    - Remoting and DataTypes I'm dealing with remoting for the first time (.net 2.0). I can succesfully call methods that return basic data types (string, bool, etc) but I can't pass more complicated data types (System.DirectoryServices.DirectoryEntry is specifically what I want to have returned). Am I just out of luck or is there something I can do to return that data type? Tag: Window Closure Tag: 136655

    - Hooking IDataObject.GetData in .Net Sorry for the cross-posting. I am having a hard time trying to classify exactly what group this question would apply to. I had posted an earlier message to microsoft.public.dotnet.framework.windowsforms trying to find a way to access the lindex member of the FORMATETC structure for a CFSTR_FILECONTENTS callback request under C#. After some experimenting I was able to come up with the following code snippet that receives the callback with a filled in FORMATETC and allows me to save the lindex value. Unfortunately, I am now stumped at how to forward the callback to the .Net framework copy of IDataObject.GetData so that the request can be processed by the framework and ultimately forwarded to my override of DataObject.GetData. The location that I would want to forward the request is marked as "TODO:". Can this be done or do have I have fully implement my own IDataObject.GetData routine? internal class DataObjectEx : DataObject, System.Runtime.InteropServices.ComTypes.IDataObject { private Int32 m_lindex; void System.Runtime.InteropServices.ComTypes.IDataObject.GetData(ref System.Runtime.InteropServices.ComTypes.FORMATETC formatetc, out System.Runtime.InteropServices.ComTypes.STGMEDIUM medium) { if (formatetc.cfFormat == DataFormats.GetFormat(NativeMethods.CFSTR_FILECONTENTS).Id) m_lindex = formatetc.lindex; // TODO: Forward request on to .Net framework IDataObject.GetData } public override object GetData(string format, bool autoConvert) { // Handle requests for certain formats and then... return base.GetData(format, autoConvert); } } Tag: Window Closure Tag: 136653

    - VS Studio 2005 versus 2008 & .NET 2/3 Hi! We're developing websites with VS 2005 (.NET 2.0) and we want to move on to .NET 3.X (Not the whole team but the R&D team). Do we absolutely need to upgrade to Visual Studio 2008 to do that? Is that the same thing going from 1.X to 2.0? Will we be able to open .NET 2.0 projects from VS 2008 without conversions and still be able to open the same projets with VS 2005? Thank you very much Tag: Window Closure Tag: 136636

    - throttling iocp threads in async server Hello, I'm designing an async socket server and I've read that the IOCP thread pool can overwhelm the System.ThreadPool. I'm thinking about throttling the IOCP threads by only allowing up to MAX connections to be accepted at any given time where MAX is less than the number of threads in the System.ThreadPool. So, for example, if the current number of accepted sockets is N (where N < MAX), accepting a new connection increments N and closing an accepted socket decrements N. If N == MAX, then no more new connections will be accepted until N is decremented. While N == MAX, newly established TCP connections simply queue up in the kernel waiting to be accepted. Does this sound reasonable? Thanks for any help, Marc Tag: Window Closure Tag: 136604

    - Missing Assembly Microsoft.SqlServer.ConnectionInfo while using ClickOnce deployment I'm using vs08 / vb2.0 and am trying to use click once deployment. when I run the click once installation i get the following error msg: "Unable to install or run the application. The application requires that assembly Microsoft.SqlServer.ConnectionInfo Version 9.0.242.0 be installed in the Global Assembly Cache (GAC) first." I have .net 2.0, 3.0 and 3.5 already installed on the target machine and I set the publish status to 'Include' for all required files including this one. In the application files window, I set the publish status to 'Include' on all of this type of files, but in the publish package none of them are included. By the way, under options, I unchecked 'use deploy file extensions incase that was confusing the target machine. Before when this option was checked, all of these files (Microsoft.SqlServer.ConnectionInfo.dll and Microsoft.SqlServer.ConnectionInfo.dll.deploy, and many more) WERE included. However, I still got this error msg. It seems I just can't get past this point. I'm surprised that this is such a big problem and have seen very little info on it.

