    - HTTP violation Hi I've made a part of a program that makes a http web request with .net classes HttpWebRequest and HttpWebResponse. It's been working fine up til now when one of our customers has been recieving the following WebException: "The underlying connection was closed: The server committed an HTTP protocol violation. " I've been "googling" a bit and read that it might help to set the KeepAlive property to false and set the http version to 1.0, but neither have helped. Thanks in advance! /peter Tag: timeout to NTD winform Tag: 83617

    - Repeater Problems in Framework 2.0 Hi, Quick Question. I am having problems with nesting repeaters in the Framework 2.0. The code below works in framework 1.0 & 1.1, but does not in 2.0. The inner repeater does not appear to bind properly. I am using the Visual Web Developer 2005 Express Edition and the framework which is downloaded with it (downloaded 2 days ago). Can anybody let me know if I am doing something wrong or is this a bug? Thanks in advance.

    - Key processing in .NET Is there any good article about processing keys in .net ? I see things like ProcessDialogKey, IsInputKey, IsInputChar, and mentions of preprocessing certain keys, and the whole area is confusing to me without a good general explanation. In Win32 I can override WM_GETDLGCODE in my derived control to handle certain dialog keys directly in my control ( arrows, tabs ). The documentation on processing keys which I am trying to understand does not make it plain how I can use the .net functionality to do what I want to do rather. I realize that I can continue to handle WM_GETDLGCODE in my control's Window procedure but would prefer to use the .net functionality instead if it is a replacement for the lower level WM_GETDLGCODE Tag: timeout to NTD winform Tag: 83597

    - Design issue with O/R mapping Hi. Im have asked for recommendation regarding the best production ready O/R mapping tools for .net. I got that. Since im an old, ok maybe not old (only 27), Java programmer patterns and developement with tiers is of great importance for me. I have a problem with the famours anti-pattern Tier leakage. In the Java world I used POJO´s (simple java classes) as value objects. These value objects was used for cayrring data between the tiers. So if i changed the persistence tier the rest of the code still relyed in the same POJO´s. Now with the .net O/R they all genereate eg. EmployeeEntity wich inherit from EntityBase2 (LLBL PRO). If I pass the object from my persistence layer to the business layer and down to the view I have just made a seriuos "maintaince bug" the "tier leakage". If i wanna use eg. the EntityBroker im so to say fucked. I have to refactor ALL and EVERY class witch depend on the EmployeEntity. Have anyone thougt about this and come up with an solution? Is the persistence tools wich can map PURE c# classes to realtionel classes as the Java Hibernate? And why have so few chosen this way of doing it? Is it hard to map eg. Customer c = new Customer(); // fill object adapter.SaveEntity(c); And go find what this Customer really maps to int the Database? Anders Jacobsen Tag: timeout to NTD winform Tag: 83592

    - Method RVAs: offset or VA? Greetings, I'm writing an application that uses the Profiler API and the unmanaged metadata API to obtain metadata for modules from the ICorProfilerCallback::ModuleLoadFinished() event as well as for executables that I map into memory myself. In both cases I'm able to obtain the IModuleInfo iface and enumerate the methods. I've noticed that the method RVA returned by GetMethodProps() is sometimes a real RVA and sometimes an offset. This causes havok because I'm trying to access the method's bytecode in memory. If its an RVA I have to call ImageRvaToVa(), otherwise I just have to add it to the base load address. It seems to be treated as an offset if the CLR has loaded the module and as a RVA if the file was manually mapped into memory. Is this true? Strangely, Rotor always treats it as an RVA. If you look at CorMap::ReadHeaders() in cormap.cpp in Rotor you'll see a magic flag called bDataMap that proves that RVAs have a dual nature. Right now I have a kludge that calls ImageRvaToVa() and examines the first byte of the returned ptr. If its not TinyFormat or FatFormat then I treat the RVA as an offset. Is there a way, given a module's base load address, or perhaps a flag in the MethodProps, to determine if its RVAs are really RVAs or if they are offsets? Thanks! \\Marc Tag: timeout to NTD winform Tag: 83591

