    - strange behaviour of key() function Hi, I am using .NET 2.0 XslCompiledTransform As I understand if the second parameter of the xslt key() function is a node-set then key function returns union of results applying key functions to each node within the nodeset. So how could it happend that the following expression returns nothing (empty node set) < xsl:copy-of select = " key('Loops', $standardMapContext/xs equence/xs:element/@type) " /> And the following expression returns expected result < xsl:copy-of select = " key('Loops', $standardMapContext/xs equence/xs:element[@type = 'L_3']/@type) " /> The second expression goes right after the first one in my stylesheet. What I mean that the $standardMapContext/xs equence/xs:element/@type nodeset does contain an element with @type='L_3' but when I provide the entire nodeset to key() function it returns nothing. And when I manually filter out extra nodes it return as expected. What is wrong with my understanding of the key() function Thanks, Shurik.

    - XmlSerialization attributes: difference between [XmlElement(...)] and [XmlElementAttribute(...)] While familiarizing myself with XML Serialization and controlling serialization using attributes, I've become confused whether there is a different between the use of "XmlElement" or "XmlElementAttribute" in actually writing the attribute in a class declaration, and in general for any serialization attribute. For example, consider the following class: public class Test { public: // public, parameterless constructor req'd for serialization Test(void) {} public: [XmlElement("Member1")] int m_Member1; [XmlElementAttribute("Member2")] int m_Member2; } Even MSDN doesn't seem quite clear on which to use. From the code I've seen, it sounds like XmlElementAttribute is the object in the .NET framework that handles this, but I am to use "XmlElement" while actualing writing the attribute. In contrast, I have seen other code that appends the "Attribute" part of the object name. What is the difference, and which is correct Anjo Tag: .NET Framework Setup Enterprise Library for .NET Framework 3.0 .NET Development

    - Error generating classes using XSD.exe I will appreciate any quick help on this: I am trying to use xsd.exe to generate classes for a standard schema.

    - SqlDependency timeout problem I'm on XP, SqlSever 2005, .NETfx 3. I'm using SqlDependency to get notifications of changes to my data store. My intent is that when I set up a SqlDependency object, that it will be in effect "forever". However, I find that after 2 minutes or so, changes will not trigger notifications anymore. I initialize the dependency once per app domain thusly: SqlDependency .Start(_connectionString); this ._dependencyConnection = new SqlConnection (_connectionString + "Connection Timeout=" + Int32 .MaxValue.ToString()); _dependencyConnection.Open(); I set up a new notification (once at startup, and after each notification) like this: SqlCommand command = new SqlCommand ( "SELECT Revision FROM dbo.ConfigData where [Key] = '" + _ourKey + "'" , _dependencyConnection); SqlDependency dependency = new SqlDependency (command, null , Int32 .MaxValue); dependency.OnChange += new OnChangeEventHandler ( this .OnChange); SqlDataReader reader = command.ExecuteReader(); reader.Close(); This will fire notifcation for a change that happens within 2 minutes or so. After that, nothing. What am I missing here Thanks Riley Tag: .NET Framework Setup Enterprise Library for .NET Framework 3.0 .NET Development

    - System.Runtime.InteropServices.COMException (0x80010105) HELP!!! I have been charged with creating a mini web portal where customers can register a product and in return, get a activation license. I've successfully developed the app on my WinXP SP2 laptop using: Visual Studio 2005, SQL 2005, C#. I am inheriting an assembly that was written in 2003 which is responsible for actually creating the license. I call a function from this inherited .dll and receive the license without any error. Once the site was near completion, I migrated it to my Win2003 Server (standard ed, SP2). I registered my .dlls and added them as references to my newly-created solution. I then compiled the site and got the following error: Error: System.Runtime.InteropServices.COMException (0x80010105): The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT)) at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData) at LicenseKeyGen.LicenseKeyGeneratorClass.createLicenseBitString(String a_sFeatures, String a_sProductId, Int16 a_bEvaluationLicense, Int16 a_iEvalPeriod) at XDAL.LicenseDAL.GetFinalLicense(String ParamFeatures, String productID, Int16 ParamEvaluation, Int16 ParamEvalPeriod) in X:\Inetpub\wwwroot\xxx\LicenseDAL.cs:line 394 at XDAL.LicenseDAL.GenerateLicenceKey(String productID) in X:\Inetpub\wwwroot\xxx\LicenseDAL.cs:line 303 at XDAL.LicenseDAL.MatchAndUpdate_ProdID_IKey(String productID, String Ikey) in X:\Inetpub\wwwroot\xxx\LicenseDAL.cs:line 628 at XDAL.LicenseDAL.GetLicense(String productid, String ikey, String email) in X:\Inetpub\wwwroot\xxx\LicenseDAL.cs:line 526 at XBus.License.GetLicense(String productid, String ikey, String email) in X:\Inetpub\wwwroot\xxx\License.cs:line 61 at _Products_Licensing_editProduct.btnSubmit_Click(Object sender, EventArgs e) in X:\Inetpub\wwwroot\xxx\editProduct.aspx.cs:line 240 I then tried debugging to see if the correct parameters were being passed to the function. They are: if you can't see the image: 208.252.199.41/images/error-01.gif After reading some microsoft forum posts I came across: "I managed to solve this on our Windows 2003 machine.

