    - MSBuild heirarchy of projects like corext I'd like to use msbuild to build on a heirarchy of projects, based on the directory structure of the sources like CoreXt does. Is there a good way to do this? I'd like to have some folders where external libraries are located, and some folders where some libraries are built. Further, I'd like to have other projects which depend on some of these libraries, and also depend on each other. I'd like to organize these projects in seperate folders, but I dont' want to have a master "Solution" file which knows about all of these. I would like to have each project as an independent entity and allow the build to be started from anywhere in this heirarchy. For example, a root directory would contain several subdirectories, each of which would contain several projects, or even more subdirectories with more projects. I like the notion of the corext dirs file which allows independently adding/removing projects from the "build" by just editing the dirs file in the projects parent directory. Is there a good way of doing this with msbuild? If msbuild does not support this sort of thing, will it in the future? -- Jaan Tag: How to track Form.WindowState changes? Tag: 119744

    - Possible VS2003 c# compiler bug: error CS0584: Internal Compiler Error: stage 'COMPILE' symbol '' Hi everybody! It's the second time it happens to me... Working with typed DataSets and doing copy & paste, I compile and get weirds messages like these: An internal error has occurred in the compiler. To work around this problem, try simplifying or changing the program near the locations listed below. Locations at the top of the list are closer to the point at which the internal error occurred. error CS0584: Internal Compiler Error: stage 'BIND' symbol 'WindowsApplication1.Form1.Form1_Load(object, System.EventArgs)' error CS0584: Internal Compiler Error: stage 'COMPILE' symbol 'WindowsApplication1.Form1' error CS0584: Internal Compiler Error: stage 'COMPILE' symbol 'WindowsApplication1' error CS0584: Internal Compiler Error: stage 'COMPILE' symbol '' error CS0586: Internal Compiler Error: stage 'COMPILE' Once you get one of these you must exit VS2003, because the compiler does not work anymore... Here is how to reproduce it: Create a Solution, with 2 projects, one client app and one class library. In the class library proyect add a typed Dataset, and a class with a method like this: public MyDataset FakeFunction (MyDataset.ClassificationDataTable table) { return new MyDataset(); } In the client app, call the method in this way (here's where the error is): MyDataset ds2 = MyClass.FakeFunction(ds.ClassificationDataTable); That is you miss it doing copy-paste, you should have written: MyDataset ds2 = MyClass.FakeFunction(ds.Classification); And you got the evil messages, very descriptive, aren't they? The curious thing about it is that if you place the class with the method and the Dataset in the client app proyect, the error message is accourate, so the error only happens when referencing another project: error CS0572: 'ClassificationDataTable': cannot reference a type through an expression; try 'ClassLibrary1.MyDataset.ClassificationDataTable' instead Tag: How to track Form.WindowState changes?

    - Check result of call into Windows API Using Windows XP with all updates applied and Visual Studio 2.0. I am trying to develop some common error-handling of Windows API invocations that fail and am using MessageBeep as the API to test with. Given 1) the following Imports statement: Imports System.Runtime.InteropServices 2) the following declaration of MessageBeep: <DllImport("user32.dll", _ EntryPoint:="MessageBeep", _ SetLastError:=True, _ CallingConvention:=CallingConvention.StdCall)> _ Public Function MessageBeep(ByVal wType As Int32) As Boolean End Function 3) the following code to test passing an invalid value to MessageBeep Dim MBResult As Boolean Dim MBErrorCode As Integer MBResult = MessageBeep(-2) If MBResult Then MBErrorCode = Marshal.GetLastWin32Error End If When I set a break-point after the assignment to MBErrorCode, I see that it has a value of 127 -- "The specified procedure could not be found". I was expecting a value of 87 -- "The parameter is incorrect". Note that when I pass MessageBeep a value of 0 -- a presumably valid value -- I get the same result. -- // Lee Silver // Information Concepts Inc. // // Converting data into information since 1981 Tag: How to track Form.WindowState changes?

