    - Windows service startUp error Hi all, My question consists of 2 parts: 1) I have installed my windows service [by right-click on Setup.exe in SolutionExplorer, then Install ... ] onto a folder on my desktop. When I click on the MyNewService.exe file, I got the following error message: " Cannot start service from the command line or a debugger. A Windows Service must first be installed (using installutil.exe) and then started with the ServerExplorer, Windows Services Administrative tool or the NET START command. " 2) Is the problem because I need to install using "installutil /i C:\MyNewService3.exe" ? I tried that and i got the error message: " Exception occurred while initializing the installation: System.IO.FileNotFoundException: File or assembly name Documents, or one of its dependencies, was not found. " Any advice on understanding what this message says ? Thanks. regards, Andrew Tag: Fold and unfold easily code Tag: 137978

    - Caching of DateTime.Now? Hi... We have some elapsed time stopwatches using the QueryPerformanceCounter() win32 api, but since I was getting tired of doing the arithmatic all the time I added some DateTime.Now.ToString("HH:mm:ss.fff")'s to the log and I noticed an interesting quirk. There's often about a 5ms difference between the calculations of QueryPerformanceCounter() values and DateTime.Now and DateTime.Now is always the one behind. Is DateTime.Now cached for some period of time to avoid the expense of recalculation? Thanks Mark Tag: Fold and unfold easily code Tag: 137977

    - File Copy exception Hi all, I have created a windows service (my first service). I am normally an ASP.NET developer... The service is simple. All it does is to watch a directory and copy any files that land in it to another folder (in this case, the parent folder). This works fine most of the time, but my first sample file crashed it. It seems to be down to a file type problem. My sample file was a .bat file. I have now put a try/catch around the file copy and come up with _COMPlusExceptionCode -532459699 At the moment, it only seems to crash with .bat files. I have done a successful copy of app.config, *.txt. Any ideas? My code... public MyService() { InitializeComponent(); } protected override void OnStart(string[] args) { // TODO: Add code here to start your service. FSWatcher.Path = ConfigurationManager.AppSettings["WatchPath"]; } protected override void OnStop() { // TODO: Add code here to perform any tear-down necessary to stop your service. } private void FSWatcher_Created(object sender, System.IO.FileSystemEventArgs e) { try { System.IO.File.Copy(e.FullPath, "C:\\temp\\" + e.Name); } catch (Exception ex) { } } -- Best regards, Dave Colliver. http://www.AshfieldFOCUS.com ~~ http://www.FOCUSPortals.com - Local franchises available Tag: Fold and unfold easily code Tag: 137975

    - Metafile & Graphics I have a Metafile and a Graphics attached to it and I do several drawings on the Metafile through the Graphics. After the drawings I need to print the metafile. If I try to print the Metafile right away, nothing shows on the page, now, If I do a Graphics.Dispose() and then print the Metafile, it works without any problem. My problem is that after printing the Metafile I still need to work on it through the Graphics, but if I try to reinitializate the Graphics object with a call of Graphics.FromImage(metafile), I get a "out of memory" error. Is there a different way to create a Graphics from a Metafile ? Is it possible to have access to a Metafile which is attached to a Graphics, without having to dispose the Graphics ?

    - Compiling WF assemblies with /platform:x64 Hello, I have a service application that uses Windows Workflow Foundation as part of its processes. One of the class libraries in this application is a collection of custom WF activities that I have written to represent the bits of business process. The solution compiles fine when compiling with the /platform:anycpu flag and all is good, but when I try to compile the same solution with the /platform:x64 the class library with the WF activities fail with a "error 348: Compilation failed." It goes on to say "Unable to load one or more of the requested types." but that's all the help I get. I'm trying to build the application in a 32 bits machine running Windows XP SP2, but I will run it in a Windows Server 2003 64 bits. On the destination machine I have installed the 64 bit version of the Framework 3.5 and when looking in "C:\WINDOWS\Microsoft.NET\Framework64\v3.0" I can see only two sub-folders: "Windows Communication Foundation" and "WPF", whereas in the 32 bit version of the Framework 3.0 I can see a third folder called "Windows Workflow Foundation". Does it have any relevance? Any help is appreciated. Tag: Fold and unfold easily code Tag: 137972

I have added a Web Setup project to this solution, it Built Fine in VS2008. The installer works fine on windows Vista x64, but fails on the Virtual Machines of XP and 2003 R2.

    - Need help diagnosing WCF timeout exception Hello, I have a Windows Service-hosted WCF service that occasionally throws an timeout exception, or something that looks like one. The call chain looks like this: Client->WCF Service->COM Server->COM App The exception seems to appear as the call to the service is completing. Interestingly, these exceptions do not seem to affect the tasks the service is performing at the time of the error. If the errors are ignored all subsequent dependent actions are successful. The exception message is: The maximum retry count has been exceeded with no response from the remote endpoint. The reliable session was faulted. This is often an indication that the remote endpoint is no longer available. The inner exception says: The HTTP request to 'http://xpsp2client:8000/CubularityServies/CuIWfcService' has exceeded the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout. I also occasionally see an exception claiming that I've exceeded the inactivityTimeout of 00:10:00. OK. When I started seeing these I set all the timeout values I could find to 00:20:00 and the behavior was not affected. I'm setting the following timeouts in the .config file: For <binding> : receiveTimeout sendTimeout openTimeout closeTimeout For <reliableSession> : inactivityTimeout For <host> : openTimeout closeTimeout I'm wondering if there are timeout settings that I'm missing. I don't have any values less than 20min yet I get errors telling me I've exceeded timeouts of 1 and 10 minutes. I've used Intellisense to poke around and try to find properties that aren't obvious in the WCF Config Editor, but haven't turned up anything. Any suggestions? Keith P.S. I've turned on verbose logging for the service and am trying to understand them. Some exceptions are shown in the logs but not enough detail is given to pinpoint the source of these faliure.

When I opened a usercontrol in design mode, it used to have all datasets and tableadapters in toolbox, under a tab name with the name of the datasets project However, I had to upgrate to a new hdd, and did a clean Windows install, with VS2005, etc Now, when I open te solution and open a usercontrol in designer, I see only the other user controls, but no datasets or table adapters as I used to have before. Sometimes I see a tab with the name of the datasets project, but on it there is a text telling "There are no usable controls in this group" What happend? I mention, on old HDD I had instaled VS2003 and VS2005, on new one I have only VS2005 and installed VS2008 express, but then I removed it (as I thought maybe it caused the issue).

    - web deployed assembly I have a windows forms assembly that needs to be deployed via a webpage. This bit of code must provide a fully automated printing solution; in that it must accept a parameter containing a graphic image to print, and print it without any interaction. The issue I'm having is that it throws a security exception [Request for permission of type: System.drawing.printing.printingpermission ... failed]. This bit of code seems to work just fine if I use the print dialogbox and select the appropriate printer, and of course fails if I don't use the dialogbox. This seems to be a security issue, but I'm not sure where to look, or how to fix it.

    - Does HttpListener have the same quirk as HttpWebRequest Hi... We've implemented a server process using HttpListener to get and process certain requests, but we've been noticing some odd serialization that reminded me of a quirk in the client code. We recently discovered an odd behavior of HttpWebRequest in the client code where mixing sync and async methods resulted in everything quietly being sync. Specifically, we were using GetRequestStream() to send the data up synchronously then calling BeginGetResponse() to wait for the answer async. Well, it turned out that if you call a sync method first the async calls magically turn into synchronized ones - a rather undocumented behavior. Now we're seeing some similar quirks on the server side with HttpListener. We use BeginGetContext() to listen for a request. Our callback calls EndGetContext() to get the details and then immediately calls BeginGetContext() again to wait for another request. But then we read the request synchronously, post the work in a queue with the associated response object and move on. What we're seeing is that if the client sends several requests in a row, it blasts right through them but the server doesn't acknowledge even reading the 2nd request until after the response to the first request is written to and closed. Does HttpListener have some implicit serialization behavior like HttpWebRequest? Thanks Mark Tag: Fold and unfold easily code Tag: 137904

All of our assemblies were in the Framework64 temporary assembly cache for the running process but Process Explorer had flagged them all as being 32-bit code.

