• .NET Development Passing String Arrays between VB.Net and VB6

  We have a (very) large VB6 application. I'm in the process of extending it and gradualy replacing parts of it with VB.Net modules. I'm writing DLLs in VB.Net and using COM interop to consume them in the VB6 app. This is working great! We are in the business of migrating (very large) COBOL systems and I get a kick out of how VB6 is now a 'legacy' framework in itself. Any way, here's my current problem: how do I pass a string array from the VB.Net DLL to a VB6 consumer. What I want is declaration like so: Public function SomeFunction(Byval StringArray() as String) as boolean I've looked at Default Marshaling for Arrays , but could not make ...Show All

• Visual Studio 2008 (Pre-release) Implementing a SOA entreprise model in WCF without ESB

  Hi Could WCF offer a full framework to build a SOA enterprise model without the necessity of an ESB (like IONA or Bea) I think yes, I don’t like ESB, to use a ESB I don’t need that my services are soap, but now in my big company we are deliberating the necessity of an ESB. Can anyone give me reasons to prevent us of to buy a ESB to model a SOA entrepise model Thanks Javier Hi Javier, We believe, we have all the components to run Enterprise service applications on WCF platform, so if you want to run services between windows to windows, we don't need any ESB.

• Windows Forms Invoke freezes and BeginInvoke queues up too many messages.

  We are using a combination of C# and Managed C++ in .NET 2.0 Our program has a couple of threads. The main thread is controlling the GUI primarily. A second thread runs a very fast running loop that obtains data and controls a piece of hardware (or simulates such). When the second thread gets an update, we have it use Invoke to update the GUI. However, under particularly system intensive conditions, or when the user does something like dragging the window, the second thread will stop when it calls Invoke. We have tried using BeginInvoke as an alternative, but that second thread just runs too fast and too many BeginInvokes get queued and w ...Show All

• .NET Development upgrade to MSDE

  Our company has an existing application (standalone PC app) that uses Access database via the Jet Engine. The program runs on a user’s machine only (distributed from a CD or USB jump drive.). We are looking to convert this application to .NET, keeping in mind that we need to have an easy setup with a royalty free solution.   Should we continue to use the Jet Engine or is it time to upgrade to MSDE Is the Jet Engine being phased out. The new application has to be able to work with the older database. Hi, Read the following for info on MSDE Vs Jet. http://www.teratrax.com/articles/msde_vs_sql_server ...Show All

• Visual Basic Unit testing for beginners?

  I haven't found any beginner articles on how to use unit testing in VB. I'm not even sure exactly what it is (well, I understand the general idea). I'd love for some info or pointers for how to use this technology to help me write more robust code. Can anyone out there help me Keep in mind that I'm not a enterprise developer working on an n-tier scalable system, in a large scale team environment, blah, blah. Just an intermediate level coder that writes his own small scale stuff. Thanks! It's not that I need to. But my code gets bugs creeping in as it gets more complex and gets more difficult to debug as it grows, and from what I unders ...Show All