    - Invalid value for key AttachDBFileName - related to 16-bit calling code ? This thing is complicated so bare with me. We have a pure .NET application using an SQL express database which we deploy via ClickOnce. When we launch the application via the normal shorcuts (internet or program files) it *always* works. Now the beauty is that this application has to be launched from a ***16 bit Delphi 1 application*** (nobody chooses this, neither did we - the 16bit app will live for at least 2 years - and this application is still used by tens of thousands of customers). This delphi application has a plugin mechanisms which enabled us to load 16-bit "add-ins". The short shory is the 16 bit application uses WinExec (exePath,SW_NORMAL) to launch our app. (we have control over the parameters but not over the WinExec part - the first parameter should be an EXE as well) Since the 16-bit app can't call an appref-ms (we launch the appref-ms file in program files\ourCompany\ourproduct as created by ClickOnce and documented in http://safari.oreilly.com/0321197690 ) file directly and since the clickonce application doesn't take program parameters, we have created a man in the middle .NET application (MyBoot.EXE) to do the work for us. It takes the commandline parameters from the delphi app and puts them in a local file for the .NET ClickOnce app. Now listen : - on windows vista it always works - on windows XP it sometimes works (but most of the time it does not) - if I manually launch myBoot.EXE with the commandline parameters then it always works. The question : - is there something different with Windows on Windows for 16 bit applications between XP and Vista or is my Vista machine just faster than all of the XP machines (3) on which I tested this ? - how can I overcome this problem ? (already tried increasing the timeout for the connection string but it doesn't have anything to do with that - is it the switch between 16bit code and 32 bit code? - I've also tried launching the .application file but that doesn't help me either - I've also made the man in the middle a windows application with an application.Doevents to take care of the warnings for WinExec) Thanks for any help, Van den Driessche Willy.

    - .net application using ThinInstall problem... I all, this is my first time that im using google groups so i dont know how it work.. but i'm going to try anyway :P I have build a application on Vb.net 2005 Framework 2.0. That application is for installing a setup of my company on many Notebook of our client's. So like many of you may know Applications .net 2005 need Framework 2.0 to run, and if you are using a .net application on Network ( that is my case ) you need to give all the time permisions on Microsoft .NET Framework 2.0 Configuration for that applicaiton to start on Network ... But i was looking on google to make a stand alone .exe that dont need Framework or the permisions to start on Network .. the name is " ThinInstall" good application ... Anyway i have used ThinInstall , it as "re-compiled my application" and sucess, with works on laptop's without Framework and i dont need to give permisions.. BUT!! , when i try to use my application to Run the setup that my company sell's , the setup open and stay like "block" telling " Teams32 Installing " and stays like that for hours and maybe days... But if i dont use the application ThinInstall to "re- compile" my applicaton the setup works fine.. so i'm guessing that the problem is that the Installer think that i have a Framework installed and then he dont start ? I hope this question is for this topic. Thanks in Advance. Tag: Window Closure Tag: 136546

    - About Component integration I am still new to this component concept, and have read Juval Lowy book about Component programming in dot net. At this stage, I have a question about the concept and the implementation of the component. From his book, it was stated that components can be bought and used by clients applications. The clients application will run the component by calling 'interfaces' (method calls) from components. The book explains about the components interconnections. My question is if the component X and Y were bought from the suppliers (source code might not be included), how could we connect X to Y? I mean I could use or connect my client application to X, and also to Y, but how could we connect X and Y in dot net? Thanks in advance. Han Liong Tag: Window Closure Tag: 136538

    - How to debug:looks like infinite loop somewhere in the guts of .Ne I have a .Net app running on one of my servers. Last night it went in a state where it was no longer doing anything useful.

    - Binary formatting - does it reduce the size ? Hi In a nutshell: how can we produce compact persistant versions of .NET objects? When we first started .NET development five years ago, we opted for TCP/IP binary formatting for performance and network bandwidth reasons. We were revisting some of this work and we noticed that our objects, when saved using a binary formatter aren't shrinking as much as we thought. Has something changed in .NET? For example, we expected the code below to generate quite compact binary file, but it doesn't. And it gets worse for our business objects (they a DataSet as their data carrier) - the binary file contains loads of (verbose) XML!!! using System; using System.Runtime; using System.Runtime.Serialization; using System.Runtime.Serialization.Formatters.Binary; using System.IO; namespace BinaryFormatting_NET1 { [Serializable] public class Foo : ISerializable { string _s; int[] _i; public Foo(string s) { _s = s; _i = new int[1000000]; for (int c = 0; c < 1000000; c++) _i[c] = c; } public void GetObjectData(SerializationInfo si, StreamingContext sc) { si.AddValue("_s", _s); si.AddValue("_i", _i); } } class Class1 { [STAThread] static void Main(string[] args) { Foo foo = new Foo("hello"); string path = @"W:\_Common\MiddleTierFramework\MiddleTierFrameWork.Net2.0\Tools\WinSIPPXmlCleanerTests\BinaryFormatting_NET1\foo.bin"; BinaryFormatter bf = new BinaryFormatter(); FileStream fs = new FileStream(path, FileMode.Create); bf.Serialize(fs, foo); fs.Close(); } } } Tag: Window Closure Tag: 136532