    - New Information on Error 1603 when installing .NET Framework all I was having major issues with installing Visual Studio 2008 on my computer. In particular the .NET 3.5 component required to run Visual Studio 2008. I tried everything that was online from editing registry settings, setting access permissions and all. I was able to install up to .NET FW 2.0 but past that I kept getting error 1603. This error is usually an access error telling the user that the target drive, folder or file is unaccessible. I found when doing a verbose log with the install the Microsoft IIS installation on my computer was corrupted and I needed to reinstall IIS on my computer. The best fix for this issue is 1st: Uninstall the IIS server off of the computer. 2nd: Run the .NET FW 3.5 Installer 3rd: Re-Install IIS from the Windows CD-ROM. 4th: I was then able to install Visual Studio 2008 on my computer after fixing this.

    - 1.1 install and 3.0 uninstall My computer runs Windows XP. I have a perpetual automatic update message for an Express Install. It is trying to install .NET Framework 1.1 Service Pack 1. It fails, says simply it was unable to install, and then goes back into the windows update queue. I have read on other posts to try and uninstall from 3.0 downward and then reinstall from 1.1 forward. I am also unable to uninstall 3.0. It says that a newer version is on my computer and I need to remove from Add/Remove programs. The problem is I was trying to uninstall FROM Add/Remove programs. I have also tried the 3.0 uninstaller on the Microsoft website but it says "We did not find specified products to be installed." Excuse me - didn't the download say "Uninstall?" HELP!!! I'm so confused! Tag: Fold and unfold easily code Tag: 137864

    - Socket connection was forcibly closed by the remote host Hy everyone, I have a little problem doing socket-programming. I've made a console-application with a socket listening on a sertain port to accept connections from other clients. The only thing my application has to do is accept the incomming clients, read the data and send it to a database. Everything works fine, but now and then my socket server seems to crash/hang. When I check my error-handling I see that my application is throwing this exception : "An existing connection was forcibly closed by the remote host" Restarting my application solves this problem. I don't know the reason, nor how to solve it. I've already surfed the internet al lot, but dit not come to an satisfying answer. Someone who can help me or who has experienced the same problem ?

    - Batch of Stored Procedures In our .Net 2.0 web service we need to insert/update data records into SQL Server 2005 that have been uploaded to us in XML documents. There could be anywhere from one to literally thousands of records in each uploaded transaction, and there are several dozen destination tables. Since performance is critical for this particular app, we were thinking of combining the stored procedure calls into configurable- sized batches using CommandType.Text and multiple concatenated EXEC statements, so we minimize database roundtrips as opposed to calling each SP individually in its own SqlCommand. Is this a good approach? One concern is that SQL Server would have to compile each and every batch since they will all be different, and the overhead involved in this could become significant. Is this really something to worry about, or not? Wouldn't a few batch compiles per transaction still be better than potentially thousands of roundtrips? Are there other problems with this approach? Of course we are planning to stress test to see how it actually responds, but I just wanted to get some opinions first in case someone has done this before and can give advice/recommendations/suggestions before we get too far into it.

    - shared assembly in the GAC? I have created a shared assembly(adoio.dll) I have set the parameter to local copy = false, but when I run my installer, I still get a copy of this dll in my directory. The intention was to have a single copy in the GAC so if I wanted to update it, it would be done in a single place. What am I missing? Thanks -- Arnie Tag: Fold and unfold easily code Tag: 137827

    - y of baseline in millimeter I need a method to write a string on a graphics pretty similar to DrawString but instead of specifying the (x,y) of the upper left corner of the imaginary rectangle that surrounds the string, I would like to specify the (x, y) of the baseline of the first caracter. Also, I use graph.PageUnit = GraphicsUnit.Millimeter, so, the (x,y) should be in millimeter. I tried to use some Font and FontFamily methods but couldn't figure out how to convert design unit metric into millimeter.

    - 'is not a valid virtual path' - host header help hello. i'm trying to setup a website on my local server when compiling it VS 2005 i get the error "is not a valid virtual path" from what i've read on the net, this is due to the fact that the site is using IP:Port, which is no longer supported in VS 2005. I have to use the IP:Port setup 192.168.2.102:8080 as my ISP blocks port 80 this is just a dev site, but i would like to access it externally, hence the port 8080. I've read that a few people got around this issue by using host headers. but i have yet to find an example of how. anything listed out on the internet refer to only using port 80. was hoping someone could help me with my setup of how to setup my site to user IP:8080 and point to port 80 as well via host headers so that the site can be built/compiled in VS 2005. I assume i then have to make a DNS entry, host file entry or WINS entry so that the site is accessible via the host header name. any help with that would be appreciated greatly as well my server is Win2003 w/ IIS6. and .net 2.0 thanks for any help Tag: Fold and unfold easily code Tag: 137822