    - Single or multiple assemblies for big apps and code reuse? Hi everyone, I have a question about .NET code sharing and reuse, and also about application design best practices / guidelines. Currently, we have many different .NET projects in source depot. Although they are different, in some of them we share C# code by referencing source files that are external (not part of the projects) on each project. For instance, some of our projects have the typical â??sourcesâ?? file with: SOURCES = \ ..\..\some_other_different_unrelated_project_A\fileA1.cs \ ..\..\some_other_different_unrelated_project_B\fileB1.cs \ ..\..\some_other_different_unrelated_project_B\fileB2.cs \ Program.cs Class.cs And so on. Some people in my team think that DLLs and assemblies are evil and should be completely avoided. Therefore, they advocate treating all projects in the depot as one huge, monolithic project (even they are not, as they are different projects), sharing code by referencing source files all over the depot. Basically, each application has one and only one assembly containing all the application source code plus all source code that belong to other projects too but is reused by referencing the other project(s) C# source files. Other team members (BTW facing huge opposition) insist in packing the shareable code into one or more assemblies, although for some people, assemblies and DLLs are absolutely forbidden. Can someone please tell me the pros and cons of each approach? Is it right to be completely against packing certain substantial modules or pieces of functionality into separated assembly/assemblies, as opposed to having one and only one single, huge monolithic assembly containing the whole application + other project source files? Those in favor of having shareable code packed into separate assemblies, instead of putting everything (all the source code of the application plus the sources of our libraries, plus the sources of all subsystems, etc.) into one, big monolithic assembly, point to these other URIs: http://msdn.microsoft.com/practices/compcat/default.aspx?pull=/library/en-us/dnbda/html/distapp.asp http://msdn.microsoft.com/practices/compcat/default.aspx?pull=/library/en-us/dnbda/html/apparchch2.asp http://weblogs.asp.net/savanness/archive/2003/07/22/10417.aspx http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconassembliesoverview.asp So, I wonder, are there any guidelines and/or best practices/patterns/anti-patterns in regards to C# source code sharing and reusing among different projects? Any authoritative answers? Is it reassonable to build big, different applications from one huge source tree, having only one and just one assembly per application and nothing more? Or it makes more sense to split the app into multiple assemblies, but keeping the number of assemblies to a minimum? Thanks and regards, Claudio Tag: How to track Form.WindowState changes?

    - window.close problem Hi! On this URL is the example of my problem.... http://www.usa.canon.com/consumer/controller?act=RedirectAct&fcategoryid=313&modelid=9429&URL=http://www.usa.canon.com:80/consumer/controller?act=SecondRedirectAct&nav=second&fileURL=/app/pdf/slr/Rebel_brochure.pdf&type=DNLD As it loads, it starts to process the script and then comes to window.close that shows the dialog box asking user if it should close the browser window. Since I am using IE as control in .net 2.0 and using some extension to it found on codeproject site, I want to handle all browser UI with my dialogs, but unfortunately event that is supposed to be firing doesn't fire. It is WindowClosing event, that even has cancel parameter. My ideas: 1. find out if there is some hidden property inside Internet Explorer registry that would default the dialog box to yes or to no (no success there) 2. find if there is a way to use Navigate() to the url, then use some event that is fired after the document is loaded but before the script runs (no success there either) 3. make local proxy server that would filter out window.close from the script Am I missing something, please advise.

    - Finally, handling resizes and and MDI's scrollbar. Been trying to figure out how to resize forms indside an MDI Form, when the form itself is resized dynamically, to maximize and anchors do not help. The problem was getting the size of the scrollbars, and effecting the resize at the right time. For me, the answer was finding the MDIClient and AddHandlering its Layout event. MDIClient is the client area inside the MDI form, in my case, without a scrollbar, MDIClient.ClientRectangle.Width was 4 less the MDI.Rectangle.Width (must be two pixels for each of the MDI's borders). With a scrollbar it jumped to 20 (likely the scrollbar is 16 pixels wide). Getting the MDIClient (as found in the newsgroups) is done with a ForEach cycling through all controls in the MDI's control collection and finding the one with the type MDIClient. Should probably be index of 0, unless the user makes it an MDI in the code after other controls are added. The second thing was handling those scrollbars. That is done by the MDIClient's layout event, at which time, the scrollbars et al have been taken into account. Since the MDIClient is not there right away, the Handler must be refered to in the code. The declaration of the MDIClient's Layout event is the same as the MDI's Layout event. B.

    - System.Version Hi All, I've searched the documentation and Google for an answer to this but to no avail. It seems that System.Version does not serialize to XML. I checked the documentation and this type is flagged as being Serializable, it has a default parameterless constructor, and I'm pretty sure it can be binarily serialized without a problem. On my example class I have a field as follows: Public MyVersion As System.Version I initialise this to a new System.Version(5,5,5,5) before serializing. After serializing it to an XML file using the XMLSerializer class all I get in my XML doc is "<MyVersion />" - this seems to imply that none of the fields in the System.Version class can be serialized into XML? Can anyone confirm this? Thanks, Alex Clark Tag: How to track Form.WindowState changes? Tag: 119677

