    - Dirty property value persist problem in asp.net custom control Hi, I created a custom control, and encountered a dirty property value persistence problem. I created a property with a custom class type, call SQLSettings which holds the SQL connection parameters, the class as follows: public sealed class SQLSettings { private string serverName; ....... public SQLSettings() { this.serverName = string.Empty; ...... } [NotifyParentProperty(true)] public string ServerName { get { return this.serverName; } set { this.serverName = value; } } .................. And, I also created an mapping TypeConverter and UITypeEditor classes to handle the design-time founctinality. The property I created in my conbtrol as follows: [BrowsableAttribute(true)] [CategoryAttribute("Behavior")] [BindableAttribute(true)] [NotifyParentProperty(true)] [EditorAttribute(typeof(SQLSettingsUITypeEditor), typeof(UITypeEditor))] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] [TypeConverter((Type)typeof(SQLSettingsTypeConverter))] [PersistenceModeAttribute(PersistenceMode.InnerProperty)] public SQLSettings SQLSettingsData { get { return this._sqlSettings; } set { this._sqlSettings = value; } } They all works fine when first set value to this property, I can see the persisted data showed in .aspx file. When I go back to design view and update the property value via my UITypeEditor, I can see the value already updated in VS.NET properties browser. But when I turn to see .aspx file in code view, I didn't see the dirty property value updated in .aspx file. When I turn to design view, the updated property value is lost, it remain keep the first persisted value. How about to solve this problem? Any idea? Thank you for your kindly help.

    - WebRequest Exception: "The attempted operation is not supported for the type of object referenced" We have written an asynchronous download class that uses the WebRequest to perform downloads. Things are working fine in-house, and it's fine for the vast majority of our users, but there is an increasingly large of people who are getting the following exception: Exception Type: System.Net.Sockets.SocketException ErrorCode: 10045 SocketErrorCode: OperationNotSupported NativeErrorCode: 10045 Message: The attempted operation is not supported for the type of object referenced Doing a search on that phrase ("The attempted operation is not supported for the type of object referenced") almost immediately led me to this page: "How to determine and recover from Winsock2 corruption" http://support.microsoft.com/kb/811259 Using the instructions on that page has worked for 100% of the users with the problem! At first I though, "Great!" But now we're seeing a lot of these, and I'm starting to think that since it's not that isolated, it might not really be a true "problem" on their machines. It might be a firewall program or some other incomptaibility. Have other people seen this before? Do you know of something "innocuous" that could be causing the SocketException? Any hints, guesses, or shots in the dark would be greatly appreciated. Many thanks, Taylor Tag: .NET Codesnippets Tag: 120817

    - Cannot create ActiveX object (on Windows 2000) I have made a small interop function that uses Acrobat Distiller. It works smothly on all the XP machines, but when I try to run it on a Windows 2000,I get this error: System.Exception: Cannot create ActiveX component. at Microsoft.VisualBasic.Interaction.CreateObject(String ProgId, String ServerName) at MediaBuilder.Utils.PDFCreator.PDFCreator.Main(String[] args) in C: \Visual Studio Projects\Utilities\PDFCreator\Main.cs:line 31 And line 31 looks like this: objDist = (ACRODISTXLib.PdfDistiller) Microsoft.VisualBasic.Interaction.CreateObject ("PdfDistiller.PdfDistiller",""); What is the difference between running this under XP and 2000? The odd thing is, that I can compile it with out errors on the 2000, it is just when I run it, I get this error. Could it be because of the call/use of Microsoft.VisualBasic.Interaction.CreateObject, that should work W2KSP4. I have also tried DCOM configuration (http://support.microsoft.com/kb/q183607), but even with even with this, I still get the error. Tag: .NET Codesnippets Tag: 120814

    - Problem with ColorDialog and MenuStrip Hi, problem #1 : I have a MenuStrip on my Windows form and it doesn't get painted (is transparent) unless I move the form... Anyone ever encountered this? Anyone knows what could cause it? problem #2 : I want to make a ColorDialog appear, but everytime I want to show it, it appears behind my form so I have to go to another application and go back to my application to see it. Is it a bug? Here's the code (can't be simpler) ColorDialog cd = new ColorDialog(); cd.ShowDialog(); Can anyone help please?!? These are the last two known bugs in my application.

