 - Question about generic IEnumerable Visual Studio won't give me the "implement interface option" when I do this: public class Dictionary<K,T> : IEnumerable<KeyValuePair<K,T>> but it does when I do this: public class Dictionary<K,T> : IEnumerable<K> and what is the difference between the right-click menu choices "Implement Interface" and "Implement Interface Explicitly"? They both appear to generate the same code? Tag: VSTS Performance Explorer issues Tag: 113998

 - Serious bug in .NET framework 2.0 - IShellLink interface crashes This is a multi-part message in MIME format. --------------080507040709070501060408 Content-Type: text/plain; charset=ISO-8859-15 Content-Transfer-Encoding: 8bit *Hello* I wrote an application which runs perfect under .NET framework 1.1. I was very disappointed, that a LOT of things do NOT work on *Framework 2.0*. This framework is NOT downward compatible. For one of the problems I could not yet find a solution or not even an explanation: My project loads a managed C++ DLL which uses the *IShellLink* interface to resolve shortcuts. The function ResolveShortCut() (see below) is called from the main C# program in a thread loop to resolve all links found on the desktop. This works perfect on .NET framework 1.1 But on Framework 2.0 the behaviour is really strange and always different: 1.) Sometimes the function ResolveShortCut() (see below) works 10 or even 100 times without problems. 2.) Then suddenly it happens that *CoInitialize(0)* fails. 3.) Another time *CoCreateInstance(CLSID_ShellLink, ...)* fails. 4.) The next time at the point *i_ShLink->GetPath(...)* a crash appears which cannot even be caught by a try catch block (neither in managed C++ nor in the calling C# code !!) _*Types of Crashes*_: 1.) Sometimes the whole application crashes without any error message. (the application silently disappears from the screen) 2.) Another time I get a window which asks me to send the crash information to Microsoft 3.) Another time I get an error telling me something about "out of memory".

It is impossible to completely UNINSTALL framework 2.0 !

 - migration from asp: better client or server-side code? Hi, I made an application in classic asp (reservation of books and video stuffs for students) and want to migrate to asp.net. The user has to chose a date, then pushung on a submit button. The whole day is then displayed in cels of a table. The user has then to click in a cel representing a hour of the day and an object (book ..), and finally click on the submit button to insert that reservation in the database. My problem is: there is a lot of javascript client-side code. All onclick events are executed on client-side. Have i to change this into server-side code or i can still use that client-side code? Is it true that the filosophy of asp.net is: maximum server-side script and minimum client-side? If so, is there no danger to overload the server, instead of sharing the execution of the application between client and server? Thanks for help Ben Tag: VSTS Performance Explorer issues Tag: 113982

 - Dynamic Method's Body and IL ??? Hi I am using C# 2.0. I need to use the MethodBuilder.CreateMethodBody that takes byte[] as the input parameter taking the IL codes as byte array. I feed this input from MethodBody.GetILAsByteArray. But when the method created dynamically via MethodBuilder.CreateMethodBody is invoked by TypeBuilder.Invoke, it throws exception [inner exception] "Bad Method Token". If the body of the method [which is requested as IL by the MethodBody.GetILAsByteArray] is empty, then the method executes successfully. Is there any special that has to be done with the byte [] from MethodBody.GetILAsByteArray before giving it as input to the MethodBuilder.CreateBody. I could not find enough information even on the MSDN documentation about this. Your help is appreciated. Thanks Vivek Ragunathan Tag: VSTS Performance Explorer issues Tag: 113978

 - Update function created using Web Matrix Code Wizard fails Hello, I am using the Web Matrix Code Wizard's Update feature. I have a very simple user interface that has two textboxes. One is for a Name and the other is for a Description. I also have a dropdown listbox. I am working with the Northwind database attempting to update the Category table. The dropdown listbox is populated with the categoryID and the two textboxes are for the CategoryName and CategoryDescription fields. I have data successfully populating the textboxes and when I select a new categoryID in the dropdown listbox, the data in the textboxes changes accordingly. My problem is updating the database. Below I have a function that was created using the Update Code Wizard. I also have an event subroutine that fires when I click the Save button which calls the MyUpdateMethod function. Not sure why, but when I make changes to the textboxes and click save, the changes do not stick. I select a different ID and then select the ID that I made changes to but the changes are not there. I am running on my localhost Web Matrix Server. To view a MSDN walkthrough of a similar exercise go to http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbwlkwalkthroughupdatingdatausingdatabaseupdatequeryinwebforms.asp Any ideas would be greatly appreciated.

