    - Console application will only run on machine where application was compiled I have written a simple console application that will only run on my machine. I can run the application outside of the IDE, but on other units I get a message that the system cannot execute the command. I installed VS 2005 on another computer to see if there was some kind of dependency problem but this did not help. I created a new project and compiled it with all of the default options, no luck. The program compiles fine and executes without any errors on my computer. This tells me that I have some type of a dependency issue, the question is where do I look to find the problem? Thanks for any input. Tag: Windows Workflow Visual Designer Tag: 128391

    - RegEx and Vb.net /// "Unrecognized escape sequence" I have a fairly simple RegEx code below. I am given a file name, (which I don't control) , and need to change a folder name in it. The code below is choking on the filename not being escaped. "Unrecognized escape sequence" While I can escape the findValue and replaceValue, I don't necessarily control the fileName value. Aka, all I can do is manually string.Replace the fileName value. (Unless someone knows better than I) Do I have to do a string.Replace here? ( to make all the \ into \\ ) Or am I missing some trick in vb.net. ----------Start VB.Net code Dim fileName As String fileName = "C:\wutemp\myfile.txt" '<< this is given to me, I cannot simply say " filename = "C:\\wutemp\\myfile.txt" " Dim replaceRegEx As System.Text.RegularExpressions.Regex = New System.Text.RegularExpressions.Regex(fileName, getRegexOptions()) Dim findValue As String = "\wutemp\" Dim replaceValue As String = "\newfolder\" Dim newFileName As String = replaceRegEx.Replace(fileName, findValue, replaceValue) Private Function GetRegexOptions() As RegexOptions Dim options As RegexOptions = New RegexOptions options = options Or RegexOptions.IgnoreCase Return options End Function PS This is a repost. But I marked the other post (in .language.vb) as "IGNORE do not reply here". .. Tag: Windows Workflow Visual Designer Tag: 128388

    - The generic type 'System.Collections.ObjectModel.Collection`1' was used with the wrong number of generic arguments in assembly 'mscorlib' Has there been any resolution to this? I am seeing the same problem. The code seems to run ok but while I am stepping through it while debugging VS shows the value of count in my watch window as this error: {"The generic type 'System.Collections.ObjectModel.Collection`1' was used with the wrong number of generic arguments in assembly 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.":"System.Collections.ObjectModel.Collection`1"} Integer Like I said the code seems to be running ok but I am concerned that there is an underlying problem. Basically I have an abstract base class that derives from System.Collections.ObjectModel.Collection(Of T). I then have classes that derive from my base class. Any thoughts?

    - Enterprise Library 2.0 configuration error It is my intent to utilize the Enterprise Library Application Blocks. I am new to dotNet. I have downloaded the 'Enterprise Library - January 2006' version. The solution built successfully and I can execute the 'Hands on Labs' for logging. To transition to my code base, I did the following: created a C# console application, added the project references (Microsoft.Practices.EnterpriseLibrary.Common.dll Microsoft.Practices.EnterpriseLibrary.Logging.dll Microsoft.Practices.ObjectBuilder.dll), created the app.config file with the 'Enterprise Libray Configuration' utility (contents below), saved and closed both solution and configuration files. When I execute the solution within Visual Studio 2005, I receive the following error: The configuration section for Logging cannot be found in the configuration source. A section with the name of "loggingConfiguration" definitely exists. It is like it does not see my app.config file. - app.config contents - <configuration> <configSections> <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null" /> </configSections> <loggingConfiguration name="Logging Application Block" tracingEnabled="true" defaultCategory="General" logWarningsWhenNoCategoriesMatch="true"> <listeners> <add source="Enterprise Library Logging" formatter="Text Formatter" log="Btest" machineName="" listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.FormattedEventLogTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null" traceOutputOptions="None" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.FormattedEventLogTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null" name="Formatted EventLog TraceListener" /> </listeners> <formatters> <add template="Timestamp: {timestamp}

