the data with Rijndael encryption, encrypt the Rijndael Key & IV with the RSA Private Key & package that up in one file. To decrypt this use the public key to obtain the Rijndael Key & IV (and know who that this can only have come from someone with the private key) & then finally retrieve the data. Sorry for such a long posting, and there are probably multiple issues here but any help would be hugely appreciated! -- Best Regards, Pike :-) Tag: Question: SqlDataReader.GetSqlXXXX vs. SqlDataReader.GetXXXX Tag: 90708

    - Tell if an object will be local or remote A question. Before I instantiate a type I need to know whether it will be local or remote. Obviously I know the type by a namespace.type string, as I don't have an instance. Now, I can tell a WebService proxy by using reflection to see if it's derived from System.Web.Services.Protocols.SoapHttpClientProtocol, so that's fine. The hard bit comes with MarshalByRef types. I need to distinguish between a MarshalByRef type which is configured for Remoting (eg set up as a well known type) and one which is not. Any ideas? Thanks in advance.

    - RichTextBox Question I am using Framework v1.0 (C#). My question about richtextboxes is: I have been choosing a location in the text box string doing the following: ... textbox.SelectionLength = 0; textbox.SelectionStart = myPos; ... After setting the position I have been inserting text by calling: ... textbox.SelectedText = "Testing"; ... I discovered that the new SelectionStart after using SelectedText is: myPos + 7. 7 being the length of the selected text inserted. This has worked well for me but it has been brought to my attention that this might be a bug in the RichTextBox and I shouldn't rely on this and SelectionStart should really be myPos after using SelectedText. Is this true? I find this to be very useful because if I use SelectedText again say: ... textbox.SelectedText = "NewString"; ... The result would be: "TestingNewString " and not "NewStringTesting" It seems very natural to move the SelectionStart after using SelectedText, am I wrong?

    - Problem with System.Process and quotes/spaces in arguments I wrote a console application that basically consumes arguments and starts other command line apps via System.Process. Let's call it XCompile for now. I wrote a Visual basic add-in that does pretty much the same thing to XCompile. Let's call it MyAddin. XCompile collects information to send to vbc.exe. When it comes across any arguments that are file paths, it wraps them in quotes. For example: [VB.Net psuedocode (from XCompile)] Dim prms As String Dim fil As String Dim files() As String = New String() {"c:\Documents and Settings\...\file with spaces.vb", "temp\NoSpaces.vb"} For Each fil In files prms &= " " prms &= """"c prms &= fil prms &= """"c Next Console.WriteLine("vbc.exe " & Trim(prms)) Dim si As New ProcessStartInfo("vbc.exe", Trim(prms)) si.UseShellExecute = False si.CreateNoWindow = True si.RedirectStandardOutput = True si.RedirectStandardErr = True Dim prc As Process = Process.Start(si) ... This works well. The problem I come across is when I try to use a Process against XCompile in the same fashion. vbvc pretends that all the quotes have disappeared and treats everything with a space in it as a separate argument. [VB.Net psuedocode (from MyAddin)] Dim si As New ProcessStartInfo("XCompile.exe", Trim(prms)) si.UseShellExecute = False si.CreateNoWindow = True si.RedirectStandardOutput = True si.RedirectStandardErr = True Dim prc As Process = Process.Start(si) ... [Output from XCompile] vbc.exe "c:\Documents and Settings\...\file with spaces.vb" "temp\NoSpaces.vb" vbc : Command line error BC2001 : file 'and' could not be found vbc : Command line error BC2001 : file 'Settings\waldo\My' could not be found ... vbc : Command line error BC2008 : no input sources specified So in summary, XCompile works, shelling to vbc by itself, but doesn't work when MyAddin shells to XCompile. Any Ideas why this happens/how to fix it? Thanks in advance. WALDO Tag: Question: SqlDataReader.GetSqlXXXX vs. SqlDataReader.GetXXXX Tag: 90683

    - motivation behind delegates I'm sorry for the newbie question, but I'm a bit confused. I'm reading about Delegats in Jesse Liberty's C# Programming book and, well, I'm confused as to the motivation behind delegates. On the surface, they look exactly like using interfaces in java, so why have another construct to confuse things? I know they work "like function pointers" but the whole reason I went to java was to avoid pointers! And before java, I used VB, so pointers are not something advantageous to me. And I understand delegates are how .net does event driven coding, but why can't interfaces be used to accomplish the samething? Thanks for any advice.

