    - Consume webservices from ASP Hi, I'm wondering if there is a way of consuming webservices from any technology (.NET, JAVA based) from and ASP based application - not ASP.NET. If so please direct me on the steps to follow or to any URL you might know On the same issue, must I jave W2003 Server to use ASP.NET, I downloaded the .NET framework and installed it on my W2K and seem to work. But I'd like to know if I go into production with my website using this configuration if everything will work - it's more like a mix ASP/ASP.NET. The if this is possible maybe I could consume webservices using .NET ASP's and pass them to my ASP applications...any comments? regards, Rubén Valenzuela T.

    - Problem with WS method returning an array of complex type Hi, I developped a WS with IBM tools and used the wsdl in Visual Studio 2003 to add a Web Reference in my client. I have no problems with methods returning a simple type (ex. boolean) or complexType (ex. AccountInfo (a class defined by myself)). Though I got en empty object, when I am calling a method returning an array of complex type (AccountInfo). I checked the SOAP message and it contains all the informations. In the wsdl the array is defined by an unbouned element: <complexType name="AccountInfo"> <sequence> <element name="number" type="xsd:long"/> <element name="owner" nillable="true" type="xsd:string"/> <element name="label" nillable="true" type="xsd:string"/> <element name="rubrique" nillable="true" type="xsd:string"/> <element name="balance" type="xsd:long"/> <element name="currencyIso" nillable="true" type="xsd:string"/> <element name="availableAmount" type="xsd:long"/> </sequence> </complexType> <element name="getAccountsResponse"> <complexType> <sequence> <element maxOccurs="unbounded" name="getAccountsReturn" type="impl:AccountInfo"/> </sequence> </complexType> </element> Did someone return successfully an array (of simple or complex) type in a ws method call? :-) Anne C.

    - Access Hidden Colum Data in DataGrid I have a datagrid that I am attempting to edit a row within. I have no problem making the edit as long as my ID field for my DB is visible within the datagrid. I access it using the following: FLName = CType(CType(e.Item.Cells(1).Controls(0), TextBox).Text, String) However, if I make the field read only I receive an invalid paramater error. If I make it hidden I receive an invalid data type. Any suggestions on how to read this data for an update without making it visible to the user? Tag: geeting data frm excel using RTD Tag: 75651

    - Gracefully fail to start a service If my service fails to start, I'd like to notify the user and either display an error or direct them to check the event log to see more info. With Win32, you could return a non-0 number to the SCM during startup and a dialog would be displayed (by the SCM) showing the error number and directing the user to check the error log for further information. Is there similar functionality in .NET? I've tried throwing exceptions and calling Environment.Exit([some number]) in OnStart(), but both cause the SCM to display some useless dialog.

    - newline characters stripped from HTTPWebResponse Hi, I am downloading a .csv file and saving it locally. I am using HTTPWebRequest, getting the Response stream, and copying the stream to a file. It always works fine in the debugger, but most of the time the release version is stripping out many of the carriage returns/line feeds. My code: request = WebRequest.Create(myURL) response = request.GetResponse() Dim responseStream As Stream = response.GetResponseStream() Dim fileStream As New FileStream("myfile.csv", FileMode.Create) Dim r As New BinaryReader(responseStream) Dim w As New BinaryWriter(fileStream) Try Dim b(4095) As Byte Dim iBytesRead As Integer Dim iBytesTotal As Integer iBytesRead = r.Read(b, 0, b.Length) While iBytesRead iBytesTotal += iBytesRead w.Write(b, 0, iBytesRead) iBytesRead = r.Read(b, 0, b.Length) End While Finally w.Flush() fileStream.Close responseStream.Close End Try Any ideas why this might be happening? By the way, I am currently using WebClient.FileDownload, and it works fine, but I would still like to understand what I am doing wrong. Thanks, Brad Tag: geeting data frm excel using RTD Tag: 75610

