    - SP vs .NET results Hi Can someone give me guidance on the following scenario? I have a windows service application that kicks off a job that perform complex processing and call a stored procedure that run for +- 45 minutes. I need a mechanism to notify the service to throw an exception when the database connection is lost or there's a critical error on the database server. Currently, if there is an error on the database, say db connection, no notification is sent. The windows service fire the jobs using multi-threading.

    - Just a question When will managed Windows forms get as fast of their counterparts in C/C++ ? I think if there is only one weak point in dotNet performance, it is its slow win forms, which make Win developers like me to deny the full power of .NET. It is not just the load time that teases, we have too much overhead with heavy treeViews and listViews that sometimes make us giving up the whole project on .NET and going back to C++. Thanks for any help. Tag: Transaction code causing runtime exception Tag: 97351

    - Exit Code 67 I have a fairly simple Windows Forms application developed using C#. It basically listens to two serial ports and displays the results. There are three threads that each listen to a network socket. Additionally there is the GUI thread, the two serial threads, and some threads to process the data from the serial ports. For the serial communications I am using John Hind's NETSerialComm wrapper library. Occasionally, the tool will exit with error code 67. When you look that up, it is listed as "The network name cannot be found." At the time it happens there are no network connections, just three sockets in listen state. It can happen after 12 hours or 3 days. Or not show up for a while. Any insight into why this might happen is appreciated. Dave Uhrenholdt Tag: Transaction code causing runtime exception Tag: 97347

    - Transaction spanning multiple business classes Hi I have a problem on how to span a transaction over multiple business classes without using COM+ Example: A existing person get an MailingAddress assigned to public class PersonService { public void InsertMailingAddress(data) { //ask the AddressService to insert an address new AddressService().InsertAddress(); //update the person with the ID from the newly inserted address } } As you can see, this should be in a transaction --> Insert Address --> Update Person How can i span this in a transaction without passing sqltransaction objects in the businesslayer? Any ideas??? Tag: Transaction code causing runtime exception Tag: 97346

    - problems with Microsoft.Enterprise.Library I am trying to use EnterpriseLibrary packages in an IOC pattern. Note on implementation: I have LoggingServiceManager which is tightly bound to a Logging Application Block and implements an interface ILoggingServiceManager. ILoggingServiceManager is contained within an asssembly CommonServiceManager. My intended user (a class cMain) would refer to the CommonServiceManager and using ILoggingManager interface invoke methods of the Logging Application Block. Issue: The Logging Application Block uses run-time binding and hence needs references of Logging Application Block at the cMain level. And this breaks the IOC pattern completely. Has anyone comeacross such a scenario with Application Blocks. this problem occurs with Logging, Caching and Cryptograpghy Application Blocks (so far...).

    - Windows Service Deployment problem I get the following Log in EventLog on attempting to use a custom action to write to a config file in the to be installed application after a call to the base Install method. The description for Event ID ( 11001 ) in Source ( MsiInstaller ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: Product: DOILoadWindowsService -- Error 1001. Exception occurred while initializing the installation: System.IO.FileNotFoundException: File or assembly name DOI, or one of its dependencies, was not found.., (NULL), (NULL), (NULL). Without this custom action, the install works OK, with it, it fails every time. The custom action uses CustomActionData as follows: /WATCHED=[WATCH] UPLOADED=[UPLOADED] ERRORS=[ERRORS] ERRORFILE=[ERRORFILE] where the values are collected from a UserInterface TextBox object. Without the custom action, the folders referred to above are created every time but I want the user defined paths to be written to the config file so that they can be accessed by the Windows service when it is started or running. What is going on here? How can I sort this out? cheers -- PeterW Tag: Transaction code causing runtime exception Tag: 97340

    - Execution in Visual Studio vs Native Execution With regards to running a project in the Visual Studio developement environment as opposed to executing the exe directly from the hard drive..... I am developing an application in C# using VS.NET 2003...my application seems to respond differently when i run it using the development environment as opposed to when i run it directly from the exe. For instance, in my code i have a try-catch block and inside the try block i explicitly throw an exception and i handle it , for example, with a msg box or something. This works fine when i run it using Visual Studio (even when running a Release build) but when running it directly from the exe the dreaded "An unhandled exception has occurred in your application. If u...etc" dialog box appears. What is the reason for this? I am really stumped and dont know what i can/should do since this is an intergral part of the application. Any help will be greatly appreciated. Tag: Transaction code causing runtime exception Tag: 97337