    - Session String value confuses Response.Redirect Overview: I redirect a user to a page to register, then redirect back to orginating page. The registration page is a two part form. On the second post I send the user back to the page they came from. On Page Load I assign a Form value called ReturnURL to a Session value called the same thing. A sample value of ReturnURL would be: ("/whitePapers/paper.aspx?PID=5655") The code is: Session("ReturnURL") = Request("ReturnURL") The user fills in data and submits the form. If the user passes validation they fill out another form. If the user passes validation they are redirected back to the orginal page. Here is the code: Dim sessionReturnURL As String = CType(Session("ReturnURL"), String) Response.Redirect(sessionReturnURL, True) But instead redirecting back to the correct page, the Redirect command appends the sessionReturnURL value under the current directory: http://www.testdomain.com/userReg//whitePapers/paper.aspx?PID=5655 Instead it should be: http://www.testdomain.com/whitePapers/paper.aspx?PID=5655 If I hardcode the value, such as: Response.Redirect("/whitePapers/paper.aspx?PID=5655", True) It works fine, it redirects the user to: http://www.testdomain.com/whitePapers/paper.aspx?PID=5655 Any thoughts?

    - Persistance medium problem. I save and get the ViewState from persistance medium in my application instead of saving it in the hidden field and my program works without problems except in my login screen. In my login screen I have two dropdownlists. The first contains the name "Administrator" and any branch names that the administrator had previously created. The second dropdownlist contains a list of employees that changes whenever the first list is changed. The second dropdown list is not created if the first list has selected Administrator since the Branch is Administrator and the User is Administrator and it would look funny to display a useless dropdownlist. My problem occurs when the Internet is very slow and someone switched from a non administrator to administrator in the first dropdownlist and then clicks the submit button. Since the first submit has processed the change over to eliminate the second dropdownlist, the second submit enters application and when the ViewState is got it does not contain the second list and .Net puts out a message squaking about the missing list. I wouldn't mind if .Net just threw away the second submit. I put javascript code in the form on submit to disable the submit key, but the dropdownlist submit doesn't call the function. I then put javascript in trap the onclick of the dropdown list to disable the submit button but the on click occurs as soon as you click on the dropdown list long before the real submit was issued to my application. I then tried to create the object but make it invisible but that didn't help either. Does anyone know of anyway to solve the problem short of creating the object and disabling it?

    - BinaryFormatter.Deserialize after signing of assembly fails Hello, I have a class which is beeing serialized/deserialized using the BinaryFormatter class. That has been working with no problems until I signed all my assemblies. Now I get a SerializationException when I try to Deserialize the class which has been serialized before the signing. So what is best practice in my situation? Do I have to convert all my saved classes or do I write a SerializationBinder to handle it runtime? If I delete all my data and run fra scratch it works fine until I compile my assembly. Then the assembly gets a new versioand it fails on the version. Why do I get this error now, i did'nt get it before I signed the assembly? Best regards Henrik Skak Pedersen Tag: Question: SqlDataReader.GetSqlXXXX vs. SqlDataReader.GetXXXX Tag: 90645