    - Scrollbar Event Hi, I have a windows application that's using the Datagrid to display records. The datasource has the potential of being very large, so I'm only retrieving a certain number of records at a time into a dataset. So, as I scroll down to the bottom of my datagrid, the next page of, say 100 records is appended to the dataset and so on. The code I'm using in the Scroll event is displayed below. For Each c As Control In DataGrid1.Controls If c.GetType Is GetType(VScrollBar) Then Dim scr As VScrollBar = CType(c, VScrollBar) If scr.Maximum < scr.Value + 13 Then mnPage += 1 MapClientsToList() 'Populates the dataset with another page of records. End If End If Next The Problem I'm having is that when I scroll to the bottom, the event is fired, the dataset is populated as desired. However, the event is called again and again in a kind of loop until there is no more data. The scrollbar is apparently being positioned to the bottom every time the data is retrieved, calling my procedure each time. Does anyone have any thoughts on this?

    - How to load XML string into DataGrid and associate a element attribute to a column? Hi, I have a query return in a XML string. My XML result looks like: <activities> <activity> <subject>Win the Nobel</subject> <scheduledstart date="01/01/2005" time="00:00">2005-01-01T00:00:00-3:00</scheduledstart> </activity> </activities> If a dont have the scheduledstart element, the loading of result into a DataSet works fine, but when I try put the element and associate it with a column I get a error (something like "field scheduledstart not found"). See my code: NameTable nt = new NameTable(); XmlNamespaceManager nsmgr = new XmlNamespaceManager(nt); XmlParserContext context = new XmlParserContext(null, nsmgr, null, XmlSpace.None); XmlTextReader tr = new XmlTextReader(strResultsXml, XmlNodeType.Document, context); DataSet ds = new DataSet(); ds.ReadXml(tr); BoundColumn colAssunto = new BoundColumn(); colAssunto.HeaderText = "Assunto"; colAssunto.DataField = "subject"; BoundColumn colInicio = new BoundColumn(); colInicio.HeaderText = "Inicio"; colInicio.DataField = "scheduledstart"; dgResultado.AutoGenerateColumns = false; dgResultado.Columns.Add(colAssunto); dgResultado.Columns.Add(colInicio); dgResultado.DataSource = ds; if (ds.HasChanges()) dgResultado.DataBind(); How I associate the scheduledstart date and time attributes to two columns or the content of the element to one column?

    - GetValue and ISerialization, object not constructed?? I've got this strange problem in a class that uses ISerializable to serialize a NameValueCollection During deserialization, in the object constructor, after using GetValue to get the NameValueCollection from SerializationInfo, the NameValueCollection is not usable. It throws a NullReferenceException from pretty much any property/method. It is usable after the object is deserialized, but not in the constructor. I've narrowed down the code to a small sample. Can an object not be used during the deserialization constructor?

    - The Register directive for the referenced assembly Hello everybody! I am authoring my custom webcontrol and faced a very difficult problem. I have two assemblies: the first one contains some base classes and the second one contains a class which 1) Inherits a class from the first assembly 2) Contains references to the first assembly's class instances. When I drop the control from the second assembly onto a form, it adds references for both assemblies to the project, but it creates only one Register directive (which defines the TagPrefix) in the aspx code. At design time the control is displayed fine, but at run-time it throws an exception. To solve the problem one should manually add the Register directive for the base assembly. Does anybody know what should I do to that the Register directives for both assemblies were created automatically when one drops the control onto a form? Any help is appreciated Thank you in advance!