    - Write to config file from deployment project I have a deployment project where I collect the paths to 4 user defined directories using user interface textboxes that are then mapped to folders in the file system editor that are always created. This all works fine. What I want to do is update the config file for the application so that if any are changed the application will know what those folders are. I have tried to use a Custom action to write the config file but the install override does not seem to be called at all. If you write an override in an installer class, how and where is this called? I have looked at the Walkthrough for Passing Data to a Custom Action but the method never seems to get fired. Any help is appreciated.

    - Set Time Zone information Hi, I am trying to set the time zone information for a windows machine from a C# application. I have written a wrapper class for win32 api SetTimeZoneInformation and GetTimeZoneInformation. I am able to get all the time zones and the current time zone information. But when I try to set a new time zone information i see that the registry values get updated but the actual windows clock does not display these changes. I also broadcast the WM_SETTINGCHANGE message so all applications know about the changed time zone information, but with no effect. Also how to determine for whether it is daylight saving time from TZI byte values. Can anyone point me to documentation as to how to set the time zone in C# or give some suggestions. thanks in advance. Tag: Transaction code causing runtime exception Tag: 97333

    - Assembly loaded by a static (shared) function As I understand it, the only way to unload an assembly from memory is to load it in a separate appdomain and then unload that appdomain. However, I'm not sure about this situation. Here's the question: If an assembly is loaded by a static (shared) function, and no reference is maintained after that function returns, does the assembly remain in memory?

    - Reading the stream from a web response causes timeouts Hi, Im writing an application that crawls a website. One problem Ive come across is that sometimes, when reading the contents of a web response, the application will hang and timeout. This occurs when I am trying to read the stream returned from the GetResponseStream of the HttpWebResponse object. The code I am using is detailed below. I used the ReadFully method that Jon Skeet outlines on his website, just to be safe. http://www.yoda.arachsys.com/csharp/readbinary.html In the example below, I find that while I can download the file and view it using IE, when running my app, it frequently starts timing out after reading aprx 700kb - if anyone could suggest where I am going wrong it would be greatly appreciated.

Standard compliance is and will NEVER be important as getting it to work on multiple browsers, period. What good is standards if the app doesn't even work? How about a new standard?

    - Loading a referenced Framework 1.1 assembly from a Framework 2.0 Application Hello, We reference System.Messaging from our library that is a .Net Framework 1.1 assembly. This library is then referenced within our .Net Framework 2.0 Beta 2 application: Expected references: Application (2.0) ==> Custom Library (1.1) ==> System.Messaging (1.1) Now we have the problem that when the application starts, the framework loads our library and System.Messaging into its process, but System.Messaging is the version from Framework 2.0 and not the originally referenced from Framework 1.1. That causes our application to crash on dispose. Loaded references: Application (2.0) ==> Custom Library (1.1) ==> System.Messaging (2.0) Exception (thats the whole Exception): System.NullReferenceException: Object reference not set to an instance of an object. at System.Messaging.MessageQueue.MQCacheableInfo.Dispose(Boolean disposing) at System.Messaging.MessageQueue.MQCacheableInfo.Finalize() I have to say that we aren't able to move our library to Framework 2.0 (at least not yet), and with Framework 1.1 and Framework 2.0 Beta 1 there were no problems (maybe Microsoft changed the MessageQueue class from Beta 1 to Beta 2). Is there a way to force the Framework to load the originally referenced version? And shouldn't that be the default behavior? In our opinion it makes no sense that the framework loads by default the Framework 2.0 assembly even Framework 1.1 is installed and our library references the assembly from Framework 1.1. Shouldn't it load by default the originally referenced assembly and only if not found the new one? But thats a general problem, it has nothing todo with the System.Messaging; the framework always loads assemblies in this manner. Is this a bug or by design? We can create a workaround for this by adding a binding policy for System.Messaging but thats only a temporary solution, because we won't force every application to load System.Messaging from Framework 1.1. We use Framework v1.1.4322 and v2.0.50215. Any help or suggestions are realy appreciated! Regards, Stefan Born ___________________________________ Software Engineer bfa solutions ltd.

