• Visual Studio Express Editions How to create a sort of login?

  Hello I want to make a program for certain people and I want it so that they need to enter a code the first time they run the program.

• Software Development for Windows Vista WWF Performance issues

  I am doing some timing measurements to figure out whether we can use WWF for orchastrating code within our project. Here are some of the numbers I am getting and questions associated with them: 1. For a workflow with about 5-6 activities including a parallel activity and several code activities, the time to create the workflow the first time is more than 300 millisecs (328, 359, etc). All subsequent times it takes about 15 millisecs. What i ...Show All

• Software Development for Windows Vista Lost in a while loop!

  Please help me, I'm lost in a while loop! I have a basic workflow I am designing. It is designed to send an email to a person, and then wait for some time before checking a database. If the database has been updated, the while loop ends. Otherwise, it sends the email to a different person. My problem is with the SendEmail activity posted on the workflows site.

• Visual Basic Can reflection do this?

  I wasn't sure if this was the best place to post this question but I figured why not give it a try. What I want to do is write code that can look at the input parameter values that are passed to a method at runtime. I would suspect this is something we can do using reflection but I can't find any way to do it. I know I can look at a specific instance of a class and look at it's property names and values but what about the methods that are being ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Are there any drawbacks to this?

  Hi again! I had this freaky idea earlier today where I decided to render my entire GUI to a texture and render this texture to the screen. This way, I don't have to go through my entire GUI rendering process every frame, which seems to double my framerate in GUI intensive situations. I only update this texture when when the GUI needs updating. I can't shake off this dodgy feeling that this can't be a good way to do things though. Is there ...Show All

• Visual C# Generic Base Static Constructor behavior

  Hi all, I have found some weird behavior with a class that derives from a genericized base class when the base class has static methods, etc. Here is some sample code: public class TemplatedBase <TDerived> { static TemplatedBase() { Console .WriteLine( "TemplatedBase cctor" ); } public static void TemplatedBaseStaticMethod() { Console .WriteLine( " TemplatedBaseStaticMethod " ); } } ...Show All

• Software Development for Windows Vista Activity Property values not available at runtime

  I am currently experimenting with a custom activity. We have a number of business rule objects which implement various, relatively complex data validation rules. The custom activity allows these business rule objects to be assigned to the activity and for parameters to be assigned as part of a workflow that links together a number of these business rule classes into a sequential [potentially brancing] workflow. So I basically have: BRActivity ...Show All