I don't really understand it that well but this fixed it for us" I then did this too: if you can't see the image: 208.252.199.41/images/error-02.gif I am thoroughly baffled after 2 days of searching, Googling, calling colleagues, reading blogs, etc. There is so little documentation on System.Runtime.InteropServices.COMException (0x80010105) . Has anyone come across this error when transferring a site to a Win 2003 server Any advice/information would be GREATLY appreciated.

    - define a new querydef in an access db using asp.net My scenario is this: I have inherited a large access database, critical to a website. I need to do some work on the site which requires that I modify a number of tables and create a few ne querydef so support the work. The obvious soluition is to ftp the db locally, modify the file and upload it. But If possible I do not want to do this. I don't want to lose data and I don't want to take the db offline. So what I would like to do is create an aspx page which I can use to do operations like creae new querydefs. How can I connect to an access db to do these kind of operations As far as I can tell, the regular OleDbConn does not allow me to do these operations - rather I need to use the access object model. I suspect there must be some utility out there on the internet to do this kind of thing (a bit like phpmyadmin).

    - The located assembly's manifest definition does not match the assembly reference. Does anyone know how to have two versions of the same .dll file referenced in the same .net application Let me explain. I have an application that dynamically loads forms contained in other assymblies. The assymblies are in seperate folders with all of the .dlls necessary to run that form in the same folder. The problem I am having is that each of these forms use the same .dll file with different versions. I keep running into the following error when my application tries to open one of these forms: The located assembly's manifest definition does not match the assembly reference. I know that this means that one of my dynamically loaded forms is finding the wrong version of the assymbly needed for that form. I'm assuming this is because it's loading the assymbly for the other form. I am not sure why this is happening. I thought that if I kept the .dlls for the forms seperate in their own folders that it would use those first when loading the assymbly for that form. I have read other posts that would suggest that as long as my assymblies are not strongly typed (which they are not) that the assymbly resolution will look locally for the needed assymbly. My only guess is that since the .dlls that are needed for the form are in a folder seperate from the initially run application that it is by default looking in the GAC because it can't find it locally. This is my suspicion since if I copy the .dll that is giving me the problem to the folder running my main loader application then my form runs fine. If that is the case then I don't know how to make sure that each of my forms uses the correct version of their respective assymblies since I can't very well copy two versions of the same file into the same folder. I have searched and searched and tried everything I can think of with no luck. Any ideas If examples are needed I can see if I can post screen captures somehow.

    - "Deserializing" XmlNode.OuterXml to object, then back to XmlNode questions My application provides a GUI for users to edit xml documents. The resulting documents are used by other automated systems following a shared schema. I figured I could cut down on the amount of code I have to write if I used XSD.EXE to generate classes for me to databind the xml to my winforms controls. The nodes in the document are originally created in code using a default namespace declaration which is explicitly declared on the DocumentElement. To edit the nodes, I "deserialize" the OuterXml property of the target XmlNode into the appropriate class created by XSD.EXE, and the user can modify the properties with databound forms. When they click "Save", my code serializes the classes to xml in order to load them back into the source XmlDocument. That code looks like this: Code Block XmlSerializer serializer = new XmlSerializer (xsdObject .GetType()); StringWriter writer = new StringWriter (); serializer.Serialize(writer, xsdObject ); XmlDocument doc = new XmlDocument (); doc.LoadXml(writer.ToString()); // Retrieve the original XmlNode XmlNode oldNode = this .getDefinitionNode( this .metaData.Definition); oldNode.ParentNode.ReplaceChild(oldNode.OwnerDocument.ImportNode(doc.DocumentElement, true ), oldNode); It's ugly, but it works. My only problem is that the resulting xml comes with a bunch of extra xmlns attributes: xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance " xmlns:xsd=" http://www.w3.org/2001/XMLSchema " xmlns=" http://superlongschemaurl " I can delete the first two easily enough with no impact to schema validation, and I understand why I can't delete the last one (it's the namespace identifier that links to my schema). What I don't understand is why the resulting XmlNode that I import above explicitly writes the xmlns declaration to the file, even though the node doesn't have it before serialization, and since the default namespace declaration on the documentElement is in scope for all descendantelements. When I create the original node in the application, I pass in the correct namespace for schema validation, but it's never explicitly written to the nodes in the document--the declaration appears explicitly only once on the documentElement and nowhere else. Isn't there some way I can associate the namespace with these imported nodes without it explicitly redeclaring it in the output XML I know it doesn't hurt anything, but there are literally thousands of nodes in the source document, all of which will be edited by the user, and these unnecessary declarations actually have a significant impact on the size of the file (which can reach into the megabytes all by itself). Any space savings is significant to performance in a lot of ways, so any input would be really helpful. (Also, if anyone wants to suggest an easier way than using XSD classes to databind Xml to winforms controls, but that still benefits from schema constraints like XSD classes do, I'd definitely appreciate it.)

