    - Tool for viewing assembly load exception stack traces I have an assembly that fails to run because of some SecurityException related to my permission settings. I *really* want to figure out why the failure occurs, but when I debug in VS.Net, it happens so early (during loading) that I cannot step into code to look at the stack trace. The only thing I can know is that it's a SecurityException; no watching of the exception object because I never get to my own code. Is there any way to debug this? I can't even get another process to attach a debug session to, so I would even take doing something like java where I go "java myassembly.exe -verbose"...anything with some kind of verbose logging.

    - FillFromCommand calls Hi, I've been trying to subclass System.Data.DataTable and modify class behavior based on rows being added. I want to override BeginLoadData() and EndLoadData() to accomplish my sorted ends, yet I cannot discern whether or not DbDataAdapter and its descendants call these methods on a table when using the Fill() method. I get as far as FillFromCommand() in DbDataAdapter, and am then foiled by a Reflector which can't seem to get it right (stack exceptions?). If someone could be so kind as to let me know if BeginLoadData() and EndLoadData() are called in FillFromCommand(), or at least point me in the direction of finding out myself, I would be most grateful! happily, -rory 8) *** Sent via Developersdex http://www.developersdex.com *** Don't just participate in USENET...get rewarded for it!

    - Assembly Version Issues Hello All, I am developing a "Business Object" Assembly and "Data Object" Assembly (Remoted) , both of which would be called from .NET and from ASP (using COM layer Interop). I deployed all the assemblies into the GAC and it had a specific version when I deployed it. I developed a service that hosts the Remoting Objects and I deployed the dlls in the GAC and things worked fine. I made a few changes to the COM Interop layer, and when I complied it the versions became different, and even after I manually deploy it to the GAC, the Service does not load the Dll from the GAC, even after restarting the service. It always loads the Dll from its Bin Directory. How can I resolve this issue? How do I make all the projects load the assemblies from the GAC? Is there a way I could force this? Thanks in advance... regards, Chris Tag: Using old dll library in .NET Tag: 55430

    - How to properly deploy shareable assemblies to a server I'm looking for a .NET "best practices" opinion on the following. I have a .NET assembly (call it MyApp.dll) that I want to make generally available to other people in my company. I will periodically be coming out with new minor versions (bug fixes) and major versions (new features) of MyApp.dll. Other people in my company will be using MyApp.dll as a library, in that there are some types in MyApp.dll that they will want to reference from their own assemblies that they are building locally on their machines. So, other developers will be creating assemblies that reference MyApp.dll. Now for the questions: Where should MyApp.dll live? How do I account for multiple versions of MyApp.dll existing side-by-side, ready to be accessed from client assemblies? I would like MyApp.dll to be on a company server. But then what (if any) .NET technologies do I need installed on the server? I could simply set up a Windows directory structure on the server to account for different versions of the assembly, and ask people to point their references at that directory structure, but that seems very clunky. I figure there has to be a well-known way of doing this... Tag: Using old dll library in .NET Tag: 55416

    - Problems when performing operations in ASP.NET Hi, I have been having a problem since friday and could not find out what is going on. I have an app built with ASP.NET (C#), that is used from lots of places inside the company. Lately, out users have been complaining about a problem that, when they click on a image to perform some operations, the browser hangs (white spaces, doesn't repaint). One thing they reported is that they have been having those problems after friday, when the updates for the blaster virus were used. More, they report that some stations still work very fine (those that doesn't have the updates). But, in our development environment, we have machines all updated that work very fine with the app. The machine that doesn't work has the following: Windows XP Internet Explorer 6.0.2800.1106.xpsp2.030422-1633, with SP1, Q818529, Q330994 and Q822925. The one that works: Windows XP Internet Explorer 6.0.2800.1106.xpsp1.020828-1920 Can somebody help me with this? What could be done to find out (and solve) this kind of problem?

    - ServiceStartMode I'm trying to find a name space/class that I can use in ASP.NET to access an exiting windows service's startup type setting. I've found the System.ServiceProcess.ServiceInstaller has an enumeration of ServiceStartMode but that is used to install a new service. My service has already been installed and I'm just trying to determine if the start mode has been disabled. I know that you can use System.ServiceProcess.ServiceController to query the service but it doesn't have any property that can be used to access the start mode..

    - COM Interop - HTTP Binary Remoting Hello All, I am in the process of migrating the business layer of a web application into VB.NET and also implementing HTTP Binary Remoting between the Business Object Server and the Web Server (IIS) from where ASP pages call the business objects. I have a very strange problem. The ASP and .NET Business Object layer interact perfectly as expected if the Web Servers (IIS)'s 'Application Protection' - property in the 'Home Directory' tab is set to 'LOW'. If this property is set to 'MEDIUM', I get an error as follows: Error Type: mscorlib (0x80070002) File or assembly name pstkszrq.dll, or one of its dependencies, was not found. /testDotNet.asp, line 18 The Dll name (pstkszrq.dll in here) is different everytime the error pops up...looks like an internal dll that IIS creates. The error occurs when the ASP file tries to create the Object using late binding. I have no idea whats going on in here...no clue whatsoever. If anyone has any clues....it would be of great help.

    - ASCII files I'm trying to load ASCII files that contain characters from the French language in a way that is independant of whatever Locale the machine is configured to use. So If I have machine who's default Locale is "en-US" and I open some french text like this: [C# exaple that has the same behaviour in any .net languages] StreamReader sr = new StreamReader("C:\\someFrenchFile.txt"); string strInput = sr.ReadToEnd(); Suppose the file contains this: "Le Québec en été." the characters that I get in strInput are: "Le Qu?bec en ?t?." If I change the default Locale in the Control Panel and use Encoding.Default in the StreamReader's constructor parameters, I get the right characters in strInput: "Le Québec en été." What I'd like to be able to do is load the french string with the right characters regardless of what's the machine's default Locale.

    - Request for help regarding .NET code access security I wrote a tiny strong-named .NET console exe assembly which writes to a file "c:\foo.txt". I can place the assembly onto a sharepoint, use the configuration MMC snapin to make my own *MACHINE* permission set granting r/w/dir access to "c:\foo.txt", create my own strong-name code group (public key imported from the assembly) and successfully run the assembly (cmd prompt from sharepoint directory). I assume the *MACHINE* "LocalIntranet" zone is what is (correctly) blocking local file access from an assembly deployed on a sharepoint, but apparently whatever permissions the *MACHINE* LocalIntranet zone revokes from me, my new strong-named code group is granting back to me. BUT ? If I then MOVE my permission set and code group from *MACHINE* to *USER* then I get a permission denied on writing the file! I had thought that the *USER* permission set / code group would override and give me access just as they had when they were *MACHINE* entries. What am I doing wrong? I don't want everyone who has physical access to a particular machine to be able to run an assembly that writes to "c:\foo.txt". I know that we could always restrict access to the assembly using "old fashioned" NTFS/share permissions. But isn't there a way (without changing the righteous *MACHINE* LocalIntranet zone permissions) to say "anybody logging on to this machine can try to run the assembly, but only this particular user will be successful" and control all this within the ".NET Framework Configuration" MMC snapin? TIA. P.S. - Is there a flowchart / diagram / document that explains the precedence logic that the .NET runtime goes thru when calculating code access security to determine whether a particular resource may be manipulated or not? There are a number of levels here ? domain v. machine v. user, and then the predefined zoned v. user-added code groups that grant or restrict access? Tag: Using old dll library in .NET Tag: 55254

    - Defining a static method in an interface Is it possible to define a static method in a C# interface? If not, is there a workaround i can use? It's like this. I'm writing this very small graphics library for .NET. Now there's this class, and it contains 2 methods: class DglSurface() { INativeSurface face; ... internal DglSurface(INativeSurface face_) { face = face_; } public DglSurface(string filename) { // this is where i need help } } Now, face is the native implemetation (SDL, DirectX, OpenGL). The INativeSurface interface is as follows: internal interface INativeSurface : IDisposable { DglSurface Load(string filename); void SetAlpha(byte alpha); void Blit(Point dest_point, DglSurface dest); void Blit(Rectangle src_rect, Rectangle dest_rect, DglSurface dest); int Width { get; } int Height { get; } } Now the problem is: i want to construct a surface from a file, with DglSurface.ctor(string filename). But, I can't declare Load to be static in the interface. So I need an instance - and that's impossible because i need the load function to create one! And it's also not possible to declare a constructor in an interface... So how can I arrange the Load method to be called as a static function? Any workarounds maybe? I'm sorry if this message isn't very clear... -- Sijmen Mulder Tag: Using old dll library in .NET Tag: 55232

    - MethodImplOptions.InternalCall gives Security Exception I have a strange C# problem. Is the following a bug? Because it should be possible to run unsafe code. How can I accomplish this? And where can I read more about this, because documentation on this is rare. I have a project where i need to use some internal calls. In this project I have 'Allow unsafe code blocks' set to true. And in my class i have: [MethodImpl(MethodImplOptions.InternalCall)] extern private static IntPtr GetInvalidHandle(); private static readonly IntPtr InvalidHandle = GetInvalidHandle(); At runtime I get a Runtime Error called: An unhandled exception of type 'System.Security.SecurityException' occurred in mydll.dll Additional information: Security error. Can you please clarrify the problem? Regards, Robert Tag: Using old dll library in .NET Tag: 55230

Hello everybody,
I am new to .NET .
I plan to create a www service that uses old dll library written in C++.
If I use CGI to call this library from IIS , that is supposed to be quite
heavy and resource consuming because for every http request a new instance
of that library will be created ( I understand CGI that way).

Is there any way to encapsulate that library in .NET environment (ASP.NET
for example ? ) so all the requests will be served by preferably a single
instance of that library ?

Any help will be very appreciated,
Thank you
Christian

You could just make a COM reference to your library from within the .NET
application.
