    - Directory of assembly when using services Hi all, normally, when starting a service the current directory (System.Environment.CurrentDirectory) is the system directory of the platform. The service itself can be started from another location e.g. c:\foo\bar\myservice.exe . Is there a way to get the directory the service executable was started from, in my example c:\foo\bar\? Kind regards and thanks for your help in advance, Michael Tag: Detecting if a remoted object really exists Tag: 107586

    - Detecting file changes just like Visual Studio I want to mimic the functionality of Visual studio where if an opened file is modified outside of the IDE, the user is prompted if they wish to reload the file(s). What is the best approach to do this. I have read different postings about the FileSystemWatcher class where there seems to be plenty of problems and hacks required when using this class (e.g. duplicate notifications) etc. What should I use - FileSystemWatcher or some alternative ? thanks, Des.

    - File preview in Windows Forms application Hello I am creating a small C#.NET 1.1 Windows Forms application, which looks up power point files in a target directory. Now, what I wanted to do was have a preview of the 1st slide of the powerpoint file in a small area of the window. Is this possible? If you want to see what I mean, in windows xp, if you open windows explorer and go to a directory with power point files, in the left pane you should see some panels ("File and Folder Tasks", "Other places" and "Details"). If the details panel doesn't show anything, clikc on the downward arrow beside it and it should expand. After doing so, select a power point file and in the Details panel in the left navigation pane you should see the first slide of the power point presenation that you selected along with the name of the file, the type of file, data modified, size, etc. Please make sure that you have the "Folders" button at the toolbar de-pressed so that you see the panels in the left pane as I am describing and not the file tree view.

    - .NET Framework 1.1 SP1 problem under ASP.NET. I have an ASP.NET application that makes a TCP remoting call to a managed C++ application through a managed C++ DLL. Everything has worked fine for some time now up until I have installed SP1. Now, what happens is that the remoting call fails if I copy any updated assembly DLL to the ASP.NET web site. It even happens if I update web.config. The only way to fix the problem is to restart IIS. This did not happen before applying SP1 to .NET 1.1. Does anyone know of this problem and if there is a fix? -- ----------------------------------- Ken Varn Senior Software Engineer Diebold Inc.

    - how to determine whether a datarow is null or not Dear sir, I am trying to find a row in a dataset. I know I can define a primaryKey and use rows.find(key) to locate this row. However, very often this row does not exists, what can I use to determine whether this row exists or not?? >Dim objSet As New DataSet >objSet.ReadXmlSchema("e:\abc\test.xsd") >objSet.ReadXml("e:\abc\test.xml") >objSet.Tables(0).PrimaryKey = New DataColumn() {objSet.Tables(0). Columns("GroupId")} >Dim datarow As DataRow = objSet.Tables(0).Rows.Find(9) Now I need to determine whether it finds the row with key=9 or not?

    - Difficulty with Remoting and IPC Channels I'm trying to get an Remoting proof of concept working. Using TCP and/or HTTP Channels, the proof of concept works fine. However, when trying it with the IPC Channel, I get the following RemotingException when exectuing the client piece: "Failed to connect to an IPC port: Access Denied" I can't seem to find any useful info regarding this error message and what it means exactly.

    - confusion working with setup project? Hi, I have a VB.NET 2003 project framework 1.1.4. I would like to create a setup project with the following structure for the final installation when the setup.msi is run. C:\program files\company name\progname (this I have completed) the the programe name directory I would like to have the exe file, the app.config, and 3 text files that I have containing other config data. then in the bin directory all the dependency assemblies(dlls). The problem: When I am debugging the application the 3 text files are'nt found unless they are in the bin directory of the project. I am using Application.StartupPath to find the text files. They are only found when they are in the bin directory where I don't want them to be. The debug .exe is created in the bin directory which I thinks explains some of this. Also, when I make the setup.msi file and run it, the dependency files in the bin are not found by the exe application which is in the root. If I copy the dendencies from the bin into the root, it works fine. the only way I can get it to work is all the text files and dependency dlls in the same directory on the root. I want the dependencies in the bin, the text files in the root, the exe in the root, and the app.config in the root. I've messed around for hours and cant' get this. please advise. thanks Chris Tag: Detecting if a remoted object really exists Tag: 107543

    - Connecting to strong-named DLL outside of appbase Hi again, I'm working on an app that will be using an assembly that will be sitting on the network.

    - Generic Union Type with Explicit Layout I am desperately trying to build a generic union type with explicit field layout. First, I will show you my attempt without generics. This is something like a tagged union in functional languages like F#. Thus let us first write an example using F#, which is rather short (assuming polymorphic types 'T stack and 'T queue already defined) --- type 'T ProcessingOrder = Stack of 'T stack | Queue of 'T queue;; --- This defines the generic type ProcessingOrder to be either a stack or a queue, with explicit tags Stack and Queue. 'T is the type parameter. As I have found out using IL DASM, F# circumvents my problem by using auto layout and thus does not create a real union type, wasting space. Let me define the same type using C#: --- [StructLayout(LayoutKind.Explicit)] struct ProcessingOrder<T> { [FieldOffset(0)] public readonly object _object; [FieldOffset(0)] public Stack<T> _stack; [FieldOffset(0)] public Queue<T> _queue; } --- Note that I use implicit tagging, as classes in .NET are already tagged. One may explore the actual type of the union by typeof(_object). Propably not the fastest way. Unfortunately, this does not work. Compiles without error messages but at execution a TypeLoadException is thrown, which tells me that explicit layout is not allowed for generic types. Au contraire, a specialized implementation works fine: --- [StructLayout(LayoutKind.Explicit)] struct ProcessingOrderInt { [FieldOffset(0)] public readonly object _object; [FieldOffset(0)] public Stack<int> _stack; [FieldOffset(0)] public Queue<int> _queue; } --- Has anyone an idea why explicit layout is forbidden for generic types? Has anyone an idea how to circumvent this without accouting space for every choice? TIA, Hagen Tag: Detecting if a remoted object really exists Tag: 107537

    - ClickOnce and updating client applications I'm trying to understand the limitations of ClickOnce deployment, and have a question regarding how automated client application updates can be. I have a server .NET application with a client application that connects and uses .NET remoting objects in the server app. I need to be able to deploy updates to the server and/or client, and I hope ClickOnce will suit my deployment strategy. My question is, if an update for the client application is available, can the client applications that are currently connected to the server application be automatically forced to update? I'm concerned that ClickOnce will only prompt users to update when the client application is restarted. Regards Boz Tag: Detecting if a remoted object really exists Tag: 107521

    - "Cannot find assembly..." when deserializing from memorystream I have a strange exception imo when I try to deserialize a memorystream to an object using the following code: public static object Clone(object sheep) { if (master == null) { throw new ArgumentNullException("sheep"); } using (MemoryStream stream = new MemoryStream(4096)) { object dolly = null; BinaryFormatter formatter = new BinaryFormatter(null, new StreamingContext(StreamingContextStates.Clone)); formatter.Serialize(stream, sheep); stream.Seek(0, SeekOrigin.Begin); dolly = formatter.Deserialize(stream); return dolly; } } The Exception is thrown by the formatter.Deserialize() method call: "cannot find assembly x.dll...". For some reason the Deserialize() is trying to look presumably in the GAC for the x.dll assembly. The object 'sheep' I am trying to clone is in the same assembly as the utility class with the Clone() method. Anyone has experience this before? I am using .NET Framework v1.1.4322...

    - entering internationalized input I have implemented an international text editor based on uniscribe, GDI & GDI+. While it display internationalized text fine I realize user input are no good. So far what I do: I override Control.OnKeyPressed(char keyCode); I was expecting the appropriate char to be passed on. Now I test with (very simple) french accent. I was trying to type: 'ê' and I ended up with "[e" So, how do I get a char which is a combination of multiple key strokes? There must be an API for that, wouldn't it?

    - Access Addin Hello, I'm trying to develop an access addin and I'm relatively new to developing addins for Access. Basically, I need to log certain queries that are sent to the database. However, I can't find an event anywhere that will allow me to see the query string. Does anybody know how I can at least just see the query string every time there is a query?

    - Type switch? I am trying to do a switch on a Type. It's actually a DataType used to type a column in a DataTable. I have run through several blogs and am not sure what I'm missing or why it can't be done. My switch statement looks like this: int typeEnum = myObject.GetType().GetHashCode(); switch( typeEnum ) { case ( typeof(System.Int64).GetHashCode() ) : bool ThisIsABigInt = yes; break; That does not work. But this does: string typeEnum = myObject.GetType().ToString(); switch( typeEnum ) { case "System.Int64": bool ThisIsABigInt = yes; break; The method that does this switch gets called around a zillion times, and all of that ToString() seems like a problem. What is the best way to simply switch on an instance Type to perform an action? There are 30 Type tests and I don't think writing 30 if statements is the right way to do things. Is it? Thanks.

