    - How to show a text showing the progress in percentage on a Progres Hi everyone I want to show the progress in percentage over a progress bar, like it is used in many of the installation programs, like if the background color of the progress bar is white and the text is showing "0%" then text is in blue color When the progress is "100%" the background color of the progress bar is blue, so I want the text showing "100%" should come with white color and when the progress is say "50%" then the background color of the progress bar will be half blue and half white, in this case I want the text showing "50%" should come as "5" in white color and "0%" as blue color, as if the text is showing the invert color of the background Is it possible?

    - Concise loading of data into a hashtable ? Hello, I am converting an app from JavaScript to ASP.NET I have the following JavaScript 'associative array'. Is there a concise way to create an analogous structure in .NET Framework using c# or VB.NET? I don't want to use JScript. consFin = {2:'m',4:'n',6:'ng',8:'r',10:'l',12:'kh',14:'k',16:'s',18:'hl',19:'tl',20:'s h'}; The amount of data is tiny and I have no wish to store it in the database. Likewise, I don't really want to use a pile of hashtable.add() statements to put the data to the hashtable. There are another 6 arrays of similarly sized data and 3 of them are associative arrays too. I could put this into 2-D arrays and have the data read into the hashtable but I would have to store the keys (numbers) as strings (and convert them, or not, to numbers) for my hashtable. Is this the most sensible solution? TIA. Tag: The specified domain either does not exist or could not be contacted Tag: 83705

    - Huge memory usage problem... Hello all, I have a windows form application which has a simple buttons toolBar, menuItem and a tab control with 3 tab pages each holding a treeView and a listView. When I checked to see how much memory usage my application demands I was surprised to see that even when the treeViews and listViews are empty my application takes about 25,000Kb (25M)!!! of memory usage! How can this be? Anyone with any idea as for what can cause such a thing? Just a simple comparison: Outlook 2003 which I understand is a .NET application takes up about 15M of memory usage and its obvious that this is a much bigger application then mine. I know its hard to help me without examining my application but it would help me a lot if someone would just throw a few ideas... Thanks, Haim.

    - How to intercept what HttpWebRequest sends? Hello everybody, I'm currently thinking about a way how to intercept the binary data that HttpWebRequest sends over the network. The class is a VERY helpful thing but there are a few things that I obviously can't do with it. In particular I'd like to have control over the header REMOTE_ADDR. I have server application that uses REMOTE_ADDR and other headers for identifying clients beyond cookies (which can easily be forged or stolen). For load tests I'd have to send requests from PCs with "different" internal IP addresses. As far as I know the REMOTE_ADDR is only for information purposes and is not involved in any low-level network routing and addressing. Anybody has an idea?

    - Negative Numbers? Hello, I have some textboxes that are doing addition: Dim AString As Double AString = Convert.ToDouble(TextBox1.Text) - Convert.To(DoubleTextBox2.Text) TextBox3.Text = AString.ToString("#,##0.00;(#,##0.00);0.00") When the result is negative it is displayed as "(46)" or whatever the value is. This makes it impossible to test for a negative number to make further additions: TextBox5.text = Convert.ToDouble(TextBox3.text) + Convert.ToDouble(Textbox4.text) Is there a work-around for this?

    - Forms inheritance best practice My application will have various forms for editing my business objects. All the objects to be edited on the various forms will either derive from a common class or implement a common interface. Let's just say it's an interface for sake of this discussion. There is a lot of common functionality between the forms, of course. Using forms inheritance seemed like a great way to reuse that common code. Of course there are some parts of the common code that need to interact with the interface, but the actual business object appropriate for the particular derived form will of course be instantiated by the derived form. The controls specific to editing that type of business object will of course be on the derived form. So, it seemed logical to create some abstract methods and properties in the base form. That means the class itself must be abstract. Not so fast - the designer complains it needs to instantiate the base class and can't because it's abstract. Hmmm.. That leaves me with two options that I can see. I'm just wondering which is considered a better practice, or if there's a third I haven't thought of. 1) Declare protected fields (of the interface Type) in the base form which could be set directly in the derived form in all the appropriate places. 2) Declare the needed methods and properties as virtual in the base class. In the base class each simply throws a NotSupportedException since only the override in the derived form should actually be used.

    - intranet and framework basics I'm trying to get a Windows Forms application to work on an intranet (not including my dev. comp.) It gives me the "unhandled exception error" so I found an article about strong names. I'm still lacking the basic knowledge of what's goig on when an application runs. First of all, does the server on which the application exists have to have the Framework installed or does the application run on the client machines? (What happens when they doubleclick the exe-file on the network share?) Once I copied the Strong name assemblies to the server I'm supposed to configure CAS Policy with custom code group, using Mscorcfg.msc. Where do I do that? On the Server or the Client machines?