 - Uploading Files I'm trying to figure out a way for a user to be able to select a file name (on their local hard drive) and upload it to a web server.

I would also want to upload c:\myfile.gif and c:\myfile.jpg. I would assume this is impossible to do, for security reasons....unless I wrote and activex component to do it...?

 - Updating access database Thanks in advance for any help. I am using code that is directly from David Sceppa's book from MS Press titled "ADO.NET". I have walked completely though the code and I find values are what they should be until I reach the following subroutine. Private Sub SubmitChangesByHand() Dim cmdUpdate As System.Data.OleDb.OleDbCommand = CreateUpdateCommand() Dim row As System.Data.DataRow Dim intRowsAffected As Integer Dim dvrs As System.Data.DataViewRowState dvrs = System.Data.DataViewRowState.ModifiedCurrent Or System.Data.DataViewRowState.Deleted Or System.Data.DataViewRowState.Added For Each row In tbl.Select ("", "", dvrs) msgbox("in the for loop") intRowsAffected = SubmitUpdate(row, cmdUpdate) msgbox(intRowsAffected) if intRowsAffected = 1 then row.AcceptChanges() else row.RowError = "Update attempt failed" End If Next row End Sub For some reason I am not getting inside the For loop. Only thing I can see is that the DataViewRowState is returning a value of 28 which should be 16 (for updating a database). I invoke the function by a button click event elsewhere in the code. Other than that, the table has records in it which is declared elsewhere as: Dim tbl As New System.Data.DataTable("categories") I am using the Northwind database in my trial efforts.

 - CounterSample & nextSample I need to produce the 5 minute average CPU utilization for a system (the average utilization over a 5 minute period). I found the below article that seems to do a reasonably complete job of explaining the differences between raw, calculated and sampled performance data. http://msdn2.microsoft.com/en-us/library/xb29hack.aspx CPU utilization is of type Timer100NsInverse. So here is my question: to get the most accurate 5 minute average of CPU utilization, should I be taking a sample at 0 minutes, another sample at 5 minutes, and then calculate the results (see below code for an example)? Advice would be appreciated. Thanks in advance.

 - Equivalent to VCL's DataModule In Borland's VCL ( Visual Component Library ), one can use a DataModule into which one can drop non-visual components from the RAD designer. The DataModule is a design-time visual container for non-GUI components, which is never seen visually at run-time as a GUI control. An application or Dll can have any number of datamodules in it, each with its own name. One can also manually add any non-GUI data to any particular DataModule. For an application at run-time, datamodule instances for each visual datamodule are automatically created just like forms, while for a Dll at run-time it is the programmer's responsibility to create datamodule instances for each visual datamodule created at design time. I have found the ability to use datamodules as visual containers to non-GUI components in an application or Dll to be very useful. Admittedly a datamodule is nothing more than a class which contains instances of non-GUI components and possibly other non-GUI fields, but I like the ability to manipulate it at design time, and as a means of separating the data portion of an application or Dll from the GUI portion. Does .NET have any equivalent to this idea, so that non-visual components can be created at design time without having to drop such a component on a Windows or Web form. ?

