    - system.arithmeticexception overflow/underrun error Hi, I need help with my .net framework/visual studio.net. I have recently reinstalled windows, and despite this, all my .net framework exe files refuse to run due to an error in system.drawing.dll in the windows generated code. My research tells me that sometime is changing the FPU registers from the default value. Is there a way to fix this error and prevent the exception without adding extra code to my exe files? (the error affects 3rd party developed exe that utilise .net) I have extensively searched my pc for adware/malware, and it doesn't appear to be the cause of my issue. can anyone help me please?

    - code being truncated Hi All, Anybody come across this problem before, and if so, know what the cause is: 50% of the time, when I go to save my .aspx and code-behind pages, even .config files, I get a message saying "Operation cannot be completed" (or "cannot save" in case of the .config file). It brings up the "save" dialog box, and at this point, usually lets me save. Now the issue is that when I re-open to the page, I see that it has been truncated at a randon line. So I loose work from that line on, because it just gone... Does anyone know if this this is network related, since the files reside on a seperate server to vs.net or some other .net thing.

    - Wrong datatype returned - possible bug? I have recently experienced a rather strange occurrence in one of my VB.Net applications. When extracting values from an oracle database (oracle 9.2.0.4.0) some oracle 'NUMBER' variables are returned as decimal as expected but others are being returned as double. This causes the datareader.getDecimal(0) method to fail with an invalid cast exception. The strange thing is that this code works against other databases running different versions of Oracle.

    - Hooking UnhandledException in .NET module invoked in classic ASP I posted this question in microsoft.public.dotnet.framework.interop but got zero replies in 5 days so I'm reposting in the general framework group hoping someone's got some insight: We have a large IIS/SQL classic ASP site that we are converting to .NET by abstracting functionality into .NET components/methods which are also installed/registered as COM objects so they can by invoked by new ASPX pages as well as by our current ASP pages (Set xxx = Server.CreateObject) My question is how do I hook a handler into the UnhandledException chain for my ASP page invoked components via (Set ThisObj = Server.CreateObject("MyLib:MyObj")? The section of my code where I hook the chain is: If System.Web.HttpContext.Current Is Nothing Then 'Instantiated in the classic ASP environment ' ??? What goes here ??? Else 'Instantiated in the ASPX environment Dim HttpApplication As System.Web.HttpApplication = System.Web.HttpContext.Current.ApplicationInstance AddHandler HttpApplication.Error, AddressOf HandleHttpExceptions ' This works fine to catch exceptions in the .NET assembly on ASPX pages End If I've tried the standard console application hooking: Dim CurrentDomain As AppDomain = System.AppDomain.CurrentDomain AddHandler CurrentDomain.UnhandledException, AddressOf HandleUnhandledExceptions but that doesn't seem to work across the interop/COM boundaries. Anybody got any light to shed on where the UnhandledException event chain lives when the .NET assembly is registered as a COM object and invoked by IIS's object structure?

    - Enabling JIT Debugger I have a wierd problem with the 1.1 framework. During some early development I was getting an invalid cast exception that was displaying the JIT debugger dialog, indicting how I could enable the JIT debugger. This is on a system with the full Visual Studio installed, by the way. I created a file named MyApp.exe.config and placed a copy on the Bin\Debug directory, as instructed the file contained the following lines: <configuration> <system.windows.forms jitDebugging="true" /> </configuration> When I ran my program in debug mode, the problem was unchanged (the same dialog appeared) and when I checked, the config file had been deleted.

