• Visual Studio 2008 (Pre-release) Odd problem when passing an array using a callback

  Is there any problem is attempting to have a callback method that has an array as argument public interface class ISomeCallback { [OperationContract(IsOneWay = true)] void OnSomeEvent(array<int>^ pNumbers); } I find that this works fine as long as the array is under 550 in length, but if the array is bigger, then the call never completes, it just hangs.

• Visual Basic Referencing the name of a runtime generated UserControl

  Hi there, Well, I've been chasing my tail a bit with this one and I think I've confused myself enough. I'm working in VB 2005 Express. I made a custom UserControl to display and handle data from realtime sensors. Right now, I'm just dealing with one kind, but eventually there will be five or six different types with varying capabilities, but for the moment, I'm getting started with the easy one. The control works just fine if I place it at design time, but I need to be able to generate them programmatically at runtime and update them (and eventually, save the data, scan for changes, then act upon those changes, but "that's anot ...Show All

• Visual Basic Please help me get started

  I work in a Visitor Center that is looking to install a couple of touchscreen kiosks (computers) for the public to use.  Since the estimated cost to develop a separate program for each computer is too high for us to afford my boss suggested I look into basic programming software and see if I could do it.  I have never developed a program or taken anything more than the basic computer class in college.  I talked to Microsoft support and they told me that I should have no problem doing what we want to do with Visual Basic.net 2003 and that I should be able to handle it.  I installed it and looked at the manual that came wit ...Show All

• .NET Development .Net 2.0: How to handle XML data with RAD features the best way?

  I am about to write a small application that will be distributed to a lot of machines. SQL Server 2005 Express or MS Access does not appear to me as attractive options since they both are very large softwarecomponents which will take up a lot of diskspace. I have been focusing on these two components because I would like to use the build-in RAD features in 2005 and thus I need a Data Source. But I have also though of using ADO.NET DataSet/DataTable XML as persistence since my application is by nature for a single user only single user. How do I handle this the best way Should I design the dataset in the dataset designer, load the da ...Show All