    - method call only from "allowed" assemblies Hi, I was thinking of a "security concept" (- although it may already exist in the .NET Framework): to allow only some assemblies to call a method form another assembly... something like... a public method can be called by another assembly within an application but also by anyone from outside; this mechanism would check at method level/above method level who is calling and allow/disallow the call. Is this already implemented in .NET Framework? I would greatly appreciate some feedback on how this may be implemented (using StackTrace maybe)...

    - 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: The specified domain either does not exist or could not be contacted 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?

    - 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: The specified domain either does not exist or could not be contacted Tag: 83591

    - 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?

    - 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?

    - How to use LosFormatter from win form application? How to serialize and object to use as a parameter in a URL? Hi, I need to serialize an object in such a way that it can be passed as parameter in a URL http://www.domain.com?object=%d793btng.... I did some reading and I came to the conclusion that I need to create a custom formatter and implements the IFormatter interface the problem is that I don't quit know how to implements the IFormatter.Serialize function 1.How do I get the attribute of each property? 2.How can i get all properties,i guess I need to use reflection? 2.How do I track the object which already Serialized(assuming the object contains other objects) Note that I cannot use binary formatter or other,since the code which do the deserialization is a client side java script thanks in advance.

    - .NET Remoting problem - exception "Object Reference not set to instance of an object" Hi, I need some help with a .NET Remoting problem - an "Object Reference not set to instance of an object"exception is thrown in the client when accessing methods of a remote object. Basically, I have a server implemented as a Windows Service, using a config file, and implementing an object from the General namespace. The server code is below. ////Data definitions namespace namespace General { /// <summary> /// Interface to access data object /// </summary> public interface ICustomerManager { Customer getCustomer(int id); int getAge(int id); } /// <summary> /// Data object implementation /// </summary> [Serializable] public class Customer { //put all functions in an interface protected int cust_id; public string firstName,lastName; public DateTime BirthDate; public Customer(int id) { cust_id = id; } } } /////////Server code namespace WindowsServiceSrvr { public class ServiceSrvr : System.ServiceProcess.ServiceBase { private ComponentModel.Container components = null; public static string SVC_NAME = "ServiceSrvr"; public static string cfgFile = "server.config"; public ServiceSrvr(){...} static void Main() { System.ServiceProcess.ServiceBase[] ServicesToRun; ServicesToRun = new ServiceProcess.ServiceBase[] { new ServiceSrvr() }; evt.Source = SVC_NAME; ServiceProcess.ServiceBase.Run(ServicesToRun); } protected override void OnStart(string[] args) { RemotingConfiguration.Configure(cfgFile); } } [Serializable] public class CustomerMgr : MarshalByRefObject, General.ICustomerManager { public CustomerMgr() { } public Customer getCustomer(int custId) { General.Customer cust = new Customer(custId); cust.BirthDate = new DateTime(1945,12,12); return cust; } public int getAge(int custId) { General.Customer cust = this.getCustomer(custId); TimeSpan tmp = DateTime.Today.Subtract(cust.BirthDate); return (int)tmp.Days/355; } } } My client uses a Generated_General.dll generated by soapsuds soapsuds -url:http://localhost:custSrvr?wsdl -oa:gen.dll The client code is: namespace ClientUsingService { /// <summary> /// Implementation of client - config file, soapsuds generated /// metaschema, and a server running as a windows service /// </summary> class Client { public static string cfgFile = "app.config"; [STAThread] static void Main(string[] args) { try { RemotingConfiguration.Configure(cfgFile); // Instantion CustomerMgr interface WindowsServiceSrvr.CustomerMgr custMgr = new WindowsServiceSrvr.CustomerMgr(); if(custMgr!=null) Console.WriteLine("Got server connection"); General.Customer cust = custMgr.getCustomer(5434); Console.WriteLine( cust.BirthDate.ToShortDateString()); // throws Invalid Reference Exception Console.WriteLine("Customer 5434 is {0} yrs old",custMgr.getAge(5443)); Console.ReadLine(); } catch(Exception ex) { Console.WriteLine(ex.Message); Console.WriteLine(ex.StackTrace); Console.ReadLine(); } } } } The problem is that when the methods of custMgr are called by the client the exception "Object Reference not set to an instance of an object" is thrown.

    - 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?

    - Activator.CreateInstance with implicit type conversion Hi, I've got a class constructor that takes public Foo(int a, MyString b) MyString type has an implicit operator for string so I can call this from code with Foo f = new Foo(1, "hello"); However i'd like to programmatically call the constructor using Activator.CreateInstance(typeof(Foo), new object[] { 1, "hello" }) This doesn't work because the constructor is of type MyString, and the CreateInstance Binder is looking for a type string. Is there anyway to get the Binder to just 'use' the params I pass in, or at least to see if there is a possible implicit type conversion possible???

    - 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: The specified domain either does not exist or could not be contacted Tag: 83511

The code runs successfully on a fresh install of Windows Server 2003 in a
native mode domain of Windows 2003 domain. But it fails on Windows 2000
Server in the same domain or a Windows Server 2003 upgraded from Windows
2000 Server in the same domain. The error message is:
