Standard Object File Format (COFF) binary files (which include DLLs, LIBs and EXEs) provide a lot of useful header information, including all of the functions that they export. VB and eVB developers, this is your opportunity to get familiar with a tool that C developers have come to rely on: dumpbin.exe. NET Compact Framework doesn't come with an API Viewer-like tool, and while the number of examples and resources on the Internet are growing rapidly, there is still no definitive code archive that will provide all the P/Invoke function declarations you'll need.

For VB developers, external functions could often be called without having a strong understanding of how to actually write the Declare statements because you had the API Viewer and pretty exhaustive online archives. NET Compact Framework is so lightweight, you, the developer, may need to P/Invoke external functions from time to time. P/Invoking is simply a methodology for calling functions that are publicly exported from a dynamic link library (DLL).īecause the. If you're a C developer you know it as a dllimport. If you're a VB developer, you know it as a Declare. Platform Invoke isn't actually new it's just a new name, so you're probably already familiar with the concept. This service allows managed code to invoke unmanaged functions residing in DLLs. NET Compact Framework (like its desktop cousin) provides developers with a fantastic 'swiss army knife' known as Platform Invoke (P/Invoke). For developers, this means that there will be some functionality that you can access only by dropping down to the operating system (Windows CE) APIs.

NET Compact Framework-specific types for dealing with user input, messaging, and SQL Server™ 2000 Windows CE Edition 2.0. NET Compact Framework supports approximately 25% of the types across the entire range of namespaces in addition to several.

NET allows developers to write managed code in Visual Basic or C# that is executed in a common language runtime analogous to that in the full. NET Compact Framework coupled with the Smart Device Project support in VS. NET 4.1 devices, and has been developed as a subset of the full. NET Compact Framework targets Pocket PC 2000, 2002, and embedded Windows CE. NET Compact Framework-based applications. Summary: Learn how to use dumpbin.exe as an aid for declaring P/Invokes in Microsoft.
