This is an urgent project that I need completed by end of day Monday at the latest; sooner would be better. I don't have any particular budget at this time, but I don't think this more than a 10-hour project for someone who knows the platform components pretty well. I have a web page running in Pocket Internet Explorer for PocketPC. Within that page, a JavaScript script needs to call a VB.NET DLL running in .NET compact framework. The JavaScript will be sent from the remote Web server. For this to work, I think the DLL must be compiled for .NET compact framework; normal .NET DLLs don't run in the CF .NET framework. I expect the DLL to reside on the PDA itself. The problem: The .NET CF has limited support for COM interop. I think the you will have to build a COM wrapper in C++ (unmanaged code) to encapsulate the COM. From my research, there exists a mechanism to pass messages from one process to another using the SendMessage method of the .NET CF. This mechanism also allows unmanaged code to call managed code using a function that's equivalent to one that's in the Windows API and which is also called SendMessage. That is, an Embedded C++ 4.0 process can call a managed code function using Windows Messaging. One likely approach is for the JavaScript call a DLL written in Embedded C++ 4.0, which in turn calls the .NET CF method using messaging from the Windows Mobile API. I can provide my VB.NET DLL (really quite simple), but you won't be able to test it because of the hardware and third-party libraries and setup required. However, if you can build a similar DLL that does simple functions (pass some parameters, do something with them, and pass back a string result) then that would be sufficient for me to apply to my own DLL. If there's a better idea out there, I'm all ears. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