    - ILMerge: Problem with references Hi, I'm trying to use ILMerge to create components for the Umbraco web framework. I thought it would be nice is I only had to distribute one dll with my component. The setup I'm using is ( a bit simplified): MyComponent.csproj (Visual Studio web project) .... --References ----umbraco.dll (local reference, Copy Local == false) ----SomeComponent.dll (local reference, Copy Local == true) ----System.Web (GAC reference) .... The reason that I have Copy Local == false on the umbraco.dll is that this dll is part of the solution that my component must be deployed to. The SomeComponent.dll is a component used by my UserControls in my project and this is the dll I would like to merge with MyComponent.dll However if I execute: "ilmerge.exe /out:MyComponent.dll SomeComponent.dll" i get an error message saying: "Unresolved assembly reference not allowed: umbraco" I can however not just include the umbraco.dll since this would result in the classes within the umbraco.dll being defined twice when I deploy the MyComponent.dll in the umbraco web application. So my question is there anyway to avoid this error message or is ILMerge an all or nothing solution Regards, Rasmus Oudal Edberg Tag: .NET Framework Setup Enterprise Library for .NET Framework 3.0 .NET Development

I'm finding that I cannot create or check for the existance of Queues utilizing the HTTP channel whether they are private or public. Example code: string url = "FormatName IRECT=HTTP://myserver/ MSMQ/myqueue"; MessageQueue.Exists(url); MessageQueue.Create(url); Note: the annoying emoticon above shows up because its really a : D w/ no space For both of those methods I get errors eluding to - cannot create / check existance with that path syntax. I've also seen this example - changing the : to an = after FormatName, that seems worse off though just plain saying its an invalid syntax altogether. string url = "FormatName=DIRECT=HTTP://myserver/ MSMQ/myqueue"; As far as I've read, you can create / check the existance of Queues via HTTP, however I cannot get any example to work... all of the documentation I've seen only uses the OS direct path to do so.... Anyone have any ideas I can however retreive messages from the Qeueue via HTTP w/ that url syntax, but... w/ the architecture I'm working on I'd like to check for its existance first from the client.

    - .NET QueryBuilder and IN(Transact-SQL) function Hello! I am using Visual Studio 2005 and developing in VB.NET. I have created a standard windows application and am using the standard Data Access tools (MSDataSetGenerator) to create my datatables with tableadapters which represent my database in SQL Server 2005. If I want to select table data using a parameter that represents a single value, everything works fine using: Select * from Employees where EmployeeID = @EmployeeID [value of @EmployeeID = 1] However, if I want to select a subset of the records in the Employees table using: Select * from Employees where EmployeeID IN(@EmployeeIDs) [value of @EmployeeIDs = 1, 3] Some background, the EmployeeID is an Int field. I have tried declaring the @EmployeeIDs variable as String and it still doesn't work. I get an error that it cannot convert the string value of @EmployeeID to an Integer for the field EmployeeID. So, I guess my question is... does the .NET Queries TableAdapter not support Transact-SQL functions like "IN(" when passing in multiple values of EmployeeID Tag: .NET Framework Setup Enterprise Library for .NET Framework 3.0 .NET Development

