• Software Development for Windows Vista InkCanvas - CPU Hungry

  I have a UI with an InkCanvas viewed through a VisualBrush. With only a few strokes on the canvas, CPU utilization approaches 60%. When I set myInkCanvas.Visibility = Visibility.Hidden then CPU utilization drops. I may be able to make a small mockup that will demonstrate the behavior, but I would hope it could be solved without that. This is a snapshot of the stack from the offending thread (which I can't make heads or tails out of): ntoskrnl.exe!KiDispatchInterrupt+0x7f MilCore.dll!MilChannel_CommitChannel+0x12b ntoskrnl.exe!KeInitializeTimer+0x107 ntoskrnl.exe!KeUserModeCallback+0x87 ntoskrnl.exe!KeUserModeCallback+0xbd MilCor ...Show All

• Visual Basic Protecting Class Library DLL's?

  I originally posted this on VBForums.com, but haven't received any replies yet, so I thought I'd try here. Anyway, the project I'm currently working on is getting quite large and we are looking at breaking a few components of the software off into manageable class libraries (i.e. DLL's). I've been experimenting with it over the past few days and the problem I'm finding is that the DDL's are insecure. What I mean by this, is that when we distribute our software to the public, anyone with Visual Studio 2005 will be able to create a VB application, then add our DDL's as references and viola, they now have access to the internal functionality a ...Show All

• SQL Server Select Permission Denied on object

  Hello all, I have just begun to develop a simple web application to maintain phone book / contact details of people. I have been facing problems wrt the connection to the database, while trying to execute the reader it throws this error - Server Error in '/phonebook' Application.

By default users don’t have access to any objects, because their only role membership is "public".

• Visual C++ Windows Services Tutorial / Examples

  Can anyone recommend some good tutorials / examples on creating Windows Services. I would like to use C++ and avoid C#/VB as much as is possible. Additionally, is it possible to control a Windows Service from an external program I have seen some examples of this using the event log to pass commands but never anything that actually works. Thanks Rick Thanks for the articles! They appear to be what I am looking for, however, throughout the authors refer to "NT Services." Are these compatible with the current "Windows Services" in Windows XP EDIT: I am using http://msdn.microsoft.com/library/default ...Show All

• .NET Development Debug initialization code

  How does one debug the initialization code I have a program written in VS C# Express. It works fine on the development machine (Windows 2000 Pro), both inside the IDE and running standalone. I take the same source code and run it under Windows XP and it fails during initialization (I know this because I have a MessageBox to indicate when I return from Initialization). When I run the program in the IDE on the XP machine, it works fine. How do I find out where the initialization code is failing When I call InitializeComponent() as the first method of my C# program. It fails with a message "There has been ...Show All

• Visual Basic VB Selecting the lowest Integer

  Hello again! The program is coming along great... I have a situation where I randomly generated 4 integers between 1-50 What I want to do next is have the program select the lowest and highest numbers from the 4 different dim integers. Can anyone out there lead me in the right direction thanks! Hi, You could write your own implementation of a sorting routine but a neat little thing I found was that you can use the properties of the List class to do your sorting for you like so: Dim ranGen As System.Random = New System.Random() Dim int1 As Integer Dim int2 As Integer Dim in ...Show All