    - MSIL Inquiry involving boxing Hi, I'm following a tutorial and they translate this C#: object[] a = {1, "Hello", 123}; to this IL: .entrypoint .locals (class System.Object[] V_0,class System.Object V_1,class System.Object[] V_2,int32 V_3) ldc.i4.3 newarr [mscorlib]System.Object stloc.2 ldloc.2 ldc.i4.0 ldc.i4.1 stloc.3 ldloca.s V_3 box [mscorlib]System.Int32 stelem.ref ldloc.2 ldc.i4.1 ldstr "Hello" stelem.ref ldloc.2 ldc.i4.2 ldc.i4.s 123 stloc.3 ldloca.s V_3 box [mscorlib]System.Int32 stelem.ref But when I compile similar code, I get a big difference. Instead of putting the integers in a local variable, they are stored directly and boxed via: IL_0006: stloc.2 IL_0007: ldloc.2 IL_0008: ldc.i4.0 IL_0009: ldc.i4.1 IL_000a: box [mscorlib]System.Int32 IL_000f: stelem.ref IL_0010: ldloc.2 IL_0011: ldc.i4.1 IL_0012: ldstr "Hello" IL_0017: stelem.ref IL_0018: ldloc.2 IL_0019: ldc.i4.2 IL_001a: ldc.i4.s 123 IL_001c: box [mscorlib]System.Int32 IL_0021: stelem.ref The big difference is that the number is pushed directly on the stack and boxed, rather than the number going into a local variable and the address being pushed and then boxed. So 2 questions: 1) Why would there be a difference? I tried both 1.1 and 2.0 compilers, but can't seem to get the ldloca.s version? 2) The more interesting question is how does the box instruction work on a "transient pointer?" Here's the interesting segment: ldloc.2 <- push address of array ldc.i4.0 <- push index 0 ldc.i4.1 stloc.3 <- store number one in local integer variable V_3 ldloca.s V_3 <- Put address of local variable on stack box [mscorlib]System.Int32 <- I guess Box will be able to work with the address??? and make a box based on the dereferenced address? stelem.ref For those curious, the tutorial I'm following is: http://www.vijaymukhi.com/documents/books/ilbook/chap12.htm And do a search for the text "It is in stelem.ref and we are not privy to this code". (It's the following example, after this text) Thanks all... -Ben Tag: .NET Codesnippets Tag: 120812

    - HttpModule not working with GAC Hi All, I am facing this strange problem here. I have created a custom HttpModule to filter the response. It worked fine when i tested it as a part of my existing project. But when I created a new project and got a dll after strong naming it and putting into GAC, it wouldn't work any more. I have added a new entry in machine.config under <httpModules> tag to make it filter each asp.net response. But I have no clue why its not workig now. Any help would be highly appreciated. Thanks.

    - 'System.InvalidOperationException' An unhandled exception of type 'System.InvalidOperationException' occurred I am getting this error when running the built executable directly from the bin folder -- however, it doesn't show when I run from within the IDE (Debug). I've not tried it using Release - as I'm not wanting to "fix" the problem inadvertantly simply by switching modes (if that makes sense). I'm seeing lots of posts regarding this, but all seem general - and none of them, that I found, relate to running under the IDE vs the EXE. I sent the EXE to a collegue who seems to be able to run it just fine. I'd like to find out what it will take to get it working on my dev box, as I'm sure the first customer we install this on will have the same problem (don't ask me how I know, I just do -grin ) Help?

    - Diagnosing System.IO.IOException I have an application that generates and moves 1000s of small text files. Every so often for some unknow reason I start to get the following 2 exceptions: System.IO.IOException: Not enough quota is available to process this command. at System.IO.Directory.GetFiles(String path, String searchPattern) and (if the first exception does not happen we get a bit further and try to move the files we found) System.IO.IOException: Insufficient system resources exist to complete the requested service. at System.IO.File.Move(String sourceFileName, String destFileName) I can see no problems with available memory, the app does not use huge chunks of resources as far as I can tell from taskman and process explorer, restarting the application clears the problem. Load on the app does not seem to cause it as I can hit it VERY hard and it does not fail.. this leads me to think it is down to another application or the OS. Has anyone else seen this or got any good ideas on how to track the cause? Tag: .NET Codesnippets Tag: 120789

    - system.badimageformatexception returned from custom installer I have a web project that I have converted from VS 2003 to VS 2005. The installer is configured to use detect a newer version and if found to uninstall the old version before installing the new version. The installer in the new version VS 2005 contains custom actions that are compiled with VS 2005. For launch conditions, I have configured the .NET Framework to be at 2.0.50727 and Allow Later Version si set to True. When I run the installer I receive the system.badimageformatexception which references the dll that contains the custom installer code. If I uninstall the 2003 version of the software and then do an install of the 2005 version everything works fine. But if I have the 2003 version installed and then run the installer for the 2005 version I receive the error about the bad image. Is this a bug? Am I doing something wrong? Are there workarounds? Will my customers have to uninstall the old version manually before installing the new version? Thanks, Leslie Tag: .NET Codesnippets Tag: 120777

    - HttpCFG DS Mapping not working I'm trying to configure DS Mapping with httpcfg. I have a test application using HttpListener which is listening on port 8001 ssl.

