• Visual C# How to keep base class methods private in a derived class

  I am writing an API (C# class library) to distribute to users of my product. I derive this class (derived.cs) from a base class (base.cs) so that it is a wapper for the base class so that the base class is hidden. I have declared the methods in the base class as protected so that my derived class can have access to them. However, when using the the resulting .dll as a reference in another application the name of the base class, plus all of its protected methods are exposed (in the object viewer). I have also tried to declare the base class as protected, but apparently this is not allowed. I would prefer that my customers not be able to see the base class protected methods. How can I hide the name & methods of the base class ...Show All

• Visual C# Get MAC address of client machine using C#

  How to get MAC address of client machine using C# Not looking for remote machine MAC Address. Hi Padam, The following hyperlink possesses a c # code snippet that reveals all details pertaining to your network interfaces on the local machine only along with it's description. Ideally if you have installed a single nic on your machine, you should get only one mac address as an output for this function, since mac addresses are associated only with nics & other hardware devices that communicate on a network. http://msdn2.microsoft.com/en-us/library/system.net.networkinformation.physicaladdress.aspx If you are going to use this code snippet in your program, then you need to put an if -- else condition checking for the length ...Show All

• Audio and Video Development Using IMFMixerBitmap

  I have a DirectShow application that uses the VMR's IVMRMixerBitmap interface to blend a bitmap with a video. Before using it I understand you have to call IVMRFilterConfig's SetNumberOfStreams method to put the VMR into the correct state, and so far it works fine :) So now I'm trying to use Media Foundation and I've found corresponding interfaces such as IEVRFilterConfig and IMFMixerBitmap. Is the operation of these fairly similar ie. do I need to call IEVRFilterConfig's SetNumberOfStreams() before I can use IMFMixerBitmap I've been trying to do this and using IMFGetService's GetService() to try and get the IMFMixerBitmap interface afterwards but without much success - I keep getting a return code of 0xc00d36ba.. Is there anythin ...Show All

• Visual C# Application settings

  Hi, I've got a three tier program. In the data Access layer(DAL) I connect to the database. I use the tabpage settings in the property screen of the DAL. If you do this on the presentation layer(/windows project) then you get an MyAssembly.dll.config in the bin file. But if you do this in the DAL it doesn't create a config file, so yo can't edit it manualy. Can anybody give me a solution Grtz Annihil8 In reference to the references: the configuration data is application wide, so I don't think how the component retrieves the information should be of major concern. However, it also shouldn't be necessary, and it isn't as clean as you would want. When the configuration information is reque ...Show All

• Visual Studio Team System Work Item automated email

  Is there a way to create an automated weekly email of all the open work items for a particular user There isn't anything inbuilt into the product to do it. It is easy to build such a tool though, using our workitemtracking object model. We do have email notification when items are assigned to someone, if email alerts are signed up for that person. This notification happens even when assigned workitem gets modified, so one option would be to programmatically update open workitems assigned to particular user everyweek and subscribe that person for email alerts - if you do not want to write email sending code in your tool. ...Show All

• Windows Forms AxSHDocVw.AxWebBrowser problem with BeforeNavigate event using IE7...

  Hi, We have a VS2003 (framework 1.1) application that uses the above object on a form. We are having issues with the event now NOT firing. We are deploying this onto lap-tops that work just fine except those that have been upgraded to IE7. On the laptops using IE6, we can intercept the event and render our custom HTML files ready for the browser to load, however on the IE7 laptops the event won't fire and we can't intercept it and prepare our HTML. The laptops are simply being upgraded from our standard build by the addition of IE7 (Windows xp pro base operating system) Please, can someone give me a steer as to why this now happens ... Thanks - Paul. ...Show All

• Windows Forms Datagrid column readonly to user but not the program

  I have a datagrid and i have a column which is read only so the user cannot put anything in it. The problem i have is that i use this column as a results column from the data they put in the rest of the table, however when the program calculates the value from the data and tries to put it in this column it won't do it as it is read only. Is there any way of keeping it read only to the user but not to the program Columns is simply a collection -so you should be able to use something like MyDatatable.Columns("P1").readonly = false ...Show All

• SQL Server Problem with Publication Articles being deleted

  I wonder if anyone can advise, I currently have a replication set to 5 offices. Which has been working fine for some 18 months+, then the replication dropped out. When I looked in the publisher it had lost all its articles and would not allow me to add back in. I deleted the publication and recreated it and then after creating a new snapshot starting rolling back out to the various locations, and one of the locations failed and again all the articles where lost. I deleted and rebuilt the database at that office and went through the same routine again, only for it to happen again, the issue being that now errors where produced!!!. So at present I have the publication and all the subscriptions running apart from this one office. Has an ...Show All

• Visual Studio Team System TF14043: An error occurred computing the delta. Not enough storage is available to process this command

  We're attempting to migrate a fairly sizeable SoruceSafe database into a dual-tier TFS server configuration using VSSConverter. After running analyze.exe, VSSConverter Analyze, then half-way through VSSConverter Migrate we start seeing errors in the EventLog. The app-tier server had been running for about 3 weeks, so we've restarted it and are starting a fresh VSSConverter Migrate. Searching for the win32 error "Not enough storage space is available" seems to indicate that it's run out of memory. However this is a Dual Xeon hyper-threaded box with 3.5Gb of memory and plenty of free disk space.
