• Visual Basic Is there a way to check the GAC for a specified or a list of registrations?

  Ive been messing alot with DLLs, and because of that, I am making myself a small tool to register/unregister them from the GAC and from the Registry. The thing is: Is there a way to retrieve if a DLL has been registered or not By checking the GAC. And if possible also the version it was registered with Or will I have to save the info about the DLLs I register in some other file or something Thanks alot anyways!! :) I'm not sure of your exact problem, but the first thing i thought of when I read it was this: http://www.thinktecture.com/Resources/Software/GacUtils/Default.html ...Show All

• Commerce Server Banners offline after 11pm

  Our CS2007 website stops serving all banners after 11pm and restarts it's normal behaviour after midnight. There are no time restrictions on the properties for the banners, only date restrictions. Is this a known issue/bug Thanks guys. -- Jorge Medeira Daily Start Hour and Daily End Hour are set from the boxes beneath the "All Day" checkbox. When you create it with "All Day" checked, both Start Hour and End Hour should be set to zero. The fact that it ends at 23 means exactly that: you won't see anything after 23:00:00 (11:00 PM). Try these steps (I just tried it on my dev commerce box) 1. Disapprove the ad so you can edit it 2. Uncheck 'All Day' ; the values should default to 9am-5pm 3. Save and ...Show All

• SQL Server SQL 2000 : DROP TABLE : Logged fully

  In SQL Server 2000, is DROP TABLE fully logged operation. I have a table with 1 million records. Do I Truncate before dropping to reduce T-log size Would it make significant difference in log size. For large objects SQL does a 2 phase drop - logical and physical. In the logical it just deallocates the pages. The space may not be immediately available. The actual data is deleted at a later stage. Check out BOL for more info regarding this. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. SpriteBatch - how many, and do we need to recreate them?

  Based on the SpaceWar game, I have some questions... I know it was put together quickly - I'm not trying to slag it off, and I want to learn the best way to do things :) 1. In Screen.cs, the constructors of the screen class create a SpriteBatch instance. In the OnCreateDevice() method it then re-creates them. I'm assuming the instances created in the constrructor won't get used, because the device would be created quite fast, so can they (should they) be removed 2. The OnCreateDevice method says "Re-create" in the comment - does this method get fired more than once Is this because the SpriteBatch class needs recreating each time the window is minimized or something 3. SceneItem inherits from List<SceneItem>, yet in ...Show All

• Windows Forms Refreshing a Listbox

  I have a listbox that's bound to a relationship between a table and a dataview. How do I 'refresh' the listbox when a new record is inserted into the tables 'viewed' by the view If the whole application is shut down and restarted, the listbox shows the new data, so I know the database is right. The data is being filled into the program when you start it, you can either create a button that would allow you refresh, or uses a timer that will open your connection, fill the table adapter, then update the form. I am still new to databases, so I hope this helps. ...Show All

• Visual Studio 2008 (Pre-release) Extension Methods / Property conflict when they have the same name

  I have a question regarding how properties of the same name as an extension method are resolved. In the following example, i'd like q3 to compile. I understand the compiler might have issues with the name conflict, but there is a valid extension method, and the compiler is getting hung up because there is also a property. It can resolve it if i explicitly supply the generic type as in q4 - Why can't it be smart enough to do it for q3 List < int > nums = new List < int > { 0,1,2,3,4,5,6,7,8,9 }; int q1 = nums.Count; // works - uses the property on List<T> int q2 = nums.Count(); // fails: 'System.Collections.Generic.List<int>.Count' is a 'property' but is used like a 'method' - doesn' ...Show All

• Visual C# how to call functions in unmanaged C++ dll from C# app

  Hi everyone, I would really appreciate some help if anyone knows the answer. I've been reading online about this topic for the past 2 days, and so far can't find an exact example to help me. I have an unmanaged C++ dll that is comprised of several C++ classes. I need to be able to access some of the functions/procedures in this dll from my C# application. I have tried using the [DllImport("MITT.dll")] public static extern void Start(); method, but this results in an EntryPointNotFoundException due to the name decorating/mangling that occurs on the C++ procedure names. I then used the dumpbin.exe to find the decorated name, and used it in the DllImport EntryPoint attribute, and this worked, but I don't want to use that solution j ...Show All

• Visual Studio Team System Compare workspace version to shelvset version

If I go to Unshelve/Details/ and then right mouse click on the shelved file, I get a compare menu that has a grayed out option to "compare to with workspace version" but I can't find a way to ungray this option as this is exactly what I want to do! Also I have looked in the command line "tf diff" and it says that the /shelvset option cannot be combined with the itemspec option, so I can's see a way to do it that way either. Does anyone know how I can do this Thanks Rob Hi Rob: We wanted to support ...Show All