I know for sure the certificates are fine, and my AD mapping is ok, because if I test with IIS, it works perfect, and authenticates the client with the Windows user. But as soon as I move to my application and httpcfg, it validates the certificates, but it does not authenticate the client with a windows user.

    - XmlSerializer usage 1) I have an XSD that defines a document structure 2) I have a business object whose internal state can be represented by an XML document that is conformant to the XSD specification Many times, the first thought a lot of folks have is, "Silly, just run your XSD through xsd.exe and you can get a dataset or a class model!" That's not going to work for me, though. My business object contains a good bit of logic and the lightweight zero-method classes that are generated by xsd.exe are not appropriate for what I'm doing. So, I decided to take the approach of implementing the IXmlSerializable interface instead. Life is good. I'm curious, though, how folks insulate their business object from changes in the schema? This object's state is being persisted as an XML string. There will come a time when I have to change the XSD to encance the feature set. So, my class will have to be able to Deserialize its state from either of 2 (or more) different XSD Schemas because there may be older persisted versions (and yes, I want to validate the XML). How do people generally handle this scenario? (no...just not validating the XML is not an option) Here's my approach: If the Class is called Person, then The Class Person Implements the IXmlSerializable interface The Person class has a number of private nested classes (so they have access to the Person class's state fields). These are called DeSerializationFactory Version1Deserializer Version2Deserializer Version3Deserializer ... VersionNDeserializer Serializer When ReadXml is called on the Person Class, the NamespaceURI property is checked. Based on the value of that property a Version[1 2 or 3]Deserializer is created via the DeSerializationFactory. The resultant serializer deserializes the state and then life is good. When WriteXml is called, the default Serializer instance is created and the state is written as XML (always the latest version). This seems to be working for me, but I was curious how other folks mitigate this. Tag: .NET Codesnippets Tag: 120742

    - Drawstring inserts spurious linebreak after character #132 I am using DotNet v1.1.4322.

    - Seemingly simple regex question I'm using the following regex expression where "searchword" is a string: string regrexstr = @"( |^)\b" + searchword + @"+( |\b)" My goal is to use this string to ultimately replace all occurances of searchword as long as: a) it has a preceeding space or it's the beginning of a line AND b) it is suffixed with a space or a newline character The problem right now is that using the above string and calling Regex.Replace also replaces the leading/trailing spaces. I want the spaces to count during the match, but be ignored during the replace. Is that easily do-able? I'm probably going about this the wrong way. In short, I want to do a word replacement throughout a large file. TIA! -sb Tag: .NET Codesnippets Tag: 120706

    - PublicKey of System.Xml assembly I need to make some classes in my assembly internal. I am using XMLSerializer to serialize the objects of my classes. XMLSerializer cannot access my internal classes. So I am thinking that adding System.Xml as a friend would make my internal classes visible to XMLSerializer. Adding System.Xml as a friend requires public key of the System.Xml assembly specified. I can get the PublicKeyToken, but not the public key. I tried following code also but no luck, it just returns 16 bytes (0000000040000000). Assembly assembly = Assembly.GetAssembly( typeof(System.Xml.Serialization.XmlSerializer)); byte[] pubkey = assembly.GetName().GetPublicKey(); Any ideas to get the public key of System.Xml assembly, it doesn't have to be programatically. Thanks! Tag: .NET Codesnippets Tag: 120700

    - WSS document event handler that will use System.web.mail sendmail I am not using vs studio 2.0 I have 1.1 I have a WSS document event handler that works on a document insert, I want to use system.web.mail to get to sendmail and put out an email. Document event handlers are written with C# class library which does not allow me to reference system.web.mail. I use use the interface with a web control and reference the web control from within the document event class but when I compile I get c:\Documents and Settings\cmello\My Documents\Visual Studio Projects\SISWorkflow\bin\Debug\SendMailCtrl.dll Referenced class 'SendMailCtrl.DocLibSendMail' has base class or interface 'System.Web.UI.WebControls.WebControl' defined in an assembly that is not referenced. You must add a reference to assembly 'System.Web'. I am thinking that is because in the SendMailCtrl dll there is a method that uses SendMail and the reference to System.web.mail inside the web control project is the reason that I cannot create a new instance of the web control object in my C# document event library and call the method to send mail. Help!! please I need to have a document library insert event send my custom email to users who have alerts set without having to go into CAML and rewrite the alert notification AARGH -- cindy Tag: .NET Codesnippets Tag: 120695