    - (Color myColor = Color.LightBlue) returns value RGB{0x0}??? Hello, I just started out with Windows.Forms and was going through the MS tutorials. In the tutorial where you can create a non-rectangular shaped window by using your own window painted with some paint utility, I am having some problems with trying to compare the color of the pixel that I retrieve using Bitmap.GetPixel(...) method. My pseudo-code looks like this: **************************************************************************** ****** OnMouse_Click(...) { Color myColor = Bitmap.GetPixel(e.X, e.Y); Color colorToCompare = Color.LightBlue; // At this point I notice that the colorToCompare variable has a value of RGB{0x0}???!!! why? if (myColor == colorToCompare) // then execute logic which never does. } **************************************************************************** ******* I have another question. The reason I am trying to get the color of the pixel is because I want to allow a mousemove event only when the user clicks the mouse on the visible region of my form and not on its transparent background. But I still have the problem that when a user clicks on the transparent background of my window the icons (e.g.) that I see on that position are not chosen? How can I choose the background items on a desktop or if there is another application on the background when a user clicks on the transparent background of my form? -- Regards, Sami [Remove Numbers from e-mail address to use it] Tag: Question: SqlDataReader.GetSqlXXXX vs. SqlDataReader.GetXXXX Tag: 90644

    - Plugin Architecture Problem Hi, [ BTW I'm using C# ] I'm trying to implement a Plugin architecture where I have a single UI framework, and then load dll components into that framework. At the moment I'm constructing the Plugin loading mechanism, I've created a plugin interface ( that the plugin clients must implement ) and a pluginhost interface ( thart the ui framework plugin manager must imlpement ). When the UI framework loads the plugin assembly it checks the types in the assembly to ensure it supports the plugin interface, if it does then it constructs an instance of this type and casts it to the plugin interface type. If I create a source file with these interfaces in and link this file ( i.e. share the file )into each project then I get a CastException - in CreatePluginInstance - when I cast to the plugin interface type. If I implement this interface in a separate dll and then reference this in the framework and the pluginclient, then the cast succeeds. I suppose this works, but I would rather keep the number of dlls to a minimum, and hoped to be able to get away with just sharing the interface source file. Is this possible ??, or do I need to implement it this way ?? regards Rich. CODE: Interface..... namespace PluginInterface { public interface IPlugin { IPluginHost Host{ get;set; } } public interface IPluginHost { bool Register(IPlugin ipi); } } PluginCreation and Cast... Assembly objAssembly = Assembly.LoadFrom(_strPath); foreach (Type iterTypes in objAssembly.GetTypes()) { foreach (Type iterInterfaces in objIterGetAssemblyTypes.GetInterfaces()) { if (iterInterfaces.Equals(typeof(PluginInterface.IPlugin))) { CreatePluginInstance(iterInterfaces); } } } } public void CreatePluginInstance( Type _assemblyType ) { PluginInterface.IPlugin sui_Plugin = (PluginInterface.IPlugin)Activator.CreateInstance(_assemblyType); } Tag: Question: SqlDataReader.GetSqlXXXX vs. SqlDataReader.GetXXXX Tag: 90643

    - Timing Hi everyone, I'm neck deep in ASP.NET and sinking fast ;) Any help much appreciated. I have two user controls on a page that I want to communicate with each other. One control is called RoleList and allows the user to select the type of view they wish to see on the page. The other control(s) - sometimes there may be several - then change the stored proc, query etc they use to extract info from sql. Therefore, I have set up the RoleList to generate an event and coded the other control(s) to listen and recieve it. The problem is timing. I've done some tracing to see what happens and when: 1 aspx.page Begin Init 2 aspx.page End Init 3 aspx.page Begin LoadViewState 4 aspx.page End LoadViewState 5 aspx.page Begin ProcessPostData 6 aspx.page End ProcessPostData 7 Control ID: RoleList - role was previously set in the viewstate: tutor 8 Control ID: StudentList - role was previously set in the viewstate: tutor 9 aspx.page Begin ProcessPostData Second Try 10 aspx.page End ProcessPostData Second Try 11 aspx.page Begin Raise ChangedEvents 12 aspx.page End Raise ChangedEvents 13 aspx.page Begin Raise PostBackEvent 14 Changing role to: Secretary 15 Control ID: RoleList - changed role to: Secretary 16 Control ID: StudentList - changed role to: Secretary 17 aspx.page End Raise PostBackEvent 18 aspx.page Begin PreRender 19 aspx.page End PreRender 20 aspx.page Begin SaveViewState 21 aspx.page End SaveViewState 22 aspx.page Begin Render 23 aspx.page End Render Line 7 and 8 came from the page_load event in each control. Line 14 came from the event being fired and the next two is where the event is caught. But the Load event (which contains the data binding for the list / grids etc) for the response has already happened! Therefore the user must click the role they want to see TWICE!!! I could probably make some public properties in the base page and read/write info from them to get around this. But this will mess up my otherwise quite low coupling and I don't want to.

