    - regex result is it OK to get regex result of pattern which has duplicate reference names like StrDatePattern As String ="\b(((?<year>\d{4})-(?<month>\d{1,2})-(?<day>\d{2}))|{(?<month>\d{1,2}) (?<day>\d{2}), (?<year>\d{4})))"? my code segment StrDatePattern As Sttring ="\b(((?<year>\d{4})-(?<month>\d{1,2})-(?<day>\d{2}))|{(?<month>\d{1,2}) (?<day>\d{2}), (?<year>\d{4})))"?

    - server side http for a non-web server I'm evaluating using http to carry data between a client and a non-web (C#) server application. This sounds great as the browser already has an http implementation and http is an open protocol. I was expecting to find a server piece that implemented the server side without requiring a full web server. I've looked around and found http.sys which sounded ideal but which doesn't seem have a C# API until Framework 2.0. Is anyone aware of either some kind of a C++ wrapper for http.sys or an alternate http implementation? If not, I can fairly readily build a wrapper on top of existing TCP functionality but I believe in reusing software when possible. I could also introduce IIS and create an ASP.NET "proxy" that could take http POSTS and relay them in the existing TCP format. Thanks Mike Tag: SQL Server Mobile on Tablet PC Tag: 102317

    - asynchronous logging with enterprise library logging application block. I am trying to use asynchronous logging using MSMQ and I have configured the properties as defined in the help (see below) I don't understand where the property 'MsmqPath' is in the app.config for MSMQDistrbutor.exe is it meant to be an aplication settings or an enterprise library setting in the app.config? I have tried creating an application setting value for it but it still fails to write to the logging destination? Also is this meant to be registered as a service? To choose asynchronous logging. 1.. In the Enterprise Library Configuration Console, expand Client Settings, right-click Distribution Strategies, point to New and then click MSMQ. 2.. Select the strategy and then specify the QueuePath for the strategy. 3.. Select Client Settings, and then modify the DistributionStrategy property to select the MSMQ distribution strategy you created. 4.. Open the MSMQDistributor.exe.config file with the Configuration Console, located in the directory containing the file MSMQDistributor.exe. Modify the MsmqPath property of the MSMQ Distributor Service to match the QueuePath property of the MSMQ distribution strategy you selected in step 2. This distribution strategy will be used for all messages that are not filtered out. Note Do not use the In Process distributor strategy and the MSMQ distributor strategy to log to the same flat file sink. Using both the In Process and MSMQ distributor strategies with the same flat file sink may result in simultaneous attempts to write to the same file. This will result in failure due to the file resource being in use by another process. Has anyone got any ideas? I followed the instructions below to allow for an MSMQ not registered with AD. http://mvwood.com/blogs/blog/archive/2005/03/04/321.aspx Cheers Ollie Riches Tag: SQL Server Mobile on Tablet PC Tag: 102316

    - Monitoring the existence of multiple files What's the best way to monitor an arbitrary set of files? In a program like a CD burning app, you've got a an explorer-like file system listview that you pick your files from and a listview for the CD compilation. If you populate the CD listview with 100 different files from 100 different folders, is there a good way to monitor any changes to the files in that listview (deletions, renames, moves, etc.)? This is mostly a GUI thing. I can easily check the existence of the files just prior to performing any operations on them, but I'd like to provide realtime feedback to the user so that they know when one of the files they've chosen is unavailable. I know there's the FileSystemWatcher class, but I suspect it's unwise to create 100 FSWs, each monitoring one file per directory. Tag: SQL Server Mobile on Tablet PC Tag: 102314