    - "Certificate chaining error" attempting to sign ClickOnce manifests with mage.exe Up until now, we've been signing our manifests using the temporary certificate built by Visual Studio. We now have a certificate from Thawte. Since Thawte only provided an ".spc" and ".pvk" file, and mage.exe requires a ".pfx" file, I had to use the pvk2pfx tool to create the pfx file. When I run mage to sign, like this: mage -s myapp.exe.manifiest -cf ourcompany.pfx -pwd xxx We get the subject error message. I consulted with Thawte, and they provided another microsoft tool (pvkimprt.exe) to generate the pfx file. That didn't work either - same error. Can anyone shine any light on this? I don't even know what the error message means... Tag: Windows Workflow Visual Designer Tag: 128375

    - ASP.NET multiple pages with very similiar layout and logic I have a complex page (with 8 complex user controls, and many other asp.net controls.) I have 2 very similiar pages to create, each page differing only from the others in one control. What is the best way to achieve this? I would guess that I have 3 alternatives. 1.) Visual and Logic inheritance. I know absolutely nothing about this in ASP.NET, and I haven't found anything that appears immediately simple ( i am in a rush to get this job done!). 2.) Have one page with all the controls on, and pass a parameter in the request for the page informing it which identity it should assume - i..e. if "PageA" is sent in the page request, the page should behave like and contain the controls of a "PageA" type page, etc... This would appear simple, though the different pages are to have different security permissions - I intended for each page to be in its own folder with the web.config file for that folder definining the access rights for the logged in user. Having one page to do the work of 3 would mean that I would have to do the configration work in the top level web.config file, which seems a bit more onerous. 3.) Put the contents of the page I have in now into a user control, and put this user control into 3 different pages. My main worry about this is the degree of processing overhead involved at the server, since the control would be complex (many controls + 8 user controls within it). However, it would mean that I could have 3 distinct pages that I could more easily apply user access rights to. I'm from a winforms background, so a lot of the concepts are quite new to me - I'd appreciate any feedback on this. Regards, Greg. Tag: Windows Workflow Visual Designer Tag: 128368

    - Reflection and Inheritance question. I'm new to reflection and would like to know if what I want to do is possible. So far I haven't seem much value to reflection (for my needs) but that could be the result of not using it properly, or perhaps my architecture is inherently flawed. I have the following: class baseClass { protected object _sharedProperty; public new baseClass(){} public object Shared { get {return _sharedProperty;} set {_ sharedProperty = value;} } public void SharedMethod() { // do something } } class classA : baseClass { private object _property1; public new classA(){} public object Property1 { get {return _ property1;} set {_ property1 = value;} } } class classB : baseClass { private object _property2; public new classB(){} public object Property2 { get {return _ property2;} set {_ property2= value;} } } public static void Test(string className,object propertyValue) { Type runtimeClass = Type.GetType(className); if(((int)myEnum.value1 & runtimeClass.Shared) != 0) { System.Reflection.PropertyInfo myProperty = runtimeClass.GetProperty("Property1"); myProperty.SetValue(runtimeClass,propertyValue,null); <- fails here } if(((int)myEnum.value2 & runtimeClass.Shared) != 0) { System.Reflection.PropertyInfo myProperty= runtimeClass.GetProperty("Property2"); myProperty.SetValue(runtimeClass,propertyValue,null); <- fails here } } So, basically both ClassA and ClassB inherit from baseClass. They obviously share properties/methods but also have their own. Based on certain conditions I want to set a property value of a class (if it exists - I'm not testing for it in the code provided but plan on it) without knowing which class until run-time. The class that I want to instantiate will be only known to the procedure as a string value. I'd like to be able to dynamically declare a variable as type "className" at run-time based on what the string value is passed in (for the sake of example say that the string being passed in IS the fully qualified name of the class. I then want to be able to access and enter property values for the particular class. But the problem I'm having is that when I try to set my property value the first argument of the SetValue expects an instance of an object with the type equal to that which I'm trying to set (which I think is kinda dumb given that if I knew it I would probably just instantiate it and set the properly directly). Anyway, clearly I don't know what this object is supposed to be so I don't know how to get past this exception. Does anyone have any thoughts? What I'd love to do is something along these lines (pseudo-code): public static void Test(string className,object propertyValue) { baseClass runtimeClass = new baseClass(); if(((int)myEnum.value1 & runtimeClass.Shared) != 0) { ((className)runtimeClass).Property1 = propertyValue; } if(((int) myEnum.value2 & runtimeClass.Shared) != 0) { ((className)runtimeClass).Property2 = propertyValue; } runtimeClass.SharedMethod(); } What I don't want is the following because this can and will get quite enormous given the number of properties and flag values I have: public static void Test(string className,object propertyValue) { baseClass runtimeClass = new baseClass(); if(((int)myEnum.value1 & runtimeClass.Shared) != 0) { if (className == "ClassA") { ((ClassA)runtimeClass).Property1 = propertyValue; } if (className == "ClassC") <-- assume this class also inherits from baseClass { ((ClassC)runtimeClass).Property1 = propertyValue; } } if(((int) myEnum.value2 & runtimeClass.Shared) != 0) { if (className == "ClassB") { ((ClassB)runtimeClass).Property2 = propertyValue; } if (className == "ClassC") <-- assume this class also inherits from baseClass { ((ClassC)runtimeClass).Property2 = propertyValue; } } runtimeClass.SharedMethod(); } Thanks, Frank Tag: Windows Workflow Visual Designer Tag: 128367