    - Generic Dictionary Serialized with Xaml I'm having some troubles with Xaml as a serialization option. The problem lies in serializing nested Generic dictionaries: Basically, I see different XML if the first element of the dictionary's values is a primitive versus if it is another dictionary. If the first element is a primitive, I get an extra layer of XML tags (I say extra, but, they do seem to be neccessary). If the first element is not a primitive, those tags are missing and the XamlReader cannot read the output Xaml back in.. Here's a simple test case: namespace WpfApplication1 { public class MyDictionary : System.Collections.Generic.Dictionary<string, object> { } public class UseMyDictionary { public UseMyDictionary() { MyDictionary = new MyDictionary(); } private MyDictionary _myDictionary; [System.ComponentModel.DefaultValueAttribute(null)] public MyDictionary MyDictionary { get { return _myDictionary; } set { _myDictionary = value; } } public static void STRANGE_CASE() { UseMyDictionary use = new UseMyDictionary(); use.MyDictionary["b"] = true; Console.Out.WriteLine(System.Windows.Markup.XamlWriter.Save(use)); /* <UseMyDictionary xmlns="clr- namespace:WpfApplication1;assembly=WpfApplication1" xmlns:s="clr- namespace:System;assembly=mscorlib" xmlns:assembly="http:// schemas.microsoft.com/winfx/2006/xaml"> <UseMyDictionary.MyDictionary> <MyDictionary> <s:Boolean assembly:Key="b">True</s:Boolean> </MyDictionary> </UseMyDictionary.MyDictionary> </UseMyDictionary> */ use.MyDictionary["c"] = new MyDictionary(); Console.Out.WriteLine(System.Windows.Markup.XamlWriter.Save(use)); /* <UseMyDictionary xmlns="clr- namespace:WpfApplication1;assembly=WpfApplication1" xmlns:s="clr- namespace:System;assembly=mscorlib" xmlns:assembly="http:// schemas.microsoft.com/winfx/2006/xaml"> <UseMyDictionary.MyDictionary> <MyDictionary> <s:Boolean assembly:Key="b">True</s:Boolean> <MyDictionary assembly:Key="c" /> </MyDictionary> </UseMyDictionary.MyDictionary> </UseMyDictionary> */ use.MyDictionary["a"] = new MyDictionary(); Console.Out.WriteLine(System.Windows.Markup.XamlWriter.Save(use)); /* <UseMyDictionary xmlns="clr- namespace:WpfApplication1;assembly=WpfApplication1" xmlns:assembly="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:s="clr-namespace:System;assembly=mscorlib"> <UseMyDictionary.MyDictionary> <MyDictionary assembly:Key="a" /> <s:Boolean assembly:Key="b">True</s:Boolean> <MyDictionary assembly:Key="c" /> </UseMyDictionary.MyDictionary> </UseMyDictionary> */ } } } Tag: Fold and unfold easily code Tag: 137818

    - '<name>' is ambiguous in the namespace '<namespacename>' I have two ASP.Net web forms that utilize a common Web Service. In one of them, I'm able to instantiate an object via a call similar to: "Dim objService as TaskProcessor.TaskService"; it works like a charm. I try instantiating another object in the second web page using the same Web Service and statement, but it won't let me; instead, I get a message reading "'TaskService' is ambiguous in the namespace 'TaskProcessor'". Both of these web forms have the exact same Imports statements, so that isn't the problem. They also share the same business layer object library, so that isn't the problem.

    - Enterprise Library Cryptography Application Block - IHashProvider Hi. I'm using the Cryptography Application Block (in entlib 3.1) for the first time. In order to build a Hash Provider I must specify a 'Type that implements Microsoft.Practices.EnterpriseLibrary.Security.Cryptography.IHashProvider.' When I go to specify this value it prompts me to find an assembly on my computer that implements this. What exactly is this and how can I determine which assemblies can be used in this situation to implement a Hash Provider? If this is the incorrect forum for this type of question please direct me elsewhere. Thanks! Mike Tag: Fold and unfold easily code Tag: 137816

Hi,

I am looking for some addin-plugin-external tool for Visual Studio
2005 that would allow me to fold/unfold parts of the code in an easy
way. I don't like the default VS fold mode, its behavior is usually
unpredictable for me.

Thanks
