    - "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...

    - Network aware application 'a la MSN' I'm about to write a network aware application. Of course I intend to do UDP broadcasting to detect other app on my network. But I would like my application to be usable over the internet as well. Between to end user computer. Ideally if user could connect through MSN identity that would be perfect!

    - error message on shutdown Greetings. I am not sure if this is the group place to be asking this question. But will do so. I have recently started the asp.net and iis in the MyComputer/Manage/Services and Applications. Now, since starting asp.net I get the following error message when I go to shutdown or restart my computer. The message reads; "The instruction at 0x0074006e referred memory at 0x0074006e. The memory could not be "read."" In the title bar it has; asp.net_state exe Application error I redid the regiis to map asp and iis together thinking this was it but it still appears. It is during the "Shutting down Windows..." that it appears. I am puzzled why I am getting this. Anyone have any ideas? Thanks in advance to anyone responding. *** John Tag: ClickOnce and updating client applications Tag: 107506

    - 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?

    - 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: ClickOnce and updating client applications 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: ClickOnce and updating client applications 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: ClickOnce and updating client applications 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: ClickOnce and updating client applications 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?

However, it seems like there is no implementation of this function in the .NET framework. Is that true? is there no way to create a codecompileunit object from a sourcecode?

    - 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: ClickOnce and updating client applications 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. (Plus If I cannot use CAB can I make it source work on dot net 1.1 or at least can i see its Class Diagram Design?) Thanks --- hB Tag: ClickOnce and updating client applications Tag: 107430

    - Visual design tools and DAL in VS 2005 / .NET 2.0 Hi I wrote quite a few apps with .NET 1.0 and 1.1, which made use of a Data Access Layer, and also used the Microsoft Application Blocks for Data Access (v2). In VS 2005, there is a huge improvement in 'visually' designing the data access, and binding it to the controls on the form. I have 'played around' with the SqlDataSource component, which allows very quick, easy and simple access to a SQL DB. However, I have a couple of considerations, which I would like to get opinions on.... 1). If I want to use a common ConnectionString (ie. just have it coded in one place), how can I bind each of my controls to this connection?? (ie. I don't want to change 100's of controls if my connection string changes). 2). I want to keep in mind the 'Enterprise' way of doing things, via a DAL or Business Layer. Does anyone have any good source (C#), which shows the implementation of a Front end, DAL, and the component bindings. This can be using SQL commands, or Stored procedures, but I would appreciate details of Updates / Inserts etc, as well as simple selects (so that I can see the impact on Table Adapters etc).

    - HttpWebRequest / Response disconnect question Hi all, I'm trying to figure something out and not quite sure if I'm doing it the right way. First, the quick overview and I'll post more info if it's needed. On my web site, I've got an HTTP Module that serves binaries. It basically just reads them from disk and streams the bytes to the client. This works fine -- every 10k I check if the client is connected, and if so, read another 10k, etc. I have another process that pings a few URLs using an HttpWebRequest and HttpWebResponse. If the content type isn't plain text or HTML, I don't try to read the site content and instantly try to close the connection. I was hoping this would prevent the files from being downloaded (some are quite big), but that's not the case. If I debug both the web app and the pinging utility, I see the request made, and the first bit of of data is pushed to the app. The app sees the content type, and attempts to close the connection. The thing is, the close() call doesn't return until the module is done streaming. Each check to see if the client is connected is still returning true (which it is, since the client hasn't disconnected yet). When the module is done streaming the content, the close call in my app returns. Any Ideas? Happy to post more code. Ideally I want the close call to instantly sever the connection... Thanks!

    - Q: how to do stable sort in ArrayList? Hello, Here is my problem: I have an ArrayList with duplicate keys. I 'd like to preserve the original order when sorting the list by using ArrayList.sort(comparer* c). However when the comparer returns 0 (meaning the two objects are equal), the order of the two objects are random or not preserved. I understand it's not a stable sort. I also tried to return just -1 in my compare class when they are equal. But this created a deadloop inside ArrayList.sort() for unknown reasons. Does anyone know to how get around this? Thanks.

    - How to specify the filename when exporting from a servlet an XLS? Hi, I have a servlet that generates a report and exports it as XLS.

For setting the name I use: response.setHeader("Content-Disposition", "inline; report.xls"); When I want to save the file, the file name is not report.xls as expected, but ReportGenerator.xls(the name of the servlet that generates the report) Even more if I use: response.setHeader("Content-Disposition", "attachment; report.xls"); everything works as expected.

