    - C#, or third part sql Database Hi group I need a SQL database in my application, and i need i can sell it with the app. It have to supports thousands of enregistrement in few table not related. It don't have to be extremely efficient, or multi utilisators There is no extreme specs. It have to be intregrated in my app. My questions are : - is there a C# native SQL database (or something ?) - do you know abou third part (chip by préférence) SQL database, wich could be what i need ? - do you think i can reasonably play with XML file to simulate a database ? - others ideas ? please don't search for me i don't want to waste time (mine nor yours) just, if you allready know response to my questions give me it. thanks you for your tips guys :) ROM Tag: assembly reference lost (after uninstall).

    - Problem in using COM object in .NET Hi all, I have written a simple COM object in ATL, one of whose methods is: STDMETHOD(Write)(/*[in]*/BYTE *buffer, /*[in]*/long count, /*[out,retval]*/long *bytesWrite); I have implemented the method as: STDMETHODIMP CMyControl::Read(BYTE *buffer, long count, long *bytesRead) { AFX_MANAGE_STATE(AfxGetStaticModuleState()) // TODO: Add your implementation code here strcpy(buffer, "this is a test"); *bytesRead = count; return S_OK; } The problem is when I try to use it in .NET framework (using C#) like this: byte[] buffer = new buffer[25]; int count; IMyControl mc = new MyControlLib.CMyControl(); mc.Read(ref buffer, buffer.Length, count); I am getting following error: 1. The best overloaded method match for MyControlLib.IMyControl.Read(ref byte, int)' has some invalid arguments 2. Argument '1': cannot convert from 'ref byte[]' to 'ref byte' Please tell me how can I resolve this issue. Thanks, Arsalan Ahmad Tag: assembly reference lost (after uninstall). Tag: 69650

    - simple .NET DHCP solution? Hello, I am working on a system of distributed robots running XP Embedded all communicating over an ethernet TCP/IP network. This distributed system should allow: - robots to be added and removed from the network at any time - allow auto configuration of networking parameters so robots can dynamically join and leave the network without user intervention My problem is (one of them anyway) that I can't have an external DHCP server box on the network, so the robots themselves need to work out IP addressing conflicts. I'm trying to figure out the best way to do this using C# and .NET technologies (if possible). Static IPs won't work because the robots can't be configured before hand. They all must be running an identical software configuration on startup. Initially I was thinking of hosting a DHCP server on each machine, and having the first machine on the network declare itself as the DHCP server. Subsequent robots joining the network would then see that a DHCP server is already on the network and become a client rather than a server. If the robot hosting the DHCP server leaves the network, through some random selection process another machine would take over DHCP responsibilities. This has some complications since every machine would have to know which addresses were already leased out so when a new DHCP server takes over, it can continue without problems. However, I can't find any free windows DHCP implementations around (in c# or anything else for that matter) that I can hack up to do this. Besides, this solution seems kind of bulky because DHCP has many more features than I need. Next I was thinking about perhaps implementing a simple address resolution protocol using the .NET sockets API. Mabye a protocol that would have all machines broadcast all current MAC address to IP address mappings, and allow individual robots to decide their own ip addresses based on the current known mappings. I feel strange about implementing an address resolution protocol though, since its totally reinventing the wheel. So my question is, does anybody know of a better way to do this? Am I aiming in the wrong direction here? Does this question make sense? Thank you for any ideas! -Jim Tag: assembly reference lost (after uninstall). Tag: 69646

    - SmtpMail hell I keep getting this message when I try to send mail with SmtpMail: "The message could not be sent to the SMTP server. The transport error code was 0x800ccc64. The server response was 502 Unknown command" When I look in the mail server's log, the last thing it processes is the command "SATA", then it 502's. When I run the app locally, on my development machine, with a different SMTP server, all is well. The server is Windows2000, all the latest updates. The mail server is ArGoSoft, which has authentication enabled, but the WebServer IP address is trusted. Oh, one other bit of wierdness, when I use the same SMTP server as on my dev machine, it gets the same error, but specifically states, "502: command SATA unknown", the web server and my dev machine are both on the same network (RR), so I expected this to work. Any help would be great... Jeremy Tag: assembly reference lost (after uninstall). Tag: 69645

