    - Custom counters file view is out of memory Hi, For some reason this exception is thrown by our application, when attempting to retrieve a performance counter: ExceptionName: System.InvalidOperationException exceptionMessage: Custom counters file view is out of memory. site: System.Diagnostics.SharedPerformanceCounterInt32 CreateCategory(Int32, System.String, Int32, System.String, Int32, System.String)System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089file:///c:/windows/assembly/gac/system/1.0.5000.0__b77a5c561934e089/system.dll stackTrace: at System.Diagnostics.SharedPerformanceCounter.CreateCategory(Int32 categoryNameHashCode, String categoryName, Int32 counterNameHashCode, String counterName, Int32 instanceNameHashCode, String instanceName) at System.Diagnostics.SharedPerformanceCounter.GetCounter(String categoryName, String counterName, String instanceName) at System.Diagnostics.SharedPerformanceCounter..ctor(String categoryName, String counterName, String instanceName) at System.Diagnostics.PerformanceCounter.Initialize() at System.Diagnostics.PerformanceCounter..ctor(String categoryName, String counterName, String instanceName, Boolean readOnly) at System.Diagnostics.PerformanceCounter..ctor(String categoryName, String counterName, Boolean readOnly) Searching for a solution revealed that others have seen this error but nobody knows whats happening. A fix has been offered: "I did a brief investigation I am wondering if you are using lots of performance counters. I found that there is a .config setting that controls the max fileView memory size. It is <configuration> <system.diagnostics> <performanceCounters filemappingsize="524288" /> </system.diagnostics> </configuration> (see the filemappingsize attribute in the performanceCounters element)" But id much rather fix the problem instead of doing the above in a live environment hoping for the best. In hopes of an answer... Regards Alex Tag: creating new folder Tag: 87402

    - Licensing of controls Greetings I am developing a licensed component. The license is a design-time license. However, I want to do some checks at runtime as well. Therefor, I rely on an embedded license key at runtime. I am using a license file, which I signed with my private key and since the assembly is strongly named, the public key is embedded in this assembly. At design time the license provider is then verifying the file with this public key. Sofar so good, nothing fancy about it (except for the time I spent on this because of the total lack of consistent documentation). However: The next roadblock I stumbling upon is the behavior of LC.exe, or rather VS.2003: When an assembly is built that is using a licensed control, the licensed key is supposed to be embedded in that assembly. This doesn't work with me, at least not most of the time and I don't find the logic behind it. When I create the [assemblyname].exe.licenses resource directly with the License Compiler I can see that the license key is embedded in the resource. The use of LC on its own is already a daunting exercise, because if you follow the scant MSDN documentation, you'll get a LC0003 error (unresolved ....), the only way I got it working is by throwing everything in one folder (lc.exe, licensed control, licenses.licx, ...). When I rebuild the assembly in VS, the LC is called by VS (I learned that in one of the news groups, is this documented somewhere?) and the [assemblyname].exe.licenses resource is re-created, but mostly empty, i.e. without the license key. From my trials with LC.exe, I found out that, when you get an LC0003 error, the resource is still created and then it is identical to the resource created by VS (empty). So it looks like that when LC is called by VS, some error happens, this error is trapped by VS, the whole build process continues and you end up with no embedded license key. The other roadblock I encountered is the behaviour of the GetSavedLicenseKey method of the LicenseContext class. The MSDN documentation states that this method only does what it should do if it is overridden. But it looks like that the truth is much more complex: my experience is that it sometimes does work and sometimes not, and again I don't find the logic in it. In some cases the calling assembly has actually the license key embedded in its resources (easily verifyable with Reflector) and then it happpens from time to time that the saved license key is actually retrieved by this method, without being overridden! The Microsft news groups are full of questions about licensing and most end up with no answer, or in the best case, an adhoc reply from helpful support people. What we need is a comprehensive, consistent documentation on licensing. After all, how can we expect that our customers can use our products in a seamless way if we are struggling ourselves with the basics???? Awaiting your comments (and hopefully some answers to my questions!) Thanks in advance, Roland Tag: creating new folder Tag: 87394

    - Wrapping unmanaged C++ Hello, I have a huge set of unmanaged C++ classes, which I wrapped in managed C++. Everything is in one assembly. Using my wrapper in C# works fine. However, when I would like to use the wrapper in managed C++ I get the following warnings and errors: warning C4945: 'MyType' : cannot import symbol from 'mydll.dll': as 'MyNamespace::MyType' has already been imported from another assembly 'mydll.dll' stdafx.cpp(0) : see declaration of 'MyNamespace::MyType' first seen type is used; re-order imported assemblies to use the current type (Is this caused by forward declarations?) And: error C3635: 'MyUnmanagedNamespace::MyUnmanagedType': undefined native type used in 'MyNamespace::MyType'; imported native types must be defined in the importing source code did you forget to include a header file? My questions: How can I solve these problems WITHOUT having to include my unmanaged header files in the project that uses my assembly? I am not using any unmanaged stuff, so why would I like to include anything? I want to re-use the code at binary level only. Greets, Arthur Tag: creating new folder Tag: 87390

    - Installing VIsual Studio 2002 and Visual Studio 2003 on the same PC Hi, I have Visual Studio.Net 2002 and the .Net Framework 1.0 on my PC. I am considering moving to Visual Studio 2003 and .Net Framework 1.1 for any new projects. Before I begin just wondering if its okay to install both versions on the same PC and if there are any issues I should be aware of. I want to retain the ability to edit/update my old 1.0 projects in Visual Studio 2002 without upgrading them. Basically I want to have both versions of Visual Studio and the Framework on the same box. I'm aware of the notion of side-by-side execution of the .NET Framework but does it extend to the Visual Studio itself. Thanks, Paul Tag: creating new folder Tag: 87388

    - confusing remark in MSDN Control.BeginInvoke() doc I've read a bit about the differences between delegate's BeginInvoke and Control.BeginInvoke, and it sounds like Control's BeginInvoke() ensures that the delegate is invoked in the thread that created the Control's context. This implies no thread pool threads are involved. A test app bore this out. What confuses is me is this note found in http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemwindowsformscontrolclassbegininvoketopic2.asp: Note The BeginInvoke method calls the specified delegate back on a different thread pool thread. You should not block a thread pool thread for any length of time. Why does the Control.BeginInvoke() documentation mention thread pool threads? Are they somehow involved with multi-threaded control programming (I hope not)? Is it just a doc error? Does the "back" in "calls the specified delegate back" refer to some other callback delegate that isn't mentioned? Don't even get me started on the second sentence.

    - Assembly.Gettype freezes On certain assemblies, when I do a LoadFrom to get a reference, and then call GetTypes to get a list of types, the application freezes. If, however, I put a try/catch block around the code, it does NOT freeze, but NO EXCEPTION is thrown. This is for my plugin structure. I have 30 dlls to search. The first 10 are ok. #1, which is not much different than the other 10, fails. Ok.. so I skip that one manually.. 11-16 work, 17 fails. I figured I would inspect the failing ones and see why.

    - Re-flunk-tion! I'm wondering why reflection fails in this instance... I'm trying to do drag and drop using ListViewItem objects. When I check the DragEventArgs to see if it has my ListViewItem, I have to use GetDataPresent to test if it's the data I'm looking for. I have to pass a System.Type object representing the type of a ListViewItem object. But I've found that Type fails to correctly identify a ListViewItem. If I try this: Type f = Type.GetType("System.Windows.Forms.ListViewItem"); f is null. According to MSDN, this should work, as their sample is this: Type myType1 = Type.GetType("System.Int32"); Am I wrong? What's going on? Tag: creating new folder Tag: 87351

    - Monitor (lock) I'm having a tough time understanding the concept of locking "on an object". If a monitor is used to protect a critial section, then what does any object reference have to do with it? Does this allow different instances of the same object to, in fact, run the same critical section and assume they're accessing instance varaibles only? What would be a scenario where some method in class A would lock on an instance of class B? If you're locking to protect global (static) data structures, then you lock on typeof(this), right? Well... what does that mean? You've locked on an instance of the Type class, so no other instance can run that critical section? I guess I just don't understand why you need the object reference. This also leaves me a little confused on the SyncRoot property of may collections. Is locking on 'this' not good enough? Do I actually have to lock on the underlying data structure to assure thread safety. Thanks, Andrew Tag: creating new folder Tag: 87350

    - Reverse usage of public/private RSA encryption keys for licensing? The way that RSACryptoServiceProvider works is that we encrypt with a public key and decrypt with a private key. This architecture works great for people sending messages to me. However, I now have the opposite application: I want to put a license file on a destination computer and be sure that it remains unaltered. It would be great if I could encrypt it with a private key at our office and transmit the public key and the encrypted file to the destination computer, where anybody can decrypt it and read it, but not change it because we have the private key at our office. I've read posts to "simply reverse the public and private RSA keys" but tried several variations of switching RsaParameters.D, DP, P, DQ, Modulus and others, to no avail. I'm sure that a solution exists, just that I do not know it. How do I, in C# .NET, send a license file to a destination computer, with a public key, anybody can read it, but only we can change it?

    - regex puzzle! The objective is to extract the first n characters of text from an HTML block. I wish to preserve all HTML (links, formatting etc.), and at the same time, extend the size of the block to ensure that all closing tags are recovered. For example, simply extracting the first 400 characters of a HTML block may result in an <i> opening tag being including, but its closing tag being excluding. Or a link may get chopped halfway - [... blah blah <a href="ht] may be the last few characters of the recovered phrase. Ideally, if any html opening tag is included in the first n characters, then any number of extra characters should continue to be extracted from the source block until all paired closing tags are found. We can assume that the source block is well-formed HTML, and every opening tag has a closing tag (whether optional or not). Furthermore (if it makes any difference), we can assume that all tags are given in their simplest forms with no attributes (e.g. <p>, <ul>, <li>, <b>), except for anchor tags, which have the href attribute of course. Can anyone suggest a regular expression to do this? Tag: creating new folder Tag: 87268

    - Windows compound files Are windows compound files supported under .NET? Compound files are like a directory - there are several streams in a single file. I have C++ code for some object classes that use compound files and am having difficulty getting it to compile under .NET because some standard windows header files create compiler errors. Even classes that simply use IStream to read and write themselves will not compile, with errors found in files supplied with Visual Studio. Any suggestions or help would be appreciated.

    - Anyone have info on the dreaded Q316146 bug? ... (i.e. There is no Original data to access) I'm absolutely baffled why Microsoft has decided to give so little information about this issue. We here (as with many other's I'm sure) have wasted countless hours of time finding, researching and redesigning around this issue. I wish someone would clarify Microsofts position on this. For example, it would be nice to know a) Yes we are aware of it, it's fixible and is a high priority b) Yes we are aware of it, but it would require a rewrite of ADO.NET so it's taking a long time but a fix is coming c) Yes we are aware of it, but it will not be fixed until .NET 2.0 d) Yes we are aware of it and it's not being fixed. good luck fools! Now let's analyze what this bug really means. Microsoft has banked it's entire future on .NET (which I might add has been a success so far). With that in mind, most medium to large size applications utilize some form of database and DataSets, DataTables, etc... is the new defacto way in .NET to represent this data in memory. This bug is very easy to get as your application get's more complicated. With this line of thinking, shouldn't this be one of Microsoft's highest priororities!!! -Dave Tag: creating new folder Tag: 87265

    - Framework 1.1 Service Pack 1 Question I am addressing this message to Microsoft directly. Recently this service pack was released, and it has fixed many issues. However, one glaring bug fix, for some reason or another, was left out of this service release. The VersionNotFoundException which will occassionally rear its ugly head when using expression columns in datatables. This bug has been known for a while. For some reason, the release of Framework 1.1 didn't fix it, and yet another opportunity to fix it has come and passed. What is the deal? Does Microsoft not know where the cause of this error is? Is it not a priority? I have a large project which uses expression columns on a rather large scale. The only workaround I have ever seen documented is simply "don't use expression columns." For some of us that is just not an option. Does anyone have a workaround? Will someone at Microsoft please look into this and give us developers some advice as to how to work around this bug? Would that same person give us some kind of time frame as to when this will be fixed. I don't care if VS.2005 fixes it. That is years away from being a development solution for some of us. And would that same person please express our frustration to somebody there at Microsoft so this will get fixed ASAP. Thank you. Tag: creating new folder Tag: 87250

    - aspnet_wp.exe Problem I have performance issues with aspnet_wp.exe. Some time I got the following errors on the production server and hang-up the server until I killed the process. Please advice! aspnet_wp.exe (PID: 3648) stopped unexpectedly. aspnet_wp.exe (PID: 4136) was recycled because it was suspected to be in a deadlocked state. It did not send any responses for pending requests in the last 180 seconds. This timeout may be adjusted using the <processModel responseDeadlockInterval> setting in machine.config. aspnet_wp.exe (PID: 1320) was recycled because memory consumption exceeded the 613 MB (60 percent of available RAM). -- DotNet Guerrilla Tag: creating new folder Tag: 87249

    - Dispose Question Just a quick question on implementing the Dispose pattern. The .NET Framework SDK documentation states that an ObjectDisposedException should be thrown from instance methods (other than Dispose) when resources for the object have already been disposed. This would include any non-shared property procedures as well, right? Seems logical. Just looking for verification. Thanks! Tag: creating new folder Tag: 87238

How can I force a new folder to not inherit the security preferences from its

Isn't there a checkbox for that in the security tab?

Since this was the .net framework newsgroup I was talking about
programmatically creating the folder. I found that using Active Directory to
apply rights, you have to create the DACL from new instead of getting the
DACL from the just created folder.