    - Asynchronous WebClient I'm trying to automate a process of logging in to a website and posting and downloading some stuff. I am using asynchronous WebClient methods so the user can cancel the operation at any time and it's working fine, but I have a question about the structure of my program. Right now I've got something like this: Main() { WebClient LoginClient = new ... // set the relevant properties and eventhandlers LoginClient.UploadValuesAsync(...); } LoginClient_UploadValuesCompleted(...) { if(!Cancelled && !Error) { WebClient Page1Client = new ... // set the relevant properties and eventhandlers Page1Client.DownloadDataAsync(...); } } Page1Client_DownloadDataCompleted(...) { if(!Cancelled && !Error) { WebClient Page2Client = new ... // set the relevant properties and eventhandlers Page2Client.DownloadDataAsync(...); } } etc. I've got about 5 or 6 pages I need to get and I have to get them in order, so in each request's completed event handler I start the next request. Is this the right way to do things? There seems to be a fair amount of repeated code and it just feels a little strange, but it works fine. Also, whenever I start the program and start the first request for the first time it blocks for about a second even though it's started asynchronously. No other requests block, even if I cancel and restart the request sequence. If I restart the program, the first request blocks again. Is this just because some initialization occurs in the background or something? Is there any way to avoid this? Tag: Detecting if a remoted object really exists Tag: 107466

    - Wellknown-Singleton object is being created 2 times Hi, I have a singleton class which I want to "create" (call it's GetInstance() for the first time) in server process, and after some time I want to use it in client process, through .Net Remoting. I define the singleton as MarshalByRefObject. My server process looks like this: 1.Register singelton type as being wellknown singleton (not singlecall). 2. Singleton.GetInstance() 3. Console.Write("Singleton constructor called"); 4. do some logic inside the singleton 5. Wait for clients to connect Client process looks like this: 1. Register singleton type. 2. Singleton.GetInstance() After this call, "Singleton constructor called" is being printed AGAIN on the screen, which means that the singleton object is being created again, and thats not what I want. I want to receive proxy to the same singelton, already created in server process. I don't understand what I do wrong. Please help, Mike. Tag: Detecting if a remoted object really exists Tag: 107457

    - ANN: OleDBProNet for .NET version 2 is released at www.udaparts.com Hi, All: OleDBProNet is a .NET class library which is a complete, feature-rich, and extremely powerful data access solution for .NET programmers through MS OLEDB technology. It offers the following key benefits over ADO.NET: 1. Extremely simple: OleDBProNet hides all of complexities of raw OLEDB programming. It is written with the classical ADO data accessing model. You will never meet BLOBs and other complicate data types conversion to bother you for all types of SQL statements. OleDBProNet comes with fifteen real and advanced C# and VB.NET samples to assist your developments no matter what programming background you have. If you have somewhat background in old ADO (Active Data Objects), you will feel OleDBProNet is extremely simple and intuitive to use. 2. Many features available: OleDBProNet supports all types of client and server cursors as shown in the attached samples. It supports all of advanced rowset navigation features (bookmark, record searching, index, bi-directional scrolling and jumping etc) directly on server side. OleDBProNet offers much more features than ADO.NET. 3. Super performance: OleDBProNet is written from Visual C++ 2005 C++/CLI with direct use of raw OLEDB interfaces, which almost eliminates data marshaling across layers between native and managed codes completely. Also, OleDBPro uses batching mode (20 records per batch) to retrieve and update records by default. Generally, OleDBProNet is about five times as fast as ADO in .NET environment. Also, OleDBProNet is about 15% faster than MS OleDB.NET provider. OleDBProNet can manage huge data records using server cursors, but ADO.NET can't. Therefore, OleDBProNet is significantly faster and simpler than ADO.NET for accessing a large number of data records. 4. Complete solution to all types of your databases: OleDBProNet is a complete solution to all of types of databases, SQL server, Oracle, Access, MySQL, DB2, ....... As long as you have an OLEDB provider, or ODBC driver, or ISAM driver available, it will work for you with one copy of code. -- Yuancai (Charlie) Ye Fast accessing all of remote data sources anywhere with SocketPro using batch/queue, non-blocking and parallel computation See 30 well-tested and real OLEDB examples at http://www.udaparts.com Tag: Detecting if a remoted object really exists Tag: 107456