    - Dimiensioned Measurement There is now a robust java library solution I've been reading about called jscience (http://jscience.org). Is anyone aware of a similar effort in the .net community? The library supports consistent handling of measurement and conversion between quantities of the same dimension in just about every international standard (SI) and non-SI unit of measurement in such a way that the compiler facilitates design time checking. I'm in need of a few quantity types to deal with some common dimensions of measurement in business, with Money being at the top of the list, and Duration & Length following. Barring an effort along the lines of jscience, any links to code samples that do this would be much appreciated. TIA Eric Tag: Window Closure Tag: 136528

    - Architecture and Design Question for C# webapp I am designing a system which will have a C# backend and an ASP.NET frontend. My question is about how I would best design the application. The first way that I am considering doing it is writing a data access layer as part of the App_Code directory inside the webapp which would just compile and run with the app. The second option would be to create a server process that interfaces with the database and then have the web frontend communicate with the server process by an IPC method (most likely WCF). It is likely that this application will have to support a large number of concurrent users if that has an effect on the method selected. Any input would be appreciated, a pros/cons list would be great if somebody has that much time. Thanks in advance! Tag: Window Closure Tag: 136524

    - Domain Policy for CAS? All, I have a user control that requires FullTrust to run. I have embedded it in a web page. If the Machine CAS properties are set to FullTrust for the given server, everything works fine. I can set FullTrust for this server because I am the Administrator of my machine. But what if I were not? How would I be able to run my user control in IE? It would be nice if my domain administrator could set a policy stating that "Server XYZ may have full trust" for all of the systems on the Domain. Is this possible? I tried playing with the Enterprise settings in the CAS tool, but this does not seem to work for me. I need to set it at the Machine level for it to work! I understand that this is because the CAS system takes the strictest settings of all three zones (Enterprise, Machine and User) and the Machine level contains an IntranetZone which does not have FullTrust. Further, I tried playing with the User settings, which the individual users have access to modify, but it STILL doesn't work... probably for the same reason. Am I missing something? Can a Domain Administrator give machines on the network access to my Intranet app? Thanks, Brian Tag: Window Closure Tag: 136514

In the design document I received, I have to create the following : "Load the assembly, get the configuration user control, display the user control... When the user control is not needed anymore, unload the assembly."... I can load the assembly (in a different appdomain), I can get the user control, I can unload the assembly (by unloading the appdomain), but I can't display the user control because I receive an exception (which I don't really understand) : "Remoting cannot find field 'parent' on type 'System.Windows.Forms.Control'."... How can it not find the field 'parent'? Is there a way to make it work? I can't believe MS didn't think about this possibility which is used in about all "plugin based" application, so there must be something I'm missing.

    - Appdomain cannot load assembly... why? Hi, (My code is at the end of this post) I have an AppDomain that must load a simple assembly that has only one class with one method and it does not work... I receive this exception : "Could not load file or assembly 'ModuleLoader.dll' or one of its dependencies. The system cannot find the file specified." Does anyone have an idea of something I'm missing? Thanks ThunderMusic [Code] *** Main App (calling method) *** AppDomainSetup ads = new AppDomainSetup(); ads.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory; ads.PrivateBinPath = AppDomain.CurrentDomain.BaseDirectory; ads.DisallowBindingRedirects = false; ads.DisallowCodeDownload = true; m_CurrentMonitorAppDomain = AppDomain.CreateDomain("MonitorLoader", null, ads); // The following call fails MonitoringModuleLoader mml = (MonitoringModuleLoader)m_CurrentMonitorAppDomain.CreateInstanceAndUnwrap("ModuleLoader.dll", "ModuleLoader.MonitoringModuleLoader"); *** The "ModuleLoader" library *** namespace ModuleLoader { public class MonitoringModuleLoader : MarshalByRefObject { public MonitoringModuleLoader() { } public MonitorBase Load(byte[] LibBytes, string ModuleName) { return null; } } } [/Code] Tag: Window Closure Tag: 136490

    - Linq to Sql Updates In all the samples that I have seen to update a table using Linq to Sql, this is the type of code given: public static void UpdateProduct() { NorthwindDataContext db = new NorthwindDataContext(); var product = db.Products.Single(p => p.ProductID == 1); product.#PropertyName# = #NewValue# db.SubmitChanges(); } In the "real world", a Product would be retrieved and sent to the client (say using WCF), the client would make a change to one or more properties, and would then pass back the Product to the server. So, my question is what code is required to save the Product back to the database? I can see that the following would work but there must be a better way... public static void UpdateProduct(Product updatedProduct) { NorthwindDataContext db = new NorthwindDataContext(); var product = db.Products.Single(p => p.ProductID == 1); product.#Property1# = updatedProduct.#Property1# product.#Property2# = updatedProduct.#Property2# product.#Property3# = updatedProduct.#Property3# product.#Property4# = updatedProduct.#Property4# product.#Property5# = updatedProduct.#Property5# product.#Property6# = updatedProduct.#Property6# db.SubmitChanges(); } Is there a way to link the passsd in Product with the DataContext and therefore just call SubmitChanges without having to re-query the database first?