    - Threads and asychronous operations.. how are they different Hi: I have a couple of questions about threads and asynchronous calls Question 1: How are these two different? Situation a: Caller calls method1 with parameters Method1 takes parameters from caller, creates an object with those parameters passed in to be stored by the object as member variable, calls a thread method on the object, starts thread and returns. Situation b: Caller calls method2 with parameter Method2 takes parameters from caller, creates async delegate for a method in its class, calls asynchronously the method, giving it a callback function with the delegate as the last argument and returns. when the async call is complete, it calls the callback function which takes the delegate object passed to it and endinvokes it. Question 2: If two different delegate wrappers for the same method are called back to back, will they run concurrently on the system, or does the second method call have to wait for the first one to finish before executing. Of course for this I would pass in a callback function that would handle the endinvoke. In that way, at least from the outside, it would look like they behaved like threads. But what about internally. Would they truly behave like threads? For my situation, if they behaved exactly like threads, it would be very beneficial to me. I find greater flexibility with asynchronous calls because I can pass in parameters. Of course, if I created objects to do my work in a thread, I could give it parameters to hold as member variables, but that would require creating an additional object. But if I wanted to use a class method to do the work, using a thread would prevent me from passing in parameters. With async calls, I can pass in a reference parameter, which could be modified by the async call. I could then check the state of the reference parameter. In this sense, I can pass in parameters and get return values (could also just use an out variable). Question 3: If a delegate is passed to a function as a ref parameter, and it has a method that can be threaded, can that method be threaded by the function and let to do it's work. And if so, if thread modified its object's state information, would those changes be seen by the original object passed? If both caller and function are in the app domain, it really isn't that important to me? But what if they are in different domains? For example, what if the caller is using a remote object, and passing in a delegate object that will be threaded on the remote machine. In which domain is the thread running? Answers to these questions will be greatly appreciated and will help me in my understanding of multi-threading in C# and .NET Steve Tag: assembly reference lost (after uninstall). Tag: 69640

    - Workflow in ASP.NET ? Hi. I asked this one before without any response, but I'll give it ago. In Commerce Server they have a pipeline editor which runs a series of components, the main drawback is that it doesnt support strong names or any web-interface programming, so changes need to be made from the admin utility. Surely its possible to create a workflow component in VB.NET where you can get this to call specific functions within a list of assemblies using reflection or IDispath, the only other problem is it has a scriptor component that allows you to use VB script, how would this be compiled on the fly and you would also need to pass an object to the script function. Any ideas ? Thanks Paul Tag: assembly reference lost (after uninstall). Tag: 69631

    - Component constructors, is there another one ? In the Writing Components topic of Mr. Grimes' book on Managed C++, he states that if a component is ultimately derived from either MarshalByRefObject or MarshalByValueComponent, it should implement a second constructor which takes an IContainer in order to add itself to a component container. While I understand that components have containers, I have seen no documentation regarding a second constructor to a component. Does it really exist or is this an error in Mr. Grimes' nearly flawless technical writing. If this second constructor actually exists: 1) What container(s) creates a component calling this second constructor ? 2) Why does MarshalByRefObject or MarshalByValueComponent not have this second constructor which would automatically add itself to an IContainer derived object when a derived class calls down to one of these bases in its constructor ? 3) Where in the MSDN documentation is this second constructor documented ?

    - Why does a call to a function in a dll take less time if you call it repeatedly? Could explain how the .net assemblies (Dlls) work when they are used by an exe -- I'd much appreciate it. If your exe is making a call to a function that's part of the .net framework library (ie System.Math.Ceiling), the amount of time taken up on the first call to the specific function is usually about 80-90% more than when the function is called again. Can someone explain to me why this works as it does? I know that when you use a Dll, it's got to get loaded into the system and map all of proc addresses for the functions into memory. On the first call, are these mapping of the function to a particular location in memory left blank and is the majority of time spent filling in these mappings? This brings up the question of whether there is a way to load the Dlls you're going to use for a certain EXE and set it up so everything is pre-cached? Is it possibly a setting for your project in Visual Studio.net? Apologies if this sounds vague but I'm not entirely familiar with this stuff just yet.

    - Memory leakage while using ActiveX DLL I am struggling to figure out the cause of an out of memory exception I am getting involving the use of an ActiveX DLL. About three years ago, I developed an ActiveX DLL (called TFile.DLL below) using VB6, and have since then invoked it successfully in other VB6 ActiveX DLL projects. Last year, I developed a web service with VB.NET where I used this DLL too. The main code is in a web method, whose logic is basically like this: ___ Try ... TDocument = New TFile.TDocument mOraDynaset = CType(mOraDatabase.CreateDynaset(strQuery, dynOption.ORADYN_NOCACHE + dynOption.ORADYN_READONLY), OraDynaset) mOraDynaset.MoveFirst() Do While Not mOraDynaset.EOF TF = New TFile.TF With TF TDocument.A = ... ... TDocument.L = new TFile.L TDocument.L.L1 = ... ... End With TDocument.Write(TF) TF = Nothing mOraDynaset.MoveNext() Loop Catch ... _________ This web method code has been working great. Task aspnet_wp.exe does not show any sign of memory leakage. Now I have migrated this code to a .NET class library. The code structure has remained basically the same as shown above. However, during execution, there is a gradual leakage of memory eventually leading to an out-of-memory exception. I have placed Marshal.ReleaseComObject calls for all the COM objects, but they don't seem to help. Can anybody see any reason why this is happening and offer suggestions to eliminate the memory leakage? TIA. Tag: assembly reference lost (after uninstall). Tag: 69621

    - ASN.1 Encoding/Decoding in .NET? Hi, I'm developing an OCSP (Online Certificate Status Protocol) responder with the .NET framework and C#. The protocol for communication is defined in ASN.1 rules and DER used for encoding/decoding of requests and responses. Unfortunately, I was not able to find any class libraries for encoding and decoding of DER messages in the .NET Framework. I checked the CryptoAPI library, but there are only routines for encoding/decoding of x509 certificates or PKCS#7 requests. Probably I'll need a multi-purpose ASN.1 routines. Any idea?

    - file not being released in a timely manner I've written a vb.net webform based application. It uses CDO and it runs through a list of database records and for each record, it creates a new email object, attaches a single file, and then sends the message. I use message.AddAttachment(AttachedFile) to attach the file. After I've sent the message I copy the the file that was attached to the message to a backup directory. I then delete the file. The copy is instantaneous. However, it can take quite some time before the file is actually deleted. It varies between a couple of seconds and more then a few minutes. If I close the application, the file disappears within a few seconds. I believe that the email object is holding onto the file until Garbage Collection completely reclaims the email object. I've added GC.Collect right after the email is sent and after I've set the email to nothing. It speeds up the deletion but not in a predictable manner. What's the best approach to speeding up the reclamation of the email object so that it releases the hold on the file? Do I have to take into account that the email object is created using CDO? Is the CDO library considered unmanaged and if it is does that complicate the disposal of the email object? Thank You, Eric Tag: assembly reference lost (after uninstall). Tag: 69599

    - ANN: Galois.Net Hi, I have posted recently a similar message, I believe it is particularly interesting for people with a mathematical background. Also, the whole application was developed with .Net Framework SDK only. The beta version of Galois.Net is now available for download. Galois.Net is made of two parts: the Galois Knowledge Environment and a collection of Xml tags. The Environment is used to create and share theories presented using the Xml tags. You can download it at: http://www.a2ii.com/galois/index.htm More information about Galois.Net can be found below. Daniel Perron, Ph.D. Lead Developer Galois.Net ========================================================= XML specifications for .Net components The Visual C# compiler has an option switch that extracts the comments within the source code of the program being written if the comments follow a certain XML syntax. This simplifies the generation of reference documentation for the application. Java compilers also have such a facility and we can probably trace the original idea behind such a feature to the proposal for Literate Programming made by Donald Knuth in the 80's. In this note, we would like to extend these ideas using custom attributes provided by the .Net Framework. We'll start by defining a custom attribute named Galois as follows: using System; namespace Galois { [AttributeUsage( AttributeTargets.All, AllowMultiple = true )] public class GaloisAttribute : Attribute { string theory; public string Theory { get { return theory; } set { theory = value; } } public GaloisAttribute( string thm ) { theory = thm; } } } We have created a namespace for this attribute and the attribute itself has only one read-write property Theory of type System.String. You can compile this code and reference it in your application. The Theory property of every Galois attributes will be an XML string with tags chosen to allow specifications in a certain logic, namely geometric logic. Geometry logic has nice mathematical properties (the class of models of a given theory constitutes what mathematicians call a topos). For example, we would like to attach a Galois attribute to an interface that will be used in every Windows.Forms program that use a menu as follow: using Galois; public interface GTMenu { [Galois(@" <co a1='p' t1='Program' a2='m' t2='Menu' a3='s0' t3='Statement' a4='s1' t4='Statement' a5='s2' t5='Statement' > <if><pr n='Uses' a1='p' a2='m'/> </if> <tn><te a1='a' t1='Array'><pr n='ElementType' a1='a' a2='Statement'/></te> <pr n='GetValue' a1='a' a2='0' a3='s0'/> <pr n='Equals' a1='s0' a2='MainMenu.ctor'/> <pr n='GetValue' a1='a' a2='1' a3='s1'/> <pr n='Equals' a1='s1' a2='MenuItem.ctor'/> <pr n='GetValue' a1='a' a2='2' a3='s2'/> <pr n='Equals' a1='s2' a2='AddEventHandlerForClick'/> </tn> </co> ")] void SetupMenu(); } Let's look at the interface itself first. The interface is named GTMenu (for the Galois Theory of Menu) and it contains only one method SetupMenu() (note also, the "using" statement at the beginning to be allowed to use Galois custom attributes). The Galois attribute itself is attached to the method SetupMenu of the interface. The string that is passed to the attribute starts with the @ sign so we can break the specifications on multiple lines and we use ' (a single quote) inside the string to delimitate the XML attributes of the Galois.Net elements that we are now going to describe. The top-level element of the XML string is <co a1 ...>. The "co" element of a Galois attribute defines a context which is a list of variables names and theirs types (as in a1='p' t1='Program' for the variable p of type Program). Inside this context element, we have an "if" element for the "if" part of a rule and "tn" element for the "then" part of a rule. Galois.Net specifications are made up of contexts that define the variables used in the rules. Inside the "if" element or the "tn" element we can have relations (or predicates). In the specification above, we have inside the "if" element, the relation Uses which is written as the element "<pr n='Uses' a1='p' a2='m'/>" which says that "if the program uses a menu then ...". Then what? The specification says that there exists an array of statements whose first member is a MainMenu constructor, second member is a MenuItem constructor and the third member is the statement 'AddEventHandlerForClick'. The "te" element states that "there exists" a variable of type Array. The specification also uses the predicates "GetValue" which is true if the value of the object at position, say 0, is s0. Galois.Net specifications treat a function as a relation that defines its graph. And if the function is a method then its first argument will be the name of the given object (just like when the pointer "this" is passed to a function in a given implementation of a compiler for an object-oriented programming language). This specification can be displayed (in the Galois Knowledge Environment) as follow: Context: For All p: Program, m: Menu, s0: Statement, s1: Statement, s2: Statement, IF (rule #1) Uses( p, m ) THEN THERE EXISTS a: Array ElementType( a, Statement ) GetValue( a, 0, s0 ) Equals( s0, MainMenu.ctor ) GetValue( a, 1, s1 ) Equals( s1, MenuItem.ctor ) GetValue( a, 2, s2 ) Equals( s2, AddEventHandlerForClick ) We can conclude that this context defines a language with: 4 sorts (Program, Menu, Statement, Array) 3 predicates (Uses,ElementType, GetValue) where Uses < Program x Menu (we use < for the subset relation) ElementType < Array x string GetValue < Array x int x Statement the constants 0, 1, 2, MainMenu.ctor, MenuItem.ctor, AddEvenHandlerForClick, and a geometric theory with a single axiom. Any interpretation (or model) of this geometric theory will involve assigning "universes" for the different sorts. Usually these universes are just plain sets, but generally, they can be taken to be objects in any given topos. Then the predicates will be subsets of the appropriate product of sorts and the constants are elements of the sets that represent the given sorts. The values for the statements in the above specification i.e. MainMenu.ctor, ... were chosen to reflect the knowledge that would be needed to implement a menu in a Windows.Forms application. A program that implements the GTMenu interface with its Galois attribute could be written as (when compiling, remember to add a reference to GTMenu.dll compiled earlier): using System; using System.Drawing; using System.Windows.Forms; class CreativeGL : Form, GTMenu { public void SetupMenu() { Menu = new MainMenu(); MenuItem menu = new MenuItem( "A menu" ); Menu.MenuItems.Add( menu ); MenuItem miOne = new MenuItem( "One Item" ); menu.MenuItems.Add( miOne ); miOne.Click += new EventHandler( miOneHandler ); } public CreativeGL() { SetupMenu(); } public void miOneHandler( object o, EventArgs ea ) { MessageBox.Show( "You clicked the menu item" ); } public static void Main() { Application.Run( new CreativeGL() ); } } This is just a test program but it shows an important idea: A program can be seen as a model for the theory specified in the Galois attribute (of the interface that is implemented by the program). A more detailed specification makes it easier to associate values to symbols in the specification i.e. to define a model. Because the tags of the Galois attributes were chosen to express specifications in geometric logic these remarks can be made formal. As a simple consequence of this formal theory, a "bug" has a nice interpretation in this setting: since a rule in a Galois specification essentially represents the claim that an abstract geometric object is contained in another one, a bug is a point of the smaller object which is not covered by the "bigger" one. Creating components with Galois attributes wouldn't be very interesting if we were not going to exploit this extra information contained in the specification. Luckily, the .Net Framework makes it very easy to extract custom attributes from components. The Galois attribute used above was written to express the minimum information needed to create a Windows.Forms with a menu (we could make it more precise to include the information that we need to add the menu item to its container). Similarly, the same approach could be used to express the minimum information needed to created a client network application, a server network applicaton etc... And more generally, we can use Galois specifications to make explicit the information that programmers assumed when they are writing their code. This way, we could extract all the theories contained in all the code written by a given programmer and treat this as a representation of his/her expertise. Going one step further, we can imagine a programmer displaying this representation in the form of a Web service that is used to "contract out" this expertise. We believe that custom attributes, as used with Galois.Net to specify components, fill an important gap in providing a nice semantic for component-based software development.

    - Assemblies for custom component not loading Hi all, I've got a solution containing several projects for some components I'm trying to develop: A, B, C A inherits from System.ComponentModel.Component. Its purpose is to house some base functionality for my suite. B inherits directly from A and does it own thing. Likewise C is a more specialized component of type B, so it's inheriting straight from B. Compilation goes fine and all three resultant dll's are in C's bin\debug folder. So we have A.dll, B.dll and C.dll all in the same folder. I then added a registry key for the AssemblyFolders key with this output as the default value for the key. Reopen vs.net and my components (all called Class1), are showing up in the ".Net Components" box when you click the Add/Remove context menu. I put C on the toolbox.. drag and drop it on the form and nothing is placed on the component tray. I used fuslogvw to log assembly binding and got entries for A and B: *** Assembly Binder Log Entry (2/19/2004 @ 4:03:27 PM) *** The operation failed. Bind result: hr = 0x80070002.

    - WSDL generates array rather than data type In generating a proxy using WSDL, a collection type I have defined is transformed into a simple array. This later causes data to not be passed correctly in the web service client. Here's a partial example: <xs:complexType name="MyResponse"> <xs:sequence> <xs:element name="MyList" type="MyList" minOccurs="0"/> <xs:element name="OtherData" type="xs:string" minOccurs="0"/> </xs:sequence> </xs:complexType> <xs:complexType name="MyList"> <xs:sequence> <xs:element name="MyListDetail" type="MyListDetail" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> <xs:complexType name="MyListDetail"> <xs:sequence> <xs:element name="DetailId" type="xs:string" minOccurs="0"/> <xs:element name="DetailDescription" type="xs:string" minOccurs="0"/> </xs:sequence> </xs:complexType> The pertinent generated C# code looks like: [System.Xml.Serialization.XmlTypeAttribute(Namespace="xxxxx")] public class MyResponse { /// <remarks/> [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] public MyListDetail[] MyList; Note that the generated .cs code types MyList as simply an array of MyListDetail objects rather than typing it as a MyList object. This seems to cause a problem where the data put into the MyListDetail objects do not appear on the client side after calling the web service. If a "dummy" element is added to the MyList definition, the actual MyList data type is generated, and the data passed in the MyListDetail objects are passed back to the client as expected: <xs:complexType name="MyList"> <xs:sequence> <xs:element name="dummy" type="xs:string" minOccurs="0"/> <xs:element name="MyListDetail" type="MyListDetail" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> [System.Xml.Serialization.XmlTypeAttribute(Namespace="xxxxx")] public class MyResponse { ... /// <remarks/> [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] public MyList MyList; ...

