• Windows Forms DataRelation, which direction?

  I have two related tables: category and question Each question has a corresponding category_id which is the (primary) key for the category the question belongs to. question->category_id == category->id; If I create a DataRelation between the two tables, does it matter which is the parent table/column and which is the child DataRelation MyRelation = new DataRelation("RelationName", MyDataSet.Tables["question"].Columns["category_id"], MyDataSet.Tables["category"].Columns["id"]); OR DataRelation MyRelation = new DataRelation("RelationName", MyDataSet.Tables["category"].Columns["id"], MyDataSet.Tables["question"].Columns["c ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Overloading WndProc

  Is there a way to overload the WndProc function while using XNA's classes like GameWindow I've seen ways to do it with WindowsForms. Mostly this is for insertion of CD-ROM messages and keyboard input messages. We expose the window handle so I imagine you could do it using that, but we have not tested this scenario so you may get unexpected behavior. Just curious, why do you need to handle keyboard messages this way ...Show All

• Visual Studio 2008 (Pre-release) Feature Request for LINQ designer

  Could I make a small request, or perhaps this has already been done and I'm just not aware of it... When dragging tables into the LINQ Designer I get nice classes that I can customize. But what I would really love is if 2 classes were generated: a base class consisted only of the table's member properties, and an subclass that utilizes all of the LINQ data access features. This way I can decouple the LINQ specific data access code from my business objects and allow me to do other things with them (such as Serialize them!) Can this be done Thank you.. The entity classes generated for LINQ to SQL do not contain any data access logic in them, only some attributes on the properties if you chose to use attribute based mappin ...Show All

• Software Development for Windows Vista c# VFW capVideoStreamCallback(...) (DIB) lpVHdr To Bitmap

  Hi, (Update - previous post stated capSetCallbackOnFrame(..) this was an error sorry for any confusion, the call back being used is capVideoStreamCallback(...)) Im using the old VFW (Video for windows) within a c# application to facilitate video capture, partially throught the excellent ezVidCap control, (activeX wrapper for VFW capture) and due to some unfortunate limitations the win32 API. It is required that the preview runs, whilst recording and that a frame may be captured from the video stream at any time, ie recording, or not recording. ezVidCap will not allow or facilitate frame capture whilst recording but does make available the call back capVideoStreamCallback (). During recording I am using the callback function capSetCal ...Show All

• .NET Development .NET HttpListener has a limit of 2 concurrent requests handled at a time per process, How can I increase it ?

  I created a simple server using HttpListener using .NET 2.0 The server simply accepts http connections from clients, sleep 3 seconds and return "OK" message. Server Code : HttpListener m_Listener = new HttpListener (); public void StartListening() { m_Listener.AuthenticationSchemes = AuthenticationSchemes .Anonymous; m_Listener.Prefixes.Add( "http://*:1234/" ); m_Listener.Start(); AsyncAccept(); } // this method is called in a loop to listen to new clients private void AsyncAccept() { m_Listener.BeginGetContext( new AsyncCallback (OnNewConnection), nul ...Show All

• SQL Server Prediction Query for a "weighted" clustering model

  I have a question about writing a prediction query against a clustering model that has the same column added more than once. Per Jamie, I can accomplish some crude weighting by adding a column to my model multiple times. See this post for an explnation... Now that I have that worked out, I was wondering how my DM query would look If I have Input_A1, Input_A2 , & Input_A3 all being source from the same column in my structure do I have to reference all three when writing my prediction query to be most theoretically accurate, yes, however, I would check to see how the results change for your particular model as you change inputs. If you don't have any missing data, it may not make a significant difference. ...Show All

• SQL Server Black server reports after installing SP2

  After installing SQL Server 2005 SP2 all of our server reports are being rendered with a black background and white text, which needless to say is reversed of how they were being drawn before installing SP2. This only happens when the report viewer is displaying the report in “Print Layout” mode. Normal mode shows the report as expected. Has anyone else had this problem or suggest a solution Thanks in advance. I haven't heard of a resolution that is acceptable yet, with the exception of geting back through all the server reports and deliberatly making the background color white. I'm not too convinced this is nessesarily a video card issue, since every single machine we have seen this on is doing the b ...Show All

• Visual Studio Team System Print Spooler won't start

  Can anyone help solve this problem, all printers have dissappeared from printers and faxesm any attempt to add printer says print spooler not running. I have followed Microsoft suggestions for restarting and get errors 1068 and 1053, nothing seems to work. I am trying to avoid a reformat if at all possible. The problem occured shortly after installing a new printer Lexmark 6200, though not immediately. I was able to use the new printer for 2 days, I then took my laptop to work and used it with other printers at work. At home again used the Lexmark and then next day at work no printers. A problem with the lexmark looping in scanner mode was stopped by removing the usb cord which iam concerned may have caused some sort of corruptio ...Show All

• .NET Development using dispose/finalize..

  I am trying to understand when a class needs to implement dispose. Lets say my class is using an arraylist and some other resources. Arraylist is a managed resource, so in this case should I be implementing finalize If I don't implement finalize my understanding is that the GC would still do a GC on my class and therefore get rid of Arraylist. What about dispose Do I need to implement dispose Let say I have another class using a windows script object. This would be a unmanaged resource. Do i now need dispose/finalize Thanks I don't know how WinForms implements they're Dispose code, so I'm afraid I can't help you there. The purpose of implementing IDisposable (or any interface, for that ...Show All
