    - Exception: DataTable internal index is corrupted: '5'. on ... Yes It could be the problem. My DataSet is stored on the Application Cache and every user can potentialy access and, sometimes, modify the content of a row. But I had another exception telling that I cannot modify the same row at the same time. Now I modify it in order that the DataSet is now read only and I have no more exception on this DataSet.

    - http Response error Hi, for the past while ive been stuck with the following error when i debug my application "The server committed a protocol violation. Section=ResponseStatusLine" My application is sends 2 requests to a java servlet. The first request works fine. If I try to send any other request the error occurs. Ive looked around online about the error. I tried setting <httpWebRequest useUnsafeHeaderParsing="true" /> in the web config file but it does not work. Also I read that the iis server has problems if another application is using port 80. The servlet is configured to run on port 80 so I changed it to port 81. I still get the error. Im really baffled as to why this error is occuring. Any help or insight would be greatly appreciated. Thanks Dub /////Request 1 string url = "http://localhost:81/"; string result = string.Empty; string postData = "msisdn0=862324984"; Uri uri = new Uri(url); HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri + "demo1_res"); request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = postData.Length; // request.Referer = "http://localhost/demo1_res"; request.ProtocolVersion = HttpVersion.Version11; Stream writeStream = request.GetRequestStream(); UTF8Encoding encoding = new UTF8Encoding(); byte[] bytes = encoding.GetBytes(postData); writeStream.Write(bytes, 0, bytes.Length); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); Stream responseStream = response.GetResponseStream(); StreamReader readStream = new StreamReader(responseStream); result = readStream.ReadToEnd(); //////////////////////////////////// /////Request 1 string url2 = "http://localhost:81/"; string result2 = string.Empty; string postData2 = "info id=862324984&type=slir"; Uri uri2 = new Uri(url2); HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost:81/info id=862324984&type=slir"); request.Method = "Get"; request.ContentType = "application/x-www-form-urlencoded"; HttpWebResponse response = (HttpWebResponse)request.GetResponse(); Stream responseStream = response.GetResponseStream(); StreamReader readStream = new StreamReader(responseStream); string result = readStream.ReadToEnd(); Tag: ASMX Web Services and XML Serialization .NET and MSMQ .NET Development

    - error when running application Whenever i try to run windows media center, i recieve a message that says Fatal Execution Engine Error (0x7927e03e). It then says that Registered JIT debugger is not available. An attempt to launch a JIT debugger with the following command resulted in an error code of 0x2(2). Please check computer settings. cordbg.exe !a 0xa04 I think it has something to do with the .NET Framework. Whenever i try to remove .NET Framework 1.1 and reinstall it, it says that it can't find it on the computer, but it appears in the "Add/Remove Programs" list in Control Panel. Any help with this problem is greatly appreciated. Thanks. Tag: ASMX Web Services and XML Serialization .NET and MSMQ .NET Development

    - Concurrency violation while row exists Thank you for helping, i think we are on a lead here. What you say sounds very logic. I checked the UpdateRowSource state of the commands before changing it and it was set to Both. So that should be alright and changing it to FirstReturnedRecord did not change anything therefore. The error still appeared. Although the insert query doesn't return any information ofcoarse. So the dataadapter does not receive the id of the newly added row. If i understand your post and the help correctly. Now my new question is: how do i make sure that the dataset receives the newly added id. Should i run the insert first and receive after that the id in the same command or is there a better way And how do you explain the error appearing only now and then Thanks i think this is at least a step in the good direction. Chokamir PS the datagrid shows the correct id for the primary key, so is it possible that the dataset does not know it while the grid displays it Tag: ASMX Web Services and XML Serialization .NET and MSMQ .NET Development

    - XPath syntax for string with ' embeded Hello, I have coded an XPath "It's a Wonderful Life". If I search for "Wonderful Life" I find the correct node since I coded the contains function, but I'd like to be more specific and look for the exact title. The problem is coding the correct syntax that will make C# and XPath happy at the same time. Can someone tell me the proper syntax so that I can code the entire title In other words I'd like to code contains(title,'It's a Wonderful Life') but that generates a run time error of "invalid token". Omitting the contains function and coding this df:title='It's a Wonderful Life' produces the same result. Tag: ASMX Web Services and XML Serialization .NET and MSMQ .NET Development