    - Alternatives to RealProxy This is a multi-part message in MIME format. --------------030705080200040303030101 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit I'm wondering what alternatives, if any, there are to realproxy for intercepting methods on objects. I'm trying to create code which can at run time change what methods do what. So far, the only way I know of doing this is with a RealProxy which parses the IMessage to call a desired function. I'm particularly concerned about performance, and it seems that the TransparentProxy consumes vast amounts of resources, two orders of magnitude, even if my RealProxy does nothing. I made a small trivial performance suite to test different invocation methods and interception techniques. It adds 1 to 40 as many times as it can in 5 seconds. Results are as follows; Direct: 66292785 counts Direct MarshalByRefObj: 54974002 MethodInfo: 4242595 InvokeMethod: 3425953 Fake RealProxy: 581618 RealProxy: 266322 -Fake RealProxy is a InvokeMethod which calls a static test instance & returns a pre-existing ReturnMessage. It does no thinking, just runs on any InvokeMessage. -Real Proxy calls RemotingServices.ExecuteMessage. -I'm not sure if this will actually work, but i've included the sample. Anyways, I'm wondering what alternatives are available. I think IDynamicProperty/IDynamicMessageSink might have some similar capabilities. I dont really understand either of these at all, and havent found good docs either. The other thing I was thinking of was generating wrapper assemblies. Use reflection to parse in the entirity of a user's assembly, and emit a wrapped version, and have the user's app read from the wrapped assembly. I'm not sure how assemblies parallel to DLL's, but it follows the same idea. The immediate problem I see with this is that anything within the assembly wont be accessing the wrapped versions. If one class has an instance of another class, it'll be the unwrapped version. Is there any way around this? This is really my ideal solution.

    - how to allow edit property in PropertyGrid with only Set method Hi! Within my class (say class A) I have read-only property returning reference to object of type B (since I do not want other to assign another reference to this property). I have created a TypeConverter for class B and I want to allow users to edit properties exposed by object B. And with subproperties its works fine, but property within object A is still "grayed", so User cannot write string value in this field. My GetCreateInstanceSupported() returs false, since I do not want to create any new instance (thats why my B b {get;} has only Get method), but I still want to allow users to edit properties of this object. How to accomplish this functionality? Thanks for any help! GRTX, Paul <code> public class A { B _b = new B(); public B b { get {return _b;} // Read Only, but I want users to edit _b properties within PropertyGrid using TypeConverter } } [TypeConverter(BTypeConverter)] public class B { public int SomeProperty {get;set;} } </code> Tag: Error using System.Type as input argument to Web Service Tag: 92830

    - A design pattern for managing the activation and deactivation of menus and buttons etc in an application Hi all, Does anyone know of a design pattern to deal with the issue of making UI controls active and inactive according to the context of what the user is doing? I've been thinking about the best way to handle this but the only way I can really think to do it would likely be very messy - trying to deal with it in event handlers. I can imagine that trying to disable and enable buttons and menu items and toolbars for a whole host of ui elements for a whole host of different application contexts could be very messy. Are there any particular approaches that i should be looking at to manage the problem a bit better? Thanks everyone Simon Tag: Error using System.Type as input argument to Web Service Tag: 92820

    - Critical Bug Report in the JIT Engine of .NET Framework (v1.0/1.1/ This bug is not a common case and you might not have a chance to engage into it. But when you're going to make an plus or minus operation with signed integer, and the result is overflowed, there is a chance to crash into this bug. Please try this in C#: Int32 i = Int32.MaxValue; i += 10; if (i < 0) { i = -i; } Console.WriteLine(i.ToString()); We expect the output to be a positive number. However, we got a negative ones. In fact, the statement "if (i < 0)" failed and the statement "i = -i;" wasn't executed at all! So the i remain negative still. But when you use "Console.WriteLIne(i)" instead of "i.ToString()", the program will just work correctly. So what happen? I found that in the original code, the JIT will translate il "bge.s" to native code "jge". When you use "Console.Writeline(i)" instead of "i.ToString()", the same il will be translated into "jns". Please see the two snapshot if you got confused: http://www.cnblogs.com/images/cnblogs_com/sumtec/TestJit_01.JPG http://www.cnblogs.com/images/cnblogs_com/sumtec/TestJit_02.JPG When overflowed, the instruction "jge" and "jns" will not perform the same logic. When you're adding two integer and get overflowed, and *immediately* followed by a "< 0" comparison (attn, not comparing to an non-const variable), you'll get a chance to see the bug. However, you will not get burned, unless you use the reference of variable "i" in the same function, eg: "i.ToString()" or "AnotherFunction(ref i)". One of my friend said that, not only when you use the reference of variable "i" will cause the failure, but also some other cases. I guess when this function uses ils like "ldloca.s" will cause the problem. There is another similar case: int i = int.Minimum; i -= 10; if (i > 0) ... There's no public KB in MS now. (At least, I can not find it) And here is my suggestion to work around the bug: 1. Becareful about the side effects of unchecked mathematics operations in C#. Especially, when a comparison between the result and a const zero is needed. If you're sure the operation should not result in overflowed, please write codes like this: checked { i += 10; } if (i<0) ... 2. Or, if you need this side effects, for example, you're writing a hashing algorithm, please use the following style instead: i += 10; int b = i; if (b < 0) ... Any questions, please send email to sumtec@gmail.com.

    - .NET Framework 1.1 (Redistributable?) Hi all. I plan on testing out C# soon, and I'd like to first try it without the full retail version, so that means I need to download the SDK, etc. to compile the code. Anyway, I'm a little confused about what I do and don't have at this point. Recently I download Microsoft .NET Framework 1.1 (plus Service Pack 1 and a hotfix to the SP1) from Windows Update. Is this the same thing as the redistributable Framework? Is it the same as the SDK? If I have only what I downloaded from Windows Update, what more do I need to download in order to use C# without C# .NET Standard, or VS .NET? Thanks.

    - Joining Datasets I have to join datasets, what is the quickest way? eg ds1 = [1,2,3,4,5] ds2=[4,5,8,9,20] jds = [4,5]; ie the data common to ds1 and ds2 is inserted into jds.. I know I can loop ds1 and test but this will be slow, and I am wondering if it is better to create a stored procedure which checks, or insert into temp tables and then check with an SQL query, eg a join I am using two datasets as an example but it can be several.

    - Thread never wakes up again if Application does not have focus I have had this issue before and a check around the groups shows a few other people have had this problem too with no real resolution. I have a class that performs actions. These actions are performed multi-threaded via a ThreadStart in the Main Form. The method that performs this is in a while loop that never exits unless the form exits. It will sleep for 30 seconds after it has performed its action and then it will cycle through the loop again. This works fine and dandy but it seems that if the application does not have focus after multiple executions the thread goes to sleep and never wakes up. This randomly happens after about 30-60 minutes of running in the background. I am wondering if anybody else has ever experienced this problem and whether there were any fixes that they had come up with. Tag: Error using System.Type as input argument to Web Service Tag: 92779

    - performance windows services Hi We are using a VB.NET dll to execute a process (load and validate a file). Sending process from a Windows Application, its load rate is 16000 to 18000 regs/min. The same process is sended as a thread from a windows service (also developed in VB.NET) and load rate decreases a lot. File size is a factor that decreases performance. Rate falls to 50% - 20% of inicial medition. Windows services use normal threads (no pooled threads). When each thread finishes work, notifies the results to the service and this writes the trace. The dll process is Load Dataset from disc. Load File Format from SQL 2000 Database to VB 6.0 object. Read each line from file, break line and insert segments in dataset table as the format says. Validate data in dataset. If there are errors, the load fails generating notification and end process. Insert dataset rows in sql server temporary tables. Validate data completion, refussing registers with data not allowed using Stored Procedures. Insert temporary data into final tables (using same sql server). Notificate results process. Service and dll .NET use other dlls made in VB 6.0, however this is not done frequently. Thanks for your help. Tag: Error using System.Type as input argument to Web Service Tag: 92751

I wrote a web service which takes an object of type System.type . I don't get any exceptions when building the application. But at the start page, which is the default page listing all the services,
I get the following error.

The property 'MemberType' on type 'System.Reflection.MemberInfo' cannot be serialized because it is decorated with declarative security permission attributes. Consider using imperative asserts or demands in the property accessors.

Can anyone tell me how to solve this problem?