    - calling SQLLDR from C# (ASP.NET) Hi, I'm trying to call SQLLDR from ASP.NET (C#) to load data from a text file into a table. I'm not a windows/microsoft person so if you could give me a hint I'd appreciate it. I have tried a few ways to call sqlldr but it looks like the line with sqlldr command is just not being executed... There are no errors... I was told that it very well might be a permissions issue but I'm not sure where to look. I can execute my bat file from a command line with no problems and it works fine. Only from C# it doesn't work Here are my code samples: version 1: --------------- String strRunCommand = "SQLLDR "+p_DbConnection+" data='"+ p_LoadSourcePath+strTxtFileName+ "' control="+strFileType+".ctl log="+strLogFileName+" SKIP=1 ERRORS=10 BINDSIZE=1048576"; System.IO.File.Create(p_LoadDestinationPath+"load_run.bat").Close); StreamWriter sw = new StreamWriterp_LoadDestinationPath+"load_run.bat"); sw.WriteLine(strRunCommand); sw.Close(); System.Diagnostics.Process p = new Process(); p.StartInfo.RedirectStandardOutput=false; p.StartInfo.FileName = p_LoadDestinationPath+"load_run.bat"; p.StartInfo.UseShellExecute = false; p.StartInfo.WorkingDirectory = p_LoadDestinationPath; p.StartInfo.RedirectStandardError = true; p.Start(); p.WaitForExit();//wait with no time limit p.Dispose(); --------------- version 2: --------------- String strRunCommand = "SQLLDR "+p_DbConnection+" data='"+ p_LoadSourcePath+strTxtFileName+ "' control="+strFileType+".ctl log="+strLogFileName+" SKIP=1 ERRORS=10 BINDSIZE=1048576"; System.IO.File.Create(p_LoadDestinationPath+"load_run.bat").Close); StreamWriter sw = new StreamWriterp_LoadDestinationPath+"load_run.bat"); sw.WriteLine(strRunCommand); sw.Close(); System.Diagnostics.ProcessStartInfo psi = new System.Diagnostics.ProcessStartInfo("cmd.exe"); psi.UseShellExecute = false; psi.RedirectStandardOutput = true; psi.RedirectStandardInput = true; psi.RedirectStandardError = true; System.Diagnostics.Process proc = System.Diagnostics.Process.Start(psi); System.IO.StreamReader strm = System.IO.File.OpenText(p_LoadDestinationPath+"load_run.bat"); System.IO.StreamReader sOut = proc.StandardOutput; System.IO.StreamWriter sIn = proc.StandardInput; while(strm.Peek() != -1) { sIn.WriteLine(strm.ReadLine()); } sIn.WriteLine("EXIT"); proc.Close(); sIn.Close(); sOut.Close(); --------------- Tag: SQL Server Mobile on Tablet PC Tag: 102304

    - How to control order of properties in a class Hi, I have created a class with some properties Class Manager Private msName a s string Private msSurnaname as string Private mdSalary as double Public Property Name() as string .....Implementation ....Similarly implemented all the properties ...Some functions End Class To make class bindable I created a custom collection class Class Managers Inherits CollectionBase Public Function AddManager() as Manager 'implementation code.... End Function Public ReadOnly Property Item(byval index as integer) as Manager 'implementation code.... End Property End Class When I create instance of Managers class and added some manager objects to it. I tried to bind this to a third party grid (Data grid wont bind). It worked..But my problem is how I can control order of properties in columns. I see Columns in Surname, Name, Salary order...What should I do to ensure that my columns come in Name, Surname abd Salary order? I wonder How dataset achieve this? In dataset you'll always se fields in same order as they appear in XSD schema..Is there any way to achive this functionality?

    - Store date permanently Hi, I'm writing an activation system for a software, which allows a 15 days grace period. Now the question is... how can I store the date? It has to be kept even if the software is reinstalled, and it must not be too easy to find/delete. I could write a hidden file somewhere in the system or hide it in the registry, but if it is a limited XP account, I'm quite limited. Any genious idea!? I tried Isolated Storage, but just moving the assembly files creates a new Isolated Storage, so it's of no use. Thanks! Etienne Getting a beta version out soon...

    - .NET versions forward compatibility I posted this originally in microsoft.public.dotnet.framework.windowsforms -- but this is probably a better place... I am developing with VS 2003 -- .NET framework 1.1 I want my app to also run on .NET framework 1.0, so I define a .config file with the following: <configuration> <startup> <supportedRuntime version="v1.1.4322" /> <supportedRuntime version="v1.0.3705" /> </startup> </configuration> As a test, I am doing this on a plain-vanilla Windows app -- with a single form and a single textbox. But it does not work, on a .NET framework 1.0. Is there a way to debug a config file? Where should I look to make progress? Tag: SQL Server Mobile on Tablet PC Tag: 102265

    - Banker's Rounding by default, a big mistake !! Check the following example: it's a simple presentation of a ticket. double[] lines = new double[5]; //Set some VAT's lines[0] = 1.245; lines[1] = 1.246; lines[2] = 1.241; lines[3] = 1.275; lines[4] = 1.255; //Print and calc total double tot = 0; foreach (double val in lines) { tot += val; Console.WriteLine(" {0:0.00}", val); } Console.WriteLine("-----"); Console.WriteLine(" {0:0.00}", tot); Console.ReadLine(); This is the result : 1,25 1,25 1,24 1,28 1,26 -------- 6,26 Now take our your calculator (or excell if you like) an add the 5 lines manualy ! Your result wil be 6.28. -> 0.02 difference !!!!!!!!! If I give this ticket to a client he demands to now where the 0.02 euro has gone to. I know this has to do with the way C# round's its doubles (it is using the Banker's Rounding method) What i don't understand is why it's the default. To put it simple : How do I explain to someone (that is not a computer wiz), that 1 + 1 = 1.1 ???? Kind Regards Frank Vanderlinden Tag: SQL Server Mobile on Tablet PC Tag: 102256

