    - I miss those old events in this brave new world! This is just a comment. I was very surprised to find out that there are no named events support in .NET framework! Sure, mutex objects can do most of IPC work, but there are some cases that mutexes do not fit in (because mutexes have a unique thread ownership feature). For example (this may be very hard to understand, just like all other synchronizing problems): 1. A parent process spawns a child process to do a job. 2. The parent has to make sure that the child starts the job or the child exits prematurely on errors. It also has to have a way to tell the child to stop working. 3. So in this brave .NET world, I have only one choice - two mutexes for the IPC. One is for 'quit' signal, the other is for 'error' signal (when errors occur, the child process exits). 4. Now the parent has the following logic: get_unique_signal_names(); // Guid is used create_quit_signal(); // intially owned create_error_signal(); // not initially owned; create_child_process_config(); // create a config file for the child process create_child_process_with_config(); // spawn the child process with created config file wait_for_child_process_or_error_signal(); // wait any of them if(process exited) { call_error_handler(); } else { user_ineration(); // provide UI to let user stop child process } 5. The child process does this logic: get_signal_names_from_config(); // they are in app.exe.config open_quit_signal(); open_error_signal(); try { intialization_for_job(); } catch(error) { set_error_signal(); return -1; } start_job(); // e.g., starting a listening socket wait_for_quit_signal(); // enter wait state; 6. Everything is fine, right? But there is only one *small* problem. This problem is caused by the unique feature of mutex objects - thead ownership. Simply put, the above logic does not gurantee wait_for_child_process_or_error_signal() always indicate the correct situation. The error signal is created not owned. Since no thread has ownership of this mutex, its state is always *signaled*; unlike event objects, they are either signaled or nonsignaled. So it is not 100% safe that when the code gets to wait_for_child_process_or_error_signal(), the child process has already does open_error_signal()! It took me hours to find out this *small* problem. I think it's a small problem because programs now runs on fast computers, the chance is very rare for the child process get choked before open_error_signal() and while the parent process gets to wait_for_child_process_or_error_signal(). 7. There is a solution. But it is clumsy (anyone who gets to this point please point out a good way if he/she know one): For the parent process: for(;;) { Thread.Sleep(500); // don't exhaust CPU time // wait for the child process to get ownership of this signal if(done_signal.WaitOne(500, true)) // in case the child already has it { done_signal.ReleaseMutex(); // well, have to do get/release in pairs } else break; } For the child process: open_error_signal(); get_ownership_of_error_signal(); // get ownership - a simple wait 8. That's why I miss those named events in the ugly old world. With named events, I don't have to add the logic in note 7. At last, I finished it. I thank for any explanation on why named events extinct in the new world (except the performance issue). Tag: const byte[] ? Tag: 93740

    - Should I use XML or not? Hello, I am writing a word add-in in C#. This add-in has to attach some metadata to bookmarks in the document. = The metadata is stored in Word document variables. Typical metadata can consist of a string identifier, three lists of [0 = to 50] person-names each and about 5 Yes/No flags. The problem is that I have to parse the metadata whenever the user moves = the cursor onto bookmarked text so it has to be very fast, otherwise = moving through the document will feel sluggish. I was thinking of formatting the metadata using XmlTextWriter and = parsing it using XmlTextReader. However, I am not familiar with these classes and I am afraid that this = approach may prove too slow on computers that are not state of the art. The alternative is formatting and parsing the strings myself, perhaps = using some combination of string.Split, string.Join, string.IndexOf and = StringBuilder. Since the metadata is only intended for the internal operation of the = add-in, it can be as ugly as I want (in fact, I was thinking about = obfuscating it do discourage users from messing with it but this may add = another slowdown). What would you suggest? Thank you, Alex. --=20 Please replace myrealbox with alexoren to reply by email. Tag: const byte[] ? Tag: 93734

    - CreateProcessWithLogonW doesn't work with XP service pack 2 I posted this in another group, so, sorry if you have already read this. I'm trying to run an application under another user within a winform app writen in C#. I have tried a number of different things, but it seems that the CreateProcessWithLogonW function should work to do what I need to do. This appears to work just fine in Windows 2000 and XP with service pack 1, but it doesn't work with XP service pack 2 installed. I'm sure it's one of the "Enhanced security features" of service pack 2, but I can't seem to get this to work. The function returns a 1 indicating that it worked fine, but the applcation that I'm trying launch does not launch. To give a little background on what I'm doing: I have written a small app that is basically just an interface for the netsh command to change network setting for the user. The users do not have admin rights on their machines, but a select few need to be able to change their IP addresses for buisness reasons. Because of this, I basically just call the CreateProcessWithLogonW function to start run the netsh command under an admin account on the machine to change the IP address to whatever the user specifies in the interface that I provided. As a test, I have created two very simple windows apps. The first one calls the CreateProcessWithLogonW function to login as another account on the machine. It then calls another simple application that uses the WindowsIdentity to show the current user. This works fine on Win2K and XP sp1, but not with service pack 2. If anyone know how to get around this, that would be great. Thanks, Jerry Tag: const byte[] ? Tag: 93730

    - System.Collections.DictionaryBase.GetEnumerator cannot be overload Hello, I've tried to write an method overriding System.Collections.DictionaryBase.GetEnumerator(), but my C# compiler (VS .NET 2003) outputed 'error CS0506'. This means System.Collections.DictionaryBase.GetEnumerator() is not virtual one, but in the .NET class library reference, it is described as 'public virtual IDictionaryEnumerator GetEnumerator();'. Also, the object browser in VS.NET 2003 says DictionaryBase.GetEnumrator() is 'public virtual new System.Collections.IDictionaryEnumerator GetEnumerator ( )'. Is this a bug of the compiler or the document? Or Is there something wrong in my understandings? Tag: const byte[] ? Tag: 93725

    - Question on - Automatic compilation of VB.NET files on a Web Server Not sure if this is the correct newsgroup. Could be the IIS. Hopefully someone can answer my question. We are migration an ASP Web App to VB.NET. One of the benefits we're enjoying so far with ASP is that we do not have to worry about a build release. When an ASP file is modified and tested, we just deploy that file to the production Web server through Visual SourceSafe without worrying that we are releasing someone elses untested/unfinished code out. Now I am hoping that .NET provides the same scenario where all we need to do is copy the .aspx and .vb files to the Web Server, and all the .vb files would automatically get compiled into the assembly when an .aspx file is requested. Meaning that we wouldn't have to compile the application into a DLL assembly. The environment would recognize that the .vb file has changed and would get compiled into the existing assembly. My question, does .NET work this way? Thank you. Tag: const byte[] ? Tag: 93724

    - Web Browser control throws exception when trying to navigate to ur I have written a small app to help test code generated by Xslt tranformations, these transformations are performed by various components - basically this is a test rig for the components and Xslt they use. All works fine the first time I invoke the method, save the output to file and then browse to this file with the browser component. However, if I do the same action again I get a "Exception has been thrown by the target of an invocation." exception thrown when calling the Navigate() method (passing in the same url as worked previously). The InnerException is "The requested resource is in use.". If I change the tool to point to a different component/xslt each time I invoke the test then all is OK, it is just doing this when I do the same url twice in a row. I suspect it may be something to do with the some resources referenced in the html not being available and the browser control not being ready for use again - but why would it work for a different url? Please help!!! Thanks -------------------------- Shaun Venus emailid: sunevnuahs domain: hotmail.com -------------------------- Tag: const byte[] ? Tag: 93720

Right now, we open the com port and ship out our text printer data to that port (a label printer).

    - Plugin assembles best practices This is a lengthy post; please bear with me... This will be a large system with dozens of plugins. In addition to plugins developed internally there will be 3rd parties that will write their own and integrate them into our application. I will be managing the identification and loading of these plugins. In addition, there are a number of assemblies that plugins will reference, some shared, and others private. There are a couple of approaches I am considering. It is expected that all plugins will need to be registered so that the app does not blindly load up all assemblies searching for plugins to load. FIRST OPTION - separate directories The expected directory layout is like this... BaseDirectory (application) PluginManifest.xml (info on which ones to load) | | -- Common (shared.dll, all versions forced to latest) | | -- PlugIn1 directory (Plugin1.dll, private1.dll, v1.0) | | -- PlugIn2 directory (Plugin2.dll, private1.dll, v1.1) | | -- PlugIn3 directory (Plugin3.dll, private1.dll, v1.2) All assemblies that share types are to be relocated to the common directory. This occurs when the assembly is installed. This involves determining if an assembly is intended to be shared - this implies that the assembly is exporting a type that the consumer of that assembly (i.e. the plugin) is also exporting or importing. All shared assemblies will have binding redirects so that all other assemblies will all be pointing at the same one. All assemblies that are intended to be private will remain in the subdirectory of the plugin. A codebase hint for each assembly to be loaded will be placed into the app.config file so that the assembly lives in the fusion load context. ALTERNATIVE: Put all assemblies into the same directory and enforce a naming convention like this... <namespace>.<asmName>.<version>.dll This is intended to result in all assemblies having a unique name; the name to include the assembly version number. No binding redirects to be done, nor will codebase hints be used, unless there is a common assembly that all others must share. This will be identified manually and a binding redirect put into the app.config file. The layout looks like this... BaseDirectory PluginManifest.xml (info on which ones to load) | shared.v1.0.dll, shared.v1.1.dll, shared.v1.2.dll, | | PlugIn1.dll PlugIn2.dll PlugIn3.dll private1.v1.0.dll private1.v1.1.dll private1.v1.2.dll PROS and CONS: Separate directories. PROS Prevents clutter. Makes it easier to separate "system" *(i.e. our) assemblies from addins, 3rd parties, etc. Ensures that all private assemblies remain that way as they are isolated by directories. There is no global naming scheme we need to maintain or enforce. Each plugin can have separate associated data files. Can use its own subdirectories. No naming conflicts. CONS Much more overhead in managing the system. I have to write a fusion-like layer to handle all the locations that assemblies can be in, the binding redirects, etc. All plugins need to be analyzed for common items during the registration process. One directory PROS: Has the advantage of simplicity. Easy to locate and load assemblies. No fusion-like layer to manage the assemblies is needed. CONS Requires a global naming scheme that everyone must adhere to. Each plugin may be using a different version of an assembly and there is no way to tell which one is using what since they are all located in the same directory. Identifying conflicts will be a nightmare. If an assembly accidentally exports a type that is supposed to be private will result in an error (typecase) that will be very hard to troubleshoot. Will be hard to "know" what assemblies are actually used and needed. Clutters the directory. If a plugin uses a data file may result in a name conflict with another plugin. So, anyone have any comments? Which method would be best? What other methods are there that I did not mention? Thanks, David Levine Tag: const byte[] ? Tag: 93694

    - Web-Service/COM+ components and object-oriented concepts Hi, I often read that it were a good practice to implement a business logic tier as a Web-Service or as a COM+ component. While I understand the reasoning concerned with scalability and support of non-.Net clients etc., I'm a bit confused about how the concept of object- oriented components goes along with these. Usually, I would prefer, for example, to have a reference to a "customer" instance, that has an associated "shopping- list" instance, to which I may add items, over a function like "AddItemToShoppingList( customerId, itemId )". What's even more important, I would like to implement the corresponding business logic the first way. As far as I understand, it is not possible to have consecutive calls against the very same instance exposed from a Web-Service or COM+ component, so this seems to mandate procedural mechanisms. Now, for Web-Services I would think that since you have a session context, there's not so much problem with that, cause the "I do have my own history" instances can be kept in the session state, like one does in ASP.NET applications. But for COM+, I don't see a way to achieve this (ok, I may could come up with some scheme, but that would not be "intrinsic" to the technology in use). So, is this advice about implementing business logic within COM+ components somewhat "misleading", or didn't I just get it? Thanks in advance for all comments! Martin Tag: const byte[] ? Tag: 93671

    - Need XPath to invalid element being validated by XmlValidatingRead Hello, I have an xml document that I'm validating against a schema using the XmlValidatingReader. I've attached a callback method to the ValidatingEventHandler so I get notified of the validation errors. This is all working fine. I have the following 3 files: 1. collar_default_vals.xml - contains correct default values for all elements. 2. collar.xml - contains specific values ( this is being validated against schema ) 3. collar.xsd - the scheam used to validate the collar.xml. When validating collar.xml against collar.xsd I need to know the full path( XPath ) to the element in collar.xml for which validation fails because I will need to replace that invalid value with a default value stored in collar_default_vals.xml. The problem is that collar.xml contains nested elements ( complextypes ) and some of the elements have the same names. So even though I know the name of the element that fails validation I don't know exactly which element it is. Is there a way to get the XPath to the element that is failing validation? Any ways around this? Thanks. -Kishore Tag: const byte[] ? Tag: 93655

Unfortunately, VS locked soon after, brought the app down with it, and the machine was rebooted. I don't have any other machines around here that have been running for > 25 days to further test the observation. So the question is: does TickCount wrap to Int32.MinValue (and the documentation is wrong) or to 0 (and I was mistaken in my observation) ? Thanks Lionel Tag: const byte[] ? Tag: 93651

    - proper way to update a datagrid from a separate thread (bringtofront error vs versionnotfoundexception) i have a datagrid that i need to be updated every couple seconds in a point-of-sale type application. i thought this was going to be easy but apparently its not. i have a simple sql query to select a few columns from a table and i want these to end up in a datagrid. first time around i had a thread doing a fill as follows: Dim da As New SqlClient.SqlDataAdapter("select c.clientid ,c.balance,c.connected,isnull(ac.security,0) creditid from client c left join acctcredit ac on ac.creditid=c.creditid", sqlConn) m_DataSet = New DataSet da.Fill(m_DataSet, "Client") Form.BeginInvoke(CallDataBindToDataGrid) where calldatabindtodatagrid is: Form.DataGridClients.DataSource = m_DataSet but the result of that was that whenever the datagrid refreshed it both reset the scroll position, and more important the form would be brought to the foreground as if bringtofront was called which caused major problems and so this was obviously unacceptable. for my next try i decided to just access the datatable directly with the following code every period: Me.DataTable1.BeginLoadData() For i As Integer = 0 To DataTable1.Rows.Count - 1 DataTable1.Rows(i).ItemArray = DirectCast(ar(i), DataRow).ItemArray Next Me.DataTable1.EndLoadData() Me.DataGridClients.Refresh() but every so often this gives me an exception versionnotfoundexception "there is no original data to access" which i have yet to be able to find a workaround/fix for. its often enough that i'm working on a saturday morning to fix it. so far my google's/newsgroup searches have found alot of other people with the same problem but apparently no way around it. so rather than keep on trying to fix specific errors or experimenting with different ways of updating the datagrid, i ask: what is the right way to do this. my goal is simply to have datagrid1 update every couple seconds in a background thread. im still amazed how difficult this has proven but hopefully im just missing something major and someone can point me in the direction. thanks for putting up with the rather long and rambling post too.

    - SQLServer State - how do you use it? Hi - I am regularly losing session information, I think due to the worker process recycling. I have been traditionally using InProc procedures, and using them like: Session("username")=objDR("username") 'read from database ..and then simply referencing this on any other pages code behind, as: if Session("username")=..... If the proces recycles while a customer is browsing, I lose all their information (sort of web cart), they have chosen so far. So, will changing to SQLServer state stop this? Can I use SQLServer state with MSDE? Do I have to make any fundamental changes to the way I read and declare session variables? (ie. I keep hearing about serialization - does this change the way I use the sessions, as above)? I am using a single web server (MS 2003 Web Edition), with MSDE, and 512MB Ram. I've changed a local version of my app, to use SQLServer State (please see my local web.config below) - and it APPEARS to work ok, but because I've made no change to the way I use the sessions, are they still using the old way of working - ie. are the sessions still being stored in the web server memory? Sorry for my ignorance, but I really want to learn best practice. Thanks, Mark Web.config: <sessionState mode="SQLServer" sqlConnectionString="data source=127.0.0.1;user id='sa';password=''" cookieless="false" timeout="20" /> *** Sent via Developersdex http://www.developersdex.com *** Don't just participate in USENET...get rewarded for it!

    - WinXPx64 question Hi, I have a question regarding the .NET Framework 2.0 and x64. I realise these are still in beta, but I hope someone can help me. If i had dotnet2.0x64 installed on winxpx64. Does an application compiled on a winxpx86 (using dotnet2.0x86) require the x86 or x64 edition of dotnet2.0? I'll try to rephrase that a little better just in case you didn't get it. Does a 32bit .net application require the 32bit .net framework edition, or can it use the 64bit .net framework edition? Thanks guys, Tim. Tag: const byte[] ? Tag: 93628

    - A Bug in Visual Studio ? I am unable to solve the problem. Any help is appreciated. Is this a bug? Summary : I am raising a custom shared event from custom DateTimePicker instances. This custom event causes to a call to MessageBox.Show. At that point splash screen form which is the starting point of applicatioin pops up. Details: I have a winforms application, Vb.NET. I implemented a custom DateTimePicker and overrided the OnFormClose method. Custom DateTimePicker has a shared event "UnpermittedDate" . This event is raised at overriden OnFormClose Method of custom DateTimePicker. One of the windows forms handles the shared event raised by each custom DateTimePicker as follows; Private Sub CustomDateTimePicker_UnPermittedDate() MessageBox.Show("End date must be after begin date") End Sub To problem is whenever this messagebox pops up, the splash screen which is the starting point of application pops up too.

    - NotifyIcon and Service I'm trying to set up a simple service, and am trying to get an icon to show up in the system tray, along with tooltip, context menu, etc. I added a NotifyIcon control to my ServiceBase subclass' component tray, set the properties I need, and everything seems to be in order. All code in the service at this point is that generated by the IDE. Upon running, however, I get this exception... An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll Additional information: Exception has been thrown by the target of an invocation. ...at this line in InitializeComponent(): this.notifyIcon.Icon = ((System.Drawing.Icon)(resources.GetObject("notifyIcon.Icon"))); Is there a different best practice here or perhaps some misconfiguration?

    - nested message pump While processing some event, I want to enter nested message loop (so like I called Application.Run, but it cannot be called twice), which is to be terminated from another event handler. Say, write a function that shows TextBox, waits for user to enter the text and press return, then returns entered text. I'd like to ommit modal dialogs, it would be really nicer to do it in child control, without new Form. Tag: const byte[] ? Tag: 93607

Hi group

How i can do that ?
public const byte[] B = new byte[] {0x01,0x02,0x03}

// compile error : expression must be constant.
I try a other declaration, but no results.

for the moment i make it readonly, but it is a little different ...
thanks

You can't.