Here is the first method that works: Tlb file is added in references of VB project Dim obj As IMyAssembly Set obj = CreateObject("My.Namespace.MyAssembly") obj.DoSomething(); //working fine cheers! Here is the second method that doesnt work: Tlb file is not added in references of VB project Dim obj As Object Set obj = CreateObject("My.Namespace.MyAssembly") obj.DoSomething(); // doesnt work :( says 'Object doesnt support this property of method 'DoSomething'' I guess I need to supply the "default property" of object or "default interface" of object but i dont know how to do it in .NET C#. Any help on this will be appreciated. Fahad Ashfaque Tag: Transaction code causing runtime exception Tag: 97197

    - DataSet/datatable Dispose when dataset/datatable will be disposed ? After calling Dispose(), when i access DataSet or DataTable, the object exists. Even after calling GC.Colect(), when i access them, the object and data exists. Can anyone explain why & how. When i call dispose on dataset, will it automatically dispose all datatables that it contains ? thanks niranjan Tag: Transaction code causing runtime exception Tag: 97193

    - Assembly key files - one per assembly or one per entire application? This is a pretty minor issue but I'm wondering which makes more sense and why: Have one assembly key file per assembly or re-use the same key file for every assembly in the application? Does it really matter and if so, why? Tag: Transaction code causing runtime exception Tag: 97189

    - Release date and stability of .NET framework 2.0 (and VS) Hi all, I am planning a software project using C#. I expect the project to take at least two months of design and coding, and another two months of internal testing before it will be released. After receiving the Visual Studio 2005 beta 2 DVD and getting some experience with the new .NET framework, I am very pleased with the new features, so I am now considering to target the .NET framework 2.0 for this project and work with the new VS beta. One thing I could not easily find on the web is the expected "stable" date for .NET framework 2.0. As we are aiming to finish the project in 4 months, it is important for us to know if .NET 2.0 will be available for end-user installation by then. The same question I have about the release date of Visual Studio 2005. We have a small team and use techniques like version control; this would enable us to deal with most possible IDE disasters in VS. Also, I haven't triggered any bugs yet. Would it be unadvisable to use the .NET 2.0/VS 2005 Beta 2 combination for a serious project at this time? (A pointer to) some information about this would be appreciated a lot. Thanks!

    - .NET CLR 1.0.3705 difference cause MSIE downloaded problems? Hello, I am trying to resolve an issue where sending a file from a server to a browser using PHP will give an error message in MSIE, but the file does download from the server. The exact error is "There was an error opening this download. This file cannot be found". So far, all I've seen is that MSIE 6 using .NET CLR 1.0.3705 yields this message whereas our tests with .NET CLR 1.1.4322 work as expected. Is there a workaround for this other than forcing the user to update (and will the update solve it, i.e., is this a known issue)? Are extra headers needed with 1.0.3705 to send files for downloading with the proper disposition? Any other links to solutions or suggsts welcome! tia Tag: Transaction code causing runtime exception Tag: 97173

    - Terminial Server Help Needed!!!! Sorry for posting this again, but don't know where to post it so hopefully someone here will know more. Anyone knows how to find out how many instances of Terminal Server is running? If I have a Terminal server that has 5 licenses and 4 user's logon I want to know how to find out that 4 users are logged on. I'd like to do this all through code. Right now I am using VB.Net and trying to keep track of how many instances of my application is running. However, that does not work if the users logon with different usernames. Example: John logs on to the Terminal server with the user name John and runs HelloWorld. Then Mary logs on to the Terminal server with the user name Mary and runs Hello world. Normally you can check the Process ID of a running exe and see if it is already up before letting the program run again. This does not work when Mary logs on with her own username to the terminal server. Now if Mary logs on with the username John then try to run the application then the process ID code will tell her that another process is running. So I have two questions, how do I access details about a Terminal server through VB.Net? Is there something built in the framework of .Net for this? If there is something can that help me find the number of instance and what different user instances are currently running? Help would be greatly appreciated!!!!!!