 - UTF8 to UTF16 ? I'm somewhat confused about Unicode but up until now I havent really seen much issues with using it up until recently. We recently started using an SMS gateway that requires a unicode message to be sent as a hexadecimal string where each byte code has been replaced with their hexadecimal value, for example: 043104AF0442044D044... This string according to their documentation must be in UTF-16 before conversion to the hexadecimal form, we however are using UTF-8 on our website and all the texts are entered as UTF-8. When I try to send a unicode formatted message using content from our website it shows some characters correctly but not all of them, I cannot see another reason for this than the fact that we are using UTF-8 and they require it to be in UTF-16. Now to the questions: 1. How do I convert between UTF-8 and UTF-16 ? I was looking at the Decoder, Encoder classes but it doesn't really provide a direct way to convert between encodings that I could see. 2. Since all strings are actually UTF-16 in .NET does this mean that the conversion already has been made or does it mean it is actually storing UTF-8 encoded bytes into a UTF-16 string ? Thank you PL.

 - Additional component to web service I post here is because there is no one answer my question(10 days ago) in "web service" news group. I am going to implement a program on the web service side. The program will work with the web services so that it can do some check on the data before invoking any web method. The program will do some general checks, and does not know exactly what kinds of web methods behind. I think I could write a dll, then let the web services to call this dll first before the web methods are invoked. But I do not how to do exactly. Is there any way to integrate the program into the web services? Please give me a guide in details. Thanks. Tag: VSTS Performance Explorer issues Tag: 113944

 - how to interpret Number property in System.Data.SqlClient.SqlError Environment: .NET 1.1, SQL 2000, VS.NET 2003. We have some logic in an application to perform some recovery operation on the client side based on the SQL error code returned from System.Data.SqlClient.SqlError. It seems to me that the Number property in System.Data.SqlClient.SqlError is a perfect fit. According to the manual page, The Number property in System.Data.SqlClient.SqlError corresponds to an entry in the master.dbo.sysmessages table. I managed to get some numbers not listed in the master.dbo.sysmessages table: 11 (General network error. Check your network documentation), and 17 (SQL Server does not exist or access denied). It is reasonable that these network related errors do not appear in the master.dbo.sysmessages table. However, I was wondering, in addition to 11 and 17, what are other possible error code (returned by Number property in System.Data.SqlClient.SqlError) not listed in master.dbo.sysmessages table??? I remember that ODBC (in unmanaged C/C++ code) has very detailed description for EACH error code and sql state, and people always suggest that we use System.Data.SqlClient instead of System.Data.Odbc. I already tried MSDN as well as google various places without luck. Or is there any other way to do what I wish to do? Any hints/suggestions are appreciated. Thanks.

 - Remoting a collection class? I want to create a collection class (List or SortedList, etc) that is remotable (inherits MarshalByRefObject). Because C# doesn't support multiple class inheritance I can't just do this: public class Groups : List, MarshalByRefObject I know I can implement all of the collection interfaces myself but what a hassle. Is there a simpler way? Tag: VSTS Performance Explorer issues Tag: 113926

 - .NET 2.0 application stop serving ASPX pages? I've set up a development ASP.NET 2.0 application folder on a development server. This folder has been set up since at least January, and I have been working in it myself since February 2nd. It has been working fine up until this week. Three times this week it has locked up and no longer serves up .NET page requests. You can still access the files there through Windows explorer, and it still will serve non-.NET files such as ASP pages or text files through the browser, but it will not serve up any .NET ASPX pages. Even if the code inside is recompiled, or new pages are added, they are still not served up. I have eliminated any code-related issues on this, and have confirmed that if I restart IIS, then it starts working again. This did not happen for the past six weeks at least, but this week it has happened three times in four days. The lock-up today happened when I made a change to a web.config file but did not re-compile or anything, and when I hit the site again, it was doing this. I have made other web.config changes this week that did not cause this problem. Anyone else having this problem or know what is causing this? Tag: VSTS Performance Explorer issues Tag: 113910