    - Versions of .NET framework I have noticed that my Windows XP laptop has both version 1.1 and 2.0 of the .NET framework installed (as well as hotfix KB928366 for version 1.1) compared with another similar computer that only has version 2.0. Is having both versions likely to cause me problems? Can I uninstall version 1.1 safely? I started to uninstall the hotfix but it gave me a warning that version 2.0 might not work so I stopped. I'm trying to tidy up my Windows installation because I am having trouble getting the Adobe website (www.adobe.com) to work properly (e.g. whenever I try to go to the Flash version test page it times out and getting to other pages only works sometimes!). The laptop with just version 2.0 of the framework is able to get to all the adobe web site pages every time. I am therefore trying to eliminate all differences between the two computers.

    - How to stop a paint event handler function by another event Hi there, I'm working on a stress test tool for drawing. After start button clicked, it fires Form_Paint(xxx) event handler to continuous drawing shapes on screen. Problem is once there is a while loop in the event handler, so once entering the loop, no other event can capture from application. I tried to use a thread but it causes another problem that e.Graphics will be out of scope, and raise an exception. Below is my brief of my code. Could any one tell me how to make solve this problem? Thanks. private bool bTesting; private void drawPage(Graphics g) { // do something draw... } private void Form_Paint(Object sender, PaintEventArgs e) { // skip while(this.bTesting) { drawPage(e.Graphics); } } Tag: Window Closure Tag: 136465

    - rsearch suggestions I would like to have suggestions on how I could setup the following applications: Questions about creating an .net â??executableâ?? 2005 that will not remained installed once a user enters some data into the application. I also want this applcation to not require any previous software installed on a users workstation. I basically want to setup an application for new users when they are applying for insurance. This application would preferably be a run as a windows desktop application versus on the internet. Once the user enters the save or submit button, I want the application to send the data back to be processed on a Sql server 2000 or sql server 2005 database. I have Visual Studio.net 2005 currently and would like suggestions on how to do steup this type of an application using Visual Basic.net 2005. Thanks! Tag: Window Closure Tag: 136455

    - Process space problem in C#.NET I have two C#.Net projects, both of which create instances of the same C# class from a separate assembly; the class creates its own thread. When either project is run alone, it works correctly. However, when they are run simultaneously, I get a threading error (from System.Threading.ThreadHelper.ThreadStart_Context) in the project that starts last. Don't C# .Net programs run in their own process spaces? Does the fact that they both instantiate the same class from the same assembly mean that the process space is shared? Thanks for any ideas on this. Tag: Window Closure Tag: 136454

    - Help needed compiling with CSharpCodeProvider. Hi there, I am using the CSharpCodeProvider to compile some cs source files from within a console app. The source files contain partial classes and methods so I need to use the v3.5 compiler which I do with the IDictionary constructor. However I get the error "Compiler executable file csc.exe cannot be found." If I do not force v3.5 then I get an error related to the partial methods. How can I provide the correct path to csc.exe? It is definately installed - The code builds fine from within VS. The machine is Vista x64 with vs2005, vs2008RTM - it used to have vs2008 beta2 - I wonder if the path is still pointing to that but I'm not sure how to find out.. Any pointers would be appreciated.. cheers jd Tag: Window Closure Tag: 136437

I've been having a problem where open windows when I'm about to do something
just disappear. The screen will almost refresh and the window I was working
in will have closed or disappeared. It's possible it's a virus but I've
scanned my computer with Panda and nothing comes up. Appreciate any help that
can be offered.

Ask your question in a group dedicated to your Windows version if you want
answers. This
is a .NET programming group.

To find an appropriate group:

http://www.microsoft.com/communities/newsgroups/en-us/default.aspx?guid=1080912A-26C5-7040-AFDD-2224A4FEB3EA

Select your language from the Tree View on the left, then scroll down to
Windows. In the Windows category, open the node for your version of Windows
and find an applicable
group there.

When you do post again, provide important details, such as the Windows
version and patch level, any recent hardware or software changes to your
system, etc.