    - StatusStrip layout Greetings, We are using StatusStrip to present various status messages, progress bars, and so forth, throughout the user experience. We are finding, however, that the layout leaves something to be desired, or we do not have a good understanding of how layout is managed. In particular, how does one designate specified regions for one text or another or a progress bar? For example, without things hiding and moving around? Is there a way to do this, something like what taskbar does for us, or what one might find in Microsoft Word or Excel? Thanks in advance. Best regards, Michael Tag: .NET Codesnippets Tag: 120691

    - Setting StringBuilder.Length not behaving per documentation Perhaps this has been discussed elsewhere - if so, I couldn't find it. The StringBuilder.Length property is explicitly documented as padding the length with spaces if .Length is set to a value greater than the current length. I'm hoping to get this behavior. However, when I set .Length to something greater than the current length, the padding is done with null characters ('\0'), not spaces. Is this the actual intended behavior (and the docs are wrong) or a bug (and the docs are right)? Any help in this would be appreciated. Thanks, Donnie Tag: .NET Codesnippets Tag: 120686

    - Serialization Files Compatibility I pciked up a project and am encountering several deficiencies on the architecture. My current concerns are the persisted data files that are written and read through dynamic reflection and Serialization/De-Serialization. The application has been going on for a while and is using .Net Framework 1.1. They intend to switch to .Net Framework 2.0. If data files are saved through an application saved on .Net 1.1 and later attempted to read through an application running on the .Net 2.0 Framework, will it work? Also, this is a number crunching application. There will be versions running on 32-bit machines and 64-bit machines. Can Serialized data files be shared between versions of the application running on the 2 platforms? -- Ed Reyes Tag: .NET Codesnippets Tag: 120685

    - ClickOnce - Setting up a staging and production versions I want to be able to install a staging version and production version on my desktop of a ClickOnce application. I have created two separate virtual directories on a web server. I changed the product name in the Publish - Options dialog. When I install from the staging location, it overwrites my production version that was installed from the production virtual directory. Is there a product guid that is maintained? Any way to accomplish this? Tag: .NET Codesnippets Tag: 120680

    - creating a compile time error... is it possible? Hi, I'd like to create a compile time error in my class... maybe there's a way already built in in the framework so I can achieve what I want... I have 2 constructors in my class. One of them has mandatory parameters, I mean, they should not be null nor empty (for strings). So I'd make the validation in the constructor and generate a compile-time error if the validation does not match... Is there a way to achieve this or to specify mandatory parameters? (I'm using C#) thanks ThunderMusic Tag: .NET Codesnippets Tag: 120677

    - Querying Active Directory Hi Can anyone tell me, how can I search for Domain Administrators on a network. What I mean is by using DirectorySearcher I can search for normal users, which goes something like DirectorySearcher ds = new DirectorySearcher(new DirectoryEntry()); ds.Filter="objectCategory=User"; ds.FindAll(); Similarly how can I search for administrative accounts?

    - ActiveX controls not painted on a TabControl of a UserControl Hello, I'm trying to build an application using some ActiveX controls (Microsoft Web Browser and Windows Media Player). I first put a tab control on a form, with activex controls on tab pages. Everything went ok on the different tab pages. I came to a problem when i placed the tab control on a user control instead of placing it directly to the form, With the user control on the form, only the activex controls on the first tab page would display, activex controls on other tab pages are just not painted. Does someone know where the problem comes from ? Thanks for your help, Valerie Tag: .NET Codesnippets Tag: 120664

    - startup times woes... Hi All! I try to understand and improve my application cold start. I already load as little as possible in the Main(). Now I have a test which gives strange results, and I try to understand what it means. test 1: ==== I reboot, launch a small .NET executable, which takes 7 seconds, and launch my application, which takes 30 seconds. test 2: ==== I reboot, launch my application, which takes 70 seconds. Now this doesn't add-up, why? Any idea what's going on? I'm thinking to write a small "QuickStart" application which "initialize" everything. How should it work? Tag: .NET Codesnippets Tag: 120659
