    - what is Impersonation Hi, I will give you a short example. When a web site runs under the IIS, a process lunches. Usually it is the w3wp.exe or aspnet.exe. That process runs with a set of permissions. When you are trying to connect to a web site using the brower, all requests get executed by that process and its permissions. The process has some rights to perform access to the file system or to any other resources. Now lets say you are using reporting services in your web site. In the reporting services you give user GUY KOLBIS permissions to execute reports. If you will try to run reports from a web site using the process, you will get an access denied. So, what you need to do is to impersonate to a user that has permissions to execute reports. In our case it is GUY KOLBIS user. I hope this helps a bit.

    - Pinvoke question: marshalling pointers to blittable types I think that in the case you cite, it is certainly correct, e.g. passing structs from C#, by ref, is the same as passing a pointer to that struct in C/C++, same goes for bool too. I cannot say however, if the actual address of the managed bool, is passed in or if some copying takes place first, so this may not quite be as it seems, but to my knowledge it is the correct way.

    - ReferencedAssemblies of CompilerParameters What assembly does System.Net reside in How about System.Management See the problem Namespaces do not map to assemblies directly. Therefore, short of creating a lookup table that maps namespaces to assemblies, you can not infer assembly names from namespace names. However adding references to assemblies is harmless as they won't actually be loaded or used unless their needed. Therefore the general approach is to include many (if not all) the standard system assemblies and then allow users to specify additional references to include. For example this is how you tell VS (which uses the same compiler under the hood) what additional assemblies you need beyond the standard ones.

    - Hook Callbacks on a new thread Yes, that's a horrible hack. That basically guarentees to slow everything down. I would start a background GUI thread. It will remain running without eating the CPU. You can do this without having another Form with the ApplicationContext class. For example: Code Snippet /// /// ApplicationContext-based class to be able to create a second message pump /// Parts lifted from Stephen Toub and http://blogs.msdn.com/toub/archive/2006/05/03/589423.aspx /// internal class ProgramApplicationContext : ApplicationContext { private delegate IntPtr LowLevelKeyboardProc ( int nCode, IntPtr wParam, IntPtr lParam); private const int WH_KEYBOARD_LL = 13; private IntPtr hookID; public ProgramApplicationContext() { Form activeForm = System.Windows.Forms. Form .ActiveForm; // make sure we're informed of the main forms closure System.Windows.Forms. Form .ActiveForm.FormClosed += new FormClosedEventHandler (ActiveForm_FormClosed); using ( Process curProcess = Process .GetCurrentProcess()) using ( ProcessModule curModule = curProcess.MainModule) { hookID = SetWindowsHookEx(WH_KEYBOARD_LL, HookCallback, GetModuleHandle(curModule.ModuleName), 0); } } protected override void Dispose( bool disposing) { base .Dispose(disposing); UnhookWindowsHookEx(hookID); } ~ProgramApplicationContext() { Dispose( false ); } internal static void StartMonitoringKeystrokes() { // create another thread to service another message pump Thread thread = new Thread ( new ThreadStart (ThreadEntry)); thread.IsBackground = false ; thread.Start(); } private static void ThreadEntry() { ProgramApplicationContext ap = new ProgramApplicationContext (); Application .Run(ap); } private void ActiveForm_FormClosed( object sender, FormClosedEventArgs e) { this .ExitThread(); } private IntPtr HookCallback( int nCode, IntPtr wParam, IntPtr lParam) { Trace .WriteLine(nCode); return CallNextHookEx(hookID, nCode, wParam, lParam); } [ DllImport ( "user32.dll" , CharSet = CharSet .Auto, SetLastError = true )] private static extern IntPtr SetWindowsHookEx( int idHook, LowLevelKeyboardProc lpfn, IntPtr hMod, uint dwThreadId); [ DllImport ( "user32.dll" , CharSet = CharSet .Auto, SetLastError = true )] [ return : MarshalAs ( UnmanagedType .Bool)] private static extern bool UnhookWindowsHookEx( IntPtr hhk); [ DllImport ( "user32.dll" , CharSet = CharSet .Auto, SetLastError = true )] private static extern IntPtr CallNextHookEx( IntPtr hhk, int nCode, IntPtr wParam, IntPtr lParam); [ DllImport ( "kernel32.dll" , CharSet = CharSet .Auto, SetLastError = true )] private static extern IntPtr GetModuleHandle( string lpModuleName); } Since this class needs to know when the main form is closed, this needs to be run after the main form has been shown. This can be done by handling the Shown event on that form, for example: Code Snippet private void Form1_Shown( object sender, EventArgs e) { ProgramApplicationContext .StartMonitoringKeystrokes(); } Tag: Visual C# General Works in Debug but not Release.

    - How can I add fields to the assembly version?? The first thing you need to do is make your new attribute class. Code Block [ AttributeUsage ( AttributeTargets .Assembly)] public class AssemblyUrlAttribute : Attribute { private string _url; public string Url { get { return _url; } set { _url = value ; } } public AssemblyUrlAttribute( String url) { _url = url; } } Then, add the namespace your class resides in to the using clause of AssemblyInfo.cs. Now you can declare your new attribute inside of AssemblyInfo.cs. Code Block [assembly: AssemblyUrl ( "www.kodefuguru.com" )] Now, you can do the same with AssemblyMandatory. Remember that if you name it AssemblyMandatoryAttribute, you can declare it as [assembly: AssemblyMandatory()]. The key to this is that you have derived from Attribute, and you add the attribute [ AttributeUsage ( AttributeTargets .Assembly)] to the class. Tag: Visual C# General Works in Debug but not Release.

    - C#.NET 2005 Windows Service Crashing automatically Hi Rahul, I don't have a straight answer to your problem, but usually when a .NET program crashes straight on, not throwing exceptions that "you" can catch, it is usually something outside the Framework, or its inner workings, and most of the time, because of us, some code that isn't explicitly releasing objects or using stuff in a wrong way. You seem to be using Interop for the Office thingie... do you: System.Runtime.InteropServices.Marshal.ReleaseComObject(interopObject) after your done using it You can also try to use some kind of "Instrumentation" and make your windows service log its action into a text file or database, that way it might also help you to track down if it always crashes doing some kind of action, and who knows, narrow your scope of the problem. Hope it helps, Fernando Nunes Tag: Visual C# General Works in Debug but not Release. Visual C#

    - Accessing objects in a Form Class from another class or form Setting the control's modifier to public or internal will make the control visible outside of the form. The catch that's probably snagged you is that you can only access instances of those controls from an instance of the form. i.e. // This will work.... MyForm form = new MyForm(); form.textbox1.Text = "Hi There!"; // This won't... MyForm.textbox1.Text = "Whups!"; If you're trying to access something like the single form instance created in: Application.Run(new MyForm()); You might want to pass the instance of the form to the class / methods being called.

    - Problem with Interop DllImport Memory Corruption and AccessViolationException You've almost got it. Remember that in C++ an array is just a pointer so in your case you are marshalling two pointers to C++ but it is expecting buffers. Therefore you need to modify your C# structure definition to define the size of the arrays (MAX_PATH+8 and 1024) respectively. One way to do this is use the MarshalAs attribute and specify the SizeConst option to specify the length: [ StructLayout ( LayoutKind .Sequential, CharSet = CharSet .Ansi)] public class OutPutPoint { [MarshalAs(UnmanagedType.ByValArray, SizeConst=264)] public char [] cDevicePath; [MarshalAs(UnmanagedType.ByValArray, SizeConst=1024)] public char [] cLinkPath; } Michael Taylor - 12/8/06 Tag: Visual C# General Works in Debug but not Release.

    - Getting security warning when starting Visual Studio. Some more info: I figured out where the dialog box comes from, see here: http://msdn2.microsoft.com/en-us/library/ms228217(VS.80).aspx The issue seems to be that in the solutions I'm building to a directory higher in the hierarchy, but still within the directory tree that belongs to the component (Several solutions build into a single binary directory). So the security police seems to be a bit over active. And the funny thing is that when I click to load the project, and ignore the warning in the future, a .suo file gets written. And if I include that .suo file in the installer, then no problem! So there goes the security! Anyways, I still prefer a good solution to this then this hack...

    - interface An interface comes into play when you want to create a contract of operations. A consumer does not care about an object, just that the object that he/she is getting will do the work . For example say you have a database layer and it attaches to the db and extracts values. The business layer process that data and sends it to the user/Gui. What if the database is going to change, say its a financial database and the company providing the info is going out of business. That requires a new vendor and its new database. The user still needs data for reports and the new database will fulfill that. If the business layer is communicating with the database layer with interfaces and not objects, a programmer can write a new database extraction and return the data as per the spec of the interface. The developer can choose to reuse the original classes or write a new one...just as long as the contract is implemented in the interface. The other levels biz/gui don't change! There is the benefit. The interface removes the need to be tied to a specific object or to return a specific object. One sees this in a factory pattern. One layer calls the factory and gets the interface. The factory can return any object as long as it conforms to the interface. The user can still cast it to the original object if it is known...but the interface allows a generic/common way of transferring objects that does not have to rely on all objects deriving from the same base.

    - Generic Multi-Dimensional Arrays Comparison They always say "Divide and Conquer" So to me all a mulidimensional array is a list of lists. (using your example). You probably see where I'm going with this already... One would have to assume that the Z order for each of the lists would be comparable. Example we have a multidimensional list of lists of cars MODEL, MAKE, MANUFACTURER X,Y,Z MODEL, and MAKE are passed in for the same MANUFACTURER for each src and dst list. The MANUFACTURER must be the same for each comparison of a set of src and dst lists passed to your routine above. Iterate through all MANUFACTURERS (Z order) and you've got it. Just a thought.

Hi everyone,

Today I came across this weird problem in a smart client applicatoin project. There is a function which saves information to the database using datasets (not the best solution! but in process of refactoring). Well, the problem is that the function works in debug mode and it saves the info but in release mode one of the values changes therefore wrong information is saved to the database. I've already checked the execution path for processor directives such as #if DEBUG #endif and... nothing's wrong. As far as I know the only thing which may change the application's behaviour in runtime can be processor directives. any idea your help is appreciated.

Thanks

I suggest you debug the release build - switch on the generation debug info (pdbs) in the project properties for the release config. If the process is not running on your dev machine then you can use remote debugging to attach to it over the network.

Hi,

can you give a bit more information about what kind of value changes and some sample code, that may help figure out what your issue is.

Are you using SQL Server Express or some file-based databases If so, be aware that a new copy of database is copied from your source folder to your bin folder when you compile. Depends on how your folder / project is set up, your database may have been overwritten.
