• Visual Studio Team System Do I understand VSTestHost and devenv correctly?

  Hi, I have a question about the different processes under process counters in load tests (for example, Process -> Virtual Bytes). Do I understand correctly that devenv process reflects resources used by Visual Studio and that VSTestHost process reflects resources used by the application being tested Thank you.

  I am accessing my webservice through an ajax json call by using the following javascript code: Function DeleteTask(task_key) { TaskWebService.wsDeleteTask(task_key, onComplete, onTimeout, onError); } My question is: how as the developer can I prevent a malicious person from calling the TaskWebService.wsDeleteTask method with any number of task_key values.

• Game Technologies: DirectX, XNA, XACT, etc. Exporting Animations from Maya 7.0

  I have the Maya plugin installed correctly and can export animations which use transformation, scale and rotation on the objects directly but when I animate them using deformers or skeletons I get no animation in either the Maya directx viewer or the standalone directx viewer (once I have exported them). If someone could point me in the direction of some tutorials for the directx plugin I would be most obliged or at least let me know where I can find more information on supported deformers etc and how one should set them up in maya. Realistically all I want to do is create some blendshapes and export them so any pointers on what may be going wrong would be nice. ...Show All

I'm trying to use IndexOf on the table's binding source to get the index number of an entry in the first column but no indexnumber is found... what am I overlooking int indexNo = this .diagnosisListBindingSource.IndexOf( "ARDS " ); ( I know the entry "ARDS " does exist as an entry in the indexed column and the following function gives the correnct number of rows in the table, so I know I'm 'hooked up' correctly....) int count = this .diagnosisListBindingSource.Count; Thank you.

• Windows Forms Catch all Exceptions

  Hi I have a program with several Forms. What I need is to log all exceptions (save them into a database). Is this possible without having to write a "try{ ... } catch(...) {...}" everywhere (and call a static log-method within the catch-body). Kind Regards Well, the best way to be able to catch every exception in your application is by running it in debug mode via Visual Studio. When it runs into a(n) exception, it will display the error, and the type of exception it is. Then you can just implement the code for that particular exception. So if you select a value of -1 and it presents you with an exception, run it in debug mode and find out what exception it is, then implement the catch statemen ...Show All