    - Should webservice return custom entity or dataset (Consider performance) First, you should almost never return a string as XML. Read that sentence again. "string" as "XML". The two words are spelled differently, which is a hint that they are different. So, please don't act like they're the same. [This is more for other readers than for you] There won't be any boxing going on, so don't worry about it. Just use that array, or List<LineItem> to hold your line items. You can even return a List<LineItem>, and the client will see it as an array of LineItem. Tag: ASMX Web Services and XML Serialization .NET and MSMQ .NET Development

    - Generating proxy classes to individual files? I have 6 separate wsdl files which represent various HL7 v3 interactions. Each of these wsdl files declare the same base HL7 v3 data types. Each wsdl is about 350K in size. I have used Thinktecture's WSCF v0.6 tool to generate a separate class file for each data type (class). I have some minor problems using WSCF, so I was wanting to do the same thing using the standard .NET framework tools, i.e., wsdl.exe or wsewsdl3.exe. Unless I have missed something obvious, I cannot find a way of doing the same thing using wsdl.exe or wsewsdl3.exe. A couple of notes to assist in your answer: I am not the maintainer of the wsdl, so changing the source wsdl is out of the question There are 348 generated classes (1.5MB of C#) in all of the wsdl files, at least 1/2 of these classes are shared between all of the wsdl files. I need to add some additional constructors, methods and properties to other partial class declarations. I do not want to duplicate this code for each wsdl file. Currently, I have 25 classes that I need to enhance in this way. .NET Framework 2.0 Generating each wsdl file will overwrite any existing class file as they are all the same types. For example, HL7 v3 defines a data type II (two 'i's) which represents an identifier. Each wsdl file contains the exact same definition for the complex type II. For each wsdl file, it should generate a file II.cs which regardless of the wsdl, the generated file will be identical. Is there a way to use the standard .NET framework tools to generate individual class files for each type defined in them Thanks, Phil Bolduc Tag: ASMX Web Services and XML Serialization .NET and MSMQ .NET Development

I'm not sure if it's even possible considering I keep getting a read-only error when i try to modify a combo box's items at runtime...but i guess what i need out fo you guys is a simple procedure to get these items and store them into an array of variables...thanks so much!

    - QI Works, but object is null A little background... We have several COM Dlls, compiled in both 64 and 32 bit, each correctly works in a .net console app (32-bit to 32-bit console, etc). 2 of these objects are returned as out parameters from a 3rd. When we run 32-bit mode in IIS, evenrything works correctly, using the 32-bit version of the COM objects. We we run in 64-bit mode in IIS, some of the COM objects work and some don't. One in particular is getting an E_NOINTERFACE error why typecasting the object (returned) to the correct interop interface. If we break the code apart, the call returns a reference, and the typecast calls QI on the COM object. If we turn on ATL debugging on the com object, we see the QI for interface, and it works successfully. (see some sample code below) Anyone have a similar problem, or any ideas where we could look chad // This retrieves the COM pointer, where it is in another 64-bit process WestLib.OWest west = GetWest(); // This works SessionLib.Session session = (SessionLib.Session)west.Session; // This throws a COMException (E_NOINTERFACE) SettingsLib.Settings settings = (Settingslib.Settings)west.Settings; Tag: ASMX Web Services and XML Serialization .NET and MSMQ .NET Development

Hi, Some times ago I've asked a question about memory deallocation for the old method body after SetILFunctionBody http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1110346&SiteID=1 David answered me that memory was allocated by CLR and I haven't think about it. Also he said that "This memory can be mapped directly to the module containing the function and is therefore unfreeable". So my question is - Is there a way to understand whether the memory is unfreeable Can I save a link to that memory in order to use it in future PS. I do understand that this memory can be read only. What if I want to save the old method body and read it again after I've replaced it by SetILCodeMap Tag: ASMX Web Services and XML Serialization .NET and MSMQ .NET Development