    - Async Sockets, pinned objects and .NET 2.0 Hi, I am migrating an application from .NET 1.1 to .NET 2.0. It is a network application that use asynchronous sockets intensively (with more than 300 active connections on average) With .NET 1.1 I had problems because the buffers used in the BeginReceive and BeginSend calls were pinned and prevented the heap to be compacted by the GC. I managed to solve this problem by allocating the buffers at the application start up using a buffer pool. Now, in the same application, compiled with .NET 2.0 the heap is heavily fragmented. I can see with perfmon that the pinned objects counter is about 4 times the number of pending asynchronous calls (it was exactly equal in .Net 1.1), so it seems that .NET 2.0 pins 4 objects for each asynchronous socket call instead of pinning only the buffer. This make senseless the approach of using a buffer pool (I get the same memory footprint in .NET 2.0 using the buffer pool or not using it). And the improvements done in .NET 2.0 in managing pinned objects are not good enough, so the situation became worse. Am I wrong with this conclusion? If not, Is there any workaround for this? or a way I can do that the asynchronous socket calls pins only the sending/receiving buffer? What other objects is .NET 2.0 pinning in the asyn socket calls?

    - Hashtable.Add fails Hi all, I want to assign a new key value to my hash table (okay, I use the Specialized.NameValueCollection, but this collection is based again on the HashTable). When the key already exists, then the value of the key shall be replaced. That's why I use the Add method which also replaces key values instead of Insert which fires exceptions when a key already exist. Now, I've got a very strange exception: ----SNIP---- System.ArgumentException: Das Element wurde bereits hinzugefÃ¼gt.

Then, the Insert method wants to insert the key - but by whatever reason, the insert fails because the key already exist. Somewhere between the execution of the IF in the Add method and the key-insertion in Insert, the key must have been created. So, I can only imaging that another process (very normal for web solutions) might be more fast and inserted the key value in the meanwhile. Is this a bug or is it a feature? Thanks for any advise!

    - Serializing object properties as CDATA using XMLSerializer Hey, Thanks in advanced. Could someone tell me how to serialize an objects property as CDATA. I currently have a properly as follows which creates the XML Element just fine, however, I don't know how to specify that the long description should be wrapped with CDATA. I have seen in multiple places on the web that this is suppose to be included out of the box in .NET 2.0 and I see a work around for .NET 1.1 at http://geekswithblogs.net/cmartin/archive/2005/11/30/61705.aspx. Since I am using .NET 2.0 I would like to use the out of box functionality if it does exist. [XmlElement("long")] public string LongDescription { get { return _long; } set { _long = value; } } Thanks, Tom Tag: How to track Form.WindowState changes? Tag: 119632

    - Help with registering AssemblyResolve event I am writing an application that uses a set of library assembly dlls that are located in a command line passed location. Originally, I tried to solve this problem by creating an AssemblyResolve handler and registering it very early in hte main function. The problem is that the application actually uses some of these assemblies. In particular, one of the classes (named MainWindow) derives from a class in the library. If the runtime attempts to create a MainWindow before the handler is loaded, then I have a problem. Fair enough. However, the way I understand the JIT, I thought it would not attempt to load dependent libraries until the class is used or a static call is made on that class. I made a seperate "Launcher" class that the main funciton and the handler, but I am still failing to resolve the assembly before I even reach my main function. I am reasonably certain that if I wrote an entire launcher assembly then this method would work, but I'm hoping there's a "cleaner" way to fix this problem. Has anyone ever run into this problem?

    - Pointless IL instructions? I've got a simple console app which just assigns 6 to an int and prints out the value. The IL looks like: .method public static void Main() cil managed { .entrypoint .custom instance void [mscorlib]System.STAThreadAttribute::.ctor() = ( 01 00 00 00 ) // Code size 12 (0xc) .maxstack 1 .locals init ([0] int32 x) IL_0000: nop IL_0001: ldc.i4.6 IL_0002: stloc.0 IL_0003: ldloc.0 IL_0004: call void [mscorlib]System.Console::Write(int32) IL_0009: nop IL_000a: nop IL_000b: ret } // end of method Module1::Main What is the point of these: IL_0002: stloc.0 IL_0003: ldloc.0 Why store something in a variable just to put the exact thing right back on the stack where it was? The proper value was on the stack before that anway, right? Couldn't these two lines be taken out? -Ben Tag: How to track Form.WindowState changes? Tag: 119610

    - What account permissions are required for HttpListener.Start()? With least-privilege user account (LUA) HttpListenr.Start() throws an HttpListenerException with ErrorCode == 5 (ERROR_ACCESS_DENIED). This does not occur when the user is a member of the Administrators group. There's no mention of what privileges the current users requires in order to use this method in the documentation for this method. What permissions must be granted to a user account in order to call this method? In a more general sense, where can we find user account access permission requirements for all .NET framework methods? -- http://www.peterRitchie.com/blog/ Microsoft MVP, Visual Developer - Visual C# Tag: How to track Form.WindowState changes?

