An update for Clarion.Net is out today.\u00a0 It has a good number of fixes and delivers the previously described feature that automatically exposes Procedures you select so that they are visible to Clarion Win32 Apps.\u00a0 I wrote about this a while ago, so I’ll refresh you on it (this is straight from the Help file):<\/p>\n
1) In the Clarion# Program’s GLOBAL MAP, add both the NAME and PUBLIC attributes to the PROCEDURE prototype<\/p>\n
For example in your Clarion# global Map:<\/p>\n
MAP<\/p>\n
! Procedures exposed for Win32 access must have both the NAME and PUBLIC<\/span> attributes END<\/p>\n 2) On the Clarion# Project properties dialog, turn on the checkbox: Export Global named procedures and create Clarion Win32 LIB file<\/strong><\/p>\n This step causes a .LIB file to be created, its location is set according to your RED file, or you can specify the output path in the Project<\/p>\n 3) Copy both the .LIB and the Clarion# DLL to your Win32 project folder. \u00a0You also must copy any assemblies (DLLs) that your Clarion# DLL references, for the minimum you need:<\/p>\n SoftVelocity.Clarion.Runtime.Procedures.dll <\/p>\n 4) In the Clarion Win32 program prototype the Procedure(s), and add the PASCAL and DLL attributes. If you need to pass a string value by address also add the RAW attribute.<\/p>\n MAP<\/p>\n MODULE(‘ManagedDLL.dll’)<\/p>\n ! Calling Clarion# Procedures, you must use the PASCAL Attribute and set DLL(true)<\/span> END<\/p>\n END<\/p>\n <\/p>\n In the initial implementation (its already changed internally),\u00a0 you might run into a “gotcha” when you get to step 2.\u00a0 In order to expose the Procedures for use in a Win32 program the binary Clarion# DLL file has to be disassembled back to IL code, the IL code is then modified, and then the IL code has to be assembled back to a binary (PE format) file.\u00a0 To do this there are two programs from the .Net SDK that have to be found; Ilasm and Ildasm.\u00a0 In the current implementation the location for those files is stored in an external .config file, and if they are not found (Ilasm and Ildasm), you’ll get an error message telling you to edit the path stored in Dllexport.exe.config.\u00a0 In the next release we’ll have an improved implementation that finds these automatically on all OS’s (32 or 64 bit).<\/p>\n You’ll find an easy to understand example showing how this works in the .SamplesWin32toDotNet folder.<\/p>\n","protected":false},"excerpt":{"rendered":" An update for Clarion.Net is out today.\u00a0 It has a good number of fixes and delivers the previously described feature that automatically exposes Procedures you select so that they are visible to Clarion Win32 Apps.\u00a0 I wrote about this a while ago, so I’ll refresh you on it (this is straight from the Help file): … Continue reading Clarion.Net update<\/span>