 - Printing Anomily Hi, I have a problem that I recently solved and thought I would throw it out to see if anyone can explain why I had to use the particular solution. I have an application that prints a series of numbers to any printer. It was developed in C# for .NET 2.0 Framework. The code looked like this //variable to hold the last Page and Print settings private PageSettings lastPageSettings; public FormMain() { InitializeComponent(); lastPageSettings = new PageSettings(); } private void runToolStripMenuItem_Click(object sender, EventArgs e) { PrintDocument pd = new PrintDocument(); FormNumberer thisForm = (FormNumberer)this.ActiveMdiChild; pd.PrintPage += new PrintPageEventHandler(thisForm.RunPage); pd.DefaultPageSettings = lastPageSettings; printDialog.Document = pd; if (printDialog.ShowDialog() == DialogResult.OK) pd.Print(); } Here is the issue. The above code works fine on a Wndows XP Machine. When the application is copied to a Windows 2000 Machine and executed I get a memory error at the line pd.Print(). Now while debugging I observed that the PrintDialog placed the printer settings into pd.PrinterSettings, but not into pd.DefaultPageSettings.PrinterSettings. So therefore the two variables would contain different printers if the default printer was not used. So I made this adjustment: if (printDialog.ShowDialog() == DialogResult.OK) { pd.DefaultPageSettings.PrinterSettings = printDialog.PrinterSettings; pd.Print(); } And now everything works fine. Does anyone have a clue as to why this may be? Thanks, Bryan Tag: VSTS Performance Explorer issues Tag: 113905

 - (paritially) trusted caller exception problem Hi, I have created an simple example to show of my problem and hope that someone could help me. SecurityTest (Solution) | +---SecTest (Project, Console Application) +---SecurityLib (Project, Library) +---SecurityLib2(Project, Library) SecTest (Referenz auf SecurityLib) macht nichts anderes als using System; using System.Collections.Generic; using System.Text; using SecurityLib; namespace SecTest { class Program { static void Main(string[] args) { Test x = new Test(); x.run(); } } } the following lines are added to the AssemblyInfo.cs of SecurityLib and SecurityLib2 //Remove all Permissions from Assembly to Explizit set them with RequestMinimum [assembly: System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.RequestOptional, Unrestricted = false)] if I comment out the lines all is working fine, but i want to explizit allow permissions with RequestMinimum SecuityLib (reference to SecurityLib2) is implemented as using System; using System.Collections.Generic; using System.Text; using SecurityLib2; namespace SecurityLib { public class Test { private class InternalClass : Class1 { int _x; public InternalClass(int x) : base() { _x = x; } } public void run() { int y = 0; y = 11; InternalClass ic = new InternalClass(y); //<-----------------------Exception occurs } } } SecurityLib2 looks like using System; using System.Collections.Generic; using System.Text; namespace SecurityLib2 { public abstract class Class1 { } } It's working if I AllowPartitialTrustedCallers in SecurityLib2, but I do not want that for all classes. The question is what's the permission to set (to RequestMinimum) so that the code is working. On my reallifeproject in the additional line in the AssemblyInfo.cs are [assembly: System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.RequestOptional, Unrestricted = false)] [assembly: System.Security.Permissions.SecurityPermission(System.Security.Permissions.SecurityAction.RequestMinimum, SerializationFormatter = true)] [assembly: System.Net.SocketPermission(System.Security.Permissions.SecurityAction.RequestMinimum, Unrestricted = true)] but that has no impact on the problem itself.

 - Help! OnClick event in VScrollBar in .Net Compact Framework Hi! I tried to catch the Click event from a VScrollBar control but the Click event is not rised. MSDN says that OnClick event is suported by .Net Compact Framework and, in this case, I supose that the click event sould be rised bu VScrollBar. In this case I derived a class from VScrollBar and I overrided the OnClick protected method. I failed again because the overrided OnClick method is never called. I derived another class from Control and I overrided again the OnClick method. In this case the overrided OnClick method was called. Please, there is anybody who can tell me what is happening with OnClick method and Click event for VScrollBar control? And what should I do to catch the Click event for VScrollBar? Or what should I do to make it work OnClick overrided method in a derived class from VScrollBar? I use Windows XP Professional, Visual C# fromVisual Studio 2005 Professional Edition, .Net Compact Framework 1.0 or 1.1 Thank you in advance!