    - Talking between two applications Hi. I am developing a client-server home automation application on which the RS232 serial port must be opened in order for a client application (such as a timer, lighting control, etc.) to talk to a Home Automation host application. It goes like this: RS232 (port) <-{> PowerLine Modem Communication (internal class) <-> Host (form application; internal class) <-> Insteon (public class) <}-> Client Applications The "{}" represents an entire assembly that is executable (calls out the Host form). The "s" in "Client Applications" can be visualized as multiple blocks connected to a single, big block; thus, if you visualize it in a diagram, you'll know what I mean, as multiple clients that talk (interface) with a central host (server) application. I can do that through .net Sockets (TCP/IP), but I have a class that use enums. Plus, the client and server applications will all be in one machine. With my explainations out of the way, plus I've coded everything like for setting up an RS232 communication for PowerLine Modem communication through Insteon network (refer to the link about Insteon), I have a couple of questions: How do I make my client application (timer/evenr or lighting control, for example) talk to the server application for gathering variables set by the server application How do I gather a state of a running application (example: if a client application requires a server application to run) For question 1, what I mean is if a server application's isConnected boolean variable is set to true (like when a server application instantiated a new PLM class, tells the PLM class to open the port, etc.) or not, whether an application received an acknologement from an Insteon PowerLine Modem (isPowerLineModemAvailable), etc. This is something that client applications must be able to communicate with the shared, single running instance of a server application.

    - Issue with SqlCommand and Parameters.Add My programs function is to query the dB, get all the table attributes, build the SQL query dynamically, then perform an update on the required fields. I am having an issue with the proper placement of the SqlCommand. Here are the steps my program is performing 1. Query the dB and get the attribures of the table (column name, datatype and length) 2. Build the following queries dynamically from the results and store it in a variables to be used later 1st query: UPDATE myTableName SET FirstName = @FirstName, SecondName = @SecondName 2nd query: SELECT FirstName, LastName FROM myTableName 3. I then do a common dataSet loop with the results from the 2nd query. 4. Inside the dataSet loop, the 1st query is now used and the WHERE statement needs to be appended, and this is where the problem begins. I am using Parameters.Add inside dataSet loop as well. Here is an example of the code: Code Snippet for (iItem = 0; iItem < dTable.Rows.Count; iItem++) { connection.Open(); SqlCommand commandUpdate = new SqlCommand (strSQL, connection); for (iItemRows = 0; iItemRows < NumberOfRows; iItemRows++) { strID = dRow[ "ID" ].ToString(); strFirstName = RowTableDetails[iItemRows, 0]; // these are the Parameter.Add strDataType = RowTableDetails[iItemRows, 1]; intLength = Convert .ToInt16(RowTableDetails[iItemRows, 2]); strDataValue = dRow[strColumnName].ToString(); if (strDataType.ToString() == "nvarchar" ) { commandUpdate.Parameters.Add( @"@" + strColumnName, SqlDbType .NVarChar, intLength).Value = dRow[strColumnName]; } strSQL = strSQL + " WHERE ID = " + strID.ToString() + "" ; } commandUpdate.ExecuteNonQuery(); commandUpdate.Dispose(); commandUpdate = null ; connection.Close(); } The issue is I need to have this WHERE statement appended to the strSQL: WHERE ID = " + strID.ToString() + "" But the SqlCommand commandUpdate has to be inserted before I am allowed to enter the commandUpdate.Parameters.Add parameters. Any ideas on the placement, or even a different approach Also, as I am creating allmost all the statements dynamically, does anyone know of any way to create the SqlDbType .NVarChar option dynamically I am using If statements for each SqlDbType, but it does not seem like the best option.

    - Compare MDB Files Hello! I need to compare the structure of mdb-files, to find missing tables, fields or indexes using VB.NET and... yes, that is the question. ADO.NET (and ADO too) do not support an object model to look into the structure of MDBs If they do, I cannot find it... So I looked into DAO Interop's Object Model, only to find it is not helpful, as it shows some properties (*) only as __ComObject (which cannot be casted to something else or iterated with For each) Any ideas What can I use in .NET to see how MDBs are set up Thanks, Ralf (*) DAO Interop does have tables and their fields, and also properties for fields - very nice! But when looking at indexes, the fields listing is only "object" and cannot be used or casted to something useful. Tag: .NET Framework Setup Enterprise Library for .NET Framework 3.0 .NET Development

Hi Mike, Enterprise Library 3.0 has released the third CTP in february 2007. The final release is not available yet (it should be by the end of march/april... you read more about it in the tom hollander's blog). The Core of Entlib V3 (App Blocks + config tool + VS Integration) runs over fx 2.0. You need to targte the fx 3.0 if you want to use the new Application Block Software Factory which is a Guidance Package to build your own blocks.

Here are some useful links:
