Does anyone have links and resources to connect to an AS400 from Java? I remember years ago, somebody told me about a connector that simulates KeyStrokes from the keyboard and other "purest" approach that connected directly. On the web I have found a lot of links, but I cannot find a complete product to do this (I am probably not usin...

I'm trying to consume some .NET web services using JAX-WS. I have generated the Java classes using the wsimport tool. However, when I try to use these (proprietary, not public) web services in Java, I notice that most of the methods and properties provided by the vendor in their C# examples are not avaiable in the generated classes (desp...

The legacy database that I'm interfacing with uses a data buffer to pass rows to applications. To handle this in C#, I wrote a class that provides methods for reading and writing different types in the buffer. Each data file uses one data buffer, but the buffer has to be resized for certain operations. To do this, I added an Allocate met...
I'm allocating a block of memory in C# to retrieve information from an unmanaged data buffer: handle = Marshal.AllocHGlobal(33455); The maximum size of the information retrieved is 33,455 bytes, but the size of the information may be smaller than that in some cases. How can I determine how many bytes are actually being used in the al...

In the new application we want to use the same library so we...
I have written a multi thread unmanaged application which uses COM objects in its worker threads. Everything went fine until I started using .NET objects exported as COM to do the work. Playing around with the code and commenting out parts of the .NET object functionality I managed to pin it down to the usage of COM objects from within...

Hi, I would like to create a server using .NET and Java client (Android application). The client will be connected to the server through mobile network so it's impossible to use tcp socket for two-way communication. I would like to develop a logic for client login: The client sends username and password to the server and server repli...

Hi, I'm hosting my WinForms control in Internet Explorer. Additionally I've implemented IExpando interface to be able to emulate unexisted fields and methods in my C# code when javascript code try to access them.

However, if it does not allow the parent fol...