    - Q re class layout with embedded structs A friend and fellow programmer asked, and I didn't know the answer: When a CLR class contains fields of non-scalar types (structs, say), are these structs then laid out in memory immediately within the class instance image, or are they converted implicitly into reference types and only references to instances of these stored in the class instance? According to him, the reflection APIs leave the impression that the latter takes place, whereas the SOS documentation suggests the former. To clarify, I'm referring to fields of types that are not usually reference types (structs) as opposed to arrays and strings that are of course always stored by reference.

    - Bulk Import - Thread was being Abort I am facing a unique problem where i am reading an XMl stream(8000 records) using open XML into SQL server > The problem is that whenever i execute the stored procedure it starts inserting data but suddenly stops at about 1 min 45-50 secs time. The import stops and the error is "Thread was being aborted". The whole stuff works fine when i connect to the database server from local machine. The database server is located at a remore place and the live application resides in the same place as of the database server. I get this problem when i try doing import logging in to the live server. i dont get this problem when i try doing this locally to the remote database server Settings : IIS6.0 and ASP.NET, SQL Server please suggest if there are any web server based settings which are forcing the import to time out.

    - strong name using al.exe and csc.exe I'm very much a beginner with C# and the .NET Framework environment, and am writing and building C# programs using the command line CSC.EXE compiler. What I'm trying to do now is try out some of the evidence options and the security policy settings. Code Signing and using this via certificates and Publish evidence is working fine, but I'm a bit stumped by strong naming at the moment. I've created a key pair using sn.exe, and read that I sign with this to an assembly before it's built (so not to a completed .exe). This seems to be the way to go from what I've read: AL.EXE /out:testapp.exe testapp.netmodule /keyfile:keypair.snk So far I've been using /target:winexe in CSC.EXE, so don't have the module files AL.EXE wants. I tried changing the CSC.EXE command line to: CSC.EXE /target.module /reference:... testapp.cs This allowed AL.EXE to complete without error messages, but the resulting .EXE says it's not a valid Win32 executable. Can anyone point me in the right direction to getting a valid Win32 executable that is strong named, using only the command line tools of the SDK? Danny.

I have a ASP.NET(C#) based web service program which acts as the server program and a client program, both the programs residing at different locations. I am passing parameters using WSE methods, from client program to server program and viceversa. Say for ex, the server program has the system time of 10:00 AM and the client program has the system time of -5 hours to the server program. now, when i want to login to my client program, i have to pass on my username and password to the server program. In doing so, since there is a time difference of -5 hours, and i get back an error saying "Creation time can not be in the future". I put up the following code at the server program to resolve this issue..but it is giving syntax errors. <configuration> <microsoft.web.services2> <security> <defaultTtlInSeconds>86400</defaultTtlInSeconds> <timeToleranceInSeconds>86400</timeToleranceInSeconds> </security> </microsoft.web.services2> </configuration> Please let me know if there are any other methods to resolve this problem or any other configuration settings to be done!

    - regasm issue, VB.net com dll I have created a DLL using VB.net for com interopt for use within my VB6 application. It works fine on my machine - I run the regasm, it registered and drag the dll in to the assembley folder. However, when I distribute the DLL to a end-user machine witht the .NET 1.1 framework I have some issues. Obviously, the COM isnt registered so I get a ActiveX can't crate obkjct error in my VB6 app. So, I go and try to run regasm to register it.. but when I run regasm, it's not a reconized interneal or external command in windows XP. RegAsm is in the .NET framework folder, so I assume the windows PATH enviroment variable is not pointing to this path. So, how do I distributee and regasm a dll file? How do I determine the path the regasm? Thanks Jason Roozee Tag: SQL Server Mobile on Tablet PC Tag: 102167