 - Creating simple exe that runs without framework? Hi all, probably a simple question for most of you: Can I create a simple executable with vb.net, that can run without the .Net framework installed? (like any executable created with VB6 in the old days..) I would like to stay away from permissions, strong naming GAC etc. for some simple tools... Thx, Marcel P.S. Why is it that .Net ships with command line tools that could easily be implemented with an interface???? (sn, gacutil, caspol..) Tag: VSTS Performance Explorer issues Tag: 113891

 - Ngen process during installation of .net framework 1.1 Hi everyone, I have observed that the ngen process appears in the list of processes in taskmgr while .net framework 1.1 gets installed. This process consumes 0-50% of cpu and 0-20K of RAM. I would like to know if this process can be a cause of slowing down performance of a high speed application. The installer of this application examines whether .net framework is installed, if it is not installed it first installs .net 1.1 and then continues with its own installation. It would be great if anyone knows about problems related to ngen during installation of .net framework 1.1, say, under low memory conditions, or for particular OSs, or for particular hardware configuration -- Thanks, Sameeksha MCAD.Net Tag: VSTS Performance Explorer issues Tag: 113882

 - How To Get Permission to Call File.SetAccessControl? My program needs to update the access control rules for a file (actually a virtual COMM port). I have the code working on my development machine. But when run on a different machine (or same machine with another account), it fails with a System.UnauthorizedAccessException. I presume it is because on my dev machine/account my account is a member of the Administrators group and on the other machine/account it is just a normal user. But I need to have the code work for a non-admin user (basically any user). What do I have to request to get this level of permission and how do I get it? Thanks.

 - Trusting Assemblies Problem Hi all, I have an issue with trusting assemblies, I have a console app and which I have transferred to a server and use a batch file to run the exe. I have figured out that I need to trust the .exe for it to run on the server. Problem is: any modification to the exe and copying the exe to the same location does not run the program, it has to go through the process of trusting again even if the change is minimal. How can i avoid this? Thanks, Stephen Tag: VSTS Performance Explorer issues Tag: 113878

 - Need 1.1 and 2? I am only using dotnet for apps that we installed that need it. This is a dumb question but do we need both 1.1 and 2 or will just 2 do for our simple need? Sorry to be so stupid about it but never can't find an answer on the net. Thank you. Tag: VSTS Performance Explorer issues Tag: 113876

 - RegisterAssembly, CreateComInstanceFrom and IsCOMObject I am registering a managed class as a COM class via RegistrationServices.RegisterAssembly, then I am instantiating that class via CreateObject, then I am testing if the object is a COM instance via Type.IsCOMObject. Surprisingly (to me) the return value is False. This is a problem for me, because I am using managed code to write a OWC spreadsheet addin, and memory allocated by the addin is not freed when the spreadsheet is destroyed. I wanted to explicitly invoke InteropServices.Marshal.ReleaseComObject, but it is failing, presumably because the object returned by CreateObject() is, in some way, not a COM class. Can anyone explain why the IsCOMObject is returning False, and what I might be able to do to make it return True? Sub Main() Dim lvType As System.Type = GetType(ComClassTest) Dim lvRegistrationServices As New Runtime.InteropServices.RegistrationServices() lvRegistrationServices.RegisterAssembly(lvType.Assembly, Runtime.InteropServices.AssemblyRegistrationFlags.None) Runtime.InteropServices.RegistrationConnectionType.SingleUse) Try Dim lvObject As System.Object = Microsoft.VisualBasic.CreateObject(lvRegistrationServices.GetProgIdForType(lvType)) Debug.Assert(True = lvObject.GetType.IsCOMObject, "CreateObject creates a COM object") ' this assertion fails Finally lvRegistrationServices.UnregisterAssembly(lvType.Assembly) End Try End Sub Tag: VSTS Performance Explorer issues Tag: 113874

 - "unable to write data to transport connection" error Hi everybody. Yes, I know there are a number of posts about this, but many of them have not been answered and of those that have been, I can't find one that exactly fits. I am working in vb.net using a TCPClient object and sending commands to a remote, IP-aware device. All goes swimmingly for a while, then I get the above error. The exception's "InnerException" is a "SocketError", with the message, "An existing connection was forcibly closed by the remote host" It's usually about 5 minutes or so before it gives up. The client who owns the device says another version of our software connects fine all the time, via a serial-to-ip conversion device/program. So it's unlikely to be the device itself, despite the inner exception message. I have tried both send and receive timeouts on the TCPClient - no change. I am at a loss - any ideas out there? TIA, Peter Royle Tag: VSTS Performance Explorer issues Tag: 113864

 - System.Configuration.Install.Installer and console I have a Windows service exe that derives from System.Configuration.Install.Installer The exe can be executed from the command line with parameters such as INSTALL, UNINSTALL, START, and STOP to perform such tasks on the service But the exe is also the exe that _is_ the service process, so when it's run with no parameters (by the SCM?) it calls System.ServiceProcess.ServiceBase.Run ( srp.ServicesToRun ) ; The problem then is when it's accidently run with no parameters from the command line. Is there some way for it to know whether or not it's being executed by the SCM? I'd like it to be able to give a help message and terminate when it's run from the command line while still behaving properly when running as a service.

 - Copying a flash mem card, including boot sector. Is there a .NET framework call that will make an exact copy of the contents of a disk, including the boot sector if there is one? What I have is a Windows CE device that boots from a compact flash card. This device goes out to customers, where it runs a machine for them. I want to make a utility that will allow them to back up and restore their system. I know how to copy the files and directories from a disk, but that doesn't result in a new, bootable, disk. I could tell them to use Norton Ghost, and that would work just fine, but I have already created a utility for managing the information on that disk. It's a C# .Net framework 2.0 application. I would like to add a "make backup disk" button to the menu of that utility, but I don't know how to copy the boot information. Tag: VSTS Performance Explorer issues Tag: 113861

 - Using ManualResetEvent within a ContextBoundObject 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. Tag: VSTS Performance Explorer issues Tag: 113858

I'm trying to use the VSTS Profiler on a fairly large and complex .NET 2.0
application. In the past, I've always used the Compuware tools (especially
the Community Edition of their profiler) and am in general quite familure
with application tuning in .Net.

The application in question is a Windows Forms EXE with about 25 project
(all DLL's) under it, written using C# and a little of bit Managed C++. My
test environment is a Windows XP Professional machine and almost everything
is being built as "Any Cpu" (and what's not is being targeted at the x86
runtime).

When I create new performance session, I add in the "TestHarness" project -
this is the Winforms app that drives the DLL. In production this is a
Windows Service, but for testing I use the WinForms driver as it's alot
easier.

... so I create a performance session, add my TestHarness in, and try to hit
"Run". Unfortunatly the "run" button in the performance explorer is greyed
out. I've tried every means and mechanism I can think of, but it's always
greyed out. I've exited and come back in. I've switched between
Instrumentation and Sampling. I've kicked; I've screamed; I've yelled. I've
gone through the Wizard. I've done things manually. I offered up a prayer to
Bill and Steve. No dice.

I can run the application normally - I can set breakpoints, debug, etc. This
all works fine. It's just the Profiling infrastructure that seems to be
broken. If I create a little sample app, everything works fine. So I know
the installation of the profiling infrastructure is correct, and I know the
general process I'm using is valid.

I'm at my wits end in terms of getting this to work. I had really hoped this
would do the trick now that Compuware has stopped offering a free version of
their profiler - but so far I'm not not making much headway.

So to further complicate the issue, I have successfully run sampling
profiling.

When I switch to instrumentation profiling I get a message box saying 'Value
does not fall within the expected range.' and then the launch button greys
out. To get the launch button back I have to restart the Visual Studio
application.

Instrumentation is much more usefull for what I'm doing than sampling, and
hopefully some resolution will make itself apparent soon.
