• Game Technologies: DirectX, XNA, XACT, etc. Dramatic memory leak in DrawText

  I've been banging my head against the wall for the last few days trying to track down the source of a rather big memory leak in my Direct3D-application. Turns out the culprit seems to be the DrawText function. Let me explain exactly what happens: I'm using a variable width truetype font (Times New Roman) created through D3DXCreateFont. I'm using this in various parts of my application, but the part where the problems are easiest to notice is in my custom UI textboxes. I use a function called InsertText to add new characters to the printed string, and everything I initialize is cleaned up properly afterwards. The problems only truly beg ...Show All

• Visual C# Sockets

  Hi there. Sorry for posting this in the wrong forum, I apologise but hope someone can guide me in the right direction. I have googled for this endlessly however the examples are poor or they are ok but cannot seem to understand them or simply there is not enough in depth explaination.

I will have a Server app which listens to a connection and acts to whatever it needs to do (read data from that conneciton and so on) Q is, how do I create a socket listener which will keep running until the client says "close connection" or until the application is terminated I have ma ...Show All

• Smart Device Development Services.exe or another method

  Hi there So basically Id like to hear your idears on the best way to crack down my problem. My problem is that I need to create a service that will run allways on a Windows CE device. This program will run at a set interval given in some external data source either via file or registry. This service will then have to do some checks as to connectivity to a remote file share and stuff like that and if all checks succeede it will launch a CF2.0 executable which will then do more stuff on the fileshare e.g. look for pending auto installations and report back to the server how installation went and propubly also ...Show All

• Windows Forms ToolStripComboBox Theming

  I am playing around with making my own ToolStripRenderer in the beta1 and so far it's going quite well. I noticed that when rendering with the built-in Professional style, any ToolStripComboBoxes in my ToolStrips would get a nice blue gradient. If I use a custom colortable with the professional renderer the combobox will still render with the blue gradient  ...Show All

• Visual Studio 2008 (Pre-release) AuthorizationDomain class gone in FebCTP

  Hi, The AuthorizationDomain class appears to have been removed in the FebCTP. The release notes that I saw mentioned that it moved to another assembly/namespace however it does not appear to reside in the new location. There are some indications that it has been replaced. Does anyone know what the story is on this Thanks, Pat Hi Pat, The AuthorizationDomain class has been removed. The behaviour it provided is now split between System.ServiceModel.Description.ServiceAuthorizationBehavior and System.ServiceModel.ServiceAuthorizationManager. You can specify additional authorization polici ...Show All

• Visual Studio Team System Initialize reference type static fields inline

  It says "Initialize all static fields in Jnj.ThirdDimension.Controls.ControlPainter when those fields are declared and remove the explicit static constructor." but the static constructor contains only logic that can't be moved to initializers: public static class ControlPainter { static ControlPainter() { SetPrintType(typeof(TextBox), PrintType.ExternalPaint); SetPrintType(typeof(NumericUpDown), PrintType.ExternalPaint); } static bool useOnPaint = false; ... } Andrew, That's a bad fix in the example you've given.

• SQL Server SqlDeveloper/SqlExpress Conflict.

  Hi, Background: I'm on a Pentium 2.4 with 1024 mb Memory and 160 Gb harddrive, running XPPro with SP2. I started a project in VS2005Beta2 with Sql2005Beta. When the RTM versions came along I ungraded to VS2005Pro, and tried to upgrade the SqlDeveloper. This ran amuck, but I could still access my database, so after three attempts I gave up temporarily. When it looked as if I was actually going to finish my project, I decided to sort out my Sql. Still had the same problems, but found the Cleanup Utility, which did a great job of cleaning up the residual stuff in the registry. I downloaded SqlDeveloper, and ended up with file reference ...Show All