    - Otpimization of vb.net application using NTD Hi All, We had developed a .Net application which has the following environment Uses the No touch deployment concept Uses framework 1.1 on client and server machine, Visual studio 2003, Sql server 2000, Deployed on a windows 2003 box. Reporting is done using Crystal reports 10 A third party component grid from DevExpress has been used on all the forms in the application. And the No touch deployment exe uses webservice hosted on the web server which call the .net dlls for communicating with the database which is hosted on its own machine. We use SOAP for validation. All of my tables have indexes on them. Application uses customized SOAP headers to communicate with the webservice. The application is deployed over the internet in CT and the client is using it in Houston over the internet using a T1 connection. Most of the times it is ok, but at time the performance of the application, which depends a lot on the speed of the internet connection is very slow. Very soon we are going international on this application which mean that there would be clients in Europe, Asia who would be using our application hosted in CT. My question is considering this environment the application is developed and deployed in, can any one suggest ways of optimizing this .net application, either database wise or .net optimization or configuration. I know there is already a latest framework out there, 2.0(if I am no wrong), can any one give me reviews on it and also tell me if in any way it optimize the application to run any faster. Thanks Muzammil Tag: SQL Server Mobile on Tablet PC Tag: 102166

    - System.Treading.Timer stops firing events Hi everybody. Recently I ran into situation with System.Threading.Timer in my ASP.NET application. I reinstalled Windows on one of my servers and got timers stop firing events after while, they just stop functioning one-by-one. Here is detailed explanation. I run application on 2 dedicated Win 2003 servers. Server A serves about 1000 active simultaneous users (150-200 aspx page requests per second), Sever B serves about 400 users (80-100 aspx requests per sec). Application is the same. Machine.config is identical. maxWorkerThreads and maxIOThreads bumped to 40. minFreeThreads = 8. There are about 25 static timers throuout the application and there are some dynamicly created timers. Recently I realized that hosting company did not install SP1 for some reason, but applied critical hotfixes. I asked to reinstall OS on the servers, so far they did it on server B. Now, after installing Win 2003 on server B, with SP1 and all recent updates, and installing my application there, I'm getting my timers stop working. Possible exceptions in timer events are silenced. Logging shows that timers work normally for a few minutes and then next event just never happens. If I force timer by calling it's Change method, it works for a few minutes and then dies again. Below is simplyfied code sample and a result log. Again, it works fine on Win 2003 without servicepack, and does not on Win 2003 SP1. The timers are not accessed from any other place, they are being created on app init and then managed in Change method in timed event (see code). Eventlog does not show any threads being terminated. Also, I noticed that even though .Net version is the same on servers A and B (1.1.4322.573), the behavior is a bit different. In particular, on server A bad viewstate causes exception with message "The viewstate is invalid for this page and might be corrupted." while on server B exception message includes as well client IP, requested URL, and viewstate. Does anybody have any idea what all this about? Any hint? For now I had to shut down server B and let server A handle all the work. I've had similar problem with System.Timers.Timer before. Since I switched to System.Threading.Timer, it was gone. And now... ups... Code sample. Global.asax.cs namespace VR { public class Global : System.Web.HttpApplication { private Common.AppTimers appTimers; protected void Application_Start(Object sender, EventArgs e) { appTimers = new Common.AppTimers(); } } } vrTimers.cs using System; using System.Threading; namespace VR.Common { public class AppTimers { private Timer tmTimedWork; static private AppTimers appTimers; public AppTimers() { try { VR.Logger.Log(VR.enumLogs.Logic, "Init timers"); tmTimedWork = new Timer(new TimerCallback(OnTimedWork), null, 7000, 10000); appTimers = this; } catch(Exception ee) { VR.Logger.Log(VR.enumLogs.Logic, "AppTimers(): " + ee.Message); throw; } } public void OnTimedWork(object source) { VR.Logger.Log(VR.enumLogs.Trace, "OnTimedWork begin"); try { tmTimedWork.Change(120000, 600000); lock(tmTimedWork) { long period = SomeClass.SomeStatic() * 1000; tmTimedWork.Change(period, period); VR.Logger.Log(VR.enumLogs.Trace, "OnTimedWork end "+period.ToString()); } } catch (Exception ee) { tmTimedWork.Change(5000, 5000); VR.Logger.Log(VR.enumLogs.Logic, "OnTimedWork: "+ee.Message); } } } } The log looks like this: 8/31/2005 4:37:46 AM: OnTimedWork begin 8/31/2005 4:37:46 AM: OnTimedWork end 1000 8/31/2005 4:37:47 AM: OnTimedWork begin 8/31/2005 4:37:47 AM: OnTimedWork end 1000 8/31/2005 4:37:48 AM: OnTimedWork begin 8/31/2005 4:37:48 AM: OnTimedWork end 1000 8/31/2005 4:37:49 AM: OnTimedWork begin 8/31/2005 4:37:49 AM: OnTimedWork end 1000 8/31/2005 4:37:50 AM: OnTimedWork begin 8/31/2005 4:37:50 AM: OnTimedWork end 1000 8/31/2005 4:37:51 AM: OnTimedWork begin 8/31/2005 4:37:51 AM: OnTimedWork end 1000 8/31/2005 4:37:52 AM: OnTimedWork begin 8/31/2005 4:37:52 AM: OnTimedWork end 1000 8/31/2005 4:37:53 AM: OnTimedWork begin 8/31/2005 4:37:53 AM: OnTimedWork end 1000 8/31/2005 4:37:54 AM: OnTimedWork begin 8/31/2005 4:37:54 AM: OnTimedWork end 1000 Dmitry.

