• Windows Forms Can't get progress bar to work

  Hello, I'm somewhat new to .NET and very new to Winforms and am trying to use a progress bar in my app to gauge the progress of a SQL 2005 merge replication process. I have a class that keeps the Syncronization code. The syncronization agent has an event handler that in turn calls a method to grab the status and percent completed of the current merge process: subscription.SynchronizationAgent.Status += new AgentCore.StatusEventHandler(SynchronizationAgent_Status); subscription.SynchronizationAgent.Synchronize(); Here is the method it calls: static void SynchronizationAgent_Status(object sender, StatusEventArgs e) { m_percentComplete = e.PercentCompleted; m_statusMessage = e.Message; } ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. SaveStateMode.SaveState performance

  Back when state blocks were brand spanking new, they yeilded poor performance. I haven't really looked at them since. As I understand it, Effect.Begin(SaveStateMode.SaveState) would use state blocks internally. Is it ok to rely on this I would like to set all render state in my .fx file techniques rather than in the code. To do this, I would just use .SaveState on everything. Will this hurt performance Are there other things to worry about with this Thanks, Brandon I found this post: http://blogs.msdn.com/shawnhar/archive/2006/11/13/spritebatch-and-renderstates.aspx Recent and trusted source... saving state can be slow... I think this is a big opertunity for improvement in D3D and Xn ...Show All

• Visual Studio Team System Performance Profiler Documentation Discrepancy

  I've been using the Performance Profiler and I've noticed a discrepancy. The "Functions Taking Longest" section in the Summary view for intrumentation profiling is defined as "the functions that took the most time while INCLUDING all time spent in their sub-functions" (http://msdn.microsoft.com/vstudio/teamsystem/reference/technotes/profiling_windows_apps/vsts_profiler.aspx). In the Function view there is a column called "Elapsed Exclusive Time" which is defined as "the execution time for the code in the method only (EXCLUDES all child function times)" (http://msdn.microsoft.com/msdnmag/issues/04/12/EnterprisePerformance/default.aspx loc=&fig=true#fig6).

• Game Technologies: DirectX, XNA, XACT, etc. DDS : 360, PC

  Will DDS files that are created for PC work with the 360 is there not some subtle difference between the two or is this something that will be patched up via the XNA runtimes on the 360 upon asset loading Well, from my experiments, the nVidia one works fine in my PC apps, even the MS DDS/DXT viewer views the image as it should be, however, I'm convinced the block order is different on the 360. I'm sure (and hope) one of the nice MS guys can shed some light :) ...Show All

• Software Development for Windows Vista UnloadOnIdle Memory Leak???

  In the ASP.NET WF application we've written, we're utilizing the SqlWorfklowPersistenceService, SharedConnectionWorkflowCommitBatchService and a custom ExternalDataExchangeService. Our persistence service is configured as follows: < add type="System.Workflow.Runtime.Hosting.SqlWorkflowPersistenceService, System.Workflow.Runtime, Version=3.0.00000.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" EnableRetries="true" UnloadOnIdle="true" LoadIntervalSeconds="10" /> Our problem is that over the span of a day or so, the application consumes more and more memory until eventually (once it's reached several hundred MB) it causes performance issues on our servers (excessive paging, etc.). As I began to investigate the issue ...Show All

• Visual C++ new operator changing parameter values in release build

  Hi, I hope someone can help me. I've been in the process of trying to sort this bug out in my code for some time now. I think I've isolated the problem but I can't for the life of me work out why this bug is happening. Basically, the program uses a simple template class that is a dynamically allocated array of arrays (each element of which holds an object of the type which the template is instantiated for). The template class has one method which sizes the array accordingly. It takes two parameters - the first is the total number of elements in the array and the second is how much you wish the size of each subarray to be. Now this code compiles fine and under debug build works correctly. However, on release build the array is not al ...Show All