    - Gui threads (STA) and calling WMI Posting an issue for a colleague: They are having an issue w/ making WMI calls from a gui thread. Gui threads need to be on the STA and there is some speculation that WMI calls need to be on the MTA, how to mix both? ... The application is hanging on exit. When they break into the debugger, the thread on which it is stuck is in a 'WaitOne' call. The call stack is: mscorlib.dll!System.Threading.WaitHandle.WaitOne() + 0x57 bytes system.management.dll!System.Management.MTAHelper.WorkerThread() + 0x25 bytes I searched around a bit on the web, and found this article: http://discuss.develop.com/archives/wa.exe?A2=ind0306b&L=dotnet-clr&T=0&F=&S=&P=3961 It seems to imply that threads that make WMI calls must be MTA. And, Paul thinks that GUI threads must be STA. Many .NET controls are just wrappers on COM controls, which would seem to imply they must be STA. But, what about threads that are both GUI threads and make WMI calls? Or are both GUI threads and make MTA-COM calls? They can't be both MTA and STA... Any thoughts?

    - Registered JIT debugger is not available Hi all, I need to manage some numerous stuffs in an Active Directory running on W2003 server SP1. I decide to write some VB.Net programs, and i installed .Net run-time 1.1 (version 1.1.4322.573) and Snippet Compiler v2.0.7.1 (www.sliver.com). When running the first program, i get this error message : "Registered JIT debugger is not available.

    - Unbox IL instruction question Hi, I'm referring to: http://msdn2.microsoft.com/en-us/library/system.reflection.emit.opcodes.unbox.aspx There's a lot of stuff here that doesn't make sense to me. This page states: A value type has two separate representations within the Common Language Infrastructure (CLI): A 'raw' form used when a value type is embedded within another object. A 'boxed' form, where the data in the value type is wrapped (boxed) into an object so it can exist as an independent entity. The unbox instruction converts the object reference (type O), the boxed representation of a value type, to a value type pointer (a managed pointer, type &), its unboxed form. The supplied value type (valType) is a metadata token indicating the type of value type contained within the boxed object. Unlike Box, which is required to make a copy of a value type for use in the object, unbox is not required to copy the value type from the object. Typically it simply computes the address of the value type that is already present inside of the boxed object. ________________ Now a few things: It mentions an "object reference" and a "value type pointer." What is the difference here? Aren't they both pointers? An object reference is an address where an object lives, correct? A value type pointer is what then? A pointer? A pointer is also an address where something (perhaps an object) lives, right? What to type O and type & refer to? Another question: "unbox is not required to copy the value type from the object. Typically it simply computes the address of the value type that is already present inside of the boxed object." It seems then that unbox which is supposed to return a value type is simply returning a pointer to what is inside the box. I thought value types were very simple: they contain only the actual data you're using. If you push the integer 6 on the stack, you don't deal with addresses at all, you simply put a 6 on the stack. right? so why is this unbox instruction able to avoid copying from the box and just return a pointer to what's in the box? Isn't that the exact same situation we were in when it was a boxed object? Thanks... -Ben Tag: How to track Form.WindowState changes? Tag: 119598

    - How do you get around this? Sorry for the stupid question, but I've been there and done that. Just that just now I have forgotten it for the moment. It happens when you're in a totally different rut of thought. Bail me out here. Just to quote an example: static void Main(string[] args) { Console.WriteLine((new Class1()).SomeMethod((Object)19)); } public int SomeMethod(System.Object obj) { if (obj == null) throw new System.Exception("The argument is null."); if ((int)obj >= 10) return (int)obj; } Error: Class1.cs(13): 'Exception.Class1.SomeMethod(object)': not all code paths return a value How do you get out of this?

    - Identifying UserName and password used Hi All, I'm hosting WSE 3.0 SoapService based web service, which uses Basic authentication. Since, it's implemented from SoapService, a receiver function receives the soapenvelope. Client posts the soapenvelope using HTTP POST method. How can I get the username and password used by the client? What will happen if my web service is set to anonymous access enabled and a user credential is passed along with the HTTP POST method?

Apparently there are no event associated with a change of the form's
WindowState property.