    - Logging & Instrumentation App Block & ASP I'm using the June release of the logging & instrumentation block. I have two categories set up, each logs to a different sink (one goes to the application log, the other to a text file.) When I run my test code as a regular windows app, everything works fine. When it runs from within a web service, I only see the message to the event log - the text file never gets created. I don't see any errors, and the second message does not show up in the application log as it would if there were an error. What am I missing here?

    - Executing Assemblies on Shared Paths Hi, We are a software development team for a retail company, all of the programs we develop are for use internally on our network. Recently, we have moved towards thin-client technology with everyone running remote desktops using Citrix. This proves to be troublesome when deploying - only domain administrators can actually install anything onto the Citrix Server itself. Since we have a farm of about 30 servers, we have to schedule in a deployment date & ensure the Citrix team carry out the install correctly and replicate it across all servers! We've got around this in the past by deploying onto a network share that has user specific data in. Eg; \\SharePath\data\UserName\Program Files\MyExecutable.exe This ensures we are in control of our programs, we have an auto-update program that rolls out any fixes or amendments we have made to programs - there is no major delay in rolling out a new version. In the .Net framework, there are security issues when running from a shared network drive. What is the best approach to allow us to continue to run an executable from a share path, using resources located locally on the Citrix Server? We have a Strong Name key file for our department that we sign all of our programs with. If the Citrix team amend the security configuration for the .Net framework on each of the servers, can we trust all assemblies signed with our Strong Name Key so that they can run from network shares (as in .7 of .NET Framework Enterprise Security Policy Administration and Deployment FAQ?) Is this the best approach to allow us to continue share deployment? Thanks Tag: SQL Server Mobile on Tablet PC Tag: 102130

    - Running Two Visual Studios at the same time, Dll's are being locked I am having a problem when running two Visual Studios at the same time. I know it is not a good idea to run Two Visual Studios at the same time but in this case I have to (Unless you have another way of debugging a webservice and a Client at the same time) I am trying to debug a Webservice in the one Visual Studio and in the other Visual studio I am debugging the client application. This all works fine for a while until one or more of the dll's that the WebService references gets locked. This dll is also referenced from one or more of the projects on the client app. Both of the Visual Studio program's compile there solutions just fine. Its when I try to run the webservice that I get a configuration errror and it tells me that access is denied to one of the dll's. This is not always the same dll as it randomly locks these files.. The only way I can recover from one of the dll's being locked is to restart my computer. This is slowing dev time down. I am looking for a way to unlock these dll files so that I dont have to restart my computer to get past this.

I'm trying to load data on a SQL Server CE database. Doing it on the Pocket
PC takes very long. I though I'd load it on the desktop using the tablet PC
API, using Visual Studio 2005 Beta 2 and Sql Server 2005 (Mobile).

I'm following instructions provided in the help file for Sql Server 2005 -
"Building a SQL Server Mobile Application for Tablet PCs". I'm having 2
problems.

1. I can't find "Microsoft Tablet PC API" under .NET assemblies, to add a
reference.
2. I did the rest - added "System.Data.SqlServerCe.dll" as a reference.

The application builds fine, but when it runs, it immediately stops with
this error:

System.IO.FileLoadException was unhandled
Message="Could not load file or assembly 'System.Data.SqlServerCe,
Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one

match the assembly reference. (Exception from HRESULT: 0x80131040)"

Hi

Since VS.NET 2005(Whidbey) has not been released, it is still in the beta
test period, so the behavior may be different from the final release.
So far Whidbey issue is not officially supported.
For Whidbey issue, you may try to post in vs2005 forum.