    - Calling Dispose instead of close, clear, .... Hello, I've written the following little helper function which calls Dispose on classes which implement the idisposable interface. Public Sub DisposeObject(ByVal DisposeAbleObject As IDisposable) If Not DisposeAbleObject Is Nothing Then DisposeAbleObject.Dispose() End If End Sub The reason for this is to avoid ugly looking finally clauses with lots of checking if an object ref is nothing before calling dispose on them. For example in a try finally block in which a connection is opnened, a transaction is started and an sqldatareader gets created which looks like this: try ..... finally if sqlconnection is nothing then sqlconnection.close end if if Transaction is nothing then Transaction.dispose end if if Datareader is nothing then Datareader.close end if end try i'd write this: try .... finally disposeobject(sqlconnection) disposeobject(transaction) disposeobject(sqldatareader) end try a lot better looking IMO. I dont have to worry about whether the ref is nothing or not. Now my question is this: Is this going to cause any strange behavior? I've tested it and it seems to work.. but im wondering if there could be any side effects since im not calling the specific Close of the datareader or sqlconnection, im calling the Dispose. The documentation says there's not much difference in calling Dispose instead of Close on a connection, but can i assume the same for any object that implements IDisposable?

    - Windows DataGrid client area is not redrawn after grid is refilled Hi, I have a problem with Windows forms datagrid control. This problem appeared only after I have installed .net framework 1.1 service pack1. Basically after grid is refilled either with new datatable or a view derived from that datatable I can see a gray cell on the client area of the grid if grid is empty (meaning that underlying datatable did not have any rows). If on the other hand grid is refilled with some data I can see a cell that was definitely left over from previous datatable. I suspect that when Microsoft released sp1 they messed up something in internal implementation of paint capablities of the grid control. So, my question is this. How can I remove service pack 1 of .net framework 1.1 and return framework to the original state? Thanks in advance Tag: timeout to NTD winform Tag: 83554

    - Performance counter installer breaks service installers? Hello, I ran into a strange problem related to performance counter and service installers. I created a windows service using C#, VS.NET 2003 and framework 1.1 SP1. Everything went smooth and I got the service up and running. Later, I added some performance counters to the service by dragging them from the toolbox to the design view of the service. I set the properties of the counters, and created installers for the counters. When it was time to deploy the service, the problems began. "InstallUtil MyService.exe" executes smoothly without exceptions. But the services MMC-snapin shows no startup type for the service. Clicking properties or trying to start the service results in an error message "The system cannot find the file specified." After some investigation, I noticed that if I remove the performance counter installer calls from the code generated by Visual Studio, service installation works again. This led me to investigate the differences in the registry after installing the service with the two variations. When the performance counter installer calls are present, the HKLM\SYSTEM\CurrentControlSet\Services\MyService key contains no values. However, when I remove the performance counter installer calls, the same key contains the following values: ErrorControl, ImagePath, ObjectName, Start and Type. The service also starts just fine, and its properties are available through the Services MMC snap-in. The logical conclusion is that the performance counter installers break the install process, even though there are no error messages. Any suggestions how to fix this? -- Jussi Isotupa CTO jussi@weppihiiri.fi.NOSPAM Weppihiiri Ltd. http://www.weppihiiri.fi/ Tag: timeout to NTD winform Tag: 83511

    - .net Framework 1.14322 I am receiving an error message each time I run various apps, including any Help files. . It reads: .net framework initialization error. To run this application you must first install one of the following versions of the .net framework: v1.1.4322 and v1.0.3705. I have 1.1.4 installed, there's even a folder named C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322 I even get this error while trying to install MS files I downloaded to try to solve this problem, such as NDP1.1sp1-KB867460-X86.exe. This can't be related to any one service that I downloaded, as it occurs in a number of different situations. It pops up in MSN Explorer, when trying to install MS software as noted above, and other areas. Someone please figure out why?? I'm running Win ME, by the way. MSIE 6.x.

    - Strongly Typed Collection Problem Hi All I have a class Persons that hold key/value pairs of Person class. My problem is the following. On the first screen I create an instance of Person, I then add a name and surname and then add the class to class Persons ( I can add more than one Person class on this screen). On the next screen I retrieve the Person I am interested in and add Home Address or whatever I wish to add. The problem starts when I call the Add method of the Persons class. The value (Person that's been updated) is never stored or updated in the Persons class. public object Value { get{return this.mValue;} set { if (this.mValue != value) { this.mValue = value; } } } Can some give some green light?