    - Implementing enumerations that could change Hi Everyone, I have been designing a class that encapsulates the functionality of a "Phone Number". I find that I am getting stuck on how to implement the "type" of phone number the class represents. I started off by using an enumeration such as.. Enum PhoneType { Work = 1, Home = 2, Mobile = 3 } But as I thought more about it I wanted to be able to add more values to the enumeration as the need arose. It would be best if I could store the values of the enumeration in a database table. The problem is this: If I am thinking of changing the members of the enum, is an enumeration the best choice in the first place? I could use a class to represent the "Type" of phone but it almost seems like overkill to use a class just to enable the addition of future members of the "Phone Number Type". Can anyone suggest a better way? Thanks. -D Tag: Transaction code causing runtime exception Tag: 97158

    - How come Image.FromFile() member function is not avaiable? Hi, Refering to the title, I am using Visual Studio .NET 2003, WInXP Pro SP2 to develop C# on PocketPC. To me surprise, I cannot locate the member function, FromFile( ) from the System.Drawing.Image class. My VS only show 8 members functions from the class; (1) Dispose (2) Equal (3) GetHashCode (4) GetType (5) Height (6) Size (7) ToString (8) Width There are just no FromFile( ), thus I could not load a simple image into my picture box. Is it my .NET framework is not configurated or installed correctly? How am I going to know that? Please advise. I am really confuss. Tag: Transaction code causing runtime exception Tag: 97151

    - Getting initiating class name in its base class's shared property Hello, Is there any way of getting currently instantiated class name from a parent class's shared readonly property? I would need to know which actual class (that was derieved from the class containing the shared property) is trying to get the shared property value. It would be something like this: Public Class BaseClass Public Shared ReadOnly Property PageConfig() As PageConfiguration Get Return PageConfigurator.GetConfig( [here i would like a derieved class's name, if called through that] ) End Get End Property End Class Public Class DerievedClass Inherits BaseClass Public Sub SomeMethod() PageTitle = Me.PageConfig.Title End Sub End Class Why does it need to be Shared? I need to call it also for the derieved class from any other class that has nothing to do with the two above without creating an instance of derieved class, like: Public Class AnotherClass Public Sub SomeMethod Dim TargetUrl As String = DerievedClass.PageConfig.Url End Sub End Class Am I missing something? Is this possible at all? This is so trivially used in my projects and there are so many derieving classes that I would like to accomplish this task without needing to code anything in derieving classes. I've tried something with gettype and reflection without success. Any help appriciated, Pasi HÃ¤kkinen Tag: Transaction code causing runtime exception Tag: 97150

For some reason cannot open any file on local machine using window.open(...) command. Sample syntax : window.open("C:\\Downloads\\File.txt", "_blank"). This works on another development machine - Windows 2000 OS - with respective privilidges. Just won't open here - no error message - nothing. I've set permissions similiar to to Windows 2000 platform, ASPNET account for full control - but still won't open from laptop. Any suggestions? Tnks.

Hi,
I am currently trying write a windows form without much success to
implement an enterprise transaction that will encapsulate a write to an
oracle database, write a text file and then open a user control in another
windows form an collect a response from this.

I have been getting the following run-time error

'System.EnterpriseServices.SerÂvicedComponentException' occurred in
system.enterpriseservices.dll

then i stop the debug application and the following runtime appears at the
same point when i run it again.

A first chance exception of type 'System.IO.FileNotFoundExceptiÂon' occurred
in mscorlib.dll

followed by

A first chance exception of type 'System.ArgumentException' occurred in
mscorlib.dll

Additional information: Type passed must be an interface.

If i restart the machine i will receive the first error again.

I have added a strong name key to the application, also my actual class that
contains the transaction does nothing but open the trnsaction and then
complete it, but the class resides within the forms executable and not a
complied dll.

Any help would be greatly appreciated

Cheers D