    - XML schema for a CodeDom Graph Is somebody know an XML Schema to represent a .NET Source Code as an XML file ? More precisely, in CodeDom you can write a source code like this: cns = new CodeNameSpace(...); cns.Imports.Add( new CodeImport(...) ); cns.Imports.Add( new CodeImport(...) ); ctd = new CodeTypeDeclaration(...); ctd.IsClass = true; ctd.Name = "MyClass"; ctd.Members.Add(...); ctd.Statements.Add(...); My wish is to have an XML file like this: <Namespace name="..."> <Imports> <NamespaceImport nameSpace="..."/> <NamespaceImport nameSpace="..."/> </Imports> <Types> <TypeDeclaration name="..." isClass="true"> <Members> ... </Members> <Statements> ... </Statements> </TypeDeclaration> ... </Types> <Namespace> Ultimatly, of course, I would translate my XML to CodeDom and generate my code. I've tried to serialize the CodeDom graph but it's really too verbous. Lionel. Tag: Question: SqlDataReader.GetSqlXXXX vs. SqlDataReader.GetXXXX Tag: 90608

    - Error upon sending request to a web service on Windows 2003 I am facing the following problem I have a windows serivce client sending records frequently to a web service installed on a Windows 2000 Server machine. The connection line between the two machines is 512kbps however only quarter of it is used for these transactions and the average of the records sent is 400K. Recently the machine was upgraded to Windows 2003 Server and i started receiving the following errors: 1. Server was unable to read request. --> There is an error in XML document (1, 1665). --> An unexpected end of file parsing TAG has occurred. Line 609, position 57. 2. The underlying connection was closed: An unexpected error occurred on a receive. 3. The operation has timed-out. Please keep in mind the following: - This error never appeared on the previous 2000 server. - This error doesnt always occur (not for all records), when it does and the client tries to resend the failed records they are sent successfully - I tried to increase the connection timeout value for the web sites enter in IIS and the responseDeadLockInterval in the machine.config file and the masRequestLength in the web.config file however it didnt help - This error also appears when the newly upgraded machine tries to send to other sites Any Solutions?

    - Mobile verses normal aspx? I put a small amount of code to support limited capabilities in my application to support mobile devices. I've used normal aspx (not mobile) and it appears to work very well. I checked it out with the OpenWare 7, Microsoft Mobile Explorer 3.0, and Pocket PC 2002 emulators and everything works very well. I save and get the ViewState from Persistenance media and each of the two pages that I'm producing only transmits about 500 bytes of data so I think the performance is OK. Is there any reason that I should change the code to use the Mobile workspace? Tag: Question: SqlDataReader.GetSqlXXXX vs. SqlDataReader.GetXXXX Tag: 90596

    - Regular expression problems Hello al I am not sure where to post this, so I hope this is correct. We have written a Visual Studio AddIn that relies heavily on regular expressions, which are often executed thousands of times. When running, it works successfully for a while, but the Windows Page File Usage gradually increases, and eventually the application freezes. We have traced the problem to the regular expressions, but the problem does not apply equally to all expressions. For example, the expression "^([\s]*)('|REM( |\t|\v))([\s\S]*)$" does not cause any problems, whereas the expression "^((("(("")|[^"])*")|([\s\S]*?))*)(('([\s\S]*))|$)$" causes a severe memory leak. We always execute the expressions in 'interpreted' mode. Is there a problem with certain expression constructs?

    - PerformanceCounter (CPU load) staggers for 20 seconds When using PerformanceCounter.NextValue to measure CPU load (percentage), it returns quickly on every call but then takes 20 seconds at the 2 minute boundary. After this it again returns quickly. Here's a sample: //********************************** using System.Diagnostics; using System.Threading; PerformanceCounter pc = new PerformanceCounter("Processor", "% Processor Time", "_Total"); pc.NextValue(); // prime (values are relative to last) DateTime now = DateTime.Now; for (int i = 0; i < 240; ++i) { // it staggers at i == 120 int start = Environment.TickCount; decimal load = decimal.Round((decimal) pc.NextValue(), 0); int end = Environment.TickCount; Console.WriteLine("Period: {0}, Load: {1}, Delta: {2}ms", DateTime.Now - now, load, end - start); Thread.Sleep(1000); } //********************************** This code displays the time it takes in milliseconds for each call to PerformanceCounter.NextValue to measure CPU load as a percentage. It typically takes 0ms for the first 119 calls. Then at 01:59 it takes 20 seconds. After that it again returns quickly. I'm seeing this on three different systems (XP Home, XP Pro, Server 2003), and using .NET 1.1 and .NET 2.0 Beta2, both debug and release builds. Has anyone else had problems with this issue? In production code I'm calling PerformanceCounter.NextValue from a separate thread, but it still seems to "freeze" ALL currently running threads of my app - nice 20 second delay :-) It only seems to happen at the 2 minute boundary, after that it doesn't (seem to) happen again.

    - how do you get current username in aspx? I have tried everything I can think of, but nothing is working for me. Just when I read an example and I'm 95% of the way done, I can't actually update the xml file. :< (http://www.devhood.com/Tutorials/tutorial_details.aspx?tutorial_id=96) Very disappointing as the reason I came to aspx was for it's supposed simplicity to JSPs. :< I hope I wasn't wrong. I've tried the following and all I get is this. Exception Details: System.NullReferenceException: Object reference not set to an instance of an object. These are the lines I've tried: testing.Text = Thread.CurrentPrincipal.ToString(); testing.Text = User.ToString(); testing.Text = System.Security.Principal.WindowsIdentity.GetCurrent().Name.ToString(); The aspx compiles so I'm assuming I have all the right imports, what could I be doing wrong?

    - strange memory managment Hi All, This might be something really straight fowward, but I have been debugging my application. I noticed some really unusual memory behaviour, after putting it through a profile, I narrow it down to the property AllowDrop = true. I created some sample code, which simply adds a panel to a tab control 10 times, then removes the control 10 times. If I have AllowDrop=true set the panel is never destoryed in memory. I am just interested in knowing why AllowDrop=true would stop the panel from being destroyed ? Thanks Scott ------------- Sample Code ------------- for(int i=0;i<100;i++){ for(int j=0;j<10;j++){ TabPage page = new TabPage("we"); Panel a = new Panel(); a.AllowDrop = true; page.Controls.Add(a ); this.tabControl1.TabPages.Add(page); } for(int k=0;k<10;k++){ this.tabControl1.TabPages[0].Controls.Clear(); this.tabControl1.TabPages.RemoveAt(0); } } } Tag: Question: SqlDataReader.GetSqlXXXX vs. SqlDataReader.GetXXXX Tag: 90571

    - .Net Remoting TCP or HTTP? Hi, Iâ??m new to .Net Remoting, I am wondering what should I use for my channel, TCP or HTTP. Can someone tell me why I would use one over the other? And in what cases will I use TCP over HTTP and vice versa I am using C# .net. I am behind a firewall; this app will be for a few hundred users over a WAN, internal only. Better performance is what Iâ??m looking for. What Iâ??m trying to build is a middle ware for my windows appâ??s to connect to, and the remoting server will talk to Oracle database and return the data to the client. Andâ?¦ does anyone know about http://www.genuinechannels.com/ what is this? And why would I need this? Tag: Question: SqlDataReader.GetSqlXXXX vs. SqlDataReader.GetXXXX Tag: 90568

Would there be any performance gain to calling SqlDataReader.GetSqlXXXX
instead of SqlDataReader.GetXXXX ?