    - why so slow? 1) When accessing SQL Server with any version of ADO you should use a provider-specific provider if one is available. In the case of ADO.NET this means using SqlClient. It's the fastest, safest and lightest. It also exposes all SQL Server functionality. 2) When running an application on a Windows system that has to share RAM and CPU time with other applications, you have to ensure that the application is given enough CPU time and RAM to do the job. How much RAM is on the laptop What applications are running when you run this test Is the SQLExpress instance on the laptop or being accessed via the net Tag: ASMX Web Services and XML Serialization .NET and MSMQ .NET Development

    - How to access router's webpage interface and restart it? LOL, using firefox��s DOM inspector, I��ve looked into this ��Apply�� button, it has a huge tree with parameters and attributes but one of them was: Onclick GURL('restart.htm') I thought this page restarts the router, but when I opened it with browser, it just shows the frame with countdown timer to 0 without restarting it. So I still can��t find what triggers it. Tag: ASMX Web Services and XML Serialization .NET and MSMQ .NET Development

    - Microsoft IIS FTP Server - Commands supported? Does anyone know which FTP commands are supported by the MS FTP server I've been working on my own server (to handle dynamic user/password) and have a requirement that it shall be equivalent to the MS FTP server. I'm having a hard time determining what that is (without exhaustively trying each command of course). /* From the RFC 959 document: 5.3.1. FTP COMMANDS The following are the FTP commands: USER <SP> <username> <CRLF> PASS <SP> <password> <CRLF> ACCT <SP> <account-information> <CRLF> CWD <SP> <pathname> <CRLF> CDUP <CRLF> SMNT <SP> <pathname> <CRLF> QUIT <CRLF> REIN <CRLF> PORT <SP> <host-port> <CRLF> PASV <CRLF> TYPE <SP> <type-code> <CRLF> STRU <SP> <structure-code> <CRLF> MODE <SP> <mode-code> <CRLF> RETR <SP> <pathname> <CRLF> STOR <SP> <pathname> <CRLF> STOU <CRLF> APPE <SP> <pathname> <CRLF> ALLO <SP> <decimal-integer> [<SP> R <SP> <decimal-integer>] <CRLF> REST <SP> <marker> <CRLF> RNFR <SP> <pathname> <CRLF> RNTO <SP> <pathname> <CRLF> ABOR <CRLF> DELE <SP> <pathname> <CRLF> RMD <SP> <pathname> <CRLF> MKD <SP> <pathname> <CRLF> PWD <CRLF> LIST [<SP> <pathname>] <CRLF> NLST [<SP> <pathname>] <CRLF> SITE <SP> <string> <CRLF> SYST <CRLF> STAT [<SP> <pathname>] <CRLF> HELP [<SP> <string>] <CRLF> NOOP <CRLF> Tag: ASMX Web Services and XML Serialization .NET and MSMQ .NET Development

Hi

I'm looking to use MSMQ to improve the performance of my Web Service. I would like the web service to drop something onto the queue, and then a windows service (sitting on another server) to come along and pick up that object - but only remove it once it's been processed and placed in the database - I don't however want another windows service to come and pick up the same item (because it's first in the queue) and process it aswell...does that make sense

If someone could point me in the direction of a great article about this I would be most grateful.

I'm also looking for things about clustering the webservice - so I assume the msmq would then be split across a number of servers - to me that sounds a bit dodgey - is it Would I need to have a server dedicated to msmq so that the 10 (for example) web services could place things on the queue, and then the 10 windows services can come along and pick the information up Is that possible

Thanks!! Paul

Hi Paul,

In order to make the things easier for you, you have two options here, WCF (http://msdn2.microsoft.com/en-us/library/ms789048.aspx) or a MSMQ custom transport for WSE (http://www.codeproject.com/useritems/soapmsmq_wse3.asp)

Both options meet your requeriments, altough the first one is more official. You can also use transactional queues, so if an error happens in the service, the message is returned to the queue.

Regards,

Pablo.
