• .NET Development Application.DoEvents in .NET 3.0 ?

  Hello, Is there an equivalent of Application.DoEvents in .NET 3.0 If so, what is it Thank you Tom I don't think there's any such thing in WPF. DoEvents was used basically to process the message queue, but since WPF no longer has the thread affinity of Windows Forms, I'd imagine they've done away with the message queue. ...Show All

• SQL Server Interpreting the percentage in decision-tree model

  Hi, I used a decision-tree mining-model to describe and predict fraud. The table contains 1039 records with 775 distinct value of A-number (the calling party). I used 9 columns in the model. SQL Server reports that only 3 columns are significant in predicting the fraud - BPN_is_too_short (called party-number is too short) - Duration_is_zero - Invalid_area_code The key-column in A-number, and the predicted column is Is_Fraud with the range of values are only 0 and 1. There's no record with NULL (missing-value) in the column Is_Fraud. Mining Legend shows in the first split [-] 625 cases of fraud [-] 150 cases of non-fraud [-] 0 cases of missing In addition to that, Mining Legend shows [-] 79.69% of fraud [-] 19.64% of non-fraud [-] 0.67% Mis ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Dispose

  Hello, I've noticed that apart from the top-level "using" statement, the example code never calls Dispose on anything. Is that something we should care about Does it cause unmanaged resource leaks What resources get disposed for us Thanks, Peter Properties should never return arrays. Methods that return arrays should always made a deep copy. I am just doubled checked the design guidelines. The general rule about calling dispose is that you should call dispose only for objects that you own. Additional an object that owns other objects should dispose this objects during it’s own Dispose operation. (XNA made this wrong) If you got an object from a property you should never call Dispose because you get onl ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Windows Forms and DirectX

  To use directx, you send it a winodw in the form of a control. Is there any other form type this will work with I want to have a windows form on one side, with a directx controlled draw space on the other. How would i go about doing this please Thanks, Mike Hi, I've been using a code very similar to this one in my app, but for some obscure reason the rendering seems not to work very well. The scene seems to be badly pixelized, although all antialiasing options are ok and color + lighting also work. While reading another forum I figured out that if you create your device using the other constructor (replacing this .Handle by this ), then the scene is much nicer, but all objects (meshes and lines) b ...Show All

• SQL Server SQL Cluster Connection issues

  We have a cluster that keeps experiencing intermittent connection problems. Everything from replication falling over (and working perfectly when started again) to SSIS packages failing (and working perfectly when restarted again). Errors messages vary but all pretty much have the same in common - no connection. Eg. TCP Provider: The specified network name is no longer available;Connection may not be configured correctly etc. We have another cluster setup in pretty much the same way, with pretty much the same processes, also replicating.This cluster never has issues. The ssis packages are run from a different server connecting to the clusters, and the distributor both clusters use is also on another server. This seems to be, in my ...Show All
