• Visual Studio Express Editions Graphics questions in VB

  Hi there, I'm planning to make a graphics program in Visual Basic. Although I used Visual Basic a long time ago, and have somewhat of a knowledge of programming, I am by no means expert (you might say barely past beginner) and have been more of an enthusiast in the past (my real job is design and animation). Recently, I downloaded VB Express and decided to take the plunge again. Before I start cramming all the information that is out there into this tiny brain of mine, I basically have a few questions before I start re-inventing the wheel: 1. Is there a way (some kind of API or code snippet) that can make curved splines in one's pro ...Show All

• Visual Studio 2008 (Pre-release) Custom UIElementCollection and data binding

  I have created a custom Panel. I have also created a custom UIElementCollection for it because I need to do some extra operations when the collection is modified. Everything works fine when the custom panel is used in standalone mode. The problem is when I use this custom Panel as a items host for a data binded ItemsControl, it seems that the items are not added through the overriden Add method of the custom UIElementCollection so those extra operations are not executed. Sadly, the current design of UIElementCollection is very decieving. It shouldn't be virtual because the methods your can override or never called. ...Show All

• Visual Basic using code written in C#

  Hi. I'm trying to use a code library written in C# in visual basic, but i cant figure out how to do it. Here's the library: i want to be able to use the functions in it in VB.

You need to define 'doesn't work'. Can you import it Can you call it Do yo ...Show All

• SQL Server HTTP access to Analysis Services 2005 ?

  Hi, Is there anything in store to allow Excel users not logged in a Windows domain to access 2005 cubes In SQL 2000 you can use an unsupported ASP script (provided by Microsoft) to allow these people to use cubes though HTTP transport. They do have a Windows account however they start their laptop in local mode, therefore normal access with a server name string is not an option for them. They have to use an http connection string. Thanks Philippe Yes indeed, I would really like this feature too. Sorry to post with no extra useful information but maybe some extra activity on this thread wil ...Show All

• Software Development for Windows Vista Interrupt State execution in State Machine workflow

  Is there a way for an EventDriven or StateInitialization activity to be interrupted by another event, say, another EventDriven activity in the same state I've got a StateMachine workflow where each state performs some processing, either in a StateInitialization or an EventDriven activity. This processing can take some time and there is a requirement that the user should be able to cancel this processing and jump to another state at any time.

The cancellation event is pick ...Show All

• Visual Studio Problems opening an MSBuild Project file in VS Beta 2

  Hello I am finding that the beta 2 is unable to open an existing msbuild project file in the editor.  Previously it would just open and be recognised as a form of XML file in the text editor.  Now when I double click on the file in the solution list it draws the tab on the editing pane, with the correct name on it, but does not display the file.  The redraw process for the screen area for the file stops. I can still switch to other files and carry on editing, but when I switch back to this file the display has still not been updated. Is it that VS is trying to be clever and edit the file in some special editor   Is there ...Show All