    - General access denied error adding user to group when impersonating Hi, I'm successfully impersonating an administrative user (using KB306158). I know it is successful because after the impersonation, the WindowsIdentity.GetCurrent().Name returns the admin credentials (before the impersonation it returns the logged-in user's credentials). I'm also testing the user's role (using IsInRole()) and receive True for Administrator. However, when attempting to add a user to the group, I receive a 'UnauthorizedAccessException: General access denied error'. Assuming that I copy-pasted the code from KB306158, so that I have the impersonateValidUser() function: this.Response.Write("<BR>before: " + WindowsIdentity.GetCurrent().Name); // returns the current non-priviliged user if( impersonateValidUser(admin, domain, password) ) { this.Response.Write("<BR>after: " + WindowsIdentity.GetCurrent().Name); // returns the actual admin account WindowsPrincipal principal = new WindowsPrincipal( WindowsIdentity.GetCurrent() ); this.Response.Write("<BR>in role: " + Convert.ToString( principal.IsInRole( WindowsBuiltInRole.Administrator ) ) ); // returns True // ...

    - Architecture: Scalability VS Performance This is a design / inheritance qus. I have class Task. This is a base class for some specific tasks Say WorkOrderTask : Task TimeSheetTask : Task Now Task has a function GetDetails() which gets all info about task. This makes a database call. I override this in the derived class. For implementing this in derived class i see following 2 approaches. Approach 1. WorkOrderTask .GetDetails() { Calls base.GetDetails(); to get base details, populates in the object Gets details specific to WorkOrderTask, populates in the object returns; } Approach 2. WorkOrderTask .GetDetails() { Get details specific to WorkOrderTask as well as the base class details, populates in the object returns; } The problem with Approach 1 I have to make 2 database calls. Approach 2 If theres some change in base class I need to take care of these in all the derived classes as well. Whereas, Approach 1 is advantageous here as by modifying only the Task.GetDetails funciton ( this is the base class ) function i have all the values and i do not need to touch the derived classes. Was thinking this might be a very common problem, so perhaps many of might be able to guide me on the approach i must take here. Perhaps anything other then the two i have talked about.

    - TCPListener and Windows service Hi All I have a scenario The server can dial into the client for several task 1. To fetch several rows from 2 or 3 tables - I plan to zip the files and send it across the network; to increase performance, instead of row-by-row update on the serve 2. To execute a remote application on the client and fetch data returned by the client application to the serve 3. To transfer some files to the client which would be either stored on the client's hard disk, or execute an application and pass the file to the remote applicatio 4. To update sql data on the client databas My initial design was to make four TCPlistener exes listening to 4 ports and appropriately make the listeners to the appropriate jobs depending on the port that receives data Is it possible for me to have just one windows service to be running on the client, and depending on the parameter sent from the server, do one of the four options stated above Please advise Thanks Tag: geeting data frm excel using RTD Tag: 75498

    - PerformanceCounter & PerformanceCounterCategory on Windows 2003 We are trying to create a custom performance counter and category in .Net 1.1 with Windows 2003 and XP as our operating systems. We use the following code to do this if (PerformanceCounterCategory.Exists(categoryName) PerformanceCounterCategory.Delete(categoryName) CounterCreationData ccd = new CounterCreationData(counterName, counterHelp, PerformanceCounterType.RateOfCountsPerSecond32) CounterCreationDataCollection ccdc = new CounterCreationDataCollection() ccdc.Add(ccd) PerformanceCounterCategory perfCategory = PerformanceCounterCategory.Create(categoryName, categoryHelp, ccdc) OurLibrary.Error.AssertThrow(perfCategory.CounterExists(counterName), String.Format("Expected \"{0}\" counter to exist.", counterName)) PerformanceCounter counter = new PerformanceCounter(categoryName, counterName, false) We get a "Category does not exist" InvalidOperationException when we assert that the counter exists. perfCategory != null at this time. The PerformanceCounterCategory.Create does NOT throw. We have tried many permutations of calls to try to get this to work, but it always throws. The odd thing is that the category and counter are actually created in the perfmon utility. We can see them from .net too, but not in the process that created them. We have tried this same code on Windows 2000 boxes and it works correctly. What is the problem with the Windows 2003 and XP operating systems that cause this to fail? We have searched the newsgroups and have not seen any explanations and very few instances of this problem. Are we the only ones using the .net performance counters Thanks Frank Tag: geeting data frm excel using RTD Tag: 75487
