    - ClientScript.RegisterClientScriptBlock in ASP.NET 2.0 I am working on converting my code from ASP.NET 1.1 to ASP.NET 2.0. In ASP.NET 1.1 the RegisterClientScriptBlock method was just a key and script (2 Strings), but in ASP.NET the ClientScript.RegisterClientScriptBlock also includes a parameter called 'type' which is of Type. This sounds like it is supposed to specify whether the script is JavaScript, VBScript, JScript, ECMAScript, etc., but I what am I supposed to enter here (I have not heard of a value of Type that would specify this)? (I always use JavaScript for my client-side scripts) Thanks. -- Nathan Sokalski njsokalski@hotmail.com http://www.nathansokalski.com/ Tag: disabling sound card Tag: 118627

    - Blob reading problems Hi I'm trying to read RTF and Word files from blob columns in SQL Server, but the files can't be opened in Word when i retreive them. They seem to contain garbage... What am I doing wrong? This is some of the code used to get the files: FileStream fileStream = new FileStream(filename, FileMode.Create, FileAccess.Write); BinaryWriter binaryWriter = new BinaryWriter(fileStream); long totalBytes = sqlDataReader.GetBytes(blobColumn, 0, null, 0, int.MaxValue); byte[] outbyte = new byte[totalBytes]; sqlDataReader.GetBytes(blobColumn, 0, outbyte, 0, (int)totalBytes); binaryWriter.Write(outbyte, 0, (int)totalBytes); binaryWriter.Flush(); binaryWriter.Close(); fileStream.Close(); Tag: disabling sound card Tag: 118625

    - debug custom assemblies Hi, My application provides a feature to load custom assemblies. The application is build in release mode (/optimize). This is .NET 2.0. As a user wants to debug his custom assembly be e.g. forcing a debugger break ("Debugger.Break()"), he experiences that he can not inspect the value of the public properties of any class, since they are optimized away: "Cannot evaluate expression because the code of the current method is optimized." This is true even as the compiled assembly is built in debug mode using "/optimize-". I found something in docs, saying that the /optimize settings of the calling assembly - which is my app built in release mode - take precedence. What can be done to make the custom assembly fully debuggable? Thanks in advance. Dierk Droth Tag: disabling sound card Tag: 118619

    - Publishing An ASP.NET Website With Visual Studio .NET 2005 I recently upgraded to from Visual Studio .NET 2003 to Visual Studio .NET 2005. In Visual Studio .NET 2003 when I would select 'Build' it would add a *.dll with the name of the Project to a /bin/ folder in the same directory as the source code. However, in Visual Studio .NET 2005 when I selected 'Publish Web Site' and selected a target location to place it in, it placed the following files in it: All *.aspx files All *.html files All *.css files All *.js files All *.mdb files web.config PrecompiledApp.config images/*.* bin/App_Code.compiled bin/App_Code.dll bin/App_Web_p5v6buoq.dll bin/App_Web_xx-bm_x8.dll This is fine, except I don't know what to do with the following of these files: PrecompiledApp.config bin/App_Code.compiled bin/App_Code.dll bin/App_Web_p5v6buoq.dll bin/App_Web_xx-bm_x8.dll What are each of these files, what do I do with each of them, and why are there 3 *.dll files now, unlike just one like there was in Visual Studio .NET 2003?

    - IOC concepts Hi. I'm thinking about fairly common problem - service binding. I'd like to have access to common services from all over the code without any special attenction. The .NET's service provider architecture achieves this, but has one drawback - given service is configured once for whole system; my analysis shows that i have to bind services, depending on who is requesting. Below there are four solutions, but none of them satisfies me. All of them assume there is "wise" class called ServiceManager which is able to resolve references and handle the context tracking - probably solution used in Log4Net (loggers defined by name and assigned after caller type name analysis) would be sufficient for my purposes. The problem i'm trying to aim here is the "client side" code. So - let's start with Log4Net approach: /* Idea 0 */ public class ServiceByDirectReferenceBinding { public void do() { LogService.GetLogService(this).Log("doing"); DaoService.GetDaoService(this).TestConnection(); } } #region Static service access wrappers... public class LogService { static ILogService GetLogService(object caller) { return ServiceManager.Get(typeof(ILogService), caller) } } public class DaoService { static IDaoService GetDaoService(object caller) { return ServiceManager.Get(typeof(IDaoService), caller) } } //for real life sample - see Log4Net api... //the static service access methods could have been //avoided, but then client code would require //direct service manager calls and type casts upon //every service method call (what binds client //code directly to service manager - and it would be //good to avoid it...) #endregion /* Idea 1 */ public class ServiceByProperties { #region "This could have been generated" private ILogService logger; private ILogService Logger { get { if(logger!=null) return logger; logger=ServiceManager.Get(typeof(ILogService),this); return logger; } } private IDaoService dao; private IDaoService Dao { get { if(dao!=null) return dao; dao=ServiceManager.Get(typeof(IDaoService),this); return dao; } } #endregion public void do() { //and such "client" api is my target :) Logger.Log("doing..."); Dao.TestConntection(); } } /* Idea 2 */ public class ServiceByInjection { private ILogService Logger; private IDaoService Dao; public ServiceByInjection() { ServiceManager.InjectDependencies(this); //or ensure dependencies are injected //by caller, what is easy for services resolved using //service manager (dependencies injected during //ServiceManager.Get()), but not possible for //plain objects created with usual o=new O() } public void do() { Logger.Log("doing..."); Dao.TestConntection(); } } /* Idea 3 */ public class ServiceByMagic { public void do() { Logger.Log("doing..."); Dao.TestConntection(); } } #region This could have been generated public static class Logger: implements statically interface ILogService { static void Log(string message) { ServiceManager.Get(typeof(ILogService), FindOutWhoCalledMe()).Log(message); } ... } public static class Dao: implements statically interface IDaoService { static bool TestConntection() { return ServiceManager.Get(typeof(IDaoService), FindOutWhoCalledMe()); } ... } #endregion At the moment it seems Idea 3 would be really nice if it's possible to generate wrapper classes and implement FindOutWhoCalledMe() somehow... Any ideas how to start? (reflection.emit? compiler services?) -- greetings marcin Tag: disabling sound card Tag: 118606

    - File performance I am opening a number of large files (100 to 900 Mhz) to extact some header information (500 bytes). watching the memory usage on the task bar when ever the call Filestream fs = File.Open(filename, Filemode.Open) is called, the memory usage jumps way beyond that expected (89 Mhz file usage jumps by 400 M). I then use a few fs.Read calls to extract the info required then call fs.Close and fs.dispose. The memory usage still remains high which can cause problems as if the number of files checked is large the machine complains about the amount of memory not available. Is thier a way to reduce the amount of memory required, surely then amount of memeory required should be a few bytes as I only require a pointer to the file. With thanks.

    - How do I do this Looking at the ".resx" files produced by the Windows forms designer, I see nodes like this: <data name="MyRadioBtn.Size" type="System.Drawing.Size, System.Drawing"> <value>94, 21</value> If you then read the "94, 21" back into your code as a string (exactly as seen), how do you then deserialize it so it can be converted back into a "System.Drawing.Size" object (i.e.,there's no "System.Drawing.Size" constructor that takes this string as an argument but in any case, I assume the correct way is to reverse the process that created this string in the first place).

When generating a public key, you get <Modulus> and <Exponent> values. What parts do you need to share with someone. Also, what is the correct format for these values? 3) If someone gives me their public key, how do I format it for XML? Eg. do I need to convert the key in any way or just add a new XML file and put in the key values? Thanks Tag: disabling sound card Tag: 118593

    - Escaping backslashes in XPath (C#) I have an XML file which have nodes that contain filepaths, e.g.<path>c:\SomeDirectory\SomeFile.txt</path> I'm using an XmlDocument and XPath query to try and find a node XmlDocument doc = new XmlDocument(); doc.LoadXml(File.ReadAllText(xmlFilePath)); string somePath = @"c:\SomeDirectory\SomeFile.txt"; string query = "node1/node2[Path='" + somePath + "']"; XmlNodeList nodes = doc.SelectNodes(query); The problem is, query becomes "node1/node2[Path='c:\\SomeDirectory\\SomeFile.txt']" (Note the double quotes due to the escaping of the backslashes). Obviously this doesn't match the XML node in question. How do I work around this? (I don't want to use double backslashes in the XML file.) Tag: disabling sound card Tag: 118581

    - .Net framework and VB Hi, I have recently started coding and designing the ,.NET based system using different technology involved in .NET and well from the subject line of this post, it is obvious that I am coming from a VB background. I have many years of expirance in designing distributed system based on VB, C++ and SQL Server but when I have tried .NET it is a complete new exerince for me and I am not hesitant in saying this is a damm cool stuff from MS. Now in this regards, I got a question but I am really not sure what is the case in .NET. In earlier days, when I used to design classes based on limited VB object based model, we used to create 2 different callses for one business component. One class which is used for all database read operation and another for database write, update and delete opeation. Now, why we were doing this so because of the locking in database via VB programs. if all database select operation id seperated from database write operation it palces less locks and almost comes out immediatly by removing database locks (Offcorse when all the VB dlls are regirsted in COM+). Now I wanted know is this still applicable in .NET. For example, if I want to write a Cusomter business component, do I still have to seperate out the select and updates in seperate classes. In earlier days, I used to designed a dll with following classes. CustomerRead (Main class to read, exposed to world) CustomerWrite (Main class to write, exposed to world) CustomerSingleSelect - a calss which gets data from customer based on primary key and always return me a sigle row CustomerMultiSelect - a class which gets the data from customer where select operation is not based on its primay key. CustomerModify - a class to modify customer. Belive me this approch was much faster then everything in one class. But this was the case in VB time. Does this still a case in .NET?

There are several questions I have about the code differences between them (I use VB.NET for as my language of choice): 1. 2003 used "Public Class classname" and 2005 uses "Partial Class classname". What, if any, difference is there between these? 2. The following things are included in the #Region " Web Form Designer Generated Code " part of 2003's code, and are not included automatically in 2005: <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent() End Sub Control declarations, such as: Protected WithEvents lblWebsite As System.Web.UI.WebControls.Label Private designerPlaceholderDeclaration As System.Object Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init InitializeComponent() End Sub Do I need to include any of these manually or anything else that serves their purpose? 3. In 2003 the Page Events use clauses such as Handles MyBase.Load while 2005 uses Handles Me.Load. I am assuming that these will work the same? I am sure that I will run into the other differences between the two, but these are some of the important ones for me right now.

    - Now I need to do this without breaking ASP.Net I've been struggling for two weeks now to duplicate a VB6 ActiveX control in VB.Net, and also improve it's functionality. The control is used to collect the user's fingerprint and compare it to a stored copy on the server, and if the match is successful fill some hidden fields with values and call a form submit. We wanted to use web services rather than direct SQL connections as we do now, and to also have the web service URL set dynamically. We built the project as a Windows Control (DLL) class with COM Class and COM Visible set to True. We were able to get the control to load in IE, but due to the need to interface with the local USB fingerprint device we had to list the web site as Trusted and elevate the Trusted Zone to perform no security checks (Problem #1). The class required a couple of DLL files to function properly, and as expected we were able to put them in the same folder as the class DLL file and they were downloaded automatically. The problem was the App.Config file, it never would download. (Problem #2) We recently figured out that apparently a DLL can't make use of App.Config, but the calling app can. This explained seeing the client attempt to download iexplore.exe.config in the web logs. To make matters worse, it wasn't attempting to download the file from the location of the class DLL, but rather from the root of the web site and from /bin folder. (Problem #3) So we renamed the App.Config file and placed it in the root. It still would not download, this time with 403 Errors which we determined were the ASP.Net interpreter trying to process the file rather than allow direct access. (Problem #4) We decided to remove the parsing of .config files from the configuration of the root web app, which finally allowed everything to execute properly. But now, if we had any web.config files in the root app, they would be open to being freely downloaded, and might not even work at all (Problem #5) I just know there has to be a better way to do this. I cannot believe that it's this difficult with .Net to duplicate and improve on the functionality we had using VB6. Perhaps someone with experience in things such as this will step forward and point us in another direction. Thanks, Patrick Bates Tag: disabling sound card Tag: 118516

    - RSACryptoServiceProvider.VerifyData Hangs I have found that RSACryptoServiceProvider.VerifyData sometimes hangs for several (typically 6 or more) seconds.

    - Up/down value conversions Greetings, We are using an up/down control to facilitate numeric data entry, however, we are noticing issues converting from the up/down value (apparently a Decimal) to the units we are working with (Double) and vice versa.

    - Display text in different colors in a textbox using WndProc Hi All, I need to have a text box that displays text in different colors. I tired overriding WndProc but I still couldn't. Below is the code snippet I'm using. Would appreciate if someone could help me out with this (wolud appreciate if the solution is done using WndProc) const int WM_PAINT = 0xF; [DllImport("user32.dll")] public static extern IntPtr GetWindowDC(IntPtr hWnd); [DllImport("user32.dll")] public static extern int ReleaseDC(IntPtr hWnd, IntPtr hDC); protected override void WndProc(ref System.Windows.Forms.Message m) { base.WndProc(ref m); switch (m.Msg) { case WM_PAINT: IntPtr hDC = GetWindowDC(m.HWnd); Graphics graph = Graphics.FromHdc(hDC); graph.DrawString(this.Text, this.Font, new SolidBrush(Color.Red), 1.6F, 2.5F); graph.Dispose(); ReleaseDC(m.HWnd, hDC); m.Result = IntPtr.Zero; break; } } Thanks!

    - MS Unit test and CruiseControl.Net integration Hi All, We are currently running continous integration using a server running cruise control.net. This server does not have VS2005 installed on it, only the .Net framework. Previously, we have been using Nunit to write our tests but I thought I would give the integrated MS unit test a go and submitted these test to source control.... Which has broken the build because the Microsoft.VisualStudio.QualityTools.UnitTestFramework dll is not present on the server.... So my question is, can you run MS unit tests as part of an automated build process without having a full install of VS2005 on the integration server? Thanks in advance!

    - .NET UpDown KeyPress Beep Greetings, We are handling the KeyPress event in an UpDown control, which determines if Enter or Escape has been pressed, then closes the dialog with either a DialogResult.OK or DialogResult.Cancel, respectively. We seem to be having a beep occur when this happens, at some point after the event handler is through processing. Not sure quite why this is. Any ideas to inspire us in the right direction?

    - Maximum Characters in Stringbuilder? Hello, I'm using a Stringbuilder to building dynamic HTML, and I was wondering how long it can get before it gives up. I won't know the length of the HTML until it's finished building it. I've read a few articles that suggest setting an initial size when you instantiate it, but will that work even if I don't know how much I'm storing? Any help would be appreciated. Thanks!

    - binding to an unsigned assembly outside the appbase ...is this possible? Can you perchance provide an entry in the config file which would allow such behaviour? I think it should be possible at least on the local machine, you can always copy those unsigned assemblies to a subfolder of your app, so it's not like it's a security feat.

    - Creation of HTTP streaming server using .NET HttpListener Hi, I'm posting this in the general .NET forum because I'm not sure into which subcategory this belongs. I've searched through the newsgroups and found many posts related to audio/video streaming mainly using the Windows Media Services. I'm trying to create an HTTP server in C# (using HttpListener, HttpListenerRequest and HttpListenerResponse) where I can stream videos to potentially any media player that can stream via HTTP (WMP, RealMedia, VLC). The reason why I want to do it this way is because I already have a stream in the ASF format, so I just need to split it in packets and send it out. So far I haven't been able to get a stream to work correctly primarily because I wasn't able to setup the response parameters to what they'd need to be. It seems that I either have to set the 'Transfer-encoding' to 'chunked' or specify the content length. Has anyone done anything similar to this with these classes or does anyone know if that's possible at all? Thanks. Tag: disabling sound card Tag: 118469

    - Update Profile of Created User I've created my own version of the CreateUserWizard control that gathers up all the information I need when a user requests an account. Once all the data is gathered and validated, the FinishButtonClick property calls a method that does the following: 1. Creates the user account: Membership.CreateUser(myName, myPwd, myName, myQue, myAns, true, out createStatus); (I'm using the email address (myName) as the username, which is why it shows up twice) 2. I then want to update the newly created user's profile with the information that was entered: Profile.UserInfo.UserEmail = UserName.Text; Profile.UserInfo.FirstName = FirstName.Text; Profile.UserInfo.MiddleInitial = MI.Text; ..etc. I do not want these profiles created for anonymous users, so my web.config file looks like this: <anonymousIdentification enabled="false" /> <properties> <group name="UserInfo"> <add name="FirstName" type="System.String" allowAnonymous="false" /> <add name="MiddleInitial" type="System.String" allowAnonymous="false" /> <add name="LastName" type="System.String" allowAnonymous="false" /> ..etc. </group> </properties> I have tried several methods to ensure that the newly created user is logged in, by using the Membership.ValidateUser(), the FormsAuthentications.AuthorizeUser(), and none of them have worked. However the MembershipUser object returned by the CreateUser method shows that that user is currently OnLine. I always end up with the following error message the moment I try to call the SetPropertyValue of the first profile property: "This property cannot be set for anonymous users." Note that I do not want the user to be able to log in yet until their account has been approved, so once the profile info is created I would have to log them out and set their account to Inactive.

Unless there's something about this in managed DirectX, there isn't any
managed object that will allow you to do this. You'll have to find an
unmanaged method of doing this, and use platform invoke to execute the
method. A good starting point is pinvoke.net.

However, if I ran a program that disabled my sound card without my explicit
permission (and good reason) I'd be pretty ticked off at the jerks who wrote
it. Can I ask why you believe you need to do this?