    - Internet Explorer CLR Integration Are there plans to integrate the CLR with Internet Explorer? Could that happen in IE7, or will .NET only be distributed by Microsoft with future Windows (Vista) and previous versions' service packs? Also, does anyone foresee client-side scripting being handled by the CLR in the future... and would they even consider exposing framework libraries to an IE CLR scripting host. Or is this just garbage because windows forms controls can already be hosted in IE? -Andrew Tag: ClickOnce and updating client applications Tag: 107393

    - Validation / Logic Layer architecture Hi, I am working to clean up an application that is split into 3 major layers (asp.net, logic, data). In the logic layer, many of the methods seem to have a fairly lengthy validation process, which is eventually followed by the real purpose of the method. For instance, if I have a method that passes in a series of parameters, each parameter is checked, validated and in the case of errors, the appropriate message is generated to be passed back to the presentation layer. Finally, if all the validation has passed, I can call the data layer modules to perform the updates to the various tables. Does it seem extreme to split this logic layer into two separate layers (validation and logic)? Is there a cleaner way to perform validation in the logic layer? The methods always look similar to this: If() Createerror("msg") Else if() Createerror("msg") Else if() Createerror("msg") Else if() .. Else { DoLogic1() DoLogic2() DoLogic3() } Sometimes the validation is really long. hheh, and it makes me sad. Oh well.. If this is a small issue and nobody really worries about this, then please let me know too! Tag: ClickOnce and updating client applications Tag: 107387

    - ASP.NET 2.0 Frustration - MS Please Help I have a request of Microsoft and I hope they see this. I use Visual Studio 2005 Pro and WIN XP Pro with IIS 5.1 I have spent the better part of the last 2 weeks attempting to get my ASP.NET projects to work. Just a simple hello world. Since installing the 2.0 of the framework, localhost no longer works on IIS. localhost is required for (at least it appears so) for the ASP.NET development server to function. Actually I take that back. localhost will work but now is very slow but not with anything ASP.NET. the development server icon appears, gives it a port uses localhost but it wont work. All I get is page cannot be displayed. I get errors when trying to set up the quickstarts such as: Failed while restarting W3SVC. Error code: 0x8007041d Though it actually will start. When I go to check it is running. I also get htis error under system: The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID {0C0A3666-30C9-11D0-8F20-00805F2CD064} to the user COMPUTER11\IWAM_COMPUTER11 SID (S-1-5-21-1292428093-839522115-725345543-1026). This security permission can be modified using the Component Services administrative tool. I got to Component Services and of course no such entry(0C0A3666-30C9-11D0-8F20-00805F2CD064) exists under COM under DCOM config. Is it possible MS could put out a tool that would configure IIS (and Windows if necessary) to work with ASP.NET 2.0 so I can actually move on from here. Right now, I am flat out stuck. I have uninstalled the Framework 2.0 and IIS, and reinstalled IIS and then the Framework. I have registered so many times. If I seem frustrated I apologize. This should not be that difficult.

    - Load Tree View from Configuration Block Hi guys ok ok I know i can read the xml directly to a treeview, but I think the configuration block is more useful for me since it caches nicely and i like frameworks to be used. Ok what i wanted to do was have a nicely structured config file to read into a treeview, e.g <Node> <Node1.1></Node1.1> <Node1.2></Node1.2> <Node> <Node2> <Node2.1></Node2.1> <Node2> all fine and dandy but i cant read this out of 1 config file eg. here's the config file <DealTreeSettings> <xmlSerializerSection type="ConfigurationQuickStart.TreeData ConfigurationRuntimeData, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"> <TreeData xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <SpotName>xxxxx</SpotName> <PreciousName>xxxxxx</PreciousName> </TreeData> <TreeData1 xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <FxOptionName>yyyyyy</FxOptionName> </TreeData1> </xmlSerializerSection> </DealTreeSettings> Now I cant create mulitple xmlSerializerSection so how do i read all the nodes ? ie read both TreeData and TreeData1. i can read the first lot of nodes by name nicely from the class and populate the treeview eg <SpotName>,<PreciousName> problem is i dont want to add all the nodes under the TreeData since i dont want additional logic when building the view.

    - Detecting memory card/USB device insertion - how to? Hi, I want my app to respond to attachment of a memory card (SD) and/or a particular type of USB device to a client PC. Both devices have on them the same file/directory structure - i.e. a directory structure recognisable to my application. What I would like to do is have my .NET Windows Form app start automatically (if it is not already running) when either device is attached to the machine, and have the files pre-selected in an explorer-like window for the user to take further action with. Adobe Elements does this, for example, when I attach my Compact Flash card to my PC - it seems to use a Windows Service called 'Adobe Active File Monitor' that runs constantly in the background. Any ideas how to do this, or better still any code out there that already does this? I don't think the .NET FileSystemWatcher will work for removable devices, so I suspect that a bespoke polling component is needed. If so, how is it best to detect the presence or otherwise of removable drives? Thanks, Chris Tag: ClickOnce and updating client applications Tag: 107355

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