I am not using a password to generate the Key and IV, but am just hard-coding those values into the class. Yes, I know, but I intend to build on it later for better security.

    - Getting an array of structures from Win32 API calls I have a small chunk of Managed C++ code that is attempting to call into an umanaged Win32 api to retrieve a list of structures. Unfortunatly, I'm not having any luck getting this code to work. Any help would be appriciated: I'm defining the pointer that will hold the array of structures as: GROUP_USERS_INFO_0* pstUsers = NULL; The actual API call looks like: status = ::NetGroupGetUsers(server, unmanagedGroupname, 0, (LPBYTE*)&pstUsers, MAX_PREFERRED_LENGTH, &dwEntries, &dwTotal, &dwResumeHandle); I'm getting sensible results back for the dwEntries and dwTotal fields. I then try to parse out the group names: StringCollection* results = new StringCollection(); for (DWORD i = 0; i < dwEntries-1; i++) { System::String *s = System::Runtime::InteropServices::Marshal::PtrToStringUni(pstUsers[i].lgrui0_name); results->Add(s); } Much to my annoyance, my string always ends up with garbage in it. I'm not to familure with Managed C++, so I'm probably doing some very obvious wrong, but I'm not making too much progress... (I can't use the DirectoryServices for this, as I'm talking to an NT4 Domain rather than AD, and this particular method isn't supported...) -- Chris Mullins Tag: timeout to NTD winform Tag: 83482

We would like to be able to package it up onto a CD so that someone could run it on their laptop that doesn't have internet access or even a web server on their laptop. So we would like it to run basically like an EXE without a web server. Is this possible? Are there companies that sell a conversion tool like this? thanks in advance.

    - Use reflection to call base class implementation of virtual method I'm trying to use reflection to lookup and invoke a specific instance of a virtual method on a class. I can get the method easy enough, but the Invoke method of MethodInfo states that it calls the correct virtual method based on the passed in instance type. The problem is it doesn't point out a way to invoke a specific instance of an implementation in the inheritance hierarchy. I'm essentially attempting to invoke the base.MyMethod through reflection, but can't find any way to do so. Any ideas? Tag: timeout to NTD winform Tag: 83448

Done some testing and find them hard to work with. AIm I really wrong here? Is ADO.NET defacto to use in dot.net today and I am the one not undestanding the brilliance in ADO.NET?

I am sure that I am not the only one that has had this issue. Or is it because I used a dirty N word. "Novell" Here is my previous post. I really hope someone can help with this because I don't know what else to do. Abandoning Novell is simply not an option at this point. UnauthorizedAccessException when trying to access a Novell network drive. The code is very simple. This is the line that fails when trying to create a new StreamWriter where _filename is a string that points to a Novell network drive. StreamWriter file = new StreamWriter(_filename,false); The user has full access to the directory. By the way. This line works fine on the local box as well as accessing a Windows NT 4.0 or 200x Server drive. This issue is only with Novell Drives. The client is Windows XP SP2 using the native Novell client drivers that came with XP. I have not yet Tried the Novell Client Drivers from Novell. Any help would be greatly appreciated.

    - Debugging in IIS My co-worker and I can not seem to set up our IIS environment to allow debugging if we are both working on projects. The server is win2K sp4, IIS 5, ASPNET version is 1.1, Visual Studio is 2003. Our working directory is on the "D" drive in a folder called ASP_Net_Projects and we have made this folder the home directory of our default website in IIS. We are both members of the debuggers group, and that group has full control of our working directory. We still get errors when we are both debugging. The error is that there is another instance of the debugger running and the machine can not start another. Any advice or guidance would be greatly appreciated. Thank you.

    - Where can I find a design pattern for paging through a list? Hi, How do websites like google page through large numbers of records? For example; if I do a search on Google, get 187,000 matches, and go to the 22nd page of the results; I'm sure Google doesn't do a new SELECT statement and traverse through 440 records (22pgs x 20 per page). But I'm also pretty sure Google doesn't keep a hell of a lot of session data open either. I know there are all kinds of ways to do this, I've created hacks which did the job in the past. But there has to be a 'best practice' way of handling this. Can anybody point me in the right direction? I'm open to technology specific ways, but would prefer generic.