    - IDisposable and Finalization I believe that I fully understand the concepts behind IDisposable and finalization (at least I hope I do) and I would like to get feedback from the experts so that I can forward them on to others. There are people who think that if a class implements IDisposable then it should include a finalizer. What I told them was that you should only include a finalizer if you have unmanaged resources you need to ensure are cleaned up. Otherwise you should not include a finalizer whether or not you implement IDisposable. As an example of this case, the one where you might want to implement IDisposable but do not need a finalizer, I said assume you have a class that internally makes use of a FileStream object. It might open the object up at some point during its lifetime and keep it open from then on. In this case you might want to implement IDisposable to provide an explicit mechanism for the caller to indicate they are done with your class. The implementation in your class would simply call the FileStream's IDisposable.Dispose() method. I argue that this class does not need a finalizer and in fact if this class did include a finalizer it would be of no use. By the time the finalizer was called you could not do anything with your FileStream instance as it may have already been disposed (assuming you don't expose the instance outside your class). Is my statement/explanations valid? -- Thanks, Nick Tag: Detecting if a remoted object really exists Tag: 107452

    - Process.HasExited property does not work as expected I've created a windows service to ensure another service is running. First of all, I look for the process relative to the service I'm monitoring. The code is: Process[] processes = Process.GetProcesses(); foreach(Process process in processes) if(!process.HasExited && process.Id > 0 && process.ProcessName.ToLower() != "system" && process.MainModule.FileName.ToLower() == serviceDetail.ExecutablePath.ToLower()) ... The problem is with the MainModule property, called at the end of the if statement. Internally, the MainModule property gets all modules for the process and looks for the main one. So, if the process has exited, the search for the process modules fails and we get an exception. In order to solve this issue, I test the HasExited property at first place. However, I still get an exception: "Cannot process request because the process (3248) has exited." Why this exception occurs if I have tested the HasExited property? Am I doing somethig wrong or missing something? Another exception is thrown too. Sometimes I get an "Access is denied" exception from this code piece. Does anyone have any idea that could help me?

    - badPwdCount and old user passwords Hello, trying to authenticate my users against active directory in an webservice. Webservice is on an Win2K3 Domaincontroller for testing purposes. Therefore I have checked two methods: 1. I use the system.directoryservice method, with "LDAP" search path, username, userpass. 2. I use the LogonUser function in lib advapi32.dll. My domain policy says, that the useraccount will be locked after three wrong passwords. Also I set, that the users password may not repeated in 24 password cycles. With both methods i can check username and password. Both Methods working well for me. Supplying a wrong password will increase badPwdCount property in active directory and after the third wrong password the account is locked. But, I tested this behavior also with old, previous used user passwords. If I send an old user password the counter badPwdCount will not increased and so, the user will never be locked. Is this by design or a bug? I'am asking, because I expected if a user takes a wrong password, he will take one of his old passwords and not an totally different, wrong password. BTW: It seemed, that the badPwdCounter is readonly. I can't set it manually. Thanks ahead, Carsten Tag: Detecting if a remoted object really exists Tag: 107435

    - UserInterfaceProcess AB and CompositeUI AB Hi, (I do not know which is the exact newsgroup for this post) I am doing application based on SOA. My client app is winforms and we are targeting it as smart client. I know about MVC in general. And I am puzzled how to go with MVC in my this Smart Client User Interface (winform based) app. First I see UIP AB and then CompositeUI AB. UIP AB looks additional complicated for smart client app considering Model part and interaction of model with other in MVC. While I like WindowsFormControlView because we do not have interfaces like series of Form instead one Form. Note I want to work striclty on Dot Net 1.1. Desc: I have an MDI app client side ui, which is a smart client that it only talks to server thru Web Svc (the most fundamental part of smart client apart from rest). SOA is already there. I want my Client UI MVC driven. 1) Dot Net + MVC = UIP AB (app block) 2) Dot Net + Smart Client + WinForms = CompositeUI AB (CAB) For 1) I can have separate controller for separate view (winform or user control) or one for all or ... Model is Web Svc. Or like on smart client there is only view and controller and model thing is web svc which is on server. Fro 2) I can have my UI as (user controls plus winforms) as smart widgets and achieve my objective through CAB. Now what you ppl suggest? Please advice.

    - 2.0 Beta has no XML namespace Hi, I download and install VB.bet 2005 Express and also dotnet frame 2.0 Beta on my pc. I want to try XML functions, but there is no XML namespace under system!! Where is could I find it. P.S When I try to install dotnet frame 2.0, it indicates that I should uninstall 2.0 Beta first. After I unstall 2.0 Beta and install dotnet frame 2.0, VB.NET 2005 express cannot work anymore. thanks Tag: Detecting if a remoted object really exists Tag: 107427

Hi,

is there a chance to find out if a proxy to a remote object is dead without
calling a method on the proxy? I have written a frontend for a service, the
service itself is the remote object. When I first start my frontend
everything works as expected, the call to Activator.GetObject() returns
null. But when I start the service and the stop it again calling
Activator.GetObject() returns me a TransparentProxy. Any ideas?

Regards,
Michael