    - Publish WMI instances from W32 service consumes memory without stop Hello to all, I'm developing a Win32 .Net service that publishes information into WMI by using Publish method, however once an instance is published, memory usage starts to grow without stop at a rate of 1Kb/sec. This problem only appears when publishing information through a service. Also I noticed that problem only appears on some machines (most of them) since a couple of my machines does not present the problem. Is there a way to solve this problem? I'll try to create a native provider and call it from the service but I prefer to use .Net and not to mix managed and not managed code.

    - Asynchronous event firing Hi: I was curious whether events fired as a multi-cast delegate were fired asynchronously or not. If the invoked delegate is OneWay, do I need to call GetInvocationList() (I think that's the name) and fire each one asynchronously to take advantage of the OneWay delegate, or will firing the event with one call do that for me?

    - Help: Placing Internet Shortcut for Windows Forms application (hosted on web server) on Desktop Hi there, I have a Windows forms app that resides on a web server. I (and my intended user base) access the application via an Internet shortcut, i.e. "http://servername/appshare/app.exe". That's all fine and dandy, as well as the setup and deployment project I had to write to install/uninstall a Site code group to give FullTrust to any applications from "servername", but that's another story (code's available if anyone's interested). So, one last thing I wish to do: During the install, create an Internet Shortcut on the desktop which points at "http://servername/appshare/app.exe". As far as I can see, there's no way to create an *internet* shortcut during the install process or via code - does anyone have any suggestions?

    - Managed extension is turned off automatically !! Hello Programmers, I have C++ unmanaged projects with managed extension turned on. They are compiling fine in developer computer. In the build computer, a single solution contains C#, .Net C++, C++ unmanaged and C++ unmanaged with managed extension turned on. But we are getting build errors for the "C++ unmanaged projects with managed extensions On". These errors are the same as what would be when the managed extension is turned off by accident in these projects. I have get local copy to TRUE, in the add references in all these projects. The managed project these unmanaged projects are trying to access is written in C++.Net. Any idea on how this could be?? .. Is this a bug .. any workaround ??

    - Dynamic menus - Collapsing and Expanding Hello All, I need to create a menu list on a page that will expand when clicked and stay expanded until clicked again. Actually, I want it to look just like the menus on the Microsoft Newsgroup homepage - with a plus sign to expand and a minus sign to collapse the menu. Also, I want to be able to add new sub-menu items in a single place (some kind of admin interface) and have them instantly be available when the parent menu is expanded.

I get it from the IPAddress.Address Object. Public Structure PingOptions Dim IPAdress As IPAddress Dim TimeOUT As Integer End Structure dim opt as PingOptions opt.IPAdress = IPAddress.Parse("192.168.1.128") ' Adresses bigger then A.B.C.127, have a negative adress value !!! ipaddr = System.UInt32.Parse(opt.IPAdress.Address) ' and couse exception here Dim ret As System.UInt32 'but i need an unsigned int here in the second parameter ret = IcmpSendEcho(h, opt.ipaddr, RequestData, CInt(RequestData.Length), IntPtr.Zero, reply._Data, reply._Data.Length, opt.TimeOUT) The Problem is that for IPAdresses, where the last Byte is bigger then 127. the generated Long Value for Adress is negative and the Parse Method to the uint32 couses an exception. Or should i declare the DestinationAdress as Long in the IcmpSendEcho and put in IPAdress.Address value directly. My assumption is that the Address value is created in the correct bitformat but becouse the CF is declaring it as a long it is interpreted negative. Or how else to get the correct Long Value from IPAdress.Address ?

Hi,

Everyday when I try to build my solution I get the message that I am missing
the assembly reference to the DSO dll.
Then I have to execute the MS SQL Server 2000 Analysis Services SP3 again to
retain the assembly reference for the DSO.
Then I can work all day installing and uninstalling my solution (with DSO
assembly), but the next day I get the same message again which tells me that
I am missing using statement or assembly reference for the DSO. Off course I
still have my using statement in the code so I conclude that my assembly
reference is messed up.
The properties of the DSO assembly reference are:
(Name) = Interop.DSO
Copy Local = True
Culture = 0
Description = Microsoft Decision Support Objects
Identity = {B492C3E0-0195-11D2-89BA-00C04FB9898D}\5.1\0\tlbimp
Path = D:\NET Projects\DREAMService\DREAMService\obj\Interop.DSO.dll
Strong Name = False
Type = ActiveX
Version = 5.1

Does anybody know what is wrong here (Maybe my Path to the dll is not
good!)?

Thanks in advance, Marco Liedekerken
