• Visual C# What's the syntax around INotifyPropertyChanged ?

  Hi, simple question regarding the syntax around interfaces. I have a bound business object, and it implements some interfaces, most notably, IEditableObject and INotifyPropertyChanged . I have these working just fine but, thing is, coming from a VB background, I'm not really sure I understand the C# syntax. Take IEditableObject for example. I have this... public class DataObjectBase : IDataErrorInfo , IEditableObject , INotifyPropertyChanged { void IEditableObject .BeginEdit() { snip } void IEditableObject .CancelEdit() { snip } void IEditableObject .EndEdit() { snip } Now, I take this to be the methods I need to implement, to satisfy the interface implementation. So far, so good, direct similarities to t ...Show All

• Windows Forms !!!HELP!!! Is ClickOnce useless? Publishing a Clickonce application after certificate renewal.

  I recently renewed my certificate through thawte and found out after signing our clickonce application that clickonce does not play well with the renewed certificate. The problem seems to be that during the process of renewal, thawte and apparently others require a new private key to be generated for the renewed certificate. So it seems there is a critical flaw in the ClickOnce architecture if it requires your code to be signed but can't handle the industry standard of renewed certificates. The only other option is to be your own certification authority but that requires distributing your CA certificate before clients install your application. If we have to have our clients uninstall our software and reinstall it because of this, then ...Show All

• SQL Server Problems with neural net viewer, lift chart and predictions still ocurring in SP2

  Greetings, I have a mining structure that I am using to perform a text-mining classification task. The mining structure contains three models: a decision tree, a naive bayes and a neural network. Both the decision tree and the naive bayes models process without any problems, but I am having significant difficulties with the neural network model. Initially when I processed the model, processing would fail altogether with the following error message: "Memory error: Allocation failure : Not enough storage is available to process this command" This was remedied by taking the steps prescribed in http://support.microsoft.com/kb/917885 (I upgraded to SQL 2005 SP1 and applied all available hotfixes listed in http://s ...Show All

• .NET Development CodeDom Generated code Debugging

  I have done a lot of searching for this over the past month or so but haven't found what I see as an answer. I am working with a program that will allow a user to create and compile a CodeDom Graph from a C# form. What I need to do is create a way of letting the user debug the program they have created. Either in our Form or in .NET. The best way I could think of debugging it in .NET is to create a project file with all of the info and generated source file. I didn't really like this idea so if you have a better one... I have read quite a bit about SOS and MDbg and don't quite know if I could use these either. If anybody could point me in the right direction i would be much obliged. I'd recommend that you add a call to Debugger.Brea ...Show All

• Visual Basic Creating a program that restarts a server

  I wouldn't be asking this if it weren't for someone that has exploited a bug in our Server and has been using it to run two instances thus shutting it down, now I would like to make a (FREE!) program that restarts the server if it should hang, shut down, or lock up giving a run time error. I have looked through an infinite amount of forums, thumbed through my books and I can't seem to find anything of help. We could use this ASAP and if anyone is willing to help it would be much appreciated. I was thinking something simple, but I can't quite figure it out, something like: if system.diagnostics.process. (C:\______) then system.diagnostics.process.start(C:\_____) end if I would like to thank everyone in advance Well th ...Show All

  Hello I am having a problem accessing the ODBC tables from the Visual Studio .NET 2005 version I am trying to use the Server explorer (View a Server Explorer) option in VS 2005 to acce ss the data through one of our properiatiary database.

• Software Development for Windows Vista Game Maker not running...

  I have been using a program called Game Maker on XP for almost three years and I would hoped that it would have worked on Vista. Unfoutunately, it didn't work on Beta 2, and now it doesn't run on RC1. This leaves me a little scared because it is a program that I have to use. For reasons that are unexplainable without a long story, I am solely running Vista on my machine. To make a long story short, XP home's repair doesn't work at all and I can't reformat at loss of all of my files. I installed vista on a partition that didn't have anything important on it. But, I figured that even if I wanted to go back to XP, vista could use some testing. Here is what happens when I open Game Maker 6.1. You can download it and test for yourself at http:/ ...Show All

• SQL Server selectively receiving

  I have a scenario whereby I will have 200+ clients putting messages onto a service broker queue. This message will go through a pipes and filters based messaging system, and ultimately the message will pop out the other end. Here's the question: what is a good way of making sure the same client gets the response to the message he received. Is there anyway I can selectively receive messages from a queue, i.e., pass a correlation id in with the message, and then filter messages based on that id. Or if someone knows a better way to do it altogether i'd really appreciate it. Many thanks, Paul How about if every client had its own queue. My message could have a Return Address, giving the name of th ...Show All

• SQL Server Is lineage more trouble than it's worth?

  Very often during dev. I add processes that don't change the metadata of a data item (for example a new sort) yet the linieage id is changed.  This causes lots of headaches down the pipe.  If metadata of a data item is not changed in the pipe, why is the lineage id changed If lineage is not smart enough to figure out when some metadata was actually changed, should it be made smart enough   Or optional Ken kenambrose wrote: <<the column in the output is not the same column as in the input>> I guess it depends on your definition of "the same". If a column has exactly the same name and type, to me it is "the same". The fact that behind the scenes, way down in the bow ...Show All

• Visual Basic Saved variables--lots of them.

  Hello, I'm trying to make a program that works as a sort of daily planner. It's going to be very simple, but works on the fact that I will have "slots" for activities at half-hour intervals. When I have finished with that particular slot, a messagebox will appear and a noise will play. This is a personal project and I want to use it to help me not over-work (a strange thing I know, but I almost never look at the time ^_^) The whole thing will have differing amounts of "working" school loads (sport doesn't count as a studyable subject). To make matters worse, I want to add that I need some sort of way of storing notes, but I'll save that for a later date. Right now, I'm desperate to know how to dynamically save variable ...Show All