    - UdpClient Stop Receiving Broadcast Datagram On Lan When Connect to Internet My code is below and the platform is Win2K3 R2: using System; using System.Net; using System.Net.Sockets; using System.Threading; namespace TechUDPBroadcast { class Program { static void Main(string[] args) { const string addr = "224.1.3.99"; const int prt = 12799; UdpClient udpc = new UdpClient(); udpc.Client.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true); udpc.Client.Bind(new IPEndPoint(IPAddress.Any, prt)); udpc.EnableBroadcast = true; udpc.JoinMulticastGroup(IPAddress.Parse(addr)); ManualResetEvent abort = new ManualResetEvent(false); WaitHandle[] evs = new WaitHandle[2]; evs[0] = abort; ThreadPool.QueueUserWorkItem(new WaitCallback(delegate { while (true) { IAsyncResult asy = udpc.BeginReceive( new AsyncCallback(delegate(IAsyncResult iasy) { IPEndPoint rp = null; byte[] recv = udpc.EndReceive(iasy, ref rp); Console.Write("."); }), null); evs[1] = asy.AsyncWaitHandle; if (WaitHandle.WaitAny(evs) == 0) return; } })); ThreadPool.QueueUserWorkItem(new WaitCallback(delegate { for (int i = 0; i < 1000; i++) { udpc.Send(new byte[] { 0x1, 0x2 }, 2, new IPEndPoint(IPAddress.Parse(addr), prt)); Console.Write("+"); Thread.Sleep(1000); if (abort.WaitOne(0, false)) return; } })); Console.ReadKey(); Abort.Set(); } } } The code is simple and has no tricky. UdpClient broadcast datagram every second, another thread receive it asynchorously. When it is running at LAN, sending & receiving are OK. Then i connect the PC to Internet, the UdpClient stop receiving! This happened with or without Windows FireWall. Is this a bug of DotNetFramework? greenxiar Tag: Windows Workflow Visual Designer Tag: 128353

    - gc.KeepAlive - is this the reality of garbage collection Hello, I have a problem with garbage collection. An msdn example says generally the following: I have a class TestCls. With a Property MyProp. Then normally I would write: void MyFunc() { TestCls tc = new TestCls(); int u = tc.MyProp; .... no further use of tc .... } The example says this would not work, because the gc could work (finalizer called) before tc.MyProp has finished. This is a catastroph. The example says I had to write: void MyFunc() { TestCls tc = new TestCls(); int u = tc.MyProp; .... no further use of tc .... gc.KeepAlive(tc); } Think about this, if you have many such objeckts and calls in a method. Furthermore: I have tested the example of the msdn: gc Class/ GcMethodes/KeepAlive Methode which is at ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.NETDEVFX.v20.en/cpref2/html/M_System_GC_KeepAlive_1_b4c5a2da.htm in Msdn VS 2005. I mean the FIRST example. I have a computer with 2 cpus (intel dualcore), but the example does not works as described. So question is it reality? Have I to use in this case (only manged code, no interop) the KeepAlive-Method? (I only mean this sample with pure dotnet, if I use interop the use of KeepAlive is clear for me).

    - How to get the folder name for the Windows recycle bin? Bearing in mind the Windows recycle bin folder has had 3 names since Win 95 up to Vista: x:\RECYCLED (95, 98) x:\RECYCLER (NT, XP, 2000, 2003) x:\$Recycle.bin (Vista) Consider iterating through the the root folder of a drive, and excluding the recycle bin from your results. It is unacceptable to simply ignore folders named "RECYCLED", "RECYCLER" or "$Recycle.bin" by string comparison because, for example, a Vista user may have created their own "Recycled" folder. Is there a set of constants for these folders, or a way of discovering the recycle bin folder for a given volume in .NET? Consider too that the drive might not be local, and may be accessed remotely by system share (e.g. \\machine\C$\) Boz Tag: Windows Workflow Visual Designer Tag: 128323

The problem is that my use of thiese assemblies - wich uses WSE 2.0 SP3 - suddenly throws an exception. We can't find any code changes that should cause this. The exception is: System.UriFormatException: Invalid URI: The Authority/Host could not be parsed. at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind) at System.Uri..ctor(String uriString) at Microsoft.Web.Services2.WebServicesClientProtocol.set_Url(String value) I have varified that the URI supplied is valid. I have also created two test websites, one in .net 1.1 and on in 2.0, running the exact same code as the problem website, and now I find that while the 2.0 test still fails the 1.1 works fine. The exception occurs when creating a WSE proxy for making web service calls to our web services. But there are very similar calls already made before this exception happens. I'm really at a loss here.., we're trying to set up differen testing environments, but nothing has given us any clues yet. The site/code worked fine two days ago, then it stopped working.., what should I do? Anyone?? Is it a problem with using WSE 2.0.3.0 for .net 1.1 under the 2.0 framework? Any workarounds?

    - Jit 64bit Hi all, my team developed an application that partly is .net and uses a win32 dll that we don't want to port to 64 bit. We compiled the .net part of the application telling the compiler to output x86 code. The application doesn't seem to work well anyway since some external assembly doesn't work like expected on WIN2003 x64. I think this external assembly are jitted to 64bit. Can we force the jit of all the program to x86 code? TIA Marco Tag: Windows Workflow Visual Designer Tag: 128301

    - My .NET service dows not stop in a controlled way I developing an application based on some windows services on .NET framework 1.1. Eatch service are a single process service.

    - System.Transaction and MSDTC We are developing a .NET 2.0 based distributed application and use System.Transaction namespace to handle transaction at Business Object level. DAAB 2.0 is used at Data Access Layer level. The database is SQL server 2000 (installed in Windows 2000 server). The .NET server components are deployed in Windows 2003 server. When we attempt to run the application, it throws exception saying â??DTCâ?? service is not running. We are not sure why DTC is a prerequisite for System.Transaction which defeats the purpose of choosing the same. We have also customized the DAAB not to close the connection when the transaction scope is alive but it does not help (This is implemented based on DAAB 3.0). Will system.transaction use DTC by default with SQL server 2000? If so, is DTC a prerequisite in this scenario? There are few articles states SQL 2005 will not require DTC. Any supporting links or inputs on this would help us. Appreciate your help. Thanks and Regards Rasheed Tag: Windows Workflow Visual Designer Tag: 128296

    - ReadOnlyCollection and Multiple Threads I've been really leveraging the ReadOnlyCollection class the last few weeks, figuring that it works exactly as it's name describes. Yesterday I was rudely reminded that reading the documentation for a class is very important, and that making silly assumptions is also bad. It turns out the ReadOnlyCollection isn't readonly at all, and that iterating over it isn't a good thing. I looked all over the Web and various Newsgroups for other people who have run across this, and all of the examples I found were wrong. Many, many people have made the same mistake that I did. http://www.coversant.com/Default.aspx?tabid=88&EntryID=34 In a nutshell: The ReadOnlyCollection class is not thread safe. If a different thread changes the underlying IList<T> then the contents of the ReadOnlyCollection change, and all of the standard threading problems arise. The Documentation says exactly this, so it's simply a case of failing to RTFM. -- Chris Mullins, MCSD.NET, MCPD:Enterprise, Microsoft C# MVP http://www.coversant.com/blogs/cmullins Tag: Windows Workflow Visual Designer Tag: 128276

    - Another Thread Safety Question Hypothetical question: A multi-threaded app has an object with a privately scoped collection (like ArrayList) that is shared between threads. The model is one thread creates/reads/writes/updates the collection, and all other threads read the collection. What are the minimal locks required for thread safety? Is it safe to only lock access when writing/updating the collection? Is it overkill to lock access for all access (including shalllow-copy instance cloning and read-only) in the properties/methods exposed by this object?

    - =?Utf-8?Q?Using_=E2=80=98non_true_type_fonts=E2=80=99_in_d?= I am in the process of upgrading the old legacy application to dotnet 2005 windows application. This is a graphical windows application with various shapes and text strings being put on the bitmap and printed. The problem I am having is, because of the fact that the old legacy system used lots of fonts with custom widths and weight and since dotnet GDI plus does not allowing using â??Non standard fontsâ??. I am kind of stuck at this point. I do not know if any of the below would solve the problem or any other suggestions out there? 1) Create a font using API to GDI and use the Font generated in the dotnet environment. But when tried this approach I got the error message â??Only TTF fonts supportedâ??. So looks like not possible. 2) Create the equivalent TTF fonts for all legacy fonts used and use them in dotnet application. 3) Create an ActiveX on VB6 which returns the equivalent bitmap with the required text and use it in my dotnet application. But not sure what other options I have. Any suggestions are greatly appreciated Tag: Windows Workflow Visual Designer Tag: 128252

    - MsBuild lost some imported namespaces? Hello, I have medium-sized solution in VB.NET (70 000 lines). The project compiles ok under VS2005, without any errors, without any warnings. But when I compile the same solution under MSBuild (from command line), strange things happenes. Compiler executed by MsBuild reports unknown types where it should by known. After whole day of investigation is have found, that imported namespaces are randomly "lost". For example, there is clause Imports System.Windows.Forms in the class file header. But compiler reports DialogResult as unknown type in the same file. When I change declaration of DialogResult to System.Windows.Forms.DialogResult, all is compiled Ok. I must to do these changes 29x in the project. My question is why? It is _exactly_ the same project, which compiles ok in VS2005. The compile line for Vbc.exe is exactly the same (compared from VS2005 build window and MSBuild log file). The build configuration is the same. Not every type from System.Windows.Forms is unknown. Nor System.Windows.Forms is the only one lost, there are similar problems with some of my namespaces.

We are porting a .NET 2.0 program to the compact framework and the application involves the sending and receiving of multicast packets. We noticed that even though the property Socket.MulticastLoopback exists in object browser under "System [Compact Framework]", it complains at compile time that 'System.Net.Sockets.Socket' does not contain a definition for 'MulticastLoopback' According to the MSDN documentation online, this property is supported by the compact framework and we are using the latest service pack of CF2.0. Any ideas? If this property is indeed not included in the CF, how might we configure the socket so that (we have already tried sock.SetSocketOption(SocketOptionLevel.IPv4, SocketOptionName.MulticastLoopback, 1); which throws during runtime) we can allow multicast packets to loop back?

When attempting to login to the site, after a long period of time (about 2 - 3 minutes), "Server Application Unavailable" message is returned. If I switch the provider back to SQLServer everything works fine. If I create a new simple Web Application and just add a Login.aspx page and Default.aspx page, and nothing else, and add a Login Control everything works fine. I successfully receive a formsauthentication ticket, etc.. I setup up the web.config file to use the ActiveDirectoryMembershipProvider and set the appropriate AD connection string (the same string in the first app used) and everything is fine. Differences between the two: The app that does not work uses a SqlRoleProvider, AzMan and SqlPersonlization. Could using any of these cause the problem and error message returned? Has anyone else had any issues connecting a large or complex website with AD using the ActiveDirectoryMembershipProvider? Thanks in advance.
